HUTCHINSON—THE MADDENI SERIES OF RHODODENDRON, 71 
the species should prove hardy i in this country, although prob- 
ably susceptible to late spring frosts. It will no doubt be 
suitable for planting in the rock garden.

A tree 20 ft. high; one-year-old branchlets lepidote and 
with a few bristly hairs. Leaves obovate-oblanceolate or oblong- 
oblanceolate, obtusely mucronate and triangular at the apex, 
gradually narrowed from about the middle to an obtuse base, 
4.5-6.5 cm. long, 1.8-2.5 cm. broad, rather thinly and rigidly 
coriaceous, dull and glabrous above, densely lepidote beneath, the 
scales dark brown and less than their own diameter apart, the 
epidermis between the scales papillous ; midrib impressed above, 
prominent below, slightly lepidote ; lateral nerves about 6 on each 
side of the midrib, just visible below, the basal pair ascending 
acutely from the base; petiole 5 mm. long, widely V-shaj 
grooved in the middle, densely lepidote. Inflorescence 3-flowered, 
umbellate, the axis villous; pedicels about 3 mm. long, lepidote. 
Calyx small, about 1.5 mm. long, obscurely lobed, lepidote 
outside, not ciliate. Corolla small, about 4 cm. long, lepidote, 
nearly all over the outside, rather sparingly so on the tube and 
not at all towards the margins of the lobes ; tube a little shorter 
than the lobes; lobes 5, elliptic-rounded, with finely undulate 
margins. Stamens 10, a little longer than the tube; filaments 
pubescent in the lower }; anthers 4 mm. long. Ovary 5-celled, 
densely lepidote; style 3 cm. long, lepidote in the lower half, 
crowned by a lobulate stigma about 3 mm. wide. Capsule
