For the study of the flowers one must select material at the time the male flowers are in bloom. In fig. 340 is represented a portion of the staminate spike of Carex laxiflora. As seen here each staminate flower consists of three stamens. These stamens arise in the axil of a bract. Figure 337 represents a portion of the pistillate spike of the same species at the time of flowering. The fact that the parts, or members, of the flower are in threes suggests that there may be some relationshi

The fact that the parts, or members, of the flower are in threes suggests that there may be some relationship be- tween the carex and the monoco- tyledons already studied, even though each flower has become so reduced in the number of its members. 508. In the bulrush (scirpus), another genus of this family, the flowers are perfect and complete (having all parts of the flower), with the parts in threes or some multiple of three, obvious resemblance to the monocotyledenous type.
