THE LYCOPODS (CLUBMOSSES) 



a diagram; there are 34 pairs of chromosomes. Fig. 246^ (at a higher magnification) 

 shows the first meiotic metaphase for which a diagram is supphed in Fig. 244, again 

 showing n = 34. Confirmation of this number to the extent which is possible from sec- 

 tions has been made on roots of both Swiss and British material, in each of which 2n = 68 

 as nearly as can be determined.

L. annotinum, the next species, is rare in Britain as already pointed out. My material 

 of it is less complete than could be wished since the Scottish localities were inaccessible 

 during the war and in its only English station* it appears to be receding for chmatic 

 reasons. It was not fertile when I visited the Lake District in June 1939, and my
