96 CHEILANTHES. 



3- sub 4-pinnatc, primary ])inna3 patent from a broad base ob- 

 long acuininatc, pinnules orbicular sessile, sterile ones crena- 

 to-lobate in fruit subglobose (from tlie great reflexion of the 

 margins) glabrous above very villous beneath with long lawny 

 hairs, involucre a broad while plane membranaceous margin 

 continued all« round the pinnule. (TAii. CIV. H.) Ch. leu-

 This does not appear to be a common plant in collections; and, notwith- 

 standing the accuracy of Dr. Swartz's description above quoted, I fear it is 

 often confounded with others of the Lc ndii/era-gr ou\t, a small section always 

 more or less copiously woolly or scaly, with the pinnules, in fructification 

 at least, so orbicular and subglobose as to resemble small lentil-seeds, whence 

 more recent authors, supposing that leiitigem (lentil-l)earing) rather than 

 lendigera (nit-bearing) was intended by Cavanilles, have adopted Willde- 

 now's orthography. This species is readily distinguished from its near ally, 

 CA. J«ynopA_yZ/a, Desv.,by the absence of the copious and decidedly chaffy 

 scales of the latter. Ch. lendigera has no true scales, though the hairs some- 

 times become chaffy, i. e., broader and membranaceous at the base. I have 

 seen no specimens from Quito, a habitat given, probably after Cavanilles. 

 My finest specimens were gatliered by Purdie on the Nivada de Sta. Mar- 

 tha, New Grenada. — I cannot consider the Ch. minor of Martens and 

 Galeotti otherwise than as a mere variety of this plant, in which the hairs 

 are so dilated below (though long and slender) as to have a chaffy appear- 

 ance, a character clearly pointed out in their description. 



39. Ch. tomentosa, Link : roots densely tufted fibrous, sti- 

 pites 3 — 5 inches long rather slender ebeneous brown and as 

 well as the ])rincipal rachises clothed with pale erect palea- 

 ceous hairs mixed with copious erect linear-subulate scales 

 broad on the under side of the partial rachises and there close- 

 ly imbricated, fronds 4 — 8 inches long oblong-lanceolate bi- 

 tripinnate copiously clothed above with white woolly hairs 

 beneath densely woolly with tawny tomentum, primary pinnae 

 oblong, pinnides small subrotund or obovate nearly entire the 

 margins recurved and forming a nearly continuous involucre 

 with the edge slightly raembrauacfcous. (Tah. CIX. A.)
