Oregon, Mcnzies ! Nutiall! — This species, as Mr. Nuttall remarks, seems 

 more nearly allied to S. salicifolia than to S. Douglasii : indeed h does not 

 obviously differ from some states of that species, except in tlie very dense 

 and obtuse panicle. 



• * * Floii-icrs in large and loose compound panicles : calyx deeply 5-cleft, 

 spreading : disk wholly coherent, entire : ovules 2, collateral ! 



8. S. ariafolia (Smith) : leaves broadly ovate, petioled, obtuse, pinnati- 

 fidly incised or somewhat lobed, dentate with mucronate teeth, almost 

 glabrous above, canescently hairy or tomentose beneath ; panicle large and 

 loose, much branched, and, with the calyx, tomentose-pubescent ; seginents 

 of the calyx acute, spreading ; carpels 5, broad, compressed, margined, 

 very hirsute. — Smith! in Rees, cyd. ; Seringe, in DC. I.e.; Lindl. .' hot.

 and on the Kooskoosky River, Lewis ! June-July. — The ordinary form is 

 freciuently somewhat arborescent, according to Nuttall, with a stout trunk, 

 rising to the height of 12-14 feet. His S. dumosa is said to be a low shrub, 

 confined to mountain regions. Douglas's Californian specimens are quite 

 intermediate between the two, and probably came from the back countty : 

 the young leaves agree well with the description of Pursh. 



§ 3. Floioers ferjeet, sometimes ietramerous : disk obsolete : sepals reftexed : 

 carpels distinct, straight or sometimes eortorted : ovules about 2, one above 

 the other, pendulous : stigmas capitate, usually very large : seeds . . . . : 

 herbs with pinnately divided stipulate leaves: inflorescence paniculate- 

 cymose. — Ulmaria, Moench. 



/ 9. S. lobata (Murr.) : leaves pinnately 3-5-7-foliolate, often with sm.aller 

 stiijulate leaflets interposed ; lateral leaflets cuneifcmi at the base, palmate- 

 ly 3-parted or lobed ; the terminal one 7-9 pjuted, very large ; the lobes all 

 serrate, mostly incised or tootlied ; stipules reniform, persistent ; panicle very 

 compound, cymosely branched ; flowers large, deep rose-color ; sepals re- 

 flexed; styles short ; stigma very large; carpels 6-8, glabrous, straight. —

 high, glabrous, striate, and angled. Upper cauline leaves short, 3-lobed. 

 Flowers numerous, incompletely cymose. — The bruised leaves are said to 

 exhale an odor similar to that of the Winter green.
