2i. CUtLOTLEURUM Lcdcl^. Fl. Ross. ii. 8Hl.— Stout 

 glabrous sea-coast perennials (somewhat pubcrulent in the inflores- 

 cence), with 2 to 3-ternate leaves on very large inflated petioles, 

 few-leaved deciduous involucre, involucels of numerous small 

 linear-lanceolate bractlets (sometimes conspicuous or even like the 

 leaves), and greenish-white flowers in many-rayed umbels. 



This genus is referred to Archungelica bv Bentham & Hooker, which 

 genus we have included under Angelica^, and in the same connection restor- 

 ed Cdilopleurum'^ to generic ranli. It differs from Angelica in the fact that 

 all the ribs are verv prominently thick and corky, and that the laterals are 

 not winged, although in C. maritimum they are broader than the dorsals. 

 The fruit is not at all dorsally flattened, the flattening being lateral, if any, 

 as in Liguslioum. The seed is soon loose in the pericarp, the oil-tubes 

 adhering to it. This fact, taken in connection with the vtry characteristic 

 ribs, serves to distinguish this genus from any Angelica, to which genus it 

 is nearly allied though Cfclopleurum maritimum and Angelica pinnata. 



1. C. Gmelini Ledeb. 1. c. Stem 1 to 8 feet high: leaflets 

 ovate. (with acute or obtuse base), acute, irregularly cut-serrate, 

 2 to 2% inches long, 1 to 1^ inches broad: rays 1 to 1}4 inches 

 long; pedicels 8 to 4 lines long: fruit globose to oblong, 2 to 3i^ 

 lines long, with ribs all nearly equal, and seed-face plane. (Fig.

This species very likely occurs on the coast of Washington Territory 

 and Oregon, but we have as yet seen no si)ecimens. So far as known it is 

 not found in the interior, the so-called Archaitgelica (imrlini of the Eocky 

 Mountains (so far as seen) being Selinum <,'ruyi. The plant from "Alpine 

 legion of White Mts. {()alie»)," in the Gray and Torrey herbaria, is probably 

 something else, but the specimens are much too young to determine.

 the Uintas are the same, and have been doubtfully referred to this species, 

 but in the absence ot fruit it is impossible to determine the relationship, 

 and the range is presumptive evidence against this reference. They may

 & Gray as a synonym of Archaitgelica Ci'melini DC . is Angelica genujle.va
