Verbena bracteata Lag. & Rodr. 



and even in the moist, marl border of a lake. It is less frequent south of 

 the lake area and is found in moist places along roadsides, in clearings, 

 fallow fields and low open woods. 



I have specimens with white flowers from La Porte and Warrick 

 Counties.

3a. X Verbena Engelmannii Moldenke. (Verbena hastata X urticae- 

 folia.) I collected this hybrid in a prairie habitat along the roadside 

 2 miles south of Circleville, Clinton County and in Warrick County. 



4. Verbena simplex Lehm. (Verbena, angustifolia Michx.) Narrow- 

 leaf Vervain. Map 1722. This species has been reported from 9 counties 

 and doubtless is found infrequently throughout the state. It prefers dry 

 and rather sandy soil in the open, although I have one specimen from a 

 dried-up slough. It is generally found along roadsides and railroads, in 

 fallow fields, and on open, washed, wooded slopes. It is usually found 

 associated with Verbena stricta.

4a. X Verbena moechina Moldenke. This is the name recently proposed 

 for the commonly occurring natural hybrid between Verbena simplex and 

 Verbena stricta. I have it from Daviess, Harrison, Marion, Orange, and 

 Washington Counties. 



5. Verbena stricta Vent. Hoary Vervain. Map 1723. Found through- 

 out the state although there are no records or specimens from some of the 

 central counties. It is almost exclusively found in very sandy soil along 

 roadsides, rarely along railroads, in sandy pastures, waste places, and 

 fallow fields. I believe it has migrated into northern Indiana, and were 

 it not for the fact that Michaux, 1 who spent August 18, 1795 botanizing 

 along the Wabash River in the vicinity of Vincennes, reported finding
