I do not feel satisfied that this is identical with Bunge's spe- 
cies, of which, so far as I am aware, only young specimens with 
d flowers have been described, which may account for several 
discrepancies. It seems well-marked by its fruit, the upper 
third of which is narrower than the base, aud the nut not at 
all elevated. 
29. Diospyros LOTUS, L. 
This shrub, recorded from the Peking mountains by Bunge, 
was met with by Mr. Sampson and myself in September 1866, 
unquestionably wild, in dense forests at the Tsing yune Pass, 
along the North River, about 120 miles from Canton. The only 
other localities where it is known to occur really indigenous are 
the Caucasian provinces, the Persian ones on the southern shores 
of the Caspian (Boiss. & Buhse, Aufz. Pfl. Transkauk. 146), and 
possibly the north of Asiatic Turkey. In the Dalmatian and 
Crimean stations it has probably subsisted from ancient cultiva- 
vation ; and Cxesalpinus, in the sixteenth century, speaks of it as 
an “arbor peregrina ” in Italy.

Aug. 1868, flf. invenit Rev. P. David. 
Found by Karelin in Turkestan, and by Schrenck in Songoria, 
but not hitherto recorded from China, nor has it been met with 
in Manchuria or Mongolia.
