THE RECEPTACLE.

Goldthread. Then ft is technically distinguished as a Thecapuobe. When 

 there is a stalk, or lengthened internode of receptacle, directly under a 

 compound pistil, as in Stanleys and Borne other Crucifere, ii is called a 

 Gtnophobe. When the stalk is developed below the stamens, as in must 



species of Silenc (Fig. 350), it lias been called an AiJTHOPHORE or GOKO« 

 PHOES. Ill Fig. 357 the toniS is dilated above the Calyx where it hears 



the petals, then there is a bug mternode (gonophore) betweeu it and the 



stamens; then a shorter one (gynophore) between these and the pistil. 



324. A Carpophore is a prolongation of receptacle or axis between the 

 carpels and bearing them. Umbelliferous plants and Geranium (Fig. 358, 

 359) afford characteristic examples. 



325. Flowers with very numerous simple pistils generally have the re- 

 ceptacle enlarged so as to give them room ; sometimes becoming broad and 

 ilat, as in the Flowering Raspberry, sometimes elongated, as in the Black-

berry, the Magnolia, etc. It is the receptacle in the Strawberry (Fig. 3G0), 

 much enlarged and pulpy when ripe, which forms the eatable part of the 

 fruit, and bears the small seed-like pistils on its surface. In the Rose 

 (Fig. 361), instead of being convex or conical, the receptacle is deeply 

 concave, or urn-shaped. Indeed, a Rose-hip may be likened to a straw- 

 berry turned inside out, like the finger of a glove reversed, 

 and the whole covered by the adherent tube of the calyx. 

 The calyx remains beneath in the strawberry. 



326. In Nelumbium, of the Water-Lily family, the singu- 

 lar and greatly enlarged receptacle is shaped like a top, and 

 bears the small pistils immersed in separate cavities of its Ilat 

 upper surface (Fig. 362). 



327. A Disk is an enlarged low receptacle or an out- 

 growth from it, hypogt/nous when underneath the pistil, as in 

 Rue and the Orange i Fig. 363), and pertgynout Trheo adnate 

 to calyx-tube (as in Buckthorn, Fig. 301, 305), and Cherry (Kg- •j;i) j r
