10. B. APETALUM ; pseudobulbis angulatis diphyllis foliis zequalibus, 
scapis setaceis foliis longioribus, spica laxa pauciflora, sepalis carnosis

11. B. MICROPETALUM ; pseudobulbis angulatis diphyllis foliis lineari- 
bus emarginatis obtusis zequalibus, scapo setaceo foliis longiore, spica 
pauciflora, bracteis brevibus cucullatis, floribus subrotundis, sepalis 
acutis, petalis setaceis obsoletis, labello euneato cucullato antice re-

“Epiphyte. Fernando Po, at 4000 feet, Dec. 1860." (644) Mann. 
In general habit like B. intertextum; two minute bristles are
