D. Neapolitana is the other, and the common collina the 

 middle. 



" D. australis, if we may keep that name, grows in damp, 

 sandy, or marshy coppices which border the lagunes and 

 lower shores of the coast near Naples ; in gardens it will 

 stand a great deal of heat in light soil even in that climate, 

 but not in a hard or heavy one. This is also found to be 

 the case with the American Myricas, and some other plants, 

 in the climate of Italy, which in England are imagined not 

 to live without peat earth and shade : and a plant of this 

 genus, D. Cneorum, in its native light calcareous soil of 

 Austria, resists a very considerable summer heat. 



" The present species is plentiful on the banks of the lake 

 of Licola, and of the river Volturno and plain of S. Agata, 

 all near Naples. It seems to be perfectly hardy in Eng- 

 land."— W. F. S. 



The Hon. W. F. Strangways has favoured me with the 

 foregoing memorandum, as well as with the specimen from 

 which the figure of this interesting species has been 

 prepared.
