338 SOL ANA'JEJE. (NIGHTSHADE FAMILY.) 



with a smaller, slenderer, more exserted corolla ; C. (Lepidanche) adpres&, 

 Enijdm., is the Western form, with a larger, shorter, nearly included corolla. 

 Both grow almost entirely on shrubs; the first in the Alkghanies, from Pennsyl- 

 vania southward ; the latter from Western Virginia to the Mississippi and 

 Missouri, in fertile shady bottoms. The clusters in fruit are sometimes 2' in 

 diameter. 



9. C. gloillCl'Jfifa, Choisy. Flowers very densely clustered, forming 

 knotty masses closely encircling the stem of the foster plant, much imbricated 

 with scarious oblong bracts ivith recurved-spreadinq tips ; sejxils nearly similar, 

 shorter than the oblong-cylindrical tube of the corolla; stamens nearly as long 

 as the oblong-lanceolate obtuse spreading or reflexcd lobes of the corolla; scales 

 large, fringed-pinnatifid ; styles slender, longer than the pointed ovary ; the 

 pointed pod mostly 1 - 2-seeded. (Lepidanche Compositarum, Enyelm.) Moist 

 prairies, from Ohio and Michigan south-westward : growing mostly on tall Com- 

 posite. The orange-colored stems soon disappear, leaving only the close coils 

 of flowers, appearing like whitish ropes twisted around the stems. 



ORDER 82. SOL, AN AC E^. (NIGHTSHADE FAMILY.) 



Herbs (or rarely shrubs), with a colorless juice and alternate leaves, regu- 

 lar b-merous and b-androus flowers, on bractlexs pedicels ; the corolla plaited- 

 imbricate, plaited-convolute, 'or infolded-valvate in the bud, and the fruit a 

 ^-celled (rarely 3 - b-celled) many-seeded pod or berry. Seeds campy- 

 lotropous or amphitropous. Embryo mostly slender and curved in fleshy 

 albumen. 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 and usually the fruits more or less narcotic, 

 often very poisonous.) A large family in the tropics, but very few indige- 

 nous in our district. It shades off into Scrophulariaceae, from which the 

 plaited regular corolla and 5 equal stamens generally distinguish it.
