DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 235 
Epiphytic ; sepals and petals veined orange yellow; at 11,000 feet (Haviland, 1099). 
This species with the next, belongs to a small series of very small plants characterized 
by the moniliform rhizome, every node of which normally produces a single leaf, and at 
intervals throws up a slender pedicel terminated by a single flower, the lateral sepals of 
which are longer than the upper one. 
Bulbophyllum striatellum, Ridl., belonging to the same section, has been unfortunately 
somewhat confused with B. concinnum, Hook. fil., Ic. Pl. t. 2038, as by an accident the 
stelidia in the diagram of its fertilization (Annals of Botany, iv. no. xv. pl. xxii.) have been 
represented too long. The shape of the petals alone would show that the two plants are 
utterly distinct. B. concinnum, Hook., belongs to the capitate group with distinct 
pseudobulbs (B. leptanthum, Hook., &c.). B. striatellum resembles this group in its 
vegetative organs, but is distinct in its single flower with oblong caudate sepals.

Bractea minuta ovata. Pedicellus longus capillaris. Flos parvus, late expansus. 
Sepalum posticum lanceolatum, obtusum, lateralia latiora, triente longiora, auran- 
tiaca, rubro-striata. Petala lanceolata, trientem sepali postici :equantia, flava, linea

longiuscula, pede longo, apice sursum curvato, libero, roseo. Anthera depressa, 
margine integro, papillosa. Stelidia longa, suberecta, dentiformia, acuminata, acuta. 
Amongst wet mosses on shrubs and trees, alt. 6500 feet (Haviland, 1164). 
Distribution: Malay Peninsula, on Mt. Bukit Hitam in the district of Selangor, at 
2000 feet (Kelsall); in mangrove jungle at Kranji near Singapore. 
This curious little species seems to have a wide distribution. I am quite unable to 
distinguish between the Kinabalu plant and that of the Singapore mangrove swamps. 
It is very abundant in the latter locality, but seldom flowers.

lanceolata, 24 poll. longa, 2 poll. lata, petiolis ł poll. longis canaliculatis. Scapi 
foliis approximati, 5 poll. longi, validi, basi vaginati, superne laxe racemosi. Flores

quam pedicelli longiores. Sepalum posticum lanceolatum, acutum, lateralia sub- 
similia, inferne prolongata, } poll. longa. Petala circiter dimidium sepali zequantia, 
oblonga, uninervia. Labellum linguiforme, carnosum, obtusum, marginibus incras- 
satis, canaliculo mediano, haud stipitatum. Columna pede recto, stelidiis triangu- 
laribus lanceolatis, acuminatis.

A stout but not very large plant, with larger flowers than in most species of the section.
