there is a moss in the Kew Herbarium, from Griffith’s herbar 
labelled in Mitten’s handwriting P. nudiusculum, on ‘eal oes 
Sanah, 8000 ft. alt. in woods.” This was ehep se by Griffith in 
Bhotan (see Griffith, Journals of Travel, p. 245 (1847)). Griffith’s 
plant, however, differs from P, nudiuscudem - the wholly fuscous 
colour, taller stems, gets erecto-patent longer narrower leaves with 
linear lamina, and, moreover, is clearly either P. fuscatum Mitt. 
or a variety of that adee I have, however, received a specimen

J. Cardot, labelled “Sikkim; Darjeeling (leg. Moller, 1901).”
