Goldthread. Then it is Icclinically distinguished as a Thecaphore. When 

 there is a stalls, or lengtheued iuteruode of receptacle, directly under a 

 compound pistil, as in Stauleya and some other CruciferjE, it is called a 

 Gynophoke. When the stall: is developed below tlie stamens, as in most 

 species of Sileue (Fig. 356), it has been called an Anthopiiore or Gono- 

 PHORE. In Fig. 357 the torus is diluted above the calyx where it bears 

 the petals, then there is a long iuteruode (gonophorc) betM'een 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 aud 

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



beny, the Magnolia, etc. It is the receptacle in the Strawberry (Fig. 360), 

 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 Nclumbium, of the Water-Lily family, (he singu- 

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

 bears the small pistils immersed in separate cavities of its flat 

 upper surface (Fig. 362). 



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

 growth from it, hypogynom when underneath the pistil, as ia 

 Rue and the Orange (Fig. 363), and prrigj/nous -when adnate 

 to calyx-tube (as in Bucktliorn, Fig. 361, 365), and Cherry (Fig. 271), or
