  The 
  description 
  is 
  quoted 
  soon 
  after 
  in 
  two 
  botanical 
  periodicals 
  (Ann. 
  

   Sci. 
  Nat.

  Bot. 
  12:

  1849;

  luxurians 
  Dureiu, 
  Bull. 
  Soc. 
  Acclim. 
  II, 
  9: 
  581. 
  1872. 
  The 
  author 
  

   in 
  speaking 
  before 
  the 
  society 
  mentions 
  a 
  grass 
  called 
  Teosinte 
  which 
  he 
  thinks 
  

   is 
  probably 
  the 
  name 
  of 
  a 
  country. 
  The 
  seed 
  probably 
  came 
  from 
  Guatemala. 
  

   He 
  speaks 
  well 
  of 
  it 
  as 
  a 
  forage 
  plant 
  and 
  ventures 
  to 
  call 
  it 
  Reana 
  luxurians. 
  

   The 
  name 
  is 
  not 
  technically 
  published 
  here 
  as 
  there 
  is 
  no 
  description.

  1876. 
  In 
  this 
  

   article 
  Fournier 
  reviews 
  the 
  synonymy 
  and 
  describes 
  the 
  genus 
  more 
  fully 
  

   than 
  his 
  predecessors. 
  He 
  describes 
  three 
  species, 
  E. 
  mexicana, 
  E. 
  hoiirgaei, 
  

   and 
  E. 
  giovanninii, 
  the 
  second 
  being 
  new. 
  He 
  distinguishes 
  the 
  last 
  species 
  

   on 
  description 
  only, 
  saying 
  that 
  he 
  has 
  seen 
  no 
  specimen 
  with 
  leaves 
  as 
  de- 
  

   scribed. 
  His 
  new 
  species 
  is 
  described 
  as 
  being 
  2 
  feet 
  tall, 
  annual, 
  and 
  the 
  

   staminate 
  inflorescence 
  as 
  consisting 
  of 
  a 
  single 
  terminal 
  spike. 
  The 
  locality 
  

   is 
  given 
  as 
  "In 
  collibus 
  prope 
  Chiquihuite 
  (Bourg. 
  absque 
  numerp), 
  octobri." 
  

   He 
  gives 
  the 
  locality 
  for 
  his 
  specimen 
  of 
  E. 
  mexicana 
  as 
  "In 
  arena 
  fluvii 
  

   €xsiccati 
  prope 
  mare 
  Pacificum, 
  vSan 
  Agostin, 
  octobri 
  (Liebm. 
  n. 
  548)."

  These 
  two 
  articles 
  appeared 
  about 
  the 
  same 
  time 
  and 
  covered 
  about 
  

   the 
  same 
  ground. 
  In 
  a 
  preceding 
  article 
  {Ueber

  1876) 
  Ascherson 
  discusses 
  

   the 
  relation 
  of 
  Euchlaena 
  to 
  Tripsaciim. 
  He 
  states 
  here 
  that 
  the 
  plants 
  of 
  

   E. 
  mexicana 
  were 
  cultivated 
  in 
  the 
  Berlin 
  garden 
  a 
  few 
  years 
  and 
  then 
  dis- 
  

   appeared. 
  In 
  the 
  herbarium 
  was 
  a 
  specimen 
  from 
  the 
  garden 
  and 
  one 
  de- 
  

   posited 
  by 
  Nees. 
  Ascherson 
  states 
  further 
  that 
  there 
  is 
  no 
  specimen 
  in 
  the 
  

   herbarium 
  at 
  Gottingen 
  to 
  interpret 
  Schrader's 
  description. 
  In 
  the 
  Trinius 
  

   Herbarium 
  at 
  the 
  Academy 
  of 
  Sciences, 
  Petrograd, 
  the 
  present 
  writer 
  saw 
  a 
  

   fragment 
  of 
  "Euchlaena 
  mexicana 
  Schrad. 
  e 
  Hort. 
  Goett." 
  

  

  In 
  the 
  first 
  two 
  articles 
  mentioned 
  Ascherson 
  discusses 
  at 
  some 
  length 
  

   the 
  history 
  of 
  the 
  genus 
  Etichlaena. 
  He 
  is 
  familiar 
  with 
  E. 
  mexicana 
  as 
  

   grown 
  at 
  the 
  Berlin 
  botanic 
  garden. 
  Previously 
  the 
  genus 
  had 
  been 
  placed
