130 LEAFLETS. 
upper face little soin maturity: terminal leaflet cuneate-obovate, 
acute, the margin from the middle part upwards cut into about 
4 subserrate coarse teeth on each side; laterals smaller, ovate 
or ovate-oblong 3-toothed on one side, 1-toothed on the other: 
spikes 3 at each axil of one or two upper leaves, each 3 raised 
on a distinct pedunculiform twig ; bracts glabrous except mar- 
ginally: fruits small, scarcely compressed, hirsute. 
Of northern New York and adjacent Canada, so far as known; 
my type for foliage, inflorescence and growing twigs being from 
Jones’ Falls, Ontario, 26 May, 1891, by J. Fowler, as in U. 5. 
Herb. A sheet in my own herbarium, collected at Henderson, 
N. Y., Aug. 1896, by Mr. Tidestrom, is in good fruit. 
S. cRATAEGIFOLIA. Evidently low, with rigid short spread- 
ing branches always glabrous, even when growing: foliage sub- 
coriaceous, deep green and minutely pubescent above, paler and 
softly villous beneath; terminal leaflet broadly obovate, obtuse, 
14 inches long, 1} broad above the middle, below the middle 
entire but broad and not cuneate, only acute at base, the upper 
one-half coarsely crenate-dentate ; the lateral leaflets half as 
large, obtuse at base and crenate or dentate all around the 
margin: fruit small and in small scattered clusters, sparsely 
hirsute. 
North Pownal, Vermont, 25 July, 1898, W. Eggleston, n. 172 
as in U.S. Herb. Of firmer foliage than any other northern 
species, the leaflets strikingly like the leaves of several North 
American species of Crataegus. 
S. ARENARIA. Low shrub with erect rather simple branches 
delicately puberulent the first season, later dark red-brown, 
glabrous: leaves small, thin, minutely strigulose-pubescent on 
both faces ; terminal leaflet 1 to + inches long, narrowly obovate, 
not notably cuneate, the summit with one terminal, and on each 
side two lateral rounded lobes, the lateral leaflets similar but 
smaller: spikes 8 to 10, one at each node of all the upper part 
of the stem, which thus becomes a kind of elongated compound 
Spike; bracts glabrous on the back, ciliate: fruits small, 
densely hirsute.
