60. ACROSTICHUM. 407 



brown scales, each like a tuft of stellate hairs ; veins conspicuous, very close. 

 H*.Sp.5.p.24l. 



Hab. Mexico to Columbia. Easily distinguished by its texture and clothing. 



41. A. sainoense, Baker ; rhizome short, woody, the scales long, dense, fibril-- 

 lose, glossy, dark chesnut-brown ; st. 4-6 in. 1., clothed with squarrose woolly 

 deciduous hairs ; barren fr. 6-12 in. 1., 1-1^ in. br., the point bluntish and the 

 base narrowed rather suddenly ; texture herbaceous ; surfaces and especially the 

 midrib clothed with soft bright silky brownish hairs ; veins sometimes twice 

 forked ; barren fr. much smaller than the other. Elaphoglossum, Brack, t. 9. 



Hab. Polynesian Islands. Very like the last in texture and general habit, but the 

 scales both of the rhizome and surface are very different. Judging from the figure, the 

 Chilian A. Webbii, Bory, may be identical with this, 



42. A. apodum, Kaulf. ; caud. thick, woody, the scales dense, linear, bright- 

 brown, crisped ; st. tufted, none or short, when present densely clothed with 

 squarrose fibrillose bright-brown scales ; barren fr. 1 ft. or more 1., 1^-2 in. br., 

 the apex acuminate, the lower part narrowed very gradually ; texture subco- 

 riaceous but thin ; the edge and midrib densely fringed with soft short brown 

 hairs ; veins fine, simple or once forked ; fertile fr. much smaller than the barren 

 one. Hk. Sp. 5. p. 213. Hk. & Gr. t. 99. 



Hab. West Indies to Brazil and Peru. The West Indian specimens are thinner and 

 less ciliated than the Continental ones. 



43. A. scolopendrifdium, Raddi ; rhizome woody, short- creeping, the scales 

 long, linear, dark chesnut-brown, crisped ; st. 4-12 in. 1., firm, erect, densely 

 clothed with spreading, nearly black, long fibrillose scales ; barren fr. often 1 ft. 

 1., 1^-3 in. br., the apex acute, the base narrowed gradually ; texture sub- 

 coriaceous ; edge and midrib more or less densely ciliated with scales like those 

 of the stem, but smaller ; veins subparallel, usually once forked ; fertile fr. much 

 smaller than the barren one, Hk. Sp. 5 p. 211. A. barbatum, Karst. A. 

 erinaceum, Fee. 



Hab. Guatemala, along the Andes to Peru. A plant from Fendler has the veins not 

 ^infrequently joining. A. Hystrix, Kze., seems nearly allied. An Ecuador plant from 

 Jameson is densely ciliated not only on the edge, but over the surface. The scales are 

 like those of A . hybridum, but much more copious. 



44. A. Cumingii, Fee ; rhizome woody, the scales large, ovate, dull-brown ; 

 st. 6-8 in. 1., firm, erect, clothed in the lower part with similar scales ; barren fr. 

 8 in. 1., 1^ in. br., the point blunt, the base narrowed gradually, the edge 

 densely fringed with minute scales ; texture very thick ; the upper surface 

 clothed all over with very minute scattered scales ; veins quite hidden ; fertile fr. 

 as long but narrower than the barren one. Fee, Acrostich. 34. 



Hab. Philippines, Cuming, 193. Perhaps a subfurfuraceous variety of decurrens, with 

 which it agrees in texture and general habit. 



45. A. Boryanum, Fe'e ; rhizome woody, the scales dense, linear-subulate, 

 nearly black ; st. tufted, 3-9 in. 1., more or less densely clothed with ovate- 

 acuminate or lanceolate pale-brown scales ; barren fr. often 1 ft. 1., 3 in. br., 

 the point acute, the base rounded ; texture almost papyraceous, flaccid ; both 

 sides thinly clothed with small ovate or peltate furfuraceous scales, which fringe 

 the edge densely ; veins immersed, very distinct, simple or once forked, ending 

 in black dots within the edge ; fertile fr. much smaller and on longer st. than 

 the barren one. Hk. Sp. 5. p. 210. 



Hab. West Indies. The Ecuador plant mentioned in " Sp. Fil." seems to belong to 

 A. scol opendrifolium.
