JS''ectanferous glands 3, one under each of the 

 ^ upper calix leaves, the lower one without a 

 gland. Calix 4-Ieaved, small and deciduous. 

 Petals 4, all ascending to one side. Capsule si- 

 liquose, stipitate, 1 -celled, 2-valved. 



Principally annual plants, disagreeably scented, and 

 somewliat actively dcletereous; leaves producing 2 glands 

 or 2 spines at the base, simple, ternate, or digitate; flow- 

 -ers axillary, or in terminal racemes, pedicells bracteate. 

 Stamina 4, 6, 12, 20, or more. 



S FECI Es. 1. C. pentaphylla. — Flowers white, extremely 

 singular. Calix small, green, and distinctly 5-leaved. 

 Petals roundish, upon capillary claws 3 times their length. 

 Stamina 6, very long, originating about the middle of the 

 styloid pedicell which supports the fruit; anthers linear 

 and never curved. — In confirmation, in some measure, of 

 the sagacious suspicions of Linn?eiis, I have now before 

 me a somewhat viscidly pubescent specimen, in which the 

 peduncles produce now and then a distinct prickle, thus 

 proving the near affinity of this species to C. heptaphylla 

 and C. triphijlla. 2. dodecandra. Common on the sandy 

 chores of lake Erie, near Buffaloe creek, also along the 

 margins of the Misslsippi and the Missouri. Flowers 

 white. Pods large and sessile. The whole plant more 

 or less viscid and foetid. 3. * cune'fulia. Muhl. Catal.
