CHEILANTHES. 105 



intensely black glossy subulate scales at the base 8 — 10 inches 

 long slender and as well as the rachises purple-brown glan- 

 dularly hirsute, fronds submembranaceous pale green mi- 

 nutely glandularly pubescent 6 inches long deltoid ternately 

 tripinnate, pinna) (except the lowest usually opposite pair) 

 approximate and compact, upper ones lanceolate, middle ones 

 ovato-acuminate, lowest ones deltoid the lower inferior divi- 

 sions the longest, pinnules rather small obovate convex (the 

 margins much rolled back when dry) lobed or more or less pin- 

 natifid, involucres membranaceous whitish punctiform or more 

 or less continuous frequently the reflexed termination of a 

 lobule. (Tab. XCIII. B.) Link, Fil. Sj?. Hort. Reg. Ber. p.

 I am not aware that this is noticed by any author save Link, who describes 

 it from a cultivated plant in the Berlin Garden, and by Kunze in his 'In- 

 dex Filicum cultarum,' in the 23rd vol. of the ' Linnaea,' who however 

 only changes the name of" viscosa,^' Kaulf. (Link?) to Kaulfussii, on the 

 ground that it is not Ch. viscosa of Cavmichael. Such indeed is the fact ; 

 but as Cai)t. Carmichael's original plant is in my possession, I can testify 

 to its being no Cheilanthes, but a Poli/podium, nearly allied to, if not iden- 

 tical with, P. rugosulum of Mr. Brown's Prodromus. Our figure and spe- 

 cific character are taken from native specimens, which, however, seem to 

 differ in no respect from cultivated ones sent from Berlin to the Eoyal Gar- 

 dens of Kew. It is a well-marked species, though save in the absence of 

 the glandular hairs, a good deal allied to Ch. chwrophi/lla, as far as can be 

 judged from that figure. In the native dried specimens the pinnules and 

 lobes are remarkably convex, in our smaller variety from Sierra Madre par- 

 ticularly so ; giving the ramifications quite a beaded appearance. 



52. Ch. leucopoda, Link ; " frond ternately quadripinnate, 

 ultimate pinnules crenato-pinnatifid with scattered hairs 

 above and below, stipes and rachis whitish, hairs viscid." 

 Link, Fil. Sp. Hort. Keg. Berol. p. 6Q. Kze. in Linnceaf 

 1850, p. 244. 



Hab. Mexico, (Link). — " Frond with the stipes scarcely 4 inches long, 

 primary pinnae an inch and a half, secondary 1 inch, tertiary 4 lines, ulti- 

 mate ones a line long, with long white spreading hairs on the stipes and 

 rachis.'' 



Link, who alone has described this species as above, and it must be con- 

 fessed very unsatisfactorily, places it next Ch. viscosa, but without offering 

 any remarks on its affinities. 



53. Ch. marginata, H. B. K. ; caudex short thick hori- 

 zontal clothed with subulate black scales, stipites 2 — 4 — 6
