COELOPLEURUM 
Perennial, stout, glabrous but puberulent in the inflorescence, along seacoasts. 
Leaves 2—3-ternate; petioles very large, inflated. Flowers greenish-white; umbels many- 
rayed; involucre few-leaved, deciduous; involucel-bracts many, linear-lanceolate, small 
or rarely conspicuous. Calyx-lobes none. Fruit oblong, slightly flattened laterally if 
at all, glabrous; ribs very thick, corky, becoming hollow; oil-tubes small, | in each in- 
terval, |—2 under each rib, 2 on the commissure side. (Gk. koilos—hollow, pleuron—=a 
rib; from the hollow fruit-ribs. ) 
A. Leaflets acute or acuminate, usually narrowed at base, less than 5 cm. long; fruit 
3 mm. wide. W. (C. gmelini for our region.) 
C. longipes C. & R.
