Gentianella (Gentianaceae). The splitting out of this genus and Gentianopsis from Gentiana has not been helpful as species have been shuttled around between the three genera. Light and GA-3 need to be tried. G. turkestanorum sown outdoors in January germ. well in April. A second sample germ. 70 GA-3(25% in 4-6 w) and none in 700 or 70L.
