I have no doubt that this is a species quite distinct from the Himalayan Aconites; but I am not 
sure where to place it, the material being in some respects too imperfect. There is only the mother- 
tuber, from which the flowering stem originated, with Clarke's specimen and no trace of a daughter-tuber 
although one should expect that it was completely developed at the time of collecting. Тһе tuber 
is about 1 em. thick near the base, where it gives off a few cylindric branches, 2-3 mm. thick. Just 
above this level the cambium seems to be continuous, but below, the tuber is broken up either into 
several branches or into strands which have become isolated by the decay of a portion of the 
parenchyma. Which is the case I cannot say, as the condition of the tuber is too bad. There are, 
however, in the Kew Herbarium three plants which represent young states of the same species all with 
the tubers still attached. They were collected in April by Watt (No. 6167) in practically the same 
locality. They are very young plants, having not more than 1 or 2 leaves developed. Their tubers 
are ovoid, 2-3 em. long and 0'7 cm. in diameter, bearing numerous root-fibres, some of which are 
thickened at the base. Their cambium forms in cross-section а continuous sinuous ring, and the 
xylem strands are particularly well developed. The taste is slightly bitter, followed by a tingling 
sensation, which, however, is not intense. In one of the plants a bud was found in the axil of a 
decayed scale at the base of the stem; it was evidently an innovation-bud the roots of which had 
not yet formed.
