 varving in the size and breadth of the pinuiP, which are sometimes a foot and 

 more long, but always terminating in a long, acuminated, narrow point. The 

 mr. /3. has, besides the line forming the linear series near the base, the 

 rest of the numerous sori extending to near the margin of the pinnfe, 

 and the margin is waved and jagged; and in this respect is what >Iartius 

 alludes to, when he says " variat interdum pinnis grosse lobatis et altius 

 dentalis." 



Subgen. II. Trichopteuis. Veins parallel, twice or thrice forked, 

 patent. Sori solitary on the veins or in the upper forks, form- 

 ing a more or less regular or continuous line or series the length 

 of the pinnule. Capsules mi.ved with copious long persistent 

 hairs. — Tropical America. Fronds bipinnate. Pinnae mode- 

 rately large, 4 — 6 inches long. — Trichopteris, Pr^s/. Hook. 

 Gen. Fil. tab. 24. 



2. A. Ticnitis, Hook. ; aculeated, fronds bipinnate, pin- 

 nules lanceolate acuminate glabrous more or less serrated or 

 entire between coriaceous and membranaceous, sori in an un- 

 interrupted series intermediate between the costa and margin.

 pinnules and in the serratures : generally the substance is firm, but not 

 thick, sometimes almost membranaceous. Line or series of fructifications 

 continuous, regular. The copious hairs persist long alter the capsules have 

 fallen away.
