The Desert plants, about one hundred and fifty in number, constitute all that is botanically inter- 

 esting in the Egyptian flora. The Desert tribe of Zygophyltacea being unusual in variety, while the 

 presence of Xeitratfa and s[>incscent Cntciferce is very striking. But of strictly Egyptian features, 

 the most characteristic seem an unusual development of Resedacccr, and especially of Salsolacece, 

 the latter with plants resembling them in sensible properties everywhere dominant 



The river-flat green and grassy is altogether European, the indigenous plants nearly all occur- 

 ring on the opposite side of the Mediterranean : and this continues even within the Tropics, the land- 

 scape as far as the First cataract hardly presenting a distinguishable Tropical feature.

 Mediterranean, also certain Greek and Syrian species occasionally found within reach of the sea air 

 on the facing upland.
