Radix callus minimus furcnlos protruclens unde nova* fiunt 

 plants — From folitaria vel numerofa, comprefla, purpurafcens, 

 3 — 4imcialis,craflitie fili emporetici minoris, ramofiffima — Ramifxpl- 

 us oppofiti, ram fparfi, bafi attenuati — Ramuli fefiiles, fed brevifli- 

 mi, erectiufculi, apicibus incraflatis obtufiffimis truncatis — Fruftifi- 

 atfloy tubercula riilnutajn ramulorum apicibus, necnon ad ramorum 

 latera fita, atro- purpurea. 



This fpecies, which appears to have been firft defcribed by the 

 author of the Flora Angiica, cannot be confounded with any in this 

 divifion, unlefs the varieties (i and y of corneus, from both which it 

 is eafily to be diftinguithed by being, though cartilagineous, of a 

 more tender fubftance ; by having the branches attenuated at the 

 bafe ; and, notwith (landing they are comprefTed, not fo completely 

 flattened ; by the fomewhat erect growth of the ramuli ; and more 

 particularly by having the branches truncated at the end, and by 

 the fructification : this confifts of minute nearly black tubercles, 

 fituated in the dilated terminations of the ramuli, as defcribed by 

 Mr. Hudfon ; and alfo, as we have obferved not unfrequently on 

 our fpecimens, on the fides of the larger as well as the fmaller 

 branches. The primary frond is continued throughout, the branches 

 are fhort near the bafe, longer in the middle, and very lliort towards 

 the fummit, giving the whole an ovate form. — The principal 

 branches are clothed with fecondary ones growing in the fame 

 manner, and thefe with the extreme ramuli; nor have we obferved 

 it farther divided.
