ucre none; umbels compound; involucel-bracts several, small, narrow. Calyx-lobes prom- 
inent. Fruit globose; ribs inconspicuous, filiform, acutish; stylopodium conical; oil-tubes 
present in the intervals, 2 on the commissure side. W. (Latin name, from Gk. koris—a

bels somewhat compound; umbel-rays very unequal. Calyx-teeth very minute. Fruit 
oblong, glabrous; carpels much flattened dorsally; dorsal and intermediate ribs filiform: 
lateral ribs very much corky-thickened, bent toward the adjacent carpel leaving a hollow 
with a longtiudinal division in it; stylopodium depressed; oil-tubes very small, 4 groups 
of 3 on the convex side, 2 groups of 2 or 4 on the commissure side. (Gk. oros—=a 
mountain, gennao=to beget; they are mountain plants. ) ,
