Discussion | Meximalva filipes is very reminiscent of the widespread Sidastrum paniculatum, differing from that primarily by its solitary, axillary flowers each subtended by a reduced leaf and its non-reflexed petals. In the flora area, it is known from scattered areas of central, southern, and southwestern Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
