where, as Mr. H. White informs us, it has more than 
once experienced very severe frost, but has escaped with 
only slight injury; and at Kew where an example which 
has lived out of doors for five years is quite healthy. 
_In cultivation it has so far grown into a compact shrub 
about three feet high, bearing some outward resemblance 
to R. campylocarpum, Hook. f., figured at t. 4968 of this 
work; its nearest ally, however, is R. Souliei, Franch., 
described at t. 8622. Marked features of R. callimorphum 
are its long petioles covered with red or blackish stalked 
glands, and its nearly cordate ovate-orbicular leaves with 
a distinct bloom on the underside. Occasionally one of 
the uppermost leaves is considerably reduced in size and 
spathulate in shape, while the petiole is widened and 
winged. It is not clear that this is a frequent feature 
in f. callimorphum; it arrests attention owing to its 
rarity in species of Rhododendron proper, though it is of 
common occurrence in the Azalea section of the genus. 
It is perhaps too soon to predict the situation that will 
best suit 4. callimorphum and lead to its attaining the 
dimensions of wild specimens. Those in shady positions 
are, however, at present growing more freely than those 
in fairly open spots. _ 
Descriprion.— Shrub, in nature reaching 10 ft. in height, laxly leafy ; twigs 
rather straight, cylindric, becoming brown towards the base and nearly.

save for some stalked glands on the midrib, which is prominent and usually 
reddish beneath; lateral nerves about 8-9 along each side, freely branched 
towards the leaf-edge; petiole 1-8 in. long, sparsely beset with reddish or 
blackish stalked glands. Injlorescence terminal, about 8-flowered; bracts early 
caducous, not yet seen; pedicels spreading, 3-1 in. long, densely beset with red 
short-stalked globular glands. Calyx very short, about zs in. long; lobes 5,
