Goodyerinae in the Rijksher- Going Through Barium, Several Sumatra TWO NEW ORCHID GENERA 399 X. Two orchid genera new to Sumatra (Orchidaceae) A. Schuiteman Rijksherbarium / Hortus Botanicus, POB 9514, NL-2300 RA Leiden, The Netherlands Summary of the orchid Kuhlhasseltia Species genera and Orchipedum are recorded from Sumatra for the first time. Introduction The subtribe Orchidaceae-Goodyerinae is well represented in Malesia, with about 25 genera and hundreds of species. They are almost exclusively terrestrial plants with inconspicuous flowers, usually growing in deep shade in undisturbed forests. Many seem to prefer sloping terrain with seeping water. Some have very beautiful foliage and with are occasionally (often difficulty) cultivated, being popularly known as Jewel of the Orchids, e.g. species genera Anoectochilus, Dossinia, Goodyera, Ludisia, and Macodes. The of the other either have great majority Goodyerinae uniformly greenor cryptic darkbrown foliage. Although the genera ofthe Goodyerinae are reasonably distinct, it is often necessary to analyse a flowerbefore a reliable identification can be made. As a result they are fre- quently left unidentified, or, worse, they are incorrectly referred to generaof which the name is more or less familiar, such as Anoectochilus and Goodyera. While going through the unidentified and misidentified Goodyerinae in the Rijksher- barium, several interesting discoveries were made. Two of these are discussed below. Kuhlhasseltia cf. javanica J.J. Smith Mamas River Sumatra, Aceh, Upper valley, 1400-1700m (De Wilde & De Wilde- 18264 June Duyfjes , 1979). The genus Kuhlhasseltia, although widely distributedfrom PeninsularMalaysia to New Guinea with about7 species, is rarely collected. This appears to be the first record from Sumatra. Orchipedum plantaginifolium Breda Lau Alas 200-400 Wilde Sumatra, Aceh, valley, m {De & De Wilde-Duyfjes 12759, June 1972). Vegetatively this remarkablespecies, the only one in the genus, is among the largest Goodyprinae-, it is not easily overlooked and must therefore be a very rare plant, as it has been collected only four times before: twice in Java and twice in Peninsular Malay- sia, the last time in 1938 (fide Seidenfaden& Wood, 1992).

Z. flava and Z. sakagutii and another pair of species of Rhomboda, R. moulmei- nensis and R. fanjingensis, are so similar that they are frequently misidentified.

Key words: Chinese orchids, Rhomboda, Zeuxine Introduction Zeuxine Lindley (1826: 18) and Rhomboda Lindley (1857: 181) belong to subtribe Goodyerinae (Orchidoideae; Cranichideae; Pridgeon et al. 2003a, 2003b). Zeuxine comprises about 80 species distributed in tropical and southern Africa through tropical and subtropical Asia, to New Guinea, northeastern Australia, and the southwestern Pacific islands; with 14 species occurring in China, two of them are endemic (Chen et al. 2009b). Flowers of Zeuxine species are nearly always white or green, but a few are yellow.

This article is published with open access at Springerlink.com Abstract A comprehensive study on the orchid diversity in Penang Hill, Penang, Malaysia was conducted from 2004 to 2008 with the objective to evaluate the presence of orchid species listed by Curtis (J Strait Br R Asiat Soc 25:67–173, 1894) after more than 100 years. A total of 85 species were identified during this study, of which 52 are epiphytic or lithophytic and 33 are terrestrial orchids. This study identified 57 species or 64.8% were the same as those recorded by Curtis (1894), and 78 species or 66.1% of Turner’s (Gar- dens’ Bull Singap 47(2):599–620, 1995) checklist of 118 species for the state of Penang including 18 species which were not recorded by Curtis (1894) and the current study but are actually collected from Penang Hill. A comparison table of the current findings against Curtis (1894) and Turner (1995) is provided which shows only 56 species were the same in all three studies. The preferred account for comparison was Curtis’ (1894) list as his report was specifically for the areas around Penang Island especially Penang Hill, Georgetown and Ayer Itam areas.

Raya Jakarta-Bogor Km 46, Cibinong, Bogor 2P.O. Box 8210, Cairns 487, Queensland, Australia 3Author for correspondence: [email protected] Abstract The Goodyera rubicunda complex has broad morphological variation of the floral parts. A revision of the G. rubicunda complex was conducted and three intraspecific groups were recognised; G. rubicunda var. rubicunda which is the widespread variety, G. rubicunda var. triandra, and G. rubicunda var. australis var. nov. Herein, we propose the variety G. rubicunda var. australis from Australia and Papua New Guinea as newly described. Introduction Goodyera R.Br. is classified as belonging to subfamily Orchidoideae, tribe Cranchideae, subtribe Goodyerinae (Pridgeon 2003), containing approximately 98 species that are currently recognised as belonging to the genus (www.theplantlist.org, accessed 2 Jan 2014). Schlechter (1911) classified Goodyera as part of subfamily Monandrae, division Acrotonae, subdivision Polychondreae, and group Physurinae (subtribe Goodyerinae, Dressler and Dodson 1960; Pridgeon et al. 2003). Goodyera species are characterised by their terrestrial habit, horizontal creeping stems, a rhizome about as thick as the stem, rather thick pubescent roots, leaves either in rosettes or spread laxly along the stem, a terminal, often pubescent inflorescence, and a generally pubescent, saccate labellum often with internal fleshy hair-like glands (Comber 1990; Dockrill 1992).

  • STATUS of ORCHID TAXONOMY RESEARCH in the PHILIPPINES Review
    Philippine Journal of Systematic Biology Vol. I, No. 1 (June 2007) Review STATUS OF ORCHID TAXONOMY RESEARCH IN THE PHILIPPINES Esperanza Maribel G. Agoo Biology Department, De La Salle University-Manila Orchidaceae is the largest of the monocotyledonous families in the Philip- pines. There are over 137 genera and about 998 species of orchids so far re- corded for the archipelago. This represents about 10% of the total flora of the Philippines. The Philippines ranks second to New Guinea in occurrence of en- demic species in the Malesian region. The monotypic endemic genera of orchids are Ceratocentron, Megalotus, Phragmorchis, and Schuitemania. Bogoria, Chelonistele, Lepidogyne, Omoea, Orchipedum are Malesian endemics repre- sented in the Philippines by one species each. The largest genera are Bulbophyllum (137 species), Dendrochilum (89 species), Dendrobium (85 species), Eria (54 species), Liparis (38 species), and Malaxis (33 species). Orchid collecting started in the Philippines as early as the Spanish times by Spanish missionaries like I. Mercado, G. Kamel, J. Blanco, Llanos, Fernandez- Villar, and Naves. Other notable collectors or expeditions were P. Sonnerat, T Haenke and L. Nee (Malaspina Expedition), A. von Chamisso (Romassoff), S. Perrottet (Le Rhone), H. Cuming, A. Loher, F.J.F. Meyen (Princess Louise of Prussia), C. Gaudichaude-Beaupre (La Bonite Expedition), Wilkes Expedition, and the Challenger. This was also the time when horticultural companies brought plants to Europe for trade (Mendoza, 1959). Collectors of the the Forestry Bureau in the 19th century, then the Bureau of Government Laboratories, and finally the Bureau of Science amassed a huge collection of specimens for the herbarium.

John Hayden, Botany Chair o temperate-zone plant enthusiasts, the orchid family seems more than a little strange. On the one hand, native orchids grow wild without assistance from people, they are rooted in the soil, and they survive freezing cold winter temperatures. On the other hand, the tropical or- chids that we encounter are ornamental plants, pampered by their human caregivers, cultured indoors in pots fi lled with fi r bark or other media designed to mimic the plants’ natural epiphytic habit, and, as a group, these ornamental tropical orchids have essentially zero tolerance to frost. Of course, their fl owers, fruits, and seeds defi ne them all as members of the orchid family, Orchidaceae, but from the perspective of how they actually live, and how we interact with them, native orchids and their tropical ornamental relatives seem utterly, profoundly, different.
