 rainosa, ramis lateralibus densissinie corymbosis, rainulis dicho- 

 tomis subdivaricato-patentibus, terminalibus furcatis acutis. 



Hab. in sinu tabulari ad Caput Bonse Spei (Hb. Crouan). - 

 Exigua ramificationis differentia excepta, cum priori in omnibus 

 convcnit. Rami primarii magis in latus dejecti, circa caulem pri- 

 marium paniculatim dispositi, ramulis densissimis onusti et fere 

 corymbosi. Ramuli corymborum subdivaricati decompositi, termi- 

 nales a basi latiore acuminati. Color fere lateritius. Substantia 

 planta^ exsiccatie cartilaginea; madefacta fragilissima et mox soluta. 

 Structura omnino pra3cedentis. Fructus ignoti.
