In 1900 the late Mr. C. B. Clarke had the Cyperaceae collected by 
Ove Paulsen in Central-Asia and Persia for determination. When he 
sent the collection back with names, he wrote a letter to Mr. Paulsen, 
in which he proposed him to give the collection to me for closer deter- 
mination, as especially the Carices “are merely matched with plants in 
herb. Kew, and then the name on the Kew-plant is assigned to yours”. 
In 1902 I began to study the collection, but other works took my time, 
and it was not untill this year, that I could begin again on the deter- 
mination. In most cases I agree with the determinations made by Clarke, 
f. 1. in nearly all the species of Cyperus and Scirpus, but with regard 
to the Kobresia and Carex the differences are more frequent; especially 
he has not determined the distigmate Heterostachye correctely. When 
my determination differs from Clarke’s, I have always given his name 
in brackets or in notes. 
In some cases the name used by Clarke is a synonyme to that 
used by me, as he followed the Flora of British India by Hooker 
fil. and not always took the eldest name. 
The paper has been written entirely by me who consequently alone 
is responsible for it. I beg to express my thanks to the well-known 
Caricologist the Rev. G. Kiikenthal who has been good enough to give 
me the description of Carex pseudofoetida Kiik.
