Closely as this species may appear at first sight to be allied to Trich. reptans (Ic. Fil. t. 32.) 

 and T. muscoides, yet a more careful examination will prove it to be abundantly distinct. It is 

 much smaller, has the fronds almost entirely sessile, more rounded and approaching to cordate, 

 deeply and constantly lobed at the margin. The texture of the frond, too, is very different ; here 

 it approaches nearer to that of many frondose Jungermannice, the reticulation is small, and the 

 nerves much less frequent, the main branches from the midrib or central nerve always following 

 the direction of one of the lobes. 



We are not aware that it has been found by any botanist but our friend C. S. Parker, Esq., in 



the island of Barbadoes.
