FLORULA OF A PIECE OF WASTE GROUND AT ABERDEEN 227 



find that Geranium molle, G. dissectum, Lotus tenuis, Potentilla 

 recta, Epilobium montamun, Carum Petroselinum, Scandix 

 Pecten- Veneris, Caucalis latifolia, Chrysanthemum Parthen- 

 iiiin, Helianthus tubcrosns, Lycopsis arvenszs, Mimulus lutens, 

 Lamium purpureum, and Carex ovalis have not been observed 

 in 1898. Of these, several were mere casuals, represented 

 only by one or two examples, while none were at all com- 

 mon. Several species were noted as diminishing in 

 frequency. 



On the other hand, some were evidently more abundant. 

 A few observed in the earlier years, but not in 1897, were 

 again found in 1898. These may have been due to casual 

 reintroduction by seed from the mills or brought in the 

 cinders, or some may have been undetected last year. The 

 species that recurred were : Lepidium Draba, Viola arvcnsis, 

 Silenc Cucubalus, Lotus uliginosus, Peucedanum sativum, 

 Chrysanthemum segetum, CicJiorium Intybus, Glyceria distans 

 (almost certainly present in 1897). 



The following were observed for the first time : Lotus 

 corniculatus, Arctinm intermedium, Polygonum cuspidatum 

 (all single plants), and Equisetum arvense. The single 

 example of Populus, though not mentioned previously, has 

 been some years on the ground. 



REPORT FOR 1899. 



THE foregoing report, written in September 1898, has 

 remained unpublished owing to want of room in this journal 

 during the past year ; but it appears better to allow it to 

 stand unchanged, and to confine the report for 1899 to 

 those features only of the locality and flora that show 

 conditions changed as compared with those of the previous 

 year. 



The railway lines have been increased in number ; and 

 both they and the cart tracks to (and in some parts 

 between) them now occupy much of the surface covered 

 with cinders. The latter area has also been extended in 

 some places ; and some of the plants previously observed 

 and recorded have been destroyed during the year. In two 

 or three places small rubbish-heaps have been deposited, on
