Dear friend, 
The plants which you sent me through Dr. W. O. Focke have arrived. With the 
renewed expression of my sincere thanks I shall make some remarks concerning these 
ptants below. 
Juncus acutus (robustus Wats.). I agree with you that the Californian 
J. acutus should not be separated from the European; however, with regard to the 
plants from the Cape, it is somewhat different, since these differ through a 
constant difference of the fruit and flowers. 
J. Drummondii, very beautiful specimen. 
J. rugulosus Engelm. This very spectacular plant is, as I discovered with 
certainty by a thorough study thereof, an ill plant through too much shadow and 
extensive humidity and I, therefore, ask you not to describe it. Branches and 
fruit are extremely faded, the 6 stamens are crippled entirely. It seems to me it 
belongs to J. nodosus or acuminatus, whereby the existence of the inner stamens 
(J. acuminatus has usually always 3 stamens!) did not change my opinion since 
this happens not seldom in abnormal cases. 
I hope that our new mail connection will further our botanical exchange; 
it is easy and cheap. Should you wish to have something from me, I am ready to 
send it to you. 
I recently saw in the hb. Boissier a pecular Juncus plant: Label Hall., Pl. 
Oregon No. 547 and 548 (or 567 and 568?) which seemed new to me. It was described 
as J. nodosus. Could you get this plant for me? 
I remain with greetings 
your devoted 
Fr. Buchenau
