No. 570. 
CYTISUS NIGRICANS. 
Class. Order. 
DIADELPHIA DECANDRIA. 
A pretty flowering hardy shrub of mid- 
dling growth, seldom exceeding four feet in 
height. It is a native of Austria, and is 
said to have been introduced in 1730. It 
begins to produce its fine yellow flowers at 
an early age: they generally continue in 
succession during great part of the summer, 
and often perfect their seeds, by which it is - 
readily multiplied. 
It will thrive in any common soil, and 
we have never known it injured by our 
seasons.
