ORCHIDACE& (A. D. Rendle) 101 
crowded on the rhizome. Roots dense slender, branching. Leaves 
4:5-9 em. long, 1:4-2:2 cin. broad. Scape to 16 cm. long, less than 
1 mm. thick, bearing at the five nodes below the inflorescence narrow 
‘sheathing bracts 1-'5 cm. long. Raceme 5 em. long. Flowers (in 
one specimen) seventeen. Bracts 2-2'5 mm. long. Sepals 8:5 mm. 
long, the dorsal 1:5, the lateral 2 mm. broad, the broad united base 
of the latter forming a blunt chin; the margin minutely papillose. 
Petals 2 mm. long by "6 mm. broad ; lip 1°75 mm. long, barely 1 mm. 
broad. Column "5 mm. long, the slender arms *75 mm. long. Stalk 
with ovary barely 2 mm. long. Fruit 8 mm. long. 
Evidently near the Congo species B. nanum De Wild. (from the 
description) which it apparently resembles closely in habit, but differs 
in absolute and relative sizes of the sepals and petals and in the form 
of the lip. 
Bulbophyllum obanense Rendle sp. nov. Planta minor 
pseudobulbis (in vivo) anguste ellipticis suleatis diphyllis, in 
rhizomate valido rubescente distantibus, cataphyllis scariosis

angustatis obtusis ; scapo folia paullo excedente, bracteis brevibus 
specimine 5 rubescentibus e basi vaginante ovatis; spicae 
rhachide compressa floribus ochroleueis in marginibus tenuibus 
distiche ordinatis ; bracteis concavis dorso carinatis mucronulatis

paullo breviore; petalis linearibus ; labello crasso glabro trilobo, 
lobis basalibus rotunde oblongis, lobo medio late oblongo recurvo

Oban, top of Niaji Peak; n. 932; in flower Oct. 28. i 
Described from a single specimen 1:7 cm. high and a coloured 
sketch. Distance between pseudobulbs 6-7 cm., rhizome bearing 
reddish sheathing scales at the node, woody, 3 mm. thick; a tuft of 
slender filiform roots from the base of each pseudobulb. Pseudobulb 
3-4°5 em. long, 1:2 cm. thick (when fresh). Leaves 6-11 cm. long, 
1:2 to nearly 2 cm. broad. Scape 10-13 cm. long to base of spike. 
Bracts 6-7 mm. long. Spike 6 cm. long, rhachis 2-3 mm. broad. 
Flowering bracts 4 mm. long. Dorsal sepal barely exceeding 5 mm. 
long; lateral 5:75 mm. Petals 8:5 mm.; lip 2:25 mm., greatest 
breadth equal to length ; median lobe 1 mm. broad, with a raised line 
just within the margin. Column 1:3 mm. long. 
Evidently very closely allied to the Congo species, B. platirachis, 
described and figured by De Wildeman (Miss. Em. Laurent, 223, t. lv.), 
which it ré&embles in habit, but is a larger plant and differs in the 
absolute and relative length of the parts of the flower. B. obanense 
is characterised by its 3-lobed lip, but the details of the lip of 
B. platirachis are not described.
