longer than the leaves ; petals 7 mm. long ; fruit about 5 cm. long and 3.5 cm. 

 broad, thin, 3-lobed at apex. 



Doubtless through a slip of the pen, this species was listed by Pax * as " S. 

 mexicana Watson." 



2. TURPINIA Vent. Choix PI. Cels. 31. 1803. 

 Glabrous trees or shrubs ; leaves with 1 or more leaflets ; flowers perfect, in

 Veracruz ; type from Jalapa. 



Shrub or small tree ; leaves persistent, petiolate, the leaflet elliptic or elliptic- 

 oblong, 7 to 15 cm. long, abruptly short-acuminate at apex, entire or obscurely

? Lacepedea pinnata Schlecht. Linnaea 10: 240. 1835. 



Veracruz and Puebla. West Indies and Central America. 



Shrub or small tree ; leaflets elliptic-lanceolate, elliptic-oblong, or ovate- 

 lanceolate, 4 to 10 cm. long, acuminate or long-acuminate, crenate-serrate ; 

 panicles usually large but few-flowered; flowers 5 to 7 mm. long, white; fruit 

 1 to 1.5 cm. in diameter. 



Sehlechtendal's species was based upon fruiting material, but it is- probably 

 synonymous with T. occidentalis. Turpinia paniculata Vent, has been re- 

 ported from Mexico, and may perhaps occur there, since it is found in Central 

 America. It is distinguished by its smaller flowers.
