account of them in the Pharmaceutical Journal, from which we — 
extract the following :— 
“In the economy of Nature the Mangrove performs a most 
important part, wresting annually fresh portions of the land 
from the dominion of the ocean, and adding them to the 
domain of man. This is effected in a twofold manner: by the 
progressive advance of their roots, and by the aerial germina- 
tion of their seeds, which drop into the water with their roots 
ready prepared to take possession of the mud, in advance of 
their parent stems. The progression by means of the roots is 
effected by fresh roots, which issue from the trunk at some 
distance above the surface of the water, and arching down- 
wards penetrate the mud, establishing themselves as fresh 
plants. Mangrove bogs are certain indicators of a malarious 
locality, inasmuch as they prevent the escape of unhealthy 
miasmata. ” : 
Rheede (Hort. Mal. vi., tt. 33, 34, 35,) figures Bruguiera 
caryophylloides, Rhizophora mucronata, and 
Kandelia Rheedii, and mentions their medicinal use on 
account of the astringency of their juices. All of these plants 
are known as Kandel in Malabar, the Portuguese call them . 
Salgeira, and the Dutch Runboom. They contain abundance 
of tannin, and are used in India by tanners. With salts of 
copper and iron they yield olive-brown, rust and slate-coloured 
tints, and are consequently employed in dyeing.
