Dr. Clos, on the authority of M. Gay, describes this as a 

 low-growing shrub, about 2 feet high, with intricately twisted 

 branches, which are armed with numerous simple spines, half an 

 inch in length, and a similar distance apart. They are often 

 leafless ; the extremely deciduous leaves are very small, almost 

 entire, or crenulated on their margin ; they are linear-oblong, 

 and 1 to 3 lines in length. The small white flowers, which be- 

 come dark in drying, are 4-merous, and scarcely exceed a line 

 in length, including their very short peduncle, and half a line 

 in diameter. The stamens are hidden within the short cucul- 

 late petals, the anthers, after dehiscence, becoming peltate, as in 

 the other species of the genus. It is known by its vernacular 

 name of Ahrojo, which in Spanish signifies a bramble. These 

 characters are all quite in accordance with those of Trevoa-\.
