FLORULA OF A PIECE OF WASTE GROUND AT ABERDEEN 243 



Galeopsis Tetrahit, L. Common on a limited area near the flour- 

 mills, along with other annual weeds. 



Lamium purpureum, L. Very scarce. 



Plantago major, Z., and P. lanceolata, Z., are diminishing in 

 frequency as the more open ground becomes more and more 

 restricted. 



Chenopodium album, Z., and var. viride, Syme, and Atriplex patula, 

 Z., not quite so abundant as in former years. 



Polygonum Convolvulus, Z., was common on rubbish along the 

 edge of the cinders, and occurred in small numbers here and 

 there on cinders ; but some rubbish heaps that were densely 

 covered with it in 1896 having been removed, it was much less 

 abundant on the whole this year than last. 



P. aviculare, Z., still common in the few open spots, but much less 

 general than formerly. 



P. Persicaria, Z. Much as in 1896. 



P. lapathifolium, Z. Only one or two plants seen in 1897, diminish- 

 ing in frequency. 



Rumex. The several species formerly enumerated by me showed 

 scarcely any change in relative frequency in 1897. 



Urtica dioica, Z. This nettle has spread little, but it forms two or 

 three pretty large scattered clumps. 



Carex ovalis, Good. A single plant sprung up and fruited on the 

 cinders, the only representative of the great order Cyperacese 

 that has been found here. 



Alopecurus geniculatus, Z. One or two small patches were 

 observed. 



Phleum pratense, Z., though by no means a common grass around 

 Aberdeen, has from 1893 been frequent on this waste ground. 

 It grows to a large size, and has continued to increase where 

 undisturbed, so that it now forms a very conspicuous part of 

 the coarse vegetation over much of the surface. 



Agrostis palustris, Ifuds., with var. stolonifera, and A. vulgaris With. 

 As in 1896. 



Deschampsia csespitosa, Beauv. A few vigorous tufts are scattered 

 over the area. 



Holcus lanatus, Z. As in 1896. 



Avena strigosa, Schreb., *A. fatua, Z., and A. sativa, L. These 

 occurred in small quantity on rubbish and on the more earthy 

 patches on the cinders, chiefly in the neighbourhood of the mills
