182 MORNING GLORY FAMILY 



many broad, long-stalked leaves that open like a book. 

 The heavy stems often have the singular habit of growing 

 straight from the dunes to the water's edge, and lie in 

 parallel lines across the sand. It is also occasionally found 

 in sandy soil in the interior. 



From spring to fall, in many locations, are found the 

 trailing brewerias — Breweria grandifiora, whose beauti- 

 ful light blue flowers well merit the specific name, and 

 several smaller species with slender prostrate stems, and 

 little white morning glory flowers, only half an inch to 

 an inch across. 



Silky plants of Evolvulus, with small and extremely 

 delicate flowers, and of spreading growth, bloom during 

 spring and summer. Like the brewerias, the flowers are 

 distinguished from others of this family in having two 

 styles, instead of one. 



The cultivated sweet potato is a well-known morning 

 glory, Ipomoea Batatas. And parasitic dodders of the 

 genus Cuscuta, known both as love-vine and as hell-weed, 

 are aberrant members of the family.
