SUPPORTING EVIDENCE:

These species were added to Table 1 of the AOSA Rules for Testing Seeds in June 2001. The proposal for their addition to Table 1 did not include addition to Handbook 25. Catananche and the two species of Ipomoea are grown mainly as horticultural species and Clarkia bottae is a native species.
