Hegelmaier Hov. 18,1864 * 2 * 



corresponds with this, specially in the Stigmata reflexa per - 

 sistentia, which I do not know from any other form. Further, I can 

 not accept until now the one communicated to Braun from Arkansas 

 with short stems, which you call now Engelhardiana Aust. as a 

 species of Nuttall 11 ( -^SBry-^S^ ) ; I carefully softened fruits 

 of all forms,, let them then somewhat harden in alcoholland therc 

 sketched them f finally sectioned them in as thin slices as possible 

 betweerc hollumtrank (I do not know this word.E.D. ) »and sketched 

 them too. . According to this procedure and the Sketches, which I 

 still keep,I can not find any difference in form in the fruits; 

 some differences in form are due to dep^rees of maturity,and un- 

 even spreading associated with it f and resolve themselves, if one 

 brings the sections obtained above under the microscope. I have 

 l^very short stemmed forms, which I can not at all separate from ; 

 Nuttallii f dUi üef lexa ) from Pennsylvania in the Viennese herbarium; 

 one collected by Moser with specific locatiorr data. May the£e spe- 

 cimens not come from there» and the labels.have been mixed up V 

 In part these forms carry the designation C. terrestris Raf in. ; 

 Under this designation I found types in various herbaria as 

 verna verlandf ormey , and, thus, could not make use of the name 

 C* terrestri s Raf. • 



I also noticed there, that certain forms of C.Asa Gr ayl , 

 de pending on the leaves, are designated C( linearis Proh. and 

 idf. heterophylla ; however, Pursch specifically dif f erentiated these 

 forms by their most important point, the fruits. And which of the 

 names by Pursch was to be given to the entire snecies ? I also 

 found north-americam. specimens designated as £f linearis , though 

 I could not see if they belonged to C^Asa Greyl as they were ste-

rather many specimens came before my eyes.
