but, like that of all the alders, it becomes reddish when it comes in contact 
with the air. The dwarf stature of this, and all the other American alders, 
renders them of no use as timber trees; but, according to Rafinesque, the 
leaves are vulnerary and astringent. The bark is styptic, and is used for 
dyeing brown, and, with vitriol, black. The inner bark of the root is emetic, 
and dyes yellow. The female catkins also dye black. Plants, in the Lon- 
don nurseries, are from 1s. to 1s. 6d. each; and seeds ls. per oz. At Boll- 
wyller, plants are 14 franc; at New York, 15 cents.

Spec. Char., §c. Leaves oblong, acute, rounded at the base; petioles and 
veins hairy on the under side ; axils of the veins naked; stipules ovate- 
oblong. (Willd. Sp. Pl., iv. p. 336.) A shrub, not above 3 ft. or 4 ft. high ; 
a native of Canada, and on high mountains in sphagnous swamps in Penn- 
sylvania. In the Berlin Botanic Garden, according to Willdenow, it was 
15ft. high in 1811. Plants, in the London nurseries, are 2s. 6d. each; and 
at New York, 20 cents; and seeds 1 dollar and 25 cents per pound.

Spec. Char., §c. Leaves heart-shaped, acuminate, dark green and shining. 
(Tenore.) A tree of similar magnitude to the common alder; a native of 
Calabria and Naples, in woods. Introduced in 1820, and flowering in March 
and April, before the developement of the leaves. 
** A large and very handsome round-headed tree, 
with broad, deep green, shining leaves, deeply 
heart-shaped at the base. It grows with rapidity, 
and is one of the most interesting ornamental 
trees that have of late years been introduced.” 
(Penny Cyc., art. Alnus.) It is a most distinct 
species; and, though a native of the kingdom of 
Naples, it is perfectly hardy. It ripens seeds in the climate of London, and 
might easily be rendered as common as A. glutindsa. There is a very 
handsome tree in the collection of Messrs. Loddiges ; and another in the 
Horticultural Society’s Garden. Plants, in the London nurseries, are 
Is. 6d. each ; at Bollwyller, 2 francs; and at New York, 50 cents.

a native of the high mountains of Hungary, Styria, and Carinthia; and of 
Germany, in the neighbourhood of Salzburg. Flowering, in Messrs, Lod- 
diges’s collection, in March and April; and ripening its seed in August. It 
was introduced in 1820. This plant is considered by many botanists as 
intermediate between the alders and the birches. It agrees with the alders, 
in having the peduncles of the female catkins ramose; and in general 
appearance it resembles the A’Inus incana in a young state: but it belongs 
to the birches, by the parts of its fructification, and by the number of its
