74 DR. H. F. HANCE ON NORTH-CHINA PLANTS. 
1. The leaves of both so-called species vary very much in size. 
2. The same as to shape. 
3. Both are apt to be thick (probably, when fresh, somewhat 
succulent ?). i 
4. C. Murrayi is at times glabrous even when young. 
5. The peduncles of both appear to be articulated; and 
6. The anthers of C. Murrayi also seem to be purple. 
7. There is not material to settle the question of number of 
placentas ; but C. Murrayi is not restricted to four. 
Finally, I conceive that Dr. Anderson might perhaps well 
have gone further, and clubbed these with C. spinosa, L., as 
varieties at most.—L. F. Stewart, M.D.]

Tue following brief notes were drawn up when examining and 
laying in the herbarium various plants selected from small col- 
lections made, for the most part, in the neighbourhood of Peking, 
by Dr. Emil Bretschneider, Physician to the Imperial Russian 
Legation, Dr. Wells Williams and the late Mr. Richard Conolly, 
respectively Secretaries to the United States and our own Lega- 
tions in that capital, and especially the Rev. Father Armand David, 
priest of the * Congrégation des Missions Etrangéres," a most 
zealous naturalist, to whose courtesy I am indebted for many 
rare and interesting species, some of the novelties amongst 
which I have already been privileged to dedicate to their ac- 
complished discoverer. These notes mainly refer either to species 
apparently new to science, to such as are so imperfectly known 
that any additional information regarding them may be assumed to 
be useful, or to others not previously enumerated, either in the 
‘Index Flore Pekinensis’ of M. Maximowiez (a catalogue the 
materials for which must have been amassed under great diffi- 
culties, but which is nevertheless remarkable for its accuracy and 
completeness) or in the botanical section of Radde’s ‘ Reisen in 
Ost-Sibirien’ (where Dr. Regel bas described several interest-
