ADDITIONS TO FLORA OF PALESTINE. 163 



CYPERACE^. 



Cyperus elcusinoides, Kunth. Afghanistan; tropical Africa; India 

 and Australia. Ghor es Safieh. 



N.B. — Several tropical grasses occur in the Gh6r, but, like the 

 majority of the Compositae, they are too widespread to be illustrative. 



The following is a list of species obtained by me in Palestine (includ- 

 ing Petra and Mount Hor), which are additions to its flora as given 

 by Canon Tristram. Except where otherwise stated, the species have 

 been determined by Mr. Oliver.
