I. Berberis. — Spinous shrubs with yellow wood and astringent 

 bark ; sepals 6, deciduous ; petals 6, each with 2 nectaries at the 

 base ; stajnens 6 ; fruit berrylike, i — 3-seeded. 



*2. Epimedium. — Sepals 4, deciduous ; petals 8, in two whorls,

I. Berberis (Barberry). — Leaves spinously-dentate, or reduced 

 to 3 — 7-fid spines ; yf^z£/(?r^ in racemes, yellow, with 2 or 3 minute 

 bracteoles. (Name said to be of Arabic origin.) 



I. B. vulgaris (Barberry). The only British species. A pretty 

 shrub, not uncommon in woods and hedges, with yellow wood 

 and 3-forked spines. Its )^^\\o\^ fiozvers hang in drooping clusters ; 

 the filame?its are elastic and irri- 

 table, so that when touched ever 

 so lightly by the leg of an insect 

 they spring upward and throw their 

 pollen outward. The oblong berry- 

 like fruits are orange-red when ripe 

 and gratefully acid, and may be made 

 into an agreeable preserve. The 

 shrub is often rooted out by farmers, 

 as a fungus which lives part of its 

 life on Barberry leaves is the cause 

 of '* rust " in wheat. Several species 

 furnish a yellow dye, and others 

 are cultivated in gardens, as are 

 also several members of the allied 

 genus Mahbnia. — Fl. May, June.
