SECT. I* THE FLOWER. QJ 



as to exhibit a slight resemblance to a butterfly, 

 in which case the flower is said to be papilionace- 

 ous, and is exemplified in the Pea and Bean (P/. IV. 

 Fig. 10.) ; the petals of which, and of all similar 

 flowers, are so peculiar in their form or position as 

 to have received distinct appellations. The upper 

 petal, which is generally large with an erect border, 

 is denominated the standard. The lower petal, 

 which is situated opposite to the standard, and hol- 

 lowed out in the form of a boat, is denominated the 

 keel. And the two remaining petals, which are 

 situated in an opposite position, one on each side of 

 the keel, are denominated the wings. 



If the corolla is inserted in the receptacle, that is Insertion, 

 underneath the ovary, as in Convolvulus, it is said 

 to be Hy-pogynous ; if it is inserted in the calyx, or 

 integument surrounding the ovary, as in the genus 

 Ribes and many others, it is said to be Perigy- 

 nous ; and if it is inserted upon the ovary, as in the 

 genus Scabiosa, it is said to be Epigynous. 



If it is longer than the calyx it is said to be large, 

 as in Convolvulus sepium ; if it is shorter than the 

 calyx it is said to be small, as in Fragraria vesca ; 

 and if it is of the same length with the calyx it 

 is said to be of a moderate size, as in Fragraria 

 sterilis. 



If the corolla falls before the stamina, or organs 

 which it immediately invests, it is said to be 

 caducous or fugacious, as in Cistu* ledifolius ; if it 

 falls with the stamina it is said to be deciduous, as
