 My Dear Friend 


 The books being called in for 
 annual examination at College Library, 
 I was greatly troubled at a missing 
 vol. [volume] of Botanical Magazine charged to
 me. I now recollect that it was 
 sent to you, to work up some Iridaceae
 from Herbert's long note. The librarian 
 is in a great stew about it. 
 Would you kindly return it on Monday 
 or Tuesday. 


 Your determinations of H. [Herbarium] Engelmann's
 Eriogoneae  sent by Thurber reached me 
 yesterday. Many thanks. 


 The localities you cite do not quite 
 correspond to my herbm. [herbarium] specimens. But 
 I can make out what you mean by each 
 I suppose. You have misplaced (or I) some 
 labels of localities.


 "E. [Eriogonum] effusum" I had so named. The flowers 
 are white, tinged reddish outside. But, the
 "E. [Eriogonum] effusum var? leptophyllum" has bright 
 golden yellow flowers, & cannot be same species, 
 [or? lost?]. I had thought it "E. [Eriogonum] brevicaule var.?
