April 6th, 1819. This day were received specimens of 

 the Casuarina, described in a former Volume of the Transac- 

 tions of the Society,* as growing in the gardens of His Royal 

 Highness the Grand Duke of Saxe Weimar, at Belvedere ; 

 they had been transmitted to the Society, from Weimar, by 

 Dr. Noehden, conformably to the orders of His Royal 

 Highness. The plant in question seems to be the male of 

 a dioecious species, which was found growing on the south 

 coast of New Holland, by Mr. Brown, and by him called 

 Casuarina acida, on account of the flavour of its ultimate 

 raaiuli, which flavour even the dried specimens in some de- 

 gree preserve, as does also the specimen received from 

 Weimar. Labillardiere, in his Plants of New Holland,f 

 has described and figured as Casuarina quadrivalvis, a native 

 of Van Diemen's Land, which has a strong resemblance to 

 this plant, and is perhaps the same ; but should it prove so, 

 the specific name of quadrivalvis, derived from the number of 

 the valves of the calyx of the male flower, is objectionable, 

 inasmuch as all the species of Casuarina that have yet been 

 examined have, according to Mr. Brown's observations, 

 that structure. The Casuarina equisetifolia is a more tender 

 plant than that under consideration; it is a native of the 

 warmer parts of New Holland, as well as of the South Sea 

 Islands, and is readily distinguished from the C. acida by its 

 pendulous pubescent branches, and by being monoecious.
