Mediterranean-Region. (M.) including under this term the 
Coast region from Marmarica to El-‘Arish, the sandy foreshore bet- 
ween the alluvial soil and the Sea. This region is divided into 
two parts, an western (M. ma.) marmari¢ subregion, which extends 
from Marmarica to Abukir, and an eastern pelusiac subregion 
(M. p.) which extends from Abukir to El-‘Arish. 
Nile-Delta-Region. (N.) comprises the cultivable land. This 
region is divided into four subregions. These are: 
1. The Nile-Delta (N. d.) which is 100 miles broad at its Medi- 
terranean base, but narrows to about 10 miles at its head 
below Cairo. 
2. The Fayim (N. f.) the quasi-oasis, on the left bank of the 
river, which measures about 30 miles from North to South, 
and 40 miles from Hast to West. 
3. The narrower alluvial Nile-Valley (N. v.) the alluvial soil 
from Cairo to Aswan, called by the Arabs Er-Rif. 
4. The narrower rocky Nile-Valley (N. v. mer.) not alluvial but 
rocky ground. 3

1. Siwa. 
2. Little Oasis. 
3. Farafra.

Desert Region. (D.) This region is divided into four subregions; 
these are: 
1. W. of the Nile. 1. Libyan Desert. (D. 1.) 
2. E. of the Nile. 2. Isthmie Desert. (D. i.) — Extends from 
the Mediterranean-Seashores and the eastern limits of Egypt 
to the Wady Tumilat. 
3. Northern Arabian-Desert. (D. a. sept.). — Extends from 
Wady Tumilat to the Kene-Qoseyr-Road. 
4. Southern Arabian-Desert. (D. a. mer.). — Hxtends from the 
Kene-Qoseyr road to the Southern limits of Egypt. 
Red-Sea-Region. (R.) — The sea-shores along the Red-Sea. 
With these remarks on the general botany of Egypt, we will 
proceed to the consideration of each of the five regions above in- 
dicaded.

From whicheyer side it is approached the coast of Egypt is so 
exceedingly low that the highest parts only begin to be seen at the
