+ + Stamens 4, didynamous, the fifth a sterile filament, included in throat of long- 
tubed corolla. 
13. Leptoglossis. Anthers somewhat reniform, confluent at summit: stigma or 
style under it petaloid-dilated. 
1. LYCOPERSICUM Tourn. (ToMATO, etc.) 
Chiefly annuals, with once or twice pinnate leaves, rounded petiolu- 
late leatlets, racemes of small flowers becoming lateral or opposite the 
leaves, articulated pedicels reflexed in fruit, rotate corolla, anthers con- 
nate in a cone and longitudinally dehiscent, and red or yellow pulpy 
berries. 
1. L. esculentum Mill., var. cerasiforme Gray. (CHERRY TOMATO.) Hirsute on 
branches and more or less glandular: leaves interruptedly 1 or 2-pinnate; larger 
leaflets incised and toothed, interposed smaller ones rounder and often entire: calyx 
little'shorter than yellow corolla: inflorescence bractless: berry globose and even, 
small. (LZ. cerasiforme Dunal.)—Spoutaneous on southern borders of Texas. Intro- 
duced from tropical America, and probably the normal form of the tomato of the 
gardens. 
2. SOLANUM Tourn. (NIGHTSHADE.) 
Herbs or shrubs, with larger leaves often accompanied by a smaller 
lateral one, mostly lateral and extra-axillary peduncles, 5-parted or 
cleft calyx and (rotate) corolla, exserted stamens with very short fila- 
ments and anthers converging around the style and opening at tip by 
two pores or chinks, and a usually 2-celled berry. 
* Fruit naked (not inclosed in the enlarging calyx, except no. 9): stamens all alike. 
+ Never prickly : anthers blunt: pubescence when present simple (except in no. 4). 
++ Leaves pinnate. 
1. S. tuberosum L., var. boreale Gray. Low, more or less pubescent: tubes about 
12 mm. in diameter: leaflets 5 to 7, ovate or oval,with few interposed small ones or 
none atall: peduncle few-flowered : corolla blue or white, angulate-5-lobed. (8. Fend- 
leri Gray.)—In the mountains west of the Pecos: Chenate mountains (Nealley). 8. 
tuberosum is the potato-plant, a native of South America, from which our plant 
seems not specifically distinct. 
++ ++ Leaves simple. 
2. 8. nigram L. (COMMON NIGHTSHADE.) Low annual, much branched and 
often spreading, nearly glabrous, rough on the angles: leaves ovate, wavy- 
toothed: flowers white, in small umbel-like lateral clusters, drooping: calyx spread- 
ing: filaments hairy: berries globular, black.—Common everywhere in damp or 
shady ground. In Texas and New Mexico, and extending southward, is var. NODI- 
FLORUM Gray, which is slender and often tall, with entire (rarely few-toothed) 
acuminate leaves, glabrous filaments, generally exserted style, and calyx reflexed 
in fruit. (S. nodiflorum Jacq.) 
3. S. triquetrum Cav. Nearly glabrous perennial, with suffruticose flexuous or 
sarmentose stems which are hardly climbing: branches angled but hardly trique- 
trous: leaves deltoid-cordate, varying to hastate, in smaller forms to hastate-3-lobed 
(or even 5-lobed) with the middle lobe lanceolate or linear and prolonged: cymes 
mostly umbellately few-flowered : corolla violet or purple (sometimes white): berries 
globose, red.—Low gtounds and thickets, throughout southern and western Texas. 
4, S. verbascifolium L. Erect shrub, very soft-tomentose throughout with 
stellate pubescence: leaves ovate, rounded at base (L0to 25 cm. long), entire, very
