My observations regarding the Juncus rhizoma were not changed much. In June 
I had to make a trip to the Rhine in order to visit new schools, in July the 
sudden death happened and together with the care for a dignified funeral ceremony, 
I had to take over the full burden. With great difficulty I was able to steal 
one day out of the summer vacations in order to make a very restoring trip to 
Wangenooge and Spickenooge. 
My critical review of the Alismaceae and Butomaceae is presently at the 
printers, so I am rid of this work at last for which I collected so much. To make 
the necessary corrections later is a great bother. 
Your Echinodorus seed unfortunately did not germinate; did you hear something 
about that from Berlin? The Agave, however, is coming up very well. 
J. conglomeratus and effusus are hard to define. I have studie= them care- 
fully for years. Differences in the dates of flowering, the capsules, the 
leaf sheaths are the same in thousands of specimens, even the much rarer 
J. conglomeratus it is locally (dry heather or something like this) growth 
among effusus and then after a long search one finds a middle form which lacks 
all the characteristics to declare it a bastard, the pollen of which are developed 
normally and the fertility remains unchanged. Real effusus shows not very seldom 
coiled inflorescences, on the other hand, congl. with flat inflorescences is 
much rarer. But also in the shape of the fruit and the building of the stem, 
there are certain differences, even though very seldom. 
Please exploit the Alps as much as you can with regard to Juncus and study 
the leaves carefully. How I would like to be with you there and we could make a 
race in drawing and making notes!' With friendly greetings to your wife, 
I remain
