and will appear in the Flora Grceca, which is now preparing for the press by the president of the Linnean Society, under the name of aureus*, Both this and the paleflowered one from Mxsia, first described by Clusius in his Hist. Pann. p. 226, are growing at Mill Hill, and specimens are much at the service of the author alluded to above, if he wishes to publish them in the Botanical Magazine i his rapid talents, notwithstanding some mistakes from which nothing human can be totally exempt, have already stamped that work with a high degree of additional value.

The Melon Euphorbia is a native of the Cape of Good Hope, and seems to be dioecious; or, at least, that which flowered during the summer in one of the steves had none but male flowers, the pistils of which were abortive.
Stem withouf spines, fleshy, pyriformly globular, about three inches in thickness, with a hollow on the top, embossed with from eight to ten keel-shaped ribs, streaked by small traversing fillets of a pale green colour: the remnants of the dried-up peduncles that are often to be seen 4)xl the angles look like spines.

The flowers are produced on the sides at the top of the plant, supported on short, cylindric, pubescent peduncles with small scattered oval scales; some simple and oneflowered ; others terminated by an umbellet of 2, 3, 4, or 5 rays that are frequently bifurcated, with scales at their base. Central flowers commonly sessile.—Bractes two, small, applied to the calyx, which consists of ten segments ; the five inner of which are blunt, pubescent, and placed near the stamens; the others rounded, entire, patent, somewhat fleshy, greenish yellow, very minutely pitted.—Stamens 15—18. Filaments villous, intermixed with bearded threads, which are nothing more than abortive stamens. Anthers round, bilocular.—Pistil abortive.
With the female plant I am unacquainted, nor is any other than the male noticed in the Hortus Kewensis. That which we have in the Museum was sent last year from England,

Euphorbia aleppica. Aleppo Spurge.
Euphorbia umhella quinquefida, dichotoma; involucellis ovato-lanccolatis, niucronatis; foliis inferioribus setaccis (calyce octofido, laciniis quatuor cxterioribus bicornibus). Linn. Sp. PL 657. Lamarck Diet. 2. p. 433. This fine species of Euphorbia, originally from Syria and
the Islands of the Archipelago, flowered and bore fruit
during this summer for the first time.
from the rootstock spring several straight, simple, hcr3 baceous baceous stems, of about seven to nine inches in length, tapered downwards, and rendered scarred by the vestiges of fallen leaves.—Leaves glaucous,, smooth, sparse, very many ; lower capillary; upper linear-lanceolate, pointed.
Umbel composed of five or six bifurcated or dichotomous rays, below which are frequently produced peduncles that liear flowers. General involucre of 5—6 narrow, lanceolate leaflets; partial ones of two leaflets which are oval, pointed, and frequently edged with small teeth.—Calyx very small, of b divisions; £ outer yellow, furnished with two small lateral cuspides often reddish.—Styles emarginate.—Cap-' sules sleek.—Seed brown, rounded.
Clitoria heterophylla. Various-leaved Clitoria. Clitoria foliis pinnatis ; foliolis quinis; aliis rotundiori
bus, aliis lanceolatis, aliis linearibus. Lamarck Diet. 2v
The species of Clitoria that I am going to describe, is Tcmarkable for elegance of foliage ; for pretty flowers, which are rcsupinate, and of an azure blue colour; It flowered for the first time about the middle of summer in the hot-house. We are indebted to M. Cossigny for it, who brought the seed from the Isle of France, where it grows spontaneously.
Stem branched, climbing, filiform, above six feet in length, slightly puhesccnt.—Leaves alternate, lower ternate; middle and upper ones pinnate with an odd leaflet: leaflets.7—9, smooth, small, opposite, round, sometimes oval, lanceolate, or even linear, terminated by a bristleshaped appendage, and not unfrcquently emarginate.—' Stipules on. the stem, awl-shaped.
Flowers axillary, solitary, pendent, rcsupinate. Pedicles very slender, a quarter of an inch in length, slightly tumisl at the summit, furnished with four small bractes, two of which ;rre inferior; the two upper applied against the calyx.
