Abstract
The main axis of dormant brodiaea corms ( Triteleia laxa) harvested from the field in the summer comprises a leaf sheath, two leaf primordia, and a vegetative meristem. Floral induction, as indicated by initiation of bracts on the flanks of the apical meristem, occurs after corm dormancy is broken. The bracts enlarge and enclose the reproductive dome, which then divides to form floral primordia of different ages. The daughter corm, which forms from the basal portion of the stem, starts to enlarge early in the growing season. Unlike many other geophytes, there is little competition, in brodiaea, for assimilates between the vegetative propagules (daughter corm and cormels) and the developing inflorescence.
