Variety. 
2a C. a. 2 intermédius, C. intermédius Hort., has the 
habit of C. azireus, with pale flowers, like those 
of C. americanus, varying with different shades of 
blue. It was raised by Mr. Masters of Canter- 
bury, from seeds of C. aztreus fecundated by C. 
americanus, 
A very handsome shrub, profusely covered with brilliant 
celestial blue flowers in large panicles. In Mexico its bark 
is considered as a febrifuge. It is the most robust-growin: 
species of the genus, attaining, in 3 or 4 years from seat 
the height of 5 or 6 feet, or more, against a wall. It was 
at first treated as a green-house plant, but lately it has been 
found to be nearly as hardy as the North American species. 
In the winter ot 1837-8 these plants were greatly injured, 
but none of them killed. North of London the plant is 
less vigorous.

Spec. Char. §c. Leaves oval, 3-nerved, serrulated, smooth. Stem many- 
angled ; panicle thyrsoid in the axillary branches. (Don’s Mill.) A sub- 
evergreen shrub, or small tree. Monterey, Upper Californ‘a, and north- 
west coast of North America. Height in America 5 ft. to 20 ft. Intro- 
duced in ?1830. Flowers bright blue; May to November. Fruit black ; 
ripe about a month after flowering. 
In its native country, in favourable situations, this species becomes a small 
tree, with a stem sometimes as thick as a man’s arm, and strongly angular 
branches. In British gardens it forms a free-flowering highly ornamental 
shrub, with much of the habit of C. azireus; from which it chiefly differs 
in having the flowers in a close, instead of in an elongated, thyrse. Not- 
withstanding this difference, we consider it as only a variety of that species.

Spec. Char., §c. Branches somewhat pendulous. 
Leaves orbicular, elliptical or elliptical ovate, obtuse, 
subcordate, glandularly crenate, serrulate, coria- 
ceous, glabrous, and shining (as if varnished) above, 
velvety, canescent, and strongly 3-ribbed beneath. 
Panicles axillary, elongated, on rather long pe- 
duncles. (Yor. and Gray.) A shrub, probably 
sub-evergreen. North-west coast of North America, 
on subalpine hills. Height 2 ft. to 8ft. Not intro- 
duced. Flowers white. Fruit dry, 2—3-seeded. 
This is apparently a very desirable species ; and, as 
it is so abundant as to cover the whole declivities of 
hills, forming thickets very difficult to penetrate, we ~~ 
have no doubt that it will soon be introduced. 
Branches nearly glabrous. The leaves abound with an aromatic resin.
