ORD. 31. CIRC^EACE^E. Juss. Enchanter's Nightshade 



Family. 



Calyx superior, deciduous, tubular, with a 2-parted limb. 

 Petals 2, alternate with the lobes of the calyx. Stamens 2, al- 

 ternate with the petals, inserted into the calyx. Disk large, 

 cup-shaped, filling up the whole of the tube of the calyx, and 

 projecting beyond it. Ovarium 2-celled, with an erect ovulum 

 in each cell; style simple, arising out of the disk; stigma einar- 

 ginate. Fruit 2-celled, 2-valved, 2-seeded. Seeds solitary, 

 erect; albumen none; embryo erect; radicle short, inferior. 

 Herbaceous plants. Leaves opposite, toothed, stalked. Flowers in 

 terminal and Lateral racemes, covered with undnate hairs. 



Obs. This order differs from Onagrariae in its large fleshy disk 

 which fills up the tube of the calyx, in its solitary erect ovula, and in 

 the binary division of the flower ; it is connected with that order through 

 Lopezia, with which it cannot however be absolutely associated, and 

 bears about the same relation to Onagrariae as is borne by Halorageae.

 Corolla of 2 petals. Capsules 2-celled. Cells 1 -seeded. 

 Name from the Enchantress Circe, either from the prettiness

 places, where plants used for incantations are found.
