166 SERTULUM CHINENSE QUARTUM. 
sepalis zequalibus oblongis acutis bilinealibus, corolla calycem duplo 
excedente, genitalibus inter se equalibus, corolle medium attingenti- 
bus, stigmatis cruribus brevibus complanatis.—In planitiebus herbosis 
Mongoli:x citerioris, m. Sept. 1867, invenit Dr. S. W. Williams. (Ex- 
siec. n. 14690 
A curious little plant, of whose precise affinities I am uncertain. 
C. arvensis, L. var. sagittifolius, Turcz. exhibits, though in a much 
less degree, pellucid markings in the leaves; but our species is at once 
distinguishable by its dwarf size, exauriculate leaves, short peduncles, 
acute sepals, and (so far as I could make out from examination of a 
single flower) broad obtuse stigmas. The flowers seem pinkish, but 
as blue Convolvuli dry of this colour, their hue when fresh is uncertain. 
Dr. Williams seldom saw a specimen more than a foot long, and it is 
frequently much smaller. The same gentleman found C. Ammanni, 
Desr., and C. £ragacanthoides, Turcz., near Kalgan or Chang-chia-kaü, 
nds the Great Wall. 
6. Dracocephalum (Boguldea) rupestre, u. sp.; caule adscendente 
vilous foliis radicalibus et caulinis petiolo iis zequilongo vel parum 
reviore suffultis oblongis obtusis crenatis e basi cordata in petiolum 
euneatim attenuatis utrinque pilosis subtus pallidioribus, floralibus ses- 
silibus e basi cuneata ovatis serratis, verticillastris circ. 8-floris capi- 
tuliformibus, bracteis euneato-rhomboideis longe setaceo-serratis caly- 
cibus paulo brevioribus, calycis dente supremo obovoideo reliquis 
linearibus subtriplo latiore omnibus acutissimis, corolla ampla rubes- 
cente calyce duplo longiore, antheris glabris.—In rupibus editis ditionis 
Pekinensis invenit Rev. A. David, miss. apost. (Exsice. n. 14881.) 
This plant, which is probably the unnamed species mentioned in 
Maximowiez's ‘Index Flore Pekinensis,’ is intermediate between .D. 
altaiense, Laxm. and D. grandiflorum, L. (chamedryfolium, Fisch. et 
Bth.) 
7. Phytolacca Pekinensis, n. sp.; foliis basi cuneatis oblongis v. 
obovato-oblongis calloso-apiculatis granulis albidis punctatis 5—7 pol- 
lices longis, racemis erectis pollicaribus ovoideo-subglobosis pedicellis 
flore duplo longioribus, staminibus stylisque 8.—In ditione Pekinensi 
reperit Dr. S. W. Williams, Augusto 1865. (Exsice. n. 12648.) 
Possibly too close to the Japanese P. Kempferi, A. Gray; which, 
however, from a specimen in my possession, seems to differ by its 
oval leaves and linear-lanceolate racemes 25-6 inches in length. Dr.
