either for a polyandrous or a monadelphous 

 flower, as well as for an assemblage of 

 monanclrous ones. Najas is a good and 

 immutable example of this Order. Of 

 Thunberg's Phelypaa I have not materials 

 to form a judgment. 



2. Diandria. The wonderful Valisneria, 

 already described p. 335, is a decisive ex- 

 ample of this. Cecropia also seems un- 

 exceptionable. Of Salix, see Engl. Bot. 

 v. 20 and 21, &c, I have already spoken, 

 p. 47 1 . The scales of its barren and fertile 

 catkins are alike ; its nectaries various. 



3. Triandria. Elegia and Restio, hard 

 rushy plants chiefly of the Cape of Good 

 Hope and New Holland, appear to be 

 without any difference in the accessory 

 parts of their flowers, which is certainly the 

 case with Empetrum, Engl. Bot. t. 526, 

 Ruscus, t. 560, brought hither from Dioe- 

 cia Syngeneda, Osi/ris, Excxcaria and 

 Maba ; Caturus only seeming differently 

 constructed in this particular; but I have 

 not been able to examine the three last.
