Cerastium beeringianum Cham. & Schltdl.[FNA5, HC, HC2]
alpine chickweed

Publication: Linnaea. 1: 62. 1826.

Origin: Native

selected vouchers: WTU

Notes: Rare in WA; difficult to distinguish from dwarf mountain forms of C. arvense.

FNA5: "Cerastium beeringianum is distinguished from C. alpinum by the absence of the long, silvery, flexuous, translucent, glistening hairs of that species. Cerastium beeringianum\\\\\\'s pubescence consists of straight, strigose, multicellular, somewhat fuscous hairs of several lengths, many of those in the mid and distal stem and inflorescence being glandular and viscid. The nodes and the leaves, at least in the mid and distal stem, typically have long, strigose, eglandular, fuscous hairs; those on the adaxial surface of the leaf being appressed, and those on the nodes retrorse. However, plants from the many small, isolated populations on the mountains of western North America show a great deal of variation. Some of these populations tend to be subglabrous, lacking most of the long hairs normally found on this species. Others are small, delicate plants with slender divaricate pedicels and smaller capsules and seeds. Though names have been given to several of these variants, they frequently intergrade, and much of the variation is greatly influenced by the environment."
