Studies on the biology of flowering of wild forms of the subgenus Glycine conducted in a controlled environment demonstrated a conspicuous drop-off of chasmogamic flowers within racemes (Skorupska et al., in press). For pollination, a small-sized insect was employed, viz., a wild bee Osmia rufa L. (0. bicornis L.). The selected wild bee of the family Mechali-chidae is described as the garden mason bee (W6jtowski, 1979).
