The fruit of this variety is unknown ; but the scanty material, so far as it goes, 

 appears to show that the plant is merely an apetalous form of 8. acida with leaves 

 more obovate than is usual in that species. I have therefore reduced it to a form 

 of the latter. Blume described other three species of Sonneratia with petals, 

 viz., 8. obovata, 8. evenia, and S. lanceolata separating them chiefly by characters 

 taken from the shapes of the leaves. But in this genus the form of the leaf is very 

 variable, and I doubt whether these three species are more than forms of 8. acida. 

 8. Pagapat, Blanco, and 8. ovalis, Korth. are probably also forms of it. 



2. Sonneratia alba, Smith in Rees Cyclop. XXXIII, jNo. 2. A small 

 tree 10-15 feet high ; young branches rather terete. Leaves obovate or 

 obovate-reniform, decurrent on the short petiole, blunt or retuse, 2-4 in. 

 long and nearly as broad, petiole '125-*25 in. Flower-buds narrowly 

 ellipsoid, tapering to each end, very slightly ridged; the fully developed 

 calyx sharply angled ; its lobes 6-8, oblong-lanceolate, acute. Petals none. 

 Flowers about the size of those of S. acida, usually 2 or 3 together. 

 Capsule broadly obconic, ribbed, 1 in. or more in diam. at the apex.

Herbs, rarely undershrubs, sometimes aquatic. Leaves opposite or 

 alternate, entire or toothed, undivided (in Trapa the submerged leaves 

 pinnatipartite), exstipulate. Flowers hermaphrodite, mostly axillary
