470 CAPRIFOLIACEAE (HONEYSUCKLE FAMILY) 



ioles and thread-like upright peduncles forking into 2 pedicels at the top, 

 each bearing a delicate and fragrant nodding flower. Calyx-teeth 5, awl- 

 shaped, deciduous. Corolla purple and whitish, hairy inside, narrow bell- 

 shaped, almost equally 5-lobed. Stamens 4, 2 of them shorter, inserted 

 toward the base of the corolla. Ovary and the small dry pod 3-celled, but 

 only 1-seeded, 2 of the cells having only abortive ovules. 



1. Linnaea americana Forbes, Hort. Woburn 135. 1833. Somewhat pubes- 

 cent: leaves obovate and rotund, 1-2 cm. long, crenately few-toothed, some- 

 what rugose-veiny: peduncles filiform, terminating ascending, short, leafy 

 branches, bearing at summit a pair of small bracts, and from the axil of each 

 a filiform 1-flowered pedicel; pedicels similarly 2-bracteolate at summit, and 

 a pair of larger, ovate, glandular-hairy inner bracelets subtending the ovary: 

 flowers nodding. L. borealis. From the mountains of California, Colorado, 

 and Maryland, northward to the arctic regions. 



4. SYMPHORICARPOS * L. BUCKBRUSH 



Low and branching upright shrubs with short-petioled leaves, which are 

 entire, wavy-toothed, or lobed on the young shoots. Flowers white, tinged 

 with rose-color; in close short spikes or clusters. Calyx-teeth short, persist- 

 ent. Corolla regularly 4-5-lobed, with as many short stamens inserted into 

 its throat. Ovary 4-celled, only 2 of the cells with a fertile ovule; the berry 

 therefore 4-celled but only 2-seeded. Seeds bony. 



Corolla short-campanulate, 3-4 mm. long. 



Leaves thick; stamens and style exserted 1. S. occidentalis. 



Leaves rather thin; stamens and style included . . . . 2. S. racemosus. 

 Corolla longer (6-1 2 mm.), long-campanulate to tubular-funnelfonn 



Leaves tomentulose or finely pubescent . . . . . 3. S. rotundifolius. 



Leaves glabrous or nearly so ....... 4. 8. oreophilus. 



1. Symphoricarpos occidentalis Hook. Fl. Bor. Am. 1 : 285. 1833. Robust, 

 glabrous or slightly pubescent: leaves oval or oblong, thickish (larger 5 cm. 

 long) : axillary flower-clusters not rarely pedunculate, sometimes becoming 

 spicate and 2-3 cm. long: corolla 3-5 mm. high, 5-cleft to beyond- the middle, 

 within densely villous-hirsute with long beard-like hairs: stamens and style 

 more or less exserted. WOLFBERRY. Mountains of Colorado and Montana, 

 northward and eastward. 



la. Symphoricarpos occidentalis quercifolia A. Nels. Stems short, simple, 

 erect: leaves large, coarsely and deeply undulate-toothed. Infrequent; on 

 the plains in northern Wyoming. 



2. Symphoricarpos racemosus Michx. Fl. 1: 107. 1803. More slender and 

 glabrous: leaves round-oval to oblong, smaller: axillary clusters mostly few- 

 flowered, or lowest 1-flowered: corolla 4 mm. high, 5-lobed above the middle, 

 moderately villous-bearded within, narrowed at base: stamens and style not 

 exserted. SNOWBERRY. Across the continent. 



2a. Symphoricarpos racemosus pauciflorus Robbins, Gray, Man. Ed. 5. 

 203. 1867. Low, more spreading: leaves commonly only 2-3 cm. long, strongly 

 whitened underneath: flowers solitary in the axils of the upper leaves, few and 

 loosely spicate in the terminal cluster. Mountains of Colorado to those of 

 Oregon, Vermont, and northward. 



3. Symphoricarpos rotundifolius Gray, PI. Wright. 2: 66. 1853. Tomen- 

 tulose or glabrate; stems rigid, much-branched, 4-10 dm. high: leaves or- 

 bicular to oblong-elliptical, thickish, 1-2 cm. long, entire or coarsely lobed: 

 corolla elongated-campanulate, 6-8 mm. long, the tube pubescent within be- 

 low the stamens, twice or thrice the length of the broad lobes: stamens and 

 style included: fruit white, globular or oblong: nutlets oval, equally broad and 

 obtuse at both ends. Throughout our range and west to the Pacific. 



* The familiar coral-berry, Symphoricarpos orbiculatus Moench, has been reported from 

 Colorado. It is easily recognized by the clustered coral-red berries which persist through 

 the winter.
