| Order XCV. SOLANACEZ. 
Solanacee, Benth. et Hook. Gen. Plant. ii. p. 882. 
Herbs or shrubs, rarely arboreous, generally dispersed in warm and temperate regions, 
The Order contains sixty-six genera, embracing about 1250 species, according to 
Bentham and Hooker’s calculation, and upwards of 1800 species according to Dunal 
and Miers. 
1. LYCOPERSICUM. 
Lycopersicum, Mill. Dict., ex Benth. et Hook. Gen. Plant. ii. p. 888. 
Three or four herbaceous species indigenous in Tropical America, commonly culti- 
vated and now naturalized in many other parts of the world. 
1. Lycopersicum esculentum, Mill. Dict. n.2; Dunal in DC. Prodr. xiii. 1, 
p. 26; A. Gr. Synop. Fl. N. Am. ii. p. 226. 
Common in Mexico and Central AMERICA, as well as in other parts of TROPICAL 
AMERICA and the West InvigEs; but it is difficult to determine where it is really 
indigenous and where it is only naturalized. Hb. Kew. 
2. SOLANUM. 
Solanum, Linn. Gen. Plant. n. 251; Benth. et Hook. Gen. Plant. ii. p. 889. 
Herbs, shrubs, or small trees, chiefly inhabiting tropical and subtropical regions, and 
especially numerous in America; a few occur in temperate regions, both north and 
south. Upwards of 900 species have been described; but a thorough revision would 
doubtless result in a considerable reduction of the number. 
The unnamed species of Solanum in Kew herbarium from Mexico and Central 
America are numerous, and include doubtless some undescribed ones, as well as most 
of those enumerated below.
