2. Diospyros blepharophylla Standi. Contr. U. S. Nat. Herb. 18: 119. 1916. 

 Diospijros ciliata A. DC. in DC. Prodr. 8 : 229. 1844. Not D. ciliata Raf. 1836. 

 The type is said to iiave come from southern Mexico. 



Petioles 1 cm. long; leaves ovate-elliptic, 4 to 7 cm. long, obtuse at base, 

 membranaceous ; flowers 4-parted. 



3. Diospyros conzattii Standi. Journ. Washington Acad. Sci. 12: 399. 1922. 

 Type from Cafetal San Rafael, Cerro Espino, Distrito de Pochutla, Oaxaca, 



altitude 1,000 meters. 



Tree, 10 meters high ; leaves sliort-petiolate, ovate-oblong or lance-oblong, 

 5 to 9.5 cm. long, acuminate; calyx lobes linear-lanceolate, 15 to 18 mm. long, 

 long-attenuate ; fruit depressed-globose, about 4 cm. in diameter, green, the 

 flesh black ; seeds 5 to 10. " Zapote negro months." 



The fruit is said to be of excellent flavor, and Professor Conzatti states 

 that it is superior to any of the native Mexican fruits, with the possible ex- 

 ception of the chicozapote. 



4. Diospyros palmeri Eastw. Proc. Amer. Acad. 44: 604. 1909. 

 Tamaulipas and San Luis PotosI ; type from San Dieguito, San Luis Potosi. 

 Shrub or small tree, 2.5 to 4.5 meters high, the trunk 10 to 15 cm. in diameter, 



the bark scaly; leaves oblong-obovate or elliptic-oblong, 2.5 to 5.5 cm. long; 

 flowers 5-parted, glabrous ; fruit black, 2.5 to 3 cm. in diameter. " Chapote," 

 "zapote negro" (Tamaulipas). 



5. Diospyros anisandra Blake, Proc. Biol. Soc. Washington 34: 44. 1921, 

 Type from forests of Suitun, Yucatrm. 



Shrub, 3 meters high ; leaves obovate, 2.5 to 4.5 cm. long, retuse at apex, 

 shining above, glabrous except for a few hairs at base of blade on upper side ; 

 staminate corolla yellow, 14 mm. long, glabrous. 



6. Diospyros texana Scheele, Linnaea 22: 145 1849. 

 Brayodendron texanum Small, Bulb Torrey Club 28: 356. 1901. 

 Coahuila, Nuevo Leon, and Tamaulipas. Western Texas. 



Shrub or tree, sometimes 16 meters high, with a trunk 60 cm. in diameter ; 

 bark thin, smooth, light reddish gray, the outer layers peeling ofC ; leaves nearly 

 sessile, broadly obovate or oblong-obovate, 1 to 4 cm. long, rounded or emar- 

 ginate at apex ; corolla sericeous, 8 to 12 mm. long ; fruit black, about 2 cm. in 

 diameter, the pulp sweet, dark, containing 3 to 8 seeds ; wood hard, compact, 

 nearly black, its specific gravity about 0.85. "Chapote" (Tamaulipas, Texas) ; 

 '* chapote prieto " (Nuevo Leon). 



The wood is susceptible of a high polish. It has been used for turning and 

 for making tool handles, and in England it is said to have been used as a sub- 

 stitute for boxwood, in making engravings. The fruit is astringent when 

 green but sweet when fully ripe. It leaves an indelible black stain upon every- 

 thing with which it comes in contact, and is employed locally for dyeing sheep 

 and goat skins. 



Diospyros cuneifolia Hiern,^ does not appear distinguishable from the de- 

 scription. It is said to come from Mexico. The writer has seen no material of 

 D. texana californica T. S. Brandeg.,* which was described from Baja Cali- 

 fornia. It may be a plant closely related to D. texana, but it seems more prob- 

 able that it is a relative of D. sonorae, unless it should be found to be Maba 

 intricata. Specimens of the last have been reported from Baja California as 

 Brayodendron texanum.
