Iris virginica L. (Carolus Linnaeus, 1753)
Curtis's Botanical Magazine
SEPARATING VERSICOLOR FROM VIRGINICAR. C. Foster 1937 accepted Waller's subsection Virginicae which included Iris versicolor and Iris virginica. He offers the following note "To differentiate between the two species comprising this subsection can be extremely difficult, if not impossible, in poorly preserved herbarium material. That there are actually two species, instead of one as assumed by Dykes, has been clearly shown by Anderson. By a lengthy series of diagrams showing the proportions of floral parts to each other, he established the fact that there are certain differences, the petals of Iris versicolor being lanceolate, short, narrow in proportion to the sepals, and oblanceolate to spatulate. Spathe, stem, and pedicel differences also are useful in separating the two. Nevertheless, despite Anderson's insistence that the outer spathe-valves of I. versicolor never become foliaceous, while those of I. virginica frequently do, one of the first specimens of the former seen by me in the Gray Herbarium, J. C. Parlin from North Berwick, Maine, has a foliaceous outer spathe. The frequency with which this occurs, however, is much less than is true of I. virginica. It is in the seeds of the two species that an almost infallible means of separation is found. I. virginica has seeds with a dull corky covering, like a smaller edition of seeds of the Hexagonae. I. versicolor has seeds with a thinner, shiny, hard covering, resembling those of I. setosa var. canadensis. The seeds and frequent foliaceous spathes of I. virginica strongly suggest a relationship with the Hexagonae. At the same time, when the spathes are not foliaceous, there is a marked similarity in size, shape, and even coloring to those of I. tridentata." Three varieties are listed below, but one, var. carolina, has not been formerly described although Viosca 1935 first suggested that three are warranted, R. C. Foster 1937 agrees.
