Actaea Cimicifuga simplex DC. Prodr. 1: 64. 1824. 
Cimicifuga simplex Wormsk.; Turcz. Bull. Soc. Nat. Mose. 15: 87, 1842. 
A perennial herb, two to four feet high, with spreading compound 
leaves and racemes of white flowers on long slender stalks. The 
There are from twenty-five to forty flowers to a raceme, each on a 
short pedicel. ‘The deciduous, pink-tinged sepals are usually two 
in number, larger than the numerous white, notched petals. The 
numerous white stamens are more conspicuous than the other 
floral parts, and in the center of the flower are two or three carpels 
which mature to form nearly glabrous, many-seeded follicles on 
long stipes. 
Cimicifuga simplex was probably first found between 1830 and 
1835. It is native of Japan, China, Dahuria and other parts of 
eastern Asia. ‘There are specimens in the herbarium of the New 
York Botanical Garden collected by Maximowicz in Japan in 1862, 
and by Augustine Henry in China. 
This plant has been cultivated for some time, often as Pityro- 
sperma acerinum, Cimicifuga acerina, or C. japonica, but it is not 
that species. It is a strong-growing perennial, thriving in full sun 
or partial shade. ‘The foliage is attractive during the summer, 
and the graceful spikes of flowers come in September and October. 
It is propagated by division of the root in fall or spring.
