Notes: FNA5:"The wholly herbaceous bracts of Cerastium brachypetalum distinguish it from C. fontanum subsp. vulgare, C. semidecandrum, and C. pumilum; the ciliate petal and filament bases distinguish it from C. diffusum and C. glomeratum. Cerastium brachypetalum differs from all those species in the long, silvery hairs that give it a grayish appearance. In Europe C. brachypetalum is more variable and eight subspecies have been recognized, two of which—subsp. brachypetalum and subsp. tauricum—occur in North America. However, they differ only in the absence or presence of glandular hairs, an insufficient distinction for recognition at the subspecific level."
