 — Tiiis is said to have astern from 3—6 or 8 feet high, and which Mr. Doug- 

 las compares to a small pine-tree, leafy at the top. The stipes is quite 

 smooth, the underside of the frond singularly glaucous, equally so with the 

 Cyathea dealbata of New Zealand ; the pinnules are extremely numerous, 

 small, not exceeding 1 — \\ inch in length, but the pinnEe are ample. 

 In habit and appearance this is extremely distinct from any other Alsophila, 

 and the receptacles are very slightly elevated ; so that it must be consi- 

 dered but a doubtful species of the genus. 



Dubious Species of the West Indies, Mexico and South America. 



36. A. Domheyi, Desv.; "fronds glabrous, pinnules sessile 

 elongato-lanceolale acute slightly pinnatifid, segments obtuse 

 nearly entire oblong, sori near the costa, rachis unarmed." 

 Desr. Prodr. Fil. in Mem. Soc. Linn. v. n. p. 320. Peru. — 

 " Pinnules resembling those of A. aspera, but the sori dif- 

 ferently placed. Involucre unknown." Desv. 



37. A. iMille/olium,'Desv.; " fronds decompound subqua- 

 drifido-pinnate, pinnules dilated at the base acuminato-atte- 

 nuate at the apex, shortly petiolate pinnate, lowest pinnulets 

 petiolate deeply pinnatifid alately adnate, segments elongato- 

 triangular, involucres lacerato-crinite, rachis glabrous unarm- 

 ed above pulverulently pubescent." Desv. I. c. p. 320. — 

 Hispaniola. Desvaux makes no further remark, except to 

 adduce as a synonym the "Filix aurea ramosa, etc., Plmn. 

 Fil. p. 26, t. 33." 



38. A. Schiedeana, Presl; "fronds bipinnate, pinnae deeply 

 pinnatifid. Arboreous, aculeate, nearly allied to Polypodium 

 {Alsopliila) procerum, Willd., from which it differs in the acu- 

 lei, in the pinnules being more deeply pinnatifid, and the seg- 

 ments nearly entire. — Also allied to Pol. pungens, Willd. 

 {Alsopliila, Kaitlf ), from which again it differs in the pinnules 

 being shortly acuminate, more deeply pinnatifid, the segments 

 broader obtuse slightly dilated at the apex ; and in the sori 

 not being contiguous." Scldect. in LimKEa, v. iii. p. 609. 

 Huitamalco and Cuapa, Mexico, {DeCandolle). 



39. A. Martin icensis, Sprengel, Syst. Veget. iv. p. 124. — 

 " Frond pubescent, pinnules lanceolate pinnatifid acuminate 

 entire at the apex, segments oblong obtuse crenate, rachis 

 and stipes hairy. Martinique." — This seems to be taken up 

 from Sieber's published specimens of Martinique Ferns, where 

 a species is given under that name. But if so, it is probably 

 rather a Polypodiaceous plant. 



A. Perinniana, Spreng. 1. c. p. 125, is the same as Wood- 

 sia Perinniana. Hook, et Grev.
