Much smaller than the smallest form of T. TomenteUa (Erhr.) Nees, ever observed 

 by me and readily distinguished from it by its simple and rather distantly pinnate 

 stems. Its habitat, on rotten wood (to which it closely adheres), is also peculiar. 



T. Tomentosa (Swartz) Nees, has a similar ramification, but is also a much larger 

 plant, with the leaves strongly succubous (very oblique), and often not divided more 

 than half way to the base.
