difficult to distinguish: the most ornamental are A. puniceus, Nov£e Anglic, pulchellus, and macrophyllus. 
A. chinensis is a well known border annual ; of which there are varieties of different colors, and semi- 
double, and double. It is raised on a hotbed, and transplanted into the open ground in April or May.
