 glabra, at sub lente pilis longiusculis tenuibus subappressis undique 

 conspersa. Radices partim breves, carnosae et subfusiformes, 

 partim multo longiores et tenuiter fibrosae. Folia radicalia longi- 

 petiolata, subcordato-reniformia, i>^-2 cm. longa, 2-3 cm. lata, 

 leviter 7-crenata, caulina sessilia, 3-partita. Corolla i cm. lata;

An interesting and strongly characterized member of the 

 R. ahortivus alliance, known only as collected in extreme southern 

 Indiana, 20 April, 1913, by Air. Charles C. Deam, where it inhabites 

 wooded knolls, under Pinus Virginiana and Ouercus alba; the 

 special locality two miles west of New Albany. The flowers are 

 not as large as those of R. Harveyi, yet much larger than those of 

 the rest of its allies of this group. The foliage remarkably simulates 

 that of Linaria Cymbalaria.
