ORGANOGRAPHY AND GLOSSOLOGY. 



The compound style is improperly said to be simple (st. simplex), when wholly 

 undivided ; it is bi- tri-jid, &c., when the component styles cohere beyond the 

 middle ; bi- partite, &c., when they do not cohere to the middle. The styles of each 

 carpel rarely bifurcate once or. twice ; when they do, they are double or quadruple in 

 number to the carpels (Euphorbia, fig. 406). 



The style is terminal (st. terminalis), when it springs from the top of the ovary 

 (Apricot, fig. 411) ; lateral, when it springs more or less from the 

 side of the carpel, the top of which appears bent downwards (Straw- 

 berry, fig. 407) ; basilar (st. basilaris), when the top of the ovary is

bent down to a level with its base (Alchemilla, fig. 408). When there are many 

 ovaries, with confluent basilar styles, the style is said to be gynobasic (st. gynobasicus, 

 Comfrey, fig. 409), and the dilated base 

 of this composite style, extending below 

 the ovaries and surface of the re- 

 ceptacle, has been called a gynobase

(yynobasis). The gynobase is sometimes prolonged into a gynophore (Sage, fig. 410, o) ; 

 but a gynophore proper must not be confounded with the gynobase ; the gynobase 

 belongs to the styles, that is, to the carpels ; the gynophore proper belongs to the 

 axis itself, of which it is the termination. 1 



The style is a portion of the carpellary leaf, contracted into a sort of longi- 

 tudinal tube, filled with a moist and loose parenchyma, named conducting tissue 



Except under the view that the placenta are productions of the axis. ED.
