cuneate at the base, which probably belong to a fourth species of Pseudo'eugenia , 

 The flower-buds of this, which measure less than *! in. in length, are borne in pairs 

 below the leaves. 



10. Barringtonia, Forst. 

 Trees. Leaves alternate, crowded towards the ends of the branches, 

 entire or sliglitly crenate- serrate, pinnate-nerved, not dotted. Flowers 

 in elongated terminal and lateral racemes, or in interrupted spikes ; 

 bracts small, deciduous. Calyx-tuhe ovoid or turbinate, scarcely pro- 

 duced above the ovary ; lobes 2-4, valvate, or 3-5, imbricate. Petals 4 

 rarely 5, much imbricate, somewhat adnate at the base to the staminal 

 tube. Stamens numerous, in several series, connate into a short tube at 

 the base ; filaments filiform, long, all bearing anthers. Ovary inferior, 

 2-4-celled, crowned by an annular disc ; style long, filiform, simple, 

 stigma small ; ovules 2-8 in each cell, pendulous. Fruit fibrous or 

 somewhat berried, globose, ellipsoid or quadrangular, crowned by the 

 calyx, by abortion 1-seeded. Seed ovoid or ellipsoid, without albumen ; 

 embryo large, exhibiting two layers, cotyledons nearly obsolete. 

 DiSTRiB. — Species 25 ; in tropical Asia, Africa, Australia and Polynesia, 

 often near the sea.

long; fruit ovoid or elliptic, not angled or only 



slightly so; rachis much thickened in fruit ... 



Flower-bads just before expansion more than '25 



in. long ; fruit oblong, 4-angled. 

 Main-nerves of leaves 6 or 7 pairs ; fruit 3 in. 

 long ; rachis of spike thickening slightly in fruit 

 Main-nerves of leaves 9 to 12 pairs ; fruit glab-
