Ruellia Sigs gt is Brazilian, and was introduced by Messrs. 
Jacob-Makoy of Liége in 1875. The plant which furnished the 
material for the figure was received from the Jardin des Plantes, 
Paris, in 1903. Through rather insignificant im its flowers it has 
decorative leaves, and is suitable as a trailer or basket-plant for

for a future occasion 
A further and complete report on the subject has now been 
issued.* The geological and botanical descriptions given in the 
previous adonut are extended, and form part i of the present 
treatise, whilst dune-reelamation forms the subject of part ii. 
It is pointed out by Dr. Cockayne that the final object of

that for fixing drifting sand it cannot be beaten. Where there is 
no drift, or where there is a well fixed marram-area to windward, 
the tree lupin (Lupinus pile is highly Keoomenentes for use
