Calea nana is generally distributed in the Sipapo Cumbre, being one of the 

 characteristic species of the more moist open areas. It is most closely related 

 to C. abelioides Blake of Cerro Duida, which is a larger shrub with smaller umbel- 

 late 10-flowered heads, essentially glabrous stems, and conspicuously glandular- 

 punctate "5-ply" larger leaves (having 5 strong nerves arising near the base of 

 the blade).

TYPE: slender shrub with yellow flowers, terraces, East Basin, 1900 m. 

 alt., Cerro Sipapo, Amazonas, Venezuela, January 21, 1949, Bassett Maguire, Jr. 

 & Loliis Politi 28505, unicate; New York Botanical Garden. 



Unfortunately only the single specimen was collected by Mr. Politi and Bas- 

 sett Maguire, Jr., associates on the Sipapo Expeditionc Undoubtedly a most char- 

 acteristic and attractive shrub is represented by this specimen. The species is 

 not immediately related to Calea kunhardtii, its closest congener on Cerro Sipapo.
