ORDER LXXVIL CAMPANULACE.E. BELLWORTS. 



Herbs with a milky juice, alternate leaves and without stipules. 



Fin. mostly blue, showy. Cal. superior, generally 5-cleft, persistent 



Cur. regular, campanulate, generally 5-cleft, withering, valvate in aestivation. 



Sta. inserted with the corolla upon the calyx, equal in number to, and alternate with, its lobes. 



Anth. Distinct, 2-celled. Pollen spherical. 



Ova. adherent to the calyx, 2 or more-celled. Style covered with collecting hairs. 



Fr. Capsule crowned with the remains of the calyx, loculicidal. Seeds many. 



Genera 28, species 500, chiefly abounding in the northern temperate zone and in South Africa. Of its 

 300 species, according to Alphonse DeCandolle, only 19 inhabit the torrid zone. The campanulaceK are 

 interesting chiefly for their beauty, being destitute of any important known properties.
