station at Langkiung, where Forrest has also collected it is its southern limit; 
thence it spreads north and north-east over the Likiang Range to the Chimgtien 
Plateau, and also to the Mu-H Mountains in S.W. Szechwan, but it also has a 
remarkable range to the north-west over the Kari Pass and the Mekong-Yangtze 
divide into the Mekong-Salween divide. Our knowledge of all this further 
distribution we owe to Forrest. The specimens of it obtained over its wde 
area show some variation in dimensions of the rugulose leaf, narrow and broad, 
short and long, but so far as evidence in foliage-specimens offers only one species 
is decipherable showing these forms. The strong diagnostic character of the 
species which all these forms possess is that of the underleaf indumentum. 
The hairs of the upper stratum which give the cinnamon-colour to the surface 
are somewhat broad open funnel-shaped cups with a polygonal outhne raised on 
longish many-celled stalks. The cup-wall is thin, of large nearly isodiametric 
cells, and its undulate margin is lobed, each lobe prolonged into branched hairs, 
whilst the intervals between the lobes are somewhat concave. The features are 
most characteristic and enable one to recognise the species without difficulty. 
It is upon this character that the specimens without flower or fruit have been 
identified. The flower-truss has some 20 flowers, each flower with a white 
8-lobed corolla slightly cream-tinted and with a large basal crimson blotch sur¬ 
mounted by fainter crimson spots, 16 stamens with puberiflous filaments, and 
an 8-10.-chambered ovary coated outside with a tomentum of short-stalked 
hairs not densely aggregated, each putting out from the summit of the stalk many 
loose branches, the whole hair somewhat resembhng a pollard wllow. Of 
where to place this species in the Falconeri Series I am uncertain. It has finks 
with several, and yet differs from all. Perhaps the species least divergent is 
R. SINOFALCONERI.

[sjy«. R. LACTEUM, Rehder et Wilson, PI. Wilsonianas I (1913) 545 in part]. 
In 1916, when writing in the Transactions of the Botanical Society of 
Edinburgh, about R. lacteum and R. fictolacteum, I pointed out that 
Wilson’s No. 4254, which was placed—with a suggestion of doubt—by Rehder 
and Wilson, under R. lacteum, Franch., in Plants Wilsonian^, could not be 
that species. The plant was collected by Wilson in October, 1910, at an elevation 
of 3,000-3,300 m., in woods of Pan-lan-shan, west of Kuan Hsien, in Western 
Szechwan. Wilson obtained his plant in fruit only, and man^^ plants have been 
raised from seed collected by him. My expectation that Wilson’s plant would 
prove to be a new species was based upon the examination of the underleaf 
indumentum of young living plants. As the plants have grown the leaf- 
characters support the view that we have here a distinct species. Indeed, so 
evident is the difference in appearance of Wilson’s plants and other members of 
the Falconeri Series that there is no doubt in my mind over the question of 
specific distinction. Christening of it here is a transgression of a canon which 
discourages the botanical naming of plants known in foliage onty, and if I sin it 
is because the name affords the simplest method of replying to enquiries as to 
the identity of Wilson No. 4254, and also of stifling at the outset the naming of 
it as “ R. LACTEUM ? ” and “ R. fictolactuem ? ” a practice which is certain
