Juno (lridaceae). This genus has been separated from Iris, and this separation is adopted here. Germination can extend over periods as long as 4 y and probably more. Treatment with GA-3 has not as yet initiated germination. J. magnifica germ. 40(30-100% in 10-12 w in six samples). The true leaf starts to form at 40, and development accelerates on shifting to 70. In samples where germination was below 100% germination occurred in further cycles.
