Barberry. 



Calyx calyculate with 3 or sometimes 2 close-pressed 

 bractlets : proper sepals 6, in two series, alternatively im- 

 bricated in aestivation, orbicular or obovate, concave-spread- 

 ing, more or less petaloid, deciduous. Petals 6, opposite 

 the 6 sepals, imbricated in aestivation in two series, hypogy- 

 nous, obovate, concave-connivent, unguiculate or sessile, 

 marked with two thickened glands, or more or less conspicu- 

 ous glandular spots, at the base of the lamina inside, decidu- 

 ous. Stamens 6, hypogynous, opposite the petals and short- 

 er than they : filaments thick, articulated with the recep- 

 tacle, spreading under the petals in the expanded flower, 

 starting forward towards the pistil with a sudden jerk when 

 touched with a point next the base on the inner side (thus 

 projecting the pollen upon the stigma): anthers two-celled; 

 the cells somewhat extrorsely adnate to the thick connec- 

 tive, nearly the whole face separating as a valve which is 

 lightly hinged at the apex. Ovary ovoid, one-celled, mark- 

 ed with a projecting placental line inside (toward the axis) : 

 style short and thick or none: stigma orbicular and peltate, 

 umbilicate, entire. Ovules 2 to 9, erect from the base ol 

 the placental line, towards which (he raphes are all turned
