Japanese Peonies
Including direct importations from Japan, and Kelway's "Imperial" and Hollis' New Seedling Japanese Peonies
A new race of Peonies of a distinct type, forming a separate class, intermediate between the single and the double types, and distinguished by their stamens being transformed into narrow petaloids. [...]
I have retained the Japanese names, with their translation, prefixed by the Amreicannames, which were given to this set by the Peony Society of the American Florists.

Rare Single Japanese Peonies
The so-called Japanese Peonies are those which have one or two rows of petals and centers of stamens much thickened. These are almost devoid of pollen and oftentimes make a thick cushion of golden yellow. The effect is very beautiful and distinct and they continue to bloom throughout the Peony season. Although strong growers they propagate slowly and the stocks are usually limited.
