dica,” C. tubulosa would, from its inflorescence, fall rather into 
Cheiropsis ; but its affinities are against such a collocation. 
2. NASTURTIUM GLOBOSUM, Turcz.?—In paludosis, Pagoda Hill, 
juxta Peking, m. Augusto, 1867, legit Dr. S. W. Williams. 
The Peking plant, which I have little doubt is referable to the 
above species, is certainly identical with the South-Chinese one 
described by me (Seem. Journ. Bot. iii. 378) under the name of 
N. eantoniense. Ledebour places it in the genus Cochlearia, 
though its nearest affinity is incontestably with the North Ameri- 
can JN. hispidum, DC. ; whilst Turezaninow (Flor. Baic.-Dahur. i. 
109) remarks on its relationship to Zetrapoma, which Dr. Asa 
Gray once regarded as a monstrosity of N. terrestre, R. Br., an 
exceedingly close relative of the Chinese plant *. In ag eneral 
classification, it would seem very desirable, if possible, to retain 
the genus Roripa for those plants which oscillate between Was- 
turtium and Cochlearia. 
3. DRABA NEMOROSA, L., B. LEIOCARPA, Led.—In agris circa Jehol, 
Maio, R. P. David. 
Found in Japan and Manchuria, but not before, to my know- 
ledge, recorded from China proper. 
4. Linum DAVURICUM, Schult.—E paradiso imperiali aliisque juxta 
Peking locis specimina miserunt Dr. S. W. Williams et Rev. X 
David. 
I think Miquel has rightly identified Planchon's L. stelleroides 
with this. Planchon's diagnosis (Hook. Lond. Journ. Bot. vii. 
178) must have been drawn up from starved specimens; for 1 
find the leaves in well-developed ones as much as 9 lines long 
and a line wide. Miquel describes the inner sepals as without 
glands; but these appendages are variable both in number and 
prominence. Father David notes the petals as being rose- 
coloured and conspicuous. This species has perhaps as much 
claim to be placed under Linastrum, $ Dicrolinum, as under 
Eulinum, § Adenolinum, where Planchon with doubt located it. 
Dr. Williams tells me that L. usitatissimum is grown at Kalgan, 
but only as an oil-seed-yielding plant, not for its fibre.
