Fruit strongly laterally compressed, transversely oblong-elliptic, 9—10 mm wide, 4—5 mm high, 2—3 mm thick, pubescent, strongly nerved, with persistent calyx, lobes, dehiscing by transverse slit on top; seeds numerous, subglobose, angular, strongly ridged, ± 0.5 mm diam., brown- ish red. This species differs from 0. trichoca/rpos Bl. in bracts being conspi- cuous, linear-lanceolate, up to 4 mm long, persistent; calyx lobes linear- lanceolate up to 5 mm long; anthers longer, up to 3 mm long; style longer, up to 7.5 m long. The presence of dimorphous stamens and heterostyly is unusual in the genus. A review of different floras indicate that this has not been reported so far in Ophiorrhiza, even though certain other genera in Rubiaceae exhibit this feature.

PETERSEN Department of Botany, University of Tennessee, Knoxville, TN, USA 37916 A B S T R A C T i Type specimens of Javanese clavarias described by van Overeem — i.e. Clavaria depokensis. Clavaria luteo-tenerrima, Clavaria sanguineo-acuta and Clavulinopsis sulcata — are extant and well preserved in Herbarium Bogoriense. These are reexamined and reassigned to their respective genera and infrageneric complexes. ABSTRAK Spesimen tipe jenis-jenis Clavariaceae yang dipertelakan van Overeem dari Jawa —• yaitu Clavaria depokensis, Clavaria luteo-tenerrima, Clavaria sanguineo-acuta dan Clavulinopsis sulcata — masih ada dan disimpan di Herbarium Bogoriense. Spesimen ini diperiksa kembali dan ditunjukkan marga dan bagian marga yang layak menampungnya. Although not many, the taxa proposed and illustrated by van Overeem (1923a, b, c) have been important to an understanding of tropical clava- rioid fungal relationships. In the only modern works to deal with these taxa (Corner 1950, 1970), they were disposed of equivocally for the types had not been examined, although van Overeem's descriptions and plates were extremely accurate for their day. A recent very brief visit to the Herbarium Bogoriense allowed me to examine the type specimens con- cerned and therefore to assign them accurately to genera and to infra- generic complexes. It is to that end that this paper offered. The following items of reliquiae support these specimens: 1) all specimens include fruit bodies fixed in liquid and in excellent condition for analysis; 2) an empty, accessioned packet usually accompanies the specimens in liquid, often bearing collection data not included on the fixed specimen; 3) in one instance dried fruit bodies are in a packet separate from the material in liquid; 4) published illustrations (van Overeem 1923b, c) of fruit bodies and microscopic characters were apparently consistently made from type specimens; and 5) the original — 4 1 5 — CONTENTS Page Hsu AN KENG.
