In the rest, however, the definition is more exact, and is strictly main- tained ; for instance, in L. cernuum in a very large number of specimens a transition from the strobilus back to the vegetative shoot was never observed. The same is the case in the species associated as the group of L. clavatum, which are terrestrial trailing species, with well- defined strobili.
