212 THE FLOWER. 



while the pistils line the walls of the cavity, the base or centre 

 of this cavity answering to the apex of the strawberry. 



390. Sometimes internodes are lengthened between certain 

 members. In Schizandra, the receptacle, barely oblong in blos- 

 som, lengthens greatly in fruiting, so as to scatter the carpels 

 on a long filiform axis. 



391. In many Gentians, in Stanleya and Warea among 

 Cruciferse, and in most species of Cleome, the internode of the 



receptacle between stamens 

 and pistil is developed into 

 a long stalk to the latter. 

 G-ynandropsis (Fig. 409) is 

 like its near relative, Cleome, 

 except that this very long stalk 

 has the lower part of the 

 stamens adnate to it : the in- 

 ternode between the corolla 

 and calyx is broad and slightly 

 elevated (or in Cleome, &c., 

 narrower and longer) ; and 



408 409 8O the several floral circles 



are as it were spaced apart by this unusual development of 

 receptacular internodes. In Silene (Fig. 408) and many other 

 plants of the Pink family, an internode between the calyx and 

 corolla is prolonged into a stalk or Stipe. 1 



1 STIPE is the general name of a stalk formed by the receptacle or some 

 part of it, or by a carpel. To distinguish its particular nature in any case, 

 the following terms are more or less employed : 



THECAPHORE, for a stipe which belongs to a simple pistil itself (where 

 it is homologous with a petiole), and is no part of the receptacle, as in Coptis 

 or Goldthread. 



GYNOPHORE, where the stipe is an internode of receptacle next below the 

 gynceciuin, as the pod-stalk in some Cruciferae, Cleome, and Gynandropsis. 



GONOPHORE, when it elevates both stamens and pistil, as it seemingly 

 does in the lower stipe of Gynandropsis, Fig. 409. 



ANTHOPHORE, when the stipe is a developed internode between the 

 calyx and corolla, as in the Pink family, Fig. 408. 



GYNOBASE is a term properly applied to a short and comparatively broad 

 portion of receptacle on which the gynoecium rests, as in Rue and Orange 

 (Fig. 414), Houndstongue, Sage, &c. This may extend up between the car- 

 pels and pass into, or the upper part become a 



CARPOPHORE, a name properly applied to a portion of receptacle which 

 is prolonged between the carpels as a central axis, as in Geranium (Fig. 

 411) and many Umbelliferae, Fig. 412.
