pairs of leaves, the lower ones narrowed at the base and usually more or less 



petiolate 3. P. ovata. 



Leaves of vegetative shoots sessile or the lower on short petioles; blades lanceolate 

 to ovate-lanceolate, elliptic or obovate, narrowed at the base but not long 

 taper-pointed, subacute or rounded at the apex. 

 Apex of leaves of vegetative shoots acute or subacute; corolla tube glabrous, 



petals usually notched; plant found throughout Indiana 8. P. divaricata. 



Apex of leaves of vegetative shoots rounded; corolla tube pubescent, petals 

 never notched; plant found to the southeast of Indiana. (See excluded 



species no. 512, p. 1082) P. stolonifera. 



Leaves linear, acute or subulate, more or less fascicled; low, diffuse plants, creeping 

 or decumbent, generally less than 2 dm high. 

 Nodes few; lower leaves 20-60 mm long, sharply acute; sinuses of corolla lobes aver- 

 aging 3 mm deep 9. P. bifida. 



Nodes numerous, crowded; lower leaves 8-20 mm long; sinuses of corolla lobes

1. Phlox paniculata L. Garden Phlox. Map 1681. Infrequent through- 

 out the state except in the northern counties ; in wooded flood plains of 

 streams and rarely in wet woods away from streams or elsewhere. I have 

 a narrowleaf form from a wooded cliff. The northern tier of counties 

 in Indiana has been botanized more thoroughly than any other area of the 

 state, yet the species has been found in only a few of these counties because 

 it reaches its northern limit in northern Indiana. 



Pa. to 111. and Kans., southw. to Fla. and La. 



2. Phlox amplifolia Britt. Map 1682. We have had this species under 

 cultivation for eleven years and it is very thrifty, has a long blooming 

 period, and is one of the best phloxes for cultivation. 



Found locally on open, wooded slopes and on wooded flood plains of 

 streams in a few of the Ohio River Counties. 

 Ind. to Mo., southw. to Tenn. 



3. Phlox ovata L. (Wherry. Bartonia 13: 25-29. 1932.) MOUNTAIN 

 Phlox. Map 1 1683. A few colonies on slopes in white and black oak
