  about 
  3-nerved,the 
  lateral 
  nerves

  sinus 
  (or

  : 
  peduncles 
  assurgent 
  or

  R., 
  6,000 
  feet 
  high 
  on 
  Sierra 
  Ne- 
  

   vada 
  mountains 
  ; 
  found 
  by 
  Kellogg 
  and 
  Brannan, 
  June, 
  1870. 
  

  

  This 
  plant 
  most 
  nearly 
  resembles 
  the 
  Span-long 
  Bind-weed, 
  Calystegia 
  spith- 
  

   amaa, 
  but 
  as 
  we 
  see 
  that 
  in 
  the 
  vicinity 
  of 
  San 
  Francisco, 
  it 
  has 
  not 
  the 
  leaf, 
  

   bracts, 
  calyx, 
  or 
  peduncles 
  ; 
  here 
  they 
  are 
  in 
  pairs, 
  and 
  the 
  whole 
  plant 
  more 
  

   naked. 
  This 
  also 
  includes, 
  probably, 
  C. 
  stans, 
  C. 
  acaulis 
  and 
  C. 
  tomentosa 
  ,- 
  

   it 
  cannot 
  be 
  C. 
  paradoxa, 
  for 
  that 
  has 
  linear 
  bracts, 
  etc. 
  

  

  Helianthus 
  giganteus, 
  var. 
  insidus, 
  Kellogg. 
  

  

  Found 
  on 
  a 
  recent 
  visit 
  to 
  an 
  island 
  of 
  the 
  San 
  Joaquin 
  River, 
  on

  paniculate; 
  branches

   smooth,

  to
