Has. Caraccas. Linden, n. 663. 
Since the publication of the genus Hemitelia, in our “ Species 
Filicum,” the present one has come to our knowledge in a late 
packet of Mr. Linden’s Caraccas plants. Its nearest affinity is 
assuredly with H. speciosa, Kaulf. (Cyathea, H. B. K.) and of out — 
Sp. Fil. p. 28, t. 13, B.; but it will be at once recognized as dis 
tinct from it by the deeply-lobed, almost pinnatifid, margins of 
the pinne, and by the different appearance of the fructifications+ 
In H. speciosa, as seen in the figure just quoted, the sori form — 
an almost continued line at a slight distance from the crenato- 
sinuated margin; here they constitute a broad band, occupying — 
almost one half of the portion between the margin and the 
costa. :
