Ree. Jun. ? Königsberg in Prussia 
Jime 6. 1868 
Dear Friend ! 
Hea^ welcome to Europa« Unf ortunately I call tha payan much 
later than it should have been, as I was lately very strenously oc- 
cupied.iij examining flowering iteiTis..In order to get an overview of 
the quality of pollen, I counted the Unef pollen grains.good and bad,, 
of some 100 plants,in order to be able to better express the relationr 
in the perianth, . This is important to me because of the bastards^ of 
the Njrmphaeae, which have formed here«. Today I shall exanine a new 
bastard, which has just now developed its floT-^ers: Nuphar luteunr ^ X 
advena. This bastard is very interesting, varies in the color of the 
blossoms.and keeps the middle of both' older ones.. 
Nuphar advena - ipumilum and ■&umil um - advena unf o-'tunately do not yet 
f lower, . Of NuphaT* advena I srrew 9 year old seedlings in a pond, from 
seeds from Leipzig, which are shaped quite different from- the older 
plant in Leipzig. Nymphaea Stands the Winters here well; 
but floweres quite rarely; Nymphaea odorata is very tender, in the 
open can only be handled under cover; flowers little, never here, 
not even with artificial Illumination. You i/^n-ite, I am surrounded by 
Americans. The more so I wish, tha t you come here and comraunicate 
more detail. Is'nt that possible to accomplish You can stay with me; 
I have a guest-room^i But , you would have to come prior to the begiir- 
ning of July^ The middle of July I go to Lappland on account of the 
Nuphar-, which I cannot examine from the distance when dried; and , which 
I have not received alive despite all efforts' , and which I need.. 
The ministry has provided me with money for the trip..C'an't you come 
this month here ?^ I am of course quite sorry, that I cannot make the 
Problem easier for you^; A trip of 80 miles is not pleasant,but in^ 
13 hours you would be here. And you could see Nymphaeas at my place,, 
which you could not see in the entire worldi, In the open they are irr' 
part in their last flowering, and yesterday Nym. alba sphero
