This species resembles S. amplum, W. West & G. S. West, but in the latter 
the sheath is differentiated into two parts, the pseudo-branches are narrower 
than the main filaments, and the trichomes are thinner than those of the 
former.

The genus Campylonema was established by Schmidle in 1900 (Hedwigia, 
xxxix. p. 181) to include his species C. indicum (syn. Stigonema indica, Schm.), 
which was collected at Bombay. This species was epiphytic on Hepaticæ, 
and it shows a combination of the characters of three genera (Stigonema, 
Tolypothrix, and Scytonema) as far as its branching is concerned. True 
branches are produced as in Stigonema, but there are likewise very rare false
