Distribution by biogeographical region
The locality where the specimen was found naturally and excludes cultivated specimens. Distribution can be very valuable in identifying specimens, but should be treated cautiously, as our knowledge of taxon distributional ranges is generally limited. Many distributions could be extended as sampling increases. Users should seek additional correlating characters when an identification is ultimately based on distribution.
DISTRIBUTION BY BIOGEOGRAPHICAL REGION areas that are important centres of diversity within the flora. For example, Tephrosia is almost entirely tropical in distribution, Swainsona is best developed in the arid and semi arid inland, Gastrolobium in Western Australia"s south west and Pultenaea in the temperate south-east. Broadly, these regions reflect species eco-physiological tolerances, and historical processes of isolation and diversification. Consequently, this level of distribution has some biological reality and is likely to be the most reliable.
