Taimyr Catchfly

Silene ostenfeldii (A. E. Porsild) J. K. Morton

Comments

provided by eFloras
Silene ostenfeldii, an amphi-Beringian species, is very similar to S. involucrata subsp. tenella. However, it lacks the wing on the seeds, and its mature calyx tends to be more elliptic than campanulate. It may be confused also with S. sorensenis, but that species has larger seeds and calyces and is a sturdier plant with a denser, longer, somewhat woolly pubescence.
