 four places in the excavations for gravel near the London and Bath 

 Road ahove referred to ; Mr. W. R. Sherrin tells me he found this 

 uncommon var. in Savernake Forest some years ago, and I think his 

 locality is identical with mine. These excavations near Puthall Gate 

 are a capital locality for Polytriclin, the following kinds fruiting 

 and flourishing there : — nanum, aloides and var. Dicl^-aoni, urnic/erum, 

 pillferton, s.\\Aj ii nijjerinmn , and I noticed a tuft o^'forinoaum, which 

 liad probably' escaped from an adjoining wood. P. pUiferum Schreb.

 above referred to ; a very smalltuft near Folly Farm; this moss seems 

 rather scarce in this calcareous district. Mr. Knight informs me 

 he generally finds it growing with next species. -P. jnni'perinum 

 Willd. 7, S. Fairh" plentiful and fruiting in the excavation near the 

 London and Bath Road above referred to ; very sparingly near Folly

 common on trees in the South of England, often b}' water, and I have 

 found it very plentifully near Burnham-on-Sea in North Somerset (6*). 

 and have also seen it in Berkshire, near Hungerfoi-d (22*), and near
