110 DL. II. F. HANCE’S SUPPLEMENT TO 
specimen of Dr. Thwaites's n. 1776, quoted by them under 
L. affinis, is certainly referable to L. trigona. L. chinensis, Lour., 
grows in half-dried ricefields, or in damp grassy plains, and is 
very abundant around Canton. It is perfectly glabrous, and 
nearest L. trigona, but differs by its almost or quite simple stem, 
sessile, oblong, or elliptic, entire, or slightly denticulate leaves, 
much like those of Z. anceps, Thunb. It is also of a deeper 
tint, and the upper leaves, terminal portion of the stem, pedicels, 
and calyx are most frequently of a purple tint. Loureiro de- 
scribes it as procumbent or creeping; but, though I have ob- 
served it for years, I have never seen a specimen otherwise than 
quite strict and erect, like a Striga.

The form and regularity or degree of irregularity of the co- 
rolla, the number of stamens, and the persistence or deciduous- 
ness of the foliage are so variously combined in different species, 
and there are besides some with only half-deciduous or nearly 
persistent leaves, that it appears quite impossible to admit the 
genus Azalea as circumscribed by Mr. Bentham and other bota- 
nists. Rhododendron as limited by G. Don (including Rhodora 
and Osmothamnus), seems to form a far more natural group. 
The genus, indeed, is in much the same case as Vaccinium, Ar- 
butus, Thibaudia, Andromeda, and other members of the family, 
which comprehend a variety of types linked to each other by 
different gradations, so that there seem no alternatives than 
either to regard each genus as a whole divided into a number of 
sections, or else to raise each of these to generic rank. The 
name Azalea should be reserved for the plant named Loiseleuria 
by Desvaux, and Chameledon by Link, which, as long 280 
observed by Hooker and Arnott, and Babington, is the original 
Azalea of Linneus (and therefore of course the type of the 
genus), and the only one to which the name is applicable T. 
f Since the above was written, I have received, through the kindness of the 
author, M. Maximowicz’s important memoir * Rhododendrez Asi orientalis, 
published at St. Petersburg in 1870. The author conclusively shows tha
