Abstract

Codonoboea is the largest genus of Gesneriaceae in Peninsular Malaysia with 92 species. Nine sections, Boeopsis, Codonoboea, Didymanthus, Glossadenia, Heteroboea, Pectinati, Reptantes, Salicini and Venusti, have been erected based on morphological characters, such as habit, leaf arrangement and shape, type of inflorescence, number of flowers, corolla type and nectary type. Recent molecular phylogenetic study using ITS and trnL-F sequences show that only section Heteroboea is monophyletic. While the sections of Codonoboea can no longer be maintained as formal taxonomic taxa, as informal groupings they are useful in identification and in constructing keys.

Abstract

A total of 126 species are currently named and described from Borneo (Brunei - 16 species, Kalimantan – 5 species, Sabah – 41 species and Sarawak – 72 species). However, based on our survey of the begonia collection in the Sarawak Herbarium, the un-named taxa (about 110 species) significantly outnumber the 72-named species. The situation is probably the same for Sabah, so with many more new species than the 41 named ones at a conservative estimate the Sabah begonia flora can be expected to exceed 100 species. For Kalimantan (5 named species), the total number of un-named species is likely to be even higher considering that Kalimantan occupies a larger land area, its begonia-rich mountains and limestone areas are hardly collected, and the begonia flora has hardly been studied at all. We can therefore expect the begonia flora of Borneo to exceed 600 species. In view of the high level of narrow endemism (80% of species are known from a single locality), expeditions to unexplored areas are necessary to document, in particular, areas that are experiencing irreversible land-use change. Alpha-taxonomy on a large scale is needed to tackle the backlog of literally hundreds of new undescribed species.

Abstract

KIEW, R. 2015. Chionanthus (Oleaceae) in Sulawesi, Indonesia, including three new species. Reinwardtia 14(2): 287 - 295. - The genus Chionanthus (Oleaceae) in Sulawesi is revised. Nine species are described of which C. kostermansii Kiew, C. sordidus Kiew and C. sulawesicus Kiew are new species. Four species are endemic, C. celebicus Koord., C. sordidus, C. stenurus (Merr.) Kiew and C. sulawesicus. The geographic range of C. cordulatus Koord. extends to Borneo and Mollucas, while C. kostermansii also occurs in Sumbawa and Flores, and the range of C. rupicolus (Lingelsh.) Kiew extends to Sumbawa, Mollucas, New Guinea and the Bismarck Archipelago. Chionanthus polygamus (Roxb.) Kiew and C. ramiflorus Roxb. are both widespread species, the former from Sumatra to New Guinea and the latter from continental Asia to the Solomon Islands. A key to identify the species is provided. Chionanthus gigantifolius Koord. remains incompletely known.

Abstract

KIEW, R. 2020. Towards a Flora of New Guinea: Oleaceae. Part 1. Jasminum, Ligustrum, Myxopyrum and Olea. Reinwardtia 19(1): 1‒25. ‒‒ Oleaceae in New Guinea is represented by five genera and about 32 species, namely Chionanthus (about 16 species), Jasminum (10 species), Ligustrum (3 species), Myxopyrum (2 species) and Olea (1 species). A key to genera as well as descriptions of and keys to species of Jasminum, Ligustrum, Myxopyrum and Olea are provided. Of the three Ligustrum species, L. glomeratum is widespread throughout Malesia, L. novoguineense is endemic and L. parvifolium Kiew is a new endemic species. Six species of Jasminum are endemic (J. domatiigerum, J. gilgianum, J. magnificum, J. papuasicum, J. pipolyi and J. rupestre). Jasminum turneri just reaches the northern tip of Australia; of the two species from the Pacific Islands J. simplicifolium subsp. australiense just reaches SE Papua New Guinea and J. didymum, a coastal species, reaches into Malesia as far north as E Java; J. elongatum is widespread from Asia to Australia. Neither Myxopyrum species is endemic: M. nervosum subsp. nervosum extends from Peninsular Malaysia to Indonesian New Guinea, and M. ovatum from the Philippines to the Admiralty Islands. The sole species of Olea, O. paniculata, stretches from Java to Australia and New Caledonia.
