pedicels short; calyx small, five-parted. . Coroixa oblique at the 
base; tube short; limb spreading, five-lobed, lobes obtuse or slightly 
emarginate, the inner side a most delicate pink, except where it is 
marked with deep red spots at the base, and reddish spots on the upper 
lobes. STAMENS ten, unequal in length. ANTHERS two-celled. 
Ovary five-celled. Sty.te one. Stiema capitate. 
Popotar AND Grograpuican Notice. The parents of this hybrid 
were the Rhododendron arboreum, a native of Nepal, on the moun- 
tains of Narainhetty; (the varieties Rhododendron arboreum roseum, 
and Rhododendron arboreum niveum, are found only on Sheopore, 
at the head of the valley of Nepal, occupying a station on that moun- 
tain 10,000 feet above the level of the sea); and the Rhododendron 
Caucasicum, which grows on the highest of the Caucasian range of 
mountains, bordering on the regions of perpetual snow. The pro- 
duction of hybrids has been objected to on the ground that they lead 
to confusion among species. They are, however, far from being 
useless, as they illustrate many points in physiology, particularly with © 
regard to the origin and permanency of certain varieties or races— 
both human, and in the domestic animals; and also modify the con- 
stitution of plants in a very remarkable degree. The magnificent 
Rhododendron arboreum, though growing at such an elevation in its 
native land, has been found too delicate to endure our climate in the 
open air, Various hybrids, produced by applying the pollen of it to 
some other species, have been found hardy enough, and as the flowers 
are little less splendid than those of the Tree Rhododendron itself, our 
woodlands and heaths are now adorned with most magnificent tufts of 
flowers in the early part of spring. Of this, Lord Carnarvon’s seat, at 
High-Clere, i in Hampshire, is a striking instance—the hybrids which 
flourish there, however, are produced by fertilizing Rhododendron 
e Catawbiense with Rhododendron arboreum. 
_  QOricin; WHere Grown; Cotrore. This mule originated with 
Mr. William Smith, of Norbiton Common Nursery, near Kingston, 
Surrey. The specimen from which our drawing was made, flowered 
with Messrs. Rollisson, Tooting. It requires the usual bog-earth soil.
