Other claims from this paper (15)
- Observation Caladenia contains 376 species and subspecies.
- Observation Almost all Caladenia species are endemic to temperate and southern semiarid Australia.
- Observation Eleven Caladenia species occur in New Zealand, 10 of them endemic.
- Observation One Caladenia species is widely distributed in eastern Australia and the western Pacific.
- Observation Only three Caladenia species occur in both south-western and south-eastern Australia.
- Observation Subgenus Drakonorchis is endemic to the South-west Australian Floristic Region.
- Observation Subgenera Calonema, Phlebochilus and Elevatae occur on both sides of the Nullarbor Plain.
- Observation Subgenus Caladenia is primarily eastern Australian but also extends to the western Pacific.
- Observation The largest subgenera, Calonema and Phlebochilus, have radiated extensively.
- Observation Calonema has a greater concentration of species than Phlebochilus in the more mesic parts of the SWAFR.
- Observation Within the SWAFR, the major biogeographic division within Caladenia follows the 600-mm isohyet.
- Association Biogeographic districts for Caladenia correlate with a combination of underlying geology and surface soils.
- Observation Areas of high endemism contain diverse edaphic environments.
- Mechanism Climatic and edaphic requirements are likely key drivers of rarity in Caladenia.
- Mechanism Climatic and edaphic parameters may act in concert with mycorrhizal and pollinator specificity in driving rarity.
