 bücher, 1889). The vertical rhizome is very short, since

 which continue the growth of the rhizome, had as yet 

 only developed one pair of foliage leaves. The young roots 

 were comparatively thick at their base (1.5 — 2 mm), and the 

 cortical cells were full of starch. On the other hand, the
