| Pholidota kinabaluensis is transferred to the new monotypic genus Entomophobia. Coelogyne phaiostele, C. ridleyana, and Pholidota triloba are identical and transferred to the new genus Geesinkorchis, that also comprises the new species G. alaticallosa. The monotypic genus Sigmatochilus is reduced to Chelonistele, in which C. dentifera and C. lurida var. grandiflora are described as new. Chelonistele crassifolia is regarded as a variety of C. sulphurea. |

| Section Moniliformes Carr of the orchid genus Coelogyne is revised using morphological and molecular data. Twelve species are recognised, including two new ones (C. chanii and C. renae). and a dubious one (C. crassiloba). A combined analysis of morphological characters, and sequences of the nrDNA ITS region, matK gene, trnT-trnL intergenic spacer, trnL intron and trnL-trnF intergenic spacer supports the monophyly of the section as here recognised. Persistence of the rhizome scales, shape of the margin of the leaves, inflorescence type, shape of the rachis, its nodes and pedicel scars, indument of the floral bracts, lip size and depth of the sinus of the lateral lobes of the hypochile seem to be phylogenetically informative characters. Shape of the leaf... |

| This article presents a taxonomic revision of the genus Pholidota (9 sections, 29 species, 7 varieties). Acanthoglossum is reduced to section level, section Repentes is newly described. One species (P. mediocris) is described new. 3 species names are reduced to variety level (P. camelostalix var. vaginata, P. carnea var. parviflora, P. carnea var. pumila). 28 species names and 8 variety names are for the first time reduced to synonymy. Keys are provided to the sections, species and varieties. Synonymy, description, distribution, habitat notes, colour descriptions and detailed illustrations are given for each species and variety. |

| In 1979 a combined Indonesian-Dutch expedition, sponsored by WOTRO, was held in Sulawesi, Indonesia. In addition to herbarium material, a large number of living orchids was collected. The living plants were distributed to the Kebun Raya, Bogor, the Hortus Botanicus, Leiden, and the Hortus Botanicus, G.U., Amsterdam. Among the specimens which flowered in Leiden, two different species appeared to belong to the genus Bracisepalum. This genus was hitherto only known from the type collection of B. selebicum. Additional herbarium material of this species was collected by Van Balgooy in the field. This article is the first in a series of treatments for Flora Malesiana of genera belonging to the subtribe Coelogyninae, by the first author. The next revision will... |

| The revision of the genus Chelonistele in Orchid Monographs 1 (1986) 23-40 lists 11 species and 4 variations. All occur in Borneo, which is evidently the centre of speciation of this genus; only Chelonistele sulphurea var. sulphurea occurs in addition in Java, Sumatra and the Malay Peninsula. During joint fieldwork in 1991 with staff of the Sarawak Herbarium in the Hose Mountains, Sarawak, the present author collected herbarium and live specimens of many orchids. Among the live orchids were quite a number of Chelonistele species from different habitats. Fifteen of these, belonging to six species, flowered in the Leiden Hortus Botanicus. Two are common and are well known from many herbarium specimens: C. sulphurea var. sulphurea and C. amplissima. Three... |

| This paper embraces a full taxonomic revision of the tribe Apostasieae. The introduction is followed by an ample discussion of the taxonomic position of the Apostasieae and the affinities within the tribe. The tribes Apostasieae and Cypripedieae are regarded as forming together the subfamily Cypripedioideae of the Orchidaceae. Notes are given on the morphology and an evaluation is given on systematic characters and their value for specific delimitation. Two characters were formerly underestimated in Neuwiedia, notably the indument (maximal length of the glandless hairs) and the structure (texture) of the pericarp. The systematic treatment provides descriptions of the tribe, the genera, and the species, keys for identification, full synonymy, typification,... |

| This article contains a taxonomic revision of Coelogyne section Tomentosae (24 species). Five species (C. acutilabium, C. bruneiensis, C. echinolabium, C. latiloba, C. velulina) are newly described; three other species are allotted for the first time to this section (C. buennemeyeri, C. distans, C. rupicola). One species, formerly included in section Tomentosae, is excluded (C. veitchii). Six species are here reduced to synonymy. A key to the species is provided. Synonymy, description, distribution, habitat notes, colour descriptions and detailed illustrations are given for the section and all its species. |

| This volume is the continuation of ‘The Concise Flora of Singapore: Gymnosperms and Dicotyledons’, published in 1990. All native and naturalised Singapore seed plants are covered by these two volumes, as well as some of the commonly cultivated ones. This volume covers 34 families with approximately 750 species. Keys to the families and genera are presented. In Orchidaceae separate keys to the subfamilies and in some of these to the tribes and genera are presented. Selected species are keyed out in Orchidaceae, Cyperaceae, and Gramineae. In the last family a separate key to the bamboos is given. No reference to page numbers is given in the keys. In general, the characters used for identification are adequate and not too technical. |

| This article contains a taxonomic revision of four orchid genera of the subtribe Collabiinae: Chrysoglossum (4 species), Collabium (11 species), Diglyphosa (2 species), and Pilophyllum (1 species). Three species are described as new: Chrysoglossum ensigerum, Collabium acuticalcar and Collabium carinatum. Chrysoglossum halbergii, Ch. maculatum, Ch. gibbsiae, and Ch. cyrtopetalum are reduced to Chrysoglossum ornatum. Diglyphosa macrophyllum, D. celebica and D. elmeri are reduced to Diglyphosa latifolia. Keys to the genera and species are given. Synonymy, descriptions, colour notes, distribution, habitat notes, and detailed illustrations are given for the genera and species. |

| Section Verrucosae Pfitzer & Kraenzl. of the genus Coelogyne Lindl. is revised using morphological and molecular data. Eight species are recognized, including two new ones ( C. marthae and C. verrucosa). One name is reduced to synonymy. Four species formerly included by several authors in sect. Verrucosae (C. brachyptera, C. papillosa, C. parishii and C. virescens) are excluded. A total evidence analysis of morphological characters and ITS and matK sequence data supports the monophyly of the section as here recognized. Coelogyne virescens (sect. Brachypterae) is identified as nearest neighbour to the species of sect. Verrucosae. The number of sterile bracts on the rhachis and the shape of the ornamentation on the epichile appear to be phylogenetically... |
