gins closely callous-serrate: fls. small, fragrant, white, 

 in small terminal 'umbels in May and June (in New 

 York), appearing when the tree is in nearly full leaf: fr. 

 very small, dark red, not edible. Middle and southern 

 Europe and the Caucasus. — Extensively imported for 

 cherry-tree stocks, and sometimes run wild. 



EE. Shape of Ivs. distincthi longer than broad: fl.-clns- 



ters mostly lateral. 



F. Native Bird Cherries, bearing very small white fls. 



and a profusion of very small red fruits. 



21. Pennsylvdnica, Linn. Common Wild Bird or Pin 

 Cherky. Fig. 1994. Shallow-rooted tree with slender 

 red - barked branches, 

 25-40 ft. high and some- 

 times 13^ ft. in diam. of 

 trunk: Ivs. oblong-lan- 

 ceolate - acuminate, 

 light green and rather 

 thin, closely sharp-ser- 

 rate: fls. small, white, 

 slender - stalked, ap- 

 pearing with the Ivs., 

 in 2's or 3's: fr. the 

 size of a pea, light 

 cherry -red, the flesh 

 thin and sour and 

 somewhat puckery: 

 stone oblong. Sandy 

 and rocky lands, New- 

 foundland to British 

 Columbia, and south in 

 the mountains to Colo- 

 rado and N. Carolina. 

 S.S. 4:156. — Where the tree grows naturally, it often 

 sprouts inveterately and becomes a nuisance. When 

 bruised, the wood has a strong peach-like odor. It is 

 an interesting ornamental tree, however. In poor soils, 

 it is often lit.le more than a bush. On large trunks 

 the bark tends to peel in transverse strips. 



22. emargindta, Walp. Sometimes 40 ft. high : Ivs. 

 oblong-ovate or oblanceolate, mostly obtuse, closely 

 serrate, often somewhat pubescent beneath : fls. tinged 

 green, appearing with the Ivs. in (i-12 ft. glabrous or 

 pubescent corymbs: fr. larger than that of P. Pennsyl- 

 vanica, almost black when ripe, the flesh thin and bit- 

 ter: stone ovoid. High lands from Montana to British 

 Columbia and California. S.S. 4:157. — Sometimes of- 

 fered as an ornamental tree. 



FP. Exotic Cherries, hearing showy white or pink fls. in. 

 rather profuse clusters, the fruits larger {wheii 

 produced). 



2.3. semperfldrens, Ehrh. Everbloominq Cherev. 

 Ai>l-Saints' Cherry. Fig. 1995. Small tree or a bush, 

 usually top-worked on other stock, with a straggling oi 

 drooping habit, the slender twigs glabrous: Ivs. oval to 

 oblong -obovate, short-pointed (or acuminate on tlie 

 strong shoots), irregularly dentate, rather hard and 

 firm in texture: fls. white, on long, axillary and terminal 

 peduncles from May till September: fr. like a snuill 

 pie Cherry, but mostly longer-stalked and smaller, dark 

 red. — Probably a cultivated offshoot of the pie or BFo- 

 rello Cherry, P. Cerasus. By some its parent species 

 is thought to be distinct from P. Cerasns, and is se))a- 

 rated as P. flC)(7r/, Kocli. See No. 28. K.H. 1877:.W. On.

desirable ornamental subject. The leaves resemble 

 those of P. Cerasus, except that they are smaller. 

 Known in France as Cerisier de la Touissaint ("All 

 Saints' Cherry"). There is a form with yellow-varie- 

 gated Ivs.

 Weeping Rose-flowered Cherry. Fig. 1990. Small 

 tree, with drooping crooked branches: Ivs. ovate to ob 

 long-ovate, acuminate, very sharp-serrate, usually piibes- 

 cent beneath (at least on the strong shoots) : fls.^-1 in. 

 across, on long minutely pubescent stalks, in small 

 clusters from lateral buds before the Ivs. appear, rose- 

 pink, the petals notched at the tip, the calyx-tube fun- 

 nelform and red : fr. very small, globular, black-red, 

 somewhat astringent. Japan. R.H. 1870, p. 328. Gn.

 the handsomest of early-flowering trees, producing its 

 chaste pink flowers in profusion. Usually top-worked 

 on P. Avium. Hardy in central New York. Miquel's 

 name, subhirtella, is older than M&xunov:iQz^s pendula, 

 but Miquel confused two species, and it seems to be de- 

 sirable to drop the name. 



CC. Flower-clusters from lateral u-inter-buds, pedun- 

 cled and bearing 2-5 fls., with prominent ser- 

 rate bracts at the forks. 



25. PseMo-Cerasus, Lindl. {P. Puddum, Miq., not

 1998. Strong-growing tree, like a Sweet Cherry: Ivs. 

 ovate to oblong-ovate, long -acuminate, glabrous or 

 nearly so, the margin deeply sharp-serrate or toothed, 

 the stipules usually large and serrate on the young 

 growths: fls. large, pink or blush, appearing with the 

 first Ivs. or slightly in advance of them, on glabrous or 

 hairy pedicels, the peduncle branching: fr. spherical, 

 small, very dark red, subacid, somewhat astringent.

 the trees cultivated under this name is not well under- 

 stood. It is by no means certain that all of these plants 

 belong to P. Pseudo-Cerasus as 

 described by Lindley. Our knowl- 

 edge of the group is yet too im- 

 perfect to warrant a thorough 

 revision. 



Var. liort6nsis, Maxim. (Cfra-

 h)ta, Hort. C. Lannesi()na, Carr. 

 P.dondrium, Sieb.). This is the 

 famous ornamental Cherry of 

 Japan, where it is cultivated in 

 many forms, some of them being 

 full double. It differs from the 

 type in having somewhat nar- 

 rower Ivs.. with smaller serra- 

 tures and large fls. It is now fre- 

 quently planted in this country, 

 particularly the double-fld. forms, 

 but it is not quite as hardy as the
