naceae Ingl. the nestle family etc.are really simple grape type spore Systems 

 with other than spiral positioning and so many others that they cannot eaily be 

 fitted into the frame of this letter.- Another trend concerns Cell division and Cell 

 formation where one in the botanical field has gotten further than in the 

 zoological although the latter started earlier. The design and role of the nucleus 

 is similar in both fields; over the morphological variations has much new light 

 been shed- without the basic concepts being understood.An important result of 

 this are the interesting conclusions drawn also in Strassbourg over the role of 

 seed nucleus, a sort offruitionf?). Phanerogames. The main variations have 

 been mapped out in the Arara family in Engler's monography and Radtkopfer's 

 unending painstaking work- other neat variations are presumable known to you. 



The algae are in the forefront ofthe cryptogames; reliable data over the 

 systematic developmental history ofdoubtful groups such as Cattleya have been 

 obtained; beyond that it is mostly details once the main developmental track of 

 the larger groups has been determined. Even the restless preoccupation with 

 mushrooms focuses on details. I do not even want to talk about the "Antagonists" 

 they have been nearly beaten to death in the last decennium; Leitgab 's work on 

 the morphology ofliver mosses has served to fill in one large hiatus. 



I myselfhave finished after a long time large theoretical mushroom studies 

 some of which will be published. I assume you know that your son has been 

 selected the successor to Gestebach in Goettingen after we worked together for 

 15 years. He has received your recommendation with much pleasure and is very 

 grateful even if he in the daily hurly-burly forgets to write and say so. 



(Written upside-down. Trans.) The azolla sends greetings. If it will 

 survive this winter outside remains to be seen. Last summer it overgrew the 

 moats. In ?-land is it perennial and I have seen it overgrow European gardens. 

 The fruits are being preserved here.

Your question about Dr. Weber will 

 be ahswered on a postcard. I do not know iflcan get to see the old man 

 before Thursday and I do not want to delay the dispatch this time. Alivehe 

 is! I have ? regards for you from your nephews and add to thqffl my Wik* 

 and my wife's heartfelt ones.
