easy culture. They propagate readily ])y cuttings of 

 nearly mature wood and by layers. Often the fls. 

 are very fragrant. The species are usually called Jas- 

 mines, and the word Jessamine is commonly restricted 

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

 of them (particularly J. gnindifloriini.) are grown for 

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

 low or L'arf'lina Jessamine is Gelsemium.

 the angular branchlets pubescent: Ivs. opposite or ter- 

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

 iril'olliiliim), tirm in texture, shining, nearly or quite 

 glabrous, the petiole short and abruptly curved upwards, 

 elliptic-ovate or broad-ovate, either prominently acute 

 or completely rotinded on the end, entire, prominently 

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

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

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

 tou-Hd. 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. 178.5. This double form sometimes passes 

 as J. trifoliatiiiii. J. Samhiie is a perpetual bloomer, 

 particularly in frostless countries, where it can stand 

 in the (.'pen.

 frost. 



i. gracillimuni.Hook.f. Climbing or scrambling, soft

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

 half as long as the slender corolla tube; corolla lobes 

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

5. trln^rve, Vahl. Tall-climbing, with terete glabrous 

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

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

 in small clusters; calyx teeth narrow but much shorter 

 than the long corolla tube; corolla lobes only half as

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

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

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

 Long, sleiuler grower requiring support, but scarcely 

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

 long-acute, the terminal one longer: tis. 2-10 in teruii- 

 mil more or less leafy clusters; calyx teeth linear,

 corolla tube; corolla lottes oblong, more or less involute 

 on the margins. Persia, India. B.M. 31. K.H. 1878, i'.

 \\'hite suuimer-blooming Hs. render the plant very at- 

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

 or nearly perpetual in warm countries. I\Inch grown in

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

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

 a cool house if'gruwn under glass. Summer and fall 

 bloomer. J. JfccVi xii, Hort.. may belong to this species.

 erect and less leafy when in Hower: lvs. alternate, th.- 

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