Read June 21st, 1860. 
THERE are few countries which possess so many new and imperfectly understood genera 
of plants as the Malayan Islands and Western Africa ; and the researches of recent travel- 
lers have added largely to our collections of them. The herbaria of the late Mr. Griffith, 
collected in the districts around Malacca, Singapore, and Mergui ; of the late Mr. Motley, 
in the northern and southern parts of Borneo ; of Mr. Hugh Low, on the same island, and 
especially on the lofty mountain of Kini Balou ; and of Mr. Thomas Lobb, in Sarawak 
and Labuan, contain many obscure tropical forms of plants, together with interesting 
new genera and species of better understood families. In Tropical Africa the researehes of 
the late indefatigable Mr.Barter, on the banks of the Niger river, during Dr. Baikie's expedi- 
tion, have procured the most extensive and perfect collections ever formed in those countries, 
which also contain many singular and interesting unpublished forms. Mr. Barter's sue. 
cessor, Mr. Gustav Mann from Kew, has been no less successful in Fernando Po, where 
he has ascended the Clarence Peak, and procured the first types of a temperate elevation 
that have hitherto been found in West Tropical Africa*. Other unpublished materials 
exist from the Gulf of Guinea, collected at Abeokuta by the late Dr. Irving, R.N. ; 
and still more recently a most valuable and extensive collection of drawings, with ana- 
lyses, of Eastern Tropical African plants have been received from Dr. Kirk, the accom- 
plished and indefatigable companion of Dr. Livingstone; and the collections of that 
gentleman, which are shortly expected in England, will no doubt supply many more novel 
ties of the greatest scientific importance. Prom these and other sources I propose to offer 
to the Linnean Society a series of papers illustrating the most interesting discoveries thej 
contain
