Bulbophyllum canlaonense sp. nov. 
Cum B. halconensi comparandum videtur, a quo tamen sepalis 
differt. Rhizoma longe repens, gracile, elongatum, ad nodos 
radicans. Pseudobulbi pyriformi, 3 mm alti, in sicco rugosi, 
distantes. Folia 1 ad 3 cm longa, 4 ad 9 mm lata, elliptico- 
oblonga, acuta, coriacea, petiolata. Scapus usque ad 4.5 cm 
longus, foliis longior, 1-florus, a basi pseudobulbi vel a rhizomate 
in medio inter pseudobulbos ortus. Flores atropurpurei, usque 
ad 12 mm longi. Sepala lateralis ovato-lanceolata, acuta. Sep- 
alum superius simile. Petala 6 mm longa, 3 mm lata, elliptica, 
ad apicem rotundata, acuta. Labellum 4.5 mm longum, cordato- 
lanceolatum, acutum. Columna brevis, in medio columnae dens 
vel papilla. 
Negros, Canlaon Volcano, April 10, 1910, Elmer D. Merrill 7015. 
Epiphyte, rather abundant, altitude above sea-level 1,200 to 1,700 m, flower 
dull-purple. 
A near ally of Bulbophyllum halconense from which it differs mainly 
in the entire absence of caudate tips to the sepals (cf. Orchidaceae 3: 54, 
pi. U, fig. 3 C. c.) 
Bulbophyllum Elmer! sp. nov. 
Rhizoma repens, gracile, elongatum. Pseudobulbi pyriformes, 
rugosi, distantes, monophylli. Folia vix petiolata, lanceolata, 
acuta, breviter apiculata. Scapi filiformes, ad basim bractea 
tubular! vaginati, a basi pseudobulbi vel a rhizomate in medio 
inter pseudobulbos ortus, interdum scapi orti a pseudobulbo uno. 
Sepala lateralia triangulari-linearia, acuminata, valde acuta, 
3-nervia. Sepalum si(,perius simile. Petala elongata sepalis vix 
breviora, linearia, acuminata, longe aristata, 1-nervia. Labellum 
3-lobum, lobi laterales parvi, rotundati, lobus medius subcordatus, 
crassus, apex erectus vel recurvatus, incrassatus, ad basim lab- 
ellum Carina brevis, gnomon! solari similis. Columna brevis, 
antice utroque ad apicem processus setiformis. 
Rhizome about 1 mm thick. Pseudobulbs about 1 mm apart, 
5 mm tall. Leaves 1 to 2.5 cm long, up to 5 mm wide. Scape 
equaling the leaves in length or shorter. Lateral sepals about 
4 mm long, about 1 mm wide ; upper sepal similar to the laterals. 
Petals very slender, prolonged into a thread-like or aristate tip, 
4 mm long. Labellum 1.5 cm long, 3-lobed, cuneate at the base,
