472 BOTANICON SINICUM. 
Cu‘en Ts‘anc-K‘t [8th cent.]:-—All the various sorts of 
the po tree have a yellow bark, and likewise the siao po which 
resembles the pomegranate. It has red fruits like those of 
the kou k% [Lycium. See 345], pointed at both ends. The 
people cut off the branches and use them for dyeing yellow. 
Su Kune is wrong in stating that the berries of the siao po 
are black and round. He had probably another plant in 
view. 
Lt Sut-cen :—The siao po is a small mountain-tree. 
Its outer bark is white and the inner bark yellow like 
that of the po, but thinner. The name shan shi liu is also 
applied to the kin ying tsz‘ (a Rose) and the tu yiian hua 
[Rhododendron. See 155]. 
The siao po is not figured in the Ch.—The name ill BE 
is given there [XXXVII, 43] as a synonym for 7% i& 7 
huang lu mu. The figure, a spiny tree, is possibly intended 
for a Berberis, .

dye.
