Allium (Liliaceae). This genus showed much diversity. Germination patterns ranged from simple D-70 in A. pulchellum like A. karataviense gave some of the most extended germination observed. Germination occurred at both 70 and 40 and in comparable overall percentages for fresh seed or DS seed. Some of the experiments were closed prematurely. The seed was still firm arid, in retrospect, would probably have given further germination. The data is given in full. Fresh seed germ. 70-40-70-40-70 none and 40-70(5%)-40(15%)-70(5%). Seed DS 6 m at 70 germ. 70-40-70-40(6%)-70-40- 70(6%) and 40-70-40-70-40(15%)-70(15%). Seed DS 6 m at 40 germ. 70-40-70- 40(4%)-70(4%)-40(4%-70(20%) and 40-70(5%)-40-70-40(20%)-70(25%).
