through its dichotomous fronds being borne on scaly stalks and furnished 

 with linear (very narrow), entire segments of a hairy nature. The sori 

 (spore masses) are composed of from three to hve capsules, stalkless and dis- 

 posed on each side of the midvein. — Hooker^ Species Filicum, i,, p. 6.

G. (Mertensia) umbraculifera — Mer-ten'-si-a ; um-bra-cul-if'-er-a 

 (umbrella -bearing), Moore. 

 A greenhouse species, of small dimensions, native of South Africa, and 

 very closely related to the ISTew Zealand G. Cunninghami. Its fronds, often 

 proliferous and of a, soft but fleshy texture, are borne on stalks of a woolly 

 and scaly nature ; they are composed of branches that are dichotomously 

 flabelliform (repeatedly twice-forked and fan- shaped), and are furnished with 

 spear-shaped, comb-like leaflets 4in. to Gin. long, lin. broad, and slightly 

 glaucous (bluish-green) beneath. Their lobes are very narrow, and the spore 

 masses consist of from three to five capsules disj)osed together on each side 

 of the midvein.^ — Hooker^ Synopsis Filicum, p. 13. 



G. (Mertensia) vestita — Mer-ten'-si-a ; ves-ti'-ta (clothed), Blume. 



This is a stout-growing, stove species, native of the Malayan Islands, 

 which may also be looked upon as a large form of G. revoluta, with broad 

 and short segments, large chaffy scales and more distinct veins. Its handsome 

 fronds, many times dichotomous (divided into two) and of a somewhat leathery 

 texture, are dark green above and glaucous (bluish -green) beneath ; their 

 leaflets, Gin. to Sin. long, are all deeply pinnatifid (cut down nearly to the 

 midrib), and their oblong and rather obtuse lobes or segments bear on each 

 side of their midvein the sori (spore masses), which are disposed in groups 

 of five large capsules. — Hooker, Species Filicum, i., p. 10.
