CHEILANTHES. 101 



Hiiniile sessile orbicular and subglobose from the inflexcd 

 fructified margins glabrous above very liairy beneath, involu- 

 cres a continuous mcnibrane forming a pale edge to the 

 recurved margin (the hairs of the partial rachiscs and of the 

 under side of the pinnules often long and crisped and more 

 or less enveloping the whole of the minute pinnules). (Tab.

 and near Oaxaca, Mexico, Andrieux. — A species first distinguished from 

 Ch. lendigera by Desvaux. It is much smaller than that, has tufted stipi- 

 tes springing from a small nodose caudex, narrower fronds, copiously clothed 

 at the back with scales (springing from the rachises) as well as hairs, smaller 

 but equally rounded, and sessile pinnules. Kunze's Ch. elegans, of his dis- 

 tributed specimens, is clearly our Ch. myriophylla. He refers the Ch. 

 myriophylla of H. B. K. to his Ch. elegans, but whether justly so or not T 

 am unable to say. 



45, Ch. Lindheimeri, Hook. ; caudex very long about as 

 thick as a crow-quill creeping branched and entangled clothed 

 with brownish scales, stipites scattered 4 inches to a span 

 high ebeneous beset with subulate narrow lanceolate cinere- 

 ous appressed more or less deciduous scales, more abundant 

 upwards and in the rachises where they are copiously mixed 

 with larger ovate fimbriated brown scales covering the under 

 side of the pinnae and fine cinereous wool which more or less 

 densely covers and conceals the upper side of the pinna?, 

 fronds 3 — 5 inches long ovato-lanceolate subcoriaceous tri- 

 pinnate, primary pinnaj oblong acuminate approximate lower 

 ones more distant nearly opposite, secondary pinnules crowded 

 linear oblong, pinnules very minute densely crowded sessile 

 subglobose glabrous above woolly beneath the margins much 

 recurved, involucres formed by the continuous recurved mar- 

 gins having a very narrow membranous edge. (Tab, CVII. A.)
