668 Malvaceae Callirhoe 



following species from which it has not been separated in our manuals. 

 No doubt search will reveal its presence in our area in many places. Its 

 general distribution has not yet been studied. 



Nat. of Eu. ; N. J., Pa., Mich., N. Dak., and westw. 



3. Malva NEGLECTA Wallr. (Malva rotundifolia of authors.) Map 

 1392. A frequent weed mostly about dwellings and in waste places in 

 all parts of the state. When once established it soon becomes abundant 

 and a pest, especially when it enters barnyards and cultivated grounds. 



Nat. of Eurasia and widely naturalized throughout all but the colder 

 parts of N. A. 



4. Malva moschata L. Musk Mallow. Map 1393. There are three 

 reports from Indiana. There is a pink and a white form. My specimen 

 is the white form and was collected along a roadside 5 miles north of 

 Goshen in Elkhart County. 



Nat. of Eu. ; Newf. to B. C, southw. to N. J., Va., and Wis. 



4992A. CALLlRHOE Nutt. 



1. Callirhoe triangulata (Leavenw.) Gray. Clustered Poppy-mallow. 

 Map 1394. Indiana is included in the range of this species in Gray, Man., 

 ed. 7 and in Britton and Brown, Illus. Flora, ed. 2. There were, how- 

 ever, no specimens in the Gray Herbarium or in the herbarium of the 

 New York Botanical Garden until I sent them specimens in 1933. There 

 are no other reports. In July, 1933, Scott McCoy found it plentiful in 

 sandy soil along the C. E. & I. Railroad about a mile north of Oaktown, 

 Knox County. I visited this place in August, 1933, and found the species 

 well established at three places. An attempt to dig some plants convinced 

 me that it has been there for some time and is doubtless established.
