290 PITTONIA. 
slender peduncles little more than an inch long, bibracteo- 
late much above the middle: sepals subulate-lanceolate, 
glabrous: corolla small, deep-blue; spur elongated, oblique. 
In rocky woodland near Aylmer, Quebec, Canada, 6 June, 
1901, Dr. J. Fletcher. Allied to the common V. Muhlen- 
bergiana of the U. S. (now righly or wrongly called V. 
Labradorica), but easily distinct by its small, thick and 
somewhat fleshy foliage always of ovate outline and obtuse; 
the flowers not half as large, much more deeply colored, 
and with a different spur. 
V. RETROSCABRA. Root long and deep, with short 
branched crown or caudex, the proper stem at time of petal- 
iferous flowering not developed, the large long-petioled 
foliage quite surpassing all the flowers, in outline from sub- 
cordate-deltoid to codate-ovate, 1 to 2 inches long and ? to 
14 inches broad, the sinus broad and open, the margin 
unevenly erenate, petioles of the largest 3 inches long or 
more, the whole herbage more or less hirtellous and this 
hairiness retrorse when occurring on the petioles and pe- 
duncles; the latter bibracteolate, at about the middle: sepals 
subulate-lanceolate, acute, often puberulent: corolla about 
10 lines long, pale-violet or bluish, petals rather narrow, the 
keel as long as the others and rather broader: stems devel- 
oping in summer to the length of 2 or 3 inches, and bearing 
numerous small apetalous flowers, these succeeded by short 
ovoid capsules. 
A plant of southern Colorado, first known to me in some 
autumnal specimens collected by myself in exssicated bog 
land near Cimarron, 1896. Similar specimens were distrib- 
uted from near Mancos, by Baker, Earle and Tracy, in 1898, 
under number 116. Others, also late and only in fruit, 
were distributed by Mr. Baker, from Pagosa Springs in 1899. 
Lastly, excellent flowering specimens are now at hand from
