Rhyncholepis Nuttall. Recent European workers (e.g., J. Holub 1998) have included sect. Rhyncholepis in Bombycilaena, leaving M. supinus Linnaeus in a monotypic genus. Based on phylogenetic data (J. D. Morefield 1992), that approach would include in Bombycilaena species ancestral to, and derived from ancestors of, Micropus. I maintain Micropus in its traditional sense here. Micropus and Psilocarphus appear to be monophyletic sister genera derived from near or within Stylocline. A malformed specimen from Monterey County, California, appears to be a sterile hybrid between M. californicus and a species of Psilocarphus.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Pistillate paleae 8–12 in 2 series, bodies mainly chartaceous, cartilaginous medially, wings prominent, subapical, inflexed, plane to concave; cypselae: corolla scars in distal 1/4; receptacle heights 1.2–1.8 times diams.; staminate paleae mostly 1–3; staminate corolla lobes 4 (–5); staminate pappi of 1–5 bristles |[[Micropus amphibolus|Micropus amphibolus]] |-id=key-0-1 |1 |Pistillate paleae 4–7(–8) in 1 series, bodies cartilaginous to bony throughout, wings obscure, lateral, ± erect, involute; cypselae: corolla scars ± median; receptacle heights 0.5–0.8 times diams.; staminate paleae 0; staminate corolla lobes usually 5; staminate pappi 0 or of 1 bristle |[[Micropus californicus|Micropus californicus]] |} </div></div><!-- -->{{#Taxon: name=Micropus |author=James D.
