N/^S OF NEW WORLD CYPRESSES (CUPRESSUS) ELBERT L. LITTLE/ JR. Under a conservative intexT)retation, 8 species of cypress, genus Cupressus L. (family Cupressaceae or Pinaceae) , are native in the New World. Three can be divided further into a total of 10 varieties to make I5 distinguishable taxa, which have been regarded also under a narrow concept as 15 species. In this summary of the classification and nomenclature, 2 new combina-tions are made. Also, a few notes including range extensions have been compiled and added here. In the New World the genus Cupressus L. (cypress) is native from southwestern Oregon and California to the Chisos Mountains of Trans-Pecos Texas and south through Mexico to Honduras. As interpreted here, the United States has 7 native species, all represented in California. Oregon, Arizona, New Mexico, and Texas have 1 species each. Mexico has 3 species, of which 2 are also in the United States and the third extends southward in mountains to Guatemala and Honduras. The ancient coniferous genus Cupressus L. (cypress) is repre-sented now by many disjunct, scattered or isolated, apparently relic populations, few enough to be counted. Among these groves morphological differences of varying degrees have been recorded. Many names, mostly at rank of species and variety, have been proposed. A re-evalution of the nomenclature is needed for forthcoming Forest Service studies, including "Atlas of United •States Trees, Volume 1, Conifers and Important Hardwoods" now in press and the revision of "Woody-plant Seed Manual" (Forest Service, U. S. Dep. Agr. Misc. Pub. 63h, kl6 p., illus . 1948). A comprehensive aonograph, based on detailed studies of both wild and cultivated plants, was prepared by Carl. B. Wolf (Taxonomic and distributional studies of the New World cypress. Aliso 1: 1-250, illus. 1948; Horticultural studies and exper-iments on the New World cypresses. Aliso 1: 325-444, illus. 1948) . Few native tree genera in the United States have been studied as intensively in the field and garden. Full field notes were published. Herbarium specimens cited were mostly those relating to nomenclature, including types, and collections by the author. Though specimens were annotated, those in a few large herbaria apparently were not examined. The problem of specific concepts in Cupresses was discussed by Wolf (1948, p. 4-5, IT). He quoted Willis Linn Jepson (Man. Fl. PI. Calif. 57. 1923): "The species depend for their U29
