 grandiflora). 



57. Sieboldii, Wittm. (Cerasus Sieboldii, Carr. P. 

 Pseudo-Cerasus var. Sieboldii, Maxim. Cerasus 

 Wdtereri, Hort.). JAPANESE FLOWERING CHERRY. 

 Strong-growing tree, like a sweet cherry, producing 

 showy pink double fls. with the Ivs. or just in advance 

 of them : Ivs. oval or ovate, abruptly acuminate, rounded 

 at base, densely soft-pilose beneath, the margins very 

 sharply gland-serrate; petiole hairy, usually bearing 1 

 or 2 small glands at apex: fls. 1-1 ^ in. across, 2-4 on 

 each short peduncle, the pedicels more or less pilose; 

 calyx-tube sparsely hairy or nearly glabrous, the ovate 

 rather obtuse entire lobes about equaling the tube; style 

 hairy at base. Japan, China. Known only in double- 

 fld. forms. R.H. 1*866, p. 371. Gn. 33, p. 420. G.W. 

 16, p. 355. Gt. 51:1494a. A.G. 12:400, 401. Wilson 

 writes that in habit and general appearance this species 

 strongly resembles P. Lannesiana, but is distinguished 

 by the pubescent caudate-acuminate Ivs. which are 

 sharply and often obscurely doubly serrate with small 

 teeth: fls. double or seminiouble, normally pink and 

 preceding the foliage; if the fls. precede the Ivs. the 

 peduncle is very short, when coetaneous with the foliage 

 the peduncle is much elongated and the fls. may then 

 be nearly or quite white. 



58. yedoensis, Mats. (P. paracerasus, Koehne. P. 

 yedoensis var. nudiflora, Koehne). Near P. serrulata, 

 differing in the pedicels, style, and usually exterior of 

 calyx being hairy; and near P. Sieboldii, differing in 

 young Ivs. pale green rather than bronzy, and calyx- 

 lobes sharp-serrate rather than entire. From Japan, but 

 wild specimens unknown. A tree-like shrub or good- 

 sized tree, with young growth hairy but becoming nearly 

 or quite glabrous in autumn or the second year: Ivs. 

 obovate or broadly ovate-elliptic, 3-5 in. long, acumi- 

 nate, strongly double-serrate with serratures acuminate 

 and gland-tipped, glabrous above, hairy on midrib and 

 veins beneath: fls. in a 3-6-fld. short-peduncled corymb 

 or cluster, with narrowly spatulate bracts, the pedicels 

 %-!% in. long and densely pilose; petals broad-ovate 

 or suborbicular, about }/in. long or a little more, 

 deeply emarginate; stamens about 37-39. The fls. are 

 slightly fragrant, in clusters of 2 to several, usually 

 preceding the Ivs. but sometimes coetaneous, white to 

 pink. "This is the cherry," writes Wilson, "so generally 

 planted in the parks, temple grounds, cemeteries, and 

 streets of Tokyo. Its flowering is the occasion of a 

 popular festival in the city of Tokyo. The oldest 

 authentically known trees were planted only a little 

 over 40 years ago, and the species was not recognized as 

 distinct till 1901. To Wilson the species is strongly 

 suggestive of a hybrid between P. subhirtella var. 

 ascendens and the wild form of P. Lannesiana. It is 

 hardy at the Arnold Arboretum. Taizanfukun (P. 

 fruticdsa f. ambigua, Miyoshi) is a form with young 

 shoots and petioles pubescent, fls. borne near ends of 

 shoots, moderately double and of medium size, pink. 



EE. Calyx-tube obtuse at base, campanulate or cylindrical: 



fr. red to black. 

 F. Blossoms appearing before the Ivs.: teeth of Ivs. large, 



acute, acuminate, or setaceous-acuminate: stone 



nearly or quite smooth. 



59. Conradinae, Koehne. Graceful tree, to 25 ft., with 

 rather thin glabrous or canescent shoots and large 

 foliage: Ivs. obovate or obovate-oblong, rarely roundish 

 ovate, 2-6 in. long and about half as wide, the base 

 usually rounded or even subcordate, apex narrow- 

 acuminate, double-serrate, the teeth gland-tipped, 

 glabrous or becoming so above and below; petiole about 

 3^in. long, glabrous, mostly with 2 glands; stipules lin- 

 ear, glandular-fimbriate: fls. whitish or pink, before the 

 Ivs.; peduncle sometimes Kin. long but usually very 

 short; pedicels (mostly 2-4 in the umbel) M~/4 m - l n g> 

 glabrous; calyx-tube glabrous; lobes or sepals erect- 

 spreading or spreading, more or less ovate, entire; 

 petals about ^in. long and J^in. broad, emarginate- 

 bilobed; style glabrous: fr. ovoid, M-Min- l n g> red- 

 Cent. China. 4 



FF. Blossoms appearing with the Ivs.: teeth of Ivs. small or 

 minute: stone prominently rugose. 



60. serrula, Franch. Tall tree, with young branches 

 thinly pubescent but becoming nearly or quite gla- 

 brous in autumn: Ivs. lanceolate, 2-4 in. long, base 

 rounded, apex acuminate, strongly but shortly double- 

 serrate, the teeth slender and gland-tipped, soon gla- 

 brous above, hairy along rib and in nerve-axils beneath, 

 at base usually with 3-5 glands; petiole M~H m - l n g> 

 glabrous, purplish. Apparently known to cult, in the 

 var. tibetica, Koehne, which has smaller teeth on the 

 Ivs.: fls. white, usually in 3's: fr. ovoid or globular- 

 ovoid, about J^in. long, red. W. China. Cult, abroad; 

 hardy in Mass. 



DD. Fruiting pedicel prominently thickened. 



61. cerasoides, D. Don (P. Puddum, Roxbg. Cerasus 

 Puddum, Wall. C. Phoshia, Hamilt.). A Himalayan 

 representative of P. Pseudo-Cerasus, described by Hooker 

 as a large tree of brilliant appearance in flower, glabrous 

 except the puberulous young shoots, the rose-red or
