this species, indeed has seen no specimens of it except from central 

 and southwestern Colombia where it appears to be abundant. If 

 Hieronymus is correct in his identification, the plant of von Jelski 

 extends the known range southward toward 1000 km.

This species is not closely related to any other in Peru. Its leaves 

 recall those in some species of Baccharis, the genus to which it was 

 first referred. [Brazil, Argentina, Bolivia.]

44. E. CALLACATENSE Hieron. Suffruticose; branches slender, 

 terete, spreading, flexuous, covered with short dense somewhat 

 deflexed brownish-gray scarcely or not at all glandular pubescence;
