fbb REPORT OF STATE GEOLOGIST. 



B. steicta Andrz. 



Keported only from Putnam County, by D. T. MacDougal. The 

 specimen seems to be B. stricta, but range probabilities are so 

 strongly against it that it is somewhat doubtfully included. 



IODANTHUS Torr. and Gr. 



I. pinnatifidus (Michx.) Steud. Purple or False Rocket. 

 (Thelypodium pinnatifidum S. Wats.) 

 Frequent in the southern part of the State on rich hillsides or 

 in low, rich woods. 



It flowers in May and June, although most abundantly in May.

RORIPA Scop. 



R. sinuata (Nutt.) A. S. Hitchcock. Spreading Yellow Cress. 

 (Nasturtium sinuatum Nutt.) 

 A specimen in the Herbarium of DePauw University, collected 

 by Dr. MacDougal, is referred to this species. The range of the 

 form is much to the west of Indiana, and it is doubtful whether 

 it is more than an accidental migrant. It is reported from no 

 other station than that in Putnam County. 



R. obtusa (Nutt.) Britton. Blunt-leaved Yellow Cress. 



(Nasturtium obtusum Nutt.) 

 Reported from Tippecanoe County by Professor Hussey, and 

 from Clark by Baird and Taylor. The Tippecanoe County refer- 

 ence is verified by herbarium specimens. Low grounds in rich 

 soil. 



R. palustris (L.) Bess. Marsh Cress. Yellow Water Cress. 

 (Nasturtium palustre DC.) 



Largely distributed throughout the State, growing in low 

 ground, swamps or shallow water.* Its flowering season extends 

 from May to September. The form- varies so greatly in its dif- 

 ferent stations that it suggests that some sparsely distributed spe- 

 cies of this genus should be referred to this.
