Distribution, common names and uses 



Bombacopsis j'endleri is a well known tree within the li- 

 mit s"~o?~Panama'^ v/here it goes under the name of cedro espi - 

 noso , but has not heretofore been reported fro.i the coun- 

 tries to the south and east, neither from Ccsta Hica, 

 wljere it is supposed to extend northv;estwards to seme dis- 

 tahce along the Pacific coast. It .^refers the semi-dry 

 climate of the southern watershed and crosses the Isthmus 

 only through the gap formed by the Ghagres Valley. 



Superficially, the wood looks very much like that of 

 the several Sj..ecie3 of Cedrela, except for its ^jaler color. 

 It is extensively used in Manama for the inside wood-work 

 cf houses. 2he supply, hcv/ever, is limited, as the tree is 

 never very large and grov/s in isolated specimens.
