IN EXTRA-TROPICAL COUNTRIES. 159 



principal species cultivated in South Europe for its scent. In 

 Cannes and Nice about 180,000 Ibs. of jasmin flowers are 

 produced annually for distillation (Regel). By Simmonnet's 

 process the essence of jasmin is solidified as jasminion. 



Jasminum Sambac, Aiton. 



From India to Japan. It has the richest perfume of all. The 

 bush attains a height of 20 feet, and is almost climbing. 

 The flowers are white, and must be collected in the evening 

 before expansion. The relative value of many other species of 

 jasmin, nearly all from the warmest parts of Asia, seems in 

 no instance to have been ascertained, so far as their oils or 

 scents are concerned. The Australian species are also deli- 

 ciously fragrant, amongst which J. lineare, Br., occurs in Vic- 

 torian deserts ; while also J. didymum, Forst. ; J. racemosum, 

 F. v. M. j J. simplicifolium, Forst. ; J. calcareum, F.v. M. 

 and J. suavissimum, Lindl., reach extra-tropical latitudes. 



Jubsea spectabilis, Humboldt. 



The tall and stout Coquito Palm of Chili, hardy still in Val- 

 divia. Well adapted for extra- tropical latitudes. A kind of 

 treacle is obtained from the sap of this Palm. A good tree 

 will give 90 gallons of mellaginous sap (C.Darwin). The 

 small kernels are edible. Stem to 60 feet, turgid towards the 

 middle ; leaves 1 feet long. 



Juglans cinerea, Linne.* 



The Butternut Tree of North America. About 50 feet 

 high ; stem-diameter 4 feet. Growth of comparative celerity ; 

 admits of transplantation readily. Likes rocky places in rich 

 forests, but is also content with poor soil. Wood lighter than 

 that of the Black Walnut, durable and free from attacks of 

 insects. It is particularly sought for furniture, panels of 

 coaches, corn-shovels, wooden dishes, and similar implements, 

 as it is not liable to split, nor heavy. The kernel of the nuts 

 is more oily than that of the ordinary walnut, taste similar to 

 Brazil nuts. The leaves, bark, and husk are of medicinal im- 

 portance, and so are those of other species. 



Juglans cordiformis, Maximo wicz. 



Japan. This species approaches in many respects J. Sie- 

 boldiana. 



Juglans Mandschurica, Maximowicz. 



Corea and Mandschuria. This Walnut is allied to J. cinerea 

 of North America.
