The Flora of Singapore. 
BY H. N. REY. 
Introduction. The island of Singapore with the small 
islands of Pulau Ubin d Pulau Tekong in the Johore strait 
and a few smaller ones lying within English waters form the 
area the flora of which is enumerated in this paper. The whole 
is little more than 200 square miles in extent and consists of 
undulating country, the highest hill being Bukit Timah with an 
altitude of 500 feet above sea level. The Geology of the ees 
was the et of a paper by Mr. J. R. Logan (Journ. 
Beng. xvi. p. 519, published in 1846), but ейн: dn 
much ub it, mistaking sedimentary rocks for vol- 
canic ones. The bigger hills, Bukit Timah, Bukit Mandai, and 
Tanjong Gol, are c sed of a grey granite, which crops out 
again near Bajau, aie, owen and Pulau Ubin. The rest of the 
island is covered with sedimentary deposits of clays, gravels, 
and sands, often very ferruginous and permeated with bands of 
clay-ironstone, very much resembling that of some of the Weal- 
den bedsin Kent. This clay iron-stone has unfortunately received 
the name of Laterite here, a name properly applied to soils baked 
by a lava-flow, or other volcanic heat. These sedimentary rocks 
have never produced any fossils except some obscure ngah с 
vegetable remains. They appear to have been derived f 
disintegrated and decomposed granite, the ironstone nsns 
being formed in many cases at a much later date. No borings 
of any depth having been made it is чайчы to say how deep 
these strata are, but it is probable that they are of very к 
thickness and comparatively pup Н as appears to the case 
point. But soon after it was acquired, a great deal of this forest
