chemilloides. The individual to which it approaches the near- 
est, is, doubtless, the HZ. capitata of Perit '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 Hf. arate 
“ fleurs monoiques par avortement.” — 
Captain CarMicHaEL, in his excellent paper on the Na- 
tural History of Tristan @ Acunha, published in the 12th'vo- 
lume of the Linnzan 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.
