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. Hed wig'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.
