Hydrocotyle] LXVII. UMBELLIFERA. 423 
LXVII. UMBELLIFER. 
This natural order is generally but poorly represented in the 
tropics. 
The carrot generally is cultivated in gardens in Angola proper 
and in Mossamedes, especially in the mountainous and highland 
regions, and is occasionally semi-spontaneous ; the “‘ Herva doce” of 
the Portuguese, Pimpinella Anisum L., is occasionally cultivated, 
as for instance near Quicuxe in the Loanda district, and also 
in Benguella. Cuminum Cyminum L. was nowhere seen by 
Welwitsch in Angola. 
The genus Hydrocotyle is transferred by some botanists to 
Araliaceae, principally because the xstivation of the corolla is 
valvate rather than imbricate as is usual in Umbellifere. This 
circumstance, Welwitsch remarks, only proves that the more 
carefully natural orders are studied, the more difficult it becomes 
to define them by clearly cut characters, and that it has been 
shown that on the same principle Crithmuwm must be placed in 
Araliaceae.
