  1)elong

  which 
  were 
  brought

  by 
  the 
  first 
  Regnellian 
  Ex- 
  

   pedition 
  which, 
  paid 
  for 
  from 
  the 
  funds 
  placed 
  by 
  Regnell 
  

   in 
  his 
  lifetime 
  at 
  the 
  disposal 
  of 
  the 
  Roy 
  al 
  Swedish 
  Acade- 
  

   my 
  of 
  Sciences, 
  during 
  the 
  years 
  1892 
  — 
  94 
  explored 
  the 
  Bra- 
  

   zilian 
  states 
  of 
  Rio 
  Grande 
  do 
  Sul 
  and 
  Måtto 
  Grosso 
  and 
  

   parts 
  of 
  Paraguay 
  and 
  El 
  Gran 
  Chaco, 
  beside 
  paying 
  a 
  short 
  

   visit 
  to 
  Bahia, 
  Rio 
  de

  and 
  S.

  When 
  I 
  began 
  to 
  name 
  the 
  Cyperacete 
  collected 
  by 
  my- 
  

   self 
  during 
  the 
  Urst 
  Regnellian 
  Expedition, 
  there 
  were 
  no 
  

   materials 
  for 
  comparison 
  here 
  in 
  Stockholm 
  and 
  I 
  was 
  there- 
  

   fore 
  obliged 
  to 
  work 
  through 
  a 
  part 
  of 
  the 
  older 
  collections. 
  

   It 
  was 
  soon 
  evident, 
  however, 
  that 
  such 
  a 
  task 
  would 
  be 
  a 
  

   waste 
  of 
  time 
  and 
  of 
  doubtful 
  value: 
  the 
  more 
  newly 
  de- 
  

   scribed 
  species 
  of 
  the 
  Cyperaceee 
  are 
  scattered 
  in 
  nume- 
  

   rous 
  books 
  and 
  papers, 
  and 
  very 
  few 
  even 
  of 
  the 
  difficult 
  

   genera 
  (e. 
  g. 
  Eleocharis) 
  are 
  to 
  be 
  found 
  illustrated, 
  and 
  for 
  

   comparison 
  there 
  were 
  only 
  unnamed 
  collections. 
  (Even 
  the 
  

   South 
  American 
  collections 
  of 
  Sagot, 
  Kappler, 
  Wright, 
  Lech- 
  

  

  ■ 
  ler, 
  and 
  others 
  have 
  to 
  a 
  great 
  extent 
  been 
  distribnted 
  

   without 
  names.) 
  

  

  At 
  my 
  request 
  the 
  Director 
  of 
  the 
  Botaniska 
  Riksmuseum, 
  

  

  [Professor 
  V. 
  B. 
  Wittrock, 
  therefore 
  had 
  the 
  whole 
  collection
