Additional comments on Linnaean types of eastern North American plants

Abstract

REVEAL, J. L., 1985. Additional comments on Linnaean types of eastern North American plants. Five temperate eastern North American species proposed by Linnaeus in the 1753 edition of Species Plantarum are typified. As a result significant nomenclatural changes occur in two genera, Lechea and Scutellaria. Clitoria mariana, described in 1753, is lectotypified on a specimen examined by Linnaeus {Clayton 108). No nomenclatural change results from this lectotypification. The existing lectotype of Lechea minor is not in accordance with Linnaeus' protologue. The specimen used and cited by Linnaeus was representative of a species currently known as L. intermedia Leggett ex Britton. That name becomes a synonym under L. minor and the entity previously referred to as L. minor must now be called L. thymifolia Michx. Two specimens of Polygonum sagittatum are potential lertotypes. The Kalm specimen is an atypical expression most similar to an endemic restricted to SE Virginia where Kalm never collected. A second collection, a garden specimen in the Clifford herbarium, is representative of the species as found throughout its range. The latter specimen is selected here as the lectotype. Gronovius and Linnaeus mislabelled specimens of Sanicula marilanica and S. canadensis so as to confuse hopelessly the application of the names. By examining the original Clayton specimens and descriptions written by Gronovius, and cited by Linnaeus, it is possible to lectotypify each species on Clayton specimens so as to maintain the modern application of the names. As a result of restricted concepts and existing typification, the name Scutellaria integrijolia must be applied to what is now called S. nervosa Pursh while S. hyssopifolia must now be applied to what has long been known as S. integrijolia. A new combination, S. hyssopifolia var. hispida (Benth.) Reveal, is made.
