JASMINUM 



easy culture. They propagate readily by cuttings of 

 nearly mature wood and by layers. Often the fls. 

 are very fragrant. The species are usually culled Jas- 

 mines, aTid the word Jessamine is commonly restricted 

 to J', officinale, which is the Jessamine of poetry. Some 

 of thera (particularly J. graudifloritm) are grown for 

 perfume-making. The Cape Jessamine is Gardenia. Yel- 

 low or Carolina Jessamine is Gelsemium.

A. Lvs. reduced to one Ift,: fls. white. 



B. Calyx pubescent or hairy, 



1. Sambac, Soland. Arabian Jasmine. Climbing, 

 the angular brauchlets pubescent: lvs. opposite or ter- 

 nate (the ternate-lvd. specimens giving rise to the name 

 trifoliatum), firm in texture, shining, nearly or quite 

 glabrous, the petiole short and abruptly curved upwards, 

 elliptic-ovate or broad-ovate, either prominently acute 

 or completely rounded on the end, entire, prominently 

 veined: clusters 3-12-fld. : calyx lobes linear and promi- 

 nent, hirsute on the edges (sometimes almost glabrous) : 

 corolla tube y^ in. long; lobes oblong or orbicular. 

 India. — Much cult, in the tropics. Fls. white, but turn- 

 ing purple as they die. B.B. 1:1. A full double but- 

 ton-fld. group is in cult., one form of which is the Grand 

 Duke of Tuscany (or Grand Duke). The double form is 

 shown in B.M. 1785. This double form sometimes passes 

 as J. trifoliatum. J. Sambac is a perpetual bloomer, 

 particularly in t'rostless countries, where it can stand 

 in the open. 



2. unduliltum, Ker. Climbing, with hairy branches, 

 slender : lvs. o[)posite, short-petioled, rather small 

 (about 2 in. long), ovate-lanceolate and acuminate, some- 

 what pubescent beneath, somewhat undulate: fls. 6-10, 

 in terminal cymes, white, long-tubed; calyx teeth short; 

 corolla tube % in. long, and slender; lobes half or less 

 as long, acute. India. B.R. 6:4.'!6. — Lvs. sometimes ter- 

 nate. Little known in cult, in this country. 



3. pub^scens, Willd. (J. hir.^utum,Wi\]d. J. multi- 

 /Idrum, Andr.). Climbing, rusty-hairy: lvs. very short- 

 petioled, rather thick, ovate-acute: calyx teeth usually 

 % in. long (nearly or quite twice as long as in J", undu- 

 latum), with spreading yellow hairs: fls. white, much 

 like those of ./. undulatum, the lobes broad, often half- 

 double. India. B.M. 1991. B.R. 1:15. -Will stand some 

 frost. 



4. gTacillimum, Hook. f. Climbing or scrambling, soft 

 pubescent or hairy: lvs. very short-petioled, ovate-lan- 

 ceolate, acuminate, the base cordate or truncate, bright 

 green above and pubescent bene.ath, 1% in. or less long: 

 fls. white, in very large, dense hanging heads, an inch 

 or more across, fragrant; calyx teeth long and awl-like, 

 half as long as the slender corolla tube; corolla lobes 

 many (usuallyabout 9), acute. N.Borneo. G.C.II.15:9. 

 B.M. (5559. — Long, lithe branches spring from near the 

 ground and bear heavy clusters at their ends. Handsome 

 winter bloomer. Nearly hardy in eastern N. Car. 



BB. Calyx glabrous. 



5. trinerve, Vahl. Tall-climbing, with terete glabrous 

 branches: lvs. short-stalked, ample, ovate-oblong and 

 acuminate, strongly 3-nerved from the base: fls. white, 

 \a small clusters; calyx teeth narrow but much shorter 

 than the long corolla tube; corolla lobes only half as 

 long as the tube, acute. India. B.R. 11:918. — Perhaps 

 only a form of J. anastomosans. Wall. 



6. simplicifdlium, Porst. (J. lucidum. Banks). 

 Climber, or sometimes a tree in its native place, gla- 

 brous or pubescent: lvs. mostly short-stalked, shining, 

 varying from oblong-elliptic to ovate-lanceolate to cor- 

 date-ovate, acute or obtuse, usually less than 3 in. long: 

 fls. white, in terminal forking, many-fld. clusters; calyx 

 teeth short and sometimes scarcely any; corolla tube

 Summer bloomer. 



AA. Lrs. of S or more Ifts. 

 B. Flowers white. 



7. officinale, Linn. (J. poUicum, Hort.). Jessamine. 

 Long, slender glower requiring support, but scarcely 

 self-climbing, glabrous or very nearly so: lvs. opposite, 

 odd-pinnate, the lateral Ifts. 2-3 pairs and rhomboid-ob- 

 long-acute, the terminal one longer: fls. 2-10 in termi- 

 nal more or less leafy clusters; calyx teeth linear, 

 }4--a in. long, or sometimes as long as the rather short 

 corolla tube; corolla lobes oblong, more or less involute 

 on the margins. Persia, India. B.M. 31. B.H. 1878, p. 

 428. — Long cultivated. The glossy foliage and fragrant 

 white summer-blooming fls. render the plant very at- 

 tractive in the S., where it is hardy. With protection it 

 will stand as far N. as Phila. Var. affine, Nichols. (J. 

 affUie, Hort.), is a form with larger fls. R.H. 1878, p. 

 428. 



8. grandifldrum, 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. 2-3 

 pairs, elliptic or round-elliptic, mostly ending in a very 

 small point or cusp: calyx teeth )4in. long or rarely 

 half as long as the corolla tube; corolla star-shaped, 

 larger than in J. officinale. India. B.R. 2:91. — Prob- 

 ably the best white-flowered species. Summer and fall, 

 or nearly perpetual in warm countries. Much grown in 

 Eu. for perfumery. Stands 10°- 12° of frost. 



9. Azdricum, Linn. Climbing, 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 corolla lobes about as long as 

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

 temperate-house spei-ies blooming in summer and winter. 



BB. Flowers yellow, 



10. himile, Linn. (J. revolidum, Sims. J. flAvum, 

 Sieb. J. triiimpkans, Hort.). Italian Yellow Jas- 

 mine. Fig. 1191. A diffuse shrub, in the open ground 

 in the S. reaching 20 ft. and requiring support, but in 

 glasshouses usually grown as a pot bush : branches gla- 

 brous, angled: lvs. alternate, odd-pinnate (rarely re- 

 duced to 1 1ft.), the lateral Ifts. 1-3 pairs, all Ifts. thick- 

 ish and acuminate, and more or less revolute on the edges, 

 varying from oblong to oblong-lanceolate to oblong-ro- 

 tund: fls. bright yellow, in open clusters; calyxteethvery 

 short; corolla tube %-l in. long, usually considerably 

 exceeding the mostly obtuse and reflexing lobes. Trop. 

 Asia. B.M. 1731. B.R. 3:178; 5:350. L.B.C. 10:966.- 

 The commonest Jasmine in American glasshouses, usu- 

 ally known as J. revolutum. It is hardy in the open as 

 far north as Maryland. Lvs. thick and evergreen. Needs 

 a cool house if grown under glass. Summer and fall 

 bloomer. J. Seevesii, Hort., may belong to this species. 



11. odoratissimum, Linn. Much like the last, but more 

 erect and less leafy when in flower: lvs. alternate, the 

 leaflets 3 or 5. shining, oval or broad-oval and obtuse: 

 fls. yellow, in a terminal cluster; calyx teeth very short; 

 corolla lobes oblong-obtuse, mostly shorter than the tube.
