THE CARYOPHYLLACEX OF TIBET. 395 
The CanvoprHYLLACE.E of Tibet. By Frederic N. WiLLIAMs, F.L.S. 
[Read 4th June, 1908.) 
THE plants collected in the course of the Military Expedition to Lhassa in 
1903-4, undertaken by the Indian Government, in relation to the Tibet 
Frontier Commission, were stored in the Caleutta Herbarium. It was the 
intention of Col. Prain to issue a Report, which should inelude an account of 
the plants collected on the Expedition together with other small parcels of 
Tibetan plants whieh had been sent during the previous 20 years to the 
Caleutta Herbarium and had lain there unexamined. Оп Col. Prain leaving 
Caleutta to take up his duties at Kew this idea was abandoned, and those 
who had undertaken to examine the material of different families were 
accorded permission to publish the results of their determinations through 
some other source. 
Mr. W. B. Hemsley’s ‘Flora of Tibet? was published in April 1902, in 
this Journal (vol. xxxv.), and therefore ineluded none of the material 
mentioned above. Mr. Hemsley therein enumerates 11 species of Caryo- 
phyllacez. The reason for offering the present paper for publication is that, 
after examination of the further material available, the number of species of 
Caryophyllaeeze is increased to 43. The limits of Tibet as defined by 
Mr. Hemsley in his “Flora” are strictly adhered to: otherwise further 
additions to the Himalayan Flora would have been included, on the confines 
of Tibet, but politically within the area of Sikkim and Kashmir. 
Mr. Hemsley has elsewhere pointed out the misapplication of the name of 
“ West Tibet ” to a province of Kashmir.
