hairs, wMch extend all along the stalks. The fertile fronds, which have their 

 divisions more sharply defined, are borne on glossy, dark chestnut-brown 

 stalks Gin. to 12in. long and upright ; whereas the barren ones, with lobes 

 shorter, blunter, and less divided, are borne on similar stalks, but only 2in. 

 to 4in. long, and their habit is horizontal : both kinds are of a soft, papery 

 texture and pale green in colour. The narrow sori (spore masses) are disposed 

 all along the veins, and are so copious as to eventually become confluent. —

H. pinnata — pin-na'-ta (having pinnate fronds), /. Smith. 



The general aspect of this stove species, native of Jamaica, is that of the 

 better-known Gymnogramme rufa, its fronds, oin. to 6in. long, 3in. to 4in. 

 broad, and borne on glossy, dark chestnut-brown stalks 6in. to 9in. long, 

 being simply pinnate (only once divided to the midrib), but their leaflets are 

 attached to the midrib all the way. These leaflets are oblong-spear-shaped, 

 about IJin. long and Jin. broad, the lowest larger and forked at the base ; 

 they are of a soft, papery texture, and thinly covered on both sides with 

 soft, yellowish hairs. The sori (spore masses) are confined to the veins, —

H. Zollingeri — Zol-lin'-ger-i (Zollinger's), Kurz. 



A singular and pretty, stove species, native of Java, with its curious 

 fronds disposed in a dense rosette. The barren ones, which are nearly sessile 

 (almost stalkless), somewhat spear-shaped, and entire, are 3in. to 4in. long ; 

 the fertile ones, borne on stalks l|in. to 2in. long, are linear (very narrow), 

 3in. long, and about ^in. broad : both are of a parchment-like texture. The 

 sori (spore masses) are dis^DOsed in two or three rows parallel with the midrib 

 and the edge, and are connected by short crossbars also covered with spore 

 masses. — Hooker, Synopsis Filicum, p. 518.
