4. Trifolium repens L. (Erith. Monograph on White Clover, pp. 

 1-x, 1-150. 1924. Duckworth & Co. London.) White Clover. Map 1218. 

 Found throughout the state. Common in lawns, waste places and pas- 

 tures and less frequent in fallow fields and open woodland and along 

 roadsides and railroads. Erith describes several varieties and forms and, 

 no doubt, some of them are in Indiana. 



Nat. of Eurasia; widely naturalized in N. A. 



5. Trifolium hybridum L. Alsike Clover. This species has been 

 freely sown as a pasture and fodder plant throughout the state and has 

 escaped frequently. No effort has been made to collect this species, 

 Trifolium pratense or Trifolium repens; consequently the maps do not 

 indicate the frequency with which they have escaped, but no doubt all 

 are found frequently in every county.

6. Trifolium reflexum L. var. glabrum Lojacono. Map 1219. The 



flowers of the plants I have seen are white and odorless and the pods 

 are about 4-seeded. I found it to be a common plant in hard, white, 

 slightly acid, clay soil in a clearing, formerly wooded with swamp white 

 oak and pin oak, along Little Pigeon Creek in Spencer County. I found 

 it in great colonies in a low, flat woods 10 miles southwest of Mt. Vernon 

 in Posey County where it was associated with post oak, agave, and 

 Baptism leucantha. Other specimens were found in dry woods, on a 

 cliff along White River, and in dry, sandy soil in a prairie habitat in 

 Vigo County. This is the western form of this species. The type came 

 from Augusta, Illinois. 



I have seen specimens from Va., Ohio (Wellington), 111., Iowa, Mo., and 

 Okla. 



7. Trifolium procumbens L. Low Hop Clover. Map 1220. Prob- 

 ably infrequent throughout the state along roadsides and railroads and 

 in pastures, open woodland, waste places, and fallow fields. 



Nat. of Eu. ; N. S. to Wash., southw. to Ga. and Miss.
