 hifhest luxuriance: anions; them are several of the yellow-flowered 

 Bidenti folia, raised from seeds saved there last year, though the au-

The true Rosea of Cavanilles, Avith doubly j)innated leaves, is also 

 growinor most vigorously, and one of its stems has been pinched to 

 produce lateral shoots lor cuttings. A plant left in the middle of

 that there is not a doubt that this magnificent genus will soon be a 

 common ornament of the gardens in this island.
