without hirsute hairs; leaves 13-15 mm. long, entire; flower-heads 
compact, five- to ten-flowered; floral bracts 14-22 mm. lo 
three-parted, the divisions slender, pubescence soft-puberulent with 
an occasional hispidulous hair, tips truncate or with a tack-like 
enlargement of the veins, not distinctly calloused; lower calyx-leaf 
at least 2 mm. longer than the upper, pubescence as on the bracts;
