216 LEAFLETS. 
To this I must append some account of what I shall call its 
Var. PARTHENICA. Earliest foliage larger, thinner, not pur- 
plish beneath, transversely elongated, but hardly subreniform, 
being subtruncate across the base; sepals narrower, as also the 
petals in the same degree, and these rather bluish than violet, 
and in most specimens definitely but narrowly whitish-margined, 
the odd petal very decidedly shorter than the others. 
More open wooded slopes and summits on the Virginian side 
of the Potomac not far from the Chain Bridge; collected by me 
and notes taken 3 May, 1906. 
VIOLA INDUTA. Of the low stature of the preceding at first, 
and with like small subreniform early leaves, the petioles of these 
but not the blades hirtellous, the peduncles of petaliferous 
flowers almost filiform and quite glabrous: sepals lance-oblong, 
obtuse, closely ciliate with short, stiff spreading hairs: corolla 
small for this group, usually blue, rarely purplish or violet, the 
petals subequal, all but the odd one very distinctly and rather 
deeply emarginate. Plant in summer state not large in propor- 
tion, 8 or 10 inches high, copiously leafy and the leaves light- 
green, of firmer texture, their petioles hirsute, even hoarily so 
when seen standing and fresh, blades broadly subcordate and 
emphatically cucullate, when pressed out appearing somewhat 
roundedly deltoid-subcordate, the length and breadth equal, 24 
inches: peduncles of apetalous flowers, short and very stout when 
buried, or when above ground still short and stoutish, ascending 
or horizontal. 
In rather open ground bordering woodlands, commonly on 
open banks, always in soil of red clay mixed with sand; this at 
various stations among the hills outside the District line in 
Maryland; near the bridge over Powder Mill Branch quite 
copious; petaliferous flowers in the latter part of April, my 
specimens 21 April, 1906; of summer stage May and June of 
former years and also this season; apparently first obtained by 
me near Cabin John, in clayey-sandy bottom land ten years ago, 
that is, in 1896, 31 May, all the specimens being in the summer 
stage.
