which hopefully will soon be in print,and which X xvill send you 

 immediatelyy , T take the liberty, to direct your attention to a spe- 

 cies described and illustratedr as- C. umbonata » I do not know, where 

 this kind of a form belongs in the Classification adopted by yom 

 ürif ortunately, I cannot share it with you, as I have only seen it irr 

 the Herbarium of Sonder; r always hope, to convince Dr.F.Mlfllerr to
