 t. 90. — Osmunda hirta, L. {Anemia, Sw. ex cit.) : Plumier's form with a pilose petiole, but 

 the name must be rejected. — Very variable, li'~¥ high ; lower leaf-segments 1" long, 4 

 broad.— Hab. Jamaica {Sw.) ; Trinidad!, Lockh., on roadsides, rare; [Haiti and Mexico 

 to Brazil !]. 



10. A. humilis, Sw. Sterile leaf-segment pinnatisect, sessile, membranaceous, hairy, 

 or glabrescent: special segments 10-5-jugal, spathulate, blunt, serrulate, cwneate rfw

free.—Schk. Crypt, t. 141./. sin.— Osmunda, Cav.—4,"-8" high; secondary leaf-segments 

 10"'-6'" long, 4"'-2'" broad.— Hab. Jamaica !, Pd. ; [Mexico! to Peru ! and Brazil!]. 



11. A. hirsuta* Sw. Sterile leaf-segment pinnatisect, sessile, chartaceous, hairy: se- 

 condary segments pinnatipartite, or pinnatijid, striate above by prominent, flabellate, forke

 mon rhachis pilose. — Plum. Fil. t. 162.— Osmunda, L. A. dissecta, Prl. {Rel. H<enk. t. 11. 

 /. 4 j Si. t. 25. /. 6) : the form with pinnatipartite secondary segments. — l£'-i n, n" » 

 primary leaf-segments 15"'-6'" long, uppermost decrescent. — Hab. Jamaica!, all coll., com- 

 mon, Port Royal, S. Andrews, at 4000' alt.; [Cuba! and Mexico to Brazil! and Tucu- 

 man !]. 



12. A. adiantifolia, Sw. Sterile leaf -segment deltoid, 2-pinnatisect, shortly petiolu- 

 late, chartaceous, glabrous above, glabrescent beneath : tertiary segments upwards decrescent 

 pinnatipartite-few-serrate or lowest pinnatisect, ultimate cuneate-elliptical, bluntish, denticu- 

 late above,slriate by prominent, flabellate-dichotomous,//-^ veins : axis usually hairy. — Plum. 

 Jil.t.\$%. Hook. Grev. Ic. t. 16.— Osmunda, L. A. aspleuifolia, Sw.—l'-H' h, £ h;
