The Manual of the Botany of the Northern United States Part 124

10. C. glomerata, Choisy. Flowers _very densely cl.u.s.tered_, forming knotty ma.s.ses closely encircling the stem of the foster plant, much imbricated with scarious oblong _bracts, their tips recurved-spreading; sepals nearly similar_, shorter than the oblong-cylindrical tube of the corolla; stamens nearly as long as the oblong-lanceolate obtuse spreading or reflexed corolla-lobes; style several times longer than the ovary.--Wet prairies, Ohio to Minn., Kan., and Tex., mostly on tall Compositae. The rope-like twists (--' thick), of white flowers with golden yellow anthers imbedded in a ma.s.s of curly bracts, have a singular appearance.

ORDER 74. SOLANaCEae. (NIGHTSHADE FAMILY.)

_Herbs (or rarely shrubs), with colorless juice and alternate leaves, regular 5-merous and 5-androus flowers, on bractless pedicels; the corolla imbricate or valvate in the bud, and mostly plaited; the fruit a 2-celled (rarely 3--5-celled) many-seeded capsule or berry._--Seeds campylotropous or amphitropous. Embryo mostly slender and curved in fleshy alb.u.men. Calyx usually persistent. Stamens mostly equal, inserted on the corolla. Style and stigma single. Placentae in the axis, often projecting far into the cells. (Foliage rank-scented, and with the fruits mostly narcotic, often very poisonous, while some are edible.)--A large family in the tropics, but very few indigenous in our district. It shades off into Scrophulariaceae, from which the plaited regular corolla and 5 equal stamens generally distinguish it.

1. Solanum. Anthers opening by pores or c.h.i.n.ks at the tip.

[*][*] Corolla various, not wheel-shaped, nor valvate in the bud.

Anthers separate.

[+] Fruit a berry, closely invested by an herbaceous (not angled) calyx.

2. Chamaesaracha. Corolla plicate, 5-angulate. Pedicels solitary, recurved in fruit.
