that can be sustained since the species was discovered 
during the second Lorentz Expedition to New Guinea, 
was afterwards in cultivation in the Buitenzorg Botanic 
Garden, and was there adequately described as B. macro- 
bulbum by Mr. J. J. Smith. When publishing this 
account, Mr. Smith referred the species to the section 
Sestochilos, but it has since been treated by Mr. Schlechter, 
who met with the plant again in North-eastern New 
Guinea, as the type of a distinct section, Macrobulbum. 
The species is remarkable for its very glaucous leaves, 
a character wherein it agrees with the allied B. Fletcher- 
ianum, figured at t. 8600 of this work as Cirrhopetalum 
Fletcherianum, Rolfe. The individual flowers bear some 
resemblance to those of Cymbidium Huttonii, Lindl, 
figured in this magazine at t. 5676. In cultivation it 
calls for the tropical treatment suitable for other species 
of the genus. 
Description.—Herb, epiphytic, glaucous; pseudobulbs clustered, ovoid, 
stout, bluntly angled, 2-3 in. long, 14-2} in. wide, dull olive-green with pale
