  In 
  the 
  genus 
  Andropogon 
  are 
  included, 
  as 
  sections 
  or 
  subgenera, 
  

   some 
  grasses 
  which 
  have 
  been 
  known 
  as 
  genera, 
  and 
  here 
  some 
  con- 
  

   fusion 
  may 
  arise 
  for 
  the 
  student 
  — 
  on 
  page 
  61 
  the 
  subgenus 
  Chrysopogon 
  

   does 
  not, 
  as 
  might 
  be 
  supposed, 
  include 
  our 
  species 
  known 
  as 
  Chrysopo- 
  

   gon 
  nutans 
  and 
  C. 
  secundum, 
  these 
  being 
  by 
  Mr. 
  Hackel 
  placed 
  in 
  the 
  

   subgenus 
  Sorghum 
  although 
  they 
  are 
  not 
  specifically 
  mentioned. 
  The 
  

   Sorghum 
  secundum 
  Chap, 
  is 
  called 
  by 
  Mr. 
  Hackel 
  in 
  his 
  monograph 
  of 
  

   Andropogonese, 
  page 
  533, 
  Andropogon 
  unilaterale— 
  the 
  name 
  secundum 
  

   being 
  appropriated 
  by 
  the 
  A. 
  secundus 
  Willd., 
  now, 
  however, 
  made 
  a 
  

   synonym 
  of 
  A. 
  contcrrtus 
  Linn. 
  Again 
  on 
  page 
  63, 
  under 
  subgenus 
  

   Heteropogon, 
  there 
  are 
  " 
  5 
  species 
  in 
  the 
  tropics, 
  one 
  of 
  which 
  is 
  cosmo- 
  

   politan 
  as 
  far 
  north 
  as 
  South 
  Europe 
  and 
  North 
  America." 
  No 
  mention 
  

   is 
  here 
  made 
  of 
  the 
  Andropogon 
  melanocarpiis 
  Ell. 
  (Heteropogon 
  aciim- 
  

   inatus 
  Trin.) 
  which 
  is 
  found 
  as 
  far 
  north 
  as 
  North 
  Carolina. 
  This 
  omis- 
  

   sion 
  is 
  not, 
  however, 
  a 
  fault 
  of 
  the 
  translators, 
  but 
  might 
  have 
  been 
  cor- 
  

   rected 
  by 
  a 
  note. 
  On 
  page 
  74, 
  under 
  Eriochloa 
  it 
  is 
  said, 
  " 
  five 
  species, 
  

   in 
  the 
  tropical 
  and 
  subtropical 
  zones 
  of 
  both 
  hemispheres." 
  Two 
  or 
  

   three 
  at 
  least 
  of 
  the 
  species 
  extend 
  into 
  the 
  temperate 
  zone, 
  one 
  as 
  far 
  as 
  

   southern 
  Kansas. 
  On 
  page 
  110, 
  of 
  the 
  genus 
  Thurberia 
  it 
  is 
  said 
  " 
  species 
  

   two, 
  Arkansas 
  and 
  Texas." 
  The 
  range 
  should 
  be 
  extended 
  to 
  Florida, 
  

   and 
  I 
  think 
  there 
  is 
  but 
  one 
  species. 
  The 
  genus 
  Calamagrostis 
  is 
  here 
  

   made 
  to 
  include 
  Deyeuxia 
  as 
  a 
  section, 
  but 
  the 
  section 
  Cdamovilja 
  Gray, 
  

   is 
  raised 
  to 
  generic 
  rank. 
  Some 
  botanists 
  will 
  prefer 
  to 
  retain 
  it 
  as 
  placed 
  

   by 
  Dr. 
  Gray, 
  and 
  to 
  add 
  to 
  it 
  a 
  third 
  Floridan 
  species 
  C. 
  Curtisii 
  Vasey 
  

   fpublished 
  as 
  Ammophila 
  Curtisii 
  Vasey.) 
  

  

  These 
  instances 
  do 
  not 
  materially 
  detract 
  from 
  the 
  high 
  value 
  of 
  the 
  

   work, 
  but 
  are 
  referred 
  to 
  to 
  indicate 
  a 
  few 
  points 
  in 
  which 
  some 
  additional 
  

   editorial 
  notes 
  would 
  have 
  been 
  an 
  improvement. 
  

  

  The 
  remarks 
  made 
  in 
  the 
  volume, 
  respecting 
  the 
  habits 
  and 
  economic 
  

   and 
  medicinal 
  uses 
  of 
  certain 
  grasses, 
  are 
  of 
  great 
  interest 
  and 
  value. 
  

   Those 
  respecting 
  the 
  different 
  varieties 
  of 
  the 
  cultivated 
  Sorghum 
  {An- 
  

   ^'yogon 
  arundinaceus 
  Scop.) 
  are 
  especially 
  interesting, 
  although 
  many 
  

   W'll 
  prefer 
  to 
  keep 
  A. 
  hcdapemis 
  Sibth. 
  as 
  a 
  distinct 
  species. 
  The 
  notes 
  

   on 
  Saccharum, 
  on 
  sections 
  Eupanicum, 
  Setaria 
  and 
  Pennisetum 
  are 
  also 
  

   interesting. 
  The 
  adoption 
  of 
  the 
  genus 
  Zizaniopsis 
  for 
  Zizania 
  mdiacea 
  

   ^Iichx. 
  will 
  be 
  acceptable 
  to 
  botanists. 
  The 
  species 
  seems 
  to 
  be 
  rare 
  in 
  

   'he 
  northern 
  states, 
  although 
  it 
  is 
  recorded 
  in 
  Gray's 
  Manual 
  from 
  Ohio 
  

   and 
  doubtfully 
  from 
  Penn. 
  The 
  notes 
  relating 
  to 
  the 
  history 
  of 
  our 
  cul- 
  

   tivated 
  cereals 
  are 
  very 
  valuable.—
