riginal type in having hairy filaments ; that now figured 
differs orth all thies in having the filaments without 
hairs. This is a difference which, in the genus Lhodo- 
dendron, usually is specific; in the present instance 
it certainly does not possess that value. There is 
within &. argyrophyllum a fifth recognisable Be 
collected by Mr. Wilson on Wa-shan (Wilson, n. 121 ), 
which has glabrous filaments like those of vav. leiandrum, 
but has some of its calyx-lobes over one-third of an 
inch in length. The nearest ally of £2. argyrophyllum is 
ft. hypoglaucum, Hemsl., described at t. 8649 of this 
work, where the close relationship of the two species 1s 
discussed. The plant from which the flowering branch 
now figured was cut on 5 May, 1916, was raised from 
seed received from the Arnold’ Arboretum and sown in 
1909. This seed was collected in Western Szechuan in 
1908 by Mr. Wilson and was received as his n. 1353. 
This number, however, belongs in part to R. Wiltonii, 
Hemsl. & Wils., and it may be that in some collec- 
tions f. argyrophyllum var. leiandrum bears the name 
ft. Wiltonit. The plants at Kew are rounded, much 
branched bushes, now about afoot and a half to two feet 
high, slow of growth and sturdy. The species is appa- 
rently very hardy and did not suffer in the least from 
the severe winter of 1916-17, The flowers do not open 
until late April or early May, and thus have a better 
chance of escaping inj ury from late spring frosts than 
those of many of the new Chinese species.
