Abstract

SADILI, A., KARTAWINATA, K., KARTONEGORO, A., SOEDJITO, H. & SUMADIJAYA, A. 2009. Structure and composition of subalpine summit habitats on Mt. Gede-Pangrango complex, Cibodas Biosphere Reserve, West Java, Indonesia. Reinwardtia  12 (5): 391–404.  We undertook a phytosociological analysis of the subalpine herbaceous and shrubby vegetation at the Mandalawangi and Suryakencana meadows and the scrub at the Crater Side at the tops of Mt. Gede and Mt. Pangrango in the Cibodas Biosphere Reserve. We recorded 30 species of 18 families of saplings, shrubs, seedlings and herbs in 78 quadrats with a total area of 7,800 m2. Anaphalis javanica, a woody tall herb and long-lived pioneer was the dominant species in the sapling and shrub stratum, while Isachne pangerangensis, Tripogon exiguus and Carex verticillata were prevalent in the seedling and herb stratum at Mandalawangi and Suryakencana. Stunted shrub is Vaccinium varingaeifolium, dominant in the Crater Side scrub. Based on the importance values, the Mandalawangi meadow may be designated as the Anaphalis javanica-Isachne pangerangensis community type, the Suryakencana meadow as Anaphalis javanica-Tripogon exiguus community type and the Crater Side scrub as Vaccinium varingiaefolium-Seliguea feei community type. The similarity indices between Mandalawangi and Suryakencana community types were very high (>75 %) while those between the Crater Side and Mandalawangi and the Crater Side and Suryakencana were very low (<10 %). Poor soil conditions and fire seem responsible for the perpetual existence of A. javanica.

Abstract

The genus Rhynchoglossum in Malesia has been revised. Five species are included: R. borneense, R. capsulare, R. klugioides, R. obliquum and R. spumosum. Rhynchoglossum obliquum is a widespread and common species while the other four are endemic to Malesia. Morphological descriptions, nomenclature, distribution, ecological information and notes are provided for all species. An identification key and a list of examined specimens are included.

Abstract

KARTONEGORO, A. & VELDKAMP, J.F. 2010. A revision of Dissochaeta (Melastomataceae) in Java. Reinwardtia  13(2): 125-145. - There are 12 species of Dissochaeta (Melastomataceae) in Java, Indonesia: D. bakhuizenii, D. bracteata, D. decipiens, D. fallax, D. gracilis, D. inappendiculata, D. intermedia, D. leprosa, D. monticola, D. reticulata, D. sagittata and D. vacillans. Diplectria and Macrolenes are regarded as separate genera and species traditionally classified within the latter have not been included. Dissochaeta leprosa, D. reticulata, and D. sagittata are reinstated as species. Dissochaeta gracilis is the most common species of Dissochaeta and D. bracteata is the rarest one. There are no endemics for the island. Each taxon is provided with literature references, synonymy, morphological descriptions, distribution, ecological habitat, collectors notes, and notes. An identification key and a list of collections seen are included.

Abstract

Field exploration of the flora of the Mekongga Mountainous area of Southeast Sulawesi was conducted from 2009 to 2011. Herbarium specimens collected during this exploration and additional collections from Herbarium Bogoriense (BO) included 21 species in nine genera of the family Gesneriaceae. These comprise one species of Aeschynanthus, four species of Agalmyla, one species of Codonoboea, seven species of Cyrtandra, one species of Epithema, three species of Monophyllaea, two species of Rhynchoglossum, one species of Rhynchotechum and one species of Stauranthera. Twelve of these species are consider-ed endemic to Sulawesi while the rest are known to occur on neighbouring islands or are more widely distributed. Monophyllaea merrilliana, previously known only from the Philippine Islands and Borneo, is newly recorded for Sulawesi. A new species of Cyrtandra collected in the Mekongga area, C. widjajae, which resembles C. gorontaloensis from North Sulawesi but differs in having shorter pedicels and curved rather than straight fruits, is described.

Abstract

VELDKAMP, J. F. & KARTONEGORO, A. 2017. New species of Catanthera and Medinilla (Melastomataceae) from Halmahera, Indonesia and a new name for a Medinilla from Madagascar. Reinwardtia 16(1): 25 - 30. - One new species of Catanthera and four of Medinilla (Melastomataceae) from Halmahera, Moluccas, Indonesia, are described. One also occurs in Morotai. A new name was needed for M. intermedia H. Perrier (1932), non Blume (1831), from Madagascar.Â
