 floccose-tomentose at first, very soon becoming glabrous: 

 racemes many-fld., upright, short and dense, slightly 

 tomentose at first; fls. rather small; petals oblong to 

 narrowly oblong, H-^in. long; sepals short: summit of 

 the ovary woolly: fr. nearly black, bloomy. May; fr. 

 in July. Mich, to Ore. and Wash. S.S. 4:196. S.F. 

 1:185; 5:415. G.M. 52:143 (habit). Var. fldrida, 

 Schneid. (A. fldrida, Lindl. A. oxyodon, Koehne). Lys. 

 and racemes glabrous or nearly so from the begin- 

 ning. B.R. 19:1589. Var. pfimila, Schneid. (A. cana- 

 densis var. pumila, Nutt.). Glabrous like the pre- 

 ceding var., but very low and stoloniferous. 



cc. Teethoflvs. 7-15 to l /in.; Ivs. finely and closely serrate. 



D. Lvs. tomentose when young. 



E. Apex of Ivs. obtuse, rounded or sub-acute.

5. stolonifera, Wiegand (A. spicata, Brit. & 

 Brown, in part, not Koch. A. ovalis of many authors, 

 not Medikus). Upright stoloniferous shrub, 1-4 ft. high, 

 forming patches: Ivs. oval, rarely oval-oblong or 

 orbicular, rounded at the base or rarely subcordate, 

 12 in. long, finely serrate, usually quite or nearly 

 entire on the lower third, glabrous above, densely 

 white-tomentose beneath when young: racemes short, 

 dense, upright, tomentose or nearly glabrous; fls. 

 small; petals obovate-oblong, about J^in. long; top of 

 ovary woolly: fr. purplish black, bloomy, juicy and 

 sweet. May, a few days later than A. Isevis; 



fr. in July. Newfoundland and Maine to Va. 



6. ovalis, Borkh. (A. spicata, Koch, Cralx- 

 gus spicata, Lam.). Bushy shrub with numer- 

 ous sts., to 12 ft.: Ivs. oval to obovate, some- 

 times oval-oblong, lJ^-2^ in. long, serrate 

 to the base, white-tomentose beneath when 

 young: racemes upright, woolly; petals obovate, 

 long; top of ovary woolly: fr. bluish black, with the 

 sepals upright and slightly spreading. M.D.G. 1900: 

 496. This is possibly a hybrid between the preceding 

 and the following species; much cult, in Eu. 



FF. Top of ovary glabrous or nearly so: Ivs. generally 

 oblong. 



7. oblongifdlia, Roem. (A. canadensis var. oblongi- 

 folia, Torr. & Gray. A. Botryapium, Brit. & Brown, 

 in part. A. obovalis, Ashe.). Shrub, with slender upright 

 sts. growing in rather dense clumps, but not stolo- 

 niferous, to 25 ft. : Ivs. oblong to obovate-oblong, usually 

 rounded at the base, and rounded or acute at the apex, 

 1/4-2 H in. long, very finely serrate nearly or quite to 

 the base, white-tomentose beneath when young: racemes 

 short, dense and upright, silky-tomentose; petals obo- 

 vate-oblong to oblanceolate or linear, about H'n. long; 

 top of ovary glabrous or sometimes slightly woolly; fr. 

 nearly black, with bloom, sweet. May, with A. Isevis; fr. 

 in June. Maine to S. C. S.S. 4:195. Em. 2:503 (lower 

 figure). B.M. 7619. G.C. III. 21:333. D.G.M. 1900: 

 497 (habit). This differs from all other species except 

 A. ovalis and A. Bartramiana in having the sepals on 

 the immature fr. upright or only slightly spreading; in 

 the other species they are recurved. 



BE. Apex of Ivs. very acute or shortly acuminate. 



8. asiatica, Endl. (A. canadensis var. asidtica, Miq. 

 A. japdnica, Hort.). Shrub or tree, to 40 ft., with 

 slender spreading branches: Ivs. ovate to oblong- 

 elliptic, acute, rounded or subcordate at the base, 2-3 

 in. long, finely serrate all around, densely white or yel- 

 low tomentose beneath when young: racemes rather 

 dense, nodding, woolly, top of ovary woolly: fr. bluish 

 black. May; fr. in Sept. Japan, Korea. S.Z. 1:42. 

 S.I.F. 1:47. Var. sinica, Schneid. Lvs. less tomentose, 

 often finally glabrous, smaller, usually serrate only 

 above the middle. China.

9. canadensis, Medikus (A. Botryapium, Borkh. A. 

 canadensis var. Botryapium, Torr. & Gray. A. cana- 

 densis var. tomentula, Sarg.). SERVICE-BERRY. Bushy 

 tree, fastigiately branched: st. solitary or few, some- 

 times shrubby: Ivs. generally obovate, less often ovate, 

 oval or oblong, acute or acuminate, usually cordate 

 at the base, lj-8H in. long, sharply serrate quite or 

 nearly to the base, densely white-tomentose beneath 

 when young, less so above, tomentum usually partly 

 persistent: racemes rather dense, nodding, silky-tomen- 

 tose; petals linear or linear-oblong, about Hin. long; 

 top of ovary glabrous or slightly hairy: fr. maroon- 

 purple, tasteless. May, early, before the Ivs.; fr. in June. 

 Maine to Iowa, Mo. and south to Ga. and La. S.S. 4: 

 194. B.R. 14:1174. Gn. 73, p. 239 (habit; may be A. 

 oblongifolia). -This is the only species with the Ivs. 

 tomentose on both surfaces when young. 



DD. Lvs. quite glabrous. 



10. l&vis, Wiegand (A. canadensis, Gray, not 

 Medikus). Irregularly branched tree, with spreading 



branches, to 40 ft., sometimes shrubby: Ivs. oval-ovate 

 to ovate-oblong, short-acuminate, subcordate or 

 rotundate at the base, rarely broadly cuneate, 1J^-2J^ 

 in. long, sharply serrate nearly to the base, quite 

 glabrous and purplish when young: racemes slender, 

 many-fld., drooping, glabrous or nearly so, lower 

 pedicels very long, in fl. about 1 in., in fr. sometimes 2 

 in. long; petals oblong-linear, about J^in. long; top of 

 ovary glabrous: fr. purple or nearly black, bloomy, 

 juicy and fairly sweet. May; fr. in June. From New- 

 foundland to Mich, and Kans., south to Ga. and 

 Ala. Em. 2:503 (upper figures). H.T. 242. M.D.G. 

 1900:494, 495. G. 16:48; 34:343 (habit). G.M. 

 44:306 (habit). This is the most graceful and the 

 handsomest species in bloom, differing from all other 

 species in the purplish young foliage and the drooping 

 racemes. 



AA. Fls. solitary or 2 or 3 at the end of the branchlets; 



petals broad, obovate: Ivs. imbricate in the bud, 



flat when unfolding; petioles short, less than %in. 



long.

A.argiita, Nutt.). Fig. 188. Shrub, to 8 ft. : Ivs. elliptic
