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.
Labyrinthodontia Labyrinthodontia (Greek, "maze-toothed") is an extinct amphibian subclass, which constituted some of the dominant animals of late Paleozoic and early Mesozoic eras (about 390 to 150 million years ago). The group evolved from lobe-finned fishes in the Devonian and is ancestral to all extant landliving vertebrates. As such it constitutes an evolutionary grade (a paraphyletic group) rather than a natural group (clade). The name describes the pattern of infolding of the dentin and enamel of the teeth, which are often the only part of the creatures that fossilize. They are also distinguished by a heavily armoured skull roof (hence the older name "Stegocephalia"), and complex vertebrae, the structure of which is useful in older classifications of the group.
