Polypodium prasinum Bak. Syn. Fil. 312, 1867; ?Sod. Cr. vasc. quit. 292. 
Dryopteris prasina C. Chr. Index 285, 1905. 
Type from Peru, Tarapoto, Mt. Guayrapurima, leg. Spruce nr. 4719 (Kew !, 
also RB). I consider Spruce nr. 4719 the type-number of this species, to which the 
first name of the plant, Pol. punctatum Spruce, was given by Spruce; his nr. 5714 
from Chimborazo (Kew, RB) belong to St. ichtiosma. S. prasina is fully bipinnate; 
the lower pinnule are free but broadly adnate to costa, lobed nearly half of the 
way down to the midrib into square or rectangular, entire or faintly serrated lobes; 
veins pinnate in the lobes, 3—4 to a side, simple. Sori about medial, without an 
indusium-like scale as in S. ichtiosma. — Plant very large, up to 2 m. high; stipe 
at base with many squarrose scales, which are up to 3 cm. long. Rachis, costze 
and costule beneath richly fibrillose by reddish scales. Pinnz 35 cm. or more 
long, lanceolate, shortstalked, 6 cm. broad at the middle; pinnule about 4 cm. 
long, 1 cm. broad. Lamina thin, grass-green, paler beneath, very distinctly pellu- 
cido-punctate. 
A specimen from Ecuador, Andes of Quito, Soprro (B) may be specifically 
different. It is Pol. prasinum Sod. Cr. vasc. quit. 292. It is much larger than the 
Peruvian type and less scaly. The pinne are distinctly stalked, the pinnules ses- 
sile, 10 cm. long by 2 cm. broad, incised */4 of the way down to the midrib into 
obtuse, serrulate segments. Veins in about 5 pairs to a segment, as a rule forked 
near the middle, the anterior branch very short and soriferous. In texture, colour 
and immersed glands the specimen agrees with S. prasina.

Type from Trinidad, leg. GERMaiN (Herb. Mus. Paris!). — Bot. Gard. Herb. 
Trin. nr. 1225 (W); Aripo-Savannah ,im schattigen Walde an Baume kletternd*, 
OrHwER nr. 116 (Herb. Monac, C, CC). British Guiana, Essequebo, APPUN nr. 
27 (B, RB). 
This is a most distinct species. Leaves somewhat dimorphous, the sterile 
ones being considerably broader than the fertile ones, about 10 cm. long by 2 cm. 
wide, short-stalked, truncate at the upper base but scarcely auricled, cuneate at the 
lower one, the margins subentire or repand or broadly serrulate, always sharply 
serrate towards the apex.  Fertile leaves with pinnz scarcely more than 1 cm. 
broad, very variable in cutting, being from almost entire (the serrated apex ex- 
1) The species of this group I have not named Stigmatopteris but use the names of Index Filicum.
