SUMMARY 1. The number of flowers per raceme is slightly greater in Common than in giant sainfoin. 2. Little more than half the flowers set seed under conditions of open pollination. 3. When the flowers were protected and left untouched the self‐fertility was found to be 0.98%. When the flowers were artificially self‐pollinated by tripping the self‐fertility was significantly higher, being 5.11% 4. Seedlings grown from selfed seed showed poor establishment and reduced vigour. 5. Evidence is brought forward which suggests that the phenomenon of seeding year flowering in common sainfoin cannot be due to the fertilization of the parent plants by pollen from giant sainfoin.
