* Flowerbuds obloiig, 2—3 times as long as broad (includiiigthe turbinate 

 base of the calyx). Calyx-tube ribbed, segments in flower distinctly short- 

 cr than the rest of the cnlyx, their inner side red. Pétais always présent, 

 very inconspicuoiis, stril<ingiy resembling tlie filaments, narrowly linear-fili- 

 form. 13—20 inM long, '/a — 1 mM broad, whitc or partly red. Filaments 

 white. Ovary 14— 18-celled. Tube of fruiting calyx conspicuously turbinate, 

 15—20 mM high. segments entirely reflexed. Ripe berry + 4 cM broad, 

 + 3 cM high. Uitimate branchlets biuntly quadrangular, leaves obovate or 

 oval, cuneate at the base, broadly rounded at the top, often emarginate, 

 50-125 mM long, 30—90 mM broad. Tree. 3-15 M high. Along the 

 sea-shore and at the mouth of tidal rivers. also in shallow parts 

 of rather calm seas. Prefers sait water and a hard, not too muddy soil. 

 Often on corai-reefs. (S- e v e ii i a B 1. ) S. alba Smith. 



** Flowerbuds broadiy oval, much less than twice as long as broad- 

 Calyxsegments in flower as long as or slightly longer than the rest of 

 the calyx. Petals either dari< red or entirely wanting. Tube of fruiting 

 calyx flat or shallowly cup-shaped. segments spreading or ascending, 

 not reflexed. Trtes which prefer a muddy soil in the less sait parts 

 of mangrove-forests. 



t Petals linear-lanceolate, dark red, 17 — 35 mM long, l',2— 3 mM 

 broad. Calyx smooth. in flower 30—45 mM high. tube not or hardly 

 ribbed, inner side of segments greenish white or yellow. Ovary 

 16— 21-celled. Segments of fruiting calyx subhorizontally spreading. 

 Berry 50—75 mM broad, 30— 40 mM high. acid. Leaves elliptic, oblong 

 or oval-obovate, cuneate at the base, blunt or rounded at the top, 

 50-1 10 mM long, 20-50 mM broad. Tree, 5,00-15,00 M higii. S. acida L. fil. 



tt Petals entirely wanting. Calyx veriuculose, in flower 26— 30 mM 

 high, tube distinctly ribbed, inner side of segments strongly tinged with red. 

 Ovary 13— 15-celled. Segments of fruiting calyx ascending, appressed 

 against the fruit. Berry 30— 45 mA^ broad, ± 25 mM high. Leaves broadly 

 ovate or broadiy oval, rounded or subcordate at the base, broadly rounded 

 at the top, 50—100 niM long, 45—90 mM broad. Small tree. 2,00—5,00 M 

 liigh S. ovata Backer. 



S. alba Smith and S. acida L. fil. vvere both included in the Liiinaean 

 name Rhizophora caseolaris L. Hence the name Sonneratia caseolaris {L) 

 Engler cannot be retained for either of theni.
