. The Senecios of the section Ligularia are very difficult of discrimination in the herba- 
rium and are troublesome enough in the field. Both racemose and corymbose types are 
common on the Chola range and I had the opportunity of comparing the species in a fresh 
condition. Of the corymbose types the Flora of British India gives two species for the 
East Himalaya — /S'. Yakla reduced to 8 . amflexicaulis 8 . p achy car pus. I have 
had to add a new and very distinct species 8 . Kingianus. True 8 , amplexicaulis I have 
not seen in the East Himalayas and in my opinion 5. Yakla should be restored. None of 
the other allied species have its numerous short broad ligules. Clarke named his species 
after the pass known as Yak La. This pass I visited and Clarke’s plant is there at an 
elevation of 13 — 15,000 ft. It affects marshy ground, even tussocks in the streams and 
is usually one to two feet high. There is no Senecio of three feet high at 16,000 ft. in the 
Chola range, the altitude given in the Flora of British India ” though Clarke himself 
gives 12 — 15,000 ft. in Composite Indicm. The plant is nearly glabrous, with 1—2 
radical leaves, orbicular or reniform, 8—9 inches in diameter ; petiole not winged. 
Capitula comparatively few, 8—14, short and broad, drooping, many-flowered ; involucral 
bracts 16—18 acute or obtuse, half an inch long, connate below, slightly pubescent j 
ligules 15—18, scarcely exceeding the involucral bracts, broad, oboyate or elliptic, not 
linear oblong, more or less involute, pappus white, longer than the achene. However in its 
less developed form this species approaches 8 . ret%sus from which it is distinguished Jsy 
its corymbose inflorescence and short blunt ligules. 1 find Wallich’s original specimen of 
8. retusus has long narrow ligules and the plant is thus described by Clarke, though in the 
Flora of British India ” Hooker says short, broad.” In small specimens the corymbose 
inflorescence, not a very good chararacter at any time, is a negligible distinction and one is 
left with the character of the ligules and a difference in habit difficult to appreciate except 
in the field and possibly due to very wet habitat. If we refer all the short liguled forms
