other side of the South American continent \ This is a small tree, ten to twelve feet high, com- 
mon on the banks of all the small rivers in the Organ Mountains. Tab. 1837.' The plant here 
figured thus makes a third clearly defined white-flowered shrubby Datura. It merely requires the 
protection of a cool greenhouse. In the summer it succeeds best in the open air, and bears its 
fine blossoms at that period." — Bot. Mag., 4252. 
Diaste x ma ochroleu'ca. " A very pretty and ready-flowering Gesneriaceous plant, of which 
tubes were sent to the Royal Gardens of Kew by Mr. Purdie, from the Sierra Nivada of Santa 
Martha, New Grenada. It is evidently nearly allied to Achimenes, and apparently identical with 
Mr. Bentham's Diastema (8iacrTr]fJ.a, intervallum, in allusion probably to the genus being inter- 
mediate between Achimenes and Gesneria), of which he remarks, * the free stamens of this plant 
indicate an affinity with Achimenes, and the form of the corolla is not unlike that of some of the 
small-flowered species of that genus, but the tube is neither gibbous nor spurred at the base, and 
the five equal perigynous glands are more prominent even than in Gesneria and Gloxinia. It is 
not improbable, however, that A. erinoides, D.C., and A. conifera, D.C., may be congeners of our 
plant.' It flowered in August, 1846, and requires the heat of a stove." The plant is erect- 
growing, has opposite, hairy, ovate leaves, and bears terminal panicles of straw-coloured flowers, 
about the size of those of Achimenes coccinea. — Bot. Mag., 4254. 
Holbo'ilia latifo'lia. Dr. Lindley states : — " For the opportunity of figuring this rare plant, 
we are indebted to L. W. Dillwyn, Esq., of Sketty Hall, near Swansea, with whom it flowered, 
perhaps for the first time in Europe, on a south wall, without protection, in the beginning of last 
March. Other plants, in the stove and conservatory, have shown no disposition to blossom. If 
only as a new hardy or half-hardy climber, it is a plant of interest, notwithstanding the greenness 
of its flowers. But it is sweet-scented. Mr. Dillwyn informs us that the female blossoms have a 
faint, sweet smell, such as is common in flowers of the same colour ; but this smell is infinitely 
more powerful in the males, which, towards sunset, fill the air, in favourable weather, for several 
yards around, with a delicious perfume. The latter appear later than the females ; there was full 
ten days between the first opening of the two sexes." According to Dr. Wallich, this species 
sometimes attains naturally a gigantic size ; he writes : — " Its leaves are broad, ovate, either 
ternate, or quinate, about as long as the common petiole ; the flowers are quite white, collected 
in clusters ; the berries large and ovate, the seeds oblong." Synonyme, Stauntonia latifolia.

Hydra'ngea japo'nica, var. c^eru^lea. " For the introduction of this Hydrangea to European 
gardens, the botanic world is indebted to Dr. Siebold, who found it wild on the island of Nipon, and 
abundantly cultivated by the Japanese. Two varieties are distinguished by that eminent Japanese 
traveller ; ( Benikaku,' with rose-coloured flowers, and ' Konkaku,' with blue flowers. The 
former state of the plant is figured by Siebold, and Dr. Lindley ; our plants, the gift of Mr. Knight, 
of the King's Road, Chelsea, and of Mr. Henderson, of Pine-apple Nursery, Edgware Road, happen 
to be the blue-flowered variety, and infinitely the handsomer of the two. Whether this variety is 
permanent, or, as many suspect, depending upon cultivation and the nature of the soil, and there- 
fore liable to change again, I am unable to determine. It succeeds with the same treatment as the 
Hydnragea hortensis, and will probably soon become as common as the blue-flowered kind, and as 
great a favourite." — Bot. Mag. 4253. 
Ionopsi'dium acau'le. " This charming little annual was received by the Horticultural Society 
from the garden of the Due de Palmella, near Lisbon, in March, 1845. The following account of 
it has been published in the Journal of the Society :— e It is found wild, according to Brotero, on 
the basaltic hills near Lisbon, and occasionally on the limestone formation of Estremadura. 
Desfontaines also met with it in Barbary. A hardy plant, with small cordate leaves, and flowers 
which are at first white, turning to a pale lilac, growing in any rich garden soil, and blooming from 
April to October ; requires a shady situation, and is suitable for an edging and for rockwork.' "

Jas'minum nudiflo n rum. " Here we have another," writes Dr. Lindley " of the interesting- 
plants introduced from China by Mr. Fortune." In the Journal of the Horticultural Society, it is 
stated to be "a shrub with angular deep-green trailing branches, which have little disposition 
to branch in the first year of their growth. The leaves are shining, deep-green, and each consists 
of three sessile leaflets, of an ovate form. They fall off early in the autumn, soon after which they
