DR. H. F. HANCE ON NORTH-CHINA PLANTS. 75 
ing plants collected by Dr. Tatarinow and others) To these I 
have added a few species which, previously recorded only from 
the north of the empire, have recently been detected in the ex- 
treme south, the majority of them by Mr. Sampson. In con- 
nexion with the two latter categories of plants, I have essayed 
to impart a geographical interest to an otherwise bald enume- 
ration, by mentioning the nearest localities previously known. 
It is scarcely possible for a botanist quite isolated from scientific 
society, and restricted to his own limited collection of books and 
plants for the requisite data, to avoid errors and omissions in 
such a record ; and for all such as may exist in this brief paper, 
I ask the indulgence of naturalists more happily situated for 
purposes of study than myself.

l. CLEMATIS (FLAMMULA) TUBULOSA, Turcz.?—]n umbrosis col- 
lium ab urbe Peking occidentem versus, Augusto, 1866, coll. Dr. S. 
W. Williams. 
I have little doubt that Dr. Williams's plant, which he de- 
scribes as “a coarse vigorous annual, with rank-smelling purple 
flowers," is referable to this species, only known to me, however, 
from Walpers's * Repertorium ;’ but if so, Turezaninow's diagnosis 
is not satisfactory. In the Peking specimens, the lower leaves 
are trisect, the upper trilobed only, or merely irregularly slashed, 
usually sparsely hairy, and prominently reticulate ; the cohesion 
of the sepals, though evident, is very slight, and at full anthesis 
they become free to the base; the anther is scarcely longer than 
the filament; and the flowers are apparently polygamous ; for in 
the same corymb I find both staminal flowers, and pedicels from 
which the calyx has fallen, surmounted by the plumose ovaria. 
From Ku-pei-kaú, growing in dry places along roadsides, I have, 
also gathered by Dr. Williams, a plant with hermaphrodite blos- 
soms, solitary and long-stalked, or arranged in a few-flowered ra- 
ceme, each flower borne on a pedicel an inch or more in length ; but 
the foliage and calyx are so similar that I do not doubt its being 
a mere variety of C. tubulosa. This approaches somewhat to the 
rare C. stans, S. and Z., which is unquestionably the nearest ally 
of Turezaninow's species; but in that the flowers (which are 
doubtless also polygamous, not strongly dicecious) are more than 
twice as small, short-stalked, and arranged in 2-3 distant clusters, 
forming a raceme. As the sections are limited in the * Flora In-
