Lithocarpus (Fagaceae). L. densiflorus v. echinoides germ. 70D(5/10 in 2- 12 w)-40(4/10 in 3rd w) and 40(4/7 in 12th w)-70D(3/7 in 2-12 d). Probably the rest would have germ. at the initial temperature if given longer times. L. densiflorus v. densiflorus germ. similarly in an even smaller sample. Seeds of both species were dead after 6 m DS at 70.
