n. 1399, in valle Leito prope Ambato (8000 ped.), Spruce, n. 1400. 
Habitus omnino cum speciminibus Europzis conveniens. Folia parum 
tenuiora, cellulis basilaribus quadratis parum numerosioribus, czeteroquin 
vix diversum. 
Some very incomplete barren specimens of a species possibly 
distinct from H. albicans, under which name it was enumerated in 
the ‘ Crypt. Antarct.,’ were collected by Dr. Hooker in Hermite 
Island.
