This plant lines the roof of a cavern called Sicsi-huaico (Sicsi, the Inca 
name of the Pampas-grass, Gynerium argenteum, and huaico, a cave or 
hollow) near the village of Banos, at the foot of Tunguragua, and occurs 
also on shady rocks in the same neighbourhood. I was unable to find 
flowers of either sex, yet I could not identify it with any species in perfect 
state growing near it, nor can I now safely attribute it to any described 
species. Old and decaying plants often get completely hidden under 
adventitious ramuli, growing from their leaves, and bearing minute bifid 
leaves that quite resemble those of a Cephalozia. While certainly allied 
to Pl. rutilans, it is possibly still nearer Pl. letevirens, to which the rami- 
fication and the rather closely-set leaves approximate it.
