Under this name a very pretty red flowered shrub is becoming common in collections, having been introduced from China by Mr. FORTUNE. With us it is too apt to form leaves rather than flowers, but the rich ruby tints of such as do appear resemble clusters of gems set in green foliage; in a hot summer we have no doubt the blossoms would be abundant Such, indeed, would seem to be the case on the continent, if we may trust a figure in the Flort des Serree, where M. Planchon has changed the name to 8. Fortunei. It is there represented as bearing great corymbose panicles of a blood red color, producing a. far more striking effect than anything we have seen in England. M. PLANCHON thinks that this is not the S. callosa of Thunberg, and, therefore, changes its name, and we say very needlessly. His reasoning upon the subject would be admissable, had Thunberg been a botanist upon the exactness of whose descriptions any reliance could be placed; but as he was just the contrary, his plants, where authentic specimens are unattainable, as is the case here, are so many puzzles, to be identified by probability, rather than by what he says or omits to say.
No one, we suppose, can doubt that his plant was some common red flowered Japanese Spiraea; that the present plant undoubtedly is; and it answers to his words as well as plants usually do. M. Planchon has no evidence that the plant was not S. callosa, there is a fair probability that it was; and we cannot perceive the wisdom of perplexing the world with yet another alias, when the only reason assignable for doing so is mere conjecture. In the absence of direct proof, one conjecture is as much entitled to attention as another. But the mania for changing names seems incurable, and we shall now have nurserymen selling Sp. Fortunei as a fine new Japanese shrub to the very persons who already have it growing in their shrubberies under the name of S. callosa. - Gardeners' Chronicle.
