32. BERBERIDACEAE. Barberry Family. 

 1. BERBERIS L. 



The cultivated barberry belongs to this genus. 



1. Berberis repens Lindl. Oregon grape. Common in woods and thickets at 

 low and middle altitudes. B. C. to Alta., Calif., and N. Mex. — Small shrub, usually 

 about 30 cm. high; leaves pinnate; leaflets 3 to 7, leathery, the teeth with bristly tips; 

 flowers yellow, in racemes; fruit blue, very juicy, sour, containing few large seeds. 



The leaves persist throughout the winter; in autumn they are handsomely tinted 

 with red or purple. The flowers appear in spring. The fruit is edible but too sour 

 to be very pleasant; it is often used for making jelly. A closely related species of 

 Oregon grape is the State flower of Oregon. The Blackfoot Indians used a decoction 

 of the roots as a remedy for stomach affections and for hemorrhages.
