A Preliminary List of the Vascular Plants
of the Davis Mountains, Jeff Davis County, Texas
September 2005 Draft
William R. Carr, Botanist
The Nature Conservancy of Texas
This compilation includes plant taxa previously reported from the Davis Mountains in various published and unpublished materials. Principal sources include: 1) a dissertation on the vegetation of the Mount Livermore area by L. C. Hinckley (1940) as later emended by S. Sikes and J. Smith (1975); 2) a list of the plants of Davis Mountains State Park compiled over many years by B. H. Warnock (1967) and later emended by biologists with the Texas Parks and Wildlife Department (1992); 3) a thesis on the flora and vegetation of the Forbidden Mountain area (Larke, 1989); and 4) a vegetational survey of Lower Madera Canyon and the Timber Mountain area (Weedin, undated). Sources of additional taxa include: 5) Hinckley, 1944; 6) Palmer, 1929, cited sparingly due to nomenclatural uncertainty; 7) files of the Texas Natural Heritage Program; 8) Powell, 1988; 9) Powell, 1994; 10) Warnock, 1977; 11) Warnock, 1974; 12) Carr, 1997a and/or Carr, 1997b; 13) Zech et al., 1997; 14) specimens collected by R. D. Worthington (Worthington, 1999); 15) miscellaneous specimens at Sul Ross State University (transcription remains very incomplete!); 16) observations by John Karges, 1997-present; 17) observations of Linda Hedges, 1997-present; 18) additions to previous lists as reported by Bartel (2002); 19) Powell & Weedin, 2004. The coarse filter provided by these sources undoubtedly failed to capture many-- perhaps hundreds-- of the plant taxa of the region; the secondary sources all cover a larger area and generally don't mention specific Davis Mountains occurrences of common or widespread taxa. But if nothing else this list should serve as a starting point for those with little knowledge of the local flora.
Nomenclature follows various sources (Benson, 1982; Flora of North America Editorial Committee, 1993; Gould, 1975; Hatch, Gandhi and Brown, 1990; Johnston, 1990; Powell, 1988; Powell, 1994; and others), but in general either the accepted name or a synonym can be traced to the Manual of the Vascular Plants of Texas (Correll and Johnston, 1970). Common names follow Hatch, Gandhi and Brown (1990) or Warnock (1970, 1974, 1977).
