coll. Dr. S. W. Williams. 
I mention this to confirm Maximowicz’s suspicion of its being 
Bunge's Arum macrourum. The Chinese specimens are identical 
with Japanese. 
48. PoLYGONATUM CHINENSE, Kth. 
Dr. Bretschneider, who has sent me a very good specimen of 
this from Peking, informs me that it is there cultivated as a me- 
dicinal plant. Kunth distinguishes this from the Nipalese P. cir- 
rifolium, Royle, by its leaves being in fours not opposite ternate 
or senate, by its two-, not three-flowered peduncles, and its pa- 
pillose filaments. But I find the leaves, with the exception of 
the two or three upper whorls, constantly in fives, the peduncles 
one- to four-, but generally three-flowered, and the filaments quite 
smooth, though looking sometimes papillose from the pollen-grains 
which have fallen from the anther-cells upon them. The species 
of Polygonatum, indeed, vary a good deal. Thus a specimen of 
P. officinale in my herbarium, from the Picentine Apennines, has 
the leaves 1? inch and flowers less than 4 inch long, whilst a 
plant of the same species gathered by the late Mr. Conolly, our 
Secretary of Legation at Peking, at Nikolajewsk, on the Amur, 
has leaves 64 inches and flowers 14 inch long; and I have a Peking 
specimen in which one of the axils bears a four-flowered raceme! 
Hence, though I do not know the Indian plant, it appears per- 
missible to doubt the distinctness of the Chinese one. 
49. MonocHorIa Korsakow1t, Rgl. $ Maack.—In fossis circa Peking, 
Sept. 1866, coll. Dr. S. W. Williams. 
Recorded hitherto only from Lake. Kengka, in the Ussuri ter- 
ritory ; but it is doubtless the plant mentioned in Maximowicz’s 
* Index Flor: Pekinensis’ as a questionable variety of M. vaginalis, 
Pr. The species appears quite distinct ; and my specimens agree 
well with both Regel’s diagnosis and figure (Cent. Fl. Ussur. t. 12. 
ff. 1-7). 
50. Cyperus Monni, L. fil.—In fossis agri Pekinensis, Octobri 1860, 
legit R. Swinhoe. 
Found in Manchuria along the Ussuri, but not before recorded 
from China. The lower portion of the stem and the leaves are 
wanting ; but the glumes, achene, and bifid style are quite the same 
as those of a Tyrolese specimen. I had carelessly, in the * Adver- 
saria, referred this to C. procerus, Roth, which is, indeed, so e*-
