Capsule globose-ovoid to conic or long beaked; scales present, prominent, or but fringed wings 

 along stamen attachment. 



Flowers about 1 mm. long, frequently tetramerous; corolla lobes with inflexed tips 



C. harpcri (p. 63). 



Flowers larger, nearly always pentamerous; corolla lobes not inflexed at the tips. 



Capsule globose, flask-shaped with a long neck; flowers relatively large 



C. rostrata (p. 63). 



Capsule globose-ovoid or conic. 



Calyx lobes ovate, obtuse, mostly even; capsule globose-ovoid, more or less 

 pointed. 

 Capsule 3-5 mm. wide; scales ordinarily not truncated or bifid; styles 



usually at least one-third the length of the capsule . C. gronovii (p. 64). 

 Capsule 3-6 mm. wide; scales truncated or bifid; styles relatively shorter, 

 usually about one-fourth the length of the capsule. . C. air la (p. 67). i/ 



Calyx lobes orbicular, denticulated; capsule globose-ovoid 



C. denticulata (p. 68). 



Calyx lobes deltoid or lanceolate, acute to acuminate. 



Scales reaching the filaments, bridged at about the middle 



C. veatchii (p. 69). 



Scales shorter than the tube, shallowly fringed or reduced to wings, bridged 

 below the middle. 

 Calyx lobes shorter than the tube, overlapping; flowers 5-6 mm. 



long C. suhindiisa (p. 69). 



Calyx lobes equalling the tube, not overlapping; flowers 2-4.5 mm. 

 long C. salina (p. 70) .

C. glandulosa (Engelmann) Small, Flora So. East. U. S., p. 969, 1903. 



C. ohhisiflora glandulosa Engelmann, Trans. Acad. Sci. St. Louis, 1:492, 1859. 



Stems medium. Flowers glabrous, about 2 mm. long, pentamerous. 

 subsessile to sessile in globular, compact clusters; calyx shorter than or 

 nearly as long as the corolla tube; lobes ovate, obtuse, slightly overlapping; 

 corolla campanulate; lobes shorter than the tube, ovate, obtuse, upright 

 to spreading, often becoming reflexed as the fruit matures; scales as long 

 as the tube, fimbriate, prominent, or somewhat shorter and slightly bifid; 

 stamens shorter than the lobes; filaments longer than the oval anthers and 

 somewhat subulate; styles longer than or equal to the globose ovary. 

 Capsule depressed-globose, angled by the developing seeds; seeds ordinarily 

 two to four in each capsule, brown, oval; hilum oblique or transverse and 

 at one side, oblong. 



The whole flower is more or less dotted with glandular-like cells and 

 reddish. This species, which in many respects resembles C. polygonorum, 

 differs in the pentamerous flowers, with more prominent scales and in the 

 obtuse corolla lobes. 



Type locality: Georgia. Range: Throughout the southern United 

 States from California to Florida and in the Greater Antilles and northern 

 Mexico.
