ft. across, producing valuable wood: bark reddish and 

 lustrous; older branches chestnut-brown. Ivs. large, 

 oval or ovate, abruptly slenderly acuminate, coarsely 

 sharp-toothed, glabrous and lustrous, turning to crimson 

 and yellow in autumn, mostly with glands on petiole or 

 base of blade: fls. 2-4, very showy, rose-pink, appearing 

 before the Ivs., simple (not double), light rose-color, 

 about 1H if 1 - across, the pedicels slender, to \Y<i in. 

 long and with glandular serrate bracts or involucre; 

 petals obovate and emarginate; calyx-lobes ovate- 

 lanceolate, acute, entire; stamens 20-25: fr. size of pea, 

 bright red and becoming black and shining at maturity.

 III. 19:517; 55:346. G.F. 10:463 (shown reduced in 

 Fig. 3240). A tree of great ornamental value, hardy in 

 N Y. and Mass., bearing profusely of its handsome 

 broad fls. From P. serrulata it is distinguished by its 

 broader more coarsely serrate Ivs., of which the serra- 

 tures are scarcely pointed: Ivs. glabrous, bronze- 

 metallic green when unfolding, becoming yellow, orange, 

 and crimson in autumn ; serration simple and double on 

 same If., the teeth gland-tipped and mucronate or aris- 

 tate: fls. appearing with the Ivs. or slightly in advance, 

 ?2-l?4 m - across, rose, pink, or nearly white. The 

 forms of var. sachalinensis comprise some of the 

 hardiest and best of the flowering cherries of Cent, and 

 N. Japan. Of this important and very worthy variety, 

 the following formae are recognized by Wilson, most 

 of which have been intro. into N. Amer. recently and 

 all of which are named flowering cherries of Japan: 

 Benden, pale pink single, or nearly single fls., of small 

 horticultural value; Hakkasan, fls. pale pink, single or 

 nearly so, of little value ; dlbo-rdsea (P. Pseudo-Cerasus, 

 var. Shirofugen, Spaeth), fls. pink in bud and changing 

 to white as they expand, bearing 2 leafy green carpels 

 in the center, handsome; Fugenzo (P. Pseudo-Cerasus, 

 G.C. III. 19:517. P. Pseudo-Cerasus var. James Veitch, 

 Gt. 51:497. P. serrulata f. Veitchiana, Koehne), one of 

 the handsomest and known in cult, as James H. Veitch, 

 with rose-pink fls. bearing 2 leafy carpels in center; 

 Hisakura, fls. pale pink, double, one of the handsomest; 

 Horinji (Cerasus Juliana, fibre rbseo pleno, Carr. R.H. 

 1874, p. 20. C. Caproniana fibre roseo pleno, Van Houtte. 

 F.S. 21 : 2238), fls. in clusters, pale pink and semi- 

 double; fasciculaia (Itokukuri), fls. double pink, 

 clustered at ends of shoots; Kirin, late-flowering, 

 with large very double rose-colored fls., one of 

 the best; homogena (Kokonaye), fls. pink, long- 

 pedicelled and usually short-peduncled, double 

 or semi-double, pink; Masuyama, a fine form 

 with double rose-pink fls.; Ohnanden, a fine 

 form with rose-pink double or semi-double fls.; 

 Sekiyama, late, with large double rich rose-colored 

 fls., thought by Wilson to be "the handsomest of 

 all Japanese double-fld. cherries;" superba (Shogetsu), 

 rather late, good, very large, double, pale pink, long- 

 pedi celled; Shujaku, fls. borne in great profusion, 

 double, rose-pink; spiralis (Udzuzakura), a good form 

 producing pink double fls. freely near ends of branches, 

 with short peduncle and long pedicels. 



Primus Pseudo-Cerasus, Lindl. (P. involucrata, 

 Koehne), with which P. serrulata and other Japanese 

 flowering cherries have been confused, is an entirely 

 different species. It is not hardy in the northern states, 

 and apparently is not in cult, in this country except 

 perhaps under test in Calif, or elsewhwere. It belongs 

 to another subsection of the genus, more nearly allied 

 to P. canescens and P. lobulata, described under Nos. 

 65 and 66. It is grown in China and also in Japan for 

 its edible red subglobose apiculate fr., which is about 

 Hin. or less in diam. : small tree, to 25 ft., the shoots pale 

 gray to purplish and sparsely pubescent when young: 

 Ivs. sparsely pubescent but glabrous above at maturity, 

 ovate to broad-ovate, secondary veins few, acuminate, 

 rounded at base, doubly serrate with broadly triangu- 

 lar teeth: calyx-tube or cupula broadly obconic and 



180 



pubescent: fls. white, 2-5 in a cluster, 1 in. across; style 

 glabrous. Wilson states that "as a fruit tree it does 

 not compare in value with the European varieties 

 derived from P. Cerasus and P. avium." 



56. Lannesiana, Wilson (Cerasus Lannesiana, Carr. 

 P. serrulata Lannesiana, Koehne. P. Pseudo-Cerasus 

 var. hortensis, Maxim, in part). Fig. 3241. Differs 

 from P. serrulata in its pink fragrant fls. (white in 

 some of the formse), teeth of Ivs. long-aristate (rather 

 than short-aristate), bark pale gray rather than dark 

 chestnut-brown: Ivs. unfolding green or slightly reddish, 

 pale green beneath: calyx-tube or cupula campanulate, 

 glabrous. Japan. B.M. 8012 and G.C. III. 19:466 

 (both as P. Pseudo-Cerasus). R.H. 1872, p. 198 (note); 

 1873:351. Forma dlbida, Wilson (P. serrulata ff. dlbida 

 and speciosa, Koehne P. mutdbilis, Miyoshi, in part), 

 has single white fls. This forma is considered by Wilson 

 to be the parent of the cult, kind taken as the type of P. 

 Lannesiana and "also of the greater number of the dou- 

 ble-fld. Japanese cherries;" thought to be indigenous on 

 island of Oshima. It makes a tree to 30 ft. or more tall, 

 with thick spreading or somewhat ascending branches, 

 with a pale gray bark which is smooth even on old 

 trees : fls. pinkish in the bud, white when open, glabrous

throughout, either with the Ivs. or preceding them, the 

 peduncle usually J^-l in. long but sometimes wanting: 

 fr. ovoid, black, and shining. 



Some of the cult, kinds of P. Lannesiana in Japan, 

 many of which have recently been intro. into this coun- 

 try, are ranged by Wilson under the following formae: 

 donarium (P. donarium, Sieb.), fls. white and double, 

 fragrant; Fudanzakura, a precocious form that blooms 

 at almost any season, the single fls. white or nearly so, 

 of little horticultural value; Gozanomanioi, fls. white, 

 single, very fragrant; HabiUai, fls. single, white, and 

 fragrant, of minor value; Minakami, fls. very fragrant, 

 white, single or nearly so; Ohshibayama, of minor value, 

 the fls. white flushed pink, single or semi-double; 

 subfusca (Sumizome), one of the handsomest; with 

 very large fragrant single or nearly single white fls. 

 flushed pink; catardcta (Takinioi), fls. very fragrant, 

 single, white: Wasinowo, fls. single, fragrant, white; 

 Amayadori, excellent, botanically much like P. ser- 

 rulata var. sachalinensis, with double fls. clustered at 

 ends of branchlets, pale pink passing to white; Hata- 

 zakura, fls. semi-double, white tinged pink, the inner 

 petals reduced and rudimentary, said by Wilson to be 

 "a very beautiful cherry, with fls. suggestive of apple
