Anemone (Ranunculaceae). This genus divides into two groups. The .first group are early spring bloomers with hairless seed coats, multicycle germination patterns, and intolerance of OS. The second group are taller and bloom in summer and fall, the seed is embedded in cotton in a spherical cluster, and germination is largely D-70 with curious differences between DS seed and fresh seed. A. fasciculata germ 70(87% in 2-11 w), 40-70(95% in 4th w if cleaned), and 40- 70(84% in 3-9 w if not cleaned). The term cleaned as used here means that the dark brown wafer like covering was removed leaving the seeds in their light brown seed coat. Treatment with GA-3 on shifting from 40 to 70 did accelerate germination so that 90% germ. in 16-18 d, but the seedlings were weak and died, and in any event is of no practical importance. This species may well be the seed listed as
