1989. Prunus pumila Sand Cherry (X }). No. 16. 



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. distinctly longer than broad: fl.-clus- 



ters mostly lateral. 



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

 and a profusion of very small red fruits. 



21. Pennsylvanica, Linn. COMMON WILD BIRD or PIN 

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

 red - barked branches, 



25-40 ft. high and some- 

 times 1% 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 p u c k e r y : 

 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 litLle more than a bush. On large trunks 

 the bark tends to peel in transverse strips. 



22. emarginata, 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 6-12 ft. glabrous or 

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

 vania, 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. \ 



FF. Exotic Cherries, bearing showy white or pink fls. in 

 rather profuse clusters, the fruits larger (when 

 produced). 



23. semperfldrens, Ehrh. EVERBLOOMING CHERRY. 

 ALL-SAINTS' CHERRY. Fig. 1995. Small tree or a bush, 

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

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

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

 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 small 

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

 red. Probably a cultivated offshoot of the pie or Mo- 

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

 is thought to be distinct from P. Cerasus, and is sepa- 

 rated as P. acida, Koch. See No. 28. R.H. 1877:50. Gn. 

 50, p. 313. Its habit of blooming all summer makes it a

desirable ornamental subject. The leaves resemble 

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

 Known in France as Cerisier de la Touis saint ("All 

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

 gated Ivs.

 WEEPING ROSE-FLOWERED CHERRY. Fig. 1996. Small 

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

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

 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. 1876, p. 328. Gn. 

 50:1095. G.F. 1:198; 2:487 (old tree). Gng. 2:269. 

 M.D.G. 1890:320-1. Var. ascendens, Makino, is an up- 

 right form. B.M. 7508. M.D.G. 1900:319, 320. -One of 

 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 Maximowicz's pendula, 

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

 sirable to drop the name. 



CO. Flower-clusters from lateral winter-buds, pedun- 

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

 rate bracts at the forks. 



25. Pseudo-C6rasus, Lindl. (P. Puddum, Miq., not 

 Roxbg. ). JAPANESE FLOWERING CHERRY. Figs. 1997, 

 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.

 G.F. 10:463. A.G. 12:402-3. The botanical status of 

 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. hort6nsis, Maxim. (Cera- 

 sus serratifblia, Lindl. C. serru- 

 ldta,Hort. C. Lannesiana, Carr. 

 P. donarium, 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
