wetted. 
1l. Polemonium réptans L. Foliage glabrous. Stems erect or finally spreading,

FAMILY 6. SOLANACEAE Pers,  PorATO FAMILY. 
Herbaceous plants, or shrubs or vines, some of them of great economic value, 
possessing stimulant and narcotic properties. Leaves alternate, commonly with- 
out stipules: blades various. Inflorescence variously disposed. Flowers usually 
regular, perfect, on naked pedicels. Calyx free, of 5 or rarely 4-6 more or less 
united sepals, mostly persistent, sometimes accrescent. Corolla wh gs Shere 
rotate, campanulate, infundibuliform or hypocrateriform: limb 5-lobed or yd 
lobed. Androecium of 5, or 4 or 6 stamens, all fertile, adnate to the tube of DE 
corolla alternate with the lobes. Filaments equal or unequal, often toot 
Anthers introrse, opening lengthwise, or by pores. Gynoecium pega pees 
Ovary superior, 2-celled or sometimes 3-5-celled. Styles terminal, un n 
Stigmas entire or essentially so. Ovules numerous, amphitropous. Frui 1 
berry or a capsule, with two or rarely several cavities. Seeds numerous, nn 
with a crustaceous often tuberculate or rarely membranous testa. Endospe 
fleshy, plentiful.
