10, inclosed, unequal, declinate. Filaments awl-shaped,
white, copiously bearded at the base. Anthers brown, of
2 parallel connate cells, opening by 2 terminal, round foramina.
Ovarium oblong, conical, 6-sided, 6-celled, glabrous,
seated on a flattish angular disk, of a glaucous green,
dotted with white. Style declinate, filiform, pale-green,
projecting beyond the corolla, club-shaped at the top.
Stigma annulate, with an elevated, G-lobed, papillose disk.
This splendid species of Rhododendron is a native of
Gosaingsthan, a high mountain, to the north of the valley
of Nepal, and was introduced to the gardens about ten
years ago, from seeds communicated by Dr. Wallich. The
flowers are of a milk white, shaded with lilac, and surpass
in size all others of the genus, with the exception of one
discovered in Java, by Dr. Horsfield, the dimensions of
whose corolla are still greater. It was originally taken up
by me from specimens sent by Dr. Wallich, and preserved
in the Lambertian Herbarium. It is truly arborescent,
although of much smaller dimensions than arhoreum, and
being found at a higher elevation, it is to be presumed that
it will prove hardier than that species. I t will be found to
succeed well in a soil composed of two parts of sandy peat,
and one of meadow loam, and it may be increased by
layers, or by seeds.
Our drawing was taken from a fine healthy plant, which
blossomed in Mr. Knight’s choice collection, in April last.
It is remarkable, that India should possess the maximum
of the typical species of this genus, while in China and
Japan, is found a group connecting these with the pentan-
drous species of North America.
The generic name will be found explained at fol. 10.
