Hab. Mexico, Elmnberg. — A very pretty and distinct species, judging 

 from Kunze's tiguie, with an exceedingly pale straw-coloured stipes. The 

 pinnae very unilorni, deeply pinnatifid with oblong segments, and in the 

 principal figure at least having a continuous involucre like Pteris or Allo- 

 sorus. 



64. Ch. aspera, Hook. ; roots densely tufted, stipites 2 — 3 

 inches long and as well as the main rachis and lower half of 

 partial rachis ebeneous rough with minute points and partially 

 scaly, scales pale ash-colour, fronds 4 — A^ inches long lan- 

 ceolate bipiunate subcoriaceous pale green, primary pinnaj 

 distant below petiolate from a broad base ovato-acuminate, 

 pinnate below pinnatifid above, pinnules and segments broad 

 oblong when sterile, linear when fertile, entire or slightly au- 

 ricled on each side at the base crenato-undulate towards the 

 margin and there especially rough with short harsh white 

 hairs often bi-tripartite or geminate, involucres continuous 

 formed of the reflexed margins pale and membranous at the 

 edges crenate and transversely undulate, on the ridges of the 

 undulations the white rigid hairs are particularly apparent.

Hab. Collected in an Expedition from Western Texas to El Case, New 

 Mexico, Ckas. Wright, 1849. — This has a good deal the habit and general 

 appearance of Cheilanthes canesccns of Kunze, and has as much claim to be 

 placed in the genus as that species, the continuous involucre being however 

 that of Pteris or AUosorus. Our plant is much more delicate and graceful, 

 the stipes and main rachises ebeneous, the primary pinnte again truly pinnate. 

 But the remarkable character exists in the transversely waved margin of 

 tlie fertile pinnae and segments, and the harsh rigid sim|ile or bi- and some- 

 times tripartite white hairs seen on the ridges, especially of the undula- 

 tions. It is assuredly a very distinct and new species. 



65. Ch. caudata, Pr. " fronds bipinnate subtriangidar gla- 

 brous, pinnules pinnatifid, lateral lobes roundish, terminal 

 one linear, sori confluent, involucres obsolete, rachis and sti- 

 pes glabrous." Br. Prodr.p. 156. 



Hab. Tropical New Holland, Brown. — I have seen a specimen of this 

 in the Banksian Herbarium, and know of nothing exactly corresponding 

 with it : yet, without more specimens for examination I would not venture 

 to describe it, or to say it is decidedly distinct. It has some aflinity with 

 small specimens of Ch. tenuifolia, but it has very elongated terminal pin- 

 nules, both at the main apex of the frond and on the branches. It may
