 „ not flattened . . . • Nos. 76, 128, 192. 



It may be noted that the races with flattened tubers which 

 yield heavily, are in all cases either lobed or branched : 



And again it may be noted that none of the long deep going 

 yams are among these races. 



In foliage the above eleven varied greatly. No. 76 has a 

 prickly stem. 



No 50 is a yam that has been cultivated for three seasons in 

 the garden of Mr. G. P. Owen, in Singapore ; and in the first of 

 them he obtained a tuber weighing 26 lbs. He gave sets irom it 

 to Mr W E. Hooper who obtained a still larger tuber with a 

 girth of 52 inches and also to Dr. W. F. Samuels who at Tanjong 

 Rambutan, Perak, also got large tubers. 



It is believed that the following promise a yield of more than 

 the average, but did not give it because of some mischance : there- 

 fore they have been retained as if heavy yielders along with tliose 

 enumerated alcove. The mischance is the case of No. 102 was due 

 to the necessitv of interrupting the growth of the tubers, m the 

 first season of trial before their time was complete, in order to bring 

 them into the same period of growth as the others; and m the 

 case of No. 10 the mischance arose from thefts : m the case ot all 

 the other, the start in 1916 was with undersized sets.
