NEW SPECIES OF CERASTIUM. 297 
long peduncles from stout horizontal more or less branch- 
ing and strongly knotted rootstocks: herbage light green, 
hirsutulous, the petioles and peduncles very strongly so 
and the ‘hairs spreading or deflexed: leaves from round- 
-reniform to round-ovate, obtuse, subserrate-crenate, about 2 
inches wide at time of petaliferous flowering, the unde- 
veloped ones cucullate, all much shorter than their petioles: 
peduncles equalling or exceeding the leaves, rather slender, 
bibracteolate near the middle, the pubescence rigid and re- 
trorse: sepals lanceolate, puberulent, the margin more or 
less obscurely ciliolate: corolla pale-violet, $ inch broad; 
uppermost petals obovate, naked, the laterals with a dense 
tuft of apparently flattened and distinctly woolly hairs, the 
odd one as long as the others and broadly spatulate. 
Near Syracuse, New York, communicated by Mr. Homer 
D. House. Related to such species as V. cuspidata, V. 
Dicksonii and V. letecerulea, and remarkable for its large 
knotted and exactly horizontal rootstocks, the woolly- 
hairiness of its petals, and the retrorsely almost hispid 
peduncles.

with about 4 pairs of suberect leaves and ending in a sessile 
 eontracted cyme, the whole stem purple or purplish and 
glandular-pubescent with white spreading hairs: leaves 
lance-linear, acute, of half the length of the internodes or 
somewhat more, rather sparsely glandular-hirsutulous and 
almost equally so on both faces; basal sterile branches very 
short, consisting of little more than fascicles of obovate- 
oblong carinate-nerved at length almost glabrous leaves of
