Mr. Brown’s Observations on the 
I propose to name this genus in honour of M. Henri Cassini, 
whose Avell conducted investigation of Composite 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 Calea spectabilis of Labillardiere, a plant cor¬ 
responding with it in character, but differing very much in habit 
from all the other species. 
Cassinia. 
Caleae sp. Labillardiere. 
Involucrum imbricatum, scariosum, pauciflorum. Receptaculum : 
paleis distinctis, squamis intimis involucri subsimilibus. Flosculi 
tubulosi, vel omnes hermaphroditi vel paucissimi feminei an- 
gustiores in ambitu. Anthera (inclusae) basi bisetae. Stigmata 
apice obtuso subtruncato hispidulo. Pappus pilosus v. penicil¬ 
latus, persistens. 
Frutices. Folia sparsa , sapius angustata , 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. 
j" Involucrum radiatum (squamis intimis apice patulis). 
1. C. leptophylla, foliis lineari-lingulatis subter ramulisque inca- 
nis, cor 3 r mbis terminalibus, involucris turbinatis. 
Calea leptophylla. Forst. Prodr. n. 287. Willd. Sp. PL iii. 
p. 1796. Persoon Syn. ii. p. 406. Poiret Encycl. Suppl. ii.
