Spines numerous, very slender. 

 Petals half as long as the sepals or shorter. 



21. T. galeottiana. 

 Petals nearly as long as the sepals 22. T. discolor. 



1. Triumfetta lappula L. Sp. PI. 444. 1753. 



Morelos, Oaxaca, and probably elsewhere. West Indies, Central America, 

 and western Africa. 



Slender shrub, 1.5 to 3 meters high ; leaves long-petiolate, ovate or rhombic, 

 often trilobate, dentate, acute or acuminate, finely stellate-pubescent ; sepals 

 3 to 4 mm. long, densely tomentose ; fruit (including spines) 6 to 8 mm. in 

 diameter, stellate-pubescent, the spines slender. " Mozote de caballo " (Costa 

 Rica, Nicaragua); " pega-pega " (Panama); " cadillo " (Porto Rico); " mata 

 de negro" (Santo Domingo). 



The bark furnishes a fine and strong fiber. The leaves and bark contain a 

 sweet, slightly astringent mucilage, and an infusion is used in Costa Rica as 

 a remedy for colds. The plant is used also to purify or clarify syrup, in mak- 

 ing native sugar. 



2. Triumfetta semitriloba Jacq. Enura. PI. Carib. 22. 1760. 

 1 Triumfetta althacoides Lam. Encycl. 3: 420. 1789. 



Sinaloa to Tamaulipas, Yucatan, and Chiapas. West Indies, Central America, 

 and South America. 



Slender shrub, 1 to 3 meters high ; leaves ovate to rhombic, long-petiolate, 

 acute or acuminate, rounded or cordate at base, often shallowly lobed ; sepals 

 5 to 7 mm. long ; petals yellow, about equaling the sepals ; fruit 6 to 8 mm. 

 in diameter, the body glabrate in age, the spines slender. " Majalmilla," 

 " majahuilla " (Sinaloa); "cadillo" (Tabasco, Veracruz, Porto Rico, Co- 

 lombia) ; "ochmul" (Yucatan) ; " abrojo " (Colima) ; " huizapotillo " (Jalisco, 

 Urbina) ; "cadillo malva " (Tamaulipas); " guizazo," " guizazo de cochino " 

 (Cuba); " escobilla amarilla " (Guatemala). 



Like the other species, this plant has tough fiber, which has been used for 

 making rope, coarse cloth, and, in Brazil, paper. The roots are mucilaginous 

 and astringent, and they are said to have diuretic properties. Locally they are 

 administered for venereal diseases and for liver and kidney affections. 



3. Triumfetta dumetonim Schlecht. Linnaea 11: 377. 1837. 

 Triumfetta lindeniana Turcz. Bull. Soc. Nat. Moscou 31': 229. 1858. 

 Triumfetta lotteriana Turcz. Bull. Soc. Nat. Moscou 32*: 260. 1859. 

 Veracruz and Oaxaca ; type from Jalapa, Veracruz. Guatemala. 



Shrub, 1 to 2 meters high ; leaves long-petiolate, broadly ovate to oblong- 

 lanceolate, acuminate, rounded or obtuse at base, sometimes lobate, duplicate- 

 serrate, green beneath and thinly stellate-hirsute; calyx 6 to 8 mm. long, often 

 glabrate ; petals equaling the sepals, yellow ; fruit 8 to 10 mm. in diameter, 

 with very slender spines. 



It is not improbable that some earlier name, based upon a West Indian or 

 South American plant, may be found for this species.

 Triumfetta macrocalyx Turcz. Bull. Soc. Nat. Moscou 31': 230. 1858.
