To which taxonomic category do both Maxillaria and Leonotis belong?
Leonotis Leonotis is a genus of flowering plants in the family Lamiaceae. One species, "Leonotis nepetifolia", is native to tropical Africa and southern India. It is naturalized throughout most of the tropics. The other species are endemic to southern + eastern Africa.
Ostreoidea Ostreoidea is a taxonomic superfamily of bivalve marine mollusc, sometimes simply identified as oysters, containing two families. The ostreoids are characterized in part by the presence of a well developed axial rod. Anal flaps are known to exist within the family Ostreidae but not within the more-primitive Gryphaeidae. The scar from the adductor muscle is simple, with a single, central scar. In the majority, the right valve is less convex than the left.
