UMBELLIFERiE. 323 



3. C. Oregaiiuiii, Wats. Proc. Am. Acad. xx. 368 (1885); Nutt. herb., 

 under Edusmia; Greene, Pitt. i. 274 (1889), under Atxnia. Aspect of the 

 last, but with lower leaves more finely divided, the short lobes linear; 

 fr. oblong, l^.^ — 2 lines long: seed sulcate beneath the oil-tubes, slightly 

 concave on the face, with central ridge. — In the mountains along our 

 northeastern borders. 



13. EULOPHUS, Nutlall. Our species at agreement with those of 

 the preceding genus in habit, general aspect, vegetative characters, 

 flowers, and even fruit, save that here the pericarp is thinner, the ribs 

 less prominent, the oil-tubes xisually several in the intervals, and the face 

 of the seed more concave. It is likely that a more natural classification 

 of these plants would be to merge them in Carnrn, or to receive the 

 entire series as one geographical genus under the name Atxnia. 



1. E. Califoriiicus, C. & R. Rev. Umb. 114 (1888); Gray, Proc. Am. 

 Acad. vii. 346 (1868), under Podusciadium; Torr. Pac. R. Rep. iv. 93 (1857), 

 under ChR'rophyllum. Root unknown: stem 3 — 4 ft. high, nearly simple: 

 lowest leaves 1 ft. long, triternately dissected into many linear entire or 

 toothed segments; uppermost simple: involucre and involucels of many 

 scarious lanceolate long-acuminate bracts: fr. linear-oblong, 4 lines long; 

 oil-tubes solitary in the intervals, 4 on the face: seed-face deeply con- 

 cave. — Stanislaus Co., near Knight's Ferry, thence southward to the 

 Santa Lucia Mts. May. 



2. E. Parishii, C. & R. 1. c; also Bot. Gaz. xii. 157 (1887), under Pint- 

 piiiella. Root deep-seated, tuberiform: stem solitary, erect, 1 — 2 ft. high: 

 lower leaves ternate, with linear-lanceolate leaflets 1 — 3 in. long, 2 — 5 

 lines wide, the terminal leaflet remote from the others; uppermost 

 simple: umbel 8 — 10-rayed, with few or no bracts; involucels of 2 — 6 

 narrowly lanceolate bractlets: fr. ovate or oblong, 1}{ — 2 lines long; 

 carpel with 5 slender ribs; oil-tubes 2 — 4 in the intervals, 6 on the face. — 

 Foothills of the Sierra, from Placer Co. southward. 



3. E. Bolanderi, C. & R. Rev. Umb. 112 (1888); Gray, Proc. Am. 

 Acad. vii. 346 (1868), under Podosciadiion. Stem 2 ft. high: leaves pin- 

 nate, the segments narrowly linear: umbels many-rayed, the rays 5 — 9 

 lines long; bractlets of the involucels scarious, exceeding the pedicels: 

 petals with the inflexed tip very long-acuminate: fr. oblong, 1% lines 

 long, the narrow ribs becoming elevated and undulate; oil-ttibes 2 — 5 in 

 the intervals but small and often obscure, 6 on the face: seed much com- 

 pressed dorsally. — In the Sierra, at higher elevations than the last, and 

 ranging northward. 



4. E. Fringlel, C. & R. 1. c. 113. Slender, 1^2 ft. high, the pinnately 

 compound leaves with broad inflated midrib, the divisions cut into nar- 

 rowly linear segments: umbel 3 8-rayed; involucre scant; involucels
