the disk that crowns the ovary and surrounds the base of 
the 2 styles . Fruit consisting of 2 sefid-like dry carpels. — 
Limb of the calyx obsolete or a mere 5-toothed border. 
Petals mostly with the point indexed. Fruit of 2 carpels 
(called mericarps) cohering by their inner face (the com¬ 
missure ), when ripe separating from each other and usually 
suspended from the summit of a slender prolongation of the 
axis ( carpophore) : each carpel marked lengthwise with 5 
primary ribs, and often with 5 intermediate ( secondary ) 
ones ; in the interstices or intervals between them are com¬ 
monly lodged the oil-tubes ( vittce) which are longitudinal 
canals in the substance of the fruit, containing aromatic oil.* 
Seeds solitary and suspended from the summit of each cell, 
anatropous, with a minute embryo in hard horn-like albu¬ 
men. — Stems usually hollow. Leaves alternate, mostly 
compound, the petioles expanded or sheathing at the base. 
Umbels usually compound, when the secondary ones are 
termed umbellets: both often subtended by a whorl of 
bracts ( involucre and involucels).
