  Involucral 
  scales 
  

   linear-sublanceolate,

  about 
  twice 
  the 
  length 
  of 
  the 
  disk, 
  squarrose 
  

   spreading, 
  scabrous, 
  ciiiate 
  at 
  the 
  base, 
  3-nervod 
  ; 
  chaff 
  shorter 
  than 
  the 
  ex- 
  

   panded 
  florets, 
  linear-oblong, 
  carinate, 
  acute, 
  commonly 
  a 
  short 
  tooth

   near 
  the 
  apex,

  Lobes 
  of 
  the 
  disk 
  florets 
  scabrously 
  ciiiate 
  

   at 
  the 
  base 
  ; 
  on 
  the 
  back 
  somewhat 
  lanose 
  and 
  appressed-hirsute, 
  chiefly 
  canes- 
  

   cent 
  at 
  the 
  junction 
  with 
  the 
  tube. 
  Receptacle 
  convex, 
  somewhat 
  distinctly 
  

   alveolate. 
  

  

  There 
  are 
  strong 
  grounds 
  for 
  considering 
  this 
  an 
  entirely 
  new 
  species, 
  rather 
  

   than 
  variety, 
  but 
  owing 
  to 
  the 
  lateness 
  of 
  the 
  season 
  we 
  prefer 
  more 
  ample 
  

   investigations 
  ; 
  for 
  the 
  present 
  it 
  may 
  rest 
  here. 
  The 
  parallels 
  of 
  other 
  species 
  

   will 
  be 
  given 
  hereafter. 
  

  

  Chionanthus 
  fraxinifolius, 
  Kellogg. 
  

  

  A 
  shrub 
  25 
  to 
  30 
  feet 
  high,

   oddly 
  pinnate,

  with 
  a 
  terminal 
  odd 
  one, 
  

   (5 
  to 
  6 
  inches 
  in 
  length.) 
  pinnules 
  petiolate, 
  about 
  I3 
  the 
  blade, 
  which 
  is 
  ovate 
  

   or 
  oval, 
  subacute, 
  serrate, 
  base 
  entire 
  and 
  abruptly 
  short-cuneate, 
  often 
  some- 
  

   what 
  oblique, 
  the 
  terminal 
  leaflet 
  obovate, 
  obtuse, 
  cuneate; 
  leaf 
  glabrous 
  

   throughout, 
  leaves 
  opposite. 
  Panicles 
  drooping, 
  peduncle 
  laterally 
  sub-com- 
  

   pressed, 
  numerously 
  subdivided 
  irregularly 
  in 
  alternate, 
  opposite, 
  verticillate, 
  

   and 
  fasiculate, 
  or 
  in 
  ultimate 
  pedicels 
  of 
  threes, 
  etc., 
  the 
  rather 
  minute 
  oblong 
  

   scarious 
  bracteoles 
  at

  the 
  slender 
  pedicels

  caducous 
  ; 
  

   glabrous 
  throughout

  4 
  to

  or 
  more, 
  obscurely-triangular

  or 
  

   mucronate 
  elevations, 
  or 
  notched 
  and 
  secondary 
  pseudo-teeth 
  ; 
  stamens 
  one 
  to 
  

   two, 
  filaments 
  short, 
  opposite, 
  alternating 
  the 
  petals, 
  scarcely 
  half 
  the 
  length 
  of 
  

   the 
  anthers, 
  or 
  longer 
  than 
  the 
  calyx 
  (1-line), 
  when 
  dry, 
  apparently 
  twisted, 
  co- 
  

   hering 
  with 
  the 
  petals 
  at 
  the 
  somewhat 
  expanded 
  base 
  into 
  a 
  partial 
  or 
  entire 
  

   short 
  ring 
  or 
  tube, 
  anthers 
  linear-oblong, 
  subcordate 
  base, 
  introrse, 
  cells 
  later- 
  

   ally 
  dehiscent, 
  fixed 
  by 
  the 
  base 
  ; 
  petals 
  oblong-oval, 
  obtuse, 
  claw 
  }^ 
  the

   or 
  if 
  coalescent 
  oblong 
  or 
  obovate, 
  (i£ 
  to 
  % 
  an 
  inch 
  in 
  length,) 
  distinct 
  or 
  

   slightly 
  cohering 
  into 
  a 
  partial 
  tube 
  (in 
  one 
  instance 
  only), 
  and 
  then 
  deciduous 
  

   with 
  the 
  stamens 
  ; 
  style 
  clavate, 
  notched 
  or 
  slightly 
  emarginate, 
  stigma 
  about 
  

   3^ 
  longer 
  than 
  the 
  filament, 
  shorter 
  than 
  the 
  anther 
  or 
  anthers 
  ; 
  drupe 
  fleshy, 
  

   oval 
  or 
  sub-globular 
  — 
  ripe 
  fruit 
  not 
  seen. 
  

  

  Collected 
  by 
  Dr. 
  William 
  0. 
  Ayres, 
  at 
  Borax 
  Lake, 
  about 
  four 
  years 
  ago. 
  

   The 
  description 
  is 
  made 
  from 
  very 
  imperfect 
  fragments 
  — 
  a 
  full 
  and 
  good 
  set 
  of 
  

   specimens 
  much 
  desired. 
  Although, 
  in 
  some 
  points, 
  this 
  shrub 
  fails 
  to 
  agree
