THE FLORA OF ADEN.

vegetation as might be inferred from this description. Many of the 

 valleys are thickly studded with small trees and shrubs, producing 

 beautiful flowers, and it is no uncommon circumstance for the inha- 

 bitants of Sheikh Othman (a village distant about 4 miles from the 

 British frontier) to send their goats and camels to find pasturage 

 amongst the valleys on the west side of the peninsula, when none is 

 procurable in their own district. 1 



We must, nevertheless, call the flora of Aden a very poor one if 

 we compare the total of species with the considerable area they occupy. 

 In our list we gave the names of 196 plants, which are representatives 

 of 47 orders and 114 genera. The accompanying table will show the 

 small proportion of species to the number of genera and natural orders.
