COLLECTED IN CENTRAL TIBET. 133 
examined in connection with Mr. Thorold’s; the plants for the 
greater part being of the same habit and diminutive size. More 
than half of them, however, are different species; and most of 
them had previously only been collected by Przewalsky, from 
whose specimens the lamented Maximowicz described them. 
Several, it will be seen, too, were previously only known from 
the extreme western part of Tibet. In all cases where the 
species are different from Thorold’s their general distribution is 
given. The localities, altitudes, and geographical positions were 
supplied by Mr. Rockhill. 
Mr. Rockhill also brought home leaves of the famous “ white 
sandalwood tree” of Kumbum, Syringa villosa, Vahl, which he 
erroneously refers to as Philadelphus coronarius, Linn., in his 
‘Land of the Lamas.’ 
Enumeration of the Plants collected by
