Account of a Species of Casuarina. 333 



smaller plant promises to grow taller than the other, but is 

 not likely to form a spreading head. As this tree can bear 

 our climate in a building which only protects it from a de- 

 gree of cold below the freezing point, it is probable it will 

 grow well in the open ah* in climates a little more temperate. 



With regard to the botanical character of this Casuarina 

 some doubt has arisen. It does not seem to be the species, 

 usually called Equisetifolia. The Belvedere plant, according 

 to its present appearance, is clearly dioecious ; it was covet- 

 ed with male flowers, and not a single female was to be seen. 

 Whether there is any truth in the observation, that in monoe- 

 cious plants one set of flowers sometimes so strongly predo- 

 minates, as to render the other imperceptible, and that a sort 

 of equality between the two sets of flowers only takes place, 

 as the plant advances in age, need not here be determined. 

 In the case before us, there seems to be no ground for such 

 a supposition. Perhaps all uncertainty concerning the Ca- 

 suarina in question will be removed by an accurate bota- 

 nical investigation.
