44. NEPHRODIUM, LASTREA. 285 



ture. It has received many names, of which Blurae's is the oldest. Polypodium pallidum 

 and nemorale, Brack. Hk. Sp. 4. p. 266, are apparently only the ordinary form, with sup- 

 pressed or undeveloped involuci-es ; but Capt. Beddome considers P. ornatum, Wallich, 

 as a distinct plant, distinguishable from this by its erect caudex and the constant absence 

 of an involucre. 



140. IN". (Last.) subglandulosum, Baker ; st. 1 ft. 1., stout, polished, reddish- 

 brown, deciduously scaly throughout ; fr. 2-3 ft. 1., 1 ft. br. ; lowest pinnce 

 much reduced, the largest lanceolate, 6-9 in. 1., 1^-2 in. br. ; pinnl. spreading, 

 close, 1 in. 1., in. br., cut down nearly to the rachis into close, entire, blunt 

 lobes ; texture herbaceous ; rachises of the pinnae and under side villose and the 

 latter glandular ; sori small, about 6 to the larger lobes, placed midway between 

 the midrib and edge. Aspidium, Mett. 



Hab. Bourbon, Vieillard and Deplanclie. The alliance of this is close with the 

 preceding, 



141. N. (Last.) Grisebachii, Baker ; st. 2-3 ft. L, densely clothed at the base 

 with lanceolate scales 1 in. or more 1., 1-1| lin. br., which leave distinct 

 tubercles when they fall ; fr. 3-4 ft. 1., 2 ft. or more br. ; lower pinnce often 

 1 ft. 1., 6 in. br. ; pinnL close, lanceolate, cut down nearly or quite to the rachis 

 into oblong-toothed segm. % in. br. ; texture herbaceous ; colour bright-green ; 

 rachis very slightly fibrillose and under side naked ; sori small, copious, medial ; 

 invol. fugacious. A. amplum, Qriseb. (in part, not H.B.K.}. N. amplum, 

 HTc. Sp. 4. p. 264. 



Hab. Cuba, G. Wright, 1055. This differs from the next principally in the scales. 



142. N. (Last.) amplum, Baker ; st. 2-3 ft. L, densely clothed at the base with 

 an entangled mass of soft, bright, silky scales ; fr. 3-4 ft. 1., 2 ft. or more br. ; 

 lower pinnce often 1 ft. 1., 6 in. br. ; pinnl. close, lanceolate, cut down nearly or 

 quite to the rachis into oblong, crenated or pinnatifid lobes 2-3 lin. br. ; texture 

 herbaceous ; rachises clothed with soft furfuraceous scales ; under surface naked 

 or slightly glandular, the rachis often scaly ; sori copious, small, medial ; invol. 

 very fugacious. Aspid. U.B.K. Polyp. Sloanei, Kze. Hk. Sp. 4. p. 263. 

 N. Palatanganum, Hk. Sp. 4. p. 260. 



Hab. West Indies southward to Ecuador, and a plant from Pitcairu's Island is probably 

 the same. Asp. lutescens, Willd. (Plum. 34), is most likely this species. 



143. N. (Last.) catocarpum, Hk. ; st. 1^-2 ft. 1., densely clothed at the base 

 with long, linear, pale-brown scales ; fr. 2-3 ft. L, 1^-2 ft. br., subdeltoid ; 

 pinnce lanceolate-deltoid, 8-12 in. 1., 4-6 in. br. ; pinnl. close, oblong-lanceolate, 

 obtuse, 2-3 in. L, ^-^ in. br., cut down to the rachis below into close, blunt, nearly 

 entire lobes J in. br. ; texture herbaceous ; rachises slightly scaly ; under side 

 naked ; sori small, in rows midway between the edge and midrib. Hk. Sp. 4. 

 p. 259. 



Hab. Venezuela. A less compound plant than the last, with larger divisions and 

 different scales. 



144. N. (Last.) fmcatum, Hk.; st. 2-3 ft. L, densely clothed with a mass of 

 very narrow intertangled ferruginous scales ; fr. 3-6 ft. L, 2 ft. or more br. ; 

 lower pinnce 12-18 in. 1., 6-9 in. br., lanceolate or deltoid ; pinnl. lanceolate ; 

 segm. oblong obtuse, cut down nearly to the rachis into close, entire lobes 

 l|-2 lin. br. ; texture herbaceous ; all the rachises densely clothed with small 

 furfuraceous scales ; costce beneath slightly scaly ; sori copious, medial. Hk. 

 Sp. 4. p. 36. 



Hab. Columbia to Peru. This has as large divisions as the last, but is much more 

 compound and scaly, with the basal scales different. The Galapagos Polyp, paleaceum, 

 Hk. Sp. 4. p. 261, probably belongs here.
