Orumbella macounii C. & R. 
Ligusticum macounii C. & R. Contr. Nat. Herb. 1: 289. pi. 23. 1893. 
Only known from Cape Vancouver, Alaska. 
CONIOSELINUM Hoffm. Gen. Umb. NX VIII. 1814. 
Conioselinum scopulorum (Gray) C. & R. Contr. Nat. Herb. 7: 151. 1900. 
Contoselinum coloradense Osterhout, Muhlenbergia 5: 36. 1909, 
Mr. George EF. Osterhout has proposed a new species of Conioselinum which we 
are unable to separate from C. scopulorum. 
ANGELICA L. Sp. Pl. 250, 1753. 
Angelica dilatata A. Nelson, sp. noy. 
Glabrous, one-half to one meter high; lower leaves ternate, then pinnate; the 
upper nearly simply pinnate, with greatly dilated petioles, sometimes the uppermost 
reduced to the dilated petiole or the petiole tipped with a diminutive biternate leaf; 
leaflets broadly obovate to ovate, glaucous beneath, nearly or quite sessile, obscurely 
and somewhat irregularly serrate, or rarely with a basal lobe on one side; the 
dilated petioles 10 to 20 em. long, 5 to 6 em. broad when spread out; umbel about 
30-rayed, the involucre wanting or represented by 1 or 2 more or less conspicuous 
bracts; involucels none; rays 5 to 8 cm. long, nearly or quite glabrous; fruit oblong- 
elliptic, obscurely and sparsely hirsute, less than 5 mm. long; lateral wings broader 
than the low dorsal and intermediate ones; oil tubes solitary in all the intervals; 
pedicels unequal, usually much longer than the fruits. 
Collected by A. O, Garrett near mountain streams in City Creek Canyon, Salt Lake 
City, Utah, July 25, 1907, no. 2127; fruiting specimens same station in 1908. 
Most nearly allied to A. kingii (Wats.) C. & R., which differs in being an aquatic, 
with narrower leaflets, with only 5 to 10 rays, and with pedicels and fruit subequal. 
Type in Rocky Mountain Herbarium, Laramie, Wyoming; fragments and photo- 
graph in U.S. National Herbarium. 
PHELLOPTERUS Nutt. in Torr. & Gr, Fl. 1: 623. 1840. 
Phellopterus camporum Rydberg, Bull. Torr. Club 81: 574. 1904. 
We have not seen this species. 
AULOSPERMUM C. & R. Contr. Nat. Herb. 7: 174. 1900. 
Mr. George E. Osterhout has described the two following species 
from Colorado: 
Aulospermum angustatum Osterhout, Bull. Torr. Club 81: 358. 1904. 
Aulospermum planosum Osterhout, Bull. Torr. Club 30: 236. 1903. 
CYMOPTERUS Raf. Journ. Phys. 89: 100. 1819. 
Mr. Jones* has merged under Cymopterus the following genera of 
our Monograph: Aulospermum (. & R., Oreoxis Raf., Phellopterus 
Nutt., Pseudocymopterus C. & R., Pteryxia Nutt., and Rhysopterus 
C.&R. This wholesale merging of distinct groups of species is based 
on a conception with which we can not sympathize. In this same 
spirit Otto Kuntze united Cereus and Opuntia, Aster and Solidago, ete. 
The taxonomic work of to-day is moving away from the idea of con-
