ADHESIONS BETWEEN THE CALYX AND OVARY. 



the ovary, o, becomes half-inferior, the calyx being half-superior. These 

 adhesions between the calyx and the ovary will be found to be of 

 importance, as determining the epigynous and perigynous (tvl, upon or 



above, and 



pistil) condition of the stamens. 



Cases of adhesion between the ovary and the calyx, as occurin the Apple, 

 Pear, Gooseberry, and Fuchsia (fig. 399), must not be confounded with 

 cases such as the Eose (fig. 270), where the tube of the calyx becomes 

 enlarged and hollowed so as to cover the carpels. In the former 

 case, a transverse section (fig. 399) shows one or several closed locula-

 or loculi, with the ovules attached to their internal angles. Fig. 384 shows the same section more 

 highly magnified. The upper half, 1, has been cut vertically, to show the ovules, g, arranged in 

 a row in each loculament. The calyx, incorporated with the ovary below, is prolonged above it 

 in the form of a tube, t, and divides at its summit into four segments, 1 1. p, Petals inserted on
