APPENDIX. No. V. 
Observations, Systematical and Geographical, on Professor CHRisTIAN 
Smitu’s Collection of Plants from the Vicinity of the River Congo, by 
Rozerr Brown, F. B.S. 
Tue Herbarium formed by the late Professor Smith and his assistant Mr. 
Dayid Lockhart, on the banks of the Congo, was, on its arrival in England, 
placed at the disposal of Sir Joseph Banks; under whose inspection it has 
been arranged; the more remarkable species have been determined; and the 
whole collection has been so far examined as the very limited time which could 
be devoted to this object allowed. 
In the following pages will be found the more general results only of this 
examination; descriptions of the new genera and species being reserved for a 
future publication. 
In communicating these results I shall follow nearly the same plan as that 
adopted in the Botanical Appendix to Captain Flinders’s Voyage to Terra 
Australis: 
Ist. Stating what relates to the three Primary Divisions of Plants. ~~ 
2dly. Proceeding to notice whatever appears most remarkable in the several 
Natural Orders of which the collection consists; and, 
3dly. Concluding with a general comparison of the vegetation on the line of 
the river Congo, with that of other equinoctial countries. 
I. The number of species in the herbarium somewhat exceeds 600; the 
specimens of several of which are, indeed, imperfect ; but they are all referable 
with certainty to the primary divisions, and, with very few exceptions, to’ the 
natural orders to which they belong. 
Of the Primary Divisions, the Dicotyledonous plants amount to 460 
The Monocotyledonous to - = = = 113 
And of the Acotyledonous, in which Ferns are included, there are 
only - - - - - 33 species. 
It.is a necessary preliminary, with reference especially to the first part of my 
subject, to determine whether this herbarium, which was collected in a period 
not exceeding two months, and in a season somewhat unfavourable, can warrant
