phius. In the rivers of Malabar, as well as in the Ganges and 
Erawadi, it grows on slimy banks; while in the Moluccas it is 
found on rocky shores. 
= In his unnatural genus Rhizophora, Linnæus included without 
. distinction both the plants of Rumphius, calling them R. caseo- 
laris; but, for what reason I know not, the Blatti is not quoted 
(Burm. Fl. Ind. 108.).. M. Sonnerat in his Voyage to New Guinea 
gave a figure of this plant, calling it Pagapate, evidently the 
same with the Bagatbat, by which name it is mentioned by Ca- 
melli. The younger Linnzus then became sensible that this 
plant could not be continued as a Rhizophora, and called it 
Sonneratia acida. M. Lamarck divides this into two varieties ; . 
the rubrum of Rumphius, which he considers as the Blatti, and 
- the album of Rumphius, which he makes a second variety : but, 
as I have said, the difference probably consists merely in the 
age of the branch; the young ones in flower being quadrangular, 
while those in fruit are rounded. This also seems to have been 
the opinion of Willdenow (Sp. PI. ii. 999.), who quotes both 
the 73rd and 74th table of Rumphius, without establishing two 
varieties. Gærtner, however (De Sem. i. 379. t. 78. f. 2.), for 
his Aubletia caseolaris cites only the Mangium caseolare album 
(tab. 73.); and neither quotes the Mangium caseolare rubrum of 
Rumphius, nor the Blatti of Rheede. At the time, however, hé 
would not seem to have known the change that had been intro- 
duced by the younger Linneus: and subsequent authors have 
considered (Willd. ubi supr. Enc. Meth. Sup. i. 641. jars 
Aubletia as the Sonneratia acida. 
In Bengal this plant is called Ourchaka, which has nó resem- 
blance to Ambetti, the name used by the Brahmans of Malabar, 
probably from the fruit being used as an acid seasoning, like - 
that of the Mangifera, which they call 4mbo; and this in the
