CANADIAN VIOLETS. 335 
U. S. homologue is the plant called by me V. obliqua on 
page 142 preceding; but it is also allied, and by its foliage 
more nearly, to V. cuspidata of the far-western lake and 
prairie regions, and distinct enough from either, by a re- 
dundancy of eharacters. If it has the hairiness of V. cus- 
pidata it has quite another quality of herbage, aerial apetalous 
flowers and fruits, and large pale obeordate petals instead 
of deeply colored and cuspidately acute ones. 
V. Macouxi. Rather larger than the preceding; early 
leaves subreniform-deltoid, 1 inch long, 14 inches broad, 
firm and rather fleshy, crenate, villous-hirsute beneath and 
on the upper part of the petiole, only sparsely hairy above, 
but the margin ciliate: pedicels bibracteolate in the middle ; 
sepals broad, obtuse, ciliate, somewhat callous-tipped ; petals 
lavender-color, very deciduous or almost caducous, all re- 
markably narrow and elongated, the two upper rather 
smaller than the others, the odd one the largest, all sparsely 
hairy over almost the whole inner face, the claws more or 
less distinctly ciliate: peduncles of the late apetalous flowers 
slender, short, horizontal, buried under decaying leaves or 
twigs; their pods distinctly trigonous, short and thick, as 
broad as long, dark with numerous purple blotches, the 
shortly and obtusely lanceolate sepals and their auricles 
ciliate. ; 
On dry limestone shingle, growing among grasses in the 
shade of cedars (Thuya) near Ottawa, J. M. Macoun ; n. 
18,746 of the Geol. Survey ; and near Hull, Quebec, John 
Macoun, n. 18.900. Very different from all other North 
American violets by its notably narrow hairy petals; nor 
have we any other of such habitat. 
V. vENUsTULA. Dwarf, with light-green glabrous herb- 
age: leaves cordate-ovate and deltoid-ovate, acutish, rather 
sharply and serrately crenate, cucullate when young, the 
blade less than an inch long, the slender petioles 1 to 3 
inehes long: earliest peduncles barely equalling the leaves,
