LUZON, Benguet Subprovince, Pauai, June, 1909, R. C. McGregor, Bur. 
Sci. 8322, altitude above sea-level about 2,100 meters; same locality, Elmer 
D. Merrill 6624, May, 1909, epiphyte in mossy forest, “flowers dull-red,” 
altitude 2,250 m above sea-level. 
B. MacGregorii is nearly allied to B. mindorense and to the Bornean 
species, B. corticicola, recently described by Doctor Schlechter. From 
the former it differs in the sepals, petals and lip, and from the latter 
it is readily distinguishable by its 3-nerved sepals, B. corticicola having 
5-nerved sepals in the specimens I have examined. 
Bulbophyllum profusum sp. nov. 
Rhizoma ramosum, elongatum, diffusum, bracteis imbricatis, 
arcte vaginantibus, dense vestitum; scapis e vaginis rhizomatis 
a pseudobulbis longe remotis erumpentibus. Pseudobulbi par- 
vuli, cylindracei, in sicco rugosi. Foliwm coriaceum, elliptico- 
oblongum, breviter petiolatum. Scapus abbreviatus, uniflorus. 
Flores flavidi, sub florum solitarium bractea infundibuliformis. 
Sepala lateralia elongata, caudata, lineari-triangularia, 3-nervia, 
glabra. Sepalum dorsale simile. Petala elliptica vel ovata, 
*In dried specimens the flowers are yellowish or orange-yellow. 
McGregor made no remarks regarding the flowers of his specimens. Mer- 
rill describes the flowers of his specimen as dull-red.
