This fine sjiecies is well distinguished by its very long glumes, rivalling in that respect 

 Chnsqiien aristata, Munro, which it resembles in many respects, although of course 

 widely separated from it by the character of its foliage.

A very fine grass, unlike any other of the genus, with most remarkably long-petioled 

 leaves, and very curious a2ipendages or auricles to the vagina. 



Fendler, no. 2501 !, from Colonia Tovar, in Venezuela, is probably another species of 

 Planotia. I have, however, only seen some leaves of this, which are 6 feet long and 5 

 inches broad, with unusually long ligules. Pendler states that it had never been seen m 

 flower or fruit.
