or shorter; petioles usually becoming longer 
than the blades; blades ovate, suborbicular or 
some of them hastate-reniform, obtuse or acutish 
at the apex, crenate, cordate or some of them 
nearly truncate at the base, mostly abruptly nar- 
rowed into the petiole, none lobed; sepals oblong- 
lanceolate, obtuse or acute; petals blue, more or 
less bearded; capsules 4’’-5’’ long, those of the 
cleistogamous flowers on spreading or declined 
peduncles; spur short, rounded. 
In dry soil, preferring shade, southern New York 
to Michigan, Nebraska, Virginia and Missouri.
