Tour Wellborrr 



have not given ne for the longest time any news,, which would? 

 have put ne at ease about your well^eing; \ I was very mich anxious 

 about you, because in the volatile country, where you live, all 

 kinds of happenings can become disturbing t Büt in an indirfect way 

 I found out, that you still live in St. Louis, and that you have 

 been seen there and. have been spoken to.. But I do not know, if the 

 shipment of my work has gotten to you, and even less, what you thinkr 

 about it T I would have been very glad. to know your judgeraent, , and 

 that is still the case,. Withotdb inquiry, unf ortunately, , no work can 

 get created,, and thus I named a species of Cereus Pottsiiy which 

 you had however described as Greggil t This error has been already 

 corrected", and the species will retain the name Greggii. , Also,, con- 

 cerning the Leuchtenbergia , . Mr. Fischer fron Petersburg (Petrograd, 

 E.D.K wrote to me, that he considers the plants a^he type of a new 

 family, separated fron the cacti. - I" t seens, that the stränge fruit, 

 namely the bacca acuninata et stipitata, which Coli. Emory drew, and 

 of which ^four Wellborn ( in your letter of March 15» 1848) gave ne the 

 advise,does not belong to Greggil but to Leuchtenbergia. . Would it 

 be really thus ? The^Mr. Fischer would not be wrong.. On the one hand,, 

 I found out too late, on the other, the message is based solely on 

 the statenent of Mr. . Karwinski • . Wherever this Bacca, diverging frour 

 its form, may belong, if to Cer. Greggil ? (which I do not believe,« 

 and which does not develop fron your description) or to Leuchtenber- 

 gia- (which Is rather to be assuned) \ it remains still certain, that 

 such a bacca does exist, , and that the fact, that it is stipitata, is 

 of utmost importance (stipitatus= trunk or short stalk t E.D. ) • - 

 Your Wellborn could perhaps give an explanation about this, and 

 thereby offer a valuable Service to the history of cacti.
