Remarks. Gemmae, more or less abundant, often in clusters,, 

 are present in most specimens. Fruiting plants collected by Mr. 

 Holzinger at Winona, Minn., have the leaves somewhat smaller 

 and the peristome less densely papillate. On some of the older 

 deoperculate capsules the teeth are whitish and nearly destitute of 

 papillae, as if these were deciduous as the result of prolonged ex- 

 posure. 



The gametophyte characters of Fabroleskea Austim indicate 

 that it belongs to the Leskeaceae, while the sporophytes point to 

 the Fabroniaceae, differing, however, from the latter by its papillate 

 peristome, which resembles very closely those of certain species of 

 Orthotrichum. Sullivant* remarks that " the generic position of this 

 species is still uncertain, related as it is by some of its characters 

 to Leskea, by others to Habrodon." Lesquereux and Jamesf 



make the same observation. 



The pseudannulus of Fabroleskea Austinixs analagous to the cells 



Fabro?iia pnsilla 



Habt 



odon. The loose exothecial cells are almost identical with those 

 of Habrodon perpusillns. It is, therefore, perhaps advisable, in 

 the present state of our knowledge, to refer it as an outlying genus 

 of the Fabroniaceae.
