66 PITTONIA. 
my own fault in large part, wrong for V. Dicksonii. Figure 
5 of plateiii,as to all but the flower, was drawn from a 
small Canadian specimen fresh in all except the flower; and 
this part of the figure was supplied from a dried corolla ; 
altbough it does not at all represent the real coroila of either 
V. Dicksonii or V. cuspidata. But plate 6 was made from a 
dried specimen of true V. cuspidata which had been collected 
by myself last summer in northern Illinois. I must here do 
Mr. Holm the justice of stating that he, after having made 
the drawings for these plates, expressed the opinion that the 
specimen from Illinois and that from Canada were of differ- 
ent species; a conclusion which was forced upon myself as 
soon as I saw the two plants in flower side by side in my 
garden last May. 
V. ELEGANTULA. Acaulescent and low, the whole plant 
at time of petaliferous flowering barely 3 inches high and 
the peduncles far exceeding the leaves: rounded and cordate- 
reniform leaves pale-green and slightly succulent, about 4 
inch wide, short-petioled and the petioles erect, the margin 
lightly erenate and all parts wholly glabrous: peduncles 
obscurely angled, bibracteolateabove the middle, the bractlets 
subulate: sepals lance-linear, obtusish: corolla rather more 
thau j inch in length, not as broad as long; petals all similar 
in size and outline, oblong-obovate, obtuse or retuse, light- 
blue, the lower 3 with conspicuous violet veins on a white 
ground at base, the laterals bearing a low and thin tuft of 
short strongly clavate hairs, or some of them shortened to 
mere papille ; 2 upper petals naked, in full expansion de- 
flected and concealing the calyx: style elongated: late 
apetalous flowers small, aerial on short horizontal or recurved 
peduncles. 
Species collected by the Messrs. Macoun, not far from 
Ottawa, Canada, said to inhabit low moist places in the midst 
of sandy fields. It seems to unite the foliage of V. blanda 
with flowers of something like V. cucullata; though the
