Abstract: | Evolvulus alsinoides and E. arizonicus have historically been difficult to distinguish. Most specimens of these two taxa may be identified by corolla size; all specimens in this region by sepal size. Typification of E. arizonicus is discussed, and a lectotype chosen. The name Ipomoea hirsutula has been a mixed concept applied to two species in publications for a number of years. Proper names of these species (Ipomoea hederacea and I. purpurea), their traits, and ways of distinguishing them are discussed. |
