Cassia manlandica L. 



plant has been introduced throughout the state except in a few of our 

 western counties where there are prairie habitats. The preceding state- 

 ment is based upon the fact that complete stands of this species may be 

 found in suitable habitats along roadsides where the ground has been 

 made bare recently. The dense stands show the viability of the seed 

 and that the most important factor in reproduction is bare, sandy soil.

2a. Cassia fasciculata var. robusta (Pollard) Macbride. (Cassia 

 Chamaecrista var. robusta Pollard and Chamaecrista fasciculata (Michx.) 

 Greene, in part.) Stout Large-flower Sensitive-plant. Map 1197. One 

 of my specimens was found along a low roadside in Spencer County and an- 

 other in a fallow field along Otter Creek in Warrick County. Probably 

 native. Paul Weatherwax collected it in Greene County along the Illinois 

 Central Railroad near Bloomfield.

3. Cassia occidentalis L. Coffee Senna. Map 1198. Clapp, in his 

 Medicinal Plants of the U. S., published in 1852, on page 79, says: "Two 

 plants have been found growing on the banks of the river at this place, 

 apparently spontaneous." There is a specimen in the herbarium of 

 Wabash College, collected by Dr. Clapp, dated Sept. 14, 1850. There are 

 no other reports. The seed of this species are often used as a substitute 

 for coffee in tropical countries. 



Va., Ind. to Mo., southw. to Fla. and Tex.; also southw. through the 

 Americas to Bolivia and Paraguay and in the tropics of the Old World. 



4. Cassia hebecarpa Fern. (Rhodora 39: 413. 1937.) (Cassia 

 marilandica of authors.) Wild Senna. Map 1199. Found infrequently 

 throughout the state although there are no specimens from the south- 

 western counties. It prefers a moist soil and is found mostly along road- 

 sides and in pastures and open woods in the alluvial bottoms along 

 streams. In many places this species forms large colonies, especially in
