94 CARYOPHYLLACE.E. (PINK FAMILY.) 



transposed by Linnapus, and by continental botanists ever since.) Stamens 

 often 5. The var. ? SEMIDECANDRUM, which has more lengthened fruit-bearing 

 pedicels, is here hardly met with. (Nat. from Eu.) 



2. C. visc6suM, L. (LARGER M.) Perennial; stems clammy-hairy, 

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

 at first clustered, the fruiting pedicels longer, the earlier ones mostly much longer 

 than the obtuse sepals ; petals equalling the calyx. Fields and copses : common, 

 perhaps indigenous to the country. May- July. (Nat. from Eu.) 



3. C. niltans, 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 up- 

 wards, thrice the length of the calyx. Moist places, Vermont to Minnesota and 

 southward. May -July. Var. BRACHYPODUM, Engelm., W. Illinois and 

 southwestward, has pedicels shorter than the pods. 



4. C. oblongifblium, Torr. Perennial; stems ascending, villous (6'- 

 12' high), many -flowered ; leaves oblong-lanceolate and ovate; peduncles clammy- 

 hairy; petals (2-lobed) and ripe pods about twice the length of the calyx. Rocky 

 places, New York to N. Virginia and Illinois: rare. May -July. Stouter 

 and larger flowered than the following species. 



5. C. arv6nse, L. (FIELD CHICKWEED.) Perennial; stems ascending 

 or erect, tufted, downy, slender (4' -8' high), naked and few -several-flowered at 

 the summit ; leaves linear ; petals obcordate, more than twice the length of the 

 calyx ; pods scarcely longer than the calyx. Dry or rocky places, New England 

 to Wisconsin and northward. May -July. (Eu.) 



2. MCENCHIA, Ehrhart. Petals entire or merely refuse : the parts of the flower 

 commonly in fours : pod ovate, not longer than the calyx. 



6. C. QUATERNELLUM, Fenzl. Smooth and glaucous annual ; stem simple, 

 erect (2' -4' high), 1-2-flowered; leaves lanceolate, acute; petals not exceed- 

 ing the calyx ; stamens 4. (Sagina erecta, L. Moenchia quaternella, Ehrh.) 



Near Baltimore, in dry ground. (Adv. from Eu.) 



10. SAGINA, L. PEARLWORT. 



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

 as the sepals, rarely twice their number. Styles as many as the sepals and al- 

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

 the sepals. Little, matted herbs, with thread-like or awl-shaped leaves, no 

 stipules, and small flowers terminating the stems or branches; in summer. 

 (Name from sagina, fattening; of dubious application.) 



* Parts of the flower in fours, rarely with some few inflves. 



1. S. procumbens, L. Perennial, depressed or spreading on the ground, 

 glabrous ; leaves linear-thread-shaped ; apex of the peduncle often hooked soon 

 after flowering ; petals shorter than the broadly ovate obtuse sepals, sometimes none. 



Springy places and damp rocks, coast of Maine to Pennsylvania. (Eu.) 



2. S. apdtala, L. Annual, erect, with more slender leaves, narrower sepals, 

 and petals none or obsolete. Dry soil, New York and Pennsylvania to Illinois : 

 scarce, seemingly native? (Eu.)
