Ohrdruf in Thüringen, Jan. 28, I883 



Honored Sirl 



Just as I was about to answer your letter of the ?8th ult. I received notice from 

 the post office, that your package is laying at the customs bureau. in Gotha for me and 

 on the 25th I received it in good condition with all of the hlshly de" 1 ightful treasures 

 that it contained. First I did want to take a quick glance *nd yesterday and today 

 I used the few free hours I had to get a general ide=> of the contents. I would have 

 preferred to examine it all first before writing to you — but then it might happen 

 as before, and I am still provoked be cause of my silence at that time. Much, almost all 

 of it, is new to me: for instance the Ephedra -gall. Up to now one knows only 6ne note 

 (without description) about a Ephedra-gall from Sancpta, which was given by a Russian 



botanist. The and... conifer galls of the short-tips are much 



desired by me, because I have just examined similar ones of Erica . The dainty small 

 Short- tips and deformations of Euphorbia polycarpus are likewise caused by a gall-gnat 

 (Ceridomyia) , but in the outer form from which our European Euphorbias deviate which seems 

 to explain itself through the leaf position. 



Mitegalls I found up to now only a few in your raaterial: 1) Erineum Vitis (accord- 

 ing to the old designation) of such American Vitis - kinds, of which it is not yet known. 



2) The horn-shaped leaf-galls on Prunus - virginiacus (very similar to ours on Pr. Padus ). 



3) Wart-shaped leaf galls from Juglans californica (author? perhaps newly set up (estab- 

 lished) kind by you? My resources leave mein the lurch. Can you recommend a Flora for 

 the western U.S.? Gray's Manual of the Botany of the Northern U.S. 1863 is my all for 

 this Flora, irrespective of works without diagnosis like Steudel's Nomenclatur. Walsh 

 mentions on the Black Walnut (J. nigra ) two mite galls, but gives only scanty Informa- 

 tion about the one, nothing about the other. Our European Phy t opt o - C e c i dium of Julians 



are a different variety (Erineum and , -of both I am encl osing a sample), Are 



these forms entirely missing in the Northamerican Juglans varieties? *0 Of interest 



is the occurence of the terminal flowers of the spikelets of Bromus etc., which 

 through Phytophus deformation (and strong ............), in very similar or like manner 



of 3 German Bromus varieties, are known. Your label reads " Bromus , Banks of Twin Lakes, 

 Colorado, Aug. 28, 8l M . Is the identification of the species of this Bromus possible 

 for you? 



Like, or very similar to our European Cecidium forms are also the Populus -galls , 

 which in the previous year you received through pharmacies for this year, - as far as 

 I can judge the character without examination with knife and microscope -(the analogy is 

 missing with us) furthermore the Picea - pine-apple galls (P. E<rge Imannii among others)
