HuUTCHINSON—THE MADDENI SERIES OF RHODODENDRON. 45 
crowned by a fairly large deeply lobulate stigma. Capsule not 
nown. 
Described from a specimen in the Edinburgh Herbarium 
inscribed as follows: ‘‘ Rhododendron spec.? No. 7167. 
M*L. de Vilmorin. Chine. Cult. Verriéres, France, serre, 
19.4.18.” 
Unfortunately we have no definite information as to the 
habitat of this species. Professor Balfour says in regard to it : 
“ Raised from seed received in 1912 from China by M. Philip 
de Vilmorin. Most of de Vilmorin’s seeds came from N.E. 
Szechwan.”’ If this species came from this province, it will be 
a valuable addition to our gardens, as it would no doubt be 
fairly hardy, and is, moreover, almost a replica of the beautiful 
but somewhat tender R. ciliicalyx from Western Yunnan. It 
differs from R. ciliicalyx in its very bristly shoots and the 
denser leaf-scales. 
1g. Rhododendron missionarum, Léveillé in Bull. 
Geogr. Bot. xxiv. 20 (1915). 
A shrub with short knotty branches, the older parts covered 
with grey transversely splitting bark ; one-year-old branchlets 
very short, very slightly lepidote, strigose-pilose. Leaves 
obovate-oblanceolate, narrowed to the base, apex triangular- 
apiculate with a rather long callous mucro, 5—7 cm. long, 1.5-3 
cm. broad, rigidly coriaceous, lepidote above when young, 
soon becoming nearly glabrous and slightly reticulate, glaucous . 
and lepidote below, the scales slightly unequal and less than 
their own diameter apart, the epidermis densely papillous 
between the scales ; midrib and lateral nerves impressed above, 
the former prominent and lepidote below ; lateral nerves about 
8 on each side of the midrib, arcuate and ascending ; petiole 
6-10 mm. long, grooved above, lepidote. Inflorescence 2-3- 
flowered; floral bud-scales softly appressed-villous in the 
upper part; pedicels 6-10 mm. long, arising from about the 
same level, densely lepidote with flake-like scales. Calyx about 
I mm. long, obscurely 5-lobed, densely lepidote outside and 
fringed with stiff hairs about 1 mm. long. Corolla violet or 
white (Maire), 5 cm. long, not lepidote outside or rarely with 
one or two scales here and there; tube funnel-shaped, 2.5 cm. 
long, minutely pubescent towards the base outside; lobes 5 
2.5 cm. long and nearly as much broad, undulate on the margin 
and sometimes fringed with a few scales. Stamens 10, exserted ; 
filaments villous pubescent in the lower third; anthers 6 mm. 
long. Ovary 5-celled, 5 mm. long, lepidote; style curved, a 
little longer than the corolla, lepidote in the lower half or
