A synopsis of Dryadorchis Schltr. (Orchidaceae) Naturalis
Schuiteman, A.; Christenson, E.A..
Contrary to published descriptions, the poorly known New Guinea genus Dryadorchis Schltr. neither has a footless column, nor an immobile labellum. The merger of Dryadorchis with Thrixspermum Lour., as proposed by Clements, Wallace, and Jones, is not justified. Chamaeanthus singularis J.J. Sm. and Sarcochilus huliorum Schuit. are transferred to Dryadorchis. A key to the four known species is given.

Biogeography of Malesian Orchidaceae Naturalis
Schuiteman, A..
The Orchidaceae outnumber by far any other plant family in Malesia. At present, however, an accurate estimate of the number of Malesian orchid species is difficult to make. Subtracting the number of established synonyms from the number of names attributed to Malesian orchid species results in the staggering figure of 6414 species, with a retention ratio (ratio of ‘accepted’ species to heterotypic names) of 0.74. This is undoubtedly a gross overestimate, as most of the 209 Malesian orchid genera have never been revised over their entire range. Extrapolating from available revisions to estimate a more realistic retention ratio is problematic due to the small number of modern revisions and the different nature of the groups treated. If we look for comparison...

Devogelia (Orchidaceae), a new genus from the Moluccas and New Guinea Naturalis
Schuiteman, A..
The new orchid genus Devogelia from the Moluccas and New Guinea is described and illustrated. Its possible affinities are discussed and it is tentatively concluded that Devogelia belongs either to the tribe Cymbidieae or to the Malaxideae. So far a single species, here described as D. intonsa Schuit., is known, which occurs as a locally abundant terrestrial in lower montane forest.

Key to the genera of Orchidaceae of New Guinea Naturalis
Schuiteman, A..
With roughly 2300 known species in 133 genera (see Appendix), New Guinea is the richest area in the palaeotropics as far as orchids are concerned. Up to the present the only useful key with which orchids from New Guinea can be identified to genus level is that published by J.J. Smith in 1934. This key is now obsolete in several respects because of changes in nomenclature and in taxonomic views. Besides, Smith’s key is not always very practical; frequent use is made of characters which are difficult to evaluate in preserved material or which easily may be misunderstood. Yet, many orchid genera can be recognized at a glance, a fact which is not at all obvious from most keys that I have seen.

New combinations in Cadetia and Pantlingia (Orchidaceae) Naturalis
Schuiteman, A..
The following species, described in Dendrobium but belonging to Cadetia, have not yet been formally transferred: Cadetia citrina (Ridley) Schuiteman, comb. nov. Dendrobium citrinum Ridley, Trans. Linn. Soc. London, ser. 2, 9 (1916) 175. Dendrobium fluctuosum J.J. Sm., Bot. Jahrb. 66 (1934) 186, syn. nov. — Cadetia fluctuosa (J.J. Sm.) P.F. Hunt, Kew Bull. 26 (1971) 179, syn. nov. Note – Cadetia citrina is a distinctive, large-flowered species, related to C. cyclopensis (J.J. Sm.) Schltr., but with relatively much shorter, elliptic petals and broadly rounded side-lobes to the lip. More than half a dozen collections of C. citrina were studied, including the types of Dendrobium fluctuosum and D. citrinum. They are quite constant morphologically, differing...

New names and combinations in Orchidaceae from the Philippines and New Guinea Naturalis
Schuiteman, A.; Vogel, E.F. de.
New names and combinations are proposed for species of the orchid genera Bulbophyllum, Dendrobium, Flickingeria, Glomera, Octarrhena and Trichotosia. The genera Ischnocentrum and Sepalosiphon are synonymised with Glomera, while Chitonanthera is synonymised with Octarrhena.

Notes on Goodyerinae (Orchidaceae) — I Naturalis
Schuiteman, A..
Goodyera subregularis (Rchb. f.) Schltr. from New Caledonia and Vanuatu is transferred to Anoectochilus. A non-peloric Anoectochilus, possibly the normal form of A. papuanus (Schltr.) Kittr., is recorded from New Guinea for the first time. Platylepis bombus J.J. Sm. and P. tidorensis J.J. Sm. are transferred to Moerenhoutia. The genus Tubilabium J.J. Sm. is reduced to Myrmechis Blume and the two species of the former are transferred. Cheirostylis quadrilobata Schltr. and C. chalmersii (Schltr.) Schltr. are also transferred to Myrmechis. The genus Myrmechis was not previously recorded from Sulawesi and New Guinea. Papuaea reticulata Schltr. is newly recorded from Irian Jaya; this monotypic genus is here illustrated for the first time. Odontochilus...

Review Naturalis
Schuiteman, A..
The first edition of this work appeared in a single volume in 1969. Now, about a quarter of a century later, so many additional species had to be included, that two volumes are needed. Most of the additions are new species described since 1969, partly as a result of the splitting tendencies of some recent Australian botanists, of which Dockrill is highly critical. Each species is described in detail and illustrated with a full-page line drawing. While perhaps not of professional quality, the drawings are sufficiently clear and accurate to make the task of identifying almost any tropical Australian orchid a light one. In addition, all genera and species are keyed out. The distribution within Australia is usually given in considerable detail, but for those...

Review Naturalis
Schuiteman, A..
Three years after publication of volume 2, which was entirely devoted to Bulbophyllum (by J.J. Vermeulen), volume 1 of what should become a complete iconography of the Orchids of Borneo has appeared. Each volume is projected to contain a hundred species, which means that eventually fifteen volumes will line up on our shelves. If the pace of production is not increased, most of us will be retired or dead by then. I really hope to live to see the completion of this series, because it is magnificent! It invites comparison with the legendary series ‘Venezuelan Orchids Illustrated’ by Dunsterville & Garay, both in format and in the quality of the illustrations. The text is much better, however, giving not only descriptions, but also elaborate notes on...

Review Naturalis
Schuiteman, A..
The number of orchid species in New Guinea is not easily estimated; there are many large, poorly studied genera, of which scores of undescribed species as well as many synonyms are waiting to be discovered. There may well be about 2500 species in all: almost double the size of the entire phanerogamous flora of the Netherlands! Only few recent publications (apart from taxonomic revisions of individual genera) are available to those who want to learn more about them. The most important is still the translation into English of Schlechter‘s 1914 classic ‘Die Orchidaceen von Deutsch-Neu-Guinea’, which appeared in 1982 as ‘The Orchidaceae of German New Guinea’. Unfortunately the Latin descriptions were not translated, and Schlechter’s illustrations consist...

Review Naturalis
Schuiteman, A..
As stated in the preface, this book is intended as a textbook on orchid biology. Fifteen chapters treat a diverse array of topics, from physiology to ethnobotany. In spite of its title, Fundamentals of Orchid Biology contains much general information that is only indirectly related to the purported subject matter. The chapter on cytology, for example, contains little which cannot be found in any undergraduate textbook on cell biology. More than one page in this chapter is devoted to the microscope used by Robert Brown, about which we learn that “it was made by the English barometers manufacturer Robert Banks (who also spelled his name Bancks) before 1820, and its stage is engraved with the maker’s name and address –Banks 441 Strand London.” I quote this as...

Review Naturalis
Schuiteman, A..
Judging from the title this would be a book for a distinctly limited audience. After all, only very few of the more than 430 South African orchid species are in general cultivation. For two reasons that judgement would be wrong. First, many South African orchids deserve to be much more widely cultivated. This book may be considered an excellent promotion for these beautiful but neglected species. Second, this book could well be described as an up-to-date guide to orchid growing, where the examples happen to be South African species. Especially valuable is the detailed information on cultivating terrestrial species. These are generally much more difficult to grow than the epiphytic ones, and most of the advice given here applies just as well to Australian...

Revision of Agrostophyllum section Appendiculopsis (Orchidaceae), with notes on the systematics of Agrostophyllum Naturalis
Schuiteman, A..
Section Appendiculopsis of the orchid genus Agrostophyllum is revised. Six taxa are recognized: Agrostophyllum elongatum, A. laterale, A. stipulatum subsp. stipulation and subsp. bicuspidatum, A. sumatranum and 1 A. trifidum. The status of a seventh taxon, A. ley tense, is uncertain. No new species are described here. Agrostophyllum celebicum Schltr. is reduced to A. stipulatum subsp. stipulatum, Poaephyllum hansenii J.J. Wood is reduced to A. laterale. The latter appears to be a strict rheophyte. All species are described and illustrated, and their phylogeny and ecology are discussed. The infrageneric classification and the systematic position of Agrostophyllum are reviewed.

Sarcochilus huliorum (Orchidaceae), a new species from Papua New Guinea Naturalis
Schuiteman, A..
Sarcochilus huliorum Schuiteman from Papua New Guinea is described and illustrated. A very distinct species, it is probably related to S. singularis (J.J. Smith) J.J. Smith. These two species, having ephemeral flowers, four pollinia and a relatively short column-foot, are more or less intermediate between the genera Sarcochilus, Pteroceras and Brachypeza.
