SOME PLANTS FROM JEBKL MAURA, PAUFl'K 4/ 



to the present time. The greater part of it, according to Capt. Lynes's 

 observations, has a mean altitude of 8000 feet, with peaks rising to 

 10,000 feet or more. No altitudes of anything like the same im- 

 portance are found nearer than the Tibesti Mountains in the Sahara 

 (600 miles N.W.), the Abyssinian Plateau (700 miles E. by S.), the 

 Great Equatorial Mountains (900 miles S.S.E.), and the Cameroons 

 and Nigerian Mountains (900 miles W. by S.). Jebel Marra thus 

 stands in a position of splendid isolation, and detailed information as 

 to its fauna and flora cannot fail to be of very high interest. 



The vegetation of the province as a whole " varies from pure 

 desert in the North to rather rich park-land (Savannah) in the South." 

 The greater part of the- area is covered with "typical North Sudan 

 bush and scrub." The low hills are either quite arid, or covered with 

 the saine vegetation as the plain. But Jebel Marra is " quite dif- 

 ferent from anything else in the Province. These are well-marked 

 vegetal zones, and the upper zone, from about 8000 feet upwards 

 contains many temperate plants." 



The following list includes only those species which were found in 

 the mountainous district, but a considerable number of plants were 

 also collected on the plains. A fortnight was spent at Kallokitting 

 (alt. 4000 ft.), which Captain Lynes used as his base, and about 

 10 days on the mountain itself. The list, so far as it goes, indicates 

 the presence of a composite flora in which North Temperate, Medi- 

 terranean, Abyssinian, Sudanese, and widespread Tropical types are 

 all represented : — 



Adiantum Capillus-Veneris L. 7300 ft. (very widely spread). —
