less, the latter lanceolate, serrulate, less truncate-based than in 
typical . A. lstriformis. Leav ves in general thickish, apple-green, 
straight-serrate, some of them often subentire. Bracts more varied, 
narrower, sometimes acutish. — Widely distributed, in scattered in- 
dividuals or small clumps, in rich soil near rocks, in little shade, 
N. Y. to Va. — Unlike A. aucuparius in lacking acuminate leaves. 
Unlike A. carmesinus in having few cordated leaves. Unlike A 
divaricatus curtifolius, toward which it verges, in its straight-sided 
leaves, more wand-like aspect, etc. Unlike any in its character- 
istic leaf-form, which may however be a peculiar modification of 
that of A. Zistriformis.

Small rock-loving plants with crenate-serrate crisp leaves, per- 
sistent short slender petioles and small deep narrow sinus, widely 
divergent peduncles and shallow inflorescence of segregated 
cymules with deep crimson disks (whence the name, Late Lat. 
carmesinus, crimson).
