NOTES ON PHILIPPINE ORCHIDS, III. 51 
to 3 dm long, 9 em wide. Raceme 5-flowered, bracts cymbiform up to 3 
cm long. Sepals about 3 cm long. Petals rhomboidal, obtuse. Label- 
lum 3-lobed, lateral lobes dolabriform, about 5 mm long, 5 mm wide, 
middle lobe obtuse, about 7 mm long. Disk lamellate, lamellae 5, fleshy, 
prominent. 
This peculiar species, which was originally introduced from the Philippine Is- 
lands, and described by Linden and Cogniaux in “Le Journal des Orchidées” in 
1896, has just come to hand from Luzon, where it was collected by Father M. 
Vanoverbergh. The flowers are yellowish with dark spots and the labellum is 
nearly white. My knowledge of the species, unfortunately. is based on the 
original description and not on an examination of the type material. I have 
seen no other specimen of Acanthophippium from the Philippines. 
232. PACHYSTOMA Bl. 
Pachystoma pubescens Bl. Bijdr. 376. 
Pachychilus pubescens Bl. Mus. Bot. Lugd. Bat. 2: 173. 
I refer to this species several specimens recently collected in Luzon. They 
agree with the material figured in detail by Blume and with a Javan plant 
preserved in the herbarium of the British Museum of Natural History, collected 
by Horsfield.
