27. A. Sprengelinna, Mart. ; " frond bipinnato-partite, sti- 

 pes aculeate and as well as the rachis and veins sparingly- 

 downy, pinna; oblongo-lanceolate acuminate, pinnules linear- 

 oblong much cuspidate, segments between the rather acute 

 sinuses obliquely linear-oblong rather obtuse denticulate on 

 the superior margin, the lower posterior segment of each pin- 

 nule shorter but not decurrent, sori 8 — 10 occupying the 

 whole segment." Martins, PL Crypt. Bras. p. 75. " Cya- 

 thea armata, Spreng. in Herb. Bertero'''

28. A. atrovirens, Presl ; " fronds compound, pinnae pin- 

 nate subpetiolate, pinnules sessile broadly lanceolate coarsely 

 and pinnatifidly dentato-serrate denticulate, sori scattered or 

 arising from an hemispherical receptacle, stipes with short 

 spines (arborescent)." Polypodium atrovirens, Langsd. et 

 Fischer, Fil. Bras. p. 12, t. 14. IVilld. Sp. PI. v. v. p. 188. 



Hah. St. Catherine's, Brazil, Langsdorff. — This is, no douht, as Presl 

 has rightly judged, an Alsophila : and, so far as can be inferred from the 

 figure, nearly allied to A. procera, or perhaps A. Hookeriana. 



29. A. radetis, Kaulf ; " fronds bipinnate, pinnules linear- 

 lanceolate pinnatifid, segments oblong obtuse nearly entire, 

 rachis aculeate beneath, costa paleaceous." Kaulf. En. Fil. 

 p. 248. 



Hab. Brazil, Chamisso. — "Pinnae about 2 feet long; pinnules Ij — 2 

 inches. Sori minute, globose, inserted upon the receptacle, parallel with 

 the costa of the segments and arising from the middle of the veinlets. In- 

 volucres scarcely any." 



30. A. setosa, Kaulf.; "fronds tripinnate, secondary pinnae 

 lanceolate acuminate pinnated at the base glaucous beneath, 

 pinnules linear subfalcate toothed at the apex, partial rachis 

 flexuose setose above, costulae beneath with chaffy ciliated 

 scales." Kaulf. Enum. Fil. p. 249. 



Hab. Brazil, Chamisso. — "Plant very large. The specimens which I have 

 examined have the general rachis about as thick as the little finger, rather 

 rough ; the primary pinnae more than 1 foot long, secondary 3—4 inches; 

 sori globose covered with a very thin, torn, reclinate involucre, of which 

 from 8 — 10 are inserted on each pinnule," (segment). — It is singular that 

 with so evident an involucre as he describes, Kaulfuss should not have re- 

 ferred this Fern to Cyathea. 



31. A. pi/cnocarpa,Kze.; " frond bipinnate, pinnae alter- 

 nate petiolate, petioles thickened at the base, pinnules sub- 

 sessile lanceolate ci-enato-serrate or subincised, the apex 

 obtuse subfalcate entire, sori clustered on the segments, ra-
