IN EXTRA-TROPICAL COUNTRIES. 167 



Jacaranda mimosifolia, Don. 



Brazil. This tree, with J. Braziliana and J. obtusifolia (Hum-. 

 boldt), furnishes a beautiful and fragrant kind of Palixander or 

 Palissandre wood, and so do probably some other tropical American 

 species. This wood is bluish red, traversed by blackish veins. J. 

 mimosifolia is hardy at Sydney, and thus may perhaps be reared 

 with advantage also in the warmer and moister regions of the 

 temperate zone. 



Jacks onia 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 amazingly. Several other Jacksonias share the importance 

 which this congener of theirs has acquired from its utility as a 

 pasture-bush. 



Jasminum grandiflorum, Linne". 



From India to Japan. Flowers white. Extensively cultivated 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 2| acres), which under very favourable 

 circumstances will 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 

 practised, 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 delicate scent is withdrawn either by fixed oils or alcoholic distilla- 

 tion. The pecuniary yield obtainable from Jasmin cultivation seems 

 vastly overrated, even if inexpensive labour should be obtainable. 



Jasminum odoratissimum, Linne. 



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

 foregoing and following for scent. This may be prepared by spread- 

 ing the flowers upon wool or cotton slightly saturated with olive 

 oil or other fixed oil, and covering them with other layers so pre- 

 pared. 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 thoroughly pervaded by the scent, when the latter is withdrawn by- 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 extracting the oil exist. 



Jasminum officinale, Linne. 



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

 species cultivated in South Europe for its scent. In Cannes and
