88 CJURYOPHYLLACE^E. (PINK FAMILY.) 



borne on a long terminal peduncle. (Name composed of o\os, all, and otrreov, 

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



TT. UMBELLATUM, L. Leaves oblong; peduncle and upper part of the stem 

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

 ter, Penn., Prof. Porter, and Morris Co., N. J., C. F. Austin. (Nat. from Eu.) 



9. 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. 

 Flowers white, in terminal cymes. Our species have the petals 2-cleft or ob- 

 cordate, the parts of the flower always in fives, and the exserted pods more or 

 less curved. (Name from Kepas, a horn, alluding to the shape of the pod in 

 many species.) 



C. visc6suM, L. (MOUSE-EAR CHICKWEED.) Annual, hairy and rather 

 clammy, nearly erect (4- 9' high); leaves ovate or obovate to oblong -spat ul ate : 

 bracts herbaceous; flowers small in close clusters at first, pedicels even in 

 fruit not longer than the acute sepals ; petals shorter than the calyx. (C. vul- 

 gatum, L. Herb., and Man. The names of this and the next were transposed 

 in the Linnaean herbarium, which has caused much confusion. They are here 

 applied as originally by Linnaeus, and by many recent botanists. Others sub- 

 stitute for this the later name, C. glomeratum, Thuill.) Grassy places, east- 

 ward and southward; not common. May -July. Stamens often 5. (Nat. 

 from Eu.) 



C. VULGA.TUM, L. (LARGER M.) Perennial; stems clammy-hairy, spread- 

 ing (6-15' long); leaves oblong; upper bracts scarious-margined ; flowers 

 larger (sepals 2-3" long), at first clustered, the fruiting pedicels longer, the 

 earlier ones mostly much longer than the obtuse sepals ; petals equalling the 

 calyx. (C. viscosum, L. Herb., and Man. C. triviale, Link.) Fields and 

 copses ; common, perhaps indigenous. May - July. (Nat. from Eu.) 



1. C. niitans, Raf. Annual, very clammy-pubescent; stems erect, slen- 

 der, grooved, diffusely branched (6 - 20' high) ; cyme loose and open, many- 

 flowered ; leaves oblong-lanceolate, acute, the lowest spatulate ; peduncles mostly 

 elongated ; petals longer than the calyx ; pods nodding on the stalks, curved 

 upward, thrice the length oj the calyx. Moist places, Vt. to Minn., and south- 

 ward. May - July. 



2. C. arvense, L. (FIELD CHICKWEED.) Perennial; stems ascending 

 or erect, tufted, downy or nearly smooth, slender (4-8' high), naked and/ew;- 

 several-flowered at the summit; leaves linear or narrowly lanceolate ; petals ob- 

 cordate, more than twice the length of the calyx ; pods scarcely longer than the 

 calyx. Dry or rocky places. May - July. (Eu.) 



Var. oblongifblium, Holl. & Britt. Usually taller, pubescent; leaves 

 narrowly or broadly oblong or oblong-lanceolate ; pod about twice longer than 

 the calyx. (C. oblongifolium, Torr.) Rocky places, N. Y. to. Minn., and 

 southward. Var. viLL6suM, Holl. &" Britt. Similar but densely villous-pu- 

 bescent, and the leaves lanceolate to ovate-lanceolate. E. Penn. 



10. S A GIN A, L. PEARLWORT. 



Sepals 4 or 5. Petals 4 or 5, undivided, or often none. Stamens as many 

 as the sepals, rarely twice as many. Styles as many as the sepals and alter- 

 nate with them. Pod many-seeded, 4 - 5-valved to the base ; valves opposite
