4. the Plant Diversity of Singapore
FLORA OF SINGAPORE (Vol. 1: 37–46, 2019) 4. THE PLANT DIVERSITY OF SINGAPORE K.M. Wong & S.K. Ganesan The position of Singapore on the Sunda continental shelf is a special one, with the principal island originally about 540 km2 in extent, together with some 60 smaller islands at the southern exit to the Malacca Strait and near the confluence of the South China Sea and Karimata Strait just west of Borneo. Geographically at the equatorial extremity of the Malay Peninsula, Singapore is separated from the Riau islands to its south (principally the Karimun Islands, Batam and Bintan) by the Singapore Strait which includes the deeply scoured 204-m ‘Singapore Deeps’, a likely subsidence basin resulting from tectonic movements (Bird et al., 2006). While this Strait may seem able to restrict the dispersal of some organisms with interglacial and post- Pleistocene high sea levels, it probably was not an effective dispersal barrier during episodes of lowest sea levels, such as during the Last Glacial Maximum (LGM) at 18 ka. Then, it must have been in the path of a key land bridge between mainland Southeast Asia farther north and likewise exposed links to Java and other areas to the south (Ho, 1960; Morley & Flenley, 1987; Heaney, 1991; Voris, 2000; Bird et al., 2005). By contrast, the Johor Strait that separates Singapore from south Peninsular Malaysia is just about 10 m deep and 600 m wide at its narrowest. The Sundaland region on the Sunda continental shelf has seen climate shifts since even before the Pleistocene, sometimes associated with tectonic events. -

DNA Barcoding Confirms Polyphagy in a Generalist Moth, Homona Mermerodes (Lepidoptera: Tortricidae)

We evaluated the species concept for a common generalist moth occurring in New Guinea and Australia, Homona mermerodes, in light of host plant records and mitochondrial cytochrome c oxidase I haplotype diversity. Genetic divergence among H. mermerodes moths feeding on different host tree species was much lower than among several Homona species. Genetic divergence between haplotypes from New Guinea and Australia was also less than interspecific divergence. Whereas molecular species identification methods may reveal cryptic species in some generalist herbivores, these same methods may confirm polyphagy when identical haplotypes are reared from multiple host plant families. A lectotype for the species is designated, and a summarized bibliography and illustrations including male genitalia are provided for the first time. -

Five New Combinations and One New Name in Rubiaceae from South-East Asia
BLUMEA 50: 575–578 Published on 14 December 2005 http://dx.doi.org/10.3767/000651905X622860 FIVE NEW COMBINATIONS AND ONE NEW NAME IN RUBIACEAE FROM SOUTH-EAST ASIA AARON P. DAVIS & MARKUS RUHSAM The Herbarium, Royal Botanic Gardens, Kew, Richmond, Surrey, TW9 3AE, United Kingdom SUMMARY Five new combinations and one new name are proposed for six Rubiaceae species from South-East Asia. Four new combinations are proposed in Cyclophyllum and one in Psychotria; a new name is proposed for one Psychotria species. Key words: Amaracarpus, Canthium, Cyclophyllum, Plectronia, Psychotria, Rubiaceae, South-East Asia. INTRODUCTION Taxonomic studies in the Rubiaceae by Bridson (1987) and Davis & Bridson (2004) enumerate species for which new combinations are needed. Herein we take the oppor- tunity to propose five new combinations and one new name (nomen novum), as based on the aforementioned studies, viz. Cyclophyllum caudatum (Valeton) A.P. Davis & Ruhsam, C. longiflorum (Valeton) A.P. Davis & Ruhsam, C. novoguineensis (Miq.) A.P. Davis & Ruhsam, C. valetonianum (S. Moore) A.P. Davis & Ruhsam, Psychotria montisgiluwensis A.P. Davis & Ruhsam, and P. montisstellaris (P. Royen) A.P. Davis & Ruhsam. NEW COMBINATIONS IN CYCLOPHYLLUM Cyclophyllum Hook.f. (Vanguerieae Dumort.) is a genus restricted to SE Asia, Aus- tralasia and the Pacific (see Bridson 1987: 614, map 1). Bridson (1987: 616) lists eight species of Canthium Lam. that should be considered for transfer to Cyclophyllum, viz. Canthium barbatum (Forst.) Seem., C. brevipes Merr. & L.M. Perry, C. caudatum (Valeton) S. Moore, C. coprosmoides F. Muell., C. costatum C.T. White, C. longi- florum (Valeton) Merr. & L.M. -

Summary Report on Forests of the Mataqali Nadicake Kilaka, Kubulau District, Bua, Vanua Levu
SUMMARY REPORT ON FORESTS OF THE MATAQALI NADICAKE KILAKA, KUBULAU DISTRICT, BUA, VANUA LEVU By Gunnar Keppel (Biology Department, University of the South Pacific) INTRODUCTION I was approached by Dr. David Olson of the Wildlife Conservation Society (WCS) to assess the type, status and quality of the forest in Kubulau District, Bua, Vanua Levu. I initially spent 2 days, Friday (28/10/2005) afternoon and the whole of Saturday (29/10/2005), in Kubulau district. This invitation was the result of interest by some landowning family clans (mataqali) to protect part of their land and the offer by WCS to assist in reserving part of their land for conservation purposes. On Friday I visited two forest patches (one logged about 40 years ago and another old-growth) near the coast and Saturday walking through the forests in the center of the district. Because of the scarcity of data obtained (and because the forest appeared suitable for my PhD research), I decided to return to the district for a more detailed survey of the northernmost forests of Kubulau district from Saturday (12/11/2005) to Tuesday (22/11/2005). Upon returning, I found out that the mataqali Nadicake Nadi had abandoned plans to set up a reserve and initiated steps to log their forests. Therefore, I decided to focus my research on the land of the mataqali Nadicake Kilaka only. My objectives were the following: 1) to determine the types of vegetation present 2) to produce a checklist of the flora and, through this list, identify rare and threatened species in the reserve 3) to undertake a quantitative survey of the northernmost forests (lowland tropical rain forest) by setting up 4 permanent 50 ×50m plots 4) to assess the status of the forests 5) to determine the state and suitability of the proposed reserve 6) to assess possible threats to the proposed reserve. -
(Rubiaceae) Wright Amaracarpus (E.G. Perry, Separated from Amaracarpus by (Characters for Amaracarpus Are Given in Parenthese
BLUMEA 46 (2001) 421-446 A taxonomic revision of the genus Dolianthus (Rubiaceae) Aaron+P. Davis & Diane+M. Bridson Summary A taxonomic revision of Dolianthus C.H. Wright(Rubiaceae-Psychotrieae) is presented, including full distribution and list of examined. Eleven a key to species, descriptions, maps, a specimens transferred species are from Amaracarpus to Dolianthus, resulting in ten new combinations. Two species are described as new to science: D. kairoi and D. ovatifolius. In total, thirteen species are included in Dolianthus. Dolianthus is endemic to the highlands (montaneto subalpine and alpine zones) of Papua New Guinea. Key words : Amaracarpus, Dolianthus, Psychotria, Psychotrieae, Papua New Guinea. Introduction DolianthusC.H. included in Wright was formerly Amaracarpus (e.g. Merrill& Perry, 1946; Van Royen, 1973), but morphological studies show that it is a distinct genus (Davis & Bridson, in prep.). Dolianthus can be separated from Amaracarpus by at least six characters for (characters Amaracarpus are given in parentheses): sympodial shootarchitecture leaves (monopodial); arranged in many planes (in one plane); termi- nal inflorescences(axillary); pentamerous flowers (predominately tetramerous); large multi-coloured brightly or corollas, e.g. blue and yellow (small and white); anthers positioned above the ring of corolla throat hairs (within). Dolianthus differs from Psychotria L. s.s. (Davis et al., 2001) mainly due to the colour of its flowers and the position ofthe anthers in the corolla tube (see above). MATERIALS AND METHODS Herbarium material was consulted from the following herbaria; A, B, BM, BO, K, L, NY, SING, and US. The measurements, colours and other details given in the de- scriptions are based on herbariumspecimens, or data derived from field notes.
