Chaetadelpha Wheeleri
''Chaetadelpha'' is a genus of plants in the family Asteraceae containing the single species ''Chaetadelpha wheeleri'', or Wheeler's skeletonweed. This brushy perennial plant is native to the western United States (Nevada, eastern California, southeastern Oregon). ''Chaetadelpha wheeleri'' forms a low bush with plentiful erect stems covered in very narrow, long and pointed leaves. Branchlets emerge from the stems and each bears a cylindrical flower which opens at the end into a star-shaped white or pale purple flower with five ray florets. The center of each head is filled with curly pollen-dusted anthers The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filam .... This species is found most often in sand and scrub, particularly in desert regions. References External links USDA Plant ...

Chondrilla Juncea
''Chondrilla juncea'' is a species of flowering plant in the family Asteraceae known by a number of common names, including rush skeletonweed, gum succory, devil's grass, and nakedweed. The plant is native to Europe, Asia, and North Africa, but it is known throughout most temperate regions of the world as an introduced species which is usually considered a noxious weed. Description It is a thin, spindly plant which reaches a meter in height. It starts from a basal rosette of leaves and branches extensively, often forming a weedy thicket. It produces small dandelionlike flowers with rectangular yellow ray florets. The fruit is an achene about a centimeter long topped with a white pappus. It reproduces by seed but also by cloning itself at the root; tilling of soil and chopping up plants actually help this species disperse by sectioning and distributing root parts. Distribution Native From the Aral Sea area in Kazakhstan and Uzbekistan in Central Asia, westward through Russia, th ...

Eriogonum Deflexum
''Eriogonum deflexum'' is a species of wild buckwheat known by the common names flatcrown buckwheat, flat-top buckwheat, and skeletonweed. This plant is native to the southwestern United States and northwestern Mexico, where it is common and grows in a variety of habitats, especially desert scrub Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this .... It is somewhat weedy where it is most abundant. This is an annual which varies in size from small patches on the ground to tangled bushes approaching two meters in height; it may be dense or thin and spindly. This is a brown or greenish weedy-looking herb with a many-branched stem. The leaves are located at the base of the plant and are rounded and woolly and one to four centimeters long.

Pleiacanthus Spinosus
''Pleiacanthus'' is a monotypic genusLee, J., et al. (2002)Phylogeny of ''Stephanomeria'' and related genera (Compositae–Lactuceae) based on analysis of 18S–26S nuclear rDNA ITS and ETS sequences.''Am J Bot'' 89 160-8. of flowering plants in the family Asteraceae containing the single species ''Pleiacanthus spinosus'' (formerly ''Stephanomeria spinosa''), which is known by the common name thorn skeletonweed, or thorny skeletonweed. It is native to the western United States from Montana and Idaho to southern California and Arizona, where it grows in many types of mostly dry habitat from deserts to mountains. It is a spindly subshrub producing several slender stems up to 40 or 50 centimeters tall from a woody caudex. The stems divide many times into short, rigid branches which narrow to sharp thorn-tips. The plant is mostly hairless except for brownish woolly tufts at the base and below the basal leaves. The leaves are small and linear on the lower stem, and reduced to scale-like ...
