in the distribution of the three species, many of vvhich would be ob-

rarest species (T. SerpyLLum) was indicated.

Photogr.\phs of ACTAEA SPICATA L. in Britain and Sweden 
This species is probably best known in Britain growing in the crevices 
of the Carboniferous Limestone ‘ i)avements”. This type of habitat 
was illustrated by a photograph taken at Malham, Yorks. A more , 
typical Continental habitat was shown in the second photograph, where 
Actaea formed a part of the field layer in the rich spruce forest on 
Omberg, Sweden. Here it was associated with a woodland flora, in- 
cluding, inter alia, Acer platanoides L., Anemone Uepatica L., A. 
nemorosa L., A. ranuncul aides L., Dentaria hulhifera L., Ilieraciuni 
sp., Lonicera Xylosteum L., Oxalis Acetosella L., Paris quadrifoUa L., 
Sorhus aucuparia L. and Viola sp. Maps showing the distribution of 
Actaea spicata in Britain and Scandinavia were also exhibited.
