4 w 
the lower half ciliated or serrulated. Labellum diminutive, Ungu- 
late, about 2 mm long, obtuse, fleshy, bicristate. 
POLILLO, C. B. Robinson, Bur, Sci. 9077, August 9, 1909, growing on 
Heritisra littoralis, buds deep-yellow, flowers somewhat paler. 
The plants figured in the "Botanical Magazine" have longer leaves, and 
larger pseudobulbs than the specimens from Polillo. 
Bulbophyllum RamoslI sp. nov. 
Folia oblonga, ad apicem rotundata. Scapus gracilis, brae- 
teis tubularibus. Flores albi. Bracteae infiorescentiae lineares. 
Sepala lateralia triangularia, caudata. Sepalum superius conca- 
vum, lanceolatum, caudatum. Petala lineari-lanceolata, acuta, 
1-nervia, Labellum lingulatum, ciliatum. Columna bifurcata. 
Plant small, to the tip of the leaf not exceeding 1 dm. Rhizome 
comparatively slender, rooting freely. Pseudobulbs wanting, 
the leaves arising directly from the creeping rhizome. Leaves 
rigid, leathery, oblong, rounded at the tip, tapering gradually 
at the base, lamina up to 7 cm long, 11 mm wide, with a promi- 
nent mid-nerve. Scape weak, slender, longer than the leaves, 
up to 8 cm long, with several tubular bracts about 5 mm long 
below the raceme. Raceme lax, about 7-flowered. Flowers 
white. Bracts of the raceme linear, exceeding the pedicellate 
ovary, about 4 mm long. Lateral sepals triangular, prolonged 
into a slender caudate tip, triangular base about 3 mm long, 
caudate tip 5 mm long. Upper sepal shorter than the laterals, 
concave, lanceolate, caudate-tipped, 7 mm long. Petals linear- 
lanceolate, acute, 1-nerved, about 3 mm long. Labellum Ungu- 
late, strongly bent at the middle, apical half nearly 2 mm long, 
oblong, rounded at the tip, margin coarsely hairy, basal half 
sulcate, when spread out orbicular. Column at the tip bifurcate.

This is a smaller species than Bulbophyllujn adenopetalum Lindl., to 
which it is closely allied. The flowers resemble the sketch of B. adenopet- 
alum, by Lindley, preserved at Kew. The leaves are much shorter than in 
Lindley's material and much broader in relation to their length. Both species 
are different from B. dasypetalum Rolfe, in their caudat«-tipped lateral 
sepals, and ciliolate lips. B. braccatum, a Philippine species described by 
Reichenbach f., belongs in the same group. Of this species, unfortunately, 
I have seen no material; no type is designated by its author. The descrip- 
tion is vague, no details regarding the foliage being given, and, in view of 
the fact that there is a group of species in the Philippines closely allied with 
B, adenopetalum and B. dasypetalum, wholly inadequate for purpose of 
identification and useless for comparative studies.
