NOTICIJS OF BOOKS. 223 



I enclose you a Silene for our friend Gay, unknown to me, (annua, 

 foliis linearibus, floribus squalide luteo-fulvis, petalis profunda 2-partitis 

 partitionibus linearibus, corona valde conspicua;) likewise the seeds of 

 a Composita, allied to Cotula suheoronopifoUa (foliis crassis linearibus, 

 floribus eligulalis rufulis, capitulis nutantibus). I found today a single 

 specimen of a Hyacinth, with flowers of the colour of mahogany*, and 

 two of a Scilla^ quite new to me. 



March \2t7i, — The courrier remains till tomorrow. Today I passed 

 through the Palm-wood ; it is narrower than I had been told : I crossed 

 right through it in a good half-hour 3 beyond it I found again the 

 desert like that to the south of Gabes. The plants in flower, besides 

 Gymnocarpum decandriim^ were three HeliantJiemuma^ Linaria Mgyptlaca^ 

 Erodium glaucopliyllum and asplenioides, an Astragalus^ EchiochUon 

 fruticosum^ etc. 



This part of the desert is cut into deep ravines by the winter rains ; 

 their sides are frequently nearly perpendicular, and will probably give 

 shelter and shade shortly to many curious plants. The rest of the 

 desert is flat, with a slight descent towards the sea, above which its 

 general height can scarcely exceed one hundred and fifty feet. xVbout 

 two leagues further I perceived a chain of low mountains ; continuing 

 southward I came upon the cbain of lagoons, out of which the Oued 

 Gabes rises. To my surprise I found nothing near them but Samohis 

 Valerandi; later in the season they will probably give me something 

 better. ^ 



To inspect the whole of my territory I must now make excursions to 

 the north, similar to those I have made to the south.
