tube of the calyx ; Ex. Rose : or of tooth-like, hypogynous 

 (358) processes ; Ex. Gesnera, Cruciferse. 



389. When a fleshy substance occupies the centre of a 

 flower, and bears a single row of carpels, it is called the 

 gynobase ; Ex. Lamium, Ochna, Geranium, &c. If this sub- 

 stance bears a greater number of carpels than can be arranged 

 in one row, it is called the torus or receptacle; Ex. Straw- 

 berry, Nelumbium. 



390. It is certain that the disk is a non-developement of an 

 inner row or rows of stamens, as is proved by the Moutan 

 Paeony. 



391. The receptacle or torus is the growing point (164) 

 of the flower-bud in a state of enlargement. 



392. The disk is one of the parts which Linnsean botanists 

 call nectary. 



XIII. FEMALE ORGANS. 



393. The organ which occupies the centre of a flower, 

 within the stamens and disk, if the latter be present, is called 

 the pistil. 



394. It is the female apparatus of flowering plants, or the 

 gynoeceum 241 . 



395. It is distinguished into three parts ; viz. the ovary, the 

 style, and the stigma. 241 



396. The OVARY is a hollow case, enclosing ovules 

 (445). It contains one or more cavities, called 

 cells. 



397. The STIGMA is the upper extremity of the 

 pistil. 



398. The STYLE is the part that connects the ovary 

 and stigma. 



399. The style is frequently absent, and is no 

 more essential to a pistil than a petiole to a leaf, 

 or a filament to an anther. 



400. Sometimes the style is thin, flat, and membranous, 

 and assumes the form of a petal, as in Iris. 



401. The style is either articulated with the ovary, or con- 

 tinuous with it. It usually proceeds directly from the apex 

 of the ovary ; but in some cases arises from the side, or even 

 the base of that organ ; Ex. Alchemilla, Chrysobalanacese.
