- 296 PITTONIA. 
I have no doubt that what I here define and name as 
new, has been treated as the equivalent of the V. palus- 
tris of the Old World; but the plant so named in our books 
has not been reported from so far south as New York; nor 
is our V. crenulata at all suggested by Britton and Brown's: 
figures of so-called V. palustris. 
V. FrLETCHERI. Acaulescent, small, the simple ascending 
rootstock rather small for the plant, closely jointed: leaves 
few, small, from ovate-reniform to subcordate ovate, $ to 1 
inch long at time of petaliferous flowering, the undevoloped 
ones cucullate, all very regularly crenate, glabrous and 
shining above, mostly sparse-hirsutulous beneath and on 
the petioles, these in the earliest not longer than the blade, 
in the later more than twice as long: flowers very few, often 
1 only; peduncles hirsute, minutely bracted below the 
middle: sepals small, lanceolate, veinless, serrate-ciliolate: 
corolla large, more than $ inch broad, rich purple; the 
upper pair of petals much the largest, obovate, the middle 
pair narrower in proportion and strongly bearded with long 
cylindric hairs, the odd one as long as these and a trifle 
broader: apetalous flowering and fruiting not known. 
Common in certain moist open grounds, growing among 
mosses, near Ottawa, Ontario, Mr. J. M. Macoun. Plant of 
about the size of V. venustula, but with very different 
characters, and holding perhaps the same relation to the 
common V. papilionacea which V. venustula bears to V. 
cucullata. The individuals are said by Mr. Macoun to 
grow singly, and to be often one-flowered. The leaves at 
time of petaliferous flowering are only three or four. Some 
small plants of V. blanda accidentally accompany the living 
specimens, showing that these two are natural associates. 
V. NoDOSA. Acaulescent, the rather ample foliage and
