 minea Hooker, S. atropurpurae Graham, S. picta Sweet, S. Barclayana Sweet, S. hybrida Hort. 

 and S. variabilis Hort., is a native of Chili and was introduced into Europe about 1830. Sev- 

 eral other Chilian species, S. fulva, S. integrifolis, S. intermedia, and S. linearis were also 

 introduced at about the same period, but these, together with S. sinuata coccinea and S. stra- 

 minea picta have disappeared from cultivation, so that at the present time <S. sinuata and its 

 dwarf variety alone persist. The plants are readily grown out of doors and the flowers possess 

 a wide range of harmonious colors. — E. J. Kraus.
