ckemilbides. The :yidividual to which it approaches the near- 
est, is, doubtless, the H. capitata of Petit Thouars, an in- 
habitant of Tristan d*Acunha ; nor do I find any difference, 
except in the great hispidity of the stem and petioles of this 
latter ; upon the petioles, especially, the hairs standing out ho- 
rizontally to twice or thrice as great a length as the petiole is 
broad, whereas in my species, there are only short reddish hairs, 
giving the plant a rigidly downy appearance. Thouars even 
describes his H, capitata as having, like the H. Nepalensis, 
" fleurs monoiques par avortement." 
Captain Carmichael, in his excellent paper on the Na- 
tural History of Tristan d'Acunha, published in the 12th>o- 
lume of the Linnsean Transactions, has likewise given a good 
description of the H. capitata, and mentions a circumstance 
which equally exists in this plant, namely, the strong carrot- 
like taste of the leaf.
