38. ELSHOLTZIA Willd. in Roem. & Ust. Mag. Bot. 11:3. 1790. 

 Herbs, with lliin mostly pelioled leaves, and small or minute clustered flowers, in ter- 

 minal bracted spikes. Calyx campauulate or ovoid, lo-nerved, scarcely oblique, enlarging 

 in fruit, not bearded in the throat, 5-loothed, the teeth nearly equal. Corolla-tube little 

 longer than the calyx, straight, or a little curved, the limb oblique, or slightly 2-lipped, 

 4-lobed; upper lobe erect, concave, emarginate, the 3 others spreading. Stamens 4, diver- 

 gent, didynamous, ascending, exsertcd, the upper pair shorter; anthers 2-celled, or the sacs 

 more or less confluent. Style 2-cleft at the summit. Ovary 4-parted. Nutlets ovoid or ob- 

 long, tuberculate, or nearly smooth. [Named in 

 honor of J. S. Elsholtz, a Prussian botanist.] 

 About 20 species, natives of Asia.

Family 26. SOLANACEAE Pers. Syn. i: 214. 1805. 

 PoT.\To Family. 

 Herbs, shrubs, vines, or some tropical species trees, with alternate or rarely 

 opposite, exstipulate entire dentate lobed or dis.sected leaves, and perfect regular 

 or nearly regular cymose flowers. Calyx inferior, gamosepalous, mostly 5-lobed. 

 Corolla gamopetalous, rotate, campauulate, funnelform, salverform or tubular, 

 mostly 5-lobed, the lobes induplicate-valvate or plicate in the bud. Stamens as 

 many as the lobes of the corolla and alternate with them, inserted on the tube, 

 all equal and perfect in the following genera, except in J\tu>iia, where 4 are 

 didynamous and the fifth smaller or obsolete; anthers 2-celled, apically or longi- 

 tudinally dehiscent. Disk present, or none. Ovary entire, superior, 2-celled 

 (rarely 3-5-celled); ovules numerous on the axile placentae, anatropous or 

 amphitropous; style slender, simple; stigma terminal; fruit a berry or capsule. 

 Seeds numerous, the te.sta sometimes roughened; embryo terete, spiral, curved, 

 or nearl)' straight; endosperm fleshy; cotyledons semiterete. 



About 70 genera and 1600 species, widely distributed, most abundant in tropical regions. 

 ■:;■ Fruit a pulpy berry; corolla plicate, its lobes generally induplicate. 

 Anthers unconnected, destitute of terminal pores, dehiscent. 

 Fruiting calyx bladdery-inflated. 



Fruiting calyx j-angled and deeply 5-parted; ovary 3-5-celled. i. Physalodes. 



Fruiting calyx 5lobed, not parted, lo-ribbed, often 5-ioangled, reticulated, wholly enclosing- 

 the berry; ovary 2cened. 

 Corolla open-campanulate, yellowish or whitish, often with a dark center; seeds with a 



thin margin, finely pitted. 2. Physalis. 



Corolla flat-rotate, violet or purple; seeds thick, rugose-tuberculate. 3. Oiiincuta. 

 Fruiting calyx somewhat enlarged, but closely fitted to the fruit, thin, obscurely veiny, open at 

 the mouth. 

 Corolla rotate, whitish ; lobes of fruiting calyx much exceeding the berry. 4. Leucoph vsalis. 

 Corolla rotate, whitish, sometimes tinged with purple; fruiting calyx not exceeding the 

 berry. 5. Chamaesaracha. 



Anthers connivent or slightly connate; fruiting calyx not enlarged. 



Anthers short or oblong, opening by a terminal pore or short slit in our species. 6. Sola num. 

 Anthers long, tapering from base to summit, longitudinally dehiscent. 7. Lycopetsicon. 



-X- -fc Fruit a nearly dry berry; corolla campanulate, little or not at all plicate, its lobes imbricated.
