STANDLEY TEEES AND SHRUBS OF MEXICO. 1227 



1. Ehretia tinifolia L. Syst. Nat. ed. 10. 936. 1759. 

 Tamaulipas, Veracruz, Oaxaca, and Yucatan. West Indies. 



Shrub or tree, glabrous throughout or nearly so, sometimes 27 meters high, 

 with dense crown, the bark rather smooth ; leaves petiolate, oblong to ovate, 

 5 to 12 cm. long, rounded to acutish at apes, obtuse or rounded at base, 

 lustrous ; panicles longer than the leaves, dense or open ; corolla white, about 

 4 mm. long ; fruit 5 to 6 mm. in diameter, red or purple. " Nandimbo " 

 (Oaxaca) ; " manzana " (Tamaulipas, Veracruz) ; " manzanita " (Tamanlipas) ; 

 " roble," " beec," "bee," " satico " (Yucatan) ; " capulln cimarron " (Oaxaca); 

 " roble prieto " (Cuba). 



The fruit is edible. The tree is often planted for shade. 



The description of E. longifoUa Miers,^ which was based partly upon speci- 

 mens from Jamaica and partly upon a specimen collected between Tehuac^n 

 and Oaxaca, suggests this species, and Miers's name is probably to be reduced 

 to synonymy. 



2. Ehretia elliptica DC. Prodr. 9: 503. 1845. 



Ehretia ciliata Miers, Ann. Mag. Nat. Hist. IV. 3: 111. 1869. 



Ehretia exasperata Miers, Ann. Mag. Nat. Hist. IV. 3: 112. 1869. 



Coahuila to Guanajuato, Veracruz, and Tamaulipas. Western Texas. 



Shrub or tree, sometimes 15 meters high ; bark thick, fun-owed, separating 

 into thin, gray or reddish scales; leaves oblong to rounded, 3 to 7 cm. long, 

 usually rounded or obtuse at base and apex, thick, very scabrous or some- 

 times glabrate beneath ; panicles small, dense or open ; flowers sweet-scented ; 

 corolla 6 to 7 mm. long ; fruit 5 to 8 mm. in diameter, yellow ; wood hard, 

 weak, brown, close-grained, it specific gravity about 0.64. " Manzanita," 

 " manzanillo " (Tamaulipas); " anacua " (Nuevo Leon, Tamaulipas, Texas); 

 " anagua " (Nuevo Le6n) ; " anacahuite " (Guanajuato). 



In Texas the tree is known as " sugarberry," " nockaway," and " knack- 

 away," the last two names being corruptions of the Mexican " anacua," which 

 is itself an abbreviation of " anacahuite." The tree is often planted because 

 of its dense foliage and handsome flowers. The wood is used for wheel spokes, 

 axles, tool handles, and j'okes. The fruit is sweet and edible.
