Bulbophyllum Vanoverberghii belongs to a small group of Philippine 
species of which B. dasypetalum Rolfe and B. adenopetalum Lindley are 
representatives. It appears to be closely allied to B. braccatum Reichb. f. 
a species which is known to me only through the brief and incomplete 
description published by Reichenbach f.* Up to the present time I have 
been unable to assign with certainty any Philippine specimens to B. 
braccatum. B. Vanoverberghii is distinguishable from B. dasypetalum 
Rolfe chiefly by the very dissimilar foliage. The flowers of these species 
are very similar in detail. 
Bulbophyllum zambalense sp. nov. 
Rhizoma elongatum. Pseudobulbi nulli vel minuti. Folia 
oblanceolata, coriacea, petiolata. Scapus folio longitudine fere 
aequalis vel longior, ad basim bracteis imbricatis. Racemus 
laxus. Flores flavidi. Sepala lateralia triangulari-lanceolata, 
subcaudata, acuta. Sepaluwm superius lanceolatum, acutum, con- 
cavum. Petala spathulata, obtusa, l-nervia. Labellum lingu- 
latum, 3-nervium. Columna breviter bicuspidata. 
Rhizome creeping, elongated, bearing at intervals of 3 to 5 
em, coriaceous, oblanceolate leaves. Pseudobylbs reduced to 
small thickenings on the rhizome. Leaves petiolate, lamina 
about 5 cm long, 6 mm wide. Petiole about 1 em long. Scape 
equaling or somewhat longer than the leaves, clothed at the 
base by several, scarious, imbricating bracts. Raceme loosely 
few-flowered, bracts 2 mm long, linear-lanceolate, acute. Flowers
