XVI APPENDIX. 



A few Fabaceous genera seem confined to the Colony. 

 Of these the curious Isotropis striata, Benth. is a little pros- 

 trate bush, with its sterile branches so different from those 

 which bear flowers that one would never suppose them 1o 

 belong to the same species. Roea and Dichosema are two 

 others of little beauty, to which have to be added Orthotropis"' 

 and PtychosemdJ^ of Mr. Bentham's herbarium, neither of 

 which possess the slightest interest for horticultural purposes ; 

 and Cyclogyne,^'^ which is quite a new form for Australia, 

 and calls to mind the European species of Onohrychis ;
