It will be noticed that the indigenous plants were on the 

 average very decidedly more leafy* than the foreign, and also 

 appeared to possess the abilitv of greater tiller production. Of 

 the twenty-four lots only one indigenous bed gave less than 

 30 per cent, leaf, and only one foreign (Be. 13 Danish) gave 

 over 30 per cent. leaf. Selected clumps put out in spaced rows 

 showed similar results,! the foreign giving an average leafi- 

 ness of 38 per cent, and the indigenous 49 per cent. 

 Plate VIII shows the average difference in leafiness between 

 an indigenous (Be. 115) and commercial Danish (Be. 75) 

 clump, t 



In the matter of lateness, also, the advantage was entirely 

 with the indigenous plants. This was confirmed by the 

 behaviour of the selections, only one or two clumps being as 



* The leaves were cut off from the stem at the ligule, so that, strictly- 

 speaking, " leaf " as here understood means the lamina only, and not lamina 

 and sheath. 



t Transplanting appears on all occasions to add to the relative lealiness 

 of grasses. 



X It cannot be asserted with certainty that the " plants " in each pot 

 are definitely single plants, although when dug up from the beds in which 

 they were sown and put out in "selection rows" they were thought to be 

 so. They were only potted for the purpose of being photographed.
