 lanceolate ; pinnl. remote, alternate, petiolate, confluent into an acuminated 

 apex of the pinna, lower ones divaricato-reflexed, middle ones divergent, superior 

 ones patent, all oblong-lanceolate, pinnatifid, unequal at the base, acuminated ;

Hab. Pern, Poeppig. — ^The author compares this with our C. divergens ; but his figure, 

 and a pinna I possess from the author, show a greater resemblance to Hemitelia guianensis, 

 Hk. It is, however, a true Cyalhea, This was quite unknown to me at the time I pub- 

 lished the Sp. Fil. I have since received a pinna from the late Professor Kunze. It is 

 5 in. I., nearly li in. br., oblong-acuminated, quite glabrous ; segments very close-placed, 

 7 hnes 1. by 3-4 br., quite plane.
