Chihuahua and Coahuila to San Luis Potosl. Western Texas (type lo- 

 cality) and southern New Mexico. 



Shrub, 1 to 4.5 meters high ; leaflets mostly 3 to 5 cm. long, very thick and 

 rigid, pale, especially beneath, with large spiny lobes or teeth ; fruit red. 

 "Agritos " (Coahuila, Nuevo Leon, Texas); " agrillo '' (San Luis Potosf, 8af- 

 ford) ; " palo amarillo" (Chihuahua, Nuevo Leon, Durango). 



In Texas and New Mexico the name " agrito " is corrupted into " agarita " 

 or even " algerita." 



The wood is sometimes used for tanning and for making ink. Like that of 

 other species, it yields a yellow dye. The acid fruit is utilized for jelly, 

 preserves, and tarts, and wine has been made from it. The roasted seeds are 

 said to have been used as a coffee substitute. A decoction of the root is 

 reported to be employed in Texas as a remedy for toothache. The flowers- are 

 said to supply bees with a good quality of honey. 



This is presumably the species to which Berlandier ^ gives the name Chi-yso- 

 dendron tinctoria, a new genus which, however, is not technically described. 

 He states that the plant is known in Tamaulipas as " palo amarillo," and is 

 used by the Indians to dye deerskins and cotton goods.

 haematocarpus (Wooton) Heller." This and 0. fremontii are not very sharply- 

 differentiated. It seems better to the present writer to refer all the Mexican
