7. Acacia hindsii * Benth. Lond. Journ. Bot. 1 : 504. 1842. 



Acacia smaloensis Safford, Journ. Washington Acad. Sci. 4: 365. 1914. 



Acacia tepicana Safford, Journ. Washington Acad. Sci. 4: 366. 1914. 



Sinaloa to Chiapas ; type from Manzanillo, Colima. 



Shrub or small tree; spines mostly 3 to 5 cm. long, brown, gray, or black, 

 usually much compressed and often 2 cm. wide at base; leaflets 3 to 8 mm. 

 long; flowers yellow, the spikes slender, 3 to 5 cm. long; fruit usually 4 to 6 

 cm. long, brown or blackish, beaked, more or less compressed. " Guisache 

 corteno," " cornezuelo " (MichoacS.n, Guerrero); " carretadera " (Sinaloa). 



The spines vary greatly in form and color in this and related species, 

 so that it is doubtful whether they afford characters of any value for the 

 separation of species. The bark is employed in Sinaloa as a remedy for 

 scorpion stings. 



8. Acacia globulifera Safford, Journ. Washington Acad. Sci. 4: 360. 1914. 

 Type from Tsilam, Yucatan. 



Spines 3 to 4 cm. long, terete or slightly compressed, pale; leaflets 3 to 4 

 mm. long; flowers yellow, in small heads. 



A. chiapensis Safford ' is probably the same species, but since it was described 

 from fruiting specimens and A. globulifera from specimens with flowers, it 

 is impossible to be certain. A. chiapensis was based on specimens collected near 

 San Fernandino, Chiapas. It is a shrub or small tree, 3 to 5 meters high. 



9. Acacia nelsonii Safford, Journ. Washington Acad. Sci. 4: 363. 1914. 

 Vicinity of the type locality, Acapulco, Guerrero.

• Richard Brinsley Hinds was an oflicer of H. M. S. Sulphur, a British ship 

 which was engaged from 1836 to 1842 in surveying the western coast of America, 

 the field of operations extending from Peru to Alaska. The botanical collections 

 were obtained by Hinds, Dr. Sinclair, an oflicer of the ship, and George Barclay, 

 a gardener from Kew. Plants were collected in Mexico about San Bias and 

 Tepic, and at Cape San Lucas and Magdalena Bay, Baja California. They were 

 reported upon by Hinds, the new species being described by Bentham.
