Does Fitzroya or Bletilla have more species?
Bletilla Bletilla, common name urn orchid, is a temperate, terrestrial genus of orchids containing five currently recognized species distributed through China, Japan, Taiwan, south to Vietnam, Thailand and Myanmar. The name is actually a diminutive of "Bletia" because of the resemblance between the two genera even though Bletia is a New World genus. The genera Jimensia and Polytoma are generally included into "Bletilla". This genus is abbreviated Ble in trade journals.
Bowenia The genus Bowenia includes two living and two fossil species of cycads in the family Stangeriaceae, sometimes placed in their own family Boweniaceae. They are entirely restricted to Australia. The two living species occur in Queensland. "B. spectabilis" grows in warm, wet, tropical rainforests, on protected slopes and near streams, primarily in the lowlands of the Wet Tropics Bioregion. However it has a local form with serrate pinna margins that grows in rainforest, "Acacia"-dominated transition forest and also "Casuarina"-dominated sclerophyll forest on the Atherton Tableland, where it is subject to periodic bushfire. "B. serrulata" grows in sclerophyll forest and transition forest close to the Tropic of Capricorn.
