CHINA.

Flowered with Messrs. Paul & Son, The Old Nurseries, Cheshunt, in June, 1912. In its strongly setose character the species recalls R. acicularis, Lindl., but it differs from this and every other member of the Cinnamomeae in its lax, many-flowered panicles, which give the plant a very graceful appearance. The flowers are also rather small, and the sepals relatively long, being about twice as long as the petals. Messrs. Paul received this rose from Messrs. Vilmorin, Paris, and from a dried specimen afterwards received from the latter firm it appears that they obtained it from China some years ago with the seed number 711, and that it flowered with them in June, 1903. It has recently been received from Mr. M. Nicholls, Sevenoaks, with the number, Wilson, 4418, showing that it has since been collected by Mr. E. H. Wilson during his recent mission to China.
