 by 6 teeth. Seeds rough. Annuals or biennials, with several (white) flowers 

 in an umbel, borne on a long terminal peduncle. (Name composed of 6Aos, att, 

 and otrrfov, bone, by-antiphrasis, these plants being soft and tender.) 



1. H. UMBELLATUM, L. Leaves oblong ; peduncle and upper part of the 

 stem glandular-pubescent; pedicels reflexed after flowering. Hills around 

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



12. CERASTIUM, L. MOUSE-EAR CHICKWEED. 



Sepals 5, rarely 4. Petals as many, 2-lobed or cleft, rarely entire. Stamens 

 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- 

 ers white, in terminal cymes. (Name from Ke'pas, a horn, alluding to the shape 

 of the pods in many species.) 



1. Petals 2-cleft or obc.ordate : parts of the flower in Jives : pods (except in No. 5) 



longer than the calyx, and usually more or less curved.

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

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

 and the next were transposed by Linnaeus himself, and have consequently been 

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

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

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

 my hairy, spreading (6' - 15' long) ; leaves oblong, greener ; upper bracts scarious- 

 margined ; flowers at first clustered ; pedicels longer than the obtuse sepals, the 

 earlier ones in fruit much longer. (2) 1J. Grassy fields and copses. May - July. 

 A larger and coarser plant than No. 1, the flowers larger. (Nat. from Eu.) 

 * * Petals longer than the calyx.
