 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: lvs. generally 

 oblong. 



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

 fblia, 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. : lvs. oblong to obovate-oblong, usually

 1M~2H in. long, very finely serrate nearl}' or quite to

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

 vate-oblong to oblanceolate or linear, about J^in. long; 

 top of ovary glabrous or sometimes slightly woolly; fr.

 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. Bartraminna in having the sepals on 

 the immature fr. upright or only slightly spreading; in 

 the other species they are recurved. 



EE. Apex of lvs. very acute or shortly acuminate. 



8. asiatica, Endl. (-4. canadensis var. asidtica, Miq. 

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

 slender spreading branches: lvs. ovate to oblong-

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

 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;
