Abstract

A study on the affinity of undescribed taxa of Amorphophallus with A. paeoniifolius and its related species was undertaken using numerical analyses of data derived from preserved and living specimens. The results obtained were compared with the system of classification produced by classical taxonomic methods. The Javanese wild and cultivated forms of Amorphophallus paeoniifolius respectively known locally as "Amorphophallus campanulatus f. hortensis" and "Amorphophallus campanulatus f. sylves-tris" were confirmed as two distinct but closely related taxa.

Abstract

This revision of the Malaysian genera of Nelsonieae,of which an emended description is given, covers three genera, Staurogyne Wall.(52 species),Nelsonia R. Br.(1),and Elytraria Vahl (2).A new subdivision of Staurogyne is proposed.Among the new taxa described are 24 species (including 1 variety raised to specific rank) and 18 varieties. Moreover,4 new combinations and 1 new name are proposed.

Abstract

PRITCHETT, R., PHILLIPS, A., MARDIASTUTI, A. & POWLING, A. 2016. Rattan diversity and broad edaphic niches in a tropical rainforest of Buton, Sulawesi, Indonesia. Reinwardtia 15(2): 99 – 110. — This paper attempts to answer the question: how can at least 20 species of rattan palms in the genus Calamus (family Palmae (Arecaceae)) co -exist in a rainforest? A survey of rattans was made in Lambusango Forest on Buton, an island close to south east Sulawesi, in Indonesia. Rattan species and numbers were recorded in 87 quadrats of 30 × 10 m, laid out along linear transects in habitats with a variety of soils. Evidence for edaphic (soil) niches was sought. Different rattan species were found to be adapted to soils with different conductivity and pH values. Standardised mean difference (d) scores were calculated for pairs of species based on their response to soil pH. Of the 66 pairs tested, 61 were found to be significantly different statistically. Such differences suggest, but do not prove, that many species occupy different edaphic niches. It was found that species which show a preference for soils with intermediate pH values (5.0 to 6.5) can grow in soils with a wide range of pH values, implying broad edaphic niches and that competition between these species is weak. Correspondence analysis shows that many species do not distinguish greatly between many soils with intermediate pH values. It is concluded that rattan species show evidence for having different edaphic niches, although the niches for many species are broad. It is speculated that many rattan species may be ecologically equivalent and that a weak version of ecological neutrality theory may apply.

Abstract

We studied  the floristic compostion and structure of mangrove forests and mangrove species distribution at the Raja Ampat Regency, West Papua  We sampled the forests using (10x10 m) quadrats to record trees and saplings  laid out contiguously along 9 transects of 60 – 450 m long,  stretching perpendicularly from the coastlines or riverbanks to the landward borders. Seedlings were sampled using a 1x1 m subplot nested in each quadrat.  The transects were established on the islands of  Batanta (6), Salawati  (2). and Waigeo (1).  Within quadrats and transects we recorded 17 mangrove species of trees with density of 768 stems/ha and basal area of  37.82 m2/ha and tree height of  10 – 30 m.   Two species possessed  the highest importance value  (IV) , frequency, density and basal area  i.e. Rhizophora apiculata (IV=168.06 %) and  Bruguiera gymnorrhiza (IV=67.18).  They also showed the highest similarity in their distribution,  indicating highest degree of association.  The mangrove at Raja Ampat may, therefore,  be designated as the Rhizophora apiculata-Bruguiera gymnorrhiza Association. Other species with highest degree of distributional similarities but with low densities, basal areas and importance values were Barringtonia racemosa, Excoecaria agallocha, Hibiscus tiliaceus, Inocarpus fagifera,  Lumnitzera littorea and Sterculia shillinglawii,  of which four of them are not  true mangrove species, usually growing on less saline and more solid soils. The floristic composition of the transects in the three islands showed relatively high similarities of about 70 % and at higher similarities the transects in Batanta Island formed four groups, Salawati Island two groups and Waigeo Island one group.The Bray-Curtis polar ordination  resulted in four groups  of transects, which were related to the habitat  conditions and the length of the transects. Species diversity in the islands was very low, where the  Shannon diversity index  ranged  from  0.19 to 0.64 giving  the average  of 0.42. Rhizophora apiculata and Bruguiera gymnorrhiza  were gregenerating well and in the future they will remain dominant.  The mangrove forests of the Raja Ampat Islands by any means should be maintained as green belts and  protected from all kinds of destruction and should be made into conservation areas in order to sustain its ability to provide ecological services  and non-destructive economic benefits.

Abstract

At various times during the last four years Mr.M.Sachlan,of the Laboratory for Inland Fisheries at Bogor, Java, has sent us collections of freshwater algae from the larger islands of the Indonesian Archipelago,-Borneo, Java and Sumatra.To him we express our sincere thanks for his care and effort in obtaining this material,and for affording us the opportunity of studying it.A report on the algae is in course of preparation, and will be published on completion.During our examination we have encountered some curious cases of dichotypy in a species of Staurastrum, involving four different forms, which, if considered separately, might be thought to belong to four different species. They throw a new light upon the relationship between St. wildemani Gutw.and St. subtrifurcatum var. majus West & West, whose similarity has been noted and commented upon by other authors.(Schmidle, 1902, p. 73; Gutwinski, 1902, p. 605; West & West, 1907, p. 215; Krieger, 1933, p. 209; Rich, 1935, p. 151; Fritsch & Rich, 1937, p. 213).

Abstract

In Martius, Fl. Brasil. 12 (3): 12. 1886 (in observ.) K. Schumann described a specimen (Peckolt 628) collected in Cantagallo (Rio de Janeiro), conserved in the Brussels Herbarium and marked by Martius Sterculia rex (after the local name Pao del Rey); he suggested to name it Basiloxylon rex, if it should prove to be new; the name is consequently not valid under the Rules, but it was validated by Schumann in the same year (in Berichte deutsche bot. Gesellsch. 4: 82, t. 3. 1886). The latter description was based partly on the specimen Glaziou 10310.

Abstract

In "Reinwardtia" (1: 157. 1951) I published a new species of Viburnum from Mount Kinabalu, Borneo, under the name of V. clemensae.The description was drawn up after fruiting specimens in the Herbarium of the Arnold Arboretum. Unfortunately flowers were wanting in the specimens available.Some time ago Dr. A. J. G. H. Kostermans came across much more complete material among the indeterminata of the Bogor Herbarium, profusely flowering as well as fruiting. This enables the amplification of the description.

Abstract

In the light of recent monographic studies it has been found necessary to augment and revise to some extent the treatment of Javanese Pandanaceae in Backer & Bakhuizen van den Brinks "Flora of Java". Several name changes are suggested and some species omitted by these authors are enumerated. Notes on various species of different origin now cultivated in the Hortus Bogoriensis are also included. Pandanus sect. Multispina Fagerlind is reduced to a subsection of Pandanus sect. Rykia.
