GS XC. CONVOLVULACE^E (BAKER AND RENDLE). [Evolvulus, 



shape of the leaf, relative length of the peduncle and general hairiness. Sckwein- 

 furth (followed hy Hallier and Hiern) recognises two varieties, procumbens {JE. 

 alsinoides, Linn.) and erectus (JE. linifolius, Linn.), but, as I find it impossible to 

 say to which form many of the specimens belong, I prefer to consider them all 

 under the species. Some specimens credited to var. erectus are young plants, which 

 perhaps become procumbent later. A. B. R. 



Also in South Africa, and widely distributed in the Tropics.

Dioecious, flowers small, 4-5-merous. Sepals in the male flower sub- 

 equal, in the female flower 2 or 3 outer much larger than the inner, accre- 

 scent. Corolla minute, several times longer than the calyx in the male 

 flower, slightly protruding beyond it in the female, funnel-shaped, 4-5- 

 lobed. Filaments glabrous ; anthers oblong, exsertecl, aborted in the 

 female flower. Ovary glabrous, 2-celled, 4-ovuled, smaller and sterile in 

 the male ; styles 2 ; stigmas somewhat horseshoe-shaped, with a pair of 

 irregularly crenately lobecl branches. Capsule concealed by the two 

 large membranous, orbicular, veined, accrescent outer sepals, 4-valved, 

 2-celled. Seeds 1-4, trigonous, glabrous. — Much-branched shrubs ; 

 some branches elongated, spreading, erect, or climbing, others short 

 and tuberculiform ; leaves alternate along the young elongated shoots, 

 or fascicled on the dwarf shoots, small, cuneate-spathulate, subsessile. 

 Flowers axillary on the dwarf shoots, subsessile in the male, on slender 

 stalks in the female. 



Species 4 ; endemic. 

 Flowers tetramerous. 



Inner pair of sepals of female flower minute, not 

 accrescent.
