REMARKS ON TABLE OF FLORA OF SINAL 127 



large a space would be occupied by contractions representing accuracy in 

 enumerating the lists of stations given by Boissier. I have therefore 

 only indicated the tendency of the distribution of the species. Thus E, 

 signifies that the species reaches Persia, Beloochistan, Scinde, Afghanistan, 

 or even India on the East ; W. stands for North Africa, Canaries or Cape 

 Verdes on the West ; and T. intimates that the plant is found either in or 

 on the edge of the Tropics, chiefly in Nubia, Abyssinia and Arabia, 

 Broadly speaking, E. generally stands for Persia and Beluchistan, and W. 

 for North-west Africa and islands. 



The third column includes Mediterranean species. I have here again 

 endeavoured to tell something of the range of the plant by a system of 

 letters. Thus an asterisk stands for typical Mediterranean ; L. for local 

 Mediterranean, confined to a very limited portion of its coast ; E. shows 

 that the species has a further wide range eastwards to Persia ; and W. that 

 the plant inhabits the western countries of the Mediterranean, sometimes 

 even reaching the Canaries, and thus illustrating the transition between 

 the Mediterranean and the Desert floras. The transition on the tropical 

 side is, however, more obvious. 



The fourth column is the most difficult and uncertain one to deal with. 

 The elevation at which the plant appears on Sinai itself has been taken as 

 a first guide, but many Sinaitic species have a wide, vertical distribution, 

 and those which have, will be found more often to be of a Mesopotamian 

 or Syrian desert character, than either Mediterranean, Montane or 

 Plateaux. Most of the Plateaux or Mountain plants of Sinai, which are 

 properly so classed, reappear in the elevated parts of Persia (E.), a few in 

 Songaria, Turkestan and the Caucasus (N.E.), some more in the moun- 

 tains of Asia Minor, Taurus and the Lebanon range (N.), a very small 

 number in the North-western Mediterranean mountains (N.W.),']and the 

 Western Algeria or Morocco Plateaux (W.), and two or three in the 

 southern mountains of Nubia and Abyssinia (S.). 



The last column is reserved for species too widespread to fall in line 

 elsewhere, Tp, signifies that they are chiefly of the temperate region of 

 the Eastern Hemisphere ; W^m. is placed after plants of warm or 

 tropical countries, widely spread in the Old World ; while W. W. gives a 

 further ' world-wide' range to the Western Hemisphere,
