Brotherus in describing this species says thai the nerve is <li'.iinet 

 from the lamina to the leaf apex; I find ii very ill defined above, 

 however. Also, he describes the capsule as erect, bu1 in the " Mu i ( 

 he places the species under the heading "Kaps. geneigt." This 

 appears to me the more accurate view, as the capsules are generally 

 ai leasi very slightly oblique. 



Negri (5a) has some periineni notes on this species. 'I he 01 iginal 

 planl described was a bright green {caespites viridissvmi) ; but, as 



Negri points OUt, the color may he yellowish. Both Colors 0CCUJ 111 



this collection. I [e also arrives a1 the same conclusion as the above 

 with regard to the inclination of the capsule.
