Cerastium axillare Correll

Comments

provided by eFloras
Cerastium axillare is similar to C. brachypodum in its short pedicels, but it is more viscid-pubescent, with a much more diffuse habit and solitary flowers widely spaced along the elongate, racemelike primary branches of the inflorescence. In addition, the leaves are usually acute, whereas in C. brachypodum they are usually obtuse. Cerastium axillare is confined in the United States to the trans-Pecos mountains of Texas and New Mexico.
