Could this be the source-form ? Is this variety found in Mexico ? 

 And is the plant there also almost without spin.es ? A very spiny form 

 of it, is, I believe, 0. anyclaea . Generally, I daily lose ever raore 

 the res^ect for spines as species characteristics, and in a whole 

 set of forns, -whieh are called Dillen! i t tuna » honick , pseud otuna , glau - 

 cophylla etc, seen to me - acoording to the fruit s - to belong toge- 

 ther. Flowers and: fruits nust be studied,and I hope you have lots of 

 material and observations brought alorg ^ron over in Mexico, 



The dif f iculties in our Wardens are multiplied so rauch by circum - 

 stances, because the plant s have almost never an?/ fruit, and, possibly» . 

 even worse , that they are bei ng propagated throu.gh outtirgs, thus only 

 a Single f orm, presenting a Single individual, not a species ! But, you 

 know all this yourself just as well, 



Your letter is so rieh on observations and reraarks, that it will be 

 of highest interest to ne, to read through it again in your presence. 

 A lot will come fron it. So raany of your reraarks agree with ny obser- 

 vations and ideas; others lead to questions and di ssertation. 



And now f are- well, and let ne hear soon fron you, Your 



Dr. Georg Engelnann
