Mr. V. Burgevin writes: "I regret your editorial comment on the Spiraea venusta. Although the great extent of your botanical knowledge is sufficiently and generally recognized an error is not impossible to you, which may create doubtful opinions of the true nature of plants and a thought that I might be misled by enthusiastic love of horticulture, may find room in the mind of the public. The S. venusta made its first appearance in the catalogue of the most extensive nurseries of James Booth in Hamburg, (Germany,) in the third decade of this century and is described particularly as Spiraea venusta, altogether different from Spiraea lobata, by Dr. F. N. Bosse, ' Vollstaendiger Handbuch der Blum-engaertnerei,' Hanover, 1842. This book com prises three volumes, and has been beyond doubt, one of the best books on horticulture in Germany; and it is, as any other proof you may desire, at your service. I am well acquainted with the S. lobata and have grown it ever since I can recollect, in my garden. Its roots sucker and it is easily cultivated; one root planted in rich soil will soon spread over 2 to 3 feet space and is beautiful when it blooms.

The root of S. venusta is a solid one similar to the Erythrina. I can not account for its scarcity except from the lack of the art of propagation in former years; for this reason it may never have found the way to this or any country. Catalogues have but a small circulation, and therefore this as well as possibly other plants, remained strangers to many intelligent florists. Their foliage as you will perceive by the samples sent are quite different. The S. venusta I have and is now growing strong and healthy and answers all the characters of the genuine article-The form of the flower of the S. venusta is like the S. Lindleyana and is a deeper pink than the S. lobata. Next year when it is in bloom, if you and I are spared, I intend to satisfy you even if I have to bring a flower of it all the way to Germantown.

[We are very much obliged to Mr. Burgevin for this account. We never knew before where the name of Spiraea venusta originated, nor do we now know where is its native country. The class to which it is related should be American or Japan; but it is not referred to in Franchet and Savatier's recent list of the flora of the latter country, nor in Mr. Watson's Index of North American plants even as a synonym.

Mr. Charles Downing sent the Editor many years ago Spiraea venusta, insisting also that it was distinct from S. lobata, but when it flowered no botanical distinction could be discovered. The exact differences are now forgotten but the recollection seems to be that the petals and stamens were larger and brighter, rendering the venusta more showy for cultivation. - Ed. G. M].

Mr. Momme, Wallingford, Pa., writes: "Permit me to say that Spiraea venusta is not a distinct species, but a garden-sport of Spiraea lobata.

The difference is as you say in the petals and stamens, the color of which is of a light rose in the Spiraea lobata, and of a purple rose in the Spiraea venusta, and the latter is of a stronger habit. Mr. Burgevin will find a description in Vilmorin's "Illustrirte Blumen-Gaertnerei," by Dr. J. Groenlaud and Th. Ruempler, Secretary-General of the Horticultural Society of Erfurt; published at Berlin, 1873; Vol. I., page 1159, No. 3, Spiraea lobata var. venusta Hortsmun.
