and by Young for Jefferson County. I found a large colony along the St. 

 Joseph River just west of the Elkhart County line. 



Nat. of Eu. ; now naturalized in N. A. from Newf. to Que., southw. to 

 Ga. and La. ; also in Calif, and B. C. 



2. Myosotis laxa Lehm. Map 1706. Frequent in the Mineral Springs 

 Bog in Porter County and also reported from Lake County by Pepoon as 

 occurring on the banks of a cold brook near Miller and on the margin of 

 the Little Calumet River. Probably restricted to these two counties. 



Newf., Ont., and Ind., southw. to Ga. and Tenn. ; also on the Pacific 

 coast from Calif, to B. C. ; and in Chile. 



3. Myosotis virginica (L.) BSP. Map 1707. An infrequent plant in the 

 northern and southern parts of the state. There are no records from the 

 area about Lake Michigan or from the central part of the Tipton Till Plain. 

 It is generally found in open places in noncalcareous soils. In the northern 

 part it is found in bare spots on the crests and slopes of black oak ridges ; 

 on lower ground, it is usually found in depressions in sandy soil in open 

 places in black and white oak woods, generally associated with Gaylussacia 

 baccata, Vaccinium vacillans, Houstonia longifolia, etc., and more rarely 

 found along railroads and roadsides. In the southern part of the state it is 

 most commonly found in white clay soil in fallow fields, where it is some- 

 times abundant, associated with Alopecurus caroliniana, Callitriche Aus- 

 tini, Arabis virginica, and Poa Chapmaniana. It is also found in bare 

 places in low, flat, post oak woods and in bare places on the crests of 

 black and white oak ridges. 



Maine, Ont. to Minn., southw. to Fla. and Tex. 



3a. Myosotis virginica var. macrosperma (Engelm.) Fern.* Map 1708. 

 This is a much larger plant than the species with larger calyx and seed 

 and is found in wet woods, associated with white elm, ash, and river birch ; 

 in drier woods with black and white oak ; also on wooded slopes.
