Lycopodium lagopus

Lycopodium lagopus (One-cone Clubmoss) is similar to Lycopodium clavatum (Stag’s-horn Clubmoss) but as the name suggests has a higher frequency of one-coned fertile shoots. It was first reported in the British Isles in 2007.

Readers with a long memories may recall seeing this in July 2009:


Curly Lycopodium

Whilst there are not many single-coned shoots in evidence, this population shows other L. lagopus characteristics – the cones do not have stalks, there are  annual growth constrictions and the vegetative branching is fairly erect.  Misshapen cones are also known from a L. lagopus population at Drumochter. However, it does not look like “typical” L. lagopus as understood from the few known British populations. The hybrid may be worth consideration. In any event a return to the site this year is called for in order to assess it properly.
