Oxytropis (Fabiaceae). Oxytropis is typical of many Fabaceae. Some germination can be achieved without pretreatment, but such germination is generally slow and often extends over several cycles. if the seed is pretreated by grinding a hole throught the seed coat, germination is 100% in 1-3 d. The seeds are small so that the grinding is tedious and must be done carefully to avoid mechanical damage, but when done, it is dramatically effective. This was shown with 0. williamsii germ. 70(4/9 in 3-9d). All rotted -in 40-70.
