216 LEAFLETS. 



To this I must append some account of what I shall call its 



Var. PAETHEiricA. 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 nje 

 and notes taken 3 May, 1906. 



Viola indttta. 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, 2} 

 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, coramonly 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.
