 Btem glandular-pubescent; pedicels reflexcd after flowering. Hills around 

 Lancaster, Pennsylvania, abundant, Prof. Porter. (Adv. from Eu.)

 twice as many, or fewer. Styles equal in number to the sepals, and opposite 

 them. Pod 1-celled, usually elongated, membranaceous, opening at the apex by 

 twice as many teeth as there were styles, many-seeded. Seeds rough. Flow-

 of the pods in many species.) 



$ 1. Petals 2-cleft or obcordate : parts of the flower in fives : pods (except in No. 5)

 flowers (small) in very close clusters at first ; pedicels even in fruit not longer 

 than the acute sepals. (1) @ Grassy banks. May -July. The names of this

 differently applied by different authors ever since. This is the C. vulgatum of 

 English botanists, and of the Linnasan herbarium : but the next is so called in 

 Sweden and on the Continent generally. (Nat. from Eu.)
