and parHcIarly numerous in species in S. Africa. The Australian species are all endemic 

 vitithc excepUou of T. purpurea, and, even of that, scarcely anv of the Australian varieties 

 quite agree with the comuion Asiatic auJ Afiicau forms. The Australian species aho all, 

 wi h the exception perhaps of T. /ammea and T. crocea, belong to the section R.inerla, 

 wtti temiiaal or lea.-opposed racemes or axillary clustered pedicels, and to the lar-'e subsec- 

 tioa with subulate or small stipules, except perhaps T. vermhsa, m which thev are broad and 

 s mate, but not so much so as in the S. African Apodipwmenes. Several species difTer from 

 ail extra-Australian ones in the venation of the leaflets. One Australian species also T. 

 irachycarpa ,s remarkable for having the flowers and fruit of the African Reqniemas, 

 vMiUst another, T. cortacea, has very nearly their folia-e. In general the Australian spe- 

 cies more even than the Asiatic ones, are extremely ditricult to define; the terminal or 

 Miliary, racemose or clustered inflorescences, usually so distinct, seem to pass the one into 

 tlie other or to be blended together even on the same specimen, the foliage and indnmen- 

 ram IS more than usually diversified and variable, and wlien to this is added the imperfcc- 

 nou of the specimens we poss-ss from tropical Australia, it must be expected that further
