Aureolaria (Scrophulariaceae). A. virginica germ. 40-70(30% in 5-24 d) and none at 70 using fresh seed. Light had no effect. Outdoor treatment led to 17% germination in March and April, but this is in effect a 40-70 treatment. Germination was much reduced by DS at either 70 or 40. The data were 70(0-5%) and 40-70(4- 10%). Percent germination is difficult to determine as the seed is small.
