Beyond nutmeg, mace, and cloves: Checklist of the liverworts and hornworts of Maluku Islands (Moluccas), Indonesia

TL;DR

This paper presents the first checklist of liverworts and hornworts in the Maluku Islands, Indonesia, highlighting biodiversity and suggesting more species remain to be discovered.

Contribution

The study provides the first comprehensive checklist of liverworts and hornworts for the Maluku Islands, identifying new and doubtful species.

Findings

355 accepted and 16 doubtful liverwort and hornwort species were identified in the Maluku Islands.

22 previously reported species were rejected based on new evidence.

The study suggests further fieldwork could reveal additional species in the region.

Abstract

The first ever liverwort and hornwort checklist is provided for the Maluku Islands (Moluccas/Spice Islands) of Indonesia. We report 355 accepted and 16 doubtful species and reject 22 species previously reported for Maluku Islands. The list is based on the specimens housed in the Herbarium Bogoriense (BO) and reports from over 500 literature references, including monographs, regional studies, and molecular investigations. The Maluku Islands are part of the Wallacea Biodiversity Hotspot with many unique species found only in Wallacea. Publications focusing on liverworts and hornworts of Maluku Islands are few and scattered. Considering regionally widespread species that have been recorded elsewhere, we predict that further fieldwork exploring the diversity of habitats coupled with collections unveiled from regional herbaria, a number of new records remain to be reported.

Introduction

The Maluku Islands (Moluccas) is an island archipelago of over 1,000 islands situated in eastern Indonesia south of the Philippine island of Mindanao and east of Sulawesi, scattered in a series of irregular arcs spanning the Maluku, the Banda, and the Seram Seas (Zerner 1994; Leunufna and Evans 2014). The Maluku Islands were also formerly known as the Spice Islands because the archipelago held great geopolitical significance due to the abundance in spices as a commodity (Van Gils and Cox 1994). For instance, the spice nutmeg (Myristicafragrans Houtt.) a small-holder’s crop, with 3500 years of antiquity, is indigenous to the Banda Islands, and is now grown in about 12 countries including some secondary centers of domestication (Peter 2001; Sasikumar 2021).

The biogeographical region of Maluku Islands (Fig. 1) encompasses the Indonesian geopolitical provinces of North Moluccas (Maluku Utara Province) and part of South Moluccas (Maluku Province) (Rutgrink et al. 2018). The major island groups in the north Moluccas are Halmahera, Bacan, Morotai, Obi, Sula, Ternate, and Tidore whereas Seram (previously known as Ceram), Buru, Banda, and Ambon are situated in the south. Many of the islands of Maluku are comprised of fragments of continental crusts (Monk et al. 1997) and are one of the most complex biogeographical and oceanographic areas on Earth (Pitriana et al. 2020). The island groups have experienced considerable, but very different tectonic displacements. During the last 10 million years, the North Moluccas moved westwards along the north coast of New Guinea to their current position. The Southern Moluccas moved northwards from Australia, west of New Guinea (Rutgrink et al. 2018). Not surprisingly the flora shows a marked similarity to those of New Guinea and Australia but also includes many endemic species and at least two endemic genera (Parakibara Philipson and Siphokentia Burret) (Burret 1927; Philipson 1985).

Moluccas in the Indonesian archipelago (inset) as defined in the present paper and the islands and archipelagos here used.

Famously, western exploration of the natural history of the Maluku Islands dates back to the 17^th^ century, starting with Georg Everhard Rumphius, and later, for example, Alfred Russel Wallace (Strack 1993; Lamoureux 1990). Notably, Wallace (1863), proposed a sharp boundary of the Indo-Australian Archipelago based upon land-mammal and land-bird distributions. It has since achieved iconic status and today its significance is recognized well beyond the confines of the biogeography community (Ali and Heaney 2021). Yet, it is noteworthy that the application in recent years of modern analytical techniques has not led to a consensus view on where the lines/areas should run/be placed (Ali and Heaney 2021). The Maluku Islands are part of what is termed as the Wallacea Biodiversity Hotspot, a region that covers an area of 338 thousand square kilometers with thousands of islands supporting highly diverse biological communities with many unique species found only in Wallacea (van Welzen et al. 2005; CEPF 2014). Wallacea was identified as one of the original 25 biodiversity hotspots in the world (Myers et al. 2000).

Maluku Islands are situated in the “Tropical and Subtropical Moist Broadleaved Forests” biome (Olson et al. 2001) and contribute approximately 24% of forest cover of the Wallacea land surface. The archipelago as here defined is separated into four ecoregions, eastern part of “Sulawesi Lowland Rainforests”, “Buru Rainforests”, “Halmahera Rainforests” and “Seram Rainforests” (Fig. 3, https://www.oneearth.org/bioregions/sulawesi-maluku-islands-au14/) and is considered home to much endemic flora (CEPF 2014). The Maluku Islands are one of the few places in the Indonesian archipelago where it is possible to find a complete altitudinal sequence of vegetation, with few places elsewhere in the tropics providing a comparable range (Edwards et al. 1993). Many of the forests in Maluku are lowland evergreen and semi-evergreen forests (Fig. 2), especially on Halmahera and adjacent islands, tropical montane forests, limestone (karst) geologies, and ultrabasic (serpentine) geologies (Ellen 1997; Abdo 2017).

Ecoregions of the Moluccas Islands.

Liverworts and hornworts are, together with mosses, commonly referred to as bryophytes. They represent three early diverging clades of land plants forming the second largest group of green land plants after flowering plants and are of critical biological, ecological, and phylogenetic significance. Bryophytes serve as the “macrophytes,” providing a matrix where many microscopic organisms live, including tardigrades, mites, rotifers, micro-molluscs, microalgae, microfungi, and prokaryotes (Gerson 1982; Huttunen et al. 2017; Muggia and Grube 2018). They also play an important role as possible indicators of climate change (e.g., Lindo et al. 2013; Ruklani et al. 2021), in nutrient cycling (Rieley et al. 1979) and through their water retention reducing soil nutrient loss and flooding risk (Anderson et al. 2010). Because of their physiological properties they have therefore been used extensively as ecological indicators (e.g., Pakeman et al. 2019; Déleg et al. 2021). Resolving relationships among bryophytes and their relationships to the remaining land plants is critical for understanding the evolution of fundamental innovations within land plants (Leebens-Mack et al. 2019).

Historically, relatively few publications have focused on plant collections from the Maluku Islands, despite the significance of the flora. Approximately 4,442 species of plants and fungi were recorded from Maluku Islands until 2017 (Retnowati and Rugayah 2019). Herbarium Amboinense, a classic work by Rumphius (1741–1755), contains descriptions of plants commonly found in Ambon and the surrounding islands. However, the floristic knowledge of liverworts and hornworts remains poor, especially compared to seed plants, and has scarcely been published. Seram and Ambon have been the most investigated areas for liverworts and hornworts and have been reported by several authors (e.g. Akiyama 2009; Doei 1987a, 1987b; Hasegawa 1986; Hattori 1986b; Inoue 1986; Mizutani 1986a). One of the most significant contributions to bryophytes of the Maluku Islands is the checklist of bryophytes from Seram and Ambon by Akiyama (2009) who recorded as many as 226 species of liverworts. One species, Lepidoziaintegrifolia Doei, is an endemic species of Seram (Doei 1987a).

We here present the first ever checklist of liverworts and hornworts for Maluku Islands in an effort to further promote bryological research, especially in the eastern part of Indonesia. The checklist complements recently published checklists for Indonesia including Söderström et al. (2010) for Java and Nadhifah et al. (2021) for the Lesser Sunda Islands. The significance of checklists is summarized by Söderström et al. (2008), including outlining the utility of checklists as powerful and important tools, and their applicability to taxonomy, systematics, and conservation.

Liverwort types from Maluku

Not less than 113 names (9 of them invalid) have original material from the Maluku Islands. Of the validly published names, 13 have holotypes and 47 of the rest are lectotypified. However, 43 names remain to be typified. Here we designate lectotypes, or validate earlier unsuccessful lectotypifications, for 13 names. For a discussion on lectotypification procedures, including the concept of inadvertent lectotypifications, see Söderström and Hentschel (2023). In the list below we cite the lectotypification source and indicate where further typifications are needed.

Materials and methods

Nomenclature and taxonomy follow the world checklist of hornworts and liverworts (Söderström et al. 2016) with some updates from recent literature. Sources include more than 500 publications found through the work with Early Land Plants Today (ELPT) database of liverwort taxonomy and distribution, and with some consultation with taxonomic experts. In addition, we also examined the specimens collected from the Maluku Islands in the Herbarium Bogoriense (BO). The checklist follows a similar format of a series of previous liverwort and hornwort regional checklists by the authors, e.g., Java, Lesser Sunda Islands (Söderström et al. 2010; Nadhifah et al. 2021). References citing primary reports (citing specimens or material seen by the author) are given in bold. Secondary references not citing any material seen are given in normal font. In cases where we are not aware of any primary source, or the earliest report is a secondary source without any clear connection to a primary source published later, we comment on the situation. In the current checklist we note under which name a taxon is reported except when it is reported under the currently accepted name.

We here accept reports of 355 species from the area in addition to 16 reported species that we consider as doubtful and 21 species reported whose occurrence we reject from the islands. Species number known varies a lot between the islands/archipelagos (Table 1, Fig. 4). We are not aware of a single report from Sula while 258 species are known from Seram. Thus, we expect that with further investigations the number of species will rise considerably for many of the islands in the region.

Species richness on the different islands/archipelagos of Moluccas. The darker the more species known (cf. Table 1). White (Sulu I) means that no liverwort or hornwort species are known from the area.

Chiastocaulon Carl

Chiastocaulonfimbriatum (Mitt.) S.D.F.Patzak, M.A.M.Renner, Schäf.-Verw. et Heinrichs. MOLUCCAS: Seram: Akiyama 1986, 2009 both as Plagiochilionaff.fimbriatum. Note: a Sino-Himalayan taxon very unlikely to occur in the tropics.

Conocephalum Hill

Conocephalumconicum (L.) Dumort. MOLUCCAS: Ambon: Sopacua et al. 2020 as ‘Conocephelum’ conicum [Saparua I]. Note: presumably a mainly European taxon reported sensu lato from many other places. It is unlikely that the genus Conocephalum occurs in the tropics, but if it is a Conocephalum sp. it is probably more related to Conocephalumsalebrosum than to Conocephalumconicum.

Cryptolophocolea L.Söderstr., Crand.-Stotl., Stotler et Váňa

Cryptolophocoleaconnata (Sw.) L.Söderstr. et Váňa. MOLUCCAS: Gaudichaud 1828 as Jungermanniaconnata. Note: an American species and this old record must be rejected as either mis-identified or mis-labelled.

Dendroceros Nees

Dendrocerosexalatus Steph. MOLUCCAS: Ambon: LECTOTYPE [Hasegawa 1980: 302], Stephani 1909b, 1917, Bonner 1965. Note: Stephani erroneously reported the type locality as “Amboina” but as this is a Brazilian species that must be due to mislabeling (cf. Hasegawa 1980).

Heteroscyphus Schiffn.

Heteroscyphuscaledonicus (Steph.) Schiffn. MOLUCCAS: Ambon: Miller et al. 1983. Note a Pacific species possibly endemic to New Caledonia.

Lepicolea Dumort.

Lepicoleaochroleuca (Spreng.) Spruce. MOLUCCAS: Seram: Herzog 1921. Note: an Afro-American species only once reported from SE Asia. This report must be an error.

Lepicoleascolopendra (Hook.) Dumort. ex Trevis. MOLUCCAS: Seram: Herzog 1926b. Note: an Australian/New Zealandian species frequently, but erroneously, reported from many other places.

Lepidozia (Dumort.) Dumort.

Lepidoziamicrophylla (Hook.) Lindenb. MOLUCCAS: Seram: Siregar and Pasaribu 2019. Note: a species endemic to New Zealand (cf. Engel and Schuster 2001) and all reports from other areas must be rejected.

Lepidoziarigida Steph. MOLUCCAS: Buru: ORIGINAL MATERIAL of Lepidoziarigidaf.minor, Herzog 1921 as Lepidoziarigidaf.minor, Herzog 1926a as Lepidoziarigidavar.minor. Note: a species from Vanuatu. Herzog’s material must belong to another species.

Plagiochila (Dumort.) Dumort.

Plagiochilagigantea Lindenb. MOLUCCAS: Ternate/Tidore: Nees 1830 as Jungermanniagigantea. Note: a New Zealand taxon.

Plagiochilatrapezoidea Lindenb. MOLUCCAS: Ternate/Tidore: Reinwardt et al. 1824 as Jungermanniasimplex Web, Schiffner 1900, Bapna and Kachroo 2000b. Note: Inoue (1984) designated the only specimen from Java of Jungermanniasimplex Web. that he could locate as a neotype of Plagiochilatrapezoidea and Plagiochilatrapezoidea β tenera is described as based on Jungermanniasimplex Web. However, Inoue (1984) reject the report of β tenera in Gottsche et al. (1844; all other reports probably based on this) as Plagiochilaciliata. The occurrence of Plagiochilatrapezoidea in Moluccas is therefore not confirmed and reports should be rejected following Inoue, until confirmed, although it occurs in most neighbouring islands.

Podomitrium Mitt.

Podomitriumphyllanthus (Hook.) Mitt. MOLUCCAS: Ambon: Schiffner 1890, 1898 as ‘Hymenophytum’ phyllanthus, Sydow 1894. Note: this is an Australian/New Zealandian species.

Porella L.

Porellanitens (Steph.) S.Hatt. MOLUCCAS: Long and Grolle 1990. Note: the second-hand reports from Malesia in Long and Grolle (1990) of this Sino-Himalayan species is due to supposed, but rejected, synonymy with Porellajavanica (cf. also Hattori 1978).

Pycnolejeunea (Spruce) Schiffn.

Pycnolejeuneaschwaneckei (Steph.) Schiffn. ex P.Syd. MOLUCCAS: Ambon: Schiffner 1890, Sydow 1894 as Pycnolejeunea ‘schwaneckii’. Note: this is a neotropical species.

Radula Dumort.

Radulapinnulata Mitt. MOLUCCAS: Miller et al. 1983. Note: Yamada (2002) rejected all reports from Moluccas.

Riccardia Gray

Riccardialatifrons (Lindb.) Lindb. MOLUCCAS: Ambon: Schiffner 1890 as Aneuralatifrons, Sydow 1894 as Aneuralatifrons. Note: a mainly boreal species and all reports from tropical areas should be rejected.

Schistochila Dumort.

Schistochilaneesii (Mont.) Lindb. MOLUCCAS: Ambon: Schiffner 1893b, 1898, Buch 1939, Hässel 1976 as Paraschistochilaneesii. Note: an African species rejected from Moluccas by So (2003a).

Symbiezidium Trevis.

Symbiezidiumtransversale (Sw.) Trevis. MOLUCCAS: Gaudichaud 1828 as Jungermanniatransversalis. Note: an American species.

Zoopsis Hook.f. ex Gottsche, Lindenb. et Nees

Zoopsisargentea (Hook.f. et Taylor) Gottsche, Lindenb. et Nees. MOLUCCAS: Ambon: Stephani 1908a, Del Rosario 1975b, Miller et al. 1983. Note: an Australian/New Zealandian species.

Zoopsissetulosa Leitg. MOLUCCAS: Miller et al. 1983 as Zoopsisrigida. Ambon: Schiffner 1893b as Cephaloziasetulosa, 1898, Stephani 1908b, Hattori 1951, Hodgson 1965, Schuster 1969. Note: an Australian/New Zealandian/ New Caledonian species rejected from Asia as Zoopsissetigera by Grolle and Piippo (1984).
