CEENOPODIACE^E. (GOOSEFOOT FAMILY.) 407 



2. C. Album, L. (Lamb's-Quarters. Pigaa'eed.) Erect (1°- 3° high), 

 mealy and pale, sometimes green and the mealiness obscure ; leaves varying from 

 rhombic-ovate to lanceolate or the uppermost even linear, acute, all or only the lower 

 more or less angulate-toothed ; clusters spikecl-panicled, mostly dense; seed Avith 

 acute or bluntish margins. — Common, especially in cult, ground : extremely 

 A-ariable. — The genuine C. album is considerably Avhitish-mealy, at least the 

 inflorescence, which is dense ; the calyx with strongly keeled lobes, and com- 

 pletely enclosing the fruit. A green form Avith somewhat entire leaA-es and less 

 dense inflorescence is C. viride, L. (Nat. from Eu.) 



Var. BosciAxum. Loosely branched, more slender, the mealiness obscure 

 or slight and only on the inflorescence, which is laxer, the floAvers smaller ; calyx 

 incompletely covering the fruit, its lobes moderately or slightly if at all keeled ; 

 leaA r es inclined to be entire. (C Boscianum, Moguin. C. Berlandieri, Moquin, 

 an intermediate form. C. polyspermum, var. spicatum, Ed. 2.) — More shady 

 places, Pennsylvania and soutliAvard. In some forms appears as if a distinct 

 species ; seemingly indigenous south westward. 



3. C. glaucum, L. (Oak-leaved Goosefoot.) Loav (5'- 12' high), 

 spreading, glaucous-mealy, leaves sinuately pinnati fid-toothed, oblong, obtuse, pale 

 green above ; clusters spiked, small ; calyx-lobes not at all keeled ; seed sharp- 

 edged, often vertical. — Streets of towns : rather scarce. Brackish borders of 

 Onondaga Lake. (Nat. from Eu.) 



4. C. urbicum, L. Rather pale or dull green, nearly destitute of meali- 

 ness, Avith erect branches (l°-3° high); leaves triangular, acute, coarsely and 

 sharply many-toothed ; spikes erect, crowded in a long and narrow racemose panicle ; 

 calyx-lobes not keeled ; seed ivith rounded margins. — Var. rhombifolium, 

 Moquin (C. rhombifolium, Muhl.), is a form Avith the leaA'es more or less Avedge- 

 shaped at the base, and Avith longer and sharper teeth. — Not rare eastward. 

 (Nat. fromEu.) 



5. C. murAle, L. Resembles No. 4, but less erect, loosely branched ( 1° - 1 £° 

 high) ; leaves rhomboid-ovate, acute, coarsely and sharply unequally toothed, thin, 

 bright green; spikes or racemes diverging, somewhat corymbed ; calyx-lobes scarcely 

 keeled ; seed sharp-edged. — Boston to Illinois : rare. (Adv. from Eu.) 



6. C. hybridum, L. (Maple-leaved Goosefoot.) Bright green 

 throughout; stem Avidely much branched (2° -4° high); leaves thin (2 ! -8' 

 long), someAvhat triangular and heart-shaped, taper-pointed, sinuate-angled, the 



, angles extended into a few large and pointed teeth; racemes diffusely and loosely 

 panicled, leafless ; calyx not fully covering the fruit, its lobes keeled ; seed sharp- 

 edged, the thin pericarp adhering closely to it. — Common. Heavy-scented, like 

 Stramonium. (Nat. from Eu.) 



§ 2. BOTRYOIS, Moquin. (Ambrina, Moquin, in part.) Not mealy, but 

 more, or less viscid-glandular and pleasant-aromatic : seed frequently vertical, 

 obtuse-edged : embryo forming only two thirds or three quarters of a ring. 



7. C. B6trys, L. (Jerusalem Oak. Feather Geranium.) Glan- 

 dular-pubescent and viscid; leaves slender -petioled, oblong, obtuse, sinuate pin- 

 natifid ; racemes cymose-diverging, loose, leafless; fruit not perfectly enclosed. — 

 Escaped from gardens. (Adv. from Eu.)
