Crotalana sagittalis L 



where its habitat occurs. About 4 miles east of Madison, Jefferson 

 County, it forms a dense stand for about a quarter of a mile along the 

 bank of the Ohio River where its common associate is Desmanthus illinoen- 

 sis. In 1935 Edwin D. Hull found a colony along the New York Central 

 Railroad tracks in Lake County. It was doubtless a railroad migrant.

3. Baptisia tinctoria (L.) R. B. var. crebra Fern. (Rhodora 39: 414- 

 415. 1937.) Yellow Wild-indigo. Map 1208. Very local in the north- 

 western counties. Outside the range indicated on the map it has been 

 reported from Kosciusko and Tippecanoe Counties. I have found it on a 

 high, gravelly, wooded bank, in open places in woods, in prairie habitats, 

 and most often in depressions in low, sandy black and pin oak woods 

 where tree growth is sparse or absent. Judging from the vegetation in 

 such depressions the soil is slightly acid. 



In 1923 I found an aberrant form, probably a hybrid of this species, 

 in Starke County with 40 flowers on the terminal raceme. 



This genus is now being monographed and this plant will be given con- 

 sideration.

4. Baptisia leucantha T. & G. White Wild-indigo. Map 1209. Infre- 

 quent in its habitat throughout the state and usually only a few plants 

 found at a place. It is most commonly found in sandy soil in prairie 

 habitats and in thin oak woods. It is also found in hard, clay soil or 

 gravelly soil on white oak slopes, in hard, white clay of the "flats" of 

 the southern counties, and once I found it on a bar in the Wabash River.

1. Crotalaria sagittalis L. Rattle-box. Map 1210. I have collected 

 this species four times and all of the plants were found in old, fallow
