HUTCHINSON—THE MADDENI SERIES OF RHODODENDRON. 43 
walls, and there are good specimens at Tregye, Bosaham, Tre- 
mough, and Scorrier. In mid-winter, like nearly all Himalayan 
Rhododendrons, it withstands rather severe cold, but the young 
shoots which appear early in spring are readily nipped by late 
frosts. 
There are at least two fine hybrids: R. Victorianum, between 
R. Nuttalliiand R. Dalhousiae; and R. edinense, a cross between 
R. Nuttallit and R. Henryanum, the latter a hybrid of R. 
Dathousiae and R. formosum. 
ome interesting crosses will no doubt be possible in the 
future from R. Nuttallii and its nearer relations as shown in 
the present paper, especially the Chinese species, R. excellens, 
R. liliiflorum, and R. megacalyx (Burma).

A shrub 0.6-1.3 m. high, often procumbent on rocks (Clarke) ; 
older branches becoming smooth by the bark peeling off; one- 
year-old branchlets setose with long slender hairs and finely 
lepidote ; axillary leaf-buds still more or less dormant at the 
time of flowering ; young branchlets clothed for some time with 
the subpersistent bud-scales. Leaves elliptic or oblong-elliptic, 
rounded at the base, with a triangular obtusely mucronate apex, 
4-9 cm. long, 1.5-4 cm. broad, firmly coriaceous, setose with 
long rather weak hairs above especially when young, becoming 
glabrescent with age and slightly bullately reticulate, green and 
fairly laxly lepidote below, with a few setae only on the midrib, 
the scales small and about 2-3 times their own diameter apart 
(i.e. about one in the middle of each mesh of the network of 
veins), the epidermis somewhat pustulate between the scales ; 
midrib somewhat setose on both surfaces, prominent below ; 
lateral nerves about Io on each side of the midrib, diverging 
from it at an angle of about 45°, slender but distinct below ; 
petioles 5-7 mm. long, setose with long hairs. Inflorescence 2-4- 
flowered, very shortly racemose ; bud-scales apiculate, fringed 
with soft white hairs, only the outermost with a few scales on 
the back; pedicels about 1 cm. long, elongating to 2 cm. in 
fruit, densely setose and finely lepidote. Calyx well developed, 
5-lobed to near the base, 8-ro mm. long, lobes broadly ovate- 
rounded, nervose, densely fringed with long stiff hairs, sparingly 
lepidote outside towards the base. Corolla nodding, about 4 cm.
