curved (sometimes very strongly so). Tec^th of the inner peristome 

 minutely ])unctate. Antheridia usually in separate gemmiform 

 groups. Leaves often less llexuose and shorter. 



In Septemher 1921 1 found the same plant on the Yorkshire side 

 at a much lower altitude, ahout 1000 ft. It occurred on the vertical 

 faces of millstone grit boulders which were surmounted by peat. 

 Though I had previously'" passed this spot scores ot" times, I had 

 never noticed the moss with capsules, and had regarded it as a barren 

 Dicranella. It is })robable that the remarkably clear weather of 

 1921, coupled with the fact that, owing to the coal strike, the atmo- 

 sphere was freer from smoke, enabled capsules to be formed. The 

 plant is probably fairly common on the millstone grits of the Pennines,. 

 but has been overlooked because of its general barrenness and its* 

 resemblance to a Dicranella. 



FURTHER NOTES ON ELM FLOWERING. 

 By Eleonora Aemitage. 



Mk. Miller Christy's interesting notes on the flowering of 

 Elms (pp. 36-41) led me to send him some of my owu data, and he 

 has asked me to send them to the Journal ; they are arranged in 

 tabular form for easy comparison. Taken with his, it Avill be seen 

 that there is a marked correspondence of flowering date for the same 

 years, allowing for the generally earlier incidence of the renewal of 

 vital activities in plants in the West Midlands (Herefordshire in this 

 case) over that of the Eastern counties. 



Thus it is seen that the climate of the flowering-months (January 

 to March) has a direct influence on the date, and short weather rsotes- 

 from my own observations are added to the Table.
