58 DR. TIERNEY AITCHISON ON THE FLORA 
Amongst the hills here and there we have springs of fresh 
water running through the valleys, which, as long as they run 
upon a stratum above the salt, give rise to a. great luxuriance of 
vegetation. In these valleys we meet with much fertile soil, 
and have, for the first time, the cultivation of the Poppy to 
some extent. Rhus integerrima, producing good timber, with 
Bombax heptaphyllum, and in some localities the Mulberry and 
Acacia modesta, grow in great luxuriance ; the Vine also is to be 
met with naturalized. In the fields of the tableland Salvia Moor- 
eroftiana is found everywhere, besides Edwardsia Hydaspica, 
Gypsophila Vaccaria, Lithospermum arvense, Lepidium, &c. 
Mount Tilla, the most westerly of the Ratian Range, has a 
more wooded appearance than any part of the Salt Range; for the 
latter is chiefly wooded in its valleys, whereas Mount Tilla, from 
apparently its greater moisture, is wooded all over, chiefly, how- 
ever, where the altitude rises above 2000 feet, with trees of 
Bombax, Rhus, Moringa, Olea, Acacia rubicaulis, Rottlera, Kydia, 
Cordia, Celtis, &c. Besides these we have the following, depen- 
dent upon the altitude obtained, viz. Galium, Geranium, Convol- 
vulus, Cheilanthes, and Asplenium. In addition to these we have 
Punica Granatum, naturalized, if not indigenous, and a solitary 
specimen of Pinus longifolia, introduced about thirty years ago. 
Phenix sylvestris covers the hill on its western aspect from its 
base to its summit. 
In conclusion, I beg to return my most sincere thanks to Dr. 
Thomas Thomson for the care and trouble he took in my behalf 
in naming and correcting my collection of plants, and to Dr. Joseph 
Dalton Hooker for the kind and very liberal manner in which he 
permitted me to make use of the Kew Herbarium and Library.
