Siberian Spikemoss

Selaginella sibirica (Milde) Hieron.

Comments

provided by eFloras
Selaginella sibirica is most closely allied to S . rupestris . In addition to differences noted in the descriptions, it can be distinguished from S . rupestris by the numerous marginal cilia on the leaves and by the transparent sporophyll margins; S . rupestris has a variable number (usually few) of marginal cilia and nontransparent sporophyll margins.

Selaginella sibirica

provided by wikipedia EN

Selaginella sibirica, the Siberian spikemoss, is a species of spikemoss that can be found in dry or exposed rocks and ridges from Alaska to the northwestern region of the district of Mackenzie[1] as well as in northern Russia. The linear leaves are grooved on the back, 2.5-3 millimeters long, including the seta, and usually truncate near the top. Sporophylls are ovate to triangular, and are shorter than the leaves.[2] It looks similar to S. densa, though it can be distinguished by its white setae, compared to the yellow setae of S. densa. Although all discovered specimens in North America are all similar, R.M. Tryon found a phase in Asia that has longer setae that are orange-brown rather than white.[3]
