 peduncled, terminal, l%-3 in. broad: fr. almost black, 

 ovoid. May, June. New Brunswick to Minn., south to 

 N. C. Em. 2:414. — It grows fairly well in drier situa- 



VICIA

2664. Viburnum Opulus (X %). 

 Single form of the common Snowball as it grows : 



i the wild. 



tions under trees. The foliage assumes a handsome 

 dark purple fall color. 



27. paucifldrum, Raf. Straggling shrub, attaining 5 

 ft.: lvs. orbicular to oval, coarsely dentate, with 3 short 

 lobes above the middle or often without, glabrous or 

 slightly pubescent beneath when young, 2-3% in. long: 

 cynies few-fld., small, on lateral, short, usually 2-lvd. 

 branchlets: fr. scarlet, subglobose. June. Labrador to 

 Alaska, south to Vt. and Colo, in the mountains. G.F. 

 3:5.— It does not usually succeed well in cultivation; 

 requires shade and moist porous soil. 



28. Gpulus, Linn. ( 1". Americ&num, Mill. Y.trilobum, 

 Marsh. V. opuloides, Mtihl. V. Mule, Pursh. V. Oxy- 

 cdccus, Pursh.). Cranberry-bush. High Cranberry. 

 Figs. 2664, 2665. Shrub, attaining 12 ft., with rather 

 smooth light gray branches and stems: lvs. broadly 

 ovate, 3-lobed, with coarsely dentate-serrate, acumi- 

 nate lobes, pubescent or almost glabrous beneath, 2-4 

 in. long: fls. white, in peduncled cymes, 3-4 in. broad: 

 fr. subglobose to oval, scarlet. May, June. New Bruns- 

 wick to Brit. Col., south to N. J. and Ore.; also in Eu. 

 and Asia. — Handsome native shrub, very decorative in 

 fruit, which begins to color by the end of July, remains 

 on the branches and keeps its bright scarlet color until 

 the following spring. The berries are not eaten by birds. 



Var. nanum. Jacq. A very 

 dwarf, compact, small- 

 leaved form ; flowers but 

 very rarely. Var. sterile, 

 DC. ( V. rbseum, and rosh- 

 ceum, Hort.). Guelder 

 Rose, Snow -ball. Fig. 

 2666. All fls. sterile, form- 

 ing large, globose heads. 

 Gng. 1:9. Gn. 56, p. 83.— 

 This is a very showy var., 

 but it lacks the decorative 

 fruits. There are also 

 variegated forms of the 

 type and of the sterile va- 

 riety. The American Cran- 

 berry-bush is considered 

 by some botanists a dis- 

 tinct species under the 

 n a m e V, Americanw m , 

 Mill., but differs little from 

 the European form, chiefly 

 by the more vigorous 

 growth, by the petioles 

 having a shallow rather broad channel and small glands, 

 and by the shorter peduncles and shorter stamens. 



29. Sargentii, Koehne. Similar to the preceding, of 

 more upright, denser habit: bark of stems darker, fis- 

 sured and somewhat corky, young branchlets with prom-

 Opulus (X K). 



inent lenticels: lvs. of thicker texture, pubescent or 

 glabrous beneath, the upper lvs. with much elongated 

 and usually entire middle lobe and small, short, spread- 

 ing lateral lobes; petioles with large glands: sterile 

 fls. larger, sometimes to 1% in. across; anthers purple: 

 fr. globose, in usually upright cymes. N. China, Japan. 



— Introduced under the name Viburnum Opulus from 

 Pekin. It does not seem to fruit as profusely as V. 

 Opulus. 



V. Burejceticum, Herd. & Kegel (V. Burejanum, Herd.). 

 Similar to V. Lantana. Lvs. narrower toward the base, vena- 

 tion like that of V. macrocephalum: cyme with 5 rays: fr. 

 pinkisli or yellowish. May. June. Eastern Siberia, Amurland. 

 Gt. 11:384.— T. cordifblium, Wall. Similar to V. alnifolium, 

 but cymes without radiant fls.: lvs. narrow: blooming before 

 the lvs. Himalayas.— I'. Dahftricum, Pall. Shrub, attaining 

 6 ft.: lvs. broadly ovate to oval, lK _ 2%in.: fls. funnelform, 

 in short, small panicles: fr. finally black. Dab.ur. to W. China. 



— V. densiflorum, Chapm. Closely allied to V. acerifolium. 

 Lower: lvs. smaller, l-2in., with mostly shorter lobes ornone: 

 cymes denser. W. Fla.— V. elltptimm. Hook. Shrub, attain- 

 ing 5 ft., allied to V. acerifolium, but lvs. not lobed, oval to el- 

 liptic-oblong : fr. oblong-oval, almost % in. long. Wash, to 

 Calif.— V. furcdtum, Blume. Closely allied to V. alnifolium. 

 but of upright habit and stamens shorter than corolla. Jap., 

 China. — V. Hancednum, Max. Allied to V. tomentosum: lvs. 

 broader, with few teeth above the middle. S. China. Tender. 

 Seems not in cultivation. See No. 22.— V. orientale. Pall. Al- 

 lied to V. acerifolhim: shrub, attaining 4 ft.: lvs. witn simple, 

 not fascicled hairs on the veins beneath and not glandular 

 dotted beneath: fr. red. June, July. W.Asia. Gt. 17:567.

2666. Snowball— Viburnum Opulus, var, sterile (X %). 



All the fertile flowers are changed to sterile, showy ones. 



VlCIA (classical Latin name). Vetch. Tare. More 

 than 100 species of herbs, mostly climbing, with pinnate 

 foliage, closely allied to Lathyrus, Pisum and Lens, but. 

 differing in minute floral characters: wings adhering to 

 the keel; style very slender, with beards or hairs all 

 around the upper part or only at the apex; pod flat, 2- 

 many-seeded, 2-valved and dehiscent, the seeds either 

 globular or tlattish; stamens diadelphous (9 and 1). 

 Flowers mostly blue or violet, sometimes yellowish or 

 white. The Vicias are widely spread in the northern 

 hemisphere and some of them in South America. About 

 two dozen species occur in North America, some of the 

 species introduced. Most of the Vicias are weedy or in- 

 significant looking plants, but a few are grown for the 

 bright flowers, others of late for green-manure crops 

 (see Cover-Crops) , and one ( V. Faba ) is a garden bean. 

 The species are mostly cool-season plants of easy cul- 

 ture. The interest in the Vetches in this country is 

 mostly for their value as soil covers and for foliage. V. 

 sativa and I'. villosa are the important species here at 

 present.
