158 BALFOUR—NEW SPECIES OF RHODODENDRON. 
ash-grey indumentum as is seen on stems. Flowers in a shortly 
racemose umbel of some 12 flowers, rhachis puberulous ; fertile 
bracts submembranous oblong acute densely silky on both sides 
as much as 4 cm. long; bracteoles very short somewhat linear 
club-shaped hairy from the base and with a white hair-crest ; 
pedicels 3-4 cm. long densely tomentose inserted in middle of 
obliquely set-on calyx-base. Calyx saucer-shaped about 2 mm. 
long densely tomentose showing very short inconspicuous marginal 
teeth. Corolla cream-white with dark basal purple blotch about 
3.5 cm. long campanulate slightly oblique fleshy (‘‘ glutinous,”’ 
Ward) o-lobed ; lobes rounded emarginate imbricate about I cm. 
long 1.5 cm. broad. Stamens 18 unequal short little more than 
half the length of the corolla and shorter than gynaeceum ; fila- 
ments puberulous. Disk glabrous. Gynaeceum about 2.5 cm. 
long shorter than corolla ; ovary conoid grooved truncate about 
6 mm. long 1o-chambered densely tomentose with short besom- 
like hairs; style glabrous sometimes some hairs at its base 
expanded under the broad discoid lobulate stigma. 
N.E. Upper Burma. Lashi country. Htawjaw, valley of 
Naum-Chaung. Gnarled tree of 20-30 ft. as above 10,000 ft. 
Flowers rather glutinous, cream-white with dark purple blotch 
at base of corolla. Kingdon Ward. No. 1565. May 19, 1914. 
We know this plant only in a single specimen of Ward’s 
collection. It is one of the few species of the Falconeri series 
not yet in cultivation. 
The region of N.E. Burma and the adjacent one of Western 
Yunnan have added several species to the Falconeri series of 
Rhododendron. We have Rh. arizelum, Balf. f. et Forrest, 
Rh. basilicum, Balf. f. et W. W. Sm., Rh. megaphyllum, Balf. f. 
et Forrest, and Rh. preptum, Balf. f. et Forrest. Rh. regale gives 
us another. In S.E. Yunnan the series appears in Rh. sino- 
Falconert, Balf. f., and is represented in N.E. Yunnan in RA. 
Rex, Lévl., whilst in the N.W. region of Yunnan we have RA. 
jictolacteum, Balf. f., and Rh. coriaceum, Franch.—the latter ex- 
tending into S.E. Tibet. W. Szechwan gives us one species in 
Rh. galactinum, Balf. f. In all then ten species of this large- 
leaved series of Rhododendron have been made known within 
recent years from W. China and adjoining areas, more than 
double the number of those on record from Eastern Himalaya, 
where Hooker discovered Rh. Falconeri, Hook. itself, and Rh. 
Hodgsont, Hook. f., to which were added Rh. eximium, Nutt. 
and more recently Rh. decipiens, Lacaita, making the roll one 
of four species. Doubtless more members of the series will be 
discovered in course of further exploration in the wide area of 
the home of Rhododendrons, but as we have it now the Falconeri 
series is a remarkably illustrative example of the wealth in West
