fruit ripens (l&^g. G5), A colored 

 calyx — i. e., not green — is said 

 to be Petaloid. Flowers with- 

 out petals and those of the Lily 

 Family usually have petaloid 

 sepals (Figs. G6, 70, 71). 



The Corolla is Polypet- 

 olous Avhen the petals are free 

 from each other (see Figs. 6G, 

 G8, 69, 73). In Gamopelalous 

 corollas there are all degrees of 

 cohesion from the complete 

 uuion (Fig. G7) of the Entire 

 limb to the almost free petals 

 of a Divided corolla (Fig. 58). 

 Petals often grow ujdou the calyx 

 (Fig. G8). Corollas are Regular 

 (Figs. 67, 69) or Irregular (Fig. 

 G6, and Fig. 58, p. 3. See also 

 the figures on p. 11 and j). 88b). 

 Common forms of regular co- 

 rollas are Rolate(Fig. 58), /Sa/re?--
