This is certainly no Thuidium, but a very close ally if not a variety of 

 Ambl. glaucum, and it may be noted that an approach to the dimorphous 

 leaves of the present plant may also be observed in the Var. sulcatum; the 

 papilla are usually very distinct on the bracts of the male inflorescence, but 

 are often but poorly developed on the leaves. The fruit has been found in 

 the Canton de Vaud, Switzerland, by PhiHbert.
