  separate 
  

   at

  arising 
  from 
  the 
  claws 
  of 
  the 
  three 
  larger 
  divisions 
  ; 
  stigmas 
  

   six,

  the 
  Ar- 
  

   kansas 
  to

  banks 
  of 
  Red 
  river; 
  abundant. 
  Flowering 
  in 
  May 
  and 
  

   June. 
  

  

  This 
  genus, 
  notwithstanding 
  the 
  artificial 
  character, 
  is 
  more 
  nearly 
  

   related 
  to 
  Ixia 
  than 
  Moraea 
  ; 
  it 
  possesses 
  nothing 
  of 
  that 
  affinity 
  to 
  Iris, 
  

   either 
  in 
  the 
  inequality 
  of 
  the 
  divisions 
  of 
  the 
  corolla, 
  or 
  the 
  petaloid 
  

   nature 
  of 
  the 
  stigma, 
  with 
  which 
  the 
  stamina 
  also 
  alternate. 
  In 
  natu- 
  

   ral 
  aspect, 
  the 
  latter 
  species 
  of 
  this 
  genus 
  approaches 
  to 
  Tigridia, 
  but 
  

   differs 
  essentially 
  in 
  the 
  uncombined 
  stamens, 
  and 
  the 
  approaching 
  

   equality 
  and 
  conformity 
  of 
  the 
  petaloid 
  segments. 
  The 
  bulbs, 
  the 
  

   leaves, 
  the 
  stem, 
  the 
  general 
  form 
  of 
  the 
  flower, 
  and 
  that 
  of 
  the 
  capsule, 
  

   are 
  nearly 
  the 
  same. 
  The 
  nearest 
  affinity 
  of 
  this 
  genus 
  appears 
  to 
  be 
  

   to 
  Marica 
  paludosa, 
  from 
  which 
  it 
  differs 
  in 
  the 
  stigma 
  and 
  relative 
  

   magnitude 
  of 
  the 
  segments 
  of 
  the 
  corolla.

  Tillandsia

  The

   monly 
  called

  the

  of
