petiolus ad 4 mm. longus laxe lepidotus. Flores cerini ad 7 in 
umbellas veras parvas terminales inter ramulos foliatos sub- 
florales praecoces immersas aggregati inflorescentiae rhachi 
brevissima puberula; bracteae steriles sordide fuscae ovatae 
acutae coriaceae extus lepidotae intus adpresso - puberulae

prophylla lineari-clavata flavida supra dorso lepidota_ lanato- 
ciliata circ. 1.3 cm. longa calycem aequantia conspicua per- 
sistentia ; pedicelli circ. 5 mm. longi lepidoti. Calyx viridis

vel anguste ovatis obtusis extus intusque glabris margine lepi- 
dotis nunc setulis sparsis etiam ciliatis. Corollae longe tubulosae 
obliquae subcarnosulae circ. 2 cm. longae tubus ab axe florali 
paullo curvatus extus glaber intus sparsim pubescens sursum 
in lobos 5 circ. 6 mm. longos subellipticos integros basi latos 
infundibuliformi-ampliatus. Stamina 5 filamentis ad basim

recognoscenda. 
Szechwan ? 
This plant appeared in the Royal Botanic Garden, Edinburgh, 
in two or three specimens amongst a batch of Rh. Sargentianum, 
Rehder et Wilson raised from seeds in 1909 under Wilson’s 
number 1208. The seeds were the gift of Sir John Stirling 
Maxwell, Bart. of Pollok, who generously presented to the 
Garden his share of the spoils of Wilson’s exploration. By its 
growth and size and shape of leaf it is so different from 
Rh. Sargentianum that we have been prepared for something 
not of the type. Rh. Sargentianum has flowered freely during 
the past few years—this plant flowered in 1916 for the first 
time, and then some weeks before Rh. Sargentianum, producing 
small trusses of waxy white flowers with much longer corolla- 
tube than that of Rh. Sargentianum, and wanting entirely 
the coating of scales on the outside. The plant is very different 
from Rh. Sargentianum. I do not know if it has turned up 
elsewhere in cultivation.
