The flowers are of a clear bright yellow colour, about 11 in. wide when expanded, with a column of white stamens in their centre.' "Every one knows that the spines of the Cácteæ are always difficult to extract when they have entered the skin. If the spines are magnified, it will be found that this property is owing to their being closely covered, from the point downwards, with numerous barbs, which have their cutting bases directed towards the base of the spine: in appearance they are very like the arrow-heads with several rows of barbs, such as are used by certain Indian nations. "An interesting fact relating to the common European opuntia is mentioned by M. De Candolle : Among the practical consequences,' he observes, that results from the facility with which the Cáctea strike from cuttings, there is one which, on account of its importance, deserves to be noticed: it is the manner in which the opuntia is employed to fertilise the old lavas at the foot of Etna. As soon as a fissure is perceived, a branch or joint of an opuntia is stuck in; the latter pushes out roots, which are nourished by the rain that collects round them, or by whatever dust or remains of organic matter may have collected into a little soil. These roots, once developed, insinuate themselves into the most minute crevices, expand, and finally break up the lava into mere fragments. Opuntias treated in this manner produce a great deal of fruit, which is sold as a refreshing fruit throughout all the towns of Sicily.'" (Bot. Reg., Aug.) LVI. Myrtacea. 1493.

"With us," says Dr. Graham, it is rather a slender shrub. We have not yet ascertained whether, like the pulverulénta, it will thrive without the protection of a wall." This shrub, though not showy in its flowers, is graceful in its pendulous branches, and long, narrow, lanceolate green leaves. (Bot. Mag., August.) LXXIII. Rosacea. 1523.

It is strikingly different from all the known species of simple-leaved brambles in its finely cut stipules and bracteas, which are covered with numerous little transparent green glands; giving all the parts that surround the petals an appearance of being sprinkled with green dew. R. róridus is chiefly an object of botanical interest, there being little in it to attract the mere lover of showy flowers. Its fruit is unknown. (Bot. Reg., August.) LXXVII.

(Bot. Mag., Sept.) Astragalus vesicàrius (bladdery-calyxed milk vetch) is figured in the Botanical Magazine for September, t. 3268., where the following remarks on it are given: "This very handsome and very highly desirable species is a native of barren wastes in the south of France, and of Russia as well as of Hungary, and is perfectly hardy: it flowers in May. Although, as cultivated in the Glasgow Botanic Garden from seeds communicated by M. Otto of Berlin, the flowers are always of a rich purple colour, becoming darker and almost blue in age, yet they appear, in a wild state, to be sometimes cream-coloured or white."

A slender twiggy shrub, remarkable for a glutinous substance which clothes not only the young stems, but (although in a less degree) the young foliage also. Mr. Cunningham discovered this species" in the country around Bathurst [New Holland], where it flowered throughout the winter. It also adorns the barren hills near Cox's River, at the cool season of the year; and in about December its pods are ripened. With us, at Kew, it blossoms in the spring, along with many others of its kindred; mingled with which, it forms an agreeable contrast by its slender habit and deep yellow flowers," which are grouped into globular heads, seated on short axillary stalks.

We have kept it very well in the green-house, potted in light loam and peat. It increases itself freely by offsets. (Bot. Cab., Sept.) Oxalis crenata (Vol. VIII. p. 16., Vol. IX. p. 78. 232.] appears to be one of the most accommodating and prolific plants I know; but it cannot have too rich a soil. The only plant which has flowered in this neighbourhood is one raised by a gardener of the name of Saunders, from a tuber weighing only 28 grains, which he planted in an old cucumber bed, and which has produced a bush as large as a gooseberry bush. This plant flowered on the 5th of August, and has produced above 1000 blossoms, making a most splendid appearance; but these all fall off without producing seed. The brief descriptions of this plant, given in De Candolle's Prodromus and Turton's translation of Linnæus's Systema Nature, are extremely vague and inaccurate. De Candolle speaks of the umbel as 5 to 6 flowered, while it really is from 10 to 13 or 14 flowered. The calyx is deeply 6 or 7 cleft; the corolla is 6, 7, or 8 petaled; and the number of stamina is 15 or 16, arranged in two rows, in the outer of which the filaments are above one half shorter than the 9 or 10 within. —Wm. Hamilton. 15. Oxford Place, Plymouth, Aug. 26. 1833. In a previous letter, dated March 9. 1833, Dr. Hamilton remarked, that a knowledge of the proportion of amylaceous contents in an equal weight of the tubers of Oxalis crenata Jacq. and of those of the potato (Solanum tuberosum L.) is very desirable; and that it is to be hoped cultivators of, and experimenters on, the Oxalis crenàta will direct their efforts to the determination of this point.

It is nearly allied to P. alàta and quadrangulàris; from which it differs in having only two glands at the upper end of the leafstalk, and in the form of the leaves of its involucrum. Its flowers are also much more brilliantly coloured than are those of either P. alàta or P. quadrangulàris. The petals, on their inner surface, are of a rich deep scarlet; on the outside, deep violet, with a white streak along the middle. The crown is about as long as the petals, composed of several rows of tapering processes; which are collected into a cylinder, and are white, with crimson bands on the lower half, and, on their upper half, a deep rich violet."

Dracophyllum secúndum is figured in the Botanical Magazine for September, t. 3264.; where Mr. Allan Cunningham remarks, of this elegant and interesting shrub, which was first raised in this country from seeds that he gathered near Port Jackson, and transmitted in 1823, -" It is found in shaded ravines, and such humid situations as the ferns delight in. In its native country, its habit is different from that which it not unfrequently assumes when under cultivation; for, growing there, as it always does, on wet sandstone rocks, almost wholly denuded of soil, its raceme is much fewer flowered, and the plant itself altogether of slenderer growth..... The plant is a very desirable one for cultivation, as it flowers freely with the protection of a green-house; and there ripens seeds, by means of which it may readily be increased." (Bot.

It agrees with that species in having a tuberous rootstock, a twining succulent stem, in the leaves, and in the form of the corolla; but it is at once distinguished by the corona, or crown of the stamens, which equally separates it from every other species with which I am acquainted. I would take this opportunity of calling the attention of botanists to the form of that organ, as affording the most permanent characters for distinguishing allied species in this genus.” (Dr. Wight, in Bot.
