102 CHEILANTHES. 



any described one. The copious scales on the under side of the frond readily 

 distinf^uish it from Ch. lendigera, which it resembles in the long creep- 

 ing cauilcx. The rounded sessile pinnules keep our plant distinct from 

 Ch. elegnns, and the very woolly or tomcntose upper side of the frond, the 

 very crowded pinnules and secondary pinnae and compact habit, and above 

 all the long creeping caudex separate it both from Ch. elegans and Ch. 

 v^yrinphtjlla. 



46. C\\. elegans, Desv. ; roots tufted, caudex scarcely any 

 nodose clothed with dark brown appressed bristly scales, sli- 

 pites tufted a span to nearly a foot long clothed as well as 

 the rachises with numerous pale brown hairs, the partial ra- 

 chises in addition with copious brown fringed scales conceal- 

 ing the under side of the pinnules, main rachis often zigzag, 

 fronds a span and more long broad-oblong or ovato-lanceo- 

 late tripinnate acuminate, primary pinnules often lax from a 

 broad base oblong acuminate, secondary pinnae lanceolate 

 rarely again pinnated, pinnules very minute glabrous above 

 villous beneath obovato-globose (subpyriform) with the mar- 

 gins much recurved tapering at the base (especially the termi- 

 nal ones) into a distinct short petiole, involucres apparently 

 formed of the recurved margin of the pinnules with scarcely 

 any membranous edge, (hairs of the partial rachis and under 

 side of the pinnules woolly with the wool concealing more or 

 less the entire minute pinnules). (Tab. CV. B.) Desv. in

 mante, eastern side of the Cordillera of Chili, Dr. Gillies. — This species 

 was, as well as our Ch. myriophtjlla, first distinguished by Desvaux, and 

 assuredly the majority of our specimens have the minute pinnules so dis- 

 tinctly tapering into a petiole, generally too accompanied by a broader 

 form of frond, a more lax habit, and frequently a zigzag main rachis, that 

 the differences are almost perceptible with the naked eye, and distinctly seen 

 with a small power of the lens. Others again have the side pinnules almost 

 if not occasionally quite sessile, though the terminal pinnule is petiolate ; 

 so that I am sometimes led to doubt of the permanency of the character. 

 Both in Ch. myriophylla and Ch. elegans the same copious scales accom- 

 pany the hairs on the rachises, covering and concealing the under side of 

 the pinnules : and in both the hairs of the partial rachises and of the un- 

 der side of the pinnules are so long and woolly as to cover and partially 

 conceal the upper side of the pinnules.
