 Received May 7, 1923. 



A perennial prostrate clover with oval leaflets and 

 roundish heads of pink flowers which open in July 

 and August. Native to southeastern Europe. In 

 the flowering stage this species resembles white 

 clover, but it does not creep. (Adapted from Ascher- 

 son und Graebner, Synopsis der Mitteleuropdischen 

 Flora, vol. 6, pt. 2, p. 525.)

57036. Tbifolium pbatense L. Fa- 

 bacese. ' Red clover 



From Copenhagen, Denmark. Seeds presented 

 by H. N. Knudsen, Danish Royal Agricul 

 tural Society. Received May 7, 1923. 



Tystofte No. Jfi originated in a 2-year plat of Rozen 

 daal clover. Seed of this variety was sown in 1900, 

 and the clover was thus subjected to the hard winter 

 of 1901. In 1902 the strongest plants from this test 

 were selected, one of which was No. 40. Later this 

 strain was compared with others in several tests 

 In three of four tests all the clovers made vigorous 

 growth during the first year, and in this respect No 

 40 averaged well above the others. In all four tests 

 No. 40 gave the largest crop, fully 20 per cent better 

 than that of the next best. These results agree well 

 with the results of earlier tests at Lyngby and Tys 

 tofte, in which this strain decidedly surpassed all 

 others. (Adapted from Beretning fra Statens For 

 sogsvirksomlied i PlanteUultur, No. 95, p. 401.)

 black barley from Biskra. The Arabs 

 tell me that before the big famine of 20'

 barley was often grown. The few seeds 

 under this number were found by pick- 

 ing over many samples in the market .. 

 They may be from widely separated 

 points."
