Hab. Venezuela, and in Mexico, Schiede, 7i. 800.— Our fisme and spe- 

 cific charaetcr are taken from specimens kindlv sent to us by Dr. Sonder, 

 gathered at I-a Guayra l)y Moiitz, {Coll. III. 7i. 263). It is a very ele- 

 gant and we believe very distinct species, belter deserving the name of 

 micmphylla than the Ch. 7nicrophi/lla, Svv., with which it has been com- 

 pared, and which Kunze says differs " frond e ba si baud dilatata, semper 

 bipiiinata, pinnis ultimis majoribus, rachi primaria valida stipiteque brevi 

 dense rufo-paieaceis.'' To us its nearest affinity seems to be Ch. tenuifo- 

 lia; but it is much more delicate in all its parts: the primary pinnae arj 

 more numerous, more approximate, and the ultimate pinnules and lobes 

 are move cnneate at their base. Our figures will show the differences better 

 than words can do. 



17. Ch. elongaia. Willd. Herb.; " fronds bipinnate, lower 

 pinnules sinuato-pinnatifid obtuse glabrous, indusiura obso- 

 lete subcontinuous." Kaulf. En. p. 213, (not Kl. MSS.J 

 C. Linkiana. Kze. C. microphylla, Lk. (not Sw.J Kunze, 

 in Linnoca, xxiii. p. 213. 



Hab. \V. Indies, Hispaniola, {Kaulf) — "Son. contiguous confluent. 

 Involucres obsolete, sub-continuous and ciliated." — Such is all the descrip- 

 tion we have of Willdenow's Ch. elongata. But from some of Kunze's re- 

 ferences I judge it may be placed near Ch. Moritziana, Kze. 



18. Ch. ohtusata,Fr.; " fronds oblong glabrous bipinnati- 

 fid, pinnae sessile subopposite oblong-lanceolate obtuse deeply 

 ])innatifid, laciniae ovato-oblong obtuse, lower ones inciso- 

 crenate, involucres dentiform, rachis and costse villous be- 

 neath, stipes flexuose, caudex creeping paleaceo-villous."

Hab. Mountains of Peru, Heenke. — " Ab affini Ch. microphylla, Sw., dif- 

 fert froude bipinnatifida, laciniis infimis inciso-crenatis, rhachi costaque 

 villosis, caudice repente villoso." I have seen no Cheilanthes like this from 

 the Peruvian Andes. The figure shows no analysis, and nothing is said of 

 the fructification. 



19. Ch. crenata, Kze.; "frond linear-oblong pinnato-pin- 

 natifid glandulosely hairy, pinnae subopposite sessile ovato- 

 oblong, segments ovate or shortly oblong truncate ultimate 

 ones confluent crenate subincised, involucres at length obso- 

 lete, rachis pale and as well as the stipes short brown and 

 paleaceous at the base glandiilarly rough." Kunze, in Lin- 

 van, ix. p. 84.
