and shape of the calyx-segments vary a great deal, as does also- 
the degree of cohesion between them; for I find them sometimes 
united for half their length, and at others distinct to the base. 
The seeds have unfortunately dropped from my specimens. lt 
is clear that the two sections founded by Alph. DeCandolle are 
untenable; and, the Ochotsk species agreeing with the Japanese 
and North Chinese ones in the form of the corolla, and with the 
North American in the texture of the capsule and permanent 
calyx-limb, it seems impossible to separate these sectionally. 
The specimens I have seen vary so much in aspect that I am 
inclined to doubt whether A. DeCandolle's Weigela pauciflora is 
distinct. 
24. PYRETHRUM INDICUM, Cass., var.—]n collibus China borealis 
prope Ku peh kau, Sept. 1866, invenit Dr. Williams. 
The flowers of this are of a beautiful rose, whilst they are 
always yellow in the wild plant from the south; the leaves also 
are smaller; but I do not find any thing to denote specific dif- 
ference.

The opinion I expressed in the ‘ Adversaria,’ that A. patens, 
C. Wright, is identical with this species, has been fully con- 
firmed by Peking specimens received from Dr. Williams and 
Pére David, which entirely agree with the Formosa plant deter- 
mined in Mr. Swinhoe's published list by the late Mr. Alan 
Black as A. patens. It is very near the Indian 4. rotundifolia, 
Hardw.

This, Dr. Bretschneider states, on native authority, is used for 
rearing the wax-insect on. It looks different enough from the 
normal form, very well figured by Thunberg (Fl Jap. t. 1), 
which I possess from Nagasaki; but I have no doubt it belongs 
to the same species, respecting which Blume writes (Mus. Bot. 
Lugd.-Bat. i. 313), * Incredibile dictu, quanta hujus vel foliorum 
magnitudine forma et textura, vel inflorescentia minus magisve
