. Elementary botany . Botany. DICOTYLEDONS. Fig, 132.—Staniinate flower of Hazel inserted on bract (6r), with which two prophylls (pr) are fused. Fig. t33.—Diagram of ditto. sists solely of four stamens, which are attached to the bract in place of being on a flower-stalk in the axil of that bract. Each stamen is halved almost to the base of its filament, so that at first sight there appear to be eight stamens, each of which possesses only half a complete anther. The anther is crowned by a tuft of hairs. The bud of the dwarf branch (fig. 134) which produces the carpellary in- florescence is often , loosely described as being the in- florescence. The bud is really the commencement of a foliaged branch which terminates in an inflorescence; but the foliage-leaves do not unfold till after the flowering is over. On the axis of this bud the most external and lowest leaves are two prophylls; then succeed three to four pairs of scale - Uke stipules (sc), and' within these two to four foliage-leaves.' Thus so far the bud is Uke a vegetative bud; but above these foliage-leaves follows the true inflorescence. The carpellary inflorescence consists of four to eight spirally-placed bracts (i>r) with axillary flowers, which are borne on a shortened axis. In the axil of each bract (fig. 135) there stand the buds of two carpellary flowers, so that the whole inflores- cence possesses eight to' sixteen flower-buds. But only a few of the flower - buds develop into mature flowers. Each carpellary flower has a minute, indistinctly lobed, green Fig. 134.—Vertical section of perianth (pe), which is inserted on the Xeity^Ml^sclT'"" " ".
