Telesonix (Saxifragaceae). T. jamesii was found to require light for germination (2nd Ed.). A new sample behaved differently and germ.40-70D(1/10)-40- 70D-40(3/10), 70D-40-70D-40-70D(5/13 in 2nd w), and none in 70L. The second sample may have undergone extensive DS and had the light requirement die away.
