It is already mentioned in the Introduction that the fpecies which I pub- 

 lished with the name of atro-rubeffcens is Hudfon's C. nigra.

The neareft affinity of this fpecies is with C. b^ffffohles, from which it 

 may however be readily diftinguiihed by its more diffufe and irregular 

 ramifications. The ultimate ramuli are tufted as in that fpecies, but they 

 are lefs numerous, by far more flender, and more repeatedly dichotomous. 

 Mr. Borrer who has attentively ftudied tins plant whilft frefh from its 

 place of growth, in which ftate alone thefe flender ultimate ramuli can be 

 examined with much advantage, informs me, " that they are not compofed, 

 like the other parts of the plant, of feveral parallel tubes, but are fimply 

 tubular, and fpurioufly jointed (uiriculis matrkelibusj, the length of the 

 joints many times exceeding the diameter." Mr. Borrer alio fays, but 

 which I have not myfelf obferved, that fimilar fibres occafionally occur in 

 other fpecies of this feclion which are ufually without them, and therefore 

 queries whether they may not pofiToly be a paraGtical production. The 

 capfulcs rcfemble thofe of C. b\£Vnlcs, except that they are m itly r.iifed on 

 fhort fruit (talks. For the flcetch of this fpecies at pl.:te G, I am indebted 

 to - Mr. Hooker; it reprefents a branch magnified .;, and alfo the joints c, 

 the lower part of the filament magnified 3.
