It appears to the greatest advantage, when trained up an upright pole, nearly to the height of the back of the stove, and then suffered to run along horizontally.
By some it has been considered as a variety only of the _Passiflora quadrangularis_, others, with whom we agree in opinion, have no doubt of its being a very distinct species; it differs from the _quadrangularis_, in having leaves more perfectly heart-shaped, and less veiny; in having four glands on the foot-stalks of the leaves, instead of six; and in not producing fruit with us, which the _quadrangularis_ has been known frequently to do.
The Nursery-men report, that this species was first raised in this country, by a gentleman in Hertfordshire, from West-India seeds.
The usual mode of propogating it here, is by cuttings.

This species of _Mesembryanthemum_, so different in the shape of its foliage from all the others hitherto introduced into this country, is first described in the _Supplementum Plantarum_ of the younger LINNÆUS, from which we learn that it grew in the Upsal Garden, into which it was most probably introduced by professor THUNBERG, as on his authority it is mentioned as a native of the Cape of Good Hope.
Mr. ZIER, Apothecary, of Castle-Street, was so obliging as to present me this summer with the seeds of this curious plant, I sowed them in a pot of earth, plunged in a tan pit, whose heat was nearly exhausted; they quickly vegetated, and though the summer was far advanced, they proceeded rapidly into flower, and bid fair to produce ripe seeds, as the Capsules have long since been formed.
The whole plant is sprinkled over with glittering particles like the ice plant, to which it bears some affinity in its duration, being an annual and requiring the same treatment.
The blossoms are small and yellow, and if the weather be fine, open about two or three o'clock in the afternoon, the stalks are of a bright red colour, and the foliage yellowish green.
