EVOLVULUS and akin 
I have several N. American sp. that would

868. STYLISMA R. 1817. fl. tell, calix sim-

sub-tendentate, filaments 5 subequal villose at 
base, anthers sagittate, disk annular, style bi- 
parted, 2 stigmas globose, capsule 41ocular 
4sperme. — Perennials , 'peduncles axillary— 
The true Evolvulus differs by corolla rotate 
5fid, capsule 2locular 4valve disperme, 2styles.
