“ The species of the Genus Ruta are herbs or under shrubs 
natives of the temperate regions of the Eastern Hemisphere. 
The leaves are beset with small glands, containing a powerfully 
smelling oil : they are pinnate or much divided. The flowers 
are yellowish or greenish, and arranged in terminal corymbs 
or racemes. The Calyx has four persistent sepals ; the petals 
are four ; style one ; fruit capsular, 4-celled with 6-8 seeds in 
each cell.” 
The Common Rue (R. gravcolens, Linn.) a native of the 
South of Europe is commonly cultivated in England. It is a 
somewhat shrubby plant, 2-3ft. high, with pinnately divided 
bluish green leaves and yellowish corymbose flowers. The 
first that opens has usually ten stamens, the others have 
eight stamens only. These stamens are of unequal length ; each 
is bent inwards to touch the pistil, and after the pollen has 
been shed it bends back again. The powerful fetid odour 
and acrid taste of this plant depends on the presence of a 
volatile oil (M. T. Masters). 
Parts used : - The leaves, herb and oil.
