SORBUS 



SORBUS 



3197 



ally rounded at the base, pinnately lobed with short, 

 broadly triangular, sharply serrate lobes, and with 6-9 

 pairs of veins, grayish or whitish tomentose beneath, 

 2M~4 in. long; petioles H-l in. long: fls. about Ypb.. 

 across, in broad, tomentose corymbs: fr. globose or 

 globose-ovoid, about J^in. high, orange to brownish red. 

 May, June. Occasionally occurring in Cent. Eu. H. 

 W. 3, p. 85. 



11. intermedia, Pers. (Pyrus intermedia, Ehrh. Sor- 

 bus scdndica, Fries. Aria suecica, Koehne. Hdhnia 

 suecica, Dipp.). Tree, 20-40 ft. high, with oval head: 

 lys. ovate to oblong-ovate, broadly cuneate at the base, 

 pinnately lobed with broad and short, irregularly ser- 

 rate lobes and 5^-8 pairs of veins, whitish tomentose 

 beneath, 2 l /^-A in. long; petioles J^-^in. long: fls. 

 about Join, across, in broad, tomentose corymbs: fr. 

 orange-red, globose or subglobose, about Y$&. high. 

 May. X. and Cent. Eu. S.I.F. 3:485. This is some- 

 times confounded with S. hybrida and considered to be a 

 hybrid of similar origin, but it is certainly a good species. 

 It never bears distinct Ifts. at the base and the sinuses 

 do not reach farther than one-third toward the middle. 



12. Aria, Crantz (Pyrus Aria, Ehrh. Aria nivea, 

 Host. Hdhnia Aria, Medikus). WHITE BEAM-TREE. 

 Fig. 3651. Tree, with broadly pyramidal or oval head, 

 25-50 ft. high: Ivs. elliptic to oblong-oval, usually 

 cuneate at the base, acute or obtuse at the apex, 

 sharply and doubly serrate, of firm texture, bright or 

 dark green and glabrous above, white-tomentose 

 beneath, 2-5 in. long; petioles Yy-yv&. long: fls. ^-%in. 

 across, in tomentose, 2-3-in.-broad corymbs: fr. sub- 

 globose, orange-red, about H m - high. May. Cent, 

 and S. Eu. to Himalayas and Siberia. G.M. 44:291. 

 H.W. 3:52. Desirable tree for dry and exposed situa- 

 tions, and very ornamental in foliage on account of the 

 contrasting colors of the upper and under sides of the Ivs. 

 Var. Decaisneana, Rehd. (Aria Decaisnedna, Lav. 

 Pyrus Decaisnedna, Nichols. Pyrus Aria var. majestica, 

 Prain. S. Aria var. majestica, Zabel). Lvs. elliptic or 

 ovate, irregularly doubly serrate, 37 in. long: infl. 

 3-4 in. across: fls. %in. across; stamens longer than 

 styles: fr. oval, J^in. across. B.M. 8184. Origin 

 unknown, probably from the Himalayas. Var. edulis, 

 Wenzig (Pyrus edulis, Willd. S. longifblia, Hedl.). Lvs. 

 elliptic-oblong to oblong, rounded or acute at the 

 apex, 2-5 in. long: fr. oval, ^-%in. high. There are 

 some garden forms, as vars. aurea, chrysophylla, and 

 lutescens, Hort., with more or less yellow foliage. 



13. umbellata, Fritsch^(5. meridiondlis, Guss. S. 

 flabellifdlia, S. Schau. S. Aria var. flabellifolia, Wenzig. 

 S. flabelldta, Hort.). Small tree, attaining 20 ft.: Ivs. 

 orbicular to broadly oval, obtuse, usually broadly 

 cuneate at the base, incisely lobed above the middle, 

 with the short lobes truncate or rounded and coarsely 

 toothed, with 5-7 pairs of veins, snowy white beneath, 

 1/^-2 Yi in. long: fls. scarcely J^in. across, in dense, 

 white-tomentose corymbs: fr. depressed-globose, 

 orange-red. S. E. Eu., W. Asia. Cult, in some nurser- 

 ies as Pyrus aurea striata. Var. cretica, Schneid. (S. 

 Aria var. cretica, Rehd. Aria graeca, Roem. S. Aria 

 var. graeca, Koch). Lvs. orbicular-obovate, doubly 

 serrate, scarcely lobed, with 6-11 pairs of veins, \Yr^ 

 in. long. S. E. Eu., W. Asia. 



14. alpina, Heynh. (Aronia densiflora, Spach. A. 

 Willdendwii, Zabel. S. Aria x Aronia arbutifolia). 

 Shrub, similar to S. Aria, but Ivs. smaller, densely 

 serrulate, with fewer and less straight veins: infl. and fls. 

 smaller; styles 3-4: fr. red or brownish red, J^in. 

 across. Of garden origin. From Aronia arbutifolia it 

 may be distinguished by usually larger Ivs. with more 

 numerous veins and with a less close and less glandular 

 serration and by larger fls. with only 3-4 styles. A 

 similar hybrid is S. Dippelii, Zabel (S. Aria x Aronia 

 melanocdrpa) with the Ivs. often finally glabrescent and 

 black frs. over Y$ai. across.
