white fls. solitary, fascicled, or umbelled, the calyx-tube 

 narrowly campanulate and the petals obovate or linear- 

 oblong: 1 vs. ovate-lanceolate or oblong-lanceolate, cau- 

 date-acuminate, sharply serrate, glabrous, 3-5 in. long, 

 the petiole with 2-4 glands: fr. oblong or ellipsoid, 

 obtuse at both ends, with scanty yellow or reddish acid 

 flesh; stone bony and furrowed. Temp. Himalaya, 

 3,000-8,000 ft. The name is catalogued in S. Calif., 

 with the statement that the tree "blossoms in November 

 and ripens its fruit in April." Hooker (Fl. Brit. India) 

 places it with species having "flowers appearing before 

 the leaves. 7 ' 



62. campanulata, Maxim. (P. cerasmdes var. cam- 

 panulaia, Koidz.). Closely related to P. cerasoides: 

 tree, to 25 ft.: Ivs. ovate to elliptic-ovate, glabrous, 

 usually doubly serrate, 3-5 in. long: fls. pendulous, 

 campanulate, %in. long, deep rose-colored; calyx 

 purple: fr. ovoid, K m - l n g> red. Formosa, probably 

 Liu-kiu Isls., cult, in S. Japan. Gn. 56:300 (as P. 

 pendula). Very ornamental; not hardy N. A beautiful 

 species as grown in Japan. The Himalayan species 

 (P. cerasoides) has more coriaceous and more sharply 

 toothed Ivs. in which double serration is usually not so 

 marked. 



63. riifa, Steud. Small tree, to 20 ft., the young 

 growth densely tomentose: Ivs. elliptic-lanceolate or 

 oblong-lanceolate, 14 in. long, narrowed to very short 

 petiole, long-acuminate, glabrous or puberulent on rib 

 or nerves above and beneath, very sharply glandular- 

 serrate; petiole pubescent, glandless; stipules thread- 

 like and laciniate: fls. pink, J^in. diam., solitary, paired 

 or fascicled in the axils of previous year's growth, 

 appearing with the Ivs., the stalks longer than petiole; 

 calyx-tube urn-shaped, glabrous, the lobes triangular 

 and dentate; petals small and orbicular: fr. ellipsoidal, 

 on lengthened stalks, fleshy, red. Nepal and Sikkim, 

 12,000 ft. altitude. Recently cult, in England. 



cc. Floral involucre either small or the Ivs. prominently 

 lobulate or incised-doiMe-serrate. 



D. Lvs. shortly or rather deeply serrate: involucre small, 

 % to about %in. long: fls. vrith the Ivs. or preceding 

 them, the umbels sessile or the peduncles %in. or 

 less long: fr. mostly black. The early spring-flower- 

 ing cherries of Japan. 



64. suohirtella, Miq. (P. Miqueliana, Maxim. P. 

 Herincquiana var. ascendens, Schneid.). Plant a large 

 shrub or small forking tree, with erect branches: Ivs. 

 shorter and relatively broader than in var. pendula 

 (blade about 2 in. long except on terminal shoots), oval 

 or ovate, abruptly narrowed above and below, sharply 

 and more or less doubly serrate, more hairy beneath 

 and sometimes thinly short-hairy above, the glands 

 small or wanting: fls. 1 in*, across. Much cult, in Japan, 

 but unknown wild; less known in this country than 

 var. pendula, but perhaps more beautiful. B.M. 7508.

 31 : 283. This is the spring cherry of Japan and said by 

 Wilson to be "the most floriferous and perhaps the 

 most delightful of all Japanese cherries." Appears to 

 have been intro. into N. Amer. first in 1894 by the 

 Arnold Arboretum. The fls. normally appear in 

 advance of the Ivs., varying in color from nearly white to 

 pink: calyx reddish. Sometimes a few fls. appear in 

 autumn. Wilson writes that in its typical form this 

 species may be separated from its varieties in herbarium 

 material by its usually smaller and more glabrous lys. 

 and by its very numerous fls. which have less hairy 

 and more highly colored calyx-tube and sepals. In 

 living trees, the species is marked by its small size and 

 ascending branches.

CHERRY. Fig. 3242. Small tree, with drooping crooked 

 branches: Ivs. lance-elliptic to oblong-oval or oval on 

 older shoots (blade 3 i in. long), acuminate, mostly 

 narrowed at base, sharp-serrate, usually with a pair of 

 large glands at base of blade or on apex of petiole, 

 glabrous above, thinly hairy on rib and veins under- 

 neath: fls. %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 funnelform and red; style hairy: fr. 

 very small, globular, black-red, somewhat astringent.

 the handsomest of early-flowering trees, producing its 

 chaste pink fls. in profusion. Hardy in Cent. N. Y. 

 Seedlings sometimes have more erect and spreading

branches. Should be grown from seeds or worked on 

 the upright forms of the species, according to Wilson, 

 for it does not thrive on the European cherry stocks. 



Var. ascendens, Wilson (P. pendula var. ascendens, 

 Makino. P. Hosakra var. ascendens, Koidz. P. Her- 

 incquiana, Koehne. P. microlepis, Koehne). Regarded 

 by Wilson as the prototype of P. subhirteUa and var. 

 pendula. A tall strong tree with massive wide-spread- 

 ing branches but the branchlets rather sparse and 

 causing the head to have a thin appearance: Ivs. some- 

 what larger than in P. subhirteUa itself. Differs only in 

 habit from var. pendula, and the two cannot be dis- 

 tinguished on the herbarium sheet. It is cult, in Japan, 

 but is yet unknown as a horticultural plant in N. Amer. 

 and Eu., although recently intro. Indigenous in Cent. 

 China and probably also in Korea and Japan. 



Var. autumnalis, Makino (P. subhirteUa var. 

 Fukubdna, Makino. P. autumnalis, Koehne. P. 

 Makinodna, Koehne. P. microlepis var. Smithii, 

 Koehne. P. Cerasus Chealii pendula, Hort.). An 

 abnormal form, semi-double, blooming in April and 

 again in Oct.; bush-like in stature, with slender wide- 

 spreading branches. G.C. III. 52:432; 58:244. Gn.
