2. Psoralea stipulata T. & G. According- to Vail (Bull. Torrey Bot. 

 Club 21:113. 1894) the type specimen of this species was collected June 



8, 1839, by Wm. Jones on Rock Island at the Falls of the Ohio River, 

 Clark County, Ind. She also writes: "In the collections of C. W. Short, 

 preserved in the Herb. Acad. Phila., there are notes to the effect that he 

 never found this plant in fruit growing wild, and that he cultivated it 

 vainly for years. His collections of P. stipulata in the herbaria examined, 

 cover a period of some twenty years." J. M. Coulter wrote (Bot. Gaz. 1: 



9. 1876) that Dr. Clapp's collection contained a specimen. This specimen 

 was collected in 1838 in the vicinity of New Albany, Floyd County, and is 

 now in the herbarium of Wabash College. P. A. Rydberg wrote me that 

 the specimens in the New York Botanical Garden were immature and 

 might be some form of Desmodium. Thus it seems that this species, if a 

 valid one, is extinct. Known only from the type locality. 



3. Psoralea Onobrychis Nutt. Sainfoin Psoralea. Map 1223. Prob- 

 ably frequent to very rare throughout the state except in the extreme 

 northern counties. It is found mostly along roadsides and in alluvial 

 bottoms of streams. It is essentially a prairie plant but is occasionally 

 found in wooded areas and it is a question whether it exists in some places 

 as a relict or is an invader.

4. Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Free- 

 man. (Rhodora 39:426. 1937.) (Psoralea pedunculata Vail of Indiana 

 authors.) Map 1224. This species has a limited distribution in Indiana 

 but has a wide range of habitats. It is more or less frequent in the 

 unglaciated area on the crests and upper parts of the highest ridges, 

 usually associated with chestnut oak and black oak. In the southwestern 

 counties it is rare and is found in dry, sandy soil or in the lowland with 

 post oak. In the northwestern counties it is found in black and pin oak
