 ^' -DC. describes this plant as stemless, on theoretic grounds, considering that the 

 ^parent stem is formed by a complete adhesion of the petiole to the scape, and 

 J^Pporting this view by the statement that there are no stipules at the point whence 

 ^^ peduncles spring. If there were none at that point it would not establish the
