He also published excellent illustrations of the cone and of the 
foliage. Franchet remarks that this species bridges over the 
difference between the Piceas or Spruces, and the Tsugas or 
Hemlocks. The leaf-structure, however, as described by Van 
Tieghem, in the ‘ Bulletin de la Société de Botanique de France,’ 
1891, p. 412, by Bertrand, in Ann. Sc. Nat. sér. V. xx. (1874), 
and by myself in the ‘ Gardeners’ Chronicle,’ in 1884, March 15, 
p. 348, and in 1887, April 9 (Abies Davidiana), by no means 
corresponds with the structure either of Picea or of Tsuga, but 
is much more like, though not quite identical with, that of Adces. 
This is one of the genera mentioned by Van Tieghem as possessing 
a resin-canal in the centre of the pith of the root. In addition 
to Keteleeria Davidiana, M. Franchet describes and figures a 
second species which he calls Pseudotsuga sacra, but this appears 
too closely allied to A. Davidiana to merit a separate name. 
Other species of the genus Keteleeria are represented in the 
Kew Herbarium by a specimen from the Hong Kong Botanic 
Garden (Ford, 386!), and by one collected by the Rev. E. Faber 
near the summit of Omei, Szechuan, and possibly by still another 
from Dr. Henry. 
ABIES. 
A classical name taken up by Tournefort and adopted by 
Linneus (1737). Great confusion has arisen from the different 
senses in which the names Abies and Picea have been employed 
by modern writers; it is, however, unnecessary to occupy 
space here with the discussion of this matter. Following Link, 
Bentham and Hooker and almost all European and American 
botanists now make Abies to include the Silver Firs, while Picea 
comprises the Spruces. The contrary custom is followed almost 
exclusively by English nurserymen, who have retained the 
arrangement proposed by D. Don, Loudon, and Gordon. The 
matter is referred to under the head of Picea (p. 28) and need 
not be further alluded to here. 
Abies, in the sense limited by Link and adopted by most 
modern authorities, comprises Abietinee with flat, spreading 
leaves which, in falling from the stem, leave circular scars with 
scarcely any swelling or pulvinus at the base. The male 
flowers are catkin-like, oval, or cylindrical, slightly stalked, the 
stalk surrounded at the base by perular scales. The anthers
