Linum catharticum N. Martineau

A European species, locally naturalized usually in calcareous habitats where it is associated with many interesting native calciphiles, such as Iris lacustris, Carex crawei, C. garberi, Sisyrinchium mucronatum, Trichophorum cespitosum, and Primula mistassinica.

First collected in Michigan in 1940 along a grassy roadside in Keweenaw Co. This is a delicate little annual, rarely if ever over 2 dm tall. Its small white (yellow-eyed) flowers and sparse opposite leaves (dense on basal offshoots) readily distinguish it.
