PlG. 305. A common type of the Ranales, Ranunculus repens: A, habit of the plant. B, early stage of flowering, the stamens clustered about the stigmas. C, late stage of flowering, nearly all the stamens bent over towards the petals, having discharged their spores. D, petal with nectar gland at base. E, fruit consisting bf numerous spirally-arranged akenes. hood (Aconitum), may apple (Podophyllum), magnolia, tulip tree (Liriodendron), Sassafras, spice bush (Benzoin), etc. In this order we have again reached the point, just as in the monocoty- ledons (see Liliales), where the flowers are more usually solitary and conspicuous, owing to the development of large, showy perianths. While the perianth is more differentiated than in the lilies it is noteworthy in the majority of the forms that the flower has not reached the statie where the calyx is clearly separable from the corolla. The flowers are very simple, as is indicated by the regular and hypogynous arrangement of the parts (Fig,.
