N. (Eunephrodium) Hookeri— Eu-nepli-ro'-di-um ; Hook'-er-i (Hooker's). 

 Synonymous with N. Arhuscula. 



N. (Lastrea) Hopeanum — Las'-tre-a ; Ho-pe-a'-num (Lieut. Hope's), 

 Baker. 



A stove species, of medium dimensions, native of Polynesia, with oblong- 

 spear-shaped fronds 1ft. long, 6in. to 7in. broad, borne on naked, glossy grey 

 stalks Ift. to IJft. long, and bipinnatifid (twice divided nearly to the 

 midrib). The distant, stalkless leaflets are cut down to a narrow wing into 

 strap-shaped, entire lobes of a somewhat leathery texture and dull green on 

 both surfaces. The sori (spore masses), disposed in a crowded manner close 

 to the midrib, are covered by a firm involucre of a persistent nature. — Hooker, 

 Synopsis Filicum, p. 494. Nicholson, Dictionary of Gardening, iv., p. 573. 



N. (Lastrea) Hornei— Las'-tre-a ; Hor'-ne-i (Home's), Baker. 



A stove species, native of the Seychelles. Its large fronds are deltoid 

 (in shape of the Greek delta. A), 2ft. to 3ft. each way, quadripinnatifid (four 

 times divided nearly to the midrib), and borne on robust stalks of a naked, 

 glossy nature. The lowest leaflets, also deltoid, are much the largest ; their 

 lowest leafits (pinnules) and segments, closely set and spear-shaped, are sharply 

 pointed at their extremity and winged to the base ; the final lobes are oblong 

 and notched. The fronds are of a parchment-like texture, smooth, and bright 

 green on both surfaces. The small sori (spore masses), nearly marginal and 

 restricted to the lobes, are covered with a smooth and somewhat persistent 

 involucre. — Hooker, Synopsis Filicum, p. 500. 



N. (Eunephrodium) Hudsonianum— Eu-neph-ro'-di -um : Hud-so-ni- 

 a'-num (Hudson's). A synonym of N. truncatum. 



N. (Lastrea) inaequale— Las'-tre-a ; in-a3-qua'-le (unequal). Hooker. 



This is a greenhouse species, native of Cape Colony and Natal ; it is of 

 medium dimensions, intermediate in habit between N. spinuloswn and the 

 large forms of N. Filix-mas. The fronds, borne on stalks 1ft. or more long, 

 with a dense tuft of reddish-brown scales at the base and a few spreading 

 upwards, are 1ft. to 2ft. long and Sin. to 12in. broad, and have their lower 

 leaflets rather shorter and broader than the others, which are 6in. to Sin. long
