CALYCIFLOR.E 255 



heart-shaped, the lobes five to seven, broad, deep, 

 angular, wavy, coarsely toothed, the middle one the 

 longest, rough both sides, with hard points. 



The flowers are unisexual, the plant being dioecious, 

 the male flowers being in stalked racemes or corymb- 

 ose cymes, several together, pale yellow, the corolla 

 broadly bell-shaped ; the females, in umbels, are 

 smaller, two together, wheel-shaped, the ovary 

 globular, smooth, with a two-cleft stigma. The 

 corolla is hairy, the calyx in the female flowers half 

 as long. The berries are red when ripe, with flat, 

 nearly round seeds. 



The flowers bloom from May to September. The 

 plant is a herbaceous perennial, and is a climbing 

 plant, 5 to 10 ft. in height. 



The honey lies concealed by the disc or recepta- 

 cular tube above the ovary in the female. In the 

 male flowers it can be reached between the stamens. 

 The corolla is gamopetalous, which is unusual in the 

 Calycifloras. The stamens are fixed on the lower 

 part of the corolla and the honey is protected by the 

 base of the stalk. The stamens are wavy and 

 peculiar in shape, and dust an insect both sides and 

 above, and the anthers being gummy the pollen readily 

 sticks. Being dioecious, insects must pollinate 

 the plant, and where it grows it usually sets seed, 

 so that this seems to be generally the case. But, 

 as has been said, the insects suited to it are rare in 

 some parts, and where they are absent so is the 

 White Bryony.
