St. Petersb. vol. ix. (1876), p. 589); and judging from 
the published figures, I should think he is right. If there 
is a second species, it is probably C. Davidiana, as to 
which being different the reader may judge by comparing 
the present plate with 4269, and I may add that the habit 
of the two in the garden is not the same. Then again with 
regard to var. Hookeri, the figure of it given by Decaisne 
precisely accords with that given as the typical tubulosa ;— 
if the names were transposed, no one could tell the differ- 
ence. In the text they are separated by the stems being 
herbaceous and annual in the latter, and woody at the base 
in the former; to which he adds that Hookeri is the most 
precocious of the group, flowering (in Paris, I presume) at 
the end of February (at Kew in September !). Lastly, there 
is a C. azurea, Lindl., stated to be from the Crimea (the 
Tauride), of which Decaisne says that it probably is 
C. Hookeriana (tubulosa, Botanican Macazive), adding that 
the Tauride is given in the Botanica, Macazine as the 
native country of its tubulosa. This is a curious oversight, 
for in that work North China is given as the habitat, and 
there is no allusion to the Crimea. 
There is another branch of this group of the tubulose 
Clematises which inhabits China and Japan, and of which 
C. stans, Sieb. and Zucc., is the type; these have smaller 
more crowded flowers of an opaline colour rather than 
lilac, and usually more acuminate sepals. C. stans has 
flowered at Kew, and will shortly be figured; by which 
time I hope that the genus will have been revised by 
Messrs. Forbes and Hemsley for a census of the plants of 
China which is in preparation at Kew. 
The specimen here figured is from an authentically named 
plant of C. Hookeri sent to Kew by my late friend M. 
Lavallée; it flowered in the open air in the end of 
September.—J. D. H.
