It is said to have been abundant, a few years since, near Calumet, 
Ind., from which locality it has been nearly exterminated by 
florists. 
A monstrous flower of this species, found June, 1881, at Pine Station, 
Ind., near the shore of Lake Michigan, had the following charac- 
teristics; it was borne on the same stalk with a flower which had 
the ordinary form of the species. Its organs were arranged in 
five alternating whorls, each of three pieces, save the third, which 
consisted of but two; the floral organs were adnate to the ovary; 
the stamens gynandrous, and the styles united as in the ordinary 
forms; but the ovary was not twisted, the stigmas w 7 ere deeply 
and equally three-lobed, and the leaves of the perianth were 
equally developed, Bastin , in his College Botany.
