Studies of seed development and yield were conducted on three Aberystwyth varieties of timothy. The stages of seed development are described, as are their correlation with the external appearance of the head. Evidence is presented to support the suggestion that the latitude in the dale of harvest is greater than has hitherto been accepted. Population studies of seed crops have revealed that the abundant small heads (less than 4 cms. in length) contribute very little to the yield. The partition of the yield amongst the different inflorescence age‐groups is given for each variety and methods of judging crop ripeness are discussed.
