HUTCHINSON—THE MADDENI SERIES OF RHODODENDRON. II 
at the base, and the scales are more laxly disposed on the lower 
surfaces. Comparing with Dalhousiae, this distinct species may 
therefore be at once recognised by its fringed calyx and smaller 
flowers (see fig. 6). 
Now it is quite clear on consideration of the evidence before 
us that Fitch’s plate No. ii. is made up from a confusion of two 
species. Hooker’s original sketch of what he no doubt regarded 
as the real Dalhousiae shows the large flowered species with the 
glabrous calyx and the smaller obovate cuneate-based leaves, 
- typical of the species as known in our gardens. But unfor- 
tunately for the accuracy of his beautiful plate, Fitch must 
also have had recourse to the dried specimens: he draws faith- 
fully the large corolla of the real Dalhousiae, but has appended 
to it the large ciliate calyx of the other species, which I identify 
with the hitherto imperfectly known R. Lindleyi, T. Moore 
(R. bhotanicum, Clarke). The leaves, shown in the plate, are I 
think rather those of R. Lindleyi than of Dalhousiae; they are 
larger than any on Hooker’s sketch, and the glands are shown 
more laxly dispersed. 
In Hooker’s description accompanying the plate there is no 
mention of the hairs on the margin of the sepals, though they 
are shown clearly enough. But Hooker, himself, evidently 
brought the specimens of R. Lindleyi into his later descriptions, 
for in the Royal Horticultural Society’s Journal for 1852, p. 77, 
he describes R. Dalhousiae as having “ sepals oblong, blunt, 
hairy on the margin,’ whereas in the specimens of his typical 
Dathousiae they are quite glabrous. 
Hooker (Himal. Journ. i. 125) mentions Rhododendron. 
Dathousiae in his account of the ascent of Sinchul near Darjeeling. 
He describes the vegetation as follows: ‘‘ The purple-flowered 
kind of Magnolia (M. Campbellit) hardly occurs below 8000 feet, 
and forms an immense but very ugly black-barked sparingly 
branched tree, leafless in winter and also during the flowering 
season, when it puts forth from the ends of its branches great 
rose-purple cup-shaped flowers, whose fleshy petals strew the 
ground. On its branches, and on those of oaks and laurels, 
Rhododendron Dalhousiae grows epiphytically, a slender shrub, 
bearing from three to six white lemon-scented bells, four and 
a half inches long and as many broad, at the end of each 
branch. In the same woods the scarlet rhododendron (R. 
arboreum) is very scarce, and is outvied by the great R. argenteum, 
which grows asa tree forty feet high, with magnificent leaves 
twelve to fifteen inches long, deep green, wrinkied above and 
silvery below, while the flowers are as large as those of R. 
Dalhousiae and grow more in a cluster.”’
