5a. Cheilanthes Covillei intertexta Maxon, subsp. nov. 



Similar in general characters to C. Covillei, but differing in its smaller, 

 shorter-creeping, subnodose rhizomes, its darker green and relatively 

 larger lamina segments, and conspicuously in the vestiture of the lamina; 

 segments bearing one to several greatly reduced, whitish, stellate, subper- 

 sistent scales above, thickly clothed beneath with several to numerous, 

 bright castaneous to cinnamomeous, imbricate scales, these highly variable 

 in size and ciliation, the larger ones (like those of the secondary and ter- 

 tiary rachises) mostly deltoid-lanceolate, long-attenuate, sinuate-dentic- 

 ulate nearly throughout, freely long-ciliate at the cordate base, these 

 scales underlaid by others successively smaller and more copiously ciliate, 

 the ultimate ones very greatly reduced (body of scales nearly obsolete), 

 entangled and not separable, forming a loose tomentum held in place by 

 the crenulate, widely revolute border of the segment.
