Heteromorpha.| | LXVIII. UMBELLIFERE (HIERN). 11 
Annesorhiza abyssinica, A. Br. in Flora (Bot. Zeit.) 1841, i. 337 -340, tab, 2, fig. 
B., was described only from the fruit. The description seems to suit Heteromorpha 
better than Annesorhiza, and it is possible that the fruit belonged to H. arborescens, 
Ch. and Schl.
