Discussion
Linum compactum is generally low-growing, much branched, and bushy; its flowers are smaller than those of L. rigidum. Linum compactum is found on the high plains in open areas. C. M. Rogers (1984) suggested that it might be closely related to L. australe, which differs in being more slender with more open habit and of pine forest habitats.
