152 BALFOUR—NEW SPECIES OF RHODODENDRON. 
glandular-ciliate. Corolla tubular-campanulate white or white 
flushed rose, not spotted, about 2.5 cm. long, outside glabrous ; 
tube inside densely pubescent eglandular ; lobes rounded crenate 
emarginate, about 1.5 cm. long by 2 cm. broad, often much less, 
more or less erect. Stamens 10 unequal, longest as much as 
2.2-3 cm. long, shortest about 1.5 cm. long; anthers 2.5-3.5 mm. 
long ; filaments somewhat abruptly flattened and broadened at 
base and there densely whitely pubescent to a little above ovary or 
higher, above that glabrous. Gynaeceum about equalling longest 
stamens ; ovary 5 mm. long, in smaller flowers 3.5 mm. long, 
conoid grooved densely glandular, glands clavate and stalked 
mixed with branched more or less rufous hairs ; style glandular 
through more than half its length, glands orange-coloured and 
stalked, mixed with some branched twisted hairs, apex of style 
clavate not much expanded into the lobulate stigma which is 
no wider than the style.

So far as Léveillé’s description goes, there is nothing by 
which to distinguish his species Rh. cruentum from Rh. Bureavi 
and other members of the Edgeworthii series. M. Léveillé has, 
however, been so kind as to present a portion of his type RA. 
cruentum to the Herbarium of the Royal Botanic Garden, 
Edinburgh, from which I have learned what was before him 
when he diagnosed his species, The plant is the same as one 
of which we obtained specimens from Abbé Maire in 1913, and 
from this materia] and M, Léveillé’s gift I have drawn up the 
description given above. 
Rh. cruentum is a very near ally of Rh, Bureavi, Franch., but 
shows divergences which forbid its inclusion in that species. 
The foliage and shoots are quite alike in the two species, 
and are most characteristic in their red thick indumental cover- 
ing—only in Rh. cruentum the leaves do not appear to reach 
the size of those of Rh. Bureavi, and the petioles are thinner and 
longer. The most easily seen distinction between the species 
is the calyx. In Rh. Bureavi the calyx has large membranous 
lobes with flabellate veins, and the tomentum is mainly formed 
at their base. In Rh. cruentum the calyx-lobes are much smaller, 
thick and leathery, and their outside surface is covered all over 
with the indumentum. Another apparently good diagnostic 
character is the style, which in Rh, Bureavi has at the base
