VASCULAR CRYPTOGAMS. 



Lycopodium Selago, L., near Selby, W. N. Cheesman. k rather 

 interesting discovery in such a locality, the altitude being only 

 about 20 feet. Mr. Cheesman writes : — " I found it last autumn, 

 growing in a railway delving about a mile from the town at 

 the extreme border of the West Riding. I am not aware of its 

 occurrence an}^here in the district. The plants numbering about 

 20 or 30, were growing in a patch of rather elevated sandy soil in 

 the cutting, the subsoil of which had been thrown up for the railway 

 embankment. The lycopod was fruiting freely, and seemed as much 

 at home as some I had observed a few weeks before on Ingle- 

 borough. * * * I should like to know how it is that L. Selago has 

 sprung up in this place. Is this plant another ^ relic of a boreal 

 age,' and have the spores lain dormant in the ground during the 

 ages that have passed since the last glacial period, and become 

 quickened into life through the sun's influence on the removal of 

 the two or three feet of soil from the present ground Mr. Chees- 

 man then invites opinions on this occurrence. 



Chara foetida, Braun. Bog near Malham Tarn, W. West. 

 C. hispida, Ij. Askern, H. T. Soppitt and P. F. Lee.
