44. KEPIIRODIUM, § LASIREA. 285 



ture. It hag received many name=, of which Blunie's is the oMest. Polypodium paVi'dum 

 and ncmorale, Brack. Hk. 8p. 4. p. 2G6, are apparently only the ordinary form, witli sup- 

 pressed or undeveloped involucres ; but C'apt. Beddome considers P. ornalum, Wallich, 

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

 of an involucre, h-ee FU. S. Ind. t. 171.

 l)rown, deciduously scaly throughout ; fr. 2-3 ft. 1., 1 ft. br. ; lowest pinnce 

 inucli reduced, tlie largest lanceolate, 0-9 in. L, H-2 in. br. ; /«H?i/. spreading-, 

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

 lobes ; texture herbaceous ; racldses of the pinnte 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, Vleillard and Deplanche. The alliance of this is close with the 

 preceding. 



141. N. (Last.) Grisebachii, Baker ; 5i. 2-3 ft. 1., densely clothed at the base 

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

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

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

 into oblong-toothed sepm. |- in. br. ; texture herbaceous ; colour bright-green ; 

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

 imol. fugacious. — A. amplum, Griseb. {in part, not H. B. K.). N. amplum. 

 Ilk. Sp. 4. p. 264. 



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



142. N. (Last.) amphim, Baker ; st. 2-3 ft. 1,, 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 pinnae 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. 

 verv fugacious. — Aspid. H.B.K. Polyp. Sloanei, Kze. Hk. Sp. 4. p>' 2G3. 

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



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

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



14.8. N. (Last.) catocarpum, Hk. ; st. l|-2 ft. 1., densely clothed at the base 

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

 2nnnce lanceolate-deltoid, 8-12 in. 1., 4-6 in. br. ; pinnl. close, oblong-lanceolate, 

 obtuse, 2-3 in. 1., \-^ in. br., cut down to the rachis below into close, blunt, nearly 

 entire lobes -| in. br. ; texture herbaceous ; racldses 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.) furcatum. Ilk. ; st. 2-3 ft. 1., densely clothed with a mass of 

 very narrow intertangled ferruginous scales ; //•. 3-6 ft. 1., 2 ft. or more br. ; 

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

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

 1^-2 lin. br. ; texture herbaceous; all the racJnses densely clothed with small 

 furfuraceous scales ; castas 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 morp 

 compound and scaly, with the basal scales different. The Galapagos Pobjp. palcaceum, 

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