. Introduction to structural and systematic botany, and vegetable physiology. Botany. 488. Unusual States of the Receptacle. The receptacle (421) is commonly small, short, and inconspicuous, being merely the extrem- ity of the flower-stalk upon which the sev- eral organs are inserted (Fig. 343). Some- times, however, it is remarkably enlarged or elongated. A striking instance of an en- larged receptacle is found in Nelumbium, where it is dilated into a large top-shaped body, nearly enclosing the pistils in sep- arate cavities (Fig. 427). "Whenever the pistils of a flower are very numerous, the receptacle is more or less enlarged for their insertion, as in Magnolia, the Raspberry and Blackberry, &c. In the Strawberry the enlarged and conical receptacle (Fig. 428), bearing the pistils on its surface, becomes the edible portion in fruit. In the Rose (Fig. 429) the receptacle is deeply concave, instead of convex, being urn- shaped, invested by the adnate tube of the calyx, and bearing the petals and stamens on its bor- der and the numerous pistils on its whole hol- low surface (Fig. 429). It is much the same in Calycanthus (Fig. 814 - 819). In Geranium,and many allied plants, the receptacle is prolonged between the ovaries, and coheres with their styles (Fig. 430); these, however, separating at maturity (Fig. 431). In Umbelliferous plants a similar but more slender prolongation of the receptacle is extended upwards between the contiguous faces of the two united ovaries which form the fruit FIG. 427.
