It is generally found in dry open woods, clearings, fallow fields, and 

 along roadsides.

2. Blephilia hirsuta (Pursh) Benth. Map 1770. This is strictly a wood- 

 land species and is very rarely found elsewhere. Found throughout the 

 state although we have no records for the northwestern part of the state 

 west of La Porte County. It is generally found in rich woods in deep leaf 

 mold. It is notable that the foliage is eaten by insects to such an extent 

 that whole specimens are usually difficult to obtain.

7302. HEDEOMA Pers. 



Leaves petiolate, ovate to linear-lanceolate, mostly 3-12 mm wide, sometimes up to 

 20 mm wide, at least the wider ones serrate; bracts mostly shorter than the 

 pedicels, obtuse; teeth of the upper lip generally triangular, acute; seed smooth, 

 broadly ovate, generally slightly less than 1 mm long 1. H. pulegioides. 



Leaves sessile or the lowest petiolate, linear, 1.5-3 mm wide, rarely wider, entire; 

 bracts linear-subulate, generally longer than the pedicels; upper teeth of calyx 

 generally subulate; seed oblong, generally 1-1.3 mm long, surface reticulate under 

 a magnification of 20 diameters 2. H. hispida. 



1. Hedeoma pulegioides (L.) Pers. AMERICAN PENNYROYAL. Map 

 1771. Frequent to common in all parts of the state and probably found 

 in every county. This species prefers dry soil and is found in dry, open 

 woods of all kinds, sometimes in low woods, fallow fields and along road- 

 sides and railroads. It usually flowers about two weeks or more later than 

 the next species. 



N. S., Que., and N. Dak., southw. to Fla., Ala. and Ark. 



2. Hedeoma hispida Pursh. PvOUGH Pennyroyal. Map 1772. Infrequent 

 in Indiana. The plant is inconspicuous and no doubt is more common than 

 our map indicates. It is found only in dry, usually very sandy soil, in 

 rather acid habitats in open black oak woods, open wooded crests of ridges,
