168 SELECT PLANTS FOR INDUSTRIAL CULTURE 



Nice about 180,000 Ibs. of jasmine flowers are produced annually 

 for distillation (Hegel). By Simmonnet/s process the essence of 

 jasmine is solidified as jasminin. 



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 ex- 

 pansion. 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 series are also deliciously fragrant, amongst which J. 

 lineare, Br., occurs in Victorian deserts; while also J. didymum, 

 Forst. ; J. racemosum, F. v. M. ; J. simplicifolium, Forst. ; J. cal- 

 careum, F. v. M. ; and J. suavissimum, Lindl., reach extra-tropical 

 latitudes. 



Jubaea spectabilis, Humboldt. 



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

 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 10 feet 

 long. Has endured at Montpellier of winter cold of +10 F. 

 (Osw. de Kerchove de Denterghem). Jubsea Torallyi ascends the 

 Andes to 8,530 feet. (De Kerchove). 



Juglans cinerea, Linne.* 



The Butternut Tree of North America. About 50 feet high ; stem- 

 diameter 4 feet. Growth of comparative celerity ; admits of trans- 

 plantation 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. Splendid 

 for select posts and rails needing durability ; it is soft, and there- 

 fore easily worked. This tree, with J. nigra endures still the severe 

 frosts of St. Petersburg, where the caryas can no longer be main- 

 tained. (Hegel). 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 importance, and so are those of other 

 species. 



Juglans cordiformis, Maximowicz. 



Japan. This species approaches in many respects J. Sieboldiana.
