SERTULUM CHINENSE QUARTUM. 167 
Williams's plant is no doubt the one inaccurately taken for P. octandra, 
y Bunge, and referred with doubt by Maximowiez, in his * Index 
Flore Pekinensis, to Pireunia Laíbenia, Moq. I presume this latter 
is the same as Roxburgh's Phytolacca acinosa, of which he has given 
a very meagre diagnosis, but Moquin has entirely overlooked the name 
in his monograph of the Order, in the Prodromus.

Closely allied to the Japanese P. hastato-trilohum, Meissn., from 
which it differs by the glandular hairy peduncles, and the winged 
petioles. It is possible this may be the species mentioned by Maxi- 
mowicz as having been mistaken by Turczaninow for P. arifolinm, L.

remarkable little species, from its densely black-dotted foliage, 
something like which is described by Hasskarl (Plant. Junghuhn. 147) 
in 4. dion. Kth. It is not half the size of 4. nanum, and wants
