106. SCLEROCARPUS. 
Sclerocarpus, Jacq. in Act. Helvet. ix. p. 84; Benth. et Hook. Gen. Plant. ii. p. 364. 
This genus comprises about a dozen herbaceous species, inhabiting Tropical Asia and 
Africa and the warmer parts of America. 
1. Sclerocarpus dentatus, Benth. et Hook. Gen. Pl. ii. p. 364.

(Galeotti, 2062), Jalapa (Coulter, 360), valley of Cordova (Bourgeau, 1626), Campeche, 
Yucatan (Linden, 1246). Hb. Kew. 
There may be more than one species included under the above numbers. 
2. Sclerocarpus divaricatus, Benth. et Hook. Gen. Pl. ii. p. 364. 
Gymnopsis divaricata, Benth. Bot. Voy. ‘Sulphur,’ p. 116.

107. MONTANOA. 
Montanoa, Liav. et Lex. Nov. Gen. Mex. ii. p. 11; Benth. et Hook. Gen. Plant. ii. p. 364. 
Montagnea, DC. Prodr. v. p. 564. 
Shrubby, or sometimes arboreous. Bentham and Hooker estimate the species at 
about fourteen, ranging from Mexico to Colombia. Several of the following are only 
very imperfectly described; and the total number of species growing within our region 
is probably less than half the number enumerated below. 
1. Montanoa arborescens, DC. Prodr. v. p. 565. 
Montanoa atriplicifolia, Schz. Bip. in Seem. Bot. Voy. ‘ Herald,’ p. 304.

Late, Parkinson), Chiapas (Ghiesbreght). Hb. Kew. 
Schultz Bipontinus, in Seem. Bot. Voy. ‘Herald,’ p. 304, reduces this to his M. atri- 
plicifolia, apparently on the ground of adopting the oldest specific name.
