Linum perenne L.  (Syn: Adenolinum perenne (L.) Rchb. ) Blue Flax. CalPhotos. Jepson eFlora. SEINet Taxon. Golden Flora.

Weber & Wittmann (2012) distinguish between L. perenne and L. lewisii with the character of heterostyly in which some plants have styles longer than stamens and others with styles shorter than stamens. They apply homostyly to L. lewisii noting that the styles and stamens are approximately equal. My plants (Coll. No. 1383) consistently have styles longer than stamens. The key in Ackerfield (2015), based on plant structure and overall shape is not helpful because of the range of characters observed with this collection.
