CYRILLA (after Dominico Cyrillo, professor of medi- 

 cine at Naples, 1734-1799). Cyrilldcese. Woody or

 handsome bright green foliage, and graceful racemes of 

 white fls., hardy north to N. Y. Thrives best in humid 

 sandy soil and shady position. Prop, by seeds and 

 cuttings under 

 glass, with slight 

 bottom heat.
