This forms a very distinct species, with rugous knotty branches 

 and naked spines, 2 lines in length, springing out of the nodes : 

 there are five to teu leaves in each fascicle, 4 or 5 lines long, and 

 \ line broad : the slender peduncle measures 4 lines ; the some- 

 what tubular calyx is 1^ line long, half cleft into four narrow, 

 acute, equal segments, each separated by a rounded sinus ; the 

 tube of the corolla is 5 lines long, 1^ line in diameter at its 

 broadest part, the lobes of the border being only | line; the 

 filaments are inserted into the tube at a distance of a quarter of 

 its length from the bottom, and are pilose at base for one-fourth 

 of their length*. •

This very distinct plant bears greatly the aspect of several 

 species of the genus Alona, and oiPhrodus^ which I have before 

 described [huj. vol p. 24), all collected in the same neighbour- 

 hood, and at the s^e time, by Mr. Bridges, as their respective 

 numbers will show. The branches and branchlets are very knotty 

 and intricately crossed; the prominent, nodose axils, scarcely
