Taxus (Taxaceae). T. baccata had some of the most extended germinations yet observed rivaling the Juno and Oncocyclus Iris. Seeds were WC for 7 d. Fresh seeds germ. 70-40-70(1%)-40-70(28% in 2nd w) and seeds DS 6 m at 70 germ. 70-40- 70(10%)-40-70-40-70(35% in 2nd w). Seeds started at 40 gave comparable patterns, and outdoor treatment gave equally extended germinations. Most of the seed was still firm and might germinate in further cycles.
