 Petals unknown. Fruit a little contracted from the sides (f. 56. 

 K. a.) ; mericarps ovate, rather didymous, with 5 hardly pro-

SUBORDER III. CCELOSPE'RM. Albumen involutely curved

TRIBE XVII. 



CORIA'NDRE^;. Fruit globose, or of 2 subglobose mericarps. 

 Mericarps furnished milk 5 primary, depressed, andflexuous ribs: 

 lateral ribs placed before the accessory margin ; and 4 more 

 prominent secondary ones ; all mingless.

 Carpophore bipartite, adnate on both sides. Involucra and in- 

 volucels wanting, or of 1 leaf. 



168 Asi6MA. All as in Bifora, but the fruit is evidently 

 didymous ; and the commissure is narrow, not perforated, nor
