Silene antirrhina
Silene hitchguirei
The six varieties and forms of Silene antirrhina noted above were named on the basis of stature and flower color, but none appear to be worthy of recognition. The species is very plastic, being greatly affected by moisture, exposure, and nutrients.

Silene hitchguirei is similar to S. suksdorfii, except that the latter species has larger seeds, an urceolate fruiting calyx with a contracted base, an inflorescence that is sometimes branched with up to three flowers, and short, erect stems that have three or four pairs of leaves. It is probably closely related to S. involucrata subsp. tenella and S. ostenfeldii but differs in its small size, its usually solitary flowers, and short petals. The wing on its small seeds is narrower than that of S. involucrata subsp. tenella, whereas in S. ostenfeldii the wing is completely absent.
