_ Ihave stated my reasons for not adopting the genus Lepto- 
stomum under Gymnostomum Menziesii (Tan. VI.), a species 
near to which this ought certainly to rank, although it differs 
abundantly in the shape and direction of the capsule and the en- 
tire leaves. In this plant, too, the hair-like points of the leaves 
are much longer,
