708 Umbelliferae. 
Fruits flattened from front to back, with a single thick border 
(splitting only by the separation of the carpels), and covered with 
stiff hairs or tubercles. Carpels broad, with the ribs scarcely visible, 
and 1 or 3 vittas under the interstices. 
A small genus, chiefly from the Mediterranean region, with the appea- 
rance of Caucalis, but readily known by the flat fruit.
