244 ANNALS OF SCOTTISH NATURAL HISTORY 



M. denticulata, Willd., and M. arabica, Huds., though both included 

 in the British flora, were more likely introduced from the 

 Continent, in fodder possibly. Both were rather plentiful in 

 1893 on some of the barer spots, but they did not reappear in 

 subsequent years. M. denticulata had formerly been found at 

 Aberdeen on ballast ; but M. arabica had not been observed 

 in the district before. M. lupulina, L., though not scarce near 

 Aberdeen in fields, strangely enough did not reappear after 

 1893 in the enclosed area. 



Trigonella polycerata, L., a native of South- West Europe, was repre- 

 sented by one example in 1893. It na d not previously been 

 found here. 



Mdilotus officinalis, Lam., probably introduced in fodder or with 

 agricultural seeds, has of late years been not an uncommon 

 casual around Aberdeen, especially where town-manure is 

 made use of. It is quite holding its ground as a denizen on 

 the reclaimed ground, rising conspicuously among the coarse 

 vegetation. 



M. alba, L., very scarce in 1893, became not uncommon in 1894 

 and 1895. This year I can find no trace of it. Its only 

 previous record from this district was from a field near Buckie 

 in 1890 (T. Edward). 



M. tndica, All., is also new among the casuals of North-East Scot- 

 land, but of it only a few plants occurred in 1893. They 

 flowered freely, but must have failed to perfect seed ; at least 

 the species has not reappeared. It is included as naturalised 

 in the " London Catalogue of British Plants." 



Trifolium hybriduiu, L. I refer to this clover, now so largely grown 

 as fodder throughout the country, only to note that in 1894 

 a considerable number of the plants showed anomalies in the 

 inflorescences. In some the pedicels were very long. In 

 others they were scattered some distance down the peduncle, 

 irregularly or in detached groups. In others the peduncle 

 ended in a vigorous leafy shoot or bore two or more secondary 

 heads on peduncles an inch or more in length. Usually these 

 abnormalities were associated with alterations in the floral 

 structure, the sepals being replaced by more or less perfect 

 leaflets, or, less often, by small bi- or tri-foliolate leaves. The 

 corolla was in some but little altered ; in others it was greenish 

 and more or less abortive. The stamens were often abortive. 

 The carpels were usually enlarged, in some projecting beyond 

 the corolla, and sterile, though closed ; in others varying in form 

 between the open carpel and the flat leaflet ; while in others 

 the carpel was replaced by a leaf of the ordinary structure, 

 though small. Similar abnormalities were met with, though in
