Rhizophora conjugata Ll. Bacauan (Philippines); Bako, 
Bakko, Bakau akit, Bakau akik, 
Bakau minyak (Malay). 
Tropical Asia. 
This is found in nearly the same situations as the preceding, 
but does not push out quite so far. It also grows straighter 
and quicker, often prostrate and with prop-roots from various 
places on the stem. The leaves are narrower and darker than 
in the preceding. It is, however, most easily distinguished by the 
widely spreading calyx-segments which are pale yellow within. 
Both the species of Rhizophora are well characterized by the 
great network of sprangling prop-roots which hold the trunk 
up in the air. The Rdizoplora’s are always found in what may 
be considered the most representative part of the swamp. Where 
the tidal streams penetrate the swamp, these two species are 
to be found on the banks and out into the stream. They form 
fair sized trees, usually not exceeding 10—15 m. in height and 
20 em. in diam., but individual trees are found which reach 
25—30 m. in height and 60 cm. diam. 
Kandeha Rheedii W. et Arn. 
Tropical Asia, from Hindustan to Hong Kon 
Borneo. 
This is usually a rare tree in the mangrove. It is distinct 
in appearance because of the white and star-like form of 
the calyx and the ridged seedling. It also has leaves with 
rounded apices. It is, as yet, but imperfectly known. It is a 
small tree and grows at the edge of tidal streams, usually at 
some distance back from the coast. It is not utilized commer- 
cially, so far as I know. I have seen it only at high tide and 
have not been able to determine the nature of its roots; but, 
{ have classed it tentatively with Bruguiera, as knee-rooted. 
The wood is of only medium hardness and weight, of light 
color and with yellow pith-rays. “Wood used only for fire- 
wood; bark used in Tavoy for dyeing red, probably as a mor- 
dant.” (GamsLr, Manual of Indian Timbers 334). 
It seems to be of rare occurrence in the Malayan region, and
