Which genus has more species, Burretiokentia or Iris?
Burretiokentia Burretiokentia is a genus of palms (Arecaceae) endemic to New Caledonia containing five species. The relationships between Burretiokentia and some other genera of the tribe Basseliniinae including "Physokentia" and the New Caledonia endemic "Cyphophoenix" are not clear.
Iris arenaria Iris arenaria (sand iris) is a species in the genus "Iris"; it is also in the subgenus of Iris and in the "Psammiris" section. It is a rhizomatous perennial, from Central Europe, found in Hungary, Austria, Romania, Czech Republic and Ukraine. It has grass-like leaves, a short stem and pale yellow flowers. It has had a mixed origin and was once "Iris humilis subsp. arenaria", a subspecies of "Iris humilis" (another Psammiris iris), until it was reclassified as a separate species. But many sources still state that it is either a synonym or subspecies of "Iris humilis". It is cultivated as an ornamental plant in temperate regions.
