Rocky moist woods, Canada! to Pennsylvania! and South Carolina? 

 and west to Oregon, Dr. •SroM/er.' Nuttall! '':i\U•\\?^, Boui^ard. May. — KcK)t 

 of a sweetish but rather disagreeable taste, and without the anise flavor of 

 the preceding species. Stem pale green, when growing in dry and exposed 

 situations hoary-pubescent in the young state, but in shady jdaces nearly 

 glabrous. Leaves sprinkled with short hairs on both surfaces, somewhat 

 shining beneath ; secondary divisions piniiatifid ; the segments oblong, in- 

 cisely and sharply serrate. Umbel with longer rays than in tho jireceding 

 species. Involucre and involucels at length deciduous. Petals with a short 

 incurved point. — The Oregon ])lant Mr. Nuttall considers a distinct species, 

 which he calls O. divaricata. 



42. GLYCOSMA. Nutl. viss. 



Margin of the calyx obsolete. Petals obovate, emarginate, witJi a short 

 inflexed point. Styles very short. Stylopodium depressed. Fruit linear- 

 oblong, compressed at the sides, solid, glabrous. Carpels with 5 acutely 

 carinate ribs. Intervals without vittre. Carpophore 2-cleft. — A large peren- 

 nial herb, with the sweet anisate odor of Myrrhis. Leaves bitcrnately di- 

 vided; the segments incisely serrate. Umbels opposite the leaves, and 

 terminal. Involucre and involucel none. Flowers white. 



Nearly allied to Myrrhis & Osmorhiza, differing from tho latter in its glabrous 

 fruit ; from the former in its solid fruit, extremely short styles, as well as in liabit ; 

 and from both, in the depressed (not conical) stylopodium, and the absence of in. 

 volucels. 



G. occidentalis (Nutt. ! mss.) 



Western side of the Blue Mountains of Oregon, Nuttall! In the interior 

 country of Oregon, Douglas !—P\anl slightly ])ubescent, 2-3 feet high, stout._ 

 Stem terete, fistulous, branching. Lower leaves on long petioles ; those of 

 the stem sessile: segments about 2 inches long, lanceolate-oblong; the ter- 

 minal one usually 3-parted or lobed. Umbels on long peduncles, solitary 

 in the axils of the upper leaves, or 2-3 together at the summit of the branches, 

 about 8-rayed ; tlie rays unecjual, several of them bearing only abortive 

 flowers. Fruit blackish-green and shining, about as large as in Osmorhiza, 

 somewhat rostrate, crowned with 2 very minute diverging styles. Seed 

 adhering to the integuments, so that the fruit is solid : albumen ^\^th a deep 

 furrow in front. 



Tribe XII. SMYRNIEiE. Koch; DC 



Fruit turgid, mostly laterally compressed or contracted. Carpcia 

 with 5 ribs ; the lateral ones marginal or placed opposite the mar- 

 gin, sometimes nearly obliterated. Seed involute, or sulcatc on the 

 face. — Umbels compound.
