Abstract

ADILI, A., KARTAWINATA, K., SOEDJITO, H. & SAMBAS, E. N. 2018. Tree species diversity in a pristine montane forest previously untouched by human activities in Foja Mountains, Papua, Indonesia. Reinwardtia 17(2): 133‒154. ‒‒ A study on structure and composition of the pristine montane forest previously untouched by human activities was conducted at the Foja Mountains in November 2008. We established a one-hectare plot divided into 100 subplots of 10 m × 10 m each. We enumerated all trees with DBH ≥ 10 cm which diameters were measured, heights were estimated and habitats were noted. We recorded 59 species, 42 genera and 27 families, comprising 693 trees with the total basal area (BA) of 41.35 m2/ha. The forest had lower species richness compared to those of lowland forests in Kalimantan, and Sumatra and montane forests in West Java. The Shannon-Wiener’s diversity index was 3.22. Nothofagus rubra (Importance Value, IV=47.89%) and Parinari corymbosa (IV=40.3%) were the dominant species, constituting the basis for designating the forest as the Nothofagus rubra - Parinari corymbosa association. To date, the dominance of N. rubra is unique to the Foja Mountains, as elsewhere in Papua the montane forests were dominated by N. pullei or other species. The species-area curve indicated a minimal area of 5000 m2. On the family level Fagaceae (IV=53.23%), Chrysobalanaceae (IV=40.53%) and Myristicaceae (IV=26.43%) were dominant. Verti-cally the forest consisted of four strata (A–D). In each stratum Nothofagus rubra, Platea latifolia, Parinari corymbosa and Myristica hollrungii were dominant. The diameter class distribution of Nothofagus rubra, Parinari corymbosa and Platea latifolia led us to assume that these species were regenerating well.

Abstract

Two new species of Begonia, Begonia holosericeoides Ardi & D. C. Thomas and B. aketajawensis Ardi & D. C. Thomas, are described from Aketajawe Lolobata National Park, Halmahera, Indonesia. The two species belong to Begonia section Petermannia. Begonia  holosericea, previously only tentatively assigned to a section, is here assigned to section Petermannia based on the examination of newly available material. Additionally, a revised description and an illustration are provided. A key to the Moluccan species of Begonia is presented.

Abstract

A full taxonomic study of the genus Cyathea has recently been published in Flora Malesiana (Ser. II, vol. 1, part 2, Dec. 1963). In that work the genus is construed in a broad sense, to include Alsophila and Hemitelia (also Gymnosphaera and Schizocaena of Copeland's Genera Filicum), the total number of species being 191, and a new subdivision of this comprehensive genus is proposed. The keys in Flora Malesiana, dealing with such a large number of species, are complex, and not very easy to use for local purposes. I have therefore made a simpler key to cover the species of java only, and hope this will be of service to botaniists in Java.

Abstract

ASTUTI, I. P. & RUGAYAH. 2016. A new species of Murraya from Cyclops Mountain, Papua, Indonesia. Reinwardtia 15(2): 111 –114. — A living collection of Bogor Botanic Gardens, planted in plot XXIV.A.192-192a and originated from Kemiri Said Nature Reserve, Cyclops Mountain in Papua collected by Lugrayasa (LG 1352), is described and illustrated as a new species, namely Murraya cyclopensis Astuti & Rugayah. The species is closely related to Murraya paniculata (L.) Jack, in vegetative and flower structures, but differ in the presence of indumentum on twig, rachis and petiole, smaller size of flowers, red globose fruits, and orbicular seeds covered by densely short hairs and red aril.

Abstract

In Ceylon 4 endemic species of Vatica occur of which one. (Vatica obscura) occurs as a riverine species in the dry zone, the other three are restricted to the wet zone, two of them on well drained soils, one (V. paludosa) in marshy places. Vatica lewisiana is removed from CotyleloHuni and again asigned to Vatica. Vatica, paludosa Kosterm., sp. nov. is neither identical with V. roxburghiana, an Indian species, nor the same as V. chinensis L., a species of unknown origin, to which the Ceylonese material has been referred formerly.

Abstract

The Malesian genus Ceplialomappa Baillon has been revised. Five species have been recognized based on morphological and anatomical characters, e.g. C. beccariana, C. lepidotukt, C. malloticarpa, C. paludicola, C. penangensis, and four varieties within C. beccariana.The genus Muricococcum has been reinstated,the single species M. sinense is considered to differ significantly from the species of Cephahmappa to warrant generic recognition. A phylogenetic analysis of the genus, with Koilodepas as outgroup, shows the species to branch off sequentially, the first is C. paludicola, followed by C. malloticarpa, C. lepidotula, and finally C. penangensis and C.beccariana. All varieties of C. beccariana group together as a single terminal polytomy.

MAHYUNI, R., KUSUMA,Y. W. C., WIHERMANTO & VELDKAMP, J. F. 2015. Notes on Rafflesia (Rafflesiaceae) in Sumatra with a new record Rafflesia gadutensis Meijer. Reinwardtia 14(2): 317 - 322. Pulau Mursala is a small island west of the Sibolga, Tapanuli Tengah District, North Sumatra, Indonesia. The occurrence of the genus Rafflesia (Rafflesiaceae) there has never been reported before. However, during a visit in April 2013 three populations are located close together with more than twenty buds and some rotting blooming flowers, Tetrastigma sp. was detected. Field observations could be made and material was collected for comparison with that in the Herbarium Bogoriense (BO). It was concluded that they are R.gadutensis Meijer, which is known from Padang, Ulu Gadut. Notes on its morphology are given. The distribution of species is discussed.

The American species of Phoebe Nees are relegated to Cinnamomum Trew; the reasons for this transfer are discussed. To retain nomenclatural stability the new combinations which have become necessary are presented, in anticipation of a general revision of the genus Cinnamomum; 68 new combinations and names are presented.

Abstract

In working up the genus Coelostegia,I received on loan from the Forest Research Institute at Kepong,Malaya abundant material of a species which Wyatt-Smith was unable to place.Dr. Kostermans pointed out to me that most likely the specimens belonged to a new genus, related to Coelostegia I have taken the liberty to name the genus after Dr. A. J. G. H. Kostermans who has been devoting time and energy teaching me taxonomy, and who Jias taken up the burden of the development of taxonomic botany in Indonesia.I am indebted to Prof. Dr. C. G. G. J. van Steenis and to Dr. R. G Bakhuizen van den Brink Jr., who have kindly helped me in preparing the Latin diagnoses.

Abstract

The Umbilicariaceae are a family of Lichens occurring almost exclusively in temperate regions and moreover frequently growing on rocks. Nevertheless this family is represented in the tropics; it has been reportedfrom tropical America and Africa. As far as data are available they occur on rocks in the upper regions of high mountain-ranges, viz. of the Andes of Bolivia and Peru and of Pico d'Orizaba in Mexico from 10,000 feet upwards. For Africa the data are in accordance: Mount Deschen in Abyssinia (14,200 feet) and Mount Kilimanjaro in Kenya (12,000 feet). For the tropics of Asia an early record exists of the appearance of a species of Umbilicaria; until today, however, this indication has not yet been confirmed and as far as I could gather, it has remained the only one. In Zollinger's "Systematisches Verzeichniss der im indischen Archi- pel gesammelten Pflanzen," page 8, 1854, one reads: "Ad rupes summi M. Ardjuno (11,000') occurrit Umbilicariae spec, sed nunc in herbario caret." In Moritzi's "Systematisches Verzeichniss der von H. Zollinger in den Jahren 1842—1844 auf Java gesammelten Pflanzen," 1845-1846, Umbilicaria is not mentioned, although Zollinger climbed Mount Ardjuno in 1844 and the material was collected probably in that year. Later workers on Zollinger's lichens did not describe an Umbilicaria from his collections either, so that we may assume it has been lost. On July 20, 1932 and some years later, on March 27, 1937, I ascended the summit of Mount Ardjuno myself and am rather confident that I collected my specimens of Umbilicaria from the same rock as Zollinger did almost a century ago. Up there, just beneath the top at about 3,300 m, there are only a few big rocks on which this species grows. The top itself is 3,339 m. In the somewhat lower surroundings of the top I could not locate any other specimen. On the summits of Mount Welirang (3,156 m), Northern Kembar (3,020 m), Southern Kembar (3,100 m), and Mount Bakal (2,980 m), which all belong to the Mount-Ardjuno complex, I failed to discover Umbilicaria, too. The same holds true for Mount Kawi (Butak;
