This is certainly one of the most splendid plants of recent introduction, and as 
it blooms most freely throughout the greater part of the year, a finer ornament to 
our conservatories can scarcely be conceived. 
It is a native of Java, where it occupies various localities in the dense forests, 
four thousand feet or more above the level of the sea. It was originally discovered 
by Blume at the foot of Mount Salak, where it was called by the natives Gaga 
Mirha : it was named by that botanist Vireya Javanica, in honour of M. Virey, a 
French physician ; but the differences in the construction of the flowers of this 
genus and Bhododendron, appear too slender to admit of its being satisfactorily 
established as a new genus ; these differences merely consisting of the stamens 
being in no way adnate to the corolla, and the calyxes being unusually small. We 
have therefore considered it a species of Rhododendron. 
There are several varieties of this fine species known in Java, differing chiefly in 
the pale yellow or deep orange of the flowers ; one of a smaller growth and of a pale 
citron colour was noticed and described by Blume, and another of a fine orange-
