Louis Van Houtte. There are three bearing this name; one by Delache, 1854, even, bright, violaceous red; one by Parmentier, 1850, soft pink, deeper center. The one generally grown is probably from Calot, 1867. Rich color, glaring purplish pink. Very satisfactory.

Mr. W. C. Barry... presented the following report:
On Tree and Herbaceous Pæonies.
Louis Van Houtte—is one of the dark crimson sorts, which produce a marked contrast among the fancy colored varieties.
And another, the Louis Van Houtte, (Calot's introduction)—bright purplish cherry color—is a charming sort.
