of the corolla is equally manifest and appears equally 
explicable. Certain minor differences, such as the presence 
or absence of a few hairs either on the basal portion of 
the style or on the apex of the ovary, are found to be as 
inconstant as the degree of development of the calyx- 
lobes, and to be uncorrelated with the variation in size 
and colour of the corolla, and Mr. Hutchinson has felt 
constrained on this account to include in R. concinnum, 
in addition to RF. yanthinum, not only the form described 
by Mr. Hemsley in 1907 as R. Benthamianum, but the 
still more distinct-looking L. coombense, figured at t. 8280 
of this work. It is to be noted that the form described 
as It. Benthamianum which is here referred to is not the 
plant so described in 1910. The latter differs from all 
the forms now included under &. concinnum in having a 
conspicuously spotted corolla and a more prominent 
areolation of the upper surface of the leaf. It has also 
to be remarked that while &. coombense is not distinguish- 
able from &. concinnum here figured by any valid morpho- 
logical feature, in its typical condition these two forms will 
probably always be treated as culturally distinct. In 
any case they constitute the extreme conditions of what 
is an exceedingly variable group of forms, and whatever 
their relative status may be, the one now figured is the 
most richly coloured and the most worthy of cultivation 
in that group. The plant from which our figure has 
been prepared was presented to Kew in 1908 by Messrs. 
J. Veitch and Sons, and was raised by them at Coombe 
Wood from seed obtained on their behalf by Mr. E. H. 
Wilson during one of his earlier Chinese journeys. Like 
all the forms included within it by Mr. Hutchinson, 
that now figured was collected in the neighbourhood 
of Ta-tsien-lu, in Western Szechuan. It is perfectly 
hardy and succeeds well in a light loamy or peaty soil.
