x ) In Fedde, Repert. XIX. (1923) 119 habe ich die Form erwähnt und bemerkt, daß sie wegen 

 des »caudex brevissimus . . . longissime fibrillosus« in die Nähe von P. Grayana gehören müßte. Der 

 Ausdruck fibrillosus bezieht sich aber hier nicht auf die erhalten bleibenden Blattnerven, sondern 

 auf die Adventivwurzeln.
