BOTANY OF TEREA AUSTRALIS. 25 



Good Hope, in equinoctial and North Africa, in the different 

 regions of America, in New Zealand, in India, very sparingly 

 in North Asia, and lastly in the South of Europe, where, pss 

 however, only two species have been observed, namely, 

 Anagyris fcetida, and Cercis siliquastrum ; but the latter 

 having a straight embryo and a habit approaching to that 

 of Baahinia, rather belongs to Lomentaceae. 



Among the Diadelphous genera of Terra Australis the 

 most remarkable in habit and structure, namely Platylobium, 

 Bossigea, Hovea, Scottia, and Kennedia, are found chiefly 

 in the principal parallel and higher latitudes ; within the 

 tropic the greater part of these cease to exist, and most of 

 the genera which there occur are common to other coun- 

 tries, especially India. 



ATHEROSPERME^.^ Jussieu, in his excellent me- 

 moir on Monimieae^ has referred Pavonia of Ruiz and 

 Pavon and Atherosperma of Labilardiere to that order, from 

 the other genera of which, namely, Ambora, Monimia, and 

 Ruizia, they appear to me very different, not only in the in- 

 sertion of the seed, the texture of the albumen, and relative 

 size of the embryo, but in having antherse similar to those 

 of Laui-inse. I separate them therefore into a distinct 

 family with the name of AxHEROSPERMEiE. The propriety 

 of this separation is confirmed by the discovery of two New 

 Holland plants, evidently belonging to this family, but 

 which have hermaphrodite flowers ; a structure not hkely 

 to occur in Monimiese, in which what has been termed 

 calyx is more properly an involucrum.
