“ So very much does this species resemble D. pyriforme (Campylopus), Schultz, that it may readily be passed 
over as a state of that species, having the same soft appearance. The species referred to in the “Flora of New 
Zealand” as the typical form, gathered by Professor Jameson in the Andes of Quito, is a more robust species, with 
stiffer, less finely attenuated leaves, and a capsule rough at the base. Dicranum nodosum, Beauv. in Herb. Hook., 
is a much larger Moss, with leaves having a longer base, stouter nerve, and stiffer habit; it is in all probability 
synonymous with Campylopus nivalis, Brid. If Campylopus could be defined so as to distinguish it from Dicranum, 
there would be no necessity to alter the name of the present species, but it seems impossible to separate them in 
an extensive herbarium, notwithstanding the difference in the aspect of some of the species; and there being a 
Dicranum pallidum from North America previously published by Bruch and Schimper, an alteration has become 
unavoidable.” — Mit£en, l. c.
