PYRUS 



2873 



cc. Calyx persistent on the Jr. 



D. Style glabrous at base: fr. punctate: Ivs. sharply and 

 mostly doubly serrate. 



25. Prartii, Hemsl. (Malus Prdttii, Schneid.). Young 

 growths whitish hairy but becoming glabrescent : Ivs. 

 3-4 in. long, the long petiole extra, ovate-lanceolate to 

 ovate or elliptic, acuminate-acute, the base usually 

 rounded, finely somewhat double-serrate with callous 

 serrations: fls. medium size, in many-fld. terminal sub- 

 sessile clusters, sjender-pedicelled ; calyx-lobes acumi- 

 nate, white-silky inside; petals ^jin. long, short-clawed, 

 rounded at apex, conspicuously veined; styles 5, gla- 

 brous: fr. about J^in. long, ovoid, punctate, the calyx 

 persistent. China. 



DD. Style rillous at base: fr. smooth and not punctate: 



Irs. simply serrate or crenate-serrate. 



E. Lvs. membranaceous or thin in texture, dutt above: 



calyx-lobes acuminate and longer than the tube. 



26. prunifdlia, Willd. (Malus prunifolia, Borkh. 

 M. hybrida, Loisel.). For years considered to be a 

 hybrid of P. baccata and P. Malus or other species, but 

 a plant which he considers to be a variety of it (var. 

 Rinki) having been found wild in China leads Rehder 

 to the conclusion that it is a good natural species; P. 

 prunifolia itself is yet known only as a cult, plant: tree,

 (XH). No. 26. 



glabrous or the pedicels and calyx more or less tomen- 

 tose: Ivs. much like those of P. baccata, but slightly 

 pubescent on veins below and glabrous at maturity: 

 small tree: Ivs. 2-3 in. long, ovate to obovate or nearly 

 orbicular, somewhat acute to short-acuminate, the 

 margin with small close somewhat unequal serratures: 

 fls. 6-10 in a sessile cluster, on pedicels 1-1 H in. long, 

 white, 1*2 in. across; calyx-tube obconical, the lobes or 

 sepals lanceolate; petals orbicular or oblong; styles 5, 

 connate below the middle: fr. about 1 in. diam., globose 

 to ovoid, with cavitv at base, green, yellow, or red. 

 Probably Siberia. B.M. 6158. 



Var. Rinki, Bailey (Malus pumila var. Rinki, 

 Koidz. M. prunifolia var. Rinki, Rehd. M. yezoensis, 

 Koidz. M. Matsumurse, Koidz. M. Ringo, Carr. 

 Pyrus Ringo, Wenz. P. prsecox, Miq.). CHINESE APPLE. 

 Figs. 3290, 3291. Wide-spreading small tree, to 15 

 or 18 ft. high, more pubescent than the type (P. 

 prunifolia) and representing a more southern range, the 

 petioles shorter and the fls. pink or pinkish rather than 

 white. China. B.M. 8265. This tree yields an edible 

 apple, sometimes as much as 1 }/i in. diam., of a greenish 

 or yellowish color and with a bitter-sweet flavor; it 

 was formerly grown in Japan for its fr., but its cult, 

 has been discontinued since the intro. of the European 

 apple, yet is now used as stocks for the imported kinds. 

 In China it is still sparingly cult. In botanical charac- 

 ters the plant is much like P. Malus, but is distinguished 

 by the much longer fr.-stalk, more sharply serrate and 

 usually less tomentose Ivs., the apex of the fr. not 



sunken but with a raised calyx which is thickened and 

 fleshy at the base. 



EE. Lvs. paper-like in texture, shining above: calyx-lobes 

 shorter than the tube or only equaling it. 



27. spectabilis, Ait. (Malus spectdbilis, Borkh. M. 

 sinensis, Dum.). CHINESE FLOWERING APPLE. Fig. 

 3292. Small tree, with 



darker - colored fls. 

 than those of the 

 apple (the opening 

 fl.-buds almost coral- 

 red), and blooming 

 earlier, making an 

 erect vase-like head: 

 Ivs. narrower, oval to 

 oval-oblong, slender- 

 stalked, nearly gla- 

 brous on both sur- 

 faces or becoming so, 

 usually more closely 

 serrate than those of 

 the apple: pedicels 

 and calyx-tube nearly 

 or quite glabrous: fr. 

 roundish or round- 

 oval, without a cavity 

 at the base, reddish 

 yellow, sour. Prob- 

 ably China and 

 Japan, although un- 

 known wild and very 

 little grown in those 

 countries although 



well known in cult, in Eu.; the plant called by this 

 name in Japan is probably P. Hattiana or P. microma- 

 lus. B.M. 267. L.B.C. 18:1729. Gn. 21, p. 46. Gng. 

 3:273. G.F. 1:272. A very handsome early- 

 blooming tree, of which the double-fld. and 

 semi-double forms are most prized. P. Malus 

 itself has been disseminated under the name of 

 P. spectabilis. Hardy in the northern states. Var. 

 Riversii, Booth, has very large half-double bright 

 rose-red fls. 



28. micromalus, Bailey (Malus micromalus, Makino. 

 M. spectdbilis var. micromalus, Koidz. Pyrus Kalda, 

 MouUl. Malus microcdrpa var. Kaido, Carr. M. spec- 

 tdbilis var. Kaido, Sieb.). Fig. 3293. Apparently a 

 hybrid, P. spectabilis being undoubtedly one of the 

 parents, and probably P. baccata or P. floribunda the 

 other. From P. spectabilis it is distinguished by the nar- 

 rower Ivs. which are gradually narrowed at the base 

 into a slender petiole, by tomentose pedicels and calyx, 

 and the subglobose fr. which has a depression at base 

 and apex, the calyx sometimes deciduous. Cult, in 

 Japan, and said to have been intro. from China;
