  COLLECTIONS 
  TOWARDS 
  

  

  the 
  dwarf 
  cane 
  commonly 
  noticed 
  by 
  the 
  colonists, 
  which 
  indeed 
  

   appears 
  to 
  be 
  nothing 
  more 
  than 
  a 
  variety 
  of 
  the 
  M. 
  gigantea. 
  

  

  Chloris 
  *verticillata. 
  Spicis 
  plurimis 
  verticillatis, 
  radiatis, 
  filiformi- 
  

   bus; 
  calicibus 
  acuminatis 
  bifloris; 
  flosculis 
  longe 
  aristatis; 
  gluma 
  exte- 
  

   riore 
  subbarbata; 
  caule 
  compresso.

  Hob. 
  On 
  the 
  sandy 
  banks 
  of 
  the 
  

   Arkansas, 
  near 
  Fort 
  Smith 
  ; 
  rare. 
  Flowering 
  in 
  June.

  Obs. 
  Peren- 
  

   nial. 
  Culm 
  compressed, 
  branched 
  from 
  the 
  base, 
  about 
  twelve 
  inches 
  

   high 
  ; 
  leaves 
  pale 
  green, 
  narrowish 
  and 
  flat; 
  sheaths 
  carinately 
  compressed 
  ; 
  

   stipules 
  obsolete, 
  hairy; 
  spikes 
  mostly 
  verticillated 
  in 
  two 
  series, 
  the 
  first 
  

   aggregation 
  consisting 
  of 
  from 
  seven 
  to 
  nine 
  spikes 
  ; 
  spikes 
  filiform 
  and 
  

   stellately 
  spreading, 
  pilose 
  at 
  the 
  base, 
  about 
  six 
  inches 
  long 
  ; 
  flowers 
  

   unilateral, 
  alternating 
  in. 
  two 
  rows; 
  calix 
  acuminate, 
  2-flowered, 
  one 
  of 
  

   the 
  flowers 
  perfect, 
  the 
  other 
  neuter, 
  the 
  dorsal 
  valves 
  of 
  both 
  gibbous, 
  

   obtuse 
  and 
  awned, 
  the 
  awn 
  more 
  than 
  twice 
  the 
  length 
  of 
  the 
  flower, 
  

   that 
  of 
  the 
  hermaphrodite 
  bearded 
  ; 
  seed 
  triangular, 
  smooth 
  and 
  even 
  ; 
  

   anthers 
  three 
  ; 
  stigmas 
  two, 
  brown. 
  There 
  are 
  few 
  grasses 
  in 
  America 
  

   more 
  curious 
  and 
  elegant. 
  Its 
  aspect 
  is 
  that 
  of 
  the 
  tropical 
  species.

  attenuata 
  (Eleusine 
  sparsa, 
  Muhl.

   135). 
  The 
  Chloris 
  mucronata 
  of 
  Michaux 
  appears 
  to 
  belong 
  to 
  this 
  

   genus, 
  and 
  is 
  evidently 
  distinct 
  from 
  the 
  plant 
  of 
  Pursh 
  and 
  Muhlen- 
  

   berg, 
  which 
  has 
  digitate 
  spikes, 
  is 
  more 
  nearly 
  related 
  to 
  Chloris, 
  and 
  

   forms 
  the 
  genus 
  Dactyloctenium 
  of 
  Wildenow 
  and 
  Sprengel. 
  

  

  Eleusine 
  Indica. 
  — 
  Hab. 
  The 
  banks 
  of 
  the 
  western 
  rivers 
  in 
  the 
  

   United 
  States 
  appear 
  to 
  be 
  the 
  only 
  genuine 
  locality 
  of 
  this 
  intrusive 
  

   grass, 
  which, 
  from 
  the 
  coast 
  of 
  the 
  Atlantic 
  to 
  the 
  garrison 
  of 
  the 
  

   Arkansas, 
  uniformly 
  infests 
  gardens, 
  court 
  yards, 
  and 
  in 
  the 
  towns 
  

   even 
  the 
  pavements 
  of 
  the 
  streets. 
  Bearing 
  to 
  be 
  trampled 
  upon 
  without 
  

   injury, 
  it 
  thus 
  occupies 
  places 
  where 
  scarcely 
  any 
  other 
  vegetable 
  can 
  

   subsist. 
  As 
  it 
  is 
  equally 
  common 
  to 
  India, 
  the 
  West 
  India 
  islands 
  and 
  

   North 
  America, 
  it 
  probably 
  extends 
  through 
  both 
  hemispheres.

  (Chloris

   Throughout

  country 
  in 
  elevated 
  prairies.

  The 
  

   spikes 
  ill 
  these 
  more 
  perfect 
  specimens 
  than 
  those 
  which 
  I 
  collected 
  in 
  

   the 
  Missouri 
  territory, 
  are 
  commonly 
  three 
  in 
  number, 
  and, 
  after 
  the 
  

   manner 
  of 
  the 
  genus, 
  alternately 
  disposed 
  along 
  the 
  rachis 
  for 
  a 
  distance 
  

   of 
  about 
  three 
  inches, 
  including 
  the 
  terminating 
  one.
