DEVELOPMENT AND DISTRIBUTION OF LEGUMINOS&. 375 
Gastrolobium, Burtonia, Sphcerolobium, Gompholobium, 
Goodia, Oxylobium, Pultenzea, Dillwynia, Hutaxia, Aotus, 
Phyllota, Daviesia, Mirbelia, Latrobea, Hovea, Templetonia, 
Bossizea, Platylobium, Kennedya, Hardenbergia, Penta- 
dynamis, Lamprolobium, Podopetalum, Castanospermum, 
Barklya, Petalostyles, and Labichea in Australia, appear to 
have developed in these countries respectively, and never 
to have migrated therefrom. 
In the second place there are others, such as Clianthus 
and Swainsona, which are practically confined to New 
Zealand and Australia, and these may be considered as 
strictly indigenous in each of the two countries, inasmuch 
as the species are endemic in each country considered. 
Swainsona, however, has many close relations in other 
continents and lands, for example: Lessertia in Africa, 
Colutea and Astragalus in the Northern Hemisphere, and 
another genusin the Malay Archipelago. The significance 
of this will be considered later. 
In the third place, genera in Australia, such as Crotalaria, 
Trigonella, Lotus, Psoralea, Indigofera, Tephrosia, Millettia, 
Sesbania, Desmodium, Glycyrrhiza, Glycine, Hrythrina, 
Galactia, Vigna, Atylosia, Flemingia, Dalbergia, Derris, 
Sophora, Mezoneurum, Cassia, Bauhinia, Erythrophlocum, 
Adenanthera, Neptunia, Acacia, Albizzia, Pithecolobium, 
and Archidendron, are strictly indigenous, because these 
types, although common to the tropics and sub-tropics 
generally, and possessing some species in Australia, which 
are common to other countries, nevertheless possess 
endemic species in that country. <A few of these genera, 
however, such as Vigna, Derris, Trigonella, and Sesbania, 
are doubtful. A significant fact is the absence of these 
genera from New Zealand. 
There remain the genera EKdwardsia and Canavalia in 
New Zealand, and the genera Ormocarpum, Aischynomene,
