Dear Doctor, 
I have received your friendly lines of January löth and have just half an 
hour until the post office closes to reply with a few lines and to let you know 
what happened to the Juncaceae which you sent in the autumn. I have received then, 
with much delay, but in good condition; however, without being able to find out 
who sent them to me here. Among them was the peculiar Juncus Kelloggi, then J. 
Parryi, the third form of J. triformis. These beautiful things made me curious, 
more than ever, to receive the end of your work in the Transactions which we 
unfortunately have not yet received. In this connection, it occurs to me that I 
have to renew my old request for a separate of your work in the Transactions. 
You know, without me telling you more about it, how important it is for me to have 
such a separate. 
I am very happy to hear you intend to fulfill your old promise to visit 
Europe again. How much changed you will find the fatherland which once you had 
to leave! You left a country torn apart, sunken into a dark slumber and shall find 
a mighty nation united in most important matters. Hopefully we shall meet personally 
and can exchange our opinions concerning the seed coat and the inflorescences. 
With regard to the latter I collected some material concerning the history of the 
development without, however, being able to reach a different opinion than that 
the flower, for instance in J. bufonius has a terminal with four front leaves. 
Could you perhaps before leaving North Americanarrange an exchange connection 
for me?. I should like to have more North American plants, for instance, 
Alismaceae, Juncaceae and Najadeae for myself, as well as all other families for 
the herbarium of our Museum to which I have given all my plants with the exception 
of the above-mentioned three families. I could send much in exchange. You, your- 
self will probably not be able to bring anything for me in the confusion of packing. 
Do you know the Alisma species tenellum Mart; from South and Middle America? 
And how do you differentiate them from your Echinodorus parvolus? I believe (even 
though I have only a very small specimen from your plant from the hb. reg. Berold.) 
that they are identical. The South American plant seems mostly to have less carpels 
in the flower; any specific difference I was unable to find between these two. 
Recently, I have asked Asa Gray to send me some male plants of Elodea 
canadensis (Anarcharis) in order to try whether by developing a fruit one is able 
to Stop the tremendous sprouting of this plant in Europe (where only female plants 
are existing). Should it be possible for you, please bring me a few ina gla?s
