286 44. NEPHRODIUH, LASTREA. 



145. N. (Last.) villosum, Presl; st. tufted, 2-3 ft. or more 1., stout, usually 

 villose and densely clothed with spreading scales ; fr. 4-6 ft. or more 1., 2-3 ft. 

 or more br. ; pinnae often 2 ft. 1., 1 ft, br. ; pinnl. lanceolate, cut down to the 

 rachis into close, oblong, pinnatifid segm.; largest entire lobes | in. 1., ^ in. br. ; 

 texture herbaceous ; rachises densely villose and both sides also more or less 

 pubescent ; sori copious ; invol. flat, lin. br., often suppressed. Hk. Sp. 4. 

 p. 134. t. 264. 



Hab. West Indies southward to Peru and Chili. A very fine plant, said to attain 

 sometimes a height of 18 ft. The involucre is as often suppressed as developed. 

 P. subinciswm, Karstenianum, Berteroanutn, and vestitum of the Species .Filicum appear 

 to be all villose forms of this without an involucre, and P. spectabile a subglabrous 

 form. See Grisebach's West Indian Flora, p. 691. 



146. N. arborescens, Baker; caud. 10-12 ft. high; fr. ample; lower pinnae 

 12-18 in. 1., 6-8 in. br. ; pinnl. lanceolate, distinctly stalked, 3-4 in. 1., l-]j in. 

 br., cut down to the rachis, except at the point, into lanceolate deeply pinnatifid 

 segm. g-J- in. br., which are obliquely truncate on the lower side at the base ; 

 rachis slightly scaly ; texture herbaceous ; both surfaces naked ; veinlets pinnate 

 in the lobes of the segms. ; sori small, medial ; invol. naked, firm, persistent, 

 very distinctly reniform. 



Hab. Samoa, Rev. T. Powell. 



ft Texture coriaceous. Sp. 147-153. 



147. N. (Last.) Triance, Baker ; st. smooth, stramineous or reddish ; fr. 

 1^-2 ft. 1., 9-10 in. br., broadly oblong, acuminate, tripinnatifid ; pinnce distant, 

 7 in. 1., 2-2^ in br., sublanceolate ; pinnl. numerous, 1-| in. 1., \ in. br., unequal- 

 sided, cuneate on both sides at the base, pinnatifid or subpinnatifid, with close, 

 oblong, usually entire lobes ; texture subcoriaceous ; rachis and both sides 

 naked ; ultimate veins simple, the lower ones on the upper side of the midrib 

 falling short of the edge ; sori dorsal or submarginal ; invol. large, membranous. 

 Aspid. Mett. Fil. Nov. Gran. p. 243. 



Hab. New Granada, Triana. Distinguished by the shape of its pinnules and lower 

 veins not reaching the edge. 



148. N. (Last.) acutum, Hk. ; st. 2 ft. or more 1., firm, smooth, polished ; 

 fr. 2 ft. or more 1., 12-18 in. br. ; lower pinnce oblong-lanceolate, 6-9 in. 1., 3-4 in. 

 br. ; pinnl. linear-lanceolate, J-f in. br., cut about one-third down to the rachis 

 into blunt falcate lobes ; texture subcoriaceous ; rachis and both sides naked ; 

 sori copious, principally in rows close to the midrib. Hk. Sp. 4. p. 147. t. 271. 



Hab. Brazil and Peru. In outline this comes nearest to N. furcatum, but it is quite 

 naked, and more rigid in texture. 



149. N. (Last.) platypus, Hk. ; st. 1-3 ft. or more 1., smooth, glossy, with 

 a dense tuft of bright-coloured scales at the base ; fr. 1-^-2 ft. 1., 1 ft. and more 

 br., deltoid ; lower pinnce 6-9 in. 1., 3-4 in. br. ; pinnl. deltoid, obliquely 

 truncate on the lower side at the base ; lower segm. often free, ^-^ in. br., ovate- 

 oblong ; teeth mucronate ; texture subcoriaceous ; rachis and both sides naked 

 and glossy ; sori large, copious, in rows close to the midrib. Hk. Sp. 4. p. 149. 



Hab. Java, Moulmein, Khasia. A doubtful plant, some of the specimens of which 

 are very like some of the forms of Aspid. aristatum, but with a large, distinctly-reniform 

 involucre. 



150. N. (Last.) hispidum, Hk. ; rhizome stout, creeping ; st. 12-18 in. 1., brown, 

 densely clothed with squarrose, fibrillose, nearly black scales ; fr. 12-18 in. 1., 

 8-12 in. br., subdeltoid ; pinnce lanceolate, the lowest deltoid ; lowest pinnl.
