THE INDIANA WEED BOOK. 



hock, cotton plant and okra are familiar or cultivated forms. The 

 rose mallows which grow wild along the borders of marshes and 

 streams produce some of the largest and most handsome of our 

 wild blossoms. The most common one of these is the halberd- 

 leaved rose mallow, 4-8 feet high and having the upper leaves 

 hastate, the large bell-shaped flower pink with a purplish base and 

 the fruit-pod surrounded by the bladder-like inflated calyx. Only 

 a dozen species of the mallow family grow wild in the State, three 

 of which are weeds.

 ing Charley. Cheeses. (P. I. 2.) 



Stem branched at the base and 

 spreading from a deep root, 4-12 

 inches long ; leaves long-stalked, 

 rounded or kidney-form, obscurely 

 5-9-lobed, the edges scalloped. 

 Flowers clustered in the axils, pale 

 blue, inch broad; petals oblong, 

 notched at the end, twice the length 

 of sepals ; ovaries about 15, rounded

 places in cities and towns. May- 

 Nov. Children often eat the 

 rig. 62. (After ciark.) disk-shaped little fruit bodies, 



calling them "cheeses/' whence the following lines: 



"The sitting down when school was o'er 

 Upon the threshold of the door, 

 Picking from mallows, sport to please, 

 The crumpled seed we call a cheese." 



Like other weeds which flourish best in compact or trodden ground 

 this mallow has a long and tapering root. Remedies: pulling or 

 deep cutting with hoe or spud in lawns and yards ; thorough culti-
