XXXVI. 1. THE DOTTED-FRUITED THORN. 435 
Sp. 3. ‘Te Pear-teavep Tuorn. C. tomentosa. LL. 
A much branched shrub usually eight or ten feet high, but, 
when surrounded by other plants, eighteen or twenty, with 
bark, on the branches and small tranks, of a bright reddish, pol- 
ished green, or a shining brown, on the recent shoots dotted 
with elliptic, raised, brown dots. The thorns are axillary, from 
one to three inches long, and pointed. The flowers are ldrge 
and fragrant, on broad, leafy corymbs. The segments of the 
calyx are long and slender and glandular-serrate, and, with 
the flower-stem, downy. The styles are usually 3. The fruit 
is large, orange red, pear-shaped. 
The leaves are of a firm, leathery texture, rather deeply fur- 
rowed on the upper surface, large, sometimes five inches in 
Jength and three in breadth; ovoid, tapering rapidly at base 
into a footstalk which is margined to the bottom; doubly ser- 
rate, sharply cut towards the extremity, which commonly ends 
in an acute point; downy on both surfaces when young, smooth 
finally on the upper surface, but with the veins beneath perma- 
nently covered with a short down. 
This is one of our most common and hardy thorns. It is 
well fitted to form a part of a hedge, but is objectionable on ac- 
count of the early fall of the leaf. It should, therefore, be min- 
gled with sweet-briar and the buck-thorn. 
It flowers in May and June, and ripens its large fruit in Oc- 
tober. Found from Canada to Kentucky. 
Sp. 4. Tse Dorren-rrvirep Torn. C. punctdta. Jacquin. 
A handsome shrub, eight to twelve feet high, rarely more, but 
sometimes twenty or even twenty-five. The trunk, sometimes 
straight, is usually contorted and zig-zag, covered with a rough, 
much fissured bark, 
The recent shoots have the dark brown, polished bark, cha- 
racteristic of the thorn; the older branches are of a greenish 
gray, smooth or channelled with many small grooves. Thorns 
commonly long and stout, scythe-shaped. Leaves inversely 
egg-shaped, rounded towards the extremity, and wedge-shaped 
at base, tapering downwards and running along in a wing upon
