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

Of the genus Caryodapknopaia 7 species are known, of which two are described here for the first time.The genus occurs from Yunnan to Indochina,with the exception of C.tonkinensis,which goes as far as the Philippines and Borneo. Apparently most species are distributed by water and C.tonkinensis is assumed to have spread from the mainland to Borneo during the glacial period,when a land connection existed.The genus is related to Nothaphoebe and Alseodaphne and hence belongs to Perseae.

Abstract

MULYANINGSIH, TRI. & RIDSDALE, C. E. 2002. The Bornean genus Hypobathrum (Rubiaceae). An investigation of its characters and taxonomic status. Reinwardtia 12(1): 95–116.The investigation on the characters and taxonomic status of the Bornean genus Hypobathrum was based on morphological observations of 140 specimens in Herbarium Borgoriense. The present study shows that there are 24 species that can be recognised. There are six species already placed in the genus (H. frutescens, H. longifolium, H. microcarpum, H. racemosum, H. salicinum and H. venulosum), three species require new combinations (H. coniocarpum, H. gracile, and H. rufidulum), one species requires a new combination and a new status (H. hirtum), a new name in Hypobathrum is required for one species (H. lancifolium). In the present study twelve new species are proposed (H. bangueyense, H. caudifolium, H. collinum, H. ellipticifolium, H. glaberrimum, H. glabrum, H. lithophilum, H. palustre, H. rheophyticum, H. riparium, H. sampitense, and H. subulatum). In addition, one incompletely known species is mentioned.

Abstract

The genus Durio comprises, as far as known, 27 species. The centre of distribution is Borneo with 19 species, followed by Malaya with 11 species and Sumatra with 7 species. It is likely, when Sumatra will be better explored, that this island will prove to have many more species. An exclave of the area of distribution is found in Burma, where one endemic species occurs. The common Durio zibethinus Murr. probably originated in Borneo or in Sumatra. It is now widely cultivated outside of its former area and in many places it has become spontaneous. The genus Durio is subdivided into two subgenera: Durio and Boschia Kosterm. & Soegeng, according to the way of dehiscence of the anthers (with a longitudinal slit in the former, with an apical pore in the latter). A key to the species is proposed. A map is added, to show distribution and endemism. Each species is amply described and provided with a drawing . Economic and ecological data are given.

SARI, R., HUDA, M., SUSANDARINI, R. & ASTUTI, I. P. 2019. Rafflesia hasseltii Suringar (Rafflesiaceae): A new record to Kalimantan, Indonesia. Reinwardtia 18(2): 65–70. –– Rafflesia hasseltii Suringar flower has been observed for the first time in Sambas District, West Kalimantan by the Flora Fauna Research Team during the Khatulistiwa Expedition organized by Special Forces Command of Indonesian Army in 2012. This finding is the first record of Rafflesia hasseltii in Kalimantan following the previous record in Sarawak. The flower has 5–6 perigone lobes. This paper presents the detail characteristic of the flowers.

Abstract

Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarifyvegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 x 10 m2 in abandoned plantation and 11 of 20 x 20 m2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swieteniamacrophylla –Agathisdammaa community in abandoned plantation where had a land use history of clear felling.Maesopsiseminii–Cyathea spp. community had a history of severe human disturbance. Fagaceae-Schimawallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses, and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery.
THE IDENTITY OF HORNERA Jungh. (Thymeleaceae) A. J. G. H. KOSTERMANS

Abstract

Dr. Airy Shaw (Van Steenis, Fl. Males. Ser. I, 6(1): 48. 1960),referred Hornera Jungh.(Tijdschr. natuurl. Geschied. & Physiol. 7: 314. 1840) ten-tatively to Lauraceae.Hornera was described in an article with the misleading title: Nova genera et species plantarum Javanicum, as the species numbered 22 to 27 are from Japan. Under no. 22 there is a remark: "siccatam e regius japonico accepi".Flora Malesiana gives no clue where this Japanese collection came from; no collecting localities and no collectors are mentioned by Junghuhn).According to Maximowicz (in Bentham & Hooker f., Gen. PI. 3: 188-189. 1880) the genus should not be Japanese; this wrong statement is apparently due to the fact, that Maximowicz could not attribute the genus in its circumscription to any Japanese plant.
