GONVOLVULAGE^-CONVOLVULUS 

 FAMILY 



Chiefly twining or trailing herbs, often with milky juice; alter- 

 nate leaves, and regular flowers with their parts in fives. The 

 calyx has five sepals imbricated in the bud; the corolla is five- 

 lobed, the lobes convolute or twisted in the bud. Stamens five, 

 inserted low down on the tube of the corolla, alternate with its 

 lobes. Fruit is a capsule, two to four-celled. In cultivation are 

 Morning-glory, Cypress Vine, Moon-flower, Great Bindweed, 

 and Sweet-potato. 



MORNING-GLORY 



Ipomaa hj/hrida. 



The garden race of Morning-glories are hybrids developed chiefly 

 from Ipomosa purpitrea and Ipomcea hederacea, both South American 

 species. A heart-shaped leaf indicates the purpurea strain predominant; 

 a three-Iobed leaf indicates hederacea. 



• Stem. — ^Twining from left to right, hairy, six to twelve feet high. 



Leaves. — Alternate, heart-shaped and entire, or three-lobed. 



Flowers. — Funnel-shaped, color range extending from violet and red- 

 purples to pure-white, variously striped and spotted. Peduncles three 

 to five-flowered. 



Calyx. — Five-parted, densely hairy below.

The Morning-glory is undoubtedly somewhat of a rascal when 

 given too free a hand in the garden. Possessed of tremendous 

 vitality it will sctnrry up a string or a pole at an astonishing rate
