 Polygala verticillata 

 var. sphenostachya Pennell 



not able to separate satisfactorily the wideleaf from the narrowleaf form. 

 Large, branched plants may have on one branch leaves of the typical form 

 and on others leaves like those of the variety. The width of the spike is 

 another character used to separate the two forms and it happens that in 

 my 34 specimens the widest spike is on a plant with narrow leaves. The 

 stems of small plants are always simple but large plants may be either 

 simple or branched. Plants of a prairie or sandy habitat have narrower 

 leaves than those of wooded limestone slopes. 



Usually on wooded slopes along streams and about lakes. Rarely in the 

 open in a prairie habitat. 



Southern N. B. to the eastern shore of Hudson Bay, westw. to Alberta, 

 southw. to Ga., Tenn., and Ark. 



4. Polygala verticillata L. (Polygala Pretzii Pennell.) (See Fernald's 

 discussion of this species in Rhodora 40: 337-338. 1938.) Map 1313. 

 Mostly near streams and lakes in dry sandy soil in black and white oak 

 woods ; rarely in the low sedge border of lakes.

5. Polygala verticillata var. isocycla Fern. (See Fernald's discussion 

 of this species in Rhodora 40: 334-336. 1938.) Map 1311. In poor soil in 

 black and white oak woods and rarely in moist prairies. Rare. 



Mass., Ont., and Man., southw. to Fla. and Tex. 



5a. Polygala verticillata var. sphenostachya Pennell. Map 1312. My 

 only specimen is from a sandy roadside cut four and a half miles north 

 and a mile and a half west of Morocco, Newton County. Other specimens 

 have been collected in Putnam, St. Joseph, and Tipton Counties. 



Ind. to Nebr. and Kans. 



6. Polygala ambigua Nutt. Map 1314. In poor soil on open wooded
