to S. Yakla even when depauperated with racemose inflorescence, we bring S, refusus and 
S. calthcpfolius very near together, distinguishable chiefly by the very slender babit of tlie 
latter and the narrow capitula with reddish pappus. Specimens of S. Yakla named by 
Clarke himself are in the Calcutta Herbarium and these agree with his description except 
as regards size j we have nothing approaching a plant 3 feet high. However in the field 
all these Senecios in their typical forms are appreciably distinct and J do not propose at 
present the reduction of any of them. Seneeio pach^carpus Clarke occurs in the same 
area, affects the drier slopes, is later in flowering, and is distinguished by the many-flowered 
capitula with 10 — 12 involucral bracts, and 7— -8 very long ligules. It comes nearest to 
the western S, amplexicaulis, and may ultimately be esteemed only a variety. 
8 , Kingianus is I believe a very local plant. I did not see it at Laghe nor in the 
Dikhchu Valley, and it was by that route that the Chola and Yakla were visited by Hooker 
and Clarke. It is a fine tall plant about 3 ft. high and just above and below Changu 
occurs in great abundance along with Seneeio Mortoni. As this particular corner was not 
opened up until the road in connection with the Tibet expedition of 1903 was made 
through it is practically certain that the plant was not obtained by Clarke. Its inflores- 
cence recalls that of 8 . Mortoni, but the leaves are quite different. Its narrow few-flowered 
capitula with three ligules distinguish it easily from the other species,

This slender plant is common near Yakla, but has long narrow ligules, and is therefore 
not identical with Clarke’s plant which has very short ligules. Perhaps both are only 
slender forms of the variable 8. Ligularia. The racemose types of the section are even 
more confused than the corymbose and I am unable to distinguish them clearly even after 
observation in the field. Clarke records 8. Aikinsoni from Yakla.

I found it difficult to distinguish in the field from slender forms of 8. retusus.
