4. Zeyheri (P. Kochidnus, Koehne. P. coronarius Zey- 

 heri, Schrad.). Hybrid of uncertain origin, probably 

 between P. coronarius and P. inodorus. Lower than P. 

 coronarius: Ivs. variable, ovate to ovate-lanceolate, 

 acute to acuminate, with hard-tipped teeth, glabrous 

 or nearly so, or hairy along the veins beneath, those 

 of young succulent shoots and suckers ovate-lanceolate 

 to broadly ovate, sometimes with tufts of hairs on the 

 youngest, as in P. nepalensis: fls. white, slightly fragrant 

 or scentless. A puzzling shrub, at times confusingly 

 similar to P. coronarius. June. 



5. Lewisii, Pursh (P. columbianus, Koehne. P. 

 Gordonianus, Lindl. P. califdrnicus, Benth. P. cordi- 

 folius, Lange). Upright shrub, to 8 ft., very variable: 

 Ivs. about 1-3 in. long, most not more than 2H in., 

 about J^-2 (usually not more than \Y) in. wide: 

 racemes of varying length, generally but not always 

 leafy; fls. white, borne in great profusion, in wild plants 

 very fragrant, but, judging by some printed statements, 

 not always retaining the odor under cult. June, July. 

 Brit. Col. to Calif. B.R. 25:32. Excellent.- 



6. coronarius, Linn. (P. pdllidus, Hayek. P. coro- 

 narius nivdlis, Hort.). Figs. 2902, 2903. Shrub, to 

 10 ft.: Ivs. ovate-lanceolate (rarely ovate), generally 

 acuminate, usually rather evenly mucronate-denticu- 

 late (exceptionally almost entire), rarely slightly ser- 

 rate, thickish at maturity, about 1H-4 in. long, 

 Yr-IVi in- broad, slightly hairy beneath: fls. in rather 

 dense racemes, white or more often with a slight 

 creamy tone, very fragrant. May, June. Caucasus, 

 Armenia, and probably S. E. Eu. B.B. 2:186. F.E. 

 39:75 (habit). J.H. III. 70:471 This is the common 

 syringa, or mock orange, with less attractive foliage 

 than some, but the delicious fragrance unsurpassed. 

 The following horticultural and 2 wild varieties are 

 cult. Var. fldre-pleno, Hort. (P. coronarius dianthifld- 

 rus, rosseflbrus, and probably primulaeflorus and multi- 

 flbrus plenus, and other names), with more or less dou- 

 ble fls. Var. foliis argenteo-marginatis, Hort., Ivs. 

 white-margined. Var. foliis a&reis, Hort., lys. golden 

 yellow. Var. speciosissimus, Hort. (P. speciosissimus, 

 P. Zeyheri speciosissimus). Generally lower shrub than 

 the species, with rather uniform and smaller Ivs., 

 broadly ovate to rotund. Var. grandifldrus, Hort. (P. 



2903. Philadelphia coronarius. Mock orange. 



grandifloriis, Hort.), with larger fls. than in the species, 

 mostly 2 in. or more diam. Not to be confused with 

 P. inodorus var. grandiflorus, Gray, below. Var. salici- 

 folius, Hort. (P. salicifolius Hort., in part). Lvs. typi- 

 cally narrowly lanceolate, more or less willow-like, "but 

 sometimes, probably by reversion, broadly ovate, more 

 coarsely toothed. Var. nanus, Schrad. (P. ndnus, Hort. 

 P. salicifolius, Hort., in part), dense bushy plants, 

 usually not over \Y 2 ft. high; long cult, and known to 

 flower rarely. Var. acuminatus, A. H. Moore (P. acu- 

 minatus, Lange, P. satsiimi, P. satsumanus, P. yoko- 

 hama or yokohamse of cult.). Lvs. more acuminate 

 than in the species, the tips often bent to one side, 



especially in wild specimens, with conspicuous hard- 

 tipped teeth or serrations. Yunnan Province, China, 

 Japan, and Tsu Shima. Var. tomentosus, Hook. f. & 

 Thorns. (P. tomentosus, Wall. P. nepalensis, Lodd.). 

 Shrub, to about 6 ft. : Ivs. very hairy beneath. Hima- 

 layas and Thibet. Rather unattractive and of uncer- 

 tain hardiness. 



GG. The calyx tomentose. 



7. sericanthus, Koehne. Lvs. lanceolate, distantly 

 blunt-toothed or entire, mature ones about ljhr-4 in. 

 long, %-2 in. wide, glabrous beneath, or with few 

 scattered hairs: fls. about 5^in. across. June. Hupeh 

 Province, China. Larger-lvd. specimens have been 

 distinguished as var. Rehderianus, Koehne. 



8. incanus, Koehne. Lvs. ovate, more or less 

 abruptly acuminate, dentate, with 5 principal veins, 

 mature ones 13^-4/4 m - l n g> Y&&- across. June. 

 Hupeh and Szechuan provinces. China. 



FF. The Ivs. of young succulent shoots and suckers very 

 large, ovate-lanceolate to orbicular, very coarsely 

 toothed. 



9. floribundus (P. verrucbsus floribundus, P. grandi- 

 florus floribundus, Hort.). Hybrid of uncertain origin, 

 probably with P. coronarius as one parent. Shrub 

 resembling P. coronarius: Ivs. generally hairier than 

 in P. coronarius, and with characteristically very large, 

 ovate-lanceolate to more often orbicular, generally 

 coarsely toothed Ivs. on young succulent shoots and 

 suckers: fls. in racemes of about 5, about 2 in. across, 

 slightly fragrant. 



EE. Lvs. rarely over 1 % in. long (usually from about 



10. Lemdinei. Hybrid of P. coronarius and P. 

 microphyllus. Shrub with spreading branches, freely 

 flowering: twigs and little branchlets with short hairs: 

 ordinary mature Ivs. ovate to ovate-lanceolate, rather 

 uniform, rather small, glabrous or nearly so, acute to 

 acuminate, with a few minute teeth, those of the young 

 succulent shoots and suckers entire or remotely few- 

 toothed, somewhat larger: fls. 2-9, in dense racemes, 

 having a delicate but charming perfume. G.F. 2:617. 

 G.L. 28:225. The following horticultural varieties are 

 of interest: Var. erectus. Flowering branches irregularly 

 ascending, forming a more compact bush and less desir- 

 able. M.D.G. 1902:383. Avalanche. Graceful shrub, 

 taller than other varieties, branches sometimes as long 

 as 6 ft. : easily distinguished from the other varieties by 

 its lanceolate Ivs. G.C. III. 21:89. M.D.G. 1896:293; 

 1907:379. Bouquet Blanc. Lower If. -surfaces and 

 twigs with scattered hairs, distinctly visible : fls. in bou- 

 quet-like masses, not very fragrant. G.M. 55:487. 

 G.W. 17, p. 101. Candelabre. Very low shrub, ap- 

 proaching P. microphyllus in size, hairy as in the pre- 

 ceding, but with a more open candelabra-like infl. 

 M.D.G. 1896:294. Mont Blanc. Normally, probably, 

 the most profusely flowering variety, but very variable 

 in this respect. Hairs scarcely visible, a character at 

 once distinguishing it from all the preceding. Exceed- 

 ingly fragrant. Manteau d'Hermine. Twigs nearly or 

 quite glabrous. Pavilion Blanc. Profusely flowering 

 shrub: branches rounded or squarish in habit, twigs 

 hairy: Ivs. closely covered with silky hairs beneath. One 

 of the most beautiful, and the sweetest scented of all 

 the varieties, the perfume resembling that of P. micro- 

 phyllus. Gerbe de Neige. Calyx hairy. Boule d'Argent. 

 Fls. double, stamens mostly sterile, about 1*4 in. across, 

 not very sweet-scented; calyx glabrous. Oldest and 

 least desirable of double-fld. sorts. G.C. III. 18:18; 

 23:331. Virginal. Large double fragrant fls., 2H m - 

 across, or wider. G.M. 54:459. R.H. 1910, pp. 408, 

 409. Mer de Glace. Double fls., similar to preceding. 

 G.W. 17, p. 102. Var. fimbriatus is a distinct variety 

 with large fls., petals twisted and deeply serrate. For 

 other varieties of this hybrid consult list, p. 2582.
