Upon tbc same sheet in Sir Wm. Hooker^s herbarium I find 



four specimens of Drege^s collection, all fragments and very bare 



of leaves ; two of these agree with the figure of Thunberg's 



L. tetrandrum ; the others, evidently younger branchlets, answer 



> to his L. horridumy the structure of the flowers being exactly 



? alike in both. I cannot perceive, in the copious descriptions of 



these two species by M. Dunal above quoted, anything that can 

 constitute valid differential characters; we may therefore con- 

 sider them as identical, as Sprengel long ago determined {Syst. 

 i. 700). The older leaves are fleshy, 3 lines long and ^ line 

 - broad; the younger leaves are obovate, 2 lines long : in Dr. Har- 

 vey's specimen the leaves are obovate, spathulate, 7 lines long, 

 2^ lines broad; the peduncle is 1^ line, the calyx 1 line, the 

 tube of the corolla 3 lines, the segments of its border ^ or | line 

 Jong*.
