Discussion

Silene ostenfeldii often appears to be inseparable from subsp. tenella except for its wingless seeds. It may be that the two subspecies of S. involucrata, together with S. ostenfeldii and S. hitchguirei, are components of a single variable species with diploid, tetraploid, and hexaploid populations.
