Calyx naked at the base, 5-toothed. Flowers dioecious ; the stamumte flowers 

 entirely destitute of pistils, with 15-20 anthers ; the fertile with a short column 

 of filaments but no anthers. Styles 8 - 10, stigmatic along the inside. Fruit 

 depressed-globular, separating when ripe into as many kidney-shaped 1 -seeded 

 beakflss and scarcely dehiscent carpels as there are styles. Radicle pointing 

 downwards. A tall and roughish perennial herb, with very large 9-11-parted 

 lower leaves, the pointed lobes pinnatifid-cut and toothed, and small white flow- 

 ers in panicled clustered corymbs. (Named by Clayton from vairrj, a wooded

5. SIDA, L. SIDA. 



Calyx naked at the base, 5-cleft. Petals entire, usually oblique. Styles 5 or 

 more : the ripe fruit separating into as many 1 -seeded carpels, which remain 

 closed, or commonly become 2-valved at the top, and tardily separate from the

 deft, the lobes oblong and pointed, toothed ; flowers (white] umbellate-corymbed,

 5, combined into an ovate fruit, each splitting at the top into 2 beaks. A little tu- 

 bercle at the base of the leaves on the stronger plants gives the specific name, 

 but it cannot be called a spine. Waste places, common southward and 

 eastward. (Nat. from Trop. Amer. or Afr.)
