however, is now found to deserve separate recognition. 
For the plant in question, Mr. Brown suggests the name 
R. elata. It is characterised by being twice as large as 
R. angulata; by having leaves with 2-6 acute entire lobes 
on each side in place of having either very many marginal 
teeth, or, if there be a few lobes or large teeth, by these 
being again toothed; by having bracts or flowering leaves — 
with long cuneate bases not broader than the lamina nearer 
the apex, as against very broadly and rather abruptly 
cuneate bases which are wider than any other part of the 
lamina. The corolla in £&. elata is slightly larger and is 
bright soft rosy purple on the lips, yellow dotted with red 
in the throat; in R. angulata the rather smaller corolla is 
red with a band of scarlet at the margin of the upper lip 
and has orange dots inside the lower lip. The species now 
figured is in somewhat like case; it has hitherto been 
treated as a form of R. Piasezkii, Maxim., a native of the 
northern parts of Shensi, which differs in being over 3 ft. 
high, and in having subsessile bracts or flowering leaves 
and purplish flowers. 
Originally discovered by Mr. A. Henry about 1885 in 
the neighbourhood of Ichang, and subsequently collected 
by him near Nanto, R. Henryi was again met with by 
Mr. E. H. Wilson somewhere in the same general region. 
A share of the seed obtained by Mr. Wilson was com- 
municated to Kew, in 1907, by the Director of the Arnold 
Arboretum, Jamaica Plain, Mass. Plants raised from this 
seed grew well under ordinary greenhouse treatment, and 
flowered in 1908 and again in 1909, when the figure 
now given was prepared. The species sets seeds freely, 
and it may prove hardy in the warmer parts of England.
