Synopsis of the genera. 



1 Ta'marix. Calyx 4- 5 -parted. Petals 4-5. Stamens 4-5. 

 Stigmas 3, long, glandular and oblique at the apex. Seed in- 

 serted at the base of the valves, or almost in the centre of the 



form, 1-seeded, covered with fibrous aril. Embryo inverted and capsule ; hairs on seeds simple. 



curved in the albumen. — A tree, with opposite, oboyate, obtuse, 

 obsoletely-denticulated, coriaceous, glabrous leaves, which are 

 full of fine parallel veins. Corymbs axillary, short. Flowers 

 small. The seeds and fruit of this genus disagree entirely with 

 tne other genera of this order.
