several species of Clematis, none of which, however, 
have very conspicuous blooms. One, found in 
Shansi, has clusters of small, white, bell-shaped 
flowers. Another has a yellow blossom, while 
white and purple varieties occur. 
Primulas are very few in North China. There 
is one species, which grows along the dusty road- 
sides in Shansi. This resembles the Cowslip, 
but is larger and of a deep  crimson-brown 
colour. 
In the mountains west of K’uei-hua-ch’éng in 
North Shansi I found a single specimen of a light 
mauve-coloured Primula growing in the shade 
of some small timber. These are the only two 
members of this Order which have come to my 
notice. 
The Forget-me-not and Scorpion-grass (Myotis) 
are fairly common in Shansi, though members 
of this Order are not numerous. 
The White, the Scented and the Common 
Violet ali occur, in some places in great abundance. 
In North Shansi, pink blossoms are also not un- 
common. In the woods a small Pansy may 
sometimes be found, though it is rather rare. 
The Order Campanulaceze is represented by 
the Harebell, the Canterbury-bell and the Bell- 
flower, all of which are very common in the moun- 
tains of Shansi, where also and in Mongolia the 
Scabeus (Knautia sp.) is very abundant.
