90 hee PITTONIA. 
The recognition of this species or subspecies as such, has 4 
been forced upon me by a most perfect series of specimens com- 
municated this year, by President Brainerd of Middlebury © 
College, Vermont ; these being accompanied by copious material 
of both F. blanda and V. renifolia from the same district, Earlier i 
specimens of V. Brainerdii in my herbariumare the Canad. Survey — 
Herb. n. 18,903, collected by Mr. J. M. Macoun at Beaver 
Meadows near Ottawa, 1898, no specific name given by Mr. — 
Macoun on the label, this fact indicating his inability, after ; 
studying it, to call the plant by any specific name. Again his : 
n. 21,685 from Cache Lake, Algonquin Park, Ontario, unidenti- ' 
fied by him, is V. Brainerdii with an unusual number of leaves 
imitative of those of V. Leconteana. His n. 21,648 from the 
same station, showing one Leconteana leaf, while the others 
are normal, he labelled V. amena., (i. e., Leconteana). Even 
Mr. Pollard’s n. 17 of our distribution of N. Am. Violace, ob- a 
tained in Ontario by Mr. Umbach, and distributed for V. reni- o 
Jolia is, at least as to the sheet I have, V. Brainerdii, though one of T 
the three specimens has not a little of the hairiness of V. reni- i 
folia on the upper leaf-face. The most northeasterly represen- 
tation of the species, with me, is from Prince Edward Island, 
and was communicated by my esteemed and valued correspond- : 
ent, Mr. L. W. Watson. 
V. VARIABILIS. Rootstocks short, stout, in at least the older : 
plants branching and the Scapes and leaves in so far tufted, : 
though only loosely; the habit rather slender, herbage of rather — 
soft-membranaceous texture and more or less pubescent through- — 
out, only the youngest leaves quite glabrous superficially but i 
their petioles hairy; peduncles commonly not quite equalling 
the leaves, the whole plant 4 to 7 inches high: leaves of great a 
variability on different plants (essentially alike on the same : 
plant), in some wholly uncut, merely crenate and of subreui- 
form-deltoid outline, 24 inches broad and 2 in length, cucullate 
in other plants all of subhastate-deltoid figure and deeply cleft . 
into oblong subfalcate segments; in others quite imitating those —
