 — Dr. Martins com|)ares this with A. armala (our A.ferox), from which it 

 appears to me very distinct. Presl calls this Als. munita, Kaiilf., but I 

 know not upon what authority; for it is a species I find nowhere described. 



23. A.hirsnta, Kaulf. ; "frond tripinnatifido-partite slight- 

 ly hairy on both sides csjieoially beneath, and there furnished 

 with little scales, stipes and rachis aculeate beneath, and as 

 well as the partial rachis rough with hairs, pinna? linear-ob- 

 long shortly acuminate deeply pinnatifid, segments broadly 

 lanceolate inciso-semipinnatiiid, the ultimate segments ob- 

 liquely ovate acutely serrate above, sori in each segment 8 — 

 16." A. hirta, Kaulf. Eu. Fit. p. 249. Martins, PI. Crypt.

 — Gaudithaud has adduced the Polijpinlium axillarp, Raddi, as a synonym 

 to this plant, and probably correctly. 



24. A. riyiiluln, Mart. ; "frond bipinnato-partite rather firm 

 ovato-rhomboid flocculoso-pubescent especially beneath, sti- 

 pes clothed at the base with long whitish ciliated scales and as 

 well as the rachis aculcolate nodulose slightl}'- hair}' above in 

 the middle, pinnules lanceolate rather obtuse at the base on 

 the lower margin subdecurrent ])innatifid and crenate, the 

 ultimate confluent into a serrated acumen, sori 2 — 4 — 6 in 

 each segment." Martius, PL Crypt. Bras. p. 74, t. 51.

25. A. nigra, Mart.; "frond bipinnato-partite slightly hairy 

 the hairs spreading, scales none, sti})es and rachis aculeate, 

 partial rachis and veins hairy, pinuic linear-oblong acumi- 

 nate, pinnules linear acuminate pinnatifid, segments between 

 the rather acute sinuses linear-oblong obtuse crenato-dentate 

 in the superior margin, sori 8 — 10 covering the whole seg- 

 ments." Martius, PL Crypt. Bras. p. 71, t, 47.

26. A. f nun ticola. Mart. ; "frond bipinnato-partite, rachis 

 and nerves villous below and above villoso-tomentose, the rest 

 of the plant nearly glabrous above downy beneath, ]iinnie and 

 pinnules oblongo-lanceolate acmninate, segments of the pos- 

 terior pinnie linear-oblong pinnatifido-serrate, the .serratures 

 acute nearly entire, sori 6 — 10 on the segments, segments of 

 the superior pinnae toothed with the sori nearly solitary."
