Involucre none. Involucels of several or numerous bracts. Calyx-teeth mostly obsolete. Stylopodium depressed or none. Fruit oval, oblong or orbicular, glabrous or pubescent, dorsally compressed. Carpels with filiform dorsal and intermediate ribs, the lateral ones broadly winged; oil-tubes 1-4 (rarely more) in the intervals, 2-10 on the commissural side. Seed-face flat or slightly concave. [Name in honor of Cogswell.] About 60 species, of western North America. Type species : Cogswellia villosa (Raf.) Spreng. The species of this genus were previously referred to the Old World Peucedanum and their specific names wrongly applied. Flowers white or pinkish. i. C, orientalis. Flowers yellow. Fruit glabrous; involucel-bracts united. 2. C. daucifolia. Fruit finely pubescent; involucel-bracts linear, distinct. 3. C. foeniculacea. I. Cogswellia orientalis (Coult. & Rose) M. E. Jones. Fig. 3117. White-flowered Lomatium orientate Coult. & Rose, Contr. U. S. Nat. Herb. 7: 220, 1900. Cogswellia orientalis M. E. Jones, Contr. West. Bot. 12: 33. 1908. Finely pubescent, the leaves and peduncles 3-8' high. Root elongated, often swollen in places. Leaves bipinnate, the segments ob- long or ovate, generally pinnatifid into linear or linear-oblong obtusish lobes; bracts of the involucels lanceolate, scarious-raargined; um- bel 4-8-rayed, the rays unequal, I'-iV long in fruit; pedicels i&quot
