ANGIOSPERMAE 



685 



Flowers which are pentamerous in all five whorls 

 are found in the species of Rhododendron or Alpine 

 Rose, in Ledum palustre, and Andromeda ; all these 

 have a capsular fruit derived from the superior ovary. 

 Arctostaphylos Ura ursi is similar, but the fruit is a 

 drupe (Fig, 729). Pentamerous flowers with an inferior 

 ovary which becomes a berry are found in the genus 

 Vacoiwium (Fig. 730), V. vitis idea, Cowberry, V. 

 iiiyrtillus, Blaeberry. The remains of the calyx persist 

 on the summit of the fruit. A reduction of the number 

 of members of the whorls to four is met with in the 

 genus Erica with a superior ovary, many species being
