ALSUi'HiLA. S9 



Jlouutaius («. 114) aud Tejuco («. 5673) Gardner. — Quite different from 

 any previously described species of the genus; the pinnules, 2 — t inches 

 long, being very slightly jiinnatifid, the segments sliort and blunt; the 

 son dispersed over all the pinnatifid jxirtion. 



8. A. HookeriiDui, Klotzsch ; slij)c.s and racliis strongly 

 aculeated, fronds everywhere glabrous or pubescent on the 

 partial racliis subcoriaceous, pinnules shortly petiolate lan- 

 ceolate slightly and obtusely acuminated cuneute at the base, 

 segments short rounded obtuse oblique quite entire, veins sim- 

 ple and forked, sori in 2 series half-way between the costa and 

 margin, bullate scales none, receptacles elevated hairy, rachis 

 of the pinnx winged between the upper pinnules. A. Hook- 

 eriana, Klotzsch in Herb. Key. Berol. 



Hab. South Brazil, Sellow. St. Catherine's, Lai/ and Collie. — This I 

 was at first disposed to make a variety of the preceding, but it is probably 

 different : the stipes is very much aculeated, the fronds are more coriace- 

 ous, the pinnules not truncate at the base nor by any means so acuminated 

 at the apex, the veins are more frequently forked, the receptacles more hairy 

 and the capsules less crowded and compressed. A distinct wiug appears ou 

 the rachis of the pinnae, between the upper pinnules, in which respect it re- 

 sembles the following species. 



9. A. armiyera, Kze. ; " fronds bipinnate, pinnules nearly 

 sessile falcate lanceolate the upper ones abbreviated inciso- 

 pinnatifid, the segments obtuse or truncated, sori forming a 

 line along the veins of each segment, partial and universal 

 rachis winged above and hairy rough beneath, stipes acule- 

 ated above, beneath rigidly paleaceous. Alsophila .'' armige- 

 ra, Kze. Syn. Plant. Crypt. Poep. p. 98. 



Hab. Ventanilla de Cassapi (Maynas, in Herb, nostr.), Poeppiif. — Allieil to 

 A. proccra, but partially downy, very downy on the main rachis. Pinnules 

 also larger and rather more deeply pinnatilid. On the underside the veins 

 are nearly of the same color as the frond : in that respect approaching ^4. 

 aspera. There are hairs among the sori on the receptacles. 



The above four preceding species differ from the rest of this group, 

 in the shallow segments of tlic pinnules, the deepest of them not being cut 

 half way down to the rachis. The following species however, A. aspera, is, 

 as it were, intermediate in that respect. 



10. A.aspe)a,BY. ? ; stipes and rachis aculeated, mahi and 

 partial rachis above strigillosc slightly scaly beneath and on 

 the costa the rest glabrous shining, fronds bipinnate coriace- 

 ous, pinnules shortly petiolate oblong pinnatifid one half or 

 two thirds the way down with an acuminated point, segments 

 oblong-ovate rather acute serritlate, costa and simple or fork- 

 ed veins of the same color and texture as the frond, bearing 

 small bullate scales, sori very deciduous in '2 series interme- 

 diate between the costa and margin, receptacles moderately 

 elevated with few hairs. A. aspera, Ih.Y flook. ct Grev. Ic.
