330 SELECT PLANTS FOR INDUSTRIAL CULTURE 



Dry timber very light, fine-grained, slightly more yellow than 

 that of the White Pine (P. J. White). It yields a red turpen- 

 tine (Hoopes). 



Touchardia latifolia, Gaudichaud. 



In the Hawaian Islands. A shrub allied to Boehmeria nivea, 

 yielding a tough and easily separable fibre, as first shown by 

 Dr. Hillebrand. Probably best adapted for humid warm 

 gullies. 



Tragopogon parvifolius, Linne. 



The Salsify. Middle and Southern Europe, Middle Asia. 

 Biennial. The root of this herb is well known as a useful 

 culinary vegetable. 



Trapa bicornis, Linne fil.* 



The Leng or Ling or Links of China. The nuts of this 

 water-plant are extensively brought to market in that country. 

 The horns of the fruit are blunt. The kernel, like that of the 

 two following species, is of an excellent taste. The plant is 

 regularly cultivated in lakes and ponds of China. 



Trapa bispinosa, Roxburgh.* 



Middle and South Asia, where it is called " Singhara," ex- 

 tending to Ceylon and Japan ; found also in Africa as far 

 south as the Zambesi. The nuts are often worked into starch ; 

 they can be converted into most palatable cakes or porridge, 

 They may be stored for food. The produce is copious and 

 cheaply maintained by spontaneous redissemination. It lasts 

 through several years. In some countries, for instance in 

 Cashmere, the nuts form an important staple of food to the 

 population. To this species probably belong T. Cochin Chin- 

 ensis (Lour.) and T. incisa (Sieb. and Zucc.). 



Trapa natans, 



The ordinary Waternut. Middle and South Europe, Middle 

 Asia, North and Central Africa. Recorded as an annual. T. 

 quadrispinosa (Roxb.), from Sylhet, is an allied plant. 



Trichodesma Zeylanicum, Brown. 



From Abyssinia and South Asia to extra-tropical Australia. 

 An annual herb, perhaps available for green manure. The 

 dromedaries show an extraordinary predilection for this herb 

 (Giles). Several other species deserve trial for fodder.
