more perfectly lovely than this. Its leaves, of the richest and 
deepest green, mellowed by the warm tone of their under surface; 
its large clusters of bell-shaped flowers, hanging loosely, yet com- 
pactly, by their slender stalks; and the half-transparent snowy 
corollas ; form together an effect which few objects could rival, and 
none surpass.” (Bot. Reg., July, 1834.) This variety and R. a. 
roseum, as already remarked, are found at an elevation of 10,000 ft. 
above the level of the sea; and Dr. Wallich states that they are 
confined to the single mountain of Sheopore: 2. a. roseum is 
there by far the most common variety. He says, “ They attain the 
size of very large forest trees, and are noble objects at all times. 
They blossom simultaneously in April, in which state their beauty 
surpasses description, the ample crown of the trees being entirely 
covered with bunches of large and elegant blossoms,” The common 
red-flowered, or parent, species (?. a. sanguineum ) is also found on 
Sheopore; but it is less frequent there than in lower situations, 
where it blossoms a month earlier than the varieties. The hardiness 
of the varieties of any species being proved, affords a presumption 
that the species itself is only accidentally tender, and that, after 
some generations, it may become hardy. 
2 R. a. 4 cinnamémeum; R. cinnamomeum Wall. Cat., No. 760., and Don’s 
Mill., iii. p. 384.; has the leaves clothed with an intense rusty to- 
mentum beneath; and corollas like those of 2. a. niveum, but not 
of so clear a white, and spotted with brown instead of purple, It 
was introduced from Nepal in 1817, and flowered for the first time 
in the Chelsea Botanic Garden in 1832. 
2 R. a. 5 venistum D.Don, Brit. Fl.-Gard., May, 1835, 2d ser., t. 285., 
is a hybrid, and an exceedingly showy and interesting plant. It 
was raised by Mr. Wm. Smith, = Ge) 
nurseryman, Norbiton Com- NS 
mon, near Kingston, Surrey, 
from seeds of 2. caucdsicum, \ 
that had been fertilised by 
the pollen of &. arboreum, 
and appears hardier than the 
species. 
Other varieties and hybrids of R. arboreum 
and other half-hardy species may be found in 
the nurseries, some with and others without 
names; some of them rather tender, and others, 
such as R. a. altaclerénse (fig. 952.) quite hardy 
or nearly so. The names of several new va- 
rieties will doubtless appear in the nursery- 
men’s catalogues, and in the botanical periodi- 
cals, before this work is completed: for there 
are many hundreds of seedlings of #2. arbdreum 
fertilised with hardy species; and hardy species 
fertilised with &. arbdreum, in Knight’s 
Exotic Nursery, in the Norbiton Common Y 
Nursery, and in various others, which are now (Sept. 1, 1836) showing blossom buds for the 
first time, Many of these hybrids will appear, be recorded, and afterwards, when they are sup- 
planted by others of still newer origin, lost,

Spec. Char., §c. Leaves elliptic-oblong, mucronate, rusty beneath, rather 
cordate at the base. Segments of corolla flat, emarginate. Ovarium 
6-celled, glabrous. Under surfaces of leaves clothed with fine scaly pu- 
bescence, at first of a purplish hue, then changing to nearly white, 
and afterwards to a deep ferraginous brown. Flowers copious, disposed 
in corymbose clusters. Pedicels glabrous. Bracteas fringed. Corollas 
large, pale pink, changing to white, having the upper lip marked with 
irregular purple spots. Filaments bearded at the base. This species 
surpasses all others in the size of its flowers, except one found in Java by
