 Corolla pure white {TFoolls), spreading to 5 or 6 lines diameter, very deeply 

 divided iuto oLlong-lauceolate lobes, sbglitly pii])escent inside. Corona-

 sender. Leaves oblong oblauceolate lanceolate or linear, obtuse luucronate 

 or acute, rather thick and almost veinless, 1 to 2 in. long, narrowed iuto a 

 short petiole. Flowers ''yellowish-green," in simple umbels or very short 

 racemes, on peduncles usually under \ in. long, the pedicels rather longer. 

 Calyx-segments narrow, acute, about \\ lines long. Corolla deeply divided 

 into narrow acuminate lobes of 3 to ^ lines. Corona-segments lanceolate, 

 acumiuate, longer than the anthers. Pollen-masses oblong, small. Pollicles 

 rather broad, acuminate, 2 to 3 in. long.—Oxpfehna carnosum, R. Br. Prod.
