Xos. 30 and (]8 give tubers among the longest which have been 

 cultivated: both ai)pear to be very good table yams, and both have 

 a tendency to produce twin tubers. ]S^os. 108 and 118 give tubers 

 somewhat more clavate. No. 118 having magenta sap, but not so 

 No. 108. No. 118 is certainly a good table yam. Both, and also 

 No. 54 have very delicate skins, which bruise easily. The shape 

 of the tuber of No. 54 is clumsy and so also is that of No. 186: 

 and both have been retained with some hesitation. 



It is well known that, for instance, there is no sale in many 

 markets for oversized lemons. So too many markets take up small 

 neat yams better than large yams : and with the intention of try- 

 ing to meet such a case it had seemed well to retain two races of 

 the Greater Yam which are noteworthy for tlie smallness, and 

 neatness of their tubers. Thev are : —

They are very unlike each other, and indeed have nothing in 

 common except shape. The ubi merah is well established in the 

 Malay Peninsula, and can easily be got in the Singapore markets. 

 Chinamen grow it al)Out Klang: and it has been seen on sale as 

 far away as Ran.goon, near which assuredly it is cultivated. It has 

 an extremelv delicate skin which is always bruised before it reaches 

 the market and then the intensely coloured sap below it is very 

 noticeable. Possibly the delicacy of its surface accounts for the 

 circumstance that in 1916 it was badly attacked by wliite ants iii 

 the yam beds in the Botanic Gardens. So far the impression is 

 that it is not a really good table yam. 



No. TO on the other hand has a firm surface, and keeps well 

 in store. It is altogether without magenta sap, and seems to be a 

 good table yam. In foliage if is quite unlike Xo. 6. 



Five lobulate yams have been kept in addition to the heavy 

 yielding races of tliat class, — Nos. 22, 50, 52, 64, GG and 192, also 

 one l)ranched yam in addition to the heavy yielding NTos. 44, 100 

 and 170. These six are, No. 98 being the l)ranched yam: —
