cut basal lobes; leaf lobes with parallel margins, not oblanceolate nor obovate as 

 in V. septemloba; flowers pale-violet; sepals with emarginate auricles; spurred

Wet open land or swampy woods and thickets, in s.e. corner of Tex., Mar.-Apr.;

6. Viola sororia Willd. Woolly blue violet.

 horizontal rhizome; leaves spreading, broadly ovate to reniform, entire, pubescent 

 on both surfaces with long hairs, sometimes villous; flowers varying in color from 

 light-lilac to reddish-purple or dark- violet-purple; sepals with short broad ciliate 

 auricles; peduncles of open flowers equaling or shorter than petioles; capsules large, 

 ovoid, purple or purple-spotted, prostrate or buried in leaves; seeds buff to brown, 

 ovoid, 1.75-2.5 mm. long. 



In sandy alluvial soils along streams, wet meadows, rich woods, thickets or dryish 

 woodlands, sometimes a weed in cities, Okla. ( Waterfall) and e. half of Tex., Mar.-

7. Viola nephrophylla Greene. 



Acaulescent perennial, spreading from horizontal somewhat fleshy rootstocks; 

 leaves erect or ascending, orbicular to slightly reniform, entire, glabrous except 

 for a scattering of tiny hairs on the upper surfaces of the lobes; petioles about 

 2 cm. long in summer; laminas of young leaves often purple on lower surface; 

 flowers light-blue; sepals with short blunt glabrous auricles; spurred petal villous; 

 capsules green, slightly ovoid, borne on erect peduncles above the leaves; seeds 

 with pronounced caruncles. 



Open wet fields, bogs, wet meadows, springy places, depressions in woods, willow 

 thickets and wet grasslands, rare in n.e. Tex., (?) Okla., N. M. (Rio Arriba, San
