LIST OF NEW PLANTS. 
Crassulaceve. —Dodecandria Dodecagynia. 
JEonium Youngianum. This plant, hitherto only known from a brief 
Latin description in Webb’s “ Natural History of the Canaries,” flowered in 
June 1843, in the nursery of Mr. Wm. Young of Milford, near Godaiming, 
after whom it was named by Mr. Barker Webb, who discovered it in the 
Canaries. It appears nearly allied to JEonium ( Semjtervivurn) arboreurn. — 
Bat. Reg. 
Ericaceae. — Decandria Monogynia. 
Andromeda phillyreeefolia. A very neat greenhouse shrub, introduced lately 
by Messrs. Loddiges, with whom it flowered for the first time in January last. 
It was originally discovered in West Florida by the late Mr. Drummond. 
One of the most striking characters in this very"distinct species is the peculiar 
darkness of its leaves, which thus are able to set off the snow-white flowers 
to great advantage : they look like pearls on a negro’s neck. — Bot. Reg. 
Oroiii j)acE iE. — Gynandria Monandria. 
Calanthe masuca. This charming plant was flowered by Messrs. Rollison 
in June 1843 : it is a native of Nepal, and may be regarded as the gayest of 
the terrestrial species of that rich country, being conspicuous both for the 
large size of the flowers and their fine colour. From the other purple 
species allied to it this is readily known by the leaves as well as by the 
flowers : C. versicolor has leaves smooth on both sides ; C. purpurea , downy 
on both sides, especially beneath; while this has down only on the under 
side ; C. versicolor has white sepals and petals, C. purpurea and this, purple 
ones. While, however, C. purpurea agrees in the colour of its flowers, its lip 
is altogether different, being very narrow, with the lateral lobes quite round, 
the contrary being the form of that of the present species. 
C. masuca should be potted in turfy heath-mould, mixed with a few pieces 
of potsherds : in summer it should receive an ample supply of water at its 
roots, and, where it can be avoided, little should be allowed to fall on its 
leaves, otherwise the young shoots will damp off. It enjoys a humid atmo¬ 
sphere and a high temperature; but as the leaves are very delicate, they 
will soon become scorched if shading is not carefully attended to. In winter 
little water will be required, but just sufficient to keep the bulbs from 
shrivelling. This is one of the most difficult of orchidaceous plants to grow 
well. — Bot. Reg. 
Rhamnace.e — Pentandria Monogynia. 
Ceanothus thyrsijlorus. A perfectly hardy shrub as this is, with evergreen 
foliage of the most beautiful glossy green and dense panicles of bright blue 
flowers, is indeed an acquisition to our gardens. In all respects this is one 
of the most valuable things that has been introduced for years. The country 
owes it to R. B. Hinds, Esq., who, while surgeon to the “Sulphur” surveying- 
ship, occupied himself with botany : he describes it as being common at San 
Fransisco and Monterey. It was also found by Douglas in California, where 
it forms a small tree completely loaded with dense masses of bloom. It 
flowered in the gardens of the Horticultural Society in May last, planted 
against a south wall. A considerable number of plants have been distributed 
by the Society under the name of C. divaricatus , which species it was at first 
supposed to be ; now, however, that it has flowered, it proves to be C. thyrsi¬ 
jlorus, and the first name has to be changed. — But. Reg.
