PYRUS 



PYRUS 



unknown in the wild. A useful and showy plant, bear- 

 ing profusely of bright red fls., with red calices and 

 pedicels, and holding its many little frs. well into winter 

 or even all winter. 



BB. Lvs. conduplicate (folded together lengthwise face to 



face in the bud), those on the strong shoots often lobed. 



c. Calyx persistent. 



29. Tschondskii, Maxim. (Mdlus Tschondskii, 

 Schneid.). Fig. 3294. Tree, 30-40 ft. with erect and 



open habit: Ivs. ovate- 

 acuminate, coarsely 

 serrate, with sharp 

 teeth, shining and 

 pilose above although 

 tomentose when young, 

 somewhat tomentose 

 beneath: fls. 2-5 

 together, white tinged 

 rose, on whitish hairy 

 pedicels about Kin. 

 long; calyx-tube whit- 

 ish hairy, the lobes or 

 sepals ovate -acute, 

 spreading in fl.; petals 

 about Kin. long.: fr. 

 obovoid, about 1 in. 

 diam.; calyx-lobes per- 

 sistent, erect or nearly 



^ jfc,- so, white-tomentose, 1 



in. or less diam., yellow 



/ with a rosy cheek.

Fig. 3294). 



30. yunnanensis, Franch. (P. Vdtchii, Hort. Mdlus 

 yunnanensis, Schneid. Eridlobus yunnensis, Schneid.). 

 Distinguished from P. Tschonoskii by its smaller fls. in 

 many-fld. clusters, much smaller frs. which are red and 

 with reflexed calyx-lobes, and by the Ivs. which are more 

 distinctly lobed and sharply close-serrate: a handsome 

 tree with spreading branches: Ivs. simple, broadly 

 ovate, with closely or finely toothed lobes: fr. small, 

 Kin. or less long, produced abundantly. China. G.M. 

 56:897. 



cc. Calyx deciduous. 



D. Styles glabrous at base: fr. ovoid: Ivs. prominently 

 lobed. 



31. transitdria, Batal. (Mdlus transitoria, Schneid.). 

 Young twigs, Ivs., and infl. more or less felty: Ivs. more 

 or less acute, 3-lobed, about 1 in. diam., petiole about 

 Min. long: infl. 3-8-fld.; peduncle, receptacle, and 

 calyx felty; petals broad-oblong, somewhat emarginate, 

 small-clawed, 5 times as long as the calyx; stamens 15; 

 styles 5 (rarely 4), more or less grown together, naked: 

 fr. globose, more or less hairy, about Min. diam. China. 

 Var. toringoides, Bailey (P. transitoria var. torin- 

 goides, Rehd.), is larger and more vigorous, the Ivs. 

 partly entire, frs. larger. W. China. 



DD. Styles villous at base: fr. ovoid: Ivs. prominently 

 lobed. 



32. kansuensis, Batal. (Mdlus kansuensis, Schneid. 

 Eridlobus kansuensis, Schneid.). A distinct species, 

 marked by the usually broad-ovate 3-5-lobed and 

 sharp-serrate glabrous or glabrescent Ivs. which are 3- 

 nerved at base, and by the ovoid red fr. from which 

 the calyx is deciduous: young twigs glabrous, red- 

 brown; buds of the same elongate, acute; scales only 

 finely ciliate: Ivs. dark green above, somewhat glandu- 

 lar on the nerves, somewhat paler beneath, glabrous or 

 slightly hairy on the nerves, subrotund in outline, 

 upper half palmately 3-lobed, lobes triangular, acute, 

 margin serrate, the side lobes somewhat shorter; 

 petiole IK in. or less long: infl. a false umbel; calyx 



acute, equaling the corolla; petals round, short-clawed, 

 more or less hairy inside; stamens 20; styles 3, hairy and 

 grown together at base: fr. purple, 3-celled, about Kin. 

 long. China. 



DDD. Styles villous at base: fr. subglobose. 

 E. Fls. white, the petals nearly orbicular and at base con- 

 tracted into a claw. 



33. Sargentii, Bean (Malus Sdrgentii, Rehd.). A 

 low bush, much branched, the branches rigid and often 

 spinescent: Ivs. ovate to elliptic-oblong or ovate- 

 oblong, about 2-3 in. long, sharply and unequally ser- 

 rate, slender-petioled, those on the vigorous branches 

 mostly ovate and 3-lobed: fls. pure white, 1 in. across, 

 in 5- or 6-fld. clusters, on glabrous pedicels about 1 in. 

 long; calyx-tube and lobes glabrous outside and villous 

 inside, the lobes ovate-lanceolate and acuminate; petals 

 about twice as long as calyx-lobes, oval, short-clawed, 

 glabrous; stamens 15-20; styles usually 4 (rarely 3 or 

 5), connate and villous below the middle: fr. subglo- 

 bose, Kin. or less diam., dark red with a slight bloom. 

 Japan. S.T.S. 1:37. G.C. III. 57:291 (as P. Malus 

 Sargentii); 58:309 (fr.). G.M. 58:278. 



EE. Fls. reddish (varying to nearly white), the petals 

 cuneate or rounded at base, obovate or oblong. 



34. Sieboldii, Regel (Mdlus Sieboldii, Rehd. Pyrus 

 Toringo, Sieb. M. Toringo, Sieb. P. Mengo, Sieb. M. 

 microcdrpa var. Torringo, Carr.) Fig. 3295. Shrub: 

 Ivs. ovate or oblong-ovate in outline, pubescent, becom- 

 ing colored in autumn, strongly notched or lobed 

 on either side at or below the middle, the middle lobe 

 often notched again near the top, the remaining mar- 

 gins sharply dentate: fls. small, blush, on slender sts.; 

 styles 3-4, connate at base; sepals triangular-ovate or 

 lanceolate, about equaling the tube: fr. the size of a 

 pea, shedding its calyx, yellow or red. Japan. R.H. 

 1870:451; 1881, p. 296. Gn. 34, p. 206. M.D.G. 1899: 

 456. Grown mostly for ornament, but lately recom- 

 mended as a hardy stock upon which to dwarf the 

 apple. In Japan, the little frs. are gathered after frost 

 and preserved. Upon the fr.-spurs, the Ivs. are some- 

 times only toothed, but upon barren or strong shoots 

 they are prominently lobed and suggest the Ivs. of 

 hawthorns. Var. arborescens, Bailey (Malus Sie- 

 boldii var. arborescens, Rehd.), which is widely dis- 

 tributed in Japan, differs from the type in its more tree- 

 like habit (to 30 ft.), less pubescent, Ivs. somewhat 

 larger and usually less deeply divided and often lobed 

 only on the ends of strong shoots, fls. often nearly 

 white, frs. yellow or red. Var. calocarpa, Bailey 

 (M . Sieboldii var. calocarpa, Rehd.), has large handsome 

 bright red fr. and large fls.: Ivs. on fruiting branches
