XC. GUNNERACE^E. 



The affinities of Haloragece with Onagrariea will be indicated in the description of the latter. 1 They 

 are near Trapea, which were formerly placed in the same family, and which only differ in their hemi- 

 spherical stigma and exalbuminous embryo. They also approach Combrctacece, which are separated by 

 their ovary (which is always 1-celled and 2-4-6-ovuled), their simple style, drupaceous fruit, and exalbu- 

 minous embryo. 



Haloragetz are rare in the tropics ; they are found most abundantly in temperate and cold countries 

 (Hippuris), especially beyond the tropic of Capricorn ; Haloragis is only found in Australia and the 

 neighbouring islands. They are of no use to man.
