The species here described has many characters in common 

 with S. ellipticif oliu8 Hicron., but that species is described as a 

 shrub with ulandular nuberulent peduncles and bracteoles, and 



sh 



7 ' otitis from the 



specimens at hand presents every appearance of a scandent 

 plant, and the leaves in the dried state are dull green and are 

 doubtless rather fleshy in the living state. In foliar characters 

 S. seortifoliu8 suggests S. epiphyticus Kuntze of Bolivia, which 

 has a pronounced fuscous pubescence in the inflorescence and 



on the involucre. It also simulates S. Tonduzvi Greenm. of 



Costa Rica.
