Distrib. — Larut Hills, Perak.

Distrib. — Pei-ik, Selaiigor and Paliaug mountains. 



110. BULBOPHYLLUM (§ MoNANTHA PAKVa) ARANIFERUM, Sp. nOV. 



Rhizome long, creeping, with abundant fairly thick roots, 

 almost entirely covered above with adnate pseudobulbs. 

 Pseudobulbs oblong, horizontally appressed to the slender 

 rhizome, the short apices only free and upcurved, 1 cm. 

 long, 0.3 cm. thick (when dry). Leaf elliptic lanceolate, 

 apex shortly acute, base narrowed to the petiole, 5 cm. 

 long (including the petiole) 0.8 cm. wide. Scape, rising at 

 the base of the pseudobulb slender, one-flowered 5 cm. long 

 with a lanceolate acuminate persistent sheathing bi'act 0.5 

 cm. long. Pedicel and ovary 2 cm. long. Sepals subequal, 

 linear acuminate caudate, 4-nerved, the two central nerves 

 thicker than the two outer ones, 3.2 cm. long by 0.5 cm. 

 wide at the base. Petals linear obtuse 0.5 cm. long, all 

 apparently whitish. Lip tongue-shaped acuminate, tip 

 blunt, oi-ange coloured, base cordate with sides thin rounded, 

 apex fleshy grooved down the centre, 0.6 cm. long. Column 

 short with subulate stelidia, foot narrow at first horizontal 

 then rather abruptly up-cui^ved. Anther rather large with 

 a short distinct filament, pollinia oval elliptic. 



I have only seen one flower. 



This is undoubtedly allied to B. striatellum, Ridley, a native of 

 the mangrove swamps in Singapore. It resembles B. 

 montense, Ridley, and B. catenarium in the peculiar arrange- 

 ment and form of the pseudobulbs. The long narrow 

 caudate sepals are peculiar in this section. 



111. BuLBOPHTLLUM CAPiTATUM, Lindley. 



Apparently abundant. Common on all our mountain ranges 

 from 2,000 to 6,000 feet. Also occurring in Boi-neo and Java. 



112. BuLBOPHYLLUM SELANGORENSE, SJ). nOV. 



Rhizome long, branched, stout, woody over 0.5 cm. in diameter, 

 densely covered with roots, pseudobulbs absent. Leaf 

 oblanceolate coriaceous, apex blunt, base long, narrowed to 

 the petiole, 18 cm. long, 4 cm. wide, petiole 8 cm. long. 

 Scape about 30 cm. long, the basal half nude except for two 

 or three sheathing bracts, the uppermost one f oliaceous with 

 a lanceolate acute limb, 5 cm. long. Raceme 15 cm. long, 

 floAvers rather scattered. Bracts lanceolate, 0.3 cm. long, 

 shorter than the pedicel. Sepals lanceolate ovate acute, 

 0.3 cm. long, the lower pair connate at the base forming 

 a rounded gibbous sac. Petals neai'ly as long, linear oblong
