XI. Some Observations on the natural Family of Plants called 
CowrosiTx. By Robert Brown, Esq. F.R.S. Libr. L.S. 
Read Feb. 6 and 20, 1816. 
Tux class Syngenesia of the Linnean artificial system, as at pre- 
sent limited, constitutes a family strictly natural, and by far the 
most extensive in the vegetable kingdom. It is also, with the ex- 
ception of Grasses only, the most generally diffused, and is almost 
equally remarkable with that order, for the great apparent unifor- 
mity in the structure of its essential parts of fructification. 
This class of plants, for which I retain the established name 
Composit, in preference to any of those recently proposed, 
has lately become the subject of a minute and accurate exami- 
nation by Mons. Henri Cassini ; two of whose Memoirs on the 
Style and Stamina of the class, alread y published in the Journal 
de Physique*, are in my opinion models for botanical investiga- . 
tion. ! t Mp t Lu c rS 
A few years before the publication of M. Cassini's Memoirs on 
Compositæ I was induced to examine a considerable part of this 
extensive family, chiefly with a view to the more accurate deter- 
mination of the New Holland plants belonging to it. 
My principal object in the present paper is to communicate such 
general observations, the results of this investigation, as either have 
not yet been published by M. Cassini, or respecting which I consi- 
der myself to have anticipated that author in my General Remarks
