|discussion=<p>North American material of Stellaria ruscifolia is variable but tends to be more compact and smaller than that from the Russian Far East. It is referable to subsp. aleutica. It appears to be a relative of S. longipes, and some forms of the latter with wider leaves (S. crassipes) are very similar but do not have the coriaceous, more or less prickly leaves.</p>
