SOLAN ACE.E. (NIGHTSHADE FAMILY.) 267 



nosce and Compositce. Across the continent, principally through its southern 

 borders. 



3. C. inflexa, Engelm. Like the last: flowers of the same structure, 

 hut only a line long, generally 4-merous ; corolla deeper, with erect lobes, finally 

 capping the capsule: scales reduced to a few teeth. Open woods and dry prai- 

 ries, on shrubs (hazels, etc.) or coarse herbs, from Arkansas to Dakota and 

 eastward. 



= = Obtuse lobes of the corolla spreading. 



4. C. Gronovii, Willd. Stems coarse, often climbing high : corolla-lobes 

 mostly shorter than the deeply campauulate tube : scales copiously fringed : 

 capsule globose, umbonate. In wet shady places from the Rocky Moun- 

 tains eastward, most abundant in the Atlantic States, and everywhere very 

 variable. 



-i- -- Calyx of 5 distinct and largely overlapping sepals, surrounded by 2 to 5 or 

 more similar bracts : scales of corolla large and deeply fringed : capsule 

 mostly one-seeded, capped by the marcescent corolla: flowers on bracteolate pedi- 

 cels, in loose panicles. 



5. C. CUSpidata, Engelm. Stems slender : flowers l to 2^ lines long, 

 thin, membranaceous when dry : bracts and sepals ovate-orbicular : oblong 

 lobes of the corolla cuspidate or mucronate, rarely obtuse, shorter than the 

 cylindrical tube : styles many times longer than the ovary, at length exserted. 

 Prairies, on Ambrosia, Iva, Leguminosce, etc., from Colorado to Texas and 

 Nebraska. 



* * Capsule more or less regularly circumscissile, usually capped by the remains 

 of the corolla: styles capillary and lobes of the corolla acute. 



6. C. umbellata, HBK. Stems low and capillary : flowers l to 2 lines 

 long, few together in umbel-like clusters, usually shorter than their pedicels : 

 acute calyx-lobes and lanceolate-subulate lobes of the corolla longer than its 

 shallow tube : scales deeply fringed and exceeding the tube. Dry places, on 

 low herbs (Portulaca, etc.), from S. E. Colorado to Texas and Arizona. 



ORDER 55. SOLANACE^E. (NIGHTSHADE FAMILY.) 



Herbs, with alternate leaves, regular 5-merous and 5-androus flowers, 

 on bractless pedicels ; the corolla variously arranged in the bud, and 

 mostly plaited. Stamens mostly equal and all perfect, inserted on the 

 corolla. Style and stigma single. 



* Fruit a berry. 



i- Anthers longer than their filaments, either eonnivent or connate into a cone or cylinder : 

 corolla rotate : ca*lyx mostly unchanged in fruit. 



1. Solatium. Anther-cells opening at the apex by a 'pore or short slit, and sometimes 



also longitudinally dehiscent. 



-- +- Anthers unconnected, mostly shorter than their filaments, destitute of terminal pores, 

 dehiscent longitudinally. 



2. Chamaesaracha. Calyx herbaceous and closely investing the fruit or most of it, not 



angled. Corolla rotate, 5-angulate. Berry globose, its summit usually more or less 

 naked. Pedicels solitary in the axils, refracted or recurved in fruit.
