elder Hooker included in the genus Aralia the Rice- 
paper Plant of Japan, figured at t. 4897 of this work 
as A. papyrifera, Hook., and in the Genera Plantarum 
Bentham and Hooker have followed the elder Hooker in 
treating these two as congenecric, admitting, however, 
that they cannot be treated as species of Ara/ia. In 
1859, however, C. Koch had come to the conclusion that 
Avalia papyrifera is also entitled to be considered a distinct 
genus to which he gave the name Tetrapanar. The 
genus to which Bentham and Hooker have referred the 
species whereon the genera Lehinopanar and Tetrapanax 
-were based is Futsia. But, in his careful revision of the 
Araliaceae, Dr. Harms has advanced reasons for con- 
sidering that both Tetrapanar and Echinopanax are quite 
distinct from J uatsia, a conclusion with which, after 
further study of the group, Mr. Rolfe finds himself in 
accord. Lehinopanax horri'us is a native of the coast 
and islands of North-west America, from Sitka and the 
Charlotte Sound to the Oregon, the borders of California 
and the Rocky Mountains. The species occurs again in 
Japan, where it is known as Ari Bouki. A figure is 
given in the thirtieth volume of the standard Japanese 
work, Phonzo Zoufou, at folio 12, recto. Nakai has 
recently announced the existence of an Echinopanax in 
Corea, which he has described as £. elatus, and as 
differing from £. horridus in having umbellate in place 
of racemose umbellules. Although Z. horridus is very 
hardy, in so far as being capable of enduring severe cold 
is concerned, it has never been a success in the open 
ground at Kew owing to its habit of starting early into 
growth in spring under the stimulus of what, to it, is 
unseasonable warmth. This early growth is almost 
always destroyed by subsequent frost. The plant from 
which our plate was prepared was purchased from the 
nursery of the Messrs. Lemoine in 1909. Since then it 
has been planted in the open ground, but covered by @ 
glass frame through the early spring months. Under. 
this treatment, which affords sufficient protection to its 
young leaves, it has made a healthy plant, striking for 
its fine foliage and formidable armature. In the coast 
forests of North-west America the entangled prickly 
stems are described as a serious impediment to. travel
