278 CArRlFOLlACE.E. Sainbucus. 



1. S. glauca, Nult. Arborescent, glabrous, or ofUai somewhat, jjubesceut with 

 short and still spreading hairs : U-allets 3 to D, of lirni tiixtiue, ovate or hmceohiti-,, 

 sharply serrate with rigiil s])reading teeth : cyme ilat, S-parted : I'ruit black, but very 

 glaucous, so appearing to bo white : nutlets obscunly rugose : pith of shoots white. 

 — Nutt. in Torr. & (Jray, Fl. ii. 13. 



Coiuinoii thiougliout the State, and north and east of it ; 6 to 18 feet high, sonictiiues with 

 trunk to 12 inilu-s in diiiineter. Not easy to distinguish from S. nitjra of luirojie extcjit by the 

 whitened fruit, it well may be S. Mexicaiui, i'resl, to wliieh it was referred by Toriey in Pacif. 

 U. l{ei). iv. 95, Hot. Me.x. Bound. 71, and in Bot. Wilkes Exp. 330, but with doubt. 



2. S. racemosa, Linn. Shrubby, mostly glabruus : leaflets 5 to 7, tliin, oblong- 

 lanceolate, much acuminate, very sharply serrate : cyme ovate or pyriform : fruit 

 bright red ; its nutlets obscurely rugose : pith of shoots brown. — Hook. V\. i. 27*J. 



Along the mountain ranj^es, in woods, extumiing far north, 'fiio ('alifornian and Hocky 

 Mountain si)eciniens are as glabrous as the European plant ; in British America and Alaska it is 

 commonly pubescent, as in the Atlantic States \'d,\''\^ty puhcns, S. pubciis, Michx. 



2, VIBURNUM, Linn. Arkow-wood, &c. 



Calyx 5-tootbed. Corolla wheel-shaptMl or open campanulate, deejjly and regu- 

 larly 5-lobed. Stamens 5, oxsertotl. Stigmas 1 to 3. " Jjerries," really drupes, 

 containing a single Hat or llattish hard seed-like stone. — Shrubs or small trees, 

 with simple, but commonly toothed, and sonuitimes deeply lobed leaves, and white 

 flowers in a compound terminal cyme. 



A genus represented by a dozen species in the Eastern United States, only two of which ex- 

 tend, well northward, to the Pacific. One of these is the Cranberry-tree, as well as the Snowball- 

 tree or Guelder Rose of ornamental cultivation: in this the cyme is radiate in the manner of 

 Hydraiuiea, the marginal flowers being neutral and greatly enlarged. There is one peculiar spe- 

 cies on the coast of Oregon, which extends into California, viz. : — 



L V. ellipticum, Ilook. Shrub 2 to 5 feet high, with scaly buds : leaves 

 broadly oval or elliptical, roundish or very obtuse at both ends, 3 - 5-ribbed from 

 the base, coarsely dentate above the middle, the lower surface and petioles with the 

 young shoots hairy : cyme dense, peduncled : flowers all perfect : fruits oval, bluish- 

 black (half an inch long) ; the stone grooved on both sides. — Hook. 1<'1. i. 280. 



In woods, Mendocino Co. (Kellogg) ; extending to the Columbia River. Related to I", pubcs- 

 cena and V. deututum of the Atlantic side. 



3. LINNJEA, Gronov. Twin-flower. 



Calyx 5-lobed ; the lobes subulate, deciduous. Corolla obscurely irregular, fun- 

 nelform, 5-lobed. Stamens cue fewer than the lobes of the corolla, i. e. 4, inserted 

 low down on the corolla, included, two of them shorter. Ovary and the small 

 dry fruit 3-celled, one cell with a suspended fertile ovule and seed, the two othei-s 

 with several abortive ovules. Style slender : stigma somewhat ca])itate. — Con- 

 tains a single species. 



L L. borealis, (Jronov. A low and almost herbaceous little evergreen, with 

 slender and crecjting or trailing stems : leaves round-oval, sparingly crenatc, nar- 

 rowed at base into sliort petioles : ptnluncles erect, slender, forking into two pedi- 

 cels at the top, each bearing a single delicate and fragrant nodding flower : corolla 

 tinged with p)urple or rose-color, hairy inside. 



iloist mossy woods, Mendocino Co. ; common in Oregon and eastward, extending all round the 

 northern cool-temperate zone. The California locality rests on Dr. Bolander's authoiity. It 

 would be interesting to know if the si)e('.imens are of the oidinary type, or of the variety longi- 

 flora, ToiT. in Bot. Wilkes Exped., which is the usual form in Oregon, and is remarkable for its 

 larger flowers, the tube of tlie corolla with a long bipering Imse, and the slmder calyx-lobes three 

 times longer than the ovary. In Colorado the ordinary form only is fountl.
