158 SELECT PLANTS FOR INDTJSTUIAL CULTURE 



(Humboldt), furnishes a beautiful, and fragrant kind of Palix- 

 ander or Palissandre wood, and so do probably some other - 

 tropical American species. This wood is bluish red, traversed 

 by blackish veins. /. mimosifoUa is hardy at Sydney, and 

 thus may perhaps be reared with advantage also in the warmer 

 and moister regions of the temperate zone. 



Jacksonia cupulifera, Meissner. 



West Australia. It might prove an advantage to disseminate 

 this small tree in arid desert regions, as horses and cattle relish 

 the foliage a,mazingly. Several other Jacksonias share the 

 importance which this congener of theirs has acquired from its 

 utility as a pasture-bush. 



Jasmiuum graudiflorum, Linne. 



From India to Japan. Flowers white. Extensively culti- 

 vated in South Europe. It is planted in rows 3 feet apart, 

 the plants at a distance of 2 to 3 inches in the rows. Leek, 

 tuberoses, and similar plants are used to occupy the spare 

 ground for the first year ; 1,000 plants in the second year after 

 grafting produce 50 kilos (about 1 cwt.) of flowers in rich soil. 

 Five thousand kilos can be produced on an hectare (nearly %\ 

 acres), which under very favourable circumstances wiU realise a 

 profit of 5,800 francs per annum. Against frost and exposure 

 to wind the plants must be guarded (Deherain). In France it 

 is generally grafted on J. officinale. The bushes are richly 

 manured and well watered. Ordinary cleft-grafting is prac- 

 tised, the stock being headed down to near the ground. A 

 good workman and assistant will graft about 1,000 plants in 

 a day. The delicate scent is withdrawn either by fixed oils or 

 alcoholic distillation. The pecuniary yield obtainable from 

 Jasmin cultivation seems vastly overrated, even if inexpensive 

 •labour should be obtainable. 



Jasmiuum odoratissimum, Linne. 



Madeira. Shrubby like the rest. Flowers yellow. Used like 

 the foregoing and following for scent. This may be prepared 

 by spreading the flowers upon wool or cotton slightly satur- 

 ated with oHve oil or other fixed oil, and covering them with 

 other layers so prepared. The flowers are renewed from time 

 to time until the oil is thoroughly pervaded by the scent, when 

 the latter is withdrawn by alcohol. Other modes of extract- 

 ing the oil exist. 



Jasminum officinale, Linne. 



From the Caucasus to China. Flowers white. This is the
