PYRUS 



PYRUS

mostly ovate-oblong and crenate-serrulate, those on 

 the vigorous shoots mostly 3-lobed with the lateral 

 lobes short and broad: distinguished from P. Zumi by 

 the 3-4 rather than 4-5 styles and by the lobed Ivs. 



35. Zilmi, Mats. (Mains Ziimi, Rehd.). Low and 

 much-branched tree, to 20 ft., with rounded head and 

 twiggy growth, sometimes 40 ft. tall and with more 

 ascending branches: Ivs. long-petioled, oblong to ovate- 

 oblong or elliptic-oblong, l%-3 in. long, acute at apex, 

 rounded or narrowed at base, entire or somewhat cre- 

 nate-serrate, yellowish green above and light green 

 beneath, soon glabrous, those on the ends of vigorous 

 branches lanceolate and usually coarsely dentate: fls. 

 white or slightly pinkish, borne in profusion, about 1 in. 

 across, on loosely villous or glabrous pedicels about 1 

 in. long; calyx-lobes lanceolate, villous inside and less 

 so outside; petals elliptic, obtuse, rounded at base but 

 short-clawed, opening pink but becoming pure white; 

 stamens about 25; styles 4 or 5, connate for one-third 

 their length, densely villous: fr. Kin. or less diam., glo- 

 bose, red, the calyx deciduous. Mountains of Cent 

 Japan. S.T.S. 1:91. Differs from both P. Sargentii 

 and P. Sieboldii in the oblong Ivs. which are not at all 

 or only slightly lobed, and slender petioles; from P. 

 Sargentii also in longer petals rounded at base, glabrous 

 Ivs., longer petioles, and erect branches; from P. 

 Sieboldii also in differences in foliage, larger fls., larger 

 broader petals rounded at base. 



36. pulcherrima, Aschers. & Graebn. (P. flori- 

 bunda, Kirchn., not Lindl. P. Mains floribunda, Hort. 

 Malus floribunda, Sieb. M. microcdrpa var. floribunda. 

 Carr.). FLOWERING CRAB. Unknown in the wild but 

 long in cult., and perhaps a hybrid of P. baccata and P. 

 Sieboldii; intro. from Japan, where it seems not to be 

 recognized, Rehder finding that what the Japanese 

 botanists know under this name is P. Hattiana: shrub 

 or sometimes a small tree, often thorny: young growths 

 glabrous or very soon becoming so: Ivs. ovate and 

 usually acuminate, the petioles rather thick and red- 

 dish and usually not much if any more than 1 in. long 

 on the leading young shoots, the margins very sharply 

 serrate or incised-serrate, not lobed, usually" thickish, 

 shining above and glabrous (or soon becoming so) 

 beneath: fls. rose or rose-red, appearing with the Ivs., 

 produced in great abundance and very showy; styles 

 nearly always 4. very rarely 3 or 5, connate to the mid- 

 dle: fr. usually about the size of a pea, on long, slender 

 stalks, red, not persisting till winter. China. R.H.

 M.D.G. 1899:454. The name of this species is some- 

 what in confusion. It has been known as P. floribunda, 

 but Lindley earlier gave this name to a very different 

 plant, of the section or genus Aronia (see p. 396, Vol. 

 I), and the present species must take a new name. P. 

 pulcherrima is one of the best of all early spring-flow- 

 ering bushes or small trees, and is now common in gar- 

 dens. The semi-double forms often improperly receive 

 the names Halliana and Parkmanii. It makes a broad 

 round-headed great bush, with handsome rose-colored 

 buds and whitish expanded fls. P. atrosanguinea, 

 Spaeth, is a handsome floriferous species of doubtful 

 origin. It is probably P. HaUiana x P. Sieboldii 

 (Koehne supposes it to be P. Halliana x P. fusca) : 

 resembles in general P. pulcherrima, but differs in its 

 deep carmine fls. not fading to white, rather narrower 

 petals, shorter ovate and somewhat obtuse calyx-lobes, 

 more shining and finally glabrous Ivs., those Ivs. at the 

 end of vigorous shoots sometimes slightly 3-lobed: fr. 

 dark red. Gt. 47:1448. 



Var. Scheideckeri, Bailey (Pyrus Scheideckeri, Spaeth. 

 Malus Scheideckeri, Zabel), originated at Scheidecker's 

 nursery at Munich from seeds of P. pulcherrima, but 

 shows evidences of hybridity with some closely related 

 species (probably with P. prunifolia) or else indicating 



the hybrid origin of P. pulcherrima itself : small tree of 

 pyramidal habit, producing abundantly of large semi- 

 double tinged pink fls.: young branchlets slightly 

 pubescent: Ivs. ovate, acuminate, about 3 in. long, scat- 

 tered-pubescent beneath, petiole hairy, margins coarsely 

 sharp-serrate or double-serrate: fr. globose, %in. diam., 

 the calyx usually persistent. Gng. 6:308. A.F. 13:

Var. Arnoldiana, Bailey (Malus floribunda var. Ar- 

 noldiana, Rehd.). Originated at the Arnold Arbore- 

 tum, Boston, as a seedling of P. pulcherrima: fls. more 

 than one-half larger than in the type, pale rose: fr. 

 much larger, yellow: of bushy habit. 



3295. Pyrns Sieboldii (XM). See No. 34. 



AAA. The American native wild apples or crabs, some- 

 times planted in grounds but only P. ioensis 

 yielding marked horticultural forms: fls. large, 

 pink, fragrant: Ivs. for the most part coarsely 

 toothed and more or less lobed or notched: calyx 

 persistent (exception in P. fusca). Not all these 

 species are in cult, outside botanical collections, 

 but they have been so much confused that it is 

 necessary to describe all of them in order clearly to 

 distinguish them. 



B. Calyx deciduous from thefr.: western. 

 37. fusca, Raf . (P. rivularis, Douglas. Malus rivularis, 

 Roem.). Shrub or small tree, sometimes 30-40 ft. tall, 

 the young growths more or less pubescent: Ivs. ovate- 

 lanceolate, acute or acuminate, very sharply and 

 strongly serrate, often 3-lobed or notched on the strong 

 shoots, pubescent beneath: fls. white, on slender pubes- 

 cent pedicels, appearing when the Ivs. are nearly or 

 quite full grown, nearly or fully 1 in. across: fr. oblong, 

 %in. or less long, yellow or greenish, the calyx-lobes 

 caducous. N. Calif, to Alaska. S.S. 4:170. Accord-
