Reinwardtia is a peer-reviewed scientific journal dedicated to advancing the understanding of plant science, with a particular emphasis on three core areas: plant taxonomy, plant ecology, and ethnobotany. The journal serves as a vital platform for disseminating research that explores the classification, identification, and relationships of plant species (taxonomy), the interactions between plants and their environments (ecology), and the traditional knowledge and cultural significance of plants (ethnobotany). Reinwardtia places a strong focus on the flora of Southeast Asia, a region known for its rich biodiversity and complex ecosystems. It extends its coverage to neighboring regions, including the tropical areas of Northern Australia, providing insights into the plant life of these biologically diverse areas. The journal seeks to contribute to the global scientific community by publishing original research articles, reviews, and notes that deepen the understanding of plant species in these regions and their ecological and cultural contexts.

Abstract

From a recent research on Indonesian bamboo germplasm it has become evident that there are at least 43 undescribed species (6 species of Bambusa, 3 species of Dendrocalamus, 4 species of Dinochloa, 13 species of Gigantochloa, 2 species of Nastus, 2 species of Racemobambos, 11 species of Schizostachyum and 2 species in the new monotyic genera Parabambusa and Pinga). Two new genera (Fimbribambusa and Neololeba) are here separated from Bambusa Schreb.

Abstract

 1. The author considers the genus Schima monotypic. Its only species, Schima wallichii (DC.) Korth., is subdivided into nine geographically separated subspecies and three varieties.These may be recognised sometimes by one dominating chax*acter,mostly, however, by a complex of characters.Several new combinations are made.2. Yet the variability of most of the subspecies is still often enormous and at first sight appears complex. Thus we may often encounter the polymorphy of the whole species in its subspecies again. It was the striking different percentage-numbers of(phenotypically) about the same characters which turned the scale in favour of the recognition of the subspecies, besides their geographic separation.The attempts made by the author to divide certain resulting complex-polymorphous subspecies into units of still lower rank and to trace correlations with peculiarities of environment such as different heights above sealevel, or with different stages in the age of the trees, failed. 3. On account of these negative results and the above mentioned different percentage-numbers for phenotypically about the same characters, the author came to the conclusion that the most probable explanation is that the variability within the subspecies is just due to Mendel-segregation and nothing else.It looks very much as if one is dealing here with the inheriting of striking characters, each caused by one or only a few polymeric factors, characters which hold their own, just as in panmictlcally propagated populations (by cross-pollination). This explanation, too,makes the striking fact that in some subspecies we find back phenotypically the whole, or part, of the polymorphy of the entire species more understandable, as well as the fact that individuals of different subspecies may agree phenotypically, whereas genotypically they belong to different races (subspecies), Moreover, all these phenomena strongly support the monotypic conception of the genus. 4. The author saw few examples from the area outside Indonesia. However,this does neither influence his monotypic conception of the genus, nor his method of dividing it into units of lower ranks. The study of the scanty amount of specimens,literature, and the drawings seen appeared more than sufficiently convincing. Yet he is not quite certain whether the correct rank was ascribed to some of the lower taxa involved. It would perhaps have been advisable to consider the variety superba and the continental parts of the subspecies oblata and monticola as distinct subspecies.Future consideration of this matter shall have to decide.

Abstract

KALIMA, T., SUHARTI, S., SUMARHANI & TRETHOWAN, L. A. 2020. Tree species diversity and ethnobotany of degraded peat swamp forest in Central Kalimantan. Reinwardtia 19(1): 27‒54. ‒‒ Most peat swamp forest has been degraded. This has resulted in decline of its biodiversity. The objective of this study was to identify the composition, diversity, and plants used by local people in Bagantung swamp forest. The study was conducted on degraded peat swamp forest area in Bagantung, Mantangai Sub-District, Kapuas District, Central Kalimantan Province. The Shannon-Wiener (H’) and the Importance Value (IV) indices were used for analyzing the species diversity and the species importance across a number of forest plots. Useful tree species were identified by interviewing local villagers. There were 2,562 individual plants in 32 plots (each plot 20 m × 20 m). We identified 100 tree species and 16 non-tree species, from 74 genera, and 46 families. Myrtaceae, Sapotaceae, Ebenaceae, Dipterocarpaceae and Clusiaceae were the most dominant families. Large tree (H’=1.46) and small tree diversity was similar (H’=1.75). In both small and large tree size classes Calophyllum nodusum was the most dominant species. There were 16 tree species and two non-tree species used by local people for house and boat construction, furniture, handicrafts, medicine, and insect repellent.

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

The genus Balanocarpus has been regarded as distinct by reason of its calyx lobes, which do not exceed the wooden nut but which enclose the very base of it,forming a five-lobed wooden cup by the equally though slightly enlarged strongly imbricate segments of the flowering calyx.Symington has called particular attention to the fact that it seemed to lack natural generic characters,viz.satisfactory and sharply marked distinctions from other groups, as was already superficially realised by his predecessorsIn agreement with earlier suggestions by Symington, Balanocarpus is.given up,it being an artificial genus.Many of its species are referable to Shorea.Of the latter,12 species are treated,7 of which are described as new.Editor's Note.-Dr D. F. van Slooten was steadily continuing his revision of the Dipterocarpaceae when his untimely death put a stop to this most useful and painstaking task. During the last few years of his life I had the privilege to be consulted by Dr van Slooten regarding certain aspects of his work and this has made me somewhat familiar with the present paper and some of its problems. As this valuable contribution was not yet ready for the press, I ventured to put it into a definite shape to make it available rather than to leave it unpublished. Therefore, the errors that it may contain are wholly my own responsibility.-M. A. Donk.

Abstract

The scope of the monotypic genus Sara.wa.kus is enlarged to enable it to accommodate the newly described species Sarawakus sucoisus Rifai. A complete taxonomic revision of the genus is presented, in which it is shown that Sarawakus belongs to the Hypocreaceae and not to the Xylariaceae as some authors have suggested. Hypocrea gelaiinosa (Tode ex Fr.) Fr. subsp. oligotheea Penz. & Sacc. is accorded specific status as Hypocrea oligotheea (Penz. & Sacc.) Rifai and Phaeocreopsis pezizaeformis Boedijn is transferred to Hypocreopsis.
