In marslies at Point Lolws, anil southwanl to San Diego County. 



2. GEI. sarmentosa, Nutt. Very similar : leaves usually broader and more 

 open; lealiets acuminate, mostly smaller. — Torr. & Gray, Fl. i. 617. Phellan- 

 ilrium aquaticum, Pursh. 



Washington Territoiy and Oregon ; Pluuias Co., Lcnvmon. Tlie succulent stems have the taste 

 of Celery and are eaten by the 1 iidiaus. 



18. lilQUSTICUM, lann.

 late. Fruit ovate or oblong, with a broad commissure, somewhat dorsally com- 

 pressed ; ribs somewhat prominent and acute or narrowly winged, the lateral ones 

 usually broadest; oil-tubes obscure. Seed dorsally llattened, somewhat concave on 

 the face. Carpophore 2-parted. — Smooth perennials, usvudly tall; leaves pinnately 

 or ternate and pinnately decompound ; umbels many-rayed, naked or involuerate ; 

 flowers white. 



A genus of about 20 or '2.') species, of the northern hemispheie, chiefly of the OKI Woild and 

 most of tliem rather obscurely characterized. 



1. L. apiifolimn, lienth. & Hook. Rather stout, 2 to 4 feet high, branching 

 above : leaves ternate or biternate, the divisions pinnate or bipinnate ; segments 

 ovate, f to U inches long, laciniately pinuatilid, the lobes acute or acuminate : um- 

 bels long-})ed uncled, without involucre or rarely with 1 or 2 slender bracts, the rays 

 1 or 2 inches long, scabrous-puberulent above; involucels of several narrowly linear 

 entire bractlets ; pedicels slender, 2 or 3 lines long : fruit oval, 2 lines long, with a 

 conical stylophore ; carpels somewhat quadrangular ; ribs narrow, acute ; oil-tubes 

 3 to 5 in the intervals, 4 to 8 on the commissure : seed reniform in section, with 

 a medial longitutlinal ridge. — Gen. i. SJ12. Cpuquum apiifulium, Nutt. in Torr. 

 & Gray, Fl. i. 041. 



In the mountains from the Columbia River southward ; Yosemite Valley {Bolandcr) ; Big Tree 

 road and Ebbett's Vass{Breucr) ; Donner Lake, Torre i/. The Californiau plant agiees with that 

 of Oregon in all its cliaracters. Si)ecimens collei-ted at Tamalpais by Bigelow were rel'crred here 



by Dr. Torrey, probably correctly, but they were only in flower. What ap[)ears to be the same 



is also found in Colorado, but the Segments of the leaves are smaller, the involucels wanting, 



and the fruit (immature) Homewhat larger. 



A doubtful form, var. minus. Gray in herb., is found at Ostrander's Meadows (Bolandcr), and 



Ebbett's yiissiBrcuxi-) ; stem 9 to 15 inches hi^'h, with 1 or 2 umbels ; leaves all nearly radical, 



toruato-piunate ; the still immatiue fruit 2^ hues long, rather strongly ribbed, the seed more 



depressed and witliout the central ridge. 



L. «(;()i'Ul,(UiUM, (buy, tlm more imivalent species in tlio llocky MouutaiuH, may purhajia bo 



found in the norlheru Sierra Nevada, dlMlingiiishud by the more depres.s<iil-rcniform boed and 



by the oval more broadly winged fruit. 



19. SELINUM, Linn. 

 Characters of Liyusticum, but the fruit rather more prominently winged, the oil- 

 tubes solitary and conspicuous in the intervals, and the seed nearly flat on the face. 

 — Tall stout branching perennials, with jtinnately tk-compound leaves.
