Synnotia (Iridaceae). Their is some indication that 3 m in 70L before shifting to 40 gives better germination than either 40 direct or 70D-40. Also DS for 1 y improved germination in the one species in which it was tried. More work is needed to confirm these provisional conclusions. S. variegata DS 6 m germ. 70D-40{30% in 5-7 w) and 70L-40(60% in 5-7 w). A second sample failed to germinate in either of the above two treatments. S. variegata kamphiae DS 6 m germ. 70D-40(55% in 5-7 w) and 70L-40(4/4 in 7th w).
