Ver., Berlin, xxxviii, 1896.)—Hermann MuUer states that the white or reddish flowers of this species are not in a continuous plane, as in most Umbelliferae, but conspicuousness of the inflorescences is increased by the broad whitish involucral bracts. Besides protandrous hermaphrodite flowers, each umbel includes numerous marginal and central male ones, and as these usually mature late, they serve to pollinate tbo last developed stigmas of the hermaphrodite Fig. 157. Aslrantia major, L. (after Hrnn. MQIIer). (i) Male (lower at tlir beginning of anthesis; one stamen is erect, but its anther is still unripe ; the four other stamens are still tient down within the flower. (31 Male flower, with erect stamens, the antliers of two have tiehisced. (3) Hermaphrodite flower at the he;;;inning of anthesis: two stamens are erect, but their anthers have not dehisced ; the others are still bent down within the flower. The styles project from the flower, but their stig^mas are immature. (4) Her- maphrodite flower in the second (female) staf^e; the stamens have all fallen oft'; the styles have elongated and their stigmas are mature. «, stamen betit doun within the flower; a\ erect stamen; a'\ stan^cn with dehisced anther; ov, ovary; />, petal; s, sepal; j/, immature stigma; st\ mature stigma. The male flowers are distiibuted andromonoeciously or androdioeciously. Schulz says that the male flowers always exceed the hermaphrodi
