A very leafy species, remarkable for its conspicuous, cottony, 

 knotty axils, which are from \ to ^ inch apart : the leaves, four 

 to six in each fascicle, are 8 to 10 lines long, 1^ to 2 lines broad : 

 the flowers are about the size and shape of those of the preceding 

 species; the peduncle, equal in length to the calyx, is 1 line 

 long ; the corolla is 3 lines long ; the segments of the border 

 are { line long and broad*.

This very distinct species, fully described by Dr. Sendtner 

 and M. Dunal, is remarkable for its approximated large leaves 

 and copious fascicles of flowers. It is a small tree, growing 

 commonly along the banks of the river San Francisco, about 

 eighty miles from its mouth, where it is called Espinha, though 

 it is generally unarmed. Its branches are much used by the 

 natives for making fences. A variety, which may be called 

 obovatum, on account of its more ovate and obtuse leaves, exists 

 in Sir William Hooker^s herbarium, collected by Mr. Gardner on 

 the llha de San Pedro, an island near the mouth of the river 

 San Francisco f.
