STAKDLEY — TREES AND SHRUBS OF MEXICO. 199 



5 cm. long or smaller, short-petiolate, finely serrate ; flowers small, clustered, 

 appearing in autumn ; fruit 8 to 10 mm. long, hairy ; wood reddish brown, 

 rather weak, its specific gravity about 0.70. 

 The wood is used locally for furniture and wheel hubs.

The following is the only species of the genus, which was named in honor 

 of Senor Don Filemon L. Lozano, who assisted Pringle in his Mexican col- 

 lections. 

 1. Lozanella trematoides Greenm. Proc. Amer. Acad. 31: 236. 1905. 



Known only from the type locality, " Honey Station," near Trinidad, Hidalgo. 



Shrub or small tree, 2 to 6 meters high; leaves slender-petioled, ovate, 5 to 

 9 cm. long, acuminate, serrate, 3-nerved, thinly hairy beneath ; flowers dioe- 

 cious, small and green, the pistillate in axillary cymes ; perianth 5 or 6-parted ; 

 fruit a sessile ovoid greenish drupe.

Sponia micrantha Decaisne, Nouv. Ann. Mus. Paris 3: 498. 1834. 



Sinaloa to Veracruz and southward. Florida, West Indies, Central America, 

 and tropical South America. 



Shrub or small tree, 2 to 6 meters high or in some parts of its range still 

 larger, the trunk occasionally 10 to 15 cm. in diameter; leaves ovate, finely 

 serrate, 3-nerved, acute or acuminate, 5 to 12 cm. long, their pubescence vari- 

 able in amount; flowers very small, greenish white, cymose ; fruit small (about 

 1.5 ram. in diameter), globose, green or reddish; wood light, soft, close-grained, 

 light brown. " Ixpepe " (Veracruz); " equipal " (Michoacdn) ; " yaco de 

 cuero" (Oaxaca, Reko) ; " juc6," " capulln," "vara blanca " (Costa Rica); 

 " capull " (Guatemala); " masaquila " (Venezuela); " memiso " (Santo Do- 

 mingo); " palo de cabra," " guacimilla " (Porto Rico). 



The bark contains very strong fiber. The species of this genus seem to be 

 of little economic importance. T. coynmersonii Blume, of Madagascar, is highly 

 esteemed for medicinal purposes by the natives, and stomachic, astringent, 

 febrifuge, diuretic, and antisyphilitic properties are attributed to it. 



5. CELTIS L. Sp. PI. 1043. 1753. 



Large or small trees or shrubs, sometimes scandent, armed or unarmed; 

 leaves deciduous or somewhat persistent, entire or dentate, often unequal at 

 base; flowers small, the pistillate usually solitary and long-pedicellate; fruit 

 globose, with thin flesh and a large seed. 



The fruit of all the species is sweet and edible, especially in the spineless 

 species (hackberries or sugarberries), but the pulp is very scant. The Indians 

 of some parts of the United States seem to have been very fond of it. They 

 pounded the fruit fine, seeds and all, and ate it with fat or mixed with parched 

 com.'
