NEW OR NOTEWORTHY ORCHIDS 
dendron has larger flowers, subtrilobed lip and a prominent 
tooth at the apex of the column. E. rugosum, which will, 
perhaps, prove to be inseparable from this variable species, 
appears to have a different lip which is ecallose, and sharper 
sepals and petals.

Epidendrum Sanchoi Ames var. exasperatumA. SzS. 
var. nov. A specie floribus paulo minoribus, sepalis ellipticis 
vel ovalis, acutis vel obtusis (non lanceolatis acuminatis), 
petalis saepe leviter retusis, atque labelli lamina breviore 
columnae subaequali differt. 
This variety differs from the species only in certain 
well-marked floral characteristics. Flowers somewhat smaller 
than in the typical form. Lateral sepals obliquely ovate- 
elliptic, acute or obtuse, about 4.5-5.5 mm. long, about 2-3 
mm. wide near the middle. Dorsal sepal oblong-elliptic or 
obovate-oblong, usually obtuse, 4.1-5.5 mm. long, 2-2.5 
mm. wide. Petals obliquely elliptic-linear, linear or oblan- 
ceolate-linear, 4-4.9 mm. long, 1-1.35 mm. wide, obtuse or
