The Mexican plant may be different from the Nicaraguan; but the one female spike 
belonging to Seemann’s specimen is quite like those collected by Bourgeau, and the 
male spikes collected by Tate differ only in their greater Jength. It may be one of the 
species of which we have seen no specimens, all of which were described from leaves 
alone.
