The late Dr. Spruce and Mr. Pearson have concluded that there is 

 no specific difference between Jungermania sphcBrocarpa Hook., and J. 

 lurida Dum. = ?/. nana iSTees ; and, as the result of careful comparison 

 of a series of specimens of both plants, I feel bound to agree with them. 

 The cell-structure of the two is the same ; var. lurida is a smaller 

 plant, darker-colom-ed, and having a more compressed mode of growth.
