The specific name is in allusion to the bell-shaped 
flower. 
Mawillaria campanulata differs trom Camaridium lat- 
ifolum Schltr. in having the pseudobulbs surrounded by 
leaf-bearing sheaths and in having a much smaller lip 
which lacks the central beard on the disc. It differs from 
C.costaricense Schltr. in bearing pseudobulbs and in hav- 
ing a lip without the conspicuous basal band of papillae.

Plant slender with a much thickened woody rhizome 
which produces numerous stout fibrous roots and, in our 
specimens, terminates in a pseudobulb. Pseudobulb cy- 
lindrie to narrowly ellipsoid, about 3 cm. long, strongly 
complanate and longitudinally striate-sulcate in the dried 
specimen, monophyllous, distichously surrounded by two 
or three pairs of conduplicate leaf-sheaths of which the 
largest (inner) sheath is 9 cm. long. Leaves linear-ligu- 
late, about 14-23.5 em. long, 10-12 mm. wide, often 
conduplicate throughout, unequally bilobed and apicu- 
late at the rounded apex, chartaceous in the dried speci-
