CLITORIA 



Tropical evergreen leguminous climbers with axillary, 

 pea-like flowers. There are about thirty species, wide- 

 spread over the tropics, but few of them are in cultivation. 

 Of these C. Ternatea is the best known, its flowers azure-

 lections. Clitorias are best grown from seeds, in a com- 

 post of peat, loam, and sand.

 and tubular campanulate flowers, 3 inches long, at first 

 greenish, but changing to dark purple. The growth is so 

 rapid that the plant is frequently employed for covering 

 large trellises and wall areas out of doors and in large 

 conservatories. The amount of growth a plant is capable 

 of making in one season is prodigious. The variety varie- 

 gata has golden variegated leaves ; this is propagated by 

 cuttings of the young shoots taken in spring. In the 

 United States C. scandens is popularly known as the Cup 

 and Saucer Vine. It is largely grown out of doors there.

 which are of considerable beauty. The climbers should
