Verbena urticaefolia 

 var. leiocarpa Perry & Fern. 



Stems densely soft-pubescent, the hairs mostly 0.75-1 mm long; fruiting 

 calyx generally 4-5 mm long; seed about 2.5 mm long; leaves thick, rigidly 



ascending, mostly ovate, densely soft-pubescent 5. V. stricta. 



Bracts longer than the flowers; spikes thick, dense; plants usually spreading, 

 never erect 6. V. bracteata. 



1. Verbena canadensis (L.) Britt. Rose Verbena. Map 1718. This 

 species has been reported from 6 counties. It has long been cultivated and 

 much used for planting on graves in cemeteries whence it doubtless fre- 

 quently escapes. I have found this species growing on the slope of a creek 

 bank below an old cemetery in which I found it to be common. It has 

 abundantly escaped from cemeteries in Jefferson County and it was found 

 by Chas. M. Ek as an escape from a cemetery in Howard County. I believe 

 it is an escape in Indiana.

2. Verbena urticaefolia L. White Vervain. Map 1719. This species 

 doubtless occurs in every county. It is found in almost all kinds of soil 

 except in very wet places ; it is generally found in open woods, along logging 

 roads in thick woodland, in fallow fields and waste places, and along road- 

 sides and railroads. All of the species of Indiana vervains are extremely 

 variable, especially in the leaf margins and color of flowers. Evidence of 

 hybridization is frequent. I have a specimen with pink flowers from Wells 

 County.

2a. Verbena urticaefolia var. leiocarpa Perry & Fern. (Rhodora 38: 

 441-443. 1936.) Map 1720. This variety has the habitat of the species and 

 is about as widely distributed in Indiana. 



Fernald gives the range as from Conn, to S. C. 



3. Verbena hastata L. Blue Vervain. Map 1721. This species is found 

 throughout the state. It prefers a moist soil in the open. It is frequent to 

 common in the lake area in moist places about lakes, in marshes, moist, 

 sandy prairie habitats, interdunal flats, low, open woods, roadside ditches,
