Ttubus palmatus is a very elegant species, differing from 
the typical forms of the genus in the elliptic shape of its 
white spreading petals. It has several allies in Japan and 
China with similar flowers, especially 2. incisus, Thunb., 
which differs in its leaves being only 3-lobed, and in the 
tomentose inner surface of the calyx-lobes. Thunberg’s 
figure of palmatus is excellent; De Candolle has doubtfully 
referred it to Lt. microphyllus, Linn. f., also a native of 
Japan, which has recurved prickles, and a villous calyx. 
‘The plant of £. palmatus, from which the accompanying 
figure was made, was obtained from Messrs. Veitch & Sons, 
of Chelsea, in 1899. It is now twenty feet high, trained 
against a pillar in the Himalaya wing of the Temperate 
House of the Royal Gardens, Kew, where it flowered in 
April of this year. There are specimens of it in the 
Kew Herbarium from Yokohama, N agasaki, and the 
central mountains of Japan, ascending to seven thousand 
OctoBER Ist, 1901.
