G. (Selliguea) heterocarpa — Sel-li'-gue-a ; het-er-oc-ar'-pa (having 

 variable fruit), Bluiiie. 

 In this stove species, of medium dimensions, native of Java, the fronds, 

 borne on firm, erect, naked stalks 6in. to 9in. long, are produced from a wide- 

 creeping rhizome (stem) of a woody nature, densely covered with linear (long 

 and narrow), brown scales ; they are simple (undivided). Gin. to 12in. long, 

 lin. to 2in. broad, very pointed at their summit, and very gTadually narrowed 

 at their lower part ; their texture is somewhat leathery and both surfaces 

 are naked and glossy. The linear- oblong, immersed sori (spore masses), are 

 disposed one between each main vein, and do not extend either to the edge 

 or to the midrib. — Hooker^ Species Filicum, v., p. 160. 



G. (Eugymnogramme) hirsutula — Eu-gym-nog-ram'-me ; hir-su'-tul-a 

 (slightly hairy), Mettenius. 

 A stove species, from ]S[ew Granada, very closely related to G. angustifrons 

 of Baker, from which it ditfers only in being of a less hairy nature and in 

 its fronds not being enrolled at the point. — Hooker, Synopsis Filicum, p. 380. 



G. (Eugymnogramme) hirta — Eu-gym-nog-ram'-me ; hir'-ta (hairy), 

 Desvaux. 



This stove species, native of Columbia, - is of a peculiar aspect, on account 

 of its pretty fronds, of an elongated-triangular shape and quadripinnatifid (four 

 times divided half-way to the midrib), being borne on tufted stalks 6in. to 

 12in. long, dark chestnut-brown in colour, and slightly hairy. The leafy 

 portion, 6in. to 12in. long and 4in. to Sin. broad, is of a firm, papery texture, 

 the lower leaflets being triangular, and the whole of it is more or less hairy 

 on both sides. The sori (spore masses), disposed one to each lobe, become 

 confluent in the centre of the segments.— i7c>c»-te?". Species Filicum, v., p. 133. 



G. (Eugymnogramme) hispida — Eu-gym-nog-ram'-me ; his'-pid-a 

 (hispid or hairy), Mettenius. 

 This greenhouse species, native of New Mexico and the Valley of the 

 Rio G-rande, and G. triangularis, are, according to Eaton, the only Gymno- 

 grammes found in a wild state in jSTorth America — where G. hispida is also 

 abundant along the San Pedro and the Gila, growing mostly on rocks. Its
