Excepting for the illustration given by Hedwig, little is known 
of this species in modern times. Mitten and Brotherus had not 
seen specimens. At the British Museum there is a specimen 
labelled ‘‘Leskea congesta Sw. Ind. Occ. ex Cl. Swartzio. J. Vahl,” 
which is evidently a mixture of Palamocladium leskeoides and 
Clastobryum trichophyllum. Hedwig’s description calls for a plant 
with entire somewhat secund, falcate leaves and a horizontal 
capsule, characters which do not agree with either of the species 
named above.
