JASMINUM 



JASMINUM 



1 in. or less long: fls. pink or deep rose, verj' fragrant; 

 calyx-lobes linear, less than }4in. long; corolla-tube 

 short (less than J'2in. long); lobes of corolla erect or 

 spreading, broad-eUiptic or suborbicular, short. W. 

 China, altitude 8,000-9,000 ft. (Bees, Ltd., Liverpool.) 



AA. Lvs. of 3 or more Ifts. {sometimes only 1 in No. 19). 



B. The lvs. opposite. 



c. Fls. white. 



12. azoricum, Linn. CUmbing, glabrous or nearly so, 

 the branches terete: lvs. evergreen, opposite, the Ifts. 

 3, ovate-acuminate, the 2 side ones often smaller: calyx- 

 teeth very small; oblong eoroUa-lobes about as long as 

 the tube. Canary Isls. B.M. 1889.— A good white-fld. 

 temperate-house species blooming in summer and 

 winter. 



13. officinale, Linn. (J. poelicum, Hort.). Jessa- 

 mine. Fig. 2008. Long, slender grower requiring sup- 

 port, but scarcely self -climbing, glabrous or very nearly 

 so: lvs. opposite, odd-pinnate, the lateral Ifts. 2-3 pairs 

 and rhomboid-oblong-acute, the terminal one longer: 

 fls. white, 2-10 in terminal more or less leafy clusters; 

 calyx-teeth linear, J-^-Jli'n. long, or sometimes as long as 

 the rather short corolla-tube; coroUa-lobes 4 or 5, oblong, 

 more or less involute on the margins. Kashmir, 3,000- 

 9,000 ft., Persia, and now widely distributed. B.M. 31.

2008. Jasminum officinale. 



fragrant white summer-blooming fls. render the plant 

 very attractive in tlie S., where it is hardy. With pro- 

 tection it will stand as far N. as Philadelphia. Var. 

 affine, Nichols. (J. affme, Hort.), is a form with larger 

 fls. R.H. 1878, p. 428. There are double-fld. forms; 

 also with yellow- and silver-edged lvs. 



14. floribundum, R. Br. Much like J. officinale, but 

 differs in calyx-teeth, and corolla-lobes wider and more 

 obtuse and only half length of the tube: branches 

 glabrous: lvs. opposite; Ifts. 5, ovate, apiculate, the 



terminal one largest: fls. fragrant, white, in dichoto- 

 mous axillary and terminal clusters; calyx-lobes subu- 

 late, longer than the bell-shaped calyx-tube; corolla- 

 tube exceeding the calyx, to J-4in. long; segms. 5, J/2in- 

 long, oblong. Nile Land. 



1.5. angulare, Vahl. Climber with long 4-angled 

 branches: lvs. opposite, hirsute; Ifts. 3, orbicular, 

 ovate to lanceolate, mucronate: fls. white, about lj4in. 

 across, odorless, in 3's on axillary trifid peduncles; 

 calyx glabrous, 5-toothed, the teeth equaling or shorter 

 than the tube; corolla-tube many times longer than 

 calyx, 1-1} 2 in., very slender; lobes of corolla 5-7, 

 oval-lancoolate, somewhat obtuse or subacute. S. Afr. 

 B.M. 6865. G.C. III. 28:360, 361. Var. glabratum, 

 Mey. {J. capense, Thunb.). St. scarcely puberulent, 

 the lvs. glabrous. 



16. grandifionim, Linn. Catalonian, Italian, 

 Royal or Spanish Jasmine. Nearly erect-growing, the 

 branches drooping and angular, glabrous or very nearly 

 so: lvs. opposite, the rachis flattened or winged, the Ifts. 

 5-7, eUiptic or round-eUiptic or oval, mostly ending in a 

 very small point or cusp, the terminal 1ft. mostly ovate- 

 lanceolate and acuminate: calyx-teeth Jiin. long or 

 rarely half as long as the corolla-tube; corolla star- 

 shaped, larger than in J. officinale. India; naturalized 

 in Fla. B.R. 91. G. 2:451.— Probably the best white- 

 fld. species. Summer and faU, or nearly perpetual in 

 warm countries. Much grown in Eu. for perfumery, 

 and also a good greenhouse subject; young stock may 

 be planted out in spring; will stand sun. Stands 10-12° 

 of frost. 



cc. Fls. yellow. 



17. nudifldrum, Lindl. (J. Sieboldidnum, Blume). 

 Twiggy nearly erect shrub with 4-angled glabrous stiff 

 branchlets: lvs. opposite, small, with 3 little ovate cili- 

 ate Ifts., the entire foliage falling in autumn or when 

 the growth is completed: fls. sohtary, in early spring (or 

 winter), from long, scaly buds, subtended by several or 

 many small If .-like bracts, yellow; caljTi-lobes leafy 

 and spreading or reflexed, shorter than the corolla- 

 tube; corolla-segms. obovate, often wavj'. China.

 11:181. G.W. 15, p. 300. H.F.2:64. J.F.3:320. Var. 

 afireum, Hort., has yellow-variegated foliage. — A 

 most interesting species, reminding one of forsythia 

 when in bloom. Hardy south of Washington, and 

 blooming nearly all winter. With protection, it will 

 stand as far north as Hudson River valley, and bloom 

 very early in spring. In northern glasshouses, used 

 mostly as a late winter and early spring bloomer. 

 Strong-growing specimens need support. 



18. primulinum, Hemsl. Very like J. nudiflorwn, 

 botanically, but with larger lvs. which are sometimes 

 well developed at flowering-time, and with much larger 

 fls., the limb of the corolla exceeding the tube; a ram- 

 bhng very free-flowering evergreen glabrous shrub, with 

 slender green 4-angled branches: lvs. petioled, of 3 Ifts. 

 which are almost sessile and 1 or 2 in. long, entire, 

 oblong-lanceolate, shining above and paler beneath: 

 fls. primrose-yellow with a darker eye, 1 J 2-2 in. across, 

 solitary on axillary bracted peduncles or branchlets; 

 calyx-lobes lanceolate, slightly hairy; coroUa-lobea 

 usually 6, obovate-spatulate ; stamens exserted. Yun- 

 nan, China, apparently as an escape from cult.; some- 

 times partially double". B.M. 7981. G.C. III. 33:197.

 F.S.R. 2:168. — One of the best introductions of 

 recent years; stands some frost. It blooms in early 

 spring, the season lasting two months or more. Not 

 hardy north of Washington, but nearly evergreen in 

 the S. 



BB. The lvs. alternate: fls. yellow.

 Boiss. & Gaill.). Glabrous bush, to 12 ft., not climbing,
