MORNING-GLORY FAMILY CONVOLVULACEAE 



The family is represented in California chiefly by vines. It contains one of 

 our most highly prized vegetables, the sweet potato, Ipomoea Batatas. What is 

 generally considered the worst weed in the state is the Field Morning Glory, Con- 

 volvulus arvensis. It provides also the purgative medicines, Jalap and Scammony. 

 The annual Morning Glory, Ipomoea purpurea, of many gorgeous colors, is a 

 favorite in the gardens and occassionally found in California as an escape.

Cressa cretica 



Covering thousands of acres of valley alkali lands. A valuable pasture plant, 

 light-gray, hairy leaves on short, erect stems, not twining. Flowers whitish, small. 



1364. Dodder Cuscuta 



Our worst enemy of alfalfa, sometimes seriously interfering with the crops of 

 hay. Well known by its golden-threaded, climbing leafless stems which later bear 

 numerous clusters of whitish flowers. There are many species both native and 

 introduced. They are all parasitic on other plants. Some of the species grow 

 on a large number of plants not closely related, while others confine themselves to 

 a single host plant. 



The Marsh Dodder, Cuscuta salina, is unusually striking with its great masses 

 of gold in late spring in the salt marshes of the Bay region. Particularly abund- 

 ant after leaving the boat at Sausalito. Other species may be found in the valleys, 

 coast mountains and the deserts, and not uncommon in the Sierras. 



1365. Dichondra repens Introduced in several places 



in the Bay region.
