 Mexico, Ch. Wright, n. 816. — Brief as is tbe account given us of Ch. to- 

 mentosa by Professor Link, we can have little difficulty, though we do not 

 possess authentic samples, in referring to it our specimens of Cheilanthes 

 from Mr. Gordon and Mr. Clias. Wright. Link well observes, " frons 6 — 8 

 pollices longa, pinnfe vix poUicem longffi, petiolus (stipes) cum rachi pills 

 lougis squamiformibus albis : " and further, " affinis Ch. vesiiUe, at differt 

 primo intuitu rachi dense et albo-pilosa, qua; in Ch. vestita pilis laxe posi- 

 tis ferrugineis obsita." Our specimens have the hairs of the u])per surface 

 and margin white, while the tomentum beneath is tawny : — the aspect is 

 much whiter than any of our specimens of Ch. vestita. The whole plant, 

 too, is stouter, intermediate in this respect between Ch. vestita and the fol- 

 lowing, Ch. Bradhurii : — but the chief distinction fi'om the former {Ch. 

 vestita) is to be found in the presence of the erect appressed scales on the sti- 

 pes, rachis, and especially on the under side of the secondary rachises, much 

 the same character, indeed, by which Ch. myriophylla is distinguished from 

 Ch. lendigera, only here the true scales are less numerous, and confined to 

 the underside of the principal rachises, and scarcely conspicuous enough to 

 justify our placing Ch. tomentosa in the following sub-group. 



40, Ch. Bradhurii, Hook. ; root of copious fibres from a 

 short thick horizontal caudex, stipites clustered 5 — 8 inches 

 long stout brown and ebeneous scaly with long glossy ferru- 

 ginous subulate scales at the very base, the rest and the ra- 

 chises densely clothed with long tawny soft woolly hairs mixed 

 with very slender long paleaceous ones, fronds oblong-lanceo- 

 late rigid 8 — 12 and even 14 inches long 3 — 4-pinnate slightly 

 woolly with white deciduous hairs above permanently woolly 

 with short tawny wool beneath, primary pinnules rather dis- 

 tant lower ones more so and petiolate all oblong subacurai- 

 nate, pinnules small oval or obovate entire or only lobed as 

 an indication of more compound pinuation, the margin re- 

 curved with a pale distinct membrane at the edge constituting 

 the nearly continuous involucre. (Tab. CIX. B.)

 me as such by Mr. Lambert ; but possibly one of Mr. Bradbury's, so named 

 by mistake). Affghauistan ? Griffith, in Herb, nostr. — Very closely allied 

 to Ch. tomentosa, Link, it must be confessed ; yet I think distinct in its 

 stronger, stouter habit and larger size, more tawny (for the sparse white 

 hairs on the upper side do not give the hoary appearance so conspicuous 

 in Ch. tomentosa), the absence of real scales (although the hairs are often
