G. Forrest, 6744 (Herb. Edin. !). 
This species, whose introduction to cultivation we owe to 
Mr. G. Forrest, is one of the prettiest foliaged plants of the genus. 
The very white undersurface of the leaves is conspicuous at some 
distance from the plant owing to the course of the leaves, those 
inserted on the lower side of the branchlet being directed forwards 
and upwards at the base and curving slightly backwards from 
about the middle, those on the upper side are twisted at the apex 
of the petiole to the sides, and also curve slightly backwards. 
The V-shaped groove is conspicuous but narrow. The terminal 
buds, as also the lateral, are short, rounded at the apex, pale 
pinkish-white, and heavily resin-coated. Branchlets in the first 
year are brown, glabrous, or with scattered erect short stiff hairs ; 
in the second year they are dark-brown. 
Transverse sections of the leaf show a well-developed con- 
tinuous hypodermis on the upper surface and on the lower side 
at the prominent midrib a 2- or in part 3-seriate hypodermis, 
2 lateral, sub-epidermal, medium-sized resin canals, a definite” 
endodermis enclosing a divided fibro-vascular bundle, a group 
of sclerotic cells on the lower side of the bundle, and usually 
1-3 such cells above. The leaf-margins are slightly recurved. 
Conclusions I. ae! aie s Franchet, is not in culti- | 
FE. The sank introduced as A. Delavayi from 
Szechuan should be known as A. Faber 
(Masters), Craib. 
Ill. The Yunnan plant introduced by Mr. G. 
orrest has been described as a new 
species—A. Forrestii, Craib.
