Which genus has more species, Cibotium or Crowea?
Cibotium Cibotium (from the Greek "kibootion", meaning chest or box) is a genus of 11 species of tropical tree fern—subject to much confusion and revision—distributed fairly narrowly in Hawaiʻ i (four species, plus a hybrid, collectively known as hāpuʻ u), Southeast Asia (five species), and the cloud forests of Central America and Mexico (two species). Some of the species currently listed in the literature seem to be synonyms or local-variant subspecies. "Cibotium glaucum", from Hawaiʻ i, is the most frequently encountered "Cibotium" species in the horticultural trade, together with its sibling species "Cibotium chamissoi" and the potentially huge "Cibotium menziesii". The remaining Hawaiian "Cibotium", "C. nealiae", is a 1 m dwarf variety, restricted to the island of Kauaʻ i that is never seen in the horticultural trade. Precise identification of "Cibotium" species is difficult, although all have shiny and rather waxy fronds when viewed from above, with varying degrees of powdery-pale blush when seen from underneath. The natural habitat of "Cibotium" is among the dripping trees and stream gullies of the rainforests on Hawaiʻ i's windward volcanic slopes.
