   "This 
  is 
  one 
  of 
  my 
  most 
  valuable 
  introductions 
  into 
  South 
  Africa, 
  and 
  I 
  am 
  anxious 
  

   that 
  it 
  should 
  receive 
  attention 
  in 
  the 
  Southern 
  and 
  Southwestern 
  States 
  as 
  a 
  hay 
  

   crop. 
  

  

  " 
  Its 
  great 
  value 
  lies 
  in 
  the 
  rapidity 
  of 
  its 
  growth 
  and 
  maturity 
  (2 
  to 
  2\ 
  months), 
  and 
  

   I 
  have 
  heard 
  of 
  a 
  crop 
  having 
  been 
  grown 
  near 
  Bloemfontein 
  with 
  only 
  4 
  inches 
  of 
  

   rain. 
  

  

  "Being 
  sensitive 
  to 
  frost 
  it 
  is 
  only 
  suitable 
  for 
  regions 
  of 
  summer 
  rainfall, 
  which 
  

   may 
  partly 
  account 
  for 
  the 
  fact 
  that 
  it 
  never 
  ' 
  took-' 
  among 
  the 
  farmers 
  of 
  California, 
  

   where 
  I 
  introduced 
  it 
  many 
  years 
  ago."

   The 
  seeds 
  of 
  this 
  South 
  African 
  leguminous 
  shrub 
  were 
  received 
  under 
  the 
  

   name 
  Dichrostachys

  The 
  generic 
  name 
  Dichrostachys 
  was 
  published 
  in 
  

   1834 
  by 
  Wight 
  and 
  Arnott 
  (Prodromus

  In 
  

   1833, 
  however, 
  Guillemin, 
  Perrottet, 
  and 
  Richard 
  had 
  published 
  the 
  genus 
  

   Cailliea 
  with 
  one 
  species, 
  C. 
  dichrostachys, 
  based 
  on 
  Mimosa 
  nutans 
  Pers., 
  

   which 
  is 
  considered 
  to 
  be 
  congeneric 
  with 
  Mimosa 
  cinerea 
  L. 
  In 
  establishing 
  

   the 
  genus 
  Cailliea 
  the 
  authors 
  used 
  for 
  the 
  specific 
  name 
  of 
  their 
  plant, 
  dichro- 
  

   stachys, 
  which 
  had 
  been 
  used 
  by 
  De 
  Candolle 
  -(Prodromus, 
  vol. 
  2, 
  1825, 
  p. 
  445) 
  

   for 
  a 
  section 
  of 
  the 
  genus 
  Desmanthus 
  but 
  which 
  was 
  not 
  published 
  as 
  a 
  generic 
  

   name 
  until 
  1834. 
  The 
  earlier 
  generic 
  and 
  specific 
  names 
  are 
  both 
  here 
  restored. 
  

   Cailliea 
  nutans 
  is 
  found 
  on 
  the 
  west 
  coast 
  of 
  Africa 
  from 
  Sierra 
  Leone 
  south- 
  

   ward 
  to 
  Angola 
  and 
  on 
  the 
  east 
  coast 
  from 
  Abyssinia 
  southward 
  to 
  Mozambique. 
  

   " 
  Both 
  of 
  these 
  are 
  shrubs 
  or 
  small 
  trees 
  and 
  the 
  pods 
  are 
  eaten 
  by 
  game 
  and 
  stock, 
  

   much 
  as 
  is 
  the 
  case 
  with 
  the 
  mesquite 
  of 
  the 
  Southwest. 
  The 
  wood 
  of 
  Dichrostachys 
  

   nutans 
  {Cailliea 
  nutans) 
  is 
  very 
  hard 
  and 
  durable 
  and 
  is 
  much 
  valued 
  in 
  termite- 
  

   infested 
  regions 
  for 
  fence 
  posts, 
  in 
  spite 
  of 
  its 
  usually 
  crooked 
  habit 
  of 
  growth. 
  It 
  is 
  

   known 
  as 
  Sikhelbosch 
  or 
  Krul-peul. 
  

  

  " 
  Both 
  bushes 
  are 
  native 
  of 
  the 
  warm, 
  dry 
  middle 
  veld 
  below 
  4,000 
  feet 
  and 
  are 
  

   usually 
  found 
  in 
  sandy 
  or 
  gravelly 
  soils 
  in 
  regions 
  where 
  the 
  rainfall 
  is 
  from 
  20 
  to 
  25 
  

   inches, 
  falling 
  in 
  summer."
