This is doubtless identical with the plant found by Maximo- 
wicz along the Ussuri. It agrees well with Zuccarini’s diagnosis, 
and is considered by Miquel identieal with the Japanese plant. 
There can be no doubt, I think, of its perfect distinctness as a 
species.

I have not seen the Indian plant; but this agrees very well 
with DeCandolle's diagnosis and Wight's plate (Ic. Pl. Ind. Or. 
ii. t. 571). It may be the “genus novum affine Dasyloma ” 
(sic) of Maximowiez's ‘Index Fl. Pekinensis? Another species 
of the same section, which is apparently the same as Miquel's 
D. japonicum, has been gathered by Mr. Sampson in waste places 
around Canton. In this the umbels ave usually about 15-rayed.

River, prov. Cantoniensis, locis eluvionibus obnoxiis, m. Junio 1865,

Ido not happen to possess European specimens ; but Mr. Samp- 
son's plant agrees quite well with Koch's diagnosis and with the 
careful description in v. Wul:en's ‘Flora Norica phanerogama.’ 
This is another instance of the southward extension of North- 
east Asiatie plants to which I have already called attention, the 
species being recorded from Northern China, Davuria, and the 
Amur and Ussuri territories.

Prof. Asa Gray remarks that D. Middendorffana has a thin 
capsule (it is described as coriaceous in the ‘ Florula Ocho- 
tensis"), by which character and by the persistent calyx-limb 
it shows an affinity to the American species, though very dif- 
ferent in the form of the corolla. The North-Chinese plant, 
however, with its rigid indurated fruit and deciduous calyx-limb, 
agrees entirely with the Japanese species, especially D. flori- 
bunda as figured by Zuccarini (Fl. Jap. t. 32. fig. 8). The size
