 linear or linear-subulate, about 1 mm. long, acute : petals elliptic, about 2 mm. long, 

 curved and concave, thickened at the apex : stamens shorter or just about as long as the 

 petals : filaments shorter than the anthers : carpels usually solitary, about 5 mm. in diam- 

 eter, glandular-punctate, apiculate : seeds solitary, obliquely-ovoid, black, shining. [A'o?;-
