This little delicate aquatic, growing naturally in pools and lakes of
fresh water in India and Cochinchina, and quivering at every breeze,
its roots having no attachment to the soil, and the foliage yielding
but little to that of the Mimosa pudica in sensibility, forms a most
striking contrast to the Anneslea spinosa of our 128th number. Father
Loureiro, who calls it Neptunia oleracea, informs us that in China
and Cochinchina, where they cultivate it as a salad herb in pools and
slow-flowing streams, they are accustomed to tie the plants to stakes,
to prevent their floating to a distance.
A description of the plant, accompanied by an elegant figure, will
be found in the 2d volume of Dr. Roxburgh’s Plants of the Coast of
Coromandel, under the name of Mimosa natans; but from the total
dissimilarity between the fruit and that of the genus Mimosa, we
have preferred following the arrangement of Professor Willdenow. The
specimens from which the drawing was taken were obligingly communicated
by Mr. Milne last September from Fonthill. The plant is annual, and
according to Mr. Donn’s Catalogue (where see Mimosa natans) was
introduced to this country in 1802.

informed by the collector, that the species is considerably dwarfer in
Pinang than the A. elegans, and also much more bushy and compact.

The Storax tree is a native of the Levant, of Italy, and of the
southern parts of Provence in France. The tree is very ornamental, but
requires the shelter of a wall in this climate, and while young either
to be kept in the green-house or covered during severe frosts. The time
of flowering is June and July, but ripe fruits are rarely produced in
this country. The principal importation of Storax is said to be from
Turkey, where it is obtained both by gathering that which naturally
exudes from the trees, and also by making artificial incisions, to
which hollow reeds are affixed to receive it. From the accounts of
some travellers published by Du Hamel, we learn that they generally
adulterate it by mixing it with wax. The Storax-tree is by no means a
new acquisition in this country. Gerard in his Herball, published in
1597, informs us that he had two small trees of it in his garden. It
is however still a very scarce plant, and only to be found in a few of
the principal collections, which, we are informed, is occasioned by the
great difficulty of propagating it either by cuttings or layers.
The specimen was communicated, in the beginning of last June, from the
well known garden of the Company of Apothecaries at Chelsea.

forests in the eastern parts of Hungary, during their botanical
excursions in that before nearly uninvestigated region, and published
in their Figures and Descriptions of the rare Plants of Hungary, above
quoted, at Vienna in 1802. The plant was introduced to this country by
Mr. Donn of Cambridge in 1808, and from fine flowering specimens which
he communicated last May the present drawing was taken. The common
height of the plant is said to be from three to five feet, and the
thickness of the stem about an inch. It is perfectly hardy, and has not
as yet been enumerated in any catalogue of plants cultivated in this
country.

We received the specimen from which our figure is taken from A. B.
Lambert, esq., in whose stove it has flowered for the first time in
this country. It was brought to England last year by Mr. Fraser from
South Carolina. Many attempts have been before made to introduce it,
but without success, as the plants either perished on the voyage, or
very soon after their arrival. It is, we think, a great acquisition to
our collections, on account of the great fragrance of its leaves when
dried, which very much resembles the fine perfume of the Tonquin Bean,
(_Dipterix odorata_ Linn. Willd.) but more powerful, and which they
will retain for many years, as Mr. Lambert has shown us some which have
been kept in a box above ten years, and are as highly scented as ever.
It seems at present too tender to flower without the assistance of the
stove.

This is one of the species referred to in our description No. 605, and
flowered last November in the collection of T. Evans, Esq. at Stepney;
where we were informed, that it grows naturally in shady woods in
Pinang, or Prince of Wales’s Island, and was introduced to this country
in 1808. Its beauty is certainly far inferior to the Bengal species,
with which however it agrees very well in essential characters; but
the nectary here nearly resembles a little cup, and is not contracted
above, as in that species. The height of the plant above ground is only
about two inches.

bearing many flowers.

This remarkable species of Ipomœa was brought from Mrs. Benyon’s
hothouse at Englefield, Berkshire, last August, where the plant, after
rising to the top of the trellis, extends both right and left to a
length of about 30 feet, branching in various directions with hundreds
of bunches of flowers. The foliage is singular as to texture, varieties
of form, and colour; the lower leaves being of a strong purple on their
under side, and dark green above. The plant is perennial, and continues
flowering during the greatest part of the summer, but does not ripen
its seed--most probably owing to the extreme luxuriance of its
inflorescence. All our attempts to discover its native soil, or time of
introduction, have proved abortive; neither have we been able to find
that any account of it has before been published, or any specimens of
it in herbariums.
The propagation is by cuttings; and we are informed that Mr. Lambert,
who favoured us with the specimens, is already in possession of some
very fine plants of it.

The genus Trichilia is certainly at present in a confused state, from

appears to contain at least two genera. This fine species is said to
have been sent over to England from the botanic garden in the Island of
St. Vincent’s by Doctor A. Anderson about the year 1801, and is not we
believe (at present) in any other collection but that of Sir Abraham
Hume, who favoured us with the specimen here delineated in fine bloom
last summer (1810). It possesses the same fragrance that is attributed
to the Trichilia moschata, of which we have never seen specimens.

Mr. J. Fraser informs us, that his father and himself discovered this
singular species of Carex, in the autumn of 1808, near the Table
Mountain, and upon the banks of the Catawba River in the neighbourhood
of Morgan Town, North Carolina.

This fine plant is perfectly new to the British gardens, and the only
species of a genus named and figured by Labillardiere in his _Nova
Hollandia_, or Description of New South Wales.
It was raised from seed in the summer of 1807, in the collection of the
Right Hon. Lord Grenville, at Dropmore, who favoured us with specimens
in full bloom, last June, 1811, being the first time of its flowering
in this country. His Lordship’s botanic gardener informs us that the
plant is about eight feet high, and the stem one inch and a quarter in
diameter; that during the first year it had the appearance of being
herbaceous, but afterwards became woody; its growth is very luxuriant,
flowering at the termination of every branch, and seems as if it would
thrive in any sort of earth, and was nearly if not quite hardy, as the
roots remained in the ground one year at Dropmore, and shot up strong
again in the summer. It may be increased by cuttings, and will be found
not only an acquisition in point of novelty, but ornamental from its
numerous light graceful blossoms, which possess an agreeable fragrance.

It was first raised in the Royal gardens at Kew, about the year 1809,
and is as yet in very few collections. Our figure represents an entire
plant from the conservatory of the Countess de Vandes, which flowered
in the month of June 1811, and perfected its seed about the middle of
September, at which period its slender branches had grown nearly six
inches longer (than they were when in bloom), and, twining round a
small stick placed for their support, had every appearance of becoming
a graceful climbing plant.
