484 Select Plants for Industrial Culture and 



affording a sweetish, food. In Afghanistan and countries near 

 thereto T. coloratns (C. A. Meyer) is used as Salsify [Dr. J. 

 Aitchison]. 



Trachylobium Hornemannianum, Hayne. 



Eastern tropical Africa. A large tree, content with sandy soil. 

 Thrives as far south as Natal [J. M. Wood]. Affords largely the 

 East-African Copal. T. verrucosum (Oliver) from Madagascar is 

 closely allied and serves the same purpose. 



Trapa bicornis, Linnefil.* 



The Leng, Ling or Links of China. The nuts of this water-plant 

 are extensively brought to market in that country. The horny 

 appendages of the fruit are blunt. The kernel, like that of the two 

 following species or varieties, is of an excellent taste. The plant 

 is regularly cultivated in the lakes and ponds of China. 



Trapa bispinosa, Roxburgh.* 



Middle and Southern Asia, where it is called " Singhara," 

 extending to Ceylon and Japan ; found also in Africa as far south 

 as the Zambesi. The nuts are often worked for starch. They can 

 be converted into most palatable cakes or porridge, and may be 

 stored for food, even for several years ; their taste is pleasant. 

 The produce is copious and quite maintained by spontaneous 

 dissemination. In some countries, for instance in Cashmere, the 

 nuts in a raw or cooked state form an important staple of food to 

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

 Chinensis (Loureiro) and T. incisa (Siebold and Zuccarini). 



Trapa natans, Linne.* 



The ordinary Waternut. Middle and Southern Europe, Middle 

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

 quadrispinosa (Roxburgh) from Sylhet, is a mere variety. Water- 

 fowl must be kept from places, where the Trapa is to prosper. 

 Fruits do not keep longer than one season, and must be preserved 

 in water [Yilmorin]. Mr. Hemsley has reduced all the Trapas to 

 one species, the intenability of the Eastern congeners having been 

 suspected before. Reproduction both by seeds and offshoots. 



Trexnella mesenterica, Retzius. 



From Europe to Australia. Arrayed by Dr. L. Planchon with 

 the fungs fit for human food. 



Trichodesma Zeylanicum, Brown. (Pollichia Zeylanica, F. v. M,) 



From Abyssinia and Southern Asia to extra-tropical Australia. 

 An annual herb, perhaps available for green manure. Dromedaries 

 show an extraordinary predilection for the herb [Giles]. Several 

 other species deserve trial for fodder-growth.
