Abstract

The Lesser Sunda Islands of Indonesia are composed of small islands scattered from Bali to Timor Island. We analyzed a molecular phylogeny of Adiantum collected from Lesser Sunda Islands to reveal its phylogenetic relationships. A total of 12 species of Adiantum from this region and seven species from Java Island were collected and used in this study. Two cpDNA regions (rbcL and trnL-F) were chosen as markers and phylogenetic analyses were conducted using Neighbour-Joining (NJ) and Maximum Parsimony (MP) methods. The tree topologies reconstructed by NJ and MP from specimens used in this study and other species downloaded from GenBank are congruent in which trees are divided into five major clades. Adiantum species of Lesser Sunda Islands are not monophyletic and comprises three clades, i. e. Clade I composed of A. hispidulum group, Clade III composed of A. peruvianum group and Clade IV or A. caudatum group, each together with extra-Lesser Sunda samples. No sample from Lesser Sunda Islands examined is located in Clade II (A. tenerum group) and V (A. capillus-veneris group).

Abstract

PURWANINGSIH, POLOSOKAN, R., YUSUF, R. & KARTAWINATA, K. 2017. Phytosociological study of the montane forest on the south slope of Mt. Wilis, East Java. Indonesia. Reinwardtia 16(1): 31 - 45. —A phytosociological stud y of a montane forest was carried out on the south slope of Mount Wilis, Kediri, East Java. The objective of the study was to do quantitative measurements of floristic composition and structure of the montane forest located within the seasonally dry climatic region as to date no such study has been undertaken there. It was conducted using the quadrat method by establishing plots of 2500 m2 each at five locations at the altitudes of 1100 m asl (above sea level), 1200 m asl, 1300 m asl, 1400 m asl and 1500 m asl, thus the total area sampled was 1.25 ha. They were Plot1100 at Bekayang, Plot1200 at Bukit Bendera, Plot1300 at Batutulis, Plot1400 at Mergosepi and Plot1500 at Brak. A total of 1045 trees comprising 74 species of 50 genera and 33 families were recorded. Based on a species constancy index of 100 %, the Saurauia nudiflora-Weinmannia blumei association was established. The association consisted of (1) the Cyathea-Polycias subassociation, representing the heavily disturbed forest, currently dominated by Cyathea contaminans and (2) the Villebrunea-Syzygium subassociation, representing the least disturbed forests, dominated by Syzygium lineatum and Villebrunea rubescens. The lowest number of species (13) was recorded in Plot1100 and the highest number (39) in Plot1300. Important species recorded included Cyathea contaminans (Importance Value, IV= 47.97); Lithocarpus sp. (IV= 22.07); Lithocarpus sundaicus (IV= 14.05); Saurauia pendula (IV= 12.85); Villebrunea rubescens (IV= 12.12) and Syzygium lineatum (IV= 11.22). Diameter measurements showed that 76.60 % of trees in Plot1100 and 86.60 % in Plot1200 consist of small individuals with diameters between 10 and 30 cm. Trees with large diameters of >30 cm occurred in Plot1300, Plot1400 and Plot1500. The presence of large numbers of small trees and lesser numbers of trees with large diameters in a forest stand indicated that the stand was regenerating after heavy disturbance. The presence of the majority of trees with height of < 20 m (99 %) further confirmed the forest’s dynamic status.

Abstract

In the S. E. Asiatic genus Spatholobus 28 species are recognized, 6 of which are never described before: S. albus S. auricomus, S. auritus, S. hirsutus, S. multiflorus and S. viridis. One variety (S. ferrugineus var. acutus) is also newly described. A key and full descriptions with plates and maps to illustrate the distribution are given.
ATUNA RAFIN. versus CYCLANDROPHORA HASSK. (Rosaceae-Chrysobalanoideae) a. j. g. h. kostermans

Abstract

Atuna Rafinesque(Sylva Tellur.153. 1838)with a single species Atuna ra-cemosa Rafin. has priority over Cyclandrophora Hasskarl (in Flora 25(2), Beibl. 1: 47. 1842) and as it has been described properly it has precedence over Cyclandrophora. I formerly (in Candollea 20: 118. 1965) preferred to reinstate Cyclandrophora as there is a generic name Atunus [Rumph.] Lamarck 1797, a synonym of Heritiera Dryander (Sterculiaceae). After sounding out some experts in this matter,it has become evident, that the chances to conserve Cyclandrophora against Atuna are slight and hence I give here the new combinations of the species of this genus.

Abstract

This is a fully descriptive account of the 108 species of Carex known to occur in Malaysia. They are arranged in three subgenera: Subgenus Indocarex Baill. (43 species), Subgenus Carex (Eucarex Coss. et Germ.) (57 species), and Subgenus Vignea (P. Beauv.) Nees (8 species). These are in turn divided into 33 sections. The classi- fication of these Malaysian Carices differs radically from past systems (cf. that of Kiikenthal, Engl. Pflanzenreich, 1909) and is based on the phylogenetic views of the author. Following the descriptions are citations of all the specimens seen by the author, and a few not seen but which have mainly been determined' by Kiikenthal. The majority of the specimens Came from Bogor (Buitenzorg) (about 1500 sheets) and Leiden (about 600, including important historical specimens). About half of the species are restricted (endemic) to one or another of the 'island areas' into which Malaysia can be conveniently divided: 18 species in New Guinea, 10 in the Philippines, 5 in Borneo and in Sumatra, 4 in the Malay Peninsula, 3 in Java and in Celebes, 2 in the Moluccas, and 1 in the Lesser Sunda Islands. The remaining 58 species have a slightly to much wider distribution, the chief connection being with India, and, to a slightly less extent, Japan and China. Keys are provided to the species as a whole, to the subgenera, the sections, and to the species in each section. The introductory part of the work explains, among other things, the classi- fication, the relative taxonomic value of characters in the descriptions, distribution, and sources of the material,.

Abstract

Since a large number of characters are now known for Freycinetia Gaudich. and Pandanus Parkinson species, it appears useful to consider their use in identifying plants from Java. Fieldwork carried out for this study has provided stronger foundation for understanding morphological variation within the species. This study was undertaken to have a better understanding on the morphology of the family in order to make a better species delimitation. Characters of habit, stem, leaves, auricles, bracts, peduncle and pedicel, inflorescence, staminate flowers (male), pistillate flowers (female), cephalia and berries were found useful in delimitation and identification of Javanese Freycinetia, while characters of habit, stem, prop root, marginal spine, leaves, bracts, inflorescentia, peduncle, staminate flowers (male), pistillate flowers (female), cephalia, drupes were found to be useful for distinguishing among species of Javanese Pandanus.

Abstract

A new subdivision is given of the fern family Gleicheniaceae. The genus Platyzoma R. Br is excluded from the family. The genus Stromatopteris from New Caledonia is arranged in a distinct subfamily. In the remainder of the family, subfamily Gleichenioideae, two genera are recognized, Gleichenia (with subgenera Diplopterygium, Gleichenia, and Mertensia) and Dicranopteris (with subgenera Acropterygium and Dicranopteris) . The problem of subdividing the family is discussed with reference to former treatments and to new data, and a conspectus of the new system, with synonymy and key to the genera and subgenera, is given. A number of new species, new varieties, and new combinations is made both in Gleichenia and Dicranopteris.

Abstract

RAHAYU, S. &  ASTUTI, I. P. 2018.  Hoya decipulae (Apocynaceae, Asclepiadoideae), a new species from Sumatra, Indonesia. Reinwardtia 18(1): 61‒67. ‒‒ The new Hoya species from Sumatra, Hoya decipulae S.Rahayu & Astuti is here described and illustrated. It is an epiphytic shrub, thin-leaved with white flowers, similar to those of H. papaschonii Rodda, but differs in corolla and corona form.  Its corolla has a unique characteristic of forming a “cage” before fully opening, as a result of the attachment of the five corolla tips which are free at the centre. The corona does not have interstaminal lobes as in Hoya papaschonii.  Its corona resembles that of H. multiflora Blume and H. irisae Ferreras, Kloppenburg & Tandang from the centre to the tip but differs at the base.
