Descr. Shrub from two to three feet or more in height, the thickest part

of the stem not exceeding the size of the little finger, covered with a

smooth brown bark, irregularly branched; Flowers appearing before the

leaves are fully expanded, and produced in umbels at the extremities of

the branches, from eight to twelve or more in an umbel, of a fine yellow

colour and agreeable fragrance; each blossom is about the size of that

of the horse-chestnut, and as some of them are produced much earlier

than others, the plant of course continues a considerable time in bloom,

standing on short peduncles; Calyx very short, viscous, and irregularly

divided, most commonly into five ovato-lanceolate segments; Corolla,

tube cylindrical, viscous, grooved, brim divided into five segments,

undulated and somewhat wrinkled, ovate, pointed, three turning upwards,

two downwards, of the three uppermost segments the middle one more

intensely yellow than the others and inclining to orange, with which it

is sometimes spotted; Stamina usually five, yellow, projecting beyond

the corolla, and turning upwards near their extremities; Antheræ

orange-coloured; Pollen whitish and thready; Germen somewhat conical,

evidently hairy, and somewhat angular; Style yellowish, filiform,

projecting beyond the stamina, and turning upwards; Stigma forming a

round green head.

The figure and description here given were taken from a plant which

flowered by means of artificial heat, in the spring of 1798, at Mr.

Watson's, Nurseryman, Islington, and which had been introduced the same

year, by Mr. Anthony Hove, of Warsaw.

As an hardy ornamental shrub, it bids fair to prove an acquisition truly

valuable, its flowers produced in the months of June and July, being

highly ornamental as well as fragrant.

We have the best authority for regarding this plant as the

_Chamærhodendros Pontica_ of Tournefort, it agrees with his own

specimens in Sir Joseph Banks's Herbarium, it accords also with his

description, and figures, more especially of those flowers which are of

their natural size; nor have we any doubts of its being the _Azalea

Pontica_ of Prof. Pallas, figured in the _Flor. Rossica_, since it

corresponds generally with his description, though not in all points

with his figure, which bears evident marks of inaccuracy, the stigma,

for instance, is represented as trifid.

Tournefort found this plant on the eastern side of the Black Sea, Mr.

Hove on the north side near Oczakow, and elsewhere; Professor Pallas on

Mount Caucasus.

As yet there has been no opportunity of ascertaining the best means of

propagating this new denizen, but there is every reason to suppose that

it will succeed with the treatment bestowed on the other _Azalea's_.

Prof. Pallas relates that the honey of bees frequenting the flowers of

this plant is supposed to be narcotic, and that goats, kine, and sheep

on eating its leaves have been poisoned thereby.

By permission and with the approbation of Mr. Anthony Hove, the

following extracts from his journal are here inserted.

"June 9, 1796, found a few of this species of _Azalea_ on the river

Dnieper in swampy ground, four feet high, beginning to blow, called here

the stupifying shrub, and considered by some as highly efficacious in

curing the venereal disease.

"June 20, found this species on the river Dniester, on the estate of

Count Stanislaus Sczesny Potocki, about sixteen English miles from the

town of Mohilow, in peat earth, from four to twenty feet high; regarded

by the common people as intoxicating, and used in the cure of various

diseases.

"July 4, near Oczakow, found thousands of these plants fully blown, in a

marsh, every spring-tide overflown by the sea; found there also, a

Tartarian farmer, who lived entirely by the profits arising from the

honey which the bees extracted from the flowers of this plant, sold to

Constantinople and other parts of Turkey for medicinal uses.

"July 15, arrived at Trebizond, found a valley about ten English miles

from the sea covered with these plants."

On cultivation, Mr. Hove relates that he found the _Azalea's_ from

Trebizond much more tender than those from the borders of the Dnieper

and the Dniester, and was therefore inclined to regard them as strong

varieties if not distinct species.

The leaves, when fully expanded, are in size and figure like those on

the plate, hairy on both sides, and terminating in a very remarkable

blunt mucro or point, which has not been noticed either by those who

have described or figured the plant as it deserves, for it appears to

form a very strong character.
