126 M7\ Brown's Observations on the 



I propose to name this genus in honour of M. Henri Cassini, 

 whose well conducted investigation of Compositse has already 

 thrown much light on the structure and economy of the more im- 

 portant parts of fructification of this difficult class : and espe- 

 cially of those organs from which the distinguishing characters of 

 Cassinia are here derived. 



I shall add the characters of the species of this genus, which, 

 like Ozothamnus, admits of subdivision into two sections ; and I 

 have appended to it Caleu spectabilis of Labillardiere, a plant cor- 

 responding with it in character, but differing very much in habit 

 from all the other species. 



• C^ASSINIA. 



Galeae sp. Labillardiere. 



Ifivolucrum imbricatum, scariosum, pauciflorum. Receptaculum : 

 paleis distinctis, squamis intiniis involucri subsimilibus. Flosculi 

 tubulosi, vel omnes hermuphroditi vel paucissimi feniinei an- 

 gustiores in ambitu. Anthercs (inclusae) basi bisetae. Stigmata 

 apice obtuso subtruncato hispidulo. Pappus pilosus v. penicil- 

 latus, persistens. 



Frutices. Folia sparsa, scepius angiistata, marginibus recurvis, In- 

 florescentia terminalis, corymbosa rariusve paniculata. Involucra 

 alba nunc cinerea raro aurea ; squamis intimis scepius apice conni- 

 ventibus, nunc patulis et radium brevem obtusum efformantibus. 



■f" Involucritm radiatum (squamis intimis apice patulis). 



1. C. leptophylla, foliis lineari-lingulatis subter ramulisque inca- 

 nis, corymbis terrainalibus, involucris turbinatis.
