(12)  Rudimentary  petals  almost  al- 
ways present  as  filiform  bodies  2-4 
mm.  long,  r'siug  from  the  surface 
of  the  ovary  opposite  the  sinuses 
of  the  cal}-x. 
(13)  Peduncles  and  calyx  villous- 
pubescent  or  in  age  nearly  canescent, 
the  spreading  purple  segments  densely 
erect — puberulent  with  thickish  purple 
hairs,  or  sometimes  greenish  and 
nearly  glabrous,  probably  through  ab- 
rasion ;  inflexed  tips  of  the  calyx-lobes 
in  the  bud  coherent  and  extending 
down  to  the  tip  of  the  column  ;  exte- 
rior of  the  calyx  hexagonal,  the  six 
faces  plane,  dull  whitish  to  greenish 
purple,  the  interior  of  the  tube  deep 
purple  more  than  half-way  down  to 
the  white  base,  which  surrounds  a 
hexagonal  purple  band  enclosing  the 
stamens. 
(14)  Surface  of  ovary  at  maturity 
somewhat  pyramidal,  rising  into  the 
short,  thick  terete  column,  which  is 
2-4  mm.  high  and  rather  deeply  six- 
lobed  at  the  summit  ;  stigmas  promi- 
nent, at  anthesispale-pink  and  densely 
spiculate. 
(r5)  Stamens  dull  pinkish-purple, 
anthers  dull  pink  ;  prolonged  tips  of 
the  filaments  slender-subulate,  from 
one  to  three  times  the  length  of  the 
anther  in  the  long  series  of  stamens.

(16)  Habitat :  From  Quebec  and 
Ontario  to  Western  Massachusetts, 
Southeastern  New  York  and  Penn- 
sylvania and  southward  in  the  Alle- 
ghanies  to  Virginia.  In  rich,  hilly 
woods,  often  in  rocky  situations.

(12)  Rudimentary  petals  usually 
wanting. 
(13)  Peduncle  and  calyx  densely 
cottony-villose,  much  less  so  in  age, 
the  outer  surface  of  the  sepals  loosely 
pilose-pubescent,  the  reflected  brown- 
ish purple  segments  somewhat  shining 
and  minutely  puberulent,  with  dull 
purple  hairs  and  faintly  parallel- 
veined  ;  inflexed  tips  of  the  sepals  in 
the  mature  bud  extending  only  half- 
way to  tip  of  column  ;  interior  of  the 
tube  white  or  greenish-white  below  the 
rim,  the  disk  surrounded  by  a  purple 
band,  as  in  Canadense;  exterior  of  flow- 
er white  to  greenish  purple,  the  hex- 
agonal base  with  prominent  rounded 
angles  and  intervening  depressions. 
( 14)  Surface  of  ovary  plane  or  nearly 
so;  column  slender,  columnar,  longer 
than  in  Canadense,  4-7  mm.  long, 
strongly  grooved  to  receive  the  longer 
series  of  stamens,  the  stigmas  greenish 
and  purple,  rather  smaller  than  in  Can- 
adense, and  often  merel}^  granulose. 
(15)  Stamens  deeper  purple  than  in 
Canadense,  with  shorter  anthers,  the 
filaments  slightly  longer  and  closer  to 
the  column,  their  tips  shorter  and  less 
attenuate,  often  less  than  half  the 
length  of  the  anther.    {Fig.  2.) 
(16)  Habitat  :  Southeastern  New 
York,  and  doubtless  Connecticut,  to 
Iowa,  south  to  the  mountains  of  North 
Carolina,  Missouri  and  Kansas.  Rich, 
low  woods  along  streams  or  river, 
valleys,  often  forming  extensive  beds  ; 
more  rarely  in  upland  woods  ;  flower- 
ing at  the  same  time  as  A.  Canadense.

Mr.  Bicknell  further  says,  regarding  A.  reflexnm,  that  "  it  would 
appear  that  a  geographical  variety  must  also  be  recognized.  Living 
specimens  were  sent  to  me  in  May,  1897,  collected  on  the  bank  of 
the  Desplaines  river  at  Maywood,  111.,  near  Chicago,  which,  though 
essentially  like  the  type,  show  characters  apparently  never  developed
