Wilmington, 



September 22, 1893. 



Bear Dr. Sandbar g, 



I return Holzinger 1 s list , the only specimens I have here to 

 compare are the following. The others I presume were returned to 

 you so that I cannot tell whether he or I is right in the cases 

 when we disagree. But of these now mentioned I am well satisfied. 

 539 he calls "Spiraea betulif olia, Pall but in inflor , approaching 

 S .Salisf ol ia, " That is just the reason Greene made it his S. 

 pyramidal is . 



158 "Potent illaNorvi^ ica w - my specimen is as I named it, P. 

 nivalis, Nutt . var. millegrana, Erigel . * 



745 "Aliiun att enn&f ol iurn, Kellogg" - my specimen is good A. 

 corn/aunv nodding flowers - my bulb from a rhizoma and all the rest. 

 355 "A. St el latum, Nutt i* - The specimens here correspond exactly 

 with specimens of A. serratum, Watson named by him. 

 I re-inclose his 1 ist . 



I have had much pleasure in going over the present sending 

 in which I already find some things of much interest although these 

 determinations are only tent at ive . Here is the list so far .
