L. verticillatum C. & R. Cont, Nat. Herb. iii, 320, t.12. Angelica 
verticillata Hook. I have neither specimens nor description of this spe-

16 CCELOPLEURUM Ledeb. Fl. Ross. ii, 361. 
Stout glabrous sea-coast perennials with 2-3-ternate leaves on 
very large inflated petioles, few-leaved involucre, involucel of 
numerous small bractlets and greenish-white flowers in many- 
rayed umbels. Calyx-lobes obsolete. Fruit,globose to oblong, 
slightly flattened laterally if at all, glabrous. Carpel with very 
thick and prominent corky ribs. Oil-tubes small, one in 
the interval arid 1 or 2 under each rib, 2-4 on the commissure, 
all adhering to the seed which is loose in the pericarp. — 
-C. Gmelini Ledeb. l.c. Stems stout, 1-3 feet high: leaflets ovate, 
acute irregularly cut-serrate 2-3 inches long, 1-14 inches broad: rays 1-114 
inches long: pedicels 3-4 lines iong: fruit globose to oblong 2-31¢ lines

of Washington, also on the Northern Atlantic coast. 
C. maritimum C. & R. Bot. Gaz. xiii, 145. ‘Stems 2-3 feet high: leaf-

pedicels 6-7 lines long: fruit oblong 3-344 lines long, with lateral ribs

17 OROGENIA Watson Bot. King. 120, t. 15. 
Dwarf glabrous nearly acaulescent plants from tuberous or 
fusiform roots with ternate leaves and linear segments, no in- 
volucre, involucels of few linear bractlets, and white flowers in 
‘subcompound umbels with very unequal rays. Calyx-lobes 
minute. Fruit oblong, very slightly flattened laterally, glabrous. 
Carpel much flattened dorsally with filiform dorsal and interme- 
diate ribs: laterals excessively corky-thickened, involute (that is, 
extended towards the other carpel leaving between the com- 
missural faces a cavity which is divided longitudinally by a 
thick corky projection from the middle of each face). Oil-tubes 
very small, 3 in the intervals, 2-4 on the commissure. 
0. linearifolia Watson 1.c. Stems slender, 1-2inches high, from a

oles; leaflets entire 1-2 inches long, 1-3 lines wide, obtuse: umbels ~-4-

ee projection strongly developed... Oregon and Washington to

0. fusiformis Watson Proc. Am. Acad. xxii, 474. Rather stout 3-6 
inches high, from a long fusiform root: leaves 2-3-ternate, with terminal
