534 Select Plants for Industrial Culture and 



Trapa bispinosa, Roxburgh.* 



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

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

 Zambesi. The nuts are often worked for starch. They can be con- 

 verted 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, Linn&* 



The ordinary Waternut. Middle and Southern Europe, Middle 

 Asia, Northern and Central Africa. Formerly it extended much 

 further northward in Europe than now. 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 

 [Vilmorin]. 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. 



Tremella mesenterica, Retzius. 



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

 the fungs fit for human food. Dr. Cooke mentions also as edible T. 

 lutescens, Pers., which extends to the colony of Victoria. 



Trichostema lanatum ; Bentham. 



California, where it is called the "Black Sage." A half-shrub, 

 recorded by Mr. A. J. Cook in the " Bee-keepers' Guide " among 

 important honey-plants. 



Trifolimn agrarium, Dodoens. (T. aureum, Pollich.) 



The Perennial Yellow Clover or Hop-Clover. All Europe* 

 Northern Africa, Western Asia ; wild in Norway northward to lat. 

 63 26' [Schuebeler] , extends indigenously to Abyssinia. It has 

 the merit of being comparatively large among the common yellow 

 clovers. Slightly cumarin-scented. Of considerable value in sandy 

 soil as a fodder-herb. It is easily naturalised. 



Trifolium Alexandrinum, Lhm6.* 



The Bersin-Clover. North-Eastern Africa, South- Western Asia, 

 South-Europe. Much grown for forage in Egypt, where it is used 

 as the main-fodder. On the Nile it gives three green crops during 

 the season, each up to 2 feet high. Seeds of this and other clovers 

 must be sifted, to free them from any of the destructive Dodder- 

 plants or Cuscutas. About 20 Ibs. of seed are required for an acre 

 [Morton]. Recorded as annual.
