View Abstract
The suggestion is made by Hitchcock (in Hitchcock et al., 1969: 106) that the 7 Jul 1806 Lewis collection is "probably the actual type" of var. depressa. He declares this even though Pursh states he saw the taxon "in New York, and particularly in the province of Maine, in rocky or gravelly situations." Nowhere does Pursh mention Lewis and Clark specimens. However, he did have access, in London, to a Lewis and Clark specimen (LC-PH 114), and he did ascribe a varietal name ("nana") to the collection. The use of the name appears to be based on the European species Juniperus nana Willd. (Sp. Pl. 4: 854. 1806). Pursh did not formally propose the new combination. Ewan (1979: 82) seems to support Hitchcock's notion, noting that Pursh likely did not collect specimens while in Maine in 1811. Nonetheless, there is authentic material from eastern New York gathered by Pursh that belongs to var. depressa (McVaugh, 1935: 30), and we here typify the name with that material.
The variety was first found by Lewis on 17 Oct 1804 (Lewis 47, PH-LC 111, PH-LC 112) below the mouth of the Cannon Ball River in Sioux Co., North Dakota (Moulton, 1987a: 471). Either Lewis or Clark could have gathered the 7 Jul 1806 specimens (PH-LC 113 and PH-LC 114). Lewis was near Lewis and Clark Pass, Lewis and Clark Co., Montana (Moulton, 1993: 95-96); Clark and his party crossed the Continental Divided via Gibbons Pass on the Ravalli-Beaverhead Co. line (Moulton, 1993: 169-171). The plant occurs in both areas. Neither explorer mentions the plant.
