Dipldcus puniceus. This shrubby (inimulus) plant was 

 introduced by Mr. Nuttall, from California, by seeds, in 1836, 

 and sent by us to England, in 1837. The flowers are of a 

 scarlet orange, about one inch and a half long, and produce in 

 pairs, from the axils of the leaves, or young wood; the plant 

 requires considerable nourishment, for the more rapid it 

 grows, the more profuse are its flowers, which bloom from 

 May to September, and are rath ^r showy. In the Southern 

 States it will prove a hardy shrun, blooming nearly the whole 

 year. (Soil No. 12.)
