plants that differ from our shrubby tall material. However, the type area is presently covered with water from a dam on the Missouri River, and it is not possible to exclude the possibility of A. canescens as it has been interpreted for the past century to have existed at that site during the Lewis and Clark Expedition, if that is indeed where the lectotype was collected.”
F. Wire Lettuce (aka Few-
Flowered Wire Lettuce and
Prairie Skeletonplant),
Stephanomeria pauciflora,
is found along the
southern part of this loop
walk. The range of this
genus is confined to the
western United States and northern Mexico. This particular species is found in Sonora and Chihuahua in addition to the range shown on the BONAP map above. Skeletonweed, which it may be confused with, is a noxious plant and is in a different genus. This species may hybridize with S. tenuifolia. Like many plants in our desert borderlands, this one has few leaves. (Photograph from May 20, to the right.)
G. Many species of grass are growing at the mid-point of this walk, where a wooden walkway (photograph from August 18 at the top of following page) crosses the main “waterway” of the ciénaga. (Photograph from May 20, by Mike Barnes, at the middle of the following page.)
