Mimulus (Scrophulariaceae). Light was required for some species. M. "Andean Nymph" germ. 70(1%)-40-70 and 40(34% in 5th w). M. "Calypso hybrids" germ. some in the 10th w at 70. M. primuloides germ. 70L(86% in 1-3w) and less and slower in 70D(22% in 1-7 w). This 70D sample was shifted to 70L in the 7th w whereupon 53% more germ. in 1- 3 w. M. primuloides also germ. 40-70L(90% in 6-8 d) and none in 40-70D. Seed DS 6 m at 70 germ. 70L(44% in 8-10 d), 70D(14% in 9-20 d), 40-70L(90% in 5-6 d), and 40- 70D(4%). The data indicates that there is some deterioration on DS.
