Stylocline intertexta

Stylocline intertexta is a species of flowering plant in the family Asteraceae known by the common names Morefield's neststraw [1] and Mojave neststraw. It is native to the Mojave and Sonoran Deserts of California, Nevada, Utah, and Arizona, where it grows in rocky, sandy desert soils. It likely evolved as a hybrid between woollyhead neststraw (Stylocline micropoides) and baretwig neststraw (S. psilocarphoides); it is a mix of their morphological traits and it occurs alongside both of them. [2] It reproduces itself, producing fertile offspring, and it meets other criteria for any other definition of a species, so it was described to science as such in 1992. [3] It is a small annual herb growing at ground level and reaching just a few centimeters in length. It is usually coated in white hairs, often woolly. The small, pointed leaves are oval to lance-shaped and measure up to 1.5 centimeters long. The inflorescence bears spherical flower heads each a few millimeters in diameter. The head has no phyllaries, just a ball of tiny woolly white flowers.
