Differs  from  glabrous  or  subglabrous  forms  of  the  similarly 
amphicarpous  Bidens  Anthriscoides  DC.  in  the  dissection  and  outline 
of  the  leaflets,  in  its  proportionately  much  longer  external  involucral 
bracts,1  and  in  its  straighter  achenes.  The  general  aspect  is  some- 
what like  that  in  stunted,  slender  forms  of  B.  pilosa  var.  bimucronata 
f.  odorata  (Cav.)  Sherff,  but  the  very  narrow  external  bracts  and  the 
dimensions  of  the  flowering  and  fruiting  heads  (the  latter  with 
fewer  achenes)  distinguish  it  from  that  form.

Type  specimen:  Collected  by  Edouard  Francois  Andre,  No.  2878, 
at  altitude  of  1,250  meters,  Rio  Juanambu,  Colombia,  April  28, 
1876  (Gray). 

Distribution:  Known  only  from  type  locality,  Rio  Juanambu, 
Colombia. 

Specimens  examined:  Andre  2878  (type,  Gray:  cotype,  Kew). 

The  type  specimen  was  restudied  in  1922  and  again  in  1925. 
The  20-30  areolae  on  the  old  disks  become  prominent  as  the  invo- 
lucres reflex.  There  are  37  heads  on  the  type.  The  plant  appears  to 
be  entirely  herbaceous,  but  the  label  says  "suffrutesc.,"  hence  the 
lower  part  of  the  plant  (not  present  on  the  sheet)  may  have  been 
woody.  The  species  stands  very  close  to  B.  pilosa  var.  alausensis  f . 
scandicina  (H.B.K.)  Sherff,  from  which  it  appears  to  differ  in  its 
taller  stature,  more  acutely  tetragonal  stems,  longer  internodes, 
finally  much  reflexed  involucres,  and,  most  of  all,  its  very  minute 
flowering  heads,  these  measuring  only  about  4  mm.  high  and  equally 
wide.1

1  It  may  be  observed  that  in  the  somewhat  comparable  case  of  B.  ramosissima 
Sherff  the  finally  reflexed  involucres  and  the  minute  size  of  the  flowering  heads 
were  later  concluded  to  be  only  subformal  variations  of  B.  pilosa  var.  bimucronata 
f.  odorata  (Cav.)  Sherff.

Type  specimen:  Collected  by  Jean  Luis  Berlandier,  No.  1010, 
Cordillera  de  Guchilaque  (near  Cuernavaca,  State  of  Morelos), 
Mexico,  October,  1827  (Del.).1 

Distribution:  Southwestern  Mexico. 

Specimens  examined:  Berlandier  1010  (type,  Del.,  3  sheets: 
cotypes,  Brit.;  Flor.;  Par.);  idem  1152,  Cordillera  de  Guchilaque,

vel  obsoletis;  Par.);  C.  G.  Pringle  11822  pro  parte,  ravine  near 
Guadalajara,  Jalisco,  October  17,  1903  (Field). 

As  stated  before  (Sherff,  loc.  cit.),  examination  of  cotype  material 
in  London  (Brit.)  and  Paris  (Par.)  shows  the  species  to  have  radiate 
heads,  not  discoid  as  described  by  DeCandolle,  exterior  involucral 
bracts  much  shorter  than  the  interior,  not  subequal,  and  some  of  the 

1  No.  1010  is  the  first  cited  specimen  and  hence  may  pass  as  the  type.  De 
Candolle  founded  the  species  upon  Berlandier 's  Nos.  1010  and  1152,  both  from 
the  same  locality.  The  specimens  are  identical.

pro  parte,  ravine  (barranca)  near  Guadalajara,  State  of  Jalisco, 
Mexico,  October  17,  1903  (Kew). 

Distribution:  Known  only  from  type  locality,  near  Guadalajara, 
State  of  Jalisco,  Mexico. 

Specimens  examined :  Pringle  11822  pro  parte  (type,  Kew:  cotypes, 
Berl.;  Gray;  U.S.). 

Pringle  11822  in  the  Herbarium  of  Field  Museum  has  the  leaves 
tripartite  and  matches  the  type  material  of  B.  Anthriscoides  DC. 
(Berlandier  1010,  Del.;  Brit.;  Par.)  fairly  well  except  in  being  gla- 
brate.  Elsewhere,  the  specimens  of  Pringle  11822  are  seen  to  have 
delicately  bipinnate  leaves,  similar  to  those  of  B.  pilosa  var.  bimu- 
cronata  f.  odorata  (Cav.)  Sherff.  Through  this  form,  apparently  best 
regarded  as  a  variety,  B.  Anthriscoides  DC.  is  found  to  be  rather 
closely  related  to  a  form  (the  B.  inermis  Wats.)  of  B.  pilosa  var. 
bimucronata  f.  odorata  (Cav.)  Sherff.1

OF  'THE 


THE  GENUS  BIDENS  355 

This  species  was  stated  definitely  by  DeCandolle  (loc.  cit.)  to 
come  from  Mexico,  but  Kunth  (H.B.K.  loc.  cit.)  was  uncertain  as  to 
its  native  country.  It  is  known  definitely  only  from  Guatemala. 
DeCandolle  commented  upon  the  closer  affinity  of  the  achenes  with 
those  of  Bidens  than  with  those  of  Cosmos.  Whether  he  altered  the 
specific  name  through  intent  or  through  error,  I  am  unable  to  say.1 
But  later,  Schultz  Bipontinus  (Seemann,  loc.  cit.),  who  frankly 
declared  his  belief  that  Cosmos  was  not  a  valid  genus,  used  this 
altered  name  in  citing  it  as  a  basis  for  his  Bidens  Kunthii,  which 
latter  name,  according  to  the  International  Rules,  cannot  stand. 

Asa  Gray  (Proc.  Amer.  Acad.  19:  16.  1884)  strongly  suspected 
that  this  plant  was  merely  Bidens  humilis  H.B.K.  and  suggested  a 
reexamination  of  the  type  material.  Kunth  (H.B.K.  loc.  cit.)  had 
described  the  color  of  the  ligules  as  "violacea,  basim  versus  sulphurea." 
This  description  is  borne  out,  not  only  by  the  coloring  in  the  plate 
cited  (that  is,  in  copies  of  Kunth's  work  having  the  plates  colored, 
as  in  John  Crerar  Library,  Chicago),  but  by  the  type  specimen  in 
Paris,  clearly  the  one  from  which  the  plate  was  made.  This  speci- 
men, though  faded  as  to  its  rays,  shows  at  least  that  the  proximal 
ends  of  the  rays  were  colored  differently  from  the  remaining  portions, 
which  latter  seem  surely  to  have  been  some  shade  of  red. 

More  recently,  there  has  been  collected  in  the  Department  of 
Amatitlan,  Guatemala,  fine  material,  Heyde  &  Lux  6173,  which 
belongs  here.  Singularly  enough,  it  had  been  determined  by  John 
Donnell  Smith  as  Bidens  humilis  (cf.  Gray,  loc.  cit.),  but  the  roseate 
rays  and  more  or  less  Cosmos-like  aspect  are  very  distinct.  The  color 
of  the  rays  in  the  dry  condition  varies  from  a  pronounced  roseate 
to  a  faded  yellowish  color,  rather  than  showing  a  distinct  sulphureous 
color  definitely  located  toward  the  base  as  described  by  Kunth. 
Still  further  material  from  the  same  small  district  in  Guatemala, 
W.  A.  Kellerman  6112,  has  been  collected  and  fortunately  is  in  a 
more  mature  condition.  The  ripe  achenes  match  the  ovary  figured 
by  Kunth  and  show  that  there  is  not  the  slightest  tendency  to 
become  rostrate  as  in  most  species  of  Cosmos. 

An  examination  of  the  original  description  of  Bidens  parvulifolia 
(Sherff,  loc.  cit.)  shows  that  the  second  cited  specimen,  Heyde  & 

1  In  his  Prodromus  Herbarium  DeCandolle  had  mistaken  a  single  large  speci- 
men of  Bidens  pilosa  var.  bimucronata  f.  odorata  (Cav.)  Sherff  for  this  species.  The 
original  label  had  said  "Bidens  Cavanilles"  and  from  the  peculiar  fades  of  the 
plant,  the  writing,  etc.,  it  is  clearly  one  of  the  original  specimens  of  Bidens  odorata 
Cav.  that  had  been  sent  out  by  Cavanilles.  On  the  cover,  DeCandolle  originally 
had  written  "B.  Chrysanthemoides?  H.B.K."  but  later  had  changed  the  "B."  to 
"C." 


356  FIELD  MUSEUM  OF  NATURAL  HISTORY— BOTANY,  VOL.  XVI 

Lux  6162,  seen  in  the  United  States  National  Herbarium,  was 
obtained  by  the  same  collectors  at  the  same  altitude,  locality,  and 
time  as  Heyde  &  Lux  6173.  The  dried  ligules  were  yellowish, 
the  leaves  were  pubescent,  and  all  but  the  top  pair  were  simple. 
Since  then  I  have  found  other  specimens  (Heyde  &  Lux  6162)  show- 
ing numerous  intergradations  between  the  simple,  pubescent  leaves 
and  the  compound,  mainly  glabrous  leaves;  also,  variations  to  a 
roseate  color  are  shown  in  the  rays.  Thus  Bidens  parvulifolia, 
incredible  as  it  may  seem  to  any  botanist  who  does  not  have  at  hand 
the  intermediate  specimens,  must  be  interpreted  as  merely  a  form 
of  Bidens  Chrysanthemifolia  having  minute,  mainly  undivided  leaves. 
B.  Chrysanthemifolia  offers  a  perplexing  approach  to  B.  pilosa 
var.  bimucronata  f.  odorata  (Cav.)  Sherff.  It  seems  significant, 
however,  that  among  the  large  number  of  specimens  of  the  rather 
widely  distributed  f.  odorata  examined  from  elsewhere  than  in  the 
Department  of  Amatitlan,  Guatemala,  none  have  been  found  to 
present  the  gradations  from  glabrous,  decompound  to  pubescent, 
undivided  leaves  that  B.  Chrysanthemifolia  presents.

Type  specimen:  Collected  by  Abadia  around  Lima,  Peru,  in  1833

Specimens  examined:  Abadia,  Lima,  Peru,  1833  (type,  Del.); 
Bro.  Ariste-Joseph  A832,  Choaclu,  above  Bogota,  Colombia,  July 
(U.S. ;  forma  internodiis  longissimis) ;  Alexander  Mathews  738,  Lima

Bidens  Abadiae  DC.  was  founded  upon  a  specimen  collected  at 
Lima,  Peru,  in  1833.  The  leaves  of  the  type  are  bipinnatisect,  and 
the  general  aspect  of  the  foliage  is  comparable  with  that  of  B.  pilosa 
var.  bimucronata  f.  odorata  (Cav.)  Sherff.  In  the  Boissier  Herbarium 
is  the  plant  from  the  Pa  von  Herbarium,  and  collected  at  Lima  or  in  its 
vicinity,  a  plant  matching  the  type  very  closely  in  its  bipinnatisect 
foliage.  The  technical  characters  of  both  the  old  and  young  heads 
on  these  plants  are  very  similar  to  those  often  met  with  in  B.  pilosa 
L.  The  general  habit  is  so  distinct,  however,  that  to  equate  B. 
Abadiae  and  B.  pilosa  would  seem  unjustifiable.

Type  specimen:  Collected  by  Hugh  Cuming,  No.  1041,  Lima, 
Peru,  in  1831  (Kew,  2  sheets). 

Distribution:  Peru. 

Specimens  examined:  Cuming  1041  (type,  Kew,  2  sheets); 
W.  Nation,  cultivated  places,  Lima,  1862  (Kew);  ex  herb.  Pavonii 
ex  Peru  (Webb) ;  Dr.  &  Mrs.  J.  N.  Rose  18740  p.  p.,  Santa  Clara, 
July  18,  1914  (N.Y.). 

In  the  Webb  Herbarium  at  Florence  is  the  additional  specimen 
(just  cited)  from  the  Pavon  Herbarium,  and  collected  in  Peru.  This 
has  the  leaves  merely  tripartite,  with  the  terminal  lobe  subtripartite. 
The  specimens  by  Cuming  and  by  Nation,  all  from  Lima,  likewise 
differ  from  the  DeCandolle  type  of  B.  Abadiae  in  having  leaves 
only  once-divided.  One  of  the  Cuming  specimens  has  leaves  ap- 
proaching those  of  the  related  B.  pilosa  var.  alausensis  (H.B.K.) 
Sherff.  Since  the  difference  between  the  simply  pinnate  and  the  bi- 
pinnatisect  types  of  foliage  appears  here  to  be  emphatic,  as  in  the 
varieties  of  B.  pilosa,  I  have  given  the  name  pilosoides  to  the  variety 
having  3-5-partite  leaves.

Type  specimen :  Collected  by  Townsend  S.  Brandegee,  in  vicinity 
of  San  Luis  Tultitlanapa,  State  of  Puebla,  near  the  Oaxaca  boundary 
line,  Mexico,  1908  (Calif.,  2  sheets). 

Distribution:  Known  only  from  type  locality,  vicinity  of  San 
Luis  Tultitlanapa,  State  of  Puebla  (near  Oaxaca  boundary  line), 
Mexico. 

Specimens  examined :  Brandegee,  vicinity  of  San  Luis  Tul- 
titlanapa, 1908  (Calif.,  first  type  sheet);  idem,  eodem  loco,  July,  1908 
(Calif.,  second  type  sheet);  C.  A.  Purpus  4429,  eodem  loco,  August, 
1908  (Calif.). 

The  first  type  sheet  bears  two  fine  specimens,  the  larger  one 
having  its  leaves  bipinnately  divided.  The  specimens  on  the  second 
type  sheet  have  the  leaves  mainly  3-5-partite,  as  in  B.  pilosa.  The 
achenes  suggest  those  of  B.  pilosa  var.  bimucronata.  The  ray  florets 
suggest  the  ray  florets  of  B.  pilosa  var.  radiata.  The  combination 
of  achenial  and  radial  characters  with  the  strange  general  aspect 
(especially  in  the  case  of  the  first  specimen,  with  its  bipinnate  and 
particularly  white-hispid  foliage)  is  one  that  I  have  never  observed 
in  authentic  material  of  B.  pilosa.  It  seems  best,  therefore,  to  retain 
B.  Brandegeei  as  a  separate  species.

Type  specimen:  No  type  was  cited.  The  habitat  was  given  as 
Virginia  and  the  first  pre-Linnean  reference  given  for  a  synonym 
(Chrysanthemum  aquaticum,  foliis  multifidis  cicutae  nonnihil 
similibus,  virginianum.  Herm.  lugdb.  416.  1690)  relates  definitely 
to  a  Virginia  plant.1  The  nativity  of  the  specimen  in  the  Linnean 
Herbarium  is  not  indicated  on  the  sheet. 

Distribution:  Rhode  Island  to  Florida  and  westward  to  Kansas 
and  Mexico;  rare  in  California;  scattered  in  French  Guiana,  Brazil, 
Argentina,  Chile,  etc.;  common  in  northern  Italy  and  the  Tyrol 
and  extending  into  France;  also  in  British  East  India,  China,  Corea, 
Japan,  Kordofan,  islands  of  Madagascar  and  Sokotra  (east  coast 
of  Africa),  Lizard  Island  (northeast  coast  of  Australia),  Philippine 
Islands,  etc.  Probably  native  in  recent  times  only  to  the  eastern 
United  States  and  eastern  Asia,  elsewhere  introduced.2 

Specimens  examined:  Ambrosius,  in  vineyards,  Valsugana,  Italy 
(Del.);  anon.  (Linn.,  sub  num.  6  et  nom.  bipinnata);  anon.  63, 
Lizard  Isl.,  northeast  coast  of  Australia,  April,  1861  (Mus.  V.,  2 

1  In  early  days  the  boundaries  of  Virginia  extended  much  farther  west,  of 
course,  than  at  present.    It  may  be  added  that  in  the  later  (posthumous)  work  of 
Hermann's,  his  Paradisus  Batavus  (pi.  123.  1698),  a  crude  illustration  of  an  entire 
plant  was  given,  accompanied  by  the  slightly  modified  name  Chrysanthemum 
Virginianum  foliis  Cicutae  nonnihil  Similibus.     The  plate  was  positively  of  our 
Linnean  B.  bipinnata. 

2  Other  authors  have  commonly  regarded  this  species  as  native  to  the  United 
States,  whence  introduced  elsewhere.     The  characteristic  and  quite  individual 
aspect  found  in  much  of  the  Asiatic  material,  an  aspect  that  has  persisted  through 
specimens  collected  many  years  apart  (and  has  occasioned  the  employment  of 
separate  specific  names),  leaves  no  doubt,  however,  that  eastern  Asia  has  been  a 
home  to  this  species  since  prehistoric  times.

1913  (N.Y.). 

Tausch  (loc.  cit.)  had  sought  to  distinguish  among  five  forms 
cultivated  in  gardens  under  the  name  B.  bipinnata.  He  described 
each  form  separately,  retaining  one  as  B.  bipinnata  and  creating 
new  names  for  the  other  four.  B.  Cicutaefolia  Tausch  and  B.  Myrrhidi- 
folia  Tausch  each  is  represented  by  one  of  his  own  cultivated 
specimens  (Lps.)  and  is  seen  to  be  purely  B.  bipinnata  (vide  sub  B. 
biternata).  The  meager  description  of  B.  tenuifolia  Tausch  matches 
B.  bipinnata  as  far  as  it  goes.  A  plate  cited  by  Tausch,  "Chrysanthe- 
mum cannabinum  etc.  Moris.  Hist.  3™:  tab.  7,  fig.  23,"  is  of  B. 
bipinnata  and  is  so  treated  by  DeCandolle  (Prodr.  5:  603.  1836)  and 
0.  E.  Schulz  (Bot.  Jahrb.  50,  Suppl. :  183. 1914).  At  Leipsic  I  failed 
to  find  an  authentic  specimen  of  B.  tenuifolia.  B.  elongata  Tausch 
appears  likewise  unrepresented  by  an  authentic  specimen  to-day, 
but  the  description  given  by  Tausch,  as  also  his  context,  leaves  no 
doubt  as  to  the  identity  of  B.  elongata  with  B.  bipinnata.  The 
various  specimens  examined  of  Kotschy  79,  the  basis  of  Bidens 
Kotschyi,  show  mostly  a  variant  of  B.  bipinnata  in  the  direction  of 
B.  biternata  var.  glabrata;  indeed,  that  at  Kew  (not  the  type)  is  very 
clearly  B.  biternata  var.  glabrata. 

J.  D.  Hooker  (loc.  cit.)  reduced  B.  bipinnata  to  varietal  rank 
under  B.  pilosa,  a  treatment  not  generally  accepted  by  botanists  since 
then.  True  it  is  that  Trimens  (Fl.  Ceyl.  3:  41.  1895)  and  also  Th. 
Cooke  (Fl.  Bombay  Pres.  2:  44.  1904)  regarded  Hooker's  "variety" 
as  "scarcely  worth  distinction"  from  B.  pilosa.  But  this  was  before 
the  researches  of  0.  E.  Schulz  had  placed  B.  pilosa,  B.  biternata, 
and  B.  bipinnata  upon  a  firm  footing  as  to  definite  fruiting  and 
foliage  characters.1 

Of  Bidens  bipinnata  var.  minor  Memm.  I  have  seen  no  authentic 
material.  Memminger's  description  ("Very  delicate,  small,  10  cm. 
high,  in  dense  shade  on  rocks"),  however,  leaves  little  doubt  that 

1  Cooke  expressly  cited  Trimens'  conclusion,  agreeing  with  it.  Trimens,  in 
turn,  doubtless  was  influenced  by  Hooker's  grouping  of  B.  bipinnata  under  B. 
pilosa.  In  view  of  the  superficially  intermediate  leaves  of  B.  biternata  (B.  Wal- 
lichii),  a  species  very  common  in  British  East  India,  but  erroneously  equated  by 
Hooker  with  B.  bipinnata,  it  was  only  natural  that  Trimens  should  have  felt  that 
B.  bipinnata  equaled  B.  pilosa.  Had  he  studied  the  fruiting  characters  as  did 
O.  E.  Schulz  later,  he  would  have  concluded  otherwise.  Curiously  enough,  Hooker, 
in  publishing  his  work,  relied  here  upon  the  erroneous  treatment  by  C.  B.  Clarke 
(Comp.  Ind.  141),  as  stated  elsewhere  (vide  sub  B.  biternata).  Clarke,  at  a  later 
date,  realized  his  own  error  and  stated  (on  herb,  label  for  H.  Collett  816,  Kew)  that 
"B.  Wallichii  DC.  [i.e.  B.  biternata  (Lour.)  Merr.  &  Sherff]  has  the  ray  yellow  (and 
smaller)  as  well  as  different  leaves  and  is  a  good  species.  C.  B.  Clarke.  May  1894."

In  its  slightly  dilated  outer  involucral  bracts  this  variety  makes 
an  approach  toward  Bidens  pilosa  L.  The  general  aspect  of  the 
plant  is  at  once  that  of  the  South  American  B.  subalternans  DC.  and 
of  the  Old  World  B.  biternata  (Lour.)  Merr.  &  Sherff,  from  both  of 
which  it  differs  sharply  in  its  achenes.

Type  specimen:  Collected  by  Menyhart,  No.  1110,  not  abundant, 
in  shady  places  at  St.  Joseph,  Boruma  (Mburuma;  Boroma;  about 
400-500  kilometers  above  Tete  on  Zambesi  River),  Northern  Rho- 
desia, April,  1892  (U.V.). 

Distribution:  From  Boruma,  Northern  Rhodesia,  southwestward 
up  the  Zambesi  River  to  the  District  of  Sebungwe  (Sebungu), 
Southern  Rhodesia;  also  north-northwestward  to  the  Tschari 
(Schari,  Shari,  Chari)  River,  Tschad  (Tchad,  Chad)  Lake  region, 
some  3,000  kilometers  distant. 

Specimens  examined:  Aug.  Chevalier  2816,  along  the  Tschari 
River,  Tschad  Lake  region,  Sudan,  October  26,  1899  (Berl.);  F. 
Eyles  (cult,  e  seminibus  ab  R.  W.  Jackio  lectis,  alt.  750  meters,  Distr. 
Sebungwe,  Southern  Rhodesia,  November,  1920;  Kew);  ex  Hort. 
Vindobon.  (cult,  e  seminibus  Menyhartii  numeri  1110;  U.V.,  2  sheets) ; 
Menyhart  1110.  (type,  U.V.) ;  Walter  Robyns  2004,  alt.  930  meters, 
border  of  sandy  beach  of  Lake  Moero,  Pweto,  Belgian  Congo,  April 
18,  1926  (Bruss.;  nom.  indig.,  Kasokopia). 

The  Chevalier  specimen  listed  had  been  determined  by  0.  E. 
Schulz  as  his  Bidens  Engleri,  and  in  fact  was  cited  by  him,  as  was 
also  the  nomen  B.  pilosa  var.  pauciflora,  for  that  species  at  the 
time  of  his  original  description  (Bot.  Jahrb.  50,  Suppl.:  186.  1914). 
Recently,  I  have  been  privileged  to  study  not  only  Schulz's  type  of 
B.  Engleri  (Berl.),  but  also  excellent  specimens  of  duplicate  material 
(Boiss.;  Mus.  V.,  etc.).  These  all  agree  in  having  plants  of  low 
stature  (2-3  dm.  high),  the  leaves  practically  all  undivided,  the 
heads  discoid;  the  exterior  involucral  bracts  only  about  3  or  4, 
spatulate,  serrulate-ciliate,  1-2  mm.  long;  the  inner  bracts  2-5  times 
as  long,  often  rounded  at  apex;  the'achenes  all  glabrous,  parallel- 
sided  through  most  of  their  length  and  thus  oW<mg(-linear,  obcom- 
pressed,  about  1  mm.  wide.  With  this  material  the  Chevalier  and 
Menyhart  specimens  were  compared  and  were  seen  to  differ  sharply 
as  follows:  Height,  4-7  dm.,  leaves  3-5-parted,  heads  subradiate; 
the  exterior  involucral  bracts  6-8,  linear  and  mostly  narrowed  above, 
ciliate  with  slender  hairs  instead  of  with  minute  serrulations,  3-8

mm.  long;  the  inner  bracts  mainly  1.1-2  times  as  long,  subacute  at 
apex;  the  outer  achenes  frequently  hairy,  all  narrower  and  gradually 
attenuate  upward,  distinctly  tetragonal,  only  0.5-0.8  mm.  wide. 

A  question  at  once  arose  from  the  fact  that  the  Chevalier  and 
Menyhart  specimens  had  come  from  localities  3,000  km.  or  more 
apart,  while  the  type  material  of  B.  Engleri  had  come  from  a  point 
more  or  less  intermediate  (about  6°-8°  N.  Lat.  and  26°-28°  E.  Long. 
In  my  judgment  morphological  considerations  outweighed  those 
as  to  geographical  distribution  and  appeared  to  compel  a  segregation 
of  the  Chevalier  and  Menyhart  (and,  when  later  found,  the  Eyles 
and  Robyns)  specimens  as  a  species  distinct  from  B.  Engleri. 

The  name  cylindrica  alludes  to  the  shape  of  the  flowering  heads 
which,  in  the  two  specimens  cultivated  from  achenes  of  Menyhart 
1110,  are  notably  cylindric.

In  describing  Bidens  cognata,  Greene  (loc.  cit.)  stated  that  it  was 
"allied  to  B.  heterosperma."  He  then  proceeded  to  differentiate  it 
from  that  species,  which  was  very  easy  because  B.  heterosperma  was 
so  unlike  it.  Here,  as  in  certain  other  cases  (cf.  Sherff,  Bot.  Gaz.

ing the  plant  with  the  wrong  species  and  then  founding  a  new  species 
upon  the  points  of  dissimilarity.  His  type  material  (0.  B.  Metcalfe

Gray,  with  the  type  of  which  it  is  connected  by  a  number  of  the

Capitula  pauca  (±3),  subcorymbose  ad  caulis  apicem  disposita 
pedicellis  subsparsim  pilosis  subtenuibus  3-5  cm.  longis,  forsitan 
discoidea,  demum  circ.  1.4  cm.  lata.  Involucri  bracteae  subaequales 
extrinsecus  pilis  gracillimis  albidis  longis  hispidae,  exteriores  circ. 
4-6  elongato-lineares  acutae  circ.  5-7  mm.  longae;  interiores  oblongo- 
ovatae.  Flores  ligulati  non  visi.  Paleae  nunc  late  nunc  anguste 
oblongae,  apice  plus  minusve  obtusae.  Achaenia  atra,  plana,  lineari- 
oblonga,  supra  rarius  angustata,  marginibus  ventreque  valde  tergo 
pluristriato  aegre  erecto-setosa  setis  e  tuberculis  ortis,  corpore  7-8 
mm.  longa  et  0.6-0.8  mm.  lata,  apice  erecte  setosa  et  biaristata 
aristis  brunneis  antrorso-hispidulis  circ.  0.6-0.8  mm.  longis. 

Type  specimen:  Collected  by  H.  Scaetta,  No.  2272,  at  altitude 
of  about  1,850  meters,  Mt.  Bohanga,  Ruanda  District,  German  East 
Africa  (Mus.  Cong.,  2  sheets). 

Distribution:  Ruanda  District,  German  East  Africa. 

Specimens  examined:  Scaetta  2272  (2  type  sheets,  Mus.  Cong.). 

The  stems  are  especially  elongate,  nudate,  and  mostly  less  than 
2  mm.  thick,  appearing  when  dry,  therefore,  more  or  less  like  straws. 
Apparently  closest  to  Bidens  paupercula,  which  differs  in  having 
more  elongate  achenial  bodies,  retrorsely  barbed  aristae,  etc.

dilatata  et  semper  biaristata  aristis  tenuibus  retrorsum  hamosis 
1.2-2.5  mm.  longis. 

Type  specimen:  Collected  by  Ad.  Stolz,  No.  1442,  in  forest  at 
altitude  of  900  meters,  Kyimbila,  Nyassaland,  July  22,  1912  (Berl., 
2  sheets). 

Distribution:  Nyassaland  to  southeastern  Belgian  Congo. 

Specimens  examined:  J.  Bequaert  302,  Elisabethville,  Katanga, 
Belgian  Congo,  April  4,  1912  (Bruss.,  2  type  sheets  of  B.  ciliata 
DeWild.);  F.  A.  Rogers  10956,  Elisabethville,  Katanga,  May,  1914 
(Rog.);  Stolz  1442  (type,  Berl.,  2  sheets:  cotypes,  Cop.;  Del.;  Mun.; 
Mus.  V.). 

Unlike  most  other  African  species  of  Bidens,  this  possesses  close 
affinities  with  B.  bipinnata  L.  and  B.  parviflora  Willd.  The  type 
specimens  were  small  plants,  but  the  cotypes  and  other  specimens 
later  examined  were  much  larger  and  better  developed.  From  these 
and  also  from  the  more  robust  material  collected  by  Rogers  in  the 
type  locality,  the  original  description  has  been  amplified.  B.  ciliata

A  species  not  easily  confused  with  any  other  Asiatic  species. 
Known  to  Messerschmid  as  early  as  1739  (or  earlier),1  it  was  not 
properly  published  until  1809.  In  that  year  Willdenow  gave  a  technical 
description  of  it,  citing  as  an  equivalent  the  name  B.  macrosperma 
Fisch.,  which  had  been  published  without  description  in  1808.  I 
have  seen  very  old-looking  sheets  of  material  (e.g.,  Mus.  V.)  with 
merely  the  name  macrosperma  on  the  label  and  these  match  perfectly 
the  Willdenow  specimens  (Willd.)  of  B.  parviflora.  Poiret's  private 
specimen  of  B.  pauciflora  Poir.  (Par.)  likewise  matches  the  Willdenow 
specimens.  Desfontaines'  B.  multifida  was  merely  a  nomen,  listed 
as  being  one  used  at  the  Paris  Botanical  Garden,  and  was  equated 
by  Desfontaines  himself  with  B.  pauciflora  Poir.  Certain  very  old- 
looking  sheets  of  material  labeled  Bidens  multifida  Desf.,  still  extant 
in  herbaria  (e.g.,  Mus.  V.)  are,  furthermore,  merely  B.  parviflora 
Willd.  Turczaninow's  original  specimen  of  his  B.  Messerschmidii  is 
in  the  DeCandpllean  Prodromus  Herbarium  (Del.)  and  likewise 
is  B.  parviflora  Willd.

0.  E.  Schulz,  in  his  special  study  of  Bidens  chinensis  Willd.  and 
related  species  (Bot.  Jahrb.  50,  Suppl.  178.  1914),  appears  to  have 
overlooked  the  Coreopsis  biternata  of  Loureiro,  published  with  a 
description  in  1790,  some  fourteen  years  earlier  than  the  date  of 
Willdenow's  work.  In  view  of  the  many  difficulties  involved  in 
the  interpretation  of  some  of  Loureiro's  species,  until  recently  I 
myself  have  refrained  from  attempting  final  disposition  of  his  names. 
At  last,  however,  these  difficulties  have  been  overcome  and  a  cer- 
tain and  conclusive  treatment  becomes  possible. 

Loureiro  described  two  species  of  Bidens,  namely  B.  pilosa  L. 
and  5.  bipinnata  L.,  and  two  of  Coreopsis,  namely  C.  leucorrhiza  Lour, 
and  C.  biternata  Lour.  The  first  two  may  be  passed  over,  since  they 
were  admittedly  not  new  species  and  since  the  known  occurrence 
of  these  two  species  in  the  region  mentioned  by  Loureiro  (Cochin- 
China  and  China)  tends  to  confirm  the  identity  of  the  Loureiro 
plants.  The  third  species,  Coreopsis  leucorrhiza  Lour.,  has  recently 
been  referred  (Bot.  Gaz.  86:  443.  1928)  to  Bidens  pilosa  var.  minor 
(Bl.)  Sherff. 

The  fourth  species,  C.  biternata  Lour.,  was  known  to  Loureiro 
under  the  Annamese  dialectic  name  Ca  ap  chioc,1  and  he  stated  that 

1  Loureiro  "lived  at  Hue  for  approximately  thirty-five  years,  this  town  being 
the  ancient  capital  of  the  kingdom  of  Cochin  China,  now  a  part  of  French  Indo- 
China.  I  assume  that  the  limits  of  the  old  kingdom  of  Cochin  China  were  approxi- 
mately the  limits  of  the  Province  of  Annam  Anam,  to-day,  in  French  Indo-China. 
On  leaving  Hue,  Loureiro  proceeded  to  Canton  and  spent  two  or  three  years  there 
before  proceeding  to  Lisbon. .  .  .  Loureiro  tried  to  indicate  in  his  native  names  as 
between  Annamese  (indicated  by  the  letter  'a')  and  Chinese  names  (really  in 
Mandarin)  by  the  letter  'b'.  .  .  by  China  he  means  the  general  vicinity  of  Canton 
in  Kwangtung  Province.  .  .  .  Generally  speaking:  I  am  of  the  opinion  that  most 
of  his  work  was  done  on  Cochin  China  specimens,  chiefly  for  the  reason  that  he 
resided  so  long  in  Cochin  China  and  for  a  comparatively  brief  time  in  Canton; 
and  the  conditions  in  Canton  at  the  time  of  his  visit  were  such  that  it  would  have 
been  impossible  for  him  to  visit  any  regions  outside  of  the  immediate  vicinity  of 
the  city" Dr.  Elmer  D.  Merrill  in  lit.  April  22,  1929.

it  grew  in  fields  near  Canton,  China.  His  description  follows: 
"Differ,  spec.  Cor.  foliis  biternatis,  ovato-lanceolatis,  serratis:  pani- 
cula  diffusa:  radio  sexfloro.  Habitus  et  notae.  Caulis  herbaceus, 
3-pedalis,  erectus,  4-gonus,  4-sulcatus,  integre  luteus:  panicula  sparsa, 
terminali.  Radii  corollae  6,  neutrae.  Pappus  bicornis,  ramosus. 
Receptaculum  planisculum,  nudum." 

His  character  for  the  foliage,  biternatis,  shows  at  once  that  he 
was  dealing  with  the  same  plant  that  Willdenow  treated  under  the 
name  Bidens  chinensis.  His  "pappus  bicornis"  was  doubtless  merely 
one  of  the  numerous  errors  for  which  his  descriptions  were  noted.1 
His  "receptaculum  ....  nudum"  probably  was  based  upon  capitula 
that  had  shed  their  achenes  and  chaff  scales,  for  just  previously,  in 
his  generic  description  of  Coreopsis,  he  had  said  "recept.  paleaceum." 

In  my  monographic  study  of  Bidens,  I  have  found  a  considerable 
number  of  specimens  from  the  general  region  traversed  by  Loureiro 
which  are  listed  among  the  foregoing  "Specimens  examined."2 

Recently  I  was  supplied  by  Dr.  Elmer  D.  Merrill  with  an  excerpt 
from  the  manuscript  of  his  "A  Commentary  on  Loureiro's  Flora 
Cochinchinensis"  (since  published;  vide  Trans.  Amer.  Phil.  Soc.  n. 
ser.  24:  391.  1935).  Merrill,  too,  had  concluded  Coreopsis  biternata 
Lour,  to  be  the  same  as  Bidens  chinensis  Willd.  Since  then,  he  has 
assisted  with  various  desired  data  and  has  recently  joined  me  in 
publishing  the  new  combination  which  this  conclusion  made  necessary. 

In  a  former  article  (Bot.  Gaz.  61:  499.  1916)  I  have  remarked 
upon  the  good  historical  summary  for  this  species,  with  a  compre- 
hensive list  of  synonyms,  presented  by  0.  E.  Schulz  (Bot.  Jahrb.  50. 
Suppl.:  176.  1914).  It  is  seen  that  the  history  of  B.  biternata  goes 
back  as  far  as  Plukenet's  Phytographia  of  1691.  Plukenet's  plant 
had  been  received  from  D.  Petiver,  to  whom  it  had  been  brought 
from  China.  The  illustration  later  presented  by  Dillenius  (Bidens 
latifolia  hirsutior,  semine  angustiore,  radiato — Hort.  Eltham.  51, 
pi.  43.  1732)  was  deceivingly  like  B.  biternata,  although  with  leaves 
somewhat  narrower.  The  plant  of  the  Dillenian  Herbarium  at  Oxford 
("no.  43.51.51")  is  found  to  be  really  Bidens  pilosa  L.,  however, 
and  so  the  Dillenian  name  must  be  excluded  from  synonymy.3 

1  Occasionally  the  pappus  is  tricornis  and  it  may  very  well  be  that  he  had  so 
spelled  the  word  on  sending  it  to  the  printer  for  the  first  edition.    In  any  case  this 
error  was  not  corrected  in  the  second  edition. 

2  These  mostly  bear  my  herbarium  determination,  Bidens  chinensis  Willd.  or, 
incorrectly  as  to  Linnaeus  (see  discussion  in  text),  (L.)  Willd. 

3  In  August,  1924,  I  examined  Dillenius'  plant  at  Oxford  very  carefully.    The 
two  somewhat  biternata-\ike  leaves  which,  in  the  illustration,  had  caused  0.  E. 
Schulz,  myself,  and  others  to  refer  the  Dillenian  plate  to  B.  biternata  (or  its  syn- 


398  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

The  Rumphius  plate,  showing  an  entire  fruiting  plant  from  Amboina, 
or  a  neighboring  island,  is  very  good  and  matches  precisely,  in  its 
individual  aspect,  many  of  the  plants  collected  in  that  general  region 
in  recent  years.  Varietally,  however,  it  might  profitably  be  regarded 
as  different  from  much  of  the  B.  biternata  in  other  parts  of  the 
Eastern  Hemisphere,  were  there  not  here  so  many  intergradations 
as  to  make  varietal  distinctions  in  probably  all  cases,  except  for  var. 
glabrata,  impossible.  We  may  add  that  Rumphius'  plate  is  partic- 
ularly important  because  it  is  directly  to  that  plate  that  Willde- 
now's  two  synonyms  lead  (Willdenow  did  not  cite  B.  pilosa  var. 
chinensis  L.  as  a  synonym!). 

In  several  hundred  herbarium  determinations  I  have  unfortu- 
nately followed  0.  E.  Schulz  in  appending  "(L.)  Willd."  to  the  name 
there  used  (B.  chinensis).  As  even  Schulz  admitted,  the  varietal 
name  as  first  published  by  Linnaeus  in  the  Mantissa  (p.  281.  1771) 
was  based  upon  cultivated  material,  which,  from  the  Linnean  descrip- 
tion, was  doubtless  B.  pilosa  var.  minor  Sherff.  The  Linnean  Her- 
barium has  several  sheets  pinned  together  in  the  Bidens  pilosa  cover. 
One  is  labeled  "Bidens  5  pilosa";  a  second,  "Bidens  pilosa  variety"; 
a  third,  "HU  Radio  albo" ;  a  fourth  has  on  its  back,  "Rumph.  amb.  6 
t.  15."  This  fourth  sheet  has  a  plant  with  five  heads,  two  of  them 
fruiting,  and  a  separate  leaf  at  one  side.  The  leaf  is  5-partite,  with 
the  two  basal  leaflets  each  2-partite  because  of  an  ovate  leaflet  on  the 
lower  side.  Examination  of  this  material  in  1914  and  again  in  1924 
convinced  me  that  this  fourth  sheet  is  of  a  merely  freakish  form  of 
B.  pilosa  var.  minor,  and  not  B.  chinensis  Willd.  Hence  Linnaeus' 
name  may  well  be  left  out  of  consideration  here,  and  Willdenow,  who 
fortunately  cited  only  the  Systema  Vegetabilium  (ed.  13,  p.)  610 1  for 
his  basis,  may  properly  be  given  sole  credit. 

As  stated  previously  (Bot.  Gaz.  loc.  cit.),  the  figure  in  Plukenet's 
Phytographia  was  cited  by  Tausch  (Flora  19 :  395. 1836)  for  his  Bidens 
Cicutaefolia.  A  study  of  his  context  (some  of  which,  unfortunately, 
was  not  included  in  the  manuscript  copy  before  me  at  the  previous 
writing)  shows  that  Tausch  primarily  was  describing  several  species 
of  Bidens  cultivated  in  gardens  under  the  name  of  B.  bipinnata  and 
that  then,  in  the  case  of  his  B.  Cicutaefolia,  he  added  the  Plukenet 
reference.  Under  these  circumstances,  the  Plukenet  reference  may 

onym,  B.  chinensis),  were  detached  from  the  main  specimen  and  might  have 
belonged  to  another  specimen.  At  any  rate,  the  main  specimen  was  very  clearly 
and  positively  Bidens  pilosa  L. 

1  A  work  that  omits  Linnaeus'  varietal  name  chinensis  published  three  years 
earlier  and  rests  the  variety  directly  upon  Rumphius'  Agrimonia  molucca.

properly  be  discarded  and  Tausch's  description  itself,1  which  con- 
flicts with  B.  biternata  as  to  achenes,  be  used  instead.  This  course 
led  me  some  time  ago  to  the  conclusion  that  Tausch's  B.  Cicutaefolia 
was  probably  a  mere  form  of  B.  bipinnata  L.,  a  conclusion  since 
confirmed  by  examination  of  Tausch's  own  specimen  (cult.)  of 

B.  Cicutaefolia  (Lps.). 

The  species  B.  biternata  is  usually  distinguished  easily  from 
typical  B.  pilosa  by  the  leaves,  the  lower  leaflets  in  the  former 
commonly  being  tripartite,  not  simple.  The  external  involucral 
bracts  and  the  achenes  also  are  usually  distinct. 

Gaudichaud's  B.  peduncularis,  collected  on  Freycinet's  voyage, 
at  the  Island  of  Rawak  of  the  Molucca  Islands,  is  B.  biternata.  It  is 
of  interest  as  having  come  from  the  same  group  of  islands  as  Rum- 
phius'  Agrimonia  molucca.*  All  through  that  region  B.  biternata  is 
common. 

Miquel  (Fl.  Nederl.  2:  78. 1856)  refers  Agrimonia  molucca  Rumph. 
to  B.  peduncularis  Gaud,  "(nisi  ad  praec.  /3.  [i.e.,  B.  Wallichii  var. 
bimensis  Miq.])."  It  is  true  that  Miquel  erroneously  equated  B. 
sandvicensis  Less,  with  B.  peduncularis  Gaud,  but  in  this  he  doubt- 
less was  merely  following  DeCandolle's  earlier  treatment  (Prodr.  5: 
598.  1836).  Interesting  it  is,  then,  to  find  that  as  early  as  1856 
Miquel  had  come  almost  to  the  point  of  synonymizing  the  two 
names  of  Moluccan  plants  with  each  other  and  with  B.  Wallichii  DC. 

Of  Bidens  Wallichii  DC.  many  authentic  specimens  are  extant 
today  and  they  all  are  seen  to  be  very  definitely  B.  biternata.  Thus, 
for  example,  six  uniform  sheets  of  material  occur  in  Berlin  (Berl.). 
These  were  collected  by  Wight,  Prone,  Tavoy,  etc.,  and  all  are  B. 
biternata.  They  all  are  of  the  old  Wallich  distribution  No.  3189, 
cited  by  DeCandolle  for  his  B.  Wallichii.  C.  B.  Clarke  (Compos. 
Ind.  141.  1876)  reduced  B.  Wallichii  to  a  variety  of  B.  pilosa  L. 
but  later,  on  a  herbarium  sheet  in  Kew  Herbarium,  admitted  his 
error  in  so  doing.3 

B.  Wallichii  var.  bimensis  Miq.  was  described  from  a  specimen 
collected  by  Rheinwardt  on  the  Island  of  Bima,  considerably  to  the 

1  "Foliis  bipinnatisectis  glabris,  laciniis  ovatis  dentatis,  caule  stricto,  floribus 
corymbosis  subradiatis,  involucre  appresso,  achaeniis  erectis  2-aristatis." 

2  For  further  data  see  under  B.  sandvicensis  Less.  (p.  123,  footnote  1). 

3  On  the  herbarium  label  for  H.  Collett  816,  Clarke  wrote,  "I  erred  about  these 
two  Indian  Bidens  ([sic]  in  my  Comp.  Indicae)  and  Sir  J.  D.  Hfooker]  unfortu- 
nately 'followed'  me. 

"Bidens  pilosa  Linn,  is  B.  leucantha  Willd.  and  has  the  ray  white.  B.  Wallichii 
DC.  has  the  ray  yellow  (and  smaller)  as  well  as  different  leaves  and  is  a  good  species.

southwest  of  the  Molucca  Islands.  From  its  description,1  it  appears 
to  differ  in  no  important  respect  from  ordinary  B.  biternata. 

B.  chinensis  f.  simplicifolia  0.  E.  Schulz  was  based  on  Henry's 
No.  388  from  the  Province  of  Hupeh,  China.  It  is  merely  a  small, 
poorly  developed  form.  The  leaves  are  simple,  as  happens  also  in  B. 
pilosa,  B.  tripartita,  and  many  other  similar  species  when  the  growth 
conditions  are  poor.  One  may  well  doubt  the  wisdom  of  assigning 
indiscriminately  to  formal  or  varietal  rank  the  many  impoverished 
or  otherwise  retarded  forms  of  this  nature  that  are  found  repeatedly 
among  herbarium  specimens.2 

Bidens  pinnata  Noronha  (Verh.  Batav.  Gen.  5  [ed.  1.]  Art.  IV[?] 
8.  1790)  is  listed  without  description  but  with  the  Java  synonym 
Harruga.  It  probably  was  either  B.  biternata  or  B.  pilosa  var. 
minor,  both  of  these  plants  being  known  in  Java,  probably  without 
distinction,  under  the  name  Harruga. 

LeVeill£  (loc.  cit.)  cited  as  the  type  for  B.  Robertianaefolia  LeVl. 
&  Vant.,  a  plant  collected  in  Corea  by  Taquet:  Island  of  Quelpaert, 
in  uncultivated  places  at  Hongno,  September  23,  1908.  There  exist 
fine  specimens  with  these  data  in  Geneva  and  Berlin  (Taquet  969, 
Del.;  Berl.).  They  are  B.  biternata. 

Plants  by  Bretschneider,  David,  etc.,  from  the  neighborhood  of 
Peking,  China,  display  a  remarkable  approach  or  transition  through 
their  more  decompound  and  membranaceous  leaves  and  their  fre- 
quently narrower  and  fewer-flowered  heads  to  B.  bipinnata  L.  (or 
are  even  suggestive  of  the  North  American  B.  Bigelovii  Gray  and  B. 
leptocephala  Sherff).  A  slightly  similar  approach  is  made  rarely  by 
plants  collected  elsewhere  (e.g.,  Macgillivray  63,  Lizard  Isl.).

In  proposing  as  a  new  species  his  Bid-ens  lasiocarpa,  Schulz  empha- 
sized (in  key,  op.  cit.  87)  the  fact  that  the  outer  achenes  are  more  or 
less  recurved  and  commonly  very  densely  hirtous,  but  this  character 
is  present  equally  well  in  the  type  material  of  B.  biternata  var.  glabrata 
and  its  f.  abyssinica,  where  it  seems  to  have  been  overlooked  by  him. 
Moreover,  B.  lasiocarpa  has  long  achenes,  as  in  the  type  material 
of  var.  glabrata  and,  as  a  whole,  is  too  closely  connected  by  inter- 
mediate forms  in  the  herbaria  to  rank  as  a  separate  species.  B.  lasio- 
carpa appears  to  bear  somewhat  the  same  relationship  to  the  var. 
glabrata  as  is  borne  by  the  peculiar  local  form  found  about  Peking, 
China,  cited  under  the  species  proper,  to  the  species  itself.  In  both 
cases  there  is  a  gradation  of  the  foliage  toward  the  more  membrana- 
ceous  and  more  decompound  type  possessed  by  Bidens  bipinnata  L.

Type  specimen:  Collected  by  Wilhelm  Schimper,  No.  337,  in 
stony  places  on  the  mountains  and  in  the  valleys  near  Adowa  (Adoa) 
and  everywhere  in  front  of  Djeladjeranne  (Tche'latche'kanne'  fide

ladscheranne),  Abyssinia,  September  19,  1837  (Par.). 

Distribution:  With  the  var.  glabrata  and  much  more  common. 

Specimens  examined:1  Chiovenda  1120,  Gondar,  Prov.  Amhara,

3  sheets;  Mo.;  Mun.;  Mus.  V.;  U.V.). 

Some  of  Schimper's  original  specimens,  on  which  were  founded 
the  names  Bidens  abyssinica,  B.  abyssinica  var.  quadriaristata,  and 

B.  quadriseta,  are  densely  hairy  forms  with  tripartite  leaves  and 
conspicuously  large  fruiting  heads.     In  leaf  characters  they  might 
be  confused  with  B.  pilosa  L.;  their  achenes  and  involucral  bracts, 
however,  are  very  distinct.    Some  cotypes  of  "B.  abyssinica"  (Brit., 
etc.)  show  leaves  more  incisely  toothed  or  lobed  and  approaching 
more  or  less  closely  those  of  B.  biternata  proper.   The  fruit  characters 
sometimes  seem  too  distinctive  to  warrant  reducing  "B.  abyssinica" 
to  subordinate  rank  under  B.  biternata  as  proposed  by  0.  E.  Schulz, 
but  the  great  number  of  intergradations  observed  in  various  her- 
barium specimens  appears  to  compel  some  such  course. 

The  varietal  name  incisifolia  was  given  originally  to  specimens 
of  Schimper  2328,  described  (Oliver,  loc.  cit.)  as  having  "rather 
more  deeply  cut  lobes."  The  authentic  sheet  of  this  number  at  Kew, 
however,  marked  "Fl.  Afr.  Trop.  iii  p.  393,"  has  none  of  its  leaves 
incisely  toothed  to  a  noticeable  degree. 

1  Here  belong  also  the  majority  of  the  specimens  which  are  cited  on  p.  401, 
footnote  2.

THE  GENUS  BIDENS  405 

B.  abyssinica  var.  quadriaristata  Hochst.  ex  Schweinf.  was 
published  without  description,  but  based  upon  W.  Schimper  729, 
ad  Gageros,  September  16,  1854,  etc.  I  have  not  seen  this  number, 
but  the  data  given  by  Schweinfurth  are  essentially  the  same  as  those 
for  Schimper  105  and  2324  already  cited.  Oliver  and  Hiern  (in 
Oliv.  loc.  cit.)  cited  this  varietal  name  as  a  synonym  for  Bidens 
quadriseta,  but  of  course  did  not  thus  validate  it  as  a  varietal  name, 
nor  did  the  varietal  nomen  incisi/olia  receive  valid  publication. 

Bidens  laciniata  Schz.  Bip.  ex  Schweinf.  was  a  nomen  applied  to 
Kotschy  325.  The  material  in  Schultz  Bipontinus'  private  herbarium 
(Par.)  had  been  received  from  the  Vienna  Botanical  Garden.  This 
and  also  the  more  ample  specimen  in  Vienna  (Mus.  V.)  are  the 
f.  abyssinica.

Type  specimen:  Collected  by  Georg  Schweinfurth,  No.  2596,2  in 
forest  called  Genena,  near  Seriba  Ghattas,  District  of  Jur  (Djur), 
Province  of  Bahr-el-Ghazal,  English-Egyptian  Sudan,  November  8, 
1869  (Berl.). 

Distribution:  Known  only  from  type  locality  in  Province  of 
Bahr-el-Ghazal,  English-Egyptian  Sudan. 

Specimens  examined:  Schweinfurth  2596  (type,  Berl.:  cotypes, 
Boiss.;  Mun.;  Mus.  V.;  Par.). 

An  African  species  comparable  to  Bidens  tenera  of  northern 
South  America.  The  plants  of  the  type  collection  all  are  less  than 
3  dm.  high,  and  practically  all  the  leaves  are  undivided.  Hispid 
outer  achenes  are  lacking  and  the  exterior  involucral  bracts  are 
mostly  about  3  or  4  in  number,  1-2  mm.  long  and  spatulate,  with 
the  margin,  except  near  the  base,  minutely  serrate.  The  achenes, 
which  tend  to  be  rather  parallel-sided  throughout  their  length  and 
hence  oblong-linear,  are  unique  in  appearance. 

With  B.  Engleri  Schulz  identified  an  apparently  different  form,

Distribution:  Known  only  from  Cuba  and  Bolivia. 

Specimens  examined:  Otto  Buchtien  4182,  alt.  1,300  meters,

Differs  from  the  species  proper  in  its  more  numerous  achenes, 
these  quadriaristate  and  upwardly  attenuated,  not  triaristate  nor 
almost  parallel-sided  throughout.  The  general  aspect  is  that  of  a 
thin-leaved  form  of  Bidens  pilosa  L.  as  to  foliage  and  of  B.  bipinnata 
L.  as  to  fruiting  heads. 

Bidens  tenera  var.  tetracera,  published  in  November,  1929, 
was  found  to  have  been  antedated  several  months  by  the  equivalent 
B.  Ekmanii  0.  E.  Schulz  and  its  so-called  var.  paucidentata,  both  of 
Cuba.  The  type  specimens  of  B.  Ekmanii  and  its  var.  paucidentata 
are  now  before  me  (through  the  kindness  of  Dr.  Gunnar  Samuelsson, 
Director  of  the  Botanical  Section  of  the  Natural  History  Royal 
Museum  of  Stockholm).  They  differ  mutually  to  an  insignificant 
extent,  nor  are  they  separable  from  the  South  American  specimens 
described  for  B.  tenera  var.  tetracera.

Type  specimen:  Collected  by  Edward  Palmer,  No.  756,  on  west 
side  of  Iron  Mountain,  vicinity  of  Durango,  State  of  Durango, 
Mexico,  October,  1896  (Gray). 

Distribution:  States  of  Sonora  and  Chihuahua  to  State  of 
Mexico,  Mexico. 

Specimens  examined:  Berlandier  875,  around  City  of  Mexico, 
Federal  District,  September  19,  1827  (Del.;  Par.;  type  collection  of 
Bidens  Anthriscoides  var.  angustiloba  DC.);  Edward  Palmer  612, 
vicinity  of  Durango,  State  of  Durango,  Mexico,  October,  1896 
(Berl.;  Boiss.;  Brit.;  Calif.;  Field,  2  sheets;  Gray;  Kew;  Mo.);  idem

Sonora,  Mexico,  September  23,  1934  (Field). 

At  the  time  that  this  species  was  described,  I  looked  upon  B. 
pilosa  L.,  B.  leucantha  (L.)  Willd.,  B.  bimucronata  Turcz.,  B.  odorata 
Cav.,  and  several  other  similar  forms  as  representing  distinct  species. 
B.  duranginensis,  therefore,  was  considered  to  be  a  distinct  form  and 
clearly  entitled  to  specific  rank.  Since  then,  examination  of  a  vast 


410  FIELD  MUSEUM  OF  NATURAL  HISTORY— BOTANY,  VOL.  XVI 

amount  of  additional  material  from  European  herbaria  has  com- 
pelled the  conclusion  that  these  forms,  while  doubtless  seeming 
distinct  in  certain  localities,  at  various  places  in  their  distributional 
range  intergrade  so  thoroughly  that  all  hope  of  their  specific  segre- 
gation must  be  abandoned. 

This  being  true,  the  question  at  once  arises  whether  B.  duranginen- 
sis,  clearly  a  close  relative  of  B.  pilosa,  is  merely  another  of  B.  pilosa's 
many  varietal  manifestations,  or  whether,  like  B.  subalternans  DC., 
B.  biternata  (Lour.)  Merr.  &  Sherff,  and  several  other  pilosoid  forms, 
it  is  a  valid  species.  Certainly  it  is  very  close  in  flowers  and  fruits 
to  some  undisputed  forms  of  B.  pilosa  var.  radiata  Schz.  Bip.  C.  V. 
Hartman  113  (alt.  1,740  meters,  Las  Calabazas,  State  of  Sonora, 
Mexico,  October  9,  1890;  Gray;  Kew;  Penn.;  Phila.)  is  a  form  which 
in  some  specimens  appears  closer  to  the  young  state  of  B.  duranginen- 
sis  (as  typified  by  Palmer  612)  and  yet  in  others  appears  referable  to 
B.  pilosa  var.  radiata.  Aside  from  questionable  approaches  of  this 
kind,  I  have  been  unable  to  obtain  any  legitimate  basis  for  referring 
B.  duranginensis  to  synonymy  and  so  feel  compelled  to  retain  it  as  a 
separate  species.

Type  specimen :  Collected  by  Otto  Buchtien,  No.  815,  at  altitude 
of  3,300  meters,  below  Obraje,  southeast  of  La  Paz,  Bolivia,  May 
10,  1919  (Field,  2  sheets). 

Distribution:  Central  western  Peru  to  central  western  Bolivia. 

Specimens  examined:  Buchtien  815  (Field,  2  type  sheets:  cotypes, 
Field;  Gray;  Hamb.;  U.S.);  J.  F.  Macbride  2904,  alt.  about  2,400

river  bank,  eodem  loco,  April  12-May  3,  1922  (Field). 

A  species  with  somewhat  the  aspect  of  Cosmos.  The  flowering 
heads  are  those  of  Bidens,  however,  and  the  achenes  are  not  abruptly 
narrowed  above  into  a  neck  or  beak  as  in  typical  Cosmos.  The 
general  habit  bears  a  superficial  resemblance  to  that  of  certain 
branched  forms  of  the  North  American  Bidens  tenuisecta  Gray. 
Apparently  the  closest  ally  is  B.  andicola  var.  Cosmantha  L  Buch- 
tienii.  In  fact,  the  fruiting  characters  of  f .  Buchtienii  are  so  similar 
that  at  first  the  remarkable  habit  and  foliage  differences  in  B.  pseudo- 
cosmos  were  thought  attributable  to  the  fact  that  the  specimen  came 
from  a  larger  plant  than  the  observed  specimens  of  f.  Buchtienii. 
Additional  sheets  of  B.  pseudocosmos  were  found  later,  however, 
bearing  small,  entire,  fruiting  plants  and  even  here  both  the  habit 
and  the  foliage  distinctions  were  found  to  hold  true.

of  the  Hortus  Cliff ortianus  (p.  399.  1737).  The  first  and  only 
Hortus  Cliffortianus  synonym  given  was  the  Bidens  latifolia  hir- 
sutior,  semine  angustiore  radiato  of  Dillenius  (Hort.  Eltham.  51. 
pi.  43.  f.  51  and  1,  2,  3,  4-  1732).  Dillenius'  illustration  was  of  a 
specimen  still  extant  in  the  Dillenian  Herbarium  (Oxf.;  vide  p.  397, 
footnote  3),  which  is  a  slightly  abnormal  plant  (as  to  leaves)  of 
the  at  present  widely  known  and  accepted  Bidens  pilosa  L.  An 
excellent  and  more  typical  specimen  is  the  one  labeled  Bidens  pilosa 
in  the  official  Linnean  set  at  London  (Linn.). 

Distribution:  Widely  distributed  in  tropical  and  subtropical 
regions.  In  the  Western  Hemisphere  from  California  southeastward 
through  Mexico,  Central  America,  and  South  America  to  Chile, 
Argentina,  and  Uruguay,  also  in  the  West  Indies;  throughout 
Africa;  in  southeastern  Asia,  East  Indies,  Australia,  New  Zealand,

1  In  the  fruiting  stage,  specimens  of  the  minutely  radiate  var.  minor  fre- 
quently look  like  those  of  the  species  proper  and  it  is  more  than  likely  that  several 
collections  have  been  included  here  for  B.  pilosa  whereas  younger  material  (i.e.,  in 
its  minutely  radiate  state)  would  have  led  to  determination  as  var.  minor.  In  a 
number  of  cases,  I  had  determined  specimens  in  certain  herbaria  as  B.  pilosa  and 
later  found  the  duplicates  in  other  herbaria  to  be  characteristic  of  the  var.  minor. 
In  all  such  cases,  as  far  as  known,  the  collections  are  cited  under  that  variety.

The  pre-Linnean  setting  of  B.  pilosa  has  already  been  given  (vide 
sub  "Type  specimen").  Much  pertinent  material  will  be  found 
under  the  following  varieties  and  formae.  We  may  note  the  status 
of  certain  post-Linnean  synonyms  which  either  are  not  self-explana- 
tory or  else  do  not  receive  adequate  treatment  in  the  list  of  "Speci- 
mens examined." 

The  name  Bidens  reflexa  Link  has  been  variously  construed  by 
botanists  during  the  past  century.  This  is  doubtless  due  to  the  fact 
that  more  than  one  species  was  obtained  in  European  botanical 
gardens  from  supposedly  B.  reflexa  achenes  which  had  been  sent 
out  from  Berlin.  Thus,  some  of  the  B.  reflexa  material  in  the  Berlin 
Herbarium  is  5.  pilosa  L.,  while  in  the  Herbarium  of  the  University 
of  Halle,  for  example,  a  specimen  labeled  "Bidens  reflexa  Hort.  bot. 
Berol."  is  really  B.  serrulata  (Poir.)  Desf.  Fortunately  there  exists 
in  the  Berlin  Herbarium  an  original  specimen  by  Link.  Its  main 
label  says,  in  pencil,  "Bidens  sp.  Mexico."  In  ink  is  written  "reflexa 
m.  (Link)."  Another  label  says,  "Bidens  reflexa  Link  En.  2.  p.  306. 
Hort.  Bot.  Berol."  This  specimen  is  clearly  of  Link's  type  material 
and  matches  his  description,  except  that  he  erred  in  calling  it  a 
perennial,  for  it  is  an  annual.  It  is  nothing  more  than  B.  pilosa  L., 
to  which  it  must  be  referred. 

A  careful  study  of  Vellozo's  description  and  illustration  of  his 
B.  adhaerescens  shows  that  plant  to  be  none  other  than  B.  pilosa  L. 
His  description  of  the  capitulum  is  not  above  criticism.  In  the  short, 
abridged  description  at  the  beginning  we  read:  "floribus  terminalibus, 
discoideis,"  which  would  limit  the  description  to  B.  pilosa  proper. 
In  the  detailed  description  which  follows,  however,  we  read:  "Co- 

1  In  South  America  B.  pilosa,  in  common  with  such  related  species  as  B. 
Gardneri  and  B.  riparia,  is  often  called  Picao  (fide  F.  Hoehnei  et  al.). 

Concerning  the  value  of  B.  pilosa  as  a  forage  plant,  especially  for  horses  with 
intestinal  parasites,  and  as  a  plant  to  be  considered  in  connection  with  bananas 
for  cultivation,  vide  DeWildeman,  PI.  Util.  Inter.  556-557.  1903.

rollula  composite,  quandoque  radiata,  radis  octo  ligulatis,  albis." 
Thus  it  is  seen  that  he  really  included  also  the  plants  with  white 
rays,  forms  which  today  are  separately  treated  as  B.  pilosa  var. 
radiata  Schz.  Bip.1 

An  original  specimen  of  B.  ciliata  Hoffmgg.  is  in  the  collection 
of  the  younger  Reichenbach  at  the  Museum  of  Vienna.  It  was 
collected  by  Dr.  Hoffmannsegg.  It  is  a  nearly  glabrous  plant,  with 
discoid  heads,  and  is  typical  B.  pilosa  L.  In  the  original  description 
it  was  differentiated  from  B.  pilosa  because  of  its  polymorphous 
leaves,  a  character  of  no  value  here,  since  B.  pilosa  L.,  B.  subalternans 
DC.,  and  most  other  species  of  Bidens  display  a  noticeable,some- 
times  very  high  degree  of  foliar  polymorphism. 

A  sheet  bearing  two  type  specimens  of  B.  Montaubanii  Phil,  is 
in  Berlin  (Berl.).  These  were  received  from  Philippi.  They  display,  in 
the  narrowness  of  their  leaflets,  a  superficial  resemblance  to  certain 
specimens  of  the  South  American  B.  subalternans  DC.,  but  differ 
in  having  leaves  pinnate,  not  bipinnate,  and  the  achenes  2-aristate, 
not  2-4-aristate.  A  study  of  their  foliage,  achenes,  and  involucres 
shows  that  they  are  mere  foliage  forms  of  B.  pilosa  L.

Bidens  pilosa  L.  has  among  its  various  varieties  and  formae  a 
subradiate  variety,  widely  distributed  in  both  hemispheres.  This 
was  observed  by  Cassini.1  0.  E.  Schulz  (loc.  cit.)  has  employed  for 
it  the  varietal  name  dubia,  but  the  synonymous  Bidens  sundaica  Bl. 
had  already  been  reduced  to  varietal  rank  by  Hasskarl  (loc.  cit.)  in 
1844,  and  so  takes  precedence  over  the  name  dubia.  In  his  original 
description  Blume  (loc.  cit.)  listed  a  variety  minor,  "caule  foliisque 
humilioribus.  Crescit:  cum  praecedente  [i.e.,  B.  sundaica  ips., 
prope  Buitenzorg,  Java]."  Recently,  through  the  kindness  of  Dr. 
J.  W.  C.  Goethart,  Director  of  the  Royal  Herbarium  at  Leyden,  I 
was  privileged  to  examine  early  specimens  by  Blume  and  by  Jung- 
huhn,  from  Java.  Three  sheets  (Nos.  900,146  ...  72  pro  parte; 
900,146  ...  73;  900,146  ...  75)  bear  excellent  specimens  of  Blume's 
Bidens  sundaica.  A  few  minute  rays  are  present.  The  first  of  these 
sheets  bears  also  the  basal  part  of  a  specimen  (and  a  fruiting 
branch  which  probably  belonged  to  it),  labeled  unmistakably  in 
Blume's  own  handwriting,  "Bidens  Sundaica  Variet."  Dr.  Goethart 
(in  lit.)  very  properly  regards  this  as  "probably  type  of  var.  minor." 
The  one  fruiting  head  still  attached  to  the  rather  depauperate  basal 
portion  exactly  matches  the  others  on  the  B.  sundaica  plants.  A 
fourth  sheet  bears  still  more  depauperate  material  collected  by  Dr. 
Fr.  Junghuhn,  No.  357,  on  Mt.  Dieng,  Java.  It  is  labeled  in  Miquel's2 
handwriting  (fide  Goethartii  in  lit.)  as  a  depauperate  forma  of  B. 
sundaica  Bl.  Indeed,  its  three  specimens  (one  of  them,  in  flower, 

1  "...  les  calathides,  composees  d'un  disque  jaune  et  d'une  couronne  blan- 
chatre,   sont   larges   de  cinq  lignes.  . . .    Nous  ayons  observe,  pendant  plusiers 
annees,  des  individus  vivans  de  cette  espece,  cultives  au  Jardin  du  Roi,  et  nous 
avons  remarque  que  leurs  calathides  etoient  le  plus  souvent  incouronees,  rarement 
radiees.    Dans  ce  dernier  cas,  la  couronne  etoit  composee  de  cinq  a  sept  fleurs,  dont 
la  corolle  avoit  le  tube  court,  et  la  languette  courte,  large,  orbiculaire,  tridentee 
au  sommet,  multinervee,  a  nervures  jaunatres.  .  .  .  "- — Cassini,  loc.  cit. 

2  Miquel   (loc.  cit.)  cites  a  depauperate  form  collected  by  Junghuhn:  "B. 
leucantha  /3.  sundaica  Hassk.  I.e.  p.  100,  cujus  auctoritate  formam  hanc  alioquin 
satis  constantem  hue  retuli. — Formam  omnibus  partibus  depauperatam  in  elevati- 
oribus  montanis  Javae  insulae  el.  Jungh.  legit."

having  the  tiny  rays  very  evident)  are  so  obviously  a  merely  less 
developed  form  of  B.  sundaica,  that  few  if  any  authors  today  would 
seek  to  draw  any  distinctions. 

It  is  evident  that  the  actually  equivalent  name  minor,  given 
varietal  status  long  before  the  name  sundaica  was,  must  in  turn  take 
precedence,  supplanting  both  sundaica  and  dubia.1 

Blume's  description,  "B.  floribus  subradiatis  ..."  is  matched 
by  upwards  of  a  thousand  specimens  examined  in  the  past  few  years. 
It  is  represented  in  particular  by  several  of  Blume's  own  specimens 
(Brit.,  sub  numero  139;  Del.;  Par.;  Webb).  In  the  Delessert,  Paris, 
and  Webb  herbaria  the  heads  are  mostly  rayless,  perhaps  having  had 
the  few  rays  removed  in  previous  examinations.  The  foliage  aspect, 
however,  is  definitely  that  of  the  ordinary  subradiate  variety.  Fur- 
thermore, the  plant  at  the  British  Museum  of  Natural  History  is 
definitely  subradiate.2 

Even  earlier  than  Blume's  var.  minor  is  Bidens  pilosa  var.  chi- 
nensis  L.  Mantiss.  PI.  281.  1771,  a  name  omitted  from  the  foregoing 
list  of  synonyms.3  Linnaeus'  original  description  follows:  "Habitat 
in  India  orientali.  H.U.  Planta  simillima  Bid.  pilosae,  si  non 
eadem,  sed  radio  diversa.  Folia  supra  nuda,  sicca  ut  fere  scariosa. 
Flosculi  marginales  nivei  (nee  albi)  tamen  hermaphroditi  fertiles; 
primo  anno  sati  erant  conformes  flosculis  disci,  nee  majores,  altero 
anno  erant  radio  explanato  quinquefioro  piano  parvo.  Semina  radii 
aristis  4.  s.  5,  quae  in  B.  pilosa  vulgari  radiis  2.  s.  3." 

It  is  seen  that  the  Linnean  plants,  in  the  first  year  of  their  sowing 
(they  were  annuals  of  course),  had  no  ray  flowers  and  thus  were 
typical  B.  pilosa.  In  a  subsequent  year,  five  small  rays  appeared. 
It  would  seem  that  if  Linnaeus'  observations  were  flawless,  and  not 
founded  upon  confused  forms,  the  reason  for  distinguishing  our 
minor  varietally  (i.e.,  its  constancy)  would  automatically  disappear. 
If  we  consider,  however,  the  color  of  the  rays  in  the  later  plants,  it 
is  seen  that  some  were  glistening-  or  snowy-white  while  some  were 

1  Cf.  O.  E.  Schulz  (Bot.  Jahrb.  50,  Suppl.  179.  1914),  ".  .  .  dagegen  gehoren 
B.  sundaicus  .  .  .  und  var.  minor  .  .  .  wahrscheinlich  zu  B.  pilosus  L.  var.  dubius 
(Cass.)  0.  E.  S."   In  herbarium  determinations,  I  have  not  differentiated  between 
forms  having  or  lacking  aristae  on  the  ovaries  of  the  ligulate  florets. 

2  In  my  cultural  observations  the  var.  minor  appeared  to  come  very  true  to  a 
given  type.    For  example,  in  some  two  dozen  plants  (Sherff  2043)  raised  in  1915 
from  achenes  on  specimens  sent  by  Mr.  St.  Ahnne  (Bot.  Gard.  Raoul,  Papeete, 
Tahiti),  the  hundreds  of  flowering  heads  had  uniformly  tiny,  distinctly  yellowish, 
ligulate  florets,  as  had  been  observed  on  the  parent  material.

other  shades.1  My  field  and  herbarium  observations  indicate  a 
pronounced  constancy  in  the  ray  color  for  any  one  collection  of 
plants  of  var.  minor.  Therefore,  it  appears  probable  that  some 
of  the  smaller-rayed  forms  of  B.  pilosa  var.  radiata  composed  at 
least  a  part  of  the  later  material  examined  by  Linnaeus.  His  her- 
barium affords  no  help  in  solving  the  matter.2  Surely,  there  is  so 
much  of  uncertainty  in  the  application  of  the  Linnean  concept  that 
it  appears  unwise  to  adopt  it  as  against  the  clear  and  certain  con- 
cept associated  with  the  varietal  name  minor.3 

Bidens  aurantiaca  Colenso  has  its  description  ("Florets  .  .  . 
small,  bright  dark  orange:  ray-few,  .  .  .  ")  supplemented  by  the 
authentic  Colenso  specimen  at  Kew.  This  has  the  one  flowering 
head  now  lacking  rays,  but  the  aspect  of  the  various  critical  struc- 
tures is  more  properly  that  of  the  variety  minor  than  of  B. 
pilosa  proper. 

Klatt's  type  of  B.  africana,  as  already  pointed  out  (Bot.  Gaz. 
85:  14.  1928),  was  a  plant  collected  by  Dr.  C.  Keller,  on  Reunion 
Island,  summer  of  1886.  The  herbarium  containing  the  type  was 
not  cited  nor  have  I  succeeded  in  locating  an  authentic  specimen. 
At  Gray  Herbarium  are  various  tracings  by  Klatt,  which  form  an 
important  part  of  the  Klatt  Herbarium  obtained  by  that  institution 
some  years  ago.  One  of  these  is  of  B.  africana.  The  plant  represented 
is  seen  to  be  widely  remote  from  B.  Lantanoides  Gray  and  B.  hawai- 
ensis  Gray,  with  which  Klatt  compared  it  in  his  original  description. 
The  tracing,  construed  with  Klatt's  description  ("  .  .  .  Die  eiformi- 
gen  Strahlbliiten  sind  2-3  mm.  lang  .  .  .  "),  shows  that  the  plant 
was,  beyond  all  reasonable  doubt,  merely  a  simple-leaved  form  of  B. 
pilosa  var.  minor.

ently the  only  permissible  way:  "snowy-white  (also,  not  white)." 

2  There  are  four  sheets  pinned  together;  one,  correctly  labeled  Bidens  pilosa; 
a  second,  labeled  "B.  pilosa  variety"  and  determined  by  me  as  B.  pilosa;  a  third, 
from  the  Hortus  Upsalensis,  with  merely  the  inscription   "Radio  albo,"   and 
belonging  to  B.  pilosa  var.  minor;  a  fourth,  with  the  inscription  (on  back  of  sheet, 
"Rumph.  amb.  6,  t.  15")  and  identified  by  me  as  B.  pilosa. 

3  It  may  be  noted  that  O.  E.  Schulz  has  likewise  declined,  in  his  writings  upon 
Bidens,  to  adopt  the  name  chinensis  for  this  variety.

1  Biologically  the  var.  radiata  is  best  typified  by  such  material  as  is  found  in 
Florida  and  the  West  Indies,  while  the  var.  minor  is  best  typified  by  specimens  of 
the  Orient.  In  the  Canary  Islands  and  a  few  other  places  these  two  varieties  tend 
to  approach  each  other  or  to  intergrade.  In  Mexico  and  the  West  Indies  var. 
radiata  tends  at  times  to  approach  var.  bimucronafa.

Linnaeus,  in  giving  the  habitat  of  his  Coreopsis  leucanthema, 
said,  "Hab.  in  Amer.  Miller."  In  the  Coreopsis  cover  in  the  Linnean 
Herbarium  is  still  to  be  found  Linnaeus'  specimen.  It  is  somewhat 
immature  but  has  one  head  with  whitish  rays.  These  are  less  well 
developed  than  those  usually  found,  but  much  more  conspicuous 
than  those  on  the  radiate  or  subradiate  var.  minor.  The  sheet  is 
labeled  "Leucanthema  radio  albo."  The  spelling  "leucanthema" 
is  seen  to  agree  with  that  found  originally  in  the  Amoenitates  Acade- 
micae  and  not  that  later  published  (leucantha)  in  the  second  edition 
of  the  Species  Plantarum.  Linnaeus  cited  two  synonyms,  the  first 
(Bidens  americana  trifolia,  leucanthemi  flore.  Tournefort.  inst. 
462)  being  apparently  that  from  which  he  derived  the  name  leucan- 
thema. In  his  Systema  Naturae  ed.  10.  2:  1228,  published  in  1759, 
he  again  used  the  name  leucanthema.  Although  the  name  leucantha 
was  adopted  later  by  Willdenow  (loc.  cit.)  and  has  been  accepted 
widely  since  then,  the  original  spelling  leucanthema  was  restored  by 
Krause  (loc.  cit.). 

When  we  trace  the  above  Linnean  citation  of  Tournefort's 
Institutiones,  we  find  that  Tournefort  gave  merely  two  lines  for 
the  plant  later  cited  by  Linnaeus:  "Bidens  trifolia,  Americana, 
Leucanthemi  flore.  Chrysanthemum  Americanum,  Ciceris  folio 
glabro,  Bellidis  majoris  flore  Prodr.  Par.  Bat."  Thus  it  is  seen  that 
Linnaeus'  first  cited  synonym  goes  back  directly  to  the  plant  listed 
in  Hermann's  Paradisi  Batavi  Prodromus.  However,  this  cited  plant 
is  the  same  as  that  listed  in  the  somewhat  later  (posthumous) 
Paradisus  Batavus  (edited  by  William  Sherard),  which  was  cited  by 
Linnaeus  for  his  Coreopsis  alba.1 

1  Linnaeus'  description  of  C.  alba,  the  second  citation,  and  the  habitat  all  refer 
to  Herm.  Par.  Bat.  124,  pi.  1%^,  His  first  citation,  however,  is  to  an  entirely 
different  plant  (Coreopsis  scandens,  foliis  serratis  ternato-pinnatis,  receptaculo 


438  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

On  studying  the  original  Coreopsis  leucanthema  description  and 
habitat  data  ("Caulis  trium  vel  quatuor  pedum,  ....  Foliolis 
quinque,  rarius  tribus,  ovatis  ....  Habitat  in  America.  Miller 
..."  Amoen.  Acad.  4:  291.  1759),  we  see  that  Linnaeus  did  not 
really  have  in  mind  the  plant  of  Hermann's,  but  rather  a  plant  re- 
ceived from  Philip  Miller  and  perhaps  the  same  specimen  that  is 
left  to-day  in  the  Linnean  Herbarium.1  Later,  Linnaeus  very  clearly 
showed  his  belief  that  the  two  plants  were  different  specifically, 
naming  the  Hermann  plant  Coreopsis  alba.  DeCandolle  (loc.  cit.) 
accepted  this  treatment,  transferring  Coreopsis  alba  to  Bidens  to 
accord  with  the  position  of  Bidens  leucantha  (L.)  Willd.  A  few 
years  ago  I  dealt  with  these  last  two  names  (Bot.  Gaz.  64:  32.  1917), 
stating  that  it  "seems  much  the  safer  course  to  retain  the  two 
names  separately  for  the  present  rather  than  merge  them  as  done  by 
O.  E.  Schulz."  Since  that  time  I  have  examined  several  hundreds  of 
additional  specimens  and  recently  have  concluded  that  B.  leucantha 
and  B.  alba  are  related  to  each  other  as  variety  and  forma  (becoming 
respectively,  as  will  be  seen  in  the  following  text,  var.  radiata  and 
var.  radiata  f.  Dondiaefolia)  .2 

Willdenow  compared  his  B.  leucantha  with  B.  biternata  (Lour.) 
Merr.  &  Sherff,  B.  pilosa  L.,  and  B.  pilosa  var.  minor  (Bl.)  Sherff  for 
several  years  under  cultivation  and  decided  it  to  be  distinct:  "Jam 
per  plures  annos  cum  binis  sequentibus3  culta  faciem  servavit" 
(Sp.  PI.  3:  1719.  1804).  Since  Willdenow's  time  its  status  has  been 
the  subject  of.  much  difference  of  opinion.  Asa  Gray,  who  gave 
considerable  attention  to  this  matter,  wrote  (Proc.  Amer.  Acad. 

nudo.  Brown,  jam.  321)  and  must  be  excluded,  as  it  conflicts  with  the  Linnean 
description  (cf.  DC.  Prodr.  5:  605.  1836. — "Syn.  Brownei  a  Linnaeo  citatum 
videtur  alienum  ex  recept.  nudo  dicto").  The  Browne  plant,  if  a  Bidens,  was  one 
of  the  tall,  yellow-flowered  climbers  found  in  Jamaica,  not  the  lower,  white- 
flowered  species  that  Linnaeus  had  in  mind. 

1  The  fact  that  the  sheet  bears,  as  already  stated,  the  original  spelling  "leucan- 
tiiema"  rather  than  the  later  spelling  "leucantha"  may  be  taken  as  evidence  that 
the  plant  is  the  original  Miller  specimen. 

2  In  a  former  article  (Bot.  Gaz.  64:  32.  1917),  I  stated  the  reasons  for  believing 
that  Bidens  Dondiaefolia  Less,  was  synonymous  with  Coreopsis  alba  L.     Subse- 
quently I  have  found  Lessing's  type   (Hlle.).     It  matches  exactly  (cf.  Sherff, 
Bot.  Gaz.  81:  44.  1926)  the  Milller  specimen  (No.  148;  N.Y.)  formerly  cited  by  me, 
thus  confirming  the  earlier  treatment.    For  detailed  presentation,  see  under  var.  7. 
radiata  f.  2.  Dondiaefolia. 

3  Viz.,  B.  biternata  (B.  chinensis)  and  B.  pilosa.    But  Willdenow's  herbarium 
material  of  B.  biternata  (Willd.  No.  15023)  consists  of  4  sheets,  nos.  1,  2,  3,  and  4. 
Nos.  1-3  are  B.  pilosa  L.  var.  minor  and  only  No.  4  bears  true  B.  biternata  (cf. 
O.  E.  Schulz,  in  Urb.  Symb.  Antill.  7:  135.  1911;  cf.  G.  Walpers— Nov.  Act.  Nat. 
Cur.  19,  Suppl.  1:  271.  1843 — who  erroneously  interpreted  Willdenow's  herb.  No. 
15023  as  being  identical  with  his — i.e.,  Willdenow's — herb.  No.  15022,  B.  pilosa 
var.  radiata,  i.e.,  B.  leucantha  Willd.).

19:  16.  1884):  "B.  leucantha  Willd.  This,  the  Coreopsis  leucanthema 
L.  Amoen.  Acad.,  C.  leucantha  L.  Sp.  ed.  2,-1282  (Desc.  Fl.  Ant. 
t.  583),  and  the  C.  coronata  L.  as  to  Plumier's  plant,  I  take  to  be 
quite  distinct  from  the  radiate  form  of  B.  pilosa."  But  0.  E.  Schulz, 
whose  writings  display  a  profound  and  comprehensive  knowledge  of 
a  number  of  the  species  of  Bidens,  treats  B.  alba,  by  which  he  means 
B.  leucantha  Willd.,  as  merely  a  variety  of  B.  pilosa  ("Einige  Autoren 
wollen  auch  jetzt  noch  die  Abart  als  selbstandige  Art  betrachten. 
Dieser  Ansicht  kann  ich  aber  nicht  beipflichten,  weil  ich  oft  direkte 
Ubergangsformen  gesehen  habe." — Bot.  Jahrb.  50,  Suppl.  176.  1914). 
In  1913,  Dr.  N.  L.  Britton,  who  had  had  considerable  field 
experience  with  these  forms,  told  me  that  B.  leucantha  and  B.  pilosa 
seemed  to  him  unquestionably  distinct  species,  not  only  in  leaf  and 
ray  but  in  the  appression  of  the  involucral  bracts  at  anthesis.  In 
1916,  however,  he  stated  to  me  that  as  a  result  of  further  field 
observations  he  had  decided  to  equate  the  two  in  one  species.  Not- 
withstanding the  opinion  held  by  Schulz,  Britton,  and  many  others, 
I  have  until  recently  maintained  the  two  as  separate  species.  A 
study  of  the  large  assemblage  of  specimens  in  Berlin  has  revealed, 
however,  several  "direkte  Ubergangsformen"  that  efface  quite 
effectually  the  specific  limits  and  compel  the  adoption  of  a  varietal 
rank  for  the  radiate  form.  Schultz  Bipontinus'  name  B.  pilosa  var. 
radiata  is  apparently  the  earliest  pertaining  to  varietal  rank. 

B.  striata  Sweet  (loc.  cit.;  etiam  Curtis'  Bot.  Mag.  59:  pi.  3155. 
1832)  is  a  form  with  large,  particularly  roseate  rays.1 

The  pre-Linnean  Bidens  trifolia  Feuill.  (not  listed  above)  is  cited 
by  some  authors  (e.g.,  Gay,  Hist.  Chil.  4:  293.  1849;  Reiche,  Fl. 
Chil.  4: 103. 1905)  as  a  synonym  for  B.  pilosa  var  alausensis  (H.B.K.) 
Sherff.  The  leaves  in  Feuilles'  illustration  (Journ.  Observ.  3:  10, 
pi.  4.  1725),  however,  match  better  those  of  B.  pilosa  var.  radiata.- 

Under  the  name  B.  leucantha  the  Materia  Medica  Mexicana  (2: 
153-172. 1898)  gives  a  comprehensive  treatment  from  the  standpoints 
of  history,  medicine,  botany,  etc.  The  treatment  there  doubtless 
applies  to  the  vars.  radiata  and  bimucronata,  each  in  part.

(Turcz.)  O.  E.  Schulz.

ber  6,  1922  (Field). 

In  his  Flora  of  The  British  West  Indian  Islands  (p.  373.  1861), 
Grisebach  stated  that  "a  remarkable  form,  with  all  the  leaves  simple, 
hispidulous  achenia,  and  whitish-pubescent  involucres,  was  collected 
by  Dr.  Alexander,  but  transitions  into  the  common  B.  leucanthus 
[i.e.,  B.  pilosa  var.  radiata  Schz.  Bip.]  occur  among  Mr.  March's 
specimens."  A  former  study  of  Alexander's  materials  left  me 
unconvinced  as  to  the  value  of  their  simple-leaved  character  for 
drawing  taxonomic  distinctions.  The  recently  collected  specimens 
by  De  La  Cruz  were  obtained  at  different  localities  and  about  two 
months  apart,  yet  both  reveal  in  all  respects  a  striking  similarity. 
The  leaves  all  are  simple,  thin,  glabrous,  the  blades  ovate-lanceolate, 
serrate,  acute  or  subacuminate  at  apex,  the  larger  ones  about  3.5-4 
cm.  long  and  1.5-2  cm.  wide,  the  petioles  slender  and  1-2  cm.  long. 
Compared  with  chance,  more  or  less  simple-leaved  plants  of  B. 
pilosa  proper  that  are  sometimes  found  (B.  pilosa  discodea  Schz.  Bip. 
em.  1.  subsimplicifolia  0.  Ktze.  Rev.  Gen.  1:  322.  1891;  "folia  omnia 
vel  plurima  integra  (cfr.  Gris.  Fl.  Westindien)" — Ktze.  loc.  cit.), 
also  of  B.  pilosa  var.  radiata  proper  (B.  pilosa  var.  leucantha  f.  sub- 
simplicifolia 0.  Ktze.  Rev.  Gen.  1:  322.  1891),  these  plants  appear  to 
represent  a  more  pronounced  and  less  ephemeral  form.

For  many  years,  Persoon's  variety  odoratissima  of  Coreopsis 
Ferulae/olio,  seems  to  have  been  unfamiliar  to  botanists.  DeCandolle 
(loc.  cit.)  merely  mentioned  it:  "quid  sit  var.  odoratissima  a  Per- 
soonio  citata  ignore."  Persoon's  variety  was  founded  on  Cavanilles' 
plant  in  Jussieu's  herbarium  and  was  said  to  be  native  to  Peru.  This 
cited  specimen  I  have  not  found,  but  there  exists  in  the  British 
Museum  of  Natural  History  a  good  specimen  from  Cavanilles, 
labeled  "Coreopsis  odoratissima  nobis,  Mexico,"  which  matches 
Persoon's  description  precisely.  The  leaves,  probably  because  of 
having  grown  under  cultivation,  are  especially  slender-divided  and 
give  a  superficial  resemblance  to  those  of  Bidens  Ferulaefolia  (Jacq.) 
DC.  The  specimen  is  identical  with  two  other  specimens  (Brit.) 
from  the  herbarium  of  Cavanilles,  one  labeled  "Coreopsis  odorata 
olim  Bidens,"  and  the  other  "Bidens  odorata  Cav.  Ic.  V.  1.,  nunc 
Coreopsis."  Both  of  these  last  two  are  further  labeled,  in  pencil, 
"Cosmos  odoratus"  Clearly,  Persoon's  variety  is  perfectly  synony- 
mous with  Bidens  odorata  Cav. 

Coreopsis  multifida  DC.  and  its  var.  mutica  DC.  are  represented 
by  the  type  specimens  in  the  herbarium  of  DeCandolle's  Prodromus 
(Del.).  The  species  was  collected  (fide  DC.  loc.  cit.),  by  Pa  von, 
possibly  in  Peru;  the  variety  was  from  seed  previously  sent  by  Dom- 
bey  from  "Peruvia"  to  the  Botanical  Garden  at  Paris.  Both  are 
found  on  careful  comparisons  to  be  merely  Bidens  odorata  Cav.1 

1  The  citation  of  Peru  would  seem  to  indicate  that  the  material  is  really  best 
considered  as  the  rather  similar  var.  alausensis  f.  Scandicina,  the  form  native  to 
South  America.  The  plants  are  more  like  the  North  American  material  of  f. 
odorata.  Whether  a  mistake  was  made  originally  in  the  mention  of  Pavon  and 
Peru  for  these  plants  I  can  not  say  for  certainty,  although  the  indications  point 
that  way.  We  may  note  the  partly  comparable  case  of  Bidens  Sambucifolia  Cav., 
said  to  have  come  from  Peru  and  Mexico,  but  which  has  never  been  known  from 
outside  of  Mexico.  The  evidence  in  herbaria  indicates  that  Cavanilles  got  his 
material  in  this  case  from  or  rather  through  Pavon,  and  thus  Pavon's  written  data 
were  at  fault.  Regarding  another,  somewhat  different  case  of  mislabeling  observed 
in  much  of  the  "Pavon"  material  cf.  Hemsley,  Biol.  Centr.  Amer.  Bot.  4:  120. 
1887  ("as  Pavon  himself  was  never  in  Mexico,  and  there  is  evidence  of  his  having 
dealt  freely  in  the  sale  of  dried  plants").

Bidens  Caucalidea  DC.  was  described  from  Berlandier  1138.  The 
sheet  of  this  number  in  the  Museum  of  Vienna  has  one  specimen 
with  bipinnate  leaves,  approaching  Bidens  odorata  Cav.  and  another 
with  some  of  the  principal  leaves  only  tripartite,  approaching  B. 
pilosa  var.  bimucronata.  At  Washington  (U.S.)  are  two  sheets  of  the 
fine  material  collected  by  Arsene.  It  is  remarkably  close  to  the  type 
material  of  B.  Caucalidea  and  might  well  serve  as  a  supplementary 
type  for  the  concept  represented  by  that  name.  Four  of  the  five 
specimens  there  have  the  leaves  mainly  bipinnate  as  in  B.  odorata 
Cav.  but  the  remaining  specimen  has  the  leaves  tripartite  as  in  the 
var.  bimucronata.1  Obviously  the  amount  of  foliar  division  is  of 
little  value  here  in  determining  specific  limits.  Likewise  a  study  of 
various  other  specimens  (referred  to  B.  odorata  Cav.  or  to  B.  Cau~ 
calidea  DC.  by  different  botanists),  with  reference  to  achenial  shape, 
size,  and  armature,  to  width  of  flowering  heads,  and  to  general 
branching  habit,  reveals  an  astonishing  amount  of  variation.  A 
form  with  the  upper  part  of  the  main  stem  broken  away  and  the 
lower  part  profusely  branched  is  the  plant  formerly  described  as 
Bidens  Deamii  Sherff.  B.  ramosissima  Sherff  is  probably  best  inter- 
preted as  merely  a  mutant  form  with  an  excessive  degree  of  branch- 
ing and  the  involucres  finally  becoming  reflexed  to  a  notably  uniform 
extent.  A  specimen  collected  by  Seemann  (Kew)  is  positively  the 
B.  odorata  of  Cavanilles  and  yet  in  its  highly  branched  character 
displays  an  approach  to  the  type  specimen  of  B.  ramosissima. 

Certain  specimens  of  Berlandier  1138  were  rather  under-de- 
veloped in  stature,  somewhat  pubescent-hirtellous,  and  had  the  leaf 
segments  more  acute.  These  DeCandolle  assumed  to  be  another 
species,  confused  with  the  B.  Caucalidea  material  by  Berlandier  in 
the  gathering.  He  named  them  B.  Daucifolia.  For  B.  Daucifolia, 
as  for  his  B.  Caucalidea,  he  described  the  rays  as  yellow.  Since 
DeCandolle's  day,  many  (yellow-rayed)  Mexican  specimens  of  B. 
triplinervia  var.  macrantha  (Wedd.)  Sherff  have  been  determined  by 
students  (myself  among  them)  as  B.  Daucifolia  DC.,  but  recent 
study  of  the  long  neglected  type  material  of  B.  Daucifolia  at  Geneva 
(Del.)  and  Paris  (Par.)  showed  that  B.  Daucifolia  is  not  a  yellow- 
rayed  form.  The  Geneva  sheet  has  a  single  small  specimen,  with 
one  flowering  and  one  fruiting  head.  The  ligules  are  a  faded  rosaceous 
color,  not  yellow  as  DeCandolle  had  stated.  The  achenes  are  those 
of  B.  odorata  Cav.  The  Paris  sheet  has  three  small  but  good  speci-

mens.  Three  radiate  heads  are  present,  of  a  faded  rosaceous  color. 
One  specimen  has  a  head  of  biaristate  achenes  and  another  has  two 
ample  fruiting  heads  of  exaristate  achenes.  These  specimens  all 
are  mere  variations  of  B.  Caucalidea  DC.,  and  there  is  no  reason  to 
suppose  that  Berlandier  confused  two  sorts  with  each  other.  Clearly 
B.  Daucifolia  DC.  and  B.  Caucalidea  DC.  are  synonymous,  and 
together  must  be  equated  in  turn  with  the  earlier  B.  odorata  Cav. 

Judged  by  standards  maintained  in  many  other  genera,  there 
would  seem  to  be  no  less  than  eight  or  ten  varieties  and  racial  formae 
represented.  To  encumber  taxonomy  with  a  large  number  of  addi- 
tional names,  when  the  variations  are  so  capricious  and  fickle  as 
often  to  result  in  two  or  three  unlike  fades  upon  a  single  herbarium 
sheet,1  would  appear  entirely  unwarranted.  Therefore,  these  vary- 
ing forms,  all  of  them  intimately  related  to  B.  pilosa  var.  bimucronata 
but  tending  to  display  more  or  less  bipinnate  leaves  on  most  of  the 
individual  plants,  are  grouped  as  the  forma  odorata  of  that  variety. 
Complicated  and  undesirable  as  the  name  resulting  from  this  inter- 
pretation will  be,2  it  is  the  only  one  that  appears  to  accord  with  the 
facts  in  nature. 

The  type  of  Cosmos  tenellus  H.B.K.  (or  Bidens  Bonplandii  as  it 
was  later  renamed  by  Schultz  Bipontinus  upon  its  transfer  to  Bidens) 
was  collected  between  the  City  of  Mexico  and  Huahuatoca  (variously 
spelled  Huehuetoca,  Giiegiietoque,  etc.)  in  the  State  of  Mexico, 
Mexico.  A  search  in  1914  and  again  in  1924  among  the  type  sheets 
of  the  Humboldt,  Bonpland,  and  Kunth  set  at  Paris  failed  to  reveal  a 
specimen  with  the  name  Cosmos  tenellus,  nor  was  there  authentic 
material  at  Berlin.  The  description  by  Kunth  shows  that  the  type 
was  without  achenes.  The  bipinnatipartite  foliage  and  the  probably 
rosaceous  color  of  the  ligules  evidently  had  led  him  to  place  the  plant 
in  Cosmos.  A  survey  of  Cosmos  and  Bidens  at  the  present  time  indi- 
cates that  Kunth's  extended  description  fits  none  other  than  the 
present  f .  odorata  of  Bidens  pilosa  var.  bimucronata.  This  forma,  as 
well  as  its  supravening  variety  bimucronata,  is  very  abundant 

1  C.  V.  Hartman  564  (Gray)  and  C.  A.  Purpus  1544  (Calif.)  are  especially  good 
examples  of  this. 

2  O.  Kuntze  (Rev.  Gen.  1:  322.  1891)  put  forth  a  treatment  of  Bidens  pilosa 
in  which  he  adopted  the  even  more  complicated  and  unwelcome  method  of  pro- 
posing varieties,  subvarieties,  and  forms  (formae).    His  name  subbiternata  is  seen, 
on  carefully  reading  the  related  names,  to  have  been  used  for  a  subvariety  or  group 
(under  B.  pilosa)  ranking  lower  than  a  variety  but  higher  than  a  forma  (thus  cf. 
B.  pilosa  a.  leucantha  2.  ternata  f.  pilosior,  loc.  cit.).    Yet,  even  were  the  formal  rank 
of  the  name  subbiternata  accepted,  it  could  not  conflict  with  the  validity  of  the  claim 
of  odorata  to  formal  rank,  as  subbiternata  pertained  to  a  form  of  B.  pilosa  var. 
radiata,  not  of  var.  bimucronata.

throughout  the  region  surrounding  the  type  locality  of  Cosmos 
tenellus.  Moreover,  the  general  aspect  is  often  deceptively  like  that 
of  Cosmos,  a  fact  easily  explaining  Kunth's  reference  of  his  type 
to  that  genus.1 

The  type  of  Bidens  inermis  Wats,  is  matched  by  Pringle  1638, 
5999,  and  7904.  All  four  numbers  have  achenes  especially  slender 
and  long-attenuate,  as  well  as  exaristate.  The  forma  odorata  is 
known  frequently  to  produce  achenes  wholly  or  in  part  of  this  very 
kind,  thus  leaving  no  grounds  for  the  retention  of  B.  inermis  as  a 
species.2  It  may  be  remarked  that  0.  E.  Schulz,  in  1911,  studied 
some  of  the  B.  inermis  material  (e.g.,  Pringle  1638)  in  the  Berlin 
Herbarium  and  labeled  it  B.  Caucalidea  DC.,  which  in  turn,  as  al- 
ready stated,  is  merely  another  synonym  for  f.  odorata. 

The  grayish  green  or  bluish  green  color  of  the  herbage  in  the 
forma  odorata  often  is  very  noticeable.  The  Mexicans  appear  to 
prefer  this  form  and  also  the  var.  bimucronata  proper  for  food.  Under 
the  name  of  "aceitillo"  (fide  A.  Dugesii  471,  Gray;  Wm.  E.  Saffordii 
1391,  U.S.;  et  al.),  the  young  plants  are  boiled  and  eaten  with  pinole 
and  salt  (fide  C.  V.  Hartmanii  564,  Gray).

states  of  Puebla  and  Michoacan  (U.S.)  had  been  distributed  by  Arsene  under  the 
name  Cosmos  tenellus  H.B.K.  and  that  these  are  our  f.  odorata. 

2  The  singular  aspect  of  the  fruiting  heads  upon  typical  "B.  inermis"  might 
be  taken  as  justifying  a  subformal  rank  under  f.  odorata,  but  the  already  lengthy 
name  B.  pilosa  var.  bimucronata  f.  odorata  would  seem  to  suggest  restraint  in  this 
matter.    Furthermore,  some  material  (e.g.,  Edward  Palmer  673,  Kew)  has  fruiting 
capitula  precisely  like  those  in  the  type  collection  of  B.  inermis  but  merely  3-5- 
partite  leaves  as  in  B.  pilosa  var.  bimucronata  proper,  thus  displaying  an  overlap- 
ping of  characters.

The  Willdenow  Herbarium  has  a  sheet  of  Bidens  diversifolia 
Willd.  (ex  DC.)  and  this  sheet  bears  two  plants.  One  is  referable  to 
var.  alausensis,  but  the  other  seems  more  like  B.  andicola  H.B.K. 
Willdenow  doubtless  construed  them  to  be  genetically  the  same, 
hence  his  name  diversifolia.  It  appears,  however,  that  this  was 
merely  a  case  of  mixed  material.  Fortunately,  the  very  definite 
status  and  validity  of  the  names  alausensis  and  andicola  permit  us 
to  ignore  the  name  B.  diversifolia  Willd. 

In  a  former  article  (Bot.  Gaz.  59:  310-311,  fig.  1.  1915)  I  have 
discussed  the  identity  of  B.  valparadisiaca  Colla  and  B.  chilensis 
DC.  with  B.  alausensis  H.B.K.,  and  presented  photographs  of 
Kunth's  type  of  B.  alausensis  H.B.K.  In  1924  I  made  a  careful 
reexamination  of  Kunth's  type  and  of  four  sheets  of  cotype  material 
(Par.;  Berl.)  and  came  to  the  same  conclusion  as  before.  A  study  of 
various  other  specimens  shows  that  B.  alausensis  H.B.K.  cannot 
properly  be  regarded  as  specifically  distinct  from  B.  pilosa  L.  Thus, 
for  example,  J.  F.  Macbride  2899  and  2901,  at  altitude  of  about 
2,400  meters,  Matucana,  Peru,  etc.  (Field),1  have  tripartite  leaves 

1  These  and  the  other  Macbride  specimens  cited  were  obtained  by  Mr.  Mac- 
bride,  who  had  the  matter  particularly  in  mind  on  his  recent  South  American 
expedition.  Of  each  number  I  have  seen  various  duplicates  awaiting  distribution  to 
other  herbaria.

2902  (Field),  collected  at  the  same  place  and  same  time  as  Macbride

close  to  or  identical  with  various  specimens  of  B.  alausensis  H.B.K. 
from  Chile  and  Ecuador.2  Macbride  2900  p.p.,  altitude  about  2,400 
meters,  Matucana,  Peru,  March  14-18,  1923  (Field),  and  3473, 
altitude  about  2,550  meters,  Cani,  Peru,  April  16-26,  1923,  also  are 
identical  in  habit  and  technical  characters  with  B.  alausensis,  except 
that  they  are  taller  and  more  robust  and  their  foliage  is  more  finely 
cut,  becoming  even  tripinnatisect.  These  are  identical  with  A. 
D'Orbigny  1234,  Bolivia  (Par.),  labeled  Bidens  Scandicina  var. 
glabrescens  by  Weddell.  They  match  also  the  Berlin  and  Paris 
cotypes  of  B.  Scandicina  H.B.K.,  except  that  the  latter  have  more 
pubescent  leaves  with  somewhat  finer  divisions.  It  is  significant 
that  the  types  of  B.  alausensis  H.B.K.  and  B.  Scandicina  H.B.K., 
here  seen  to  be  so  closely  connected  by  intermediate  specimens, 
were  collected  by  Humboldt  and  Bonpland  in  the  same  vicinity: 
B.  alausensis  between  Alausi  and  Tambo  de  Guamote  (the  type 
label  gives  merely  "Alausi"),  Ecuador,  and  B.  Scandicina  between 
Llactacunga  and  Ambato,  Ecuador. 

It  might  seem  at  first  that  there  is  here  a  situation  comparable 
with  that  in  B.  pilosa  var.  bimucronata  (Turcz.)  0.  E.  Schulz,  where 
the  form  with  finely  divided  leaves  is  reducible  to  subordinate  rank 
as  f.  odorata  (Cav.)  Sherff.  In  such  a  case  we  should  have  the  names 
alausensis  and  Scandicina  taking  respectively  formal  and  subformal 
rank  under  the  name  B.  pilosa  var.  radiata,  giving  names  which 
would  be  very  cumbersome.  It  seems  more  probable  that  in  the 
present  case  the  alausensis  and  Scandicina  forms  do  not  intergrade 
nearly  so  much  with  B.  pilosa  var.  radiata  as  does  the  odorata  form 
with  B.  pilosa  var.  bimucronata.  Hence  there  appears  good  reason 
for  assigning  B.  alausensis  varietal  status  directly  under  B.  pilosa, 
and  reducing  B.  Scandicina  to  a  forma  under  the  variety.

1  In  the  Buchtien  specimens  the  similarity  to  certain  Umbelliferae,  implied  in 
the  name  Scandicina,  is  most  striking.  In  fact,  before  seeing  the  Sodiro  (cf. 
Hieronymus,  Bot.  Jahrb.  29:  48.  1901)  and  de  Jelski  specimens,  I  had  not  thought 
to  connect  the  Buchtien  specimens  with  f.  Scandicina,  and  had  tentatively  con- 
sidered them  as  representing  a  new  species.  Curiously  enough,  I  too  had  been 
impressed  with  the  resemblance  to  certain  Umbelliferae,  especially  Musineon, 
and,  to  a  lesser  extent,  Chaerophyllum,  and  had  tentatively  employed  a  trivial 
name  based  upon  the  resemblance  to  Musineon.  In  one  specimen  by  Buchtien 
(No.  811)  the  foliage  and  general  habit  suggest  also  those  of  Anthemis  Cotula  L.

THE  GENUS  BIDENS  455 

Type  specimen:  Collected  by  Eduard  Poeppig,  No.  207,  in  rocky 
and  gravelly  maritime  places  near  Valparaiso,  Chile,  June  (Del.)- 

Distribution :  Known  only  from  Chile. 

Specimens  examined:  Erik  Asplund  42,  Valparaiso,  July  17, 
1921  (Stockh.);  Poeppig  207  (type,  Del.:  cotypes,  Berl.;  Hll.;  Kiel; 
Mus.  V.,  etc.). 

In  a  former  article  (Bot.  Gaz.  76:  158.  1923),  Bidens  chilensis 
var.  Apiifolia  DC.  was  discussed  and  the  Berlin  cotype  (Poeppig 
207)  of  that  variety  was  treated  as  "an  unimportant  foliage  form  of 
B.  alausensis."  Subsequent  study  of  much  cotype  material,  in 
conjunction  with  several  specimens  collected  by  J.  F.  Macbride  at 
Matucana,  Peru,  revealed  closer  affinities  of  several  of  the  original 
specimens  with  B.  pilosa  var.  radiata  Schz.  Bip.  Specimens  of  Poep- 
pig 207  were  studied  in  collections  belonging  to  several  of  the  older 
herbaria.  Two  specimens  in  Vienna  and  one  in  Berlin  appeared 
closer  to  var.  alausensis,  but  the  cotypes  elsewhere  appeared,  when 
studied  in  the  light  of  the  interesting  Macbride  specimens  previously 
described  (cf.  Bot.  Gaz.  81:  35.  1926),  to  be  closer  to  var.  radiata. 

The  nomenclatural  problem  offered  by  the  publication  in  1836 
by  DeCandolle  of  this  var.  Apiifolia  is  particularly  vexing,  since  its 
publication  antedated  that  for  both  the  var.  alausensis  and  the  var. 
radiata.  An  equation  of  the  var.  Apiifolia  with  either  of  these  two 
varieties  would  compel  the  taking  up  of  the  name  Apiifolia  and  the 
reduction  of  a  well  established  name  to  synonymy.  The  intermediate 
nature  and  ill  denned  status  of  the  var.  Apiifolia  would  make  such 
a  course  seem  unwise,  if  not  indeed  impossible.  Apparently  the 
interests  of  taxonomy  are  best  conserved  by  employing  the  com- 
bination B.  pilosa  var.  Apiifolia  to  apply  only  to  the  form  inter- 
mediate between  vars.  alausensis  and  radiata,  and  represented  by 
Poeppig  207.  In  this  case,  the  last  two  names,  each  certain  in  its 
application  and  well  supported  in  herbaria  by  illustrative  material, 
are  left  undisturbed.1

1  Concerning  the  intermediate  nature  of  var.  Apiifolia,  it  may  be  remarked 
that  while  DeCandolle  ranked  this  variety  under  B.  chilensis  DC.  (=B.  pilosa  var. 
alausensis),  Poeppig's  original  printed  labels  bore  the  name  "B.  leucantha  L." 
(-B.  pilosa  var.  radiata).

aristate,  upwardly  attenuate  achenes,  appear  widely  different  from 


458  FIELD  MUSEUM  OF  NATURAL  HISTORY— BOTANY,  VOL.  XVI 

typical  B.  pilosa  L.  A  study  of  the  other  herbarium  specimens 
cited  above,  however,  shows  it  to  be  impossible  to  maintain  separate 
specific  rank  for  them;  rather  must  they  be  given  varietal  rank 
under  B.  pilosa  as  was  done  by  0.  E.  Schulz  (loc.  cit.).  According 
to  the  International  Rules,  the  earlier  varietal  name  calcicola  must 
be  applied  here.1  The  type  of  the  var.  calcicola,  Pringle  11340 
(Gray),  has  a  single  pair  of  stem  leaves  present,  these  pinnately 
5-parted,  with  the  terminal  and  basal  leaflets  more  or  less  definitely 
3-parted;  the  divisions  are  lanceolate;  the  involucres  are  rather 
densely  canous-pubescent.  These  characters  are  found  to  be  dupli- 
cated in  various  of  the  specimens  above. 

DeCandolle  appears  to  have  attached  undue  importance  to  the 
amount  of  scabridity  on  the  achenial  surfaces.  Thus  he  placed 
Berlandier  5  and  113,  with  achenes  scabrous,  in  his  new  species  B. 
brachycarpa,  but  Berlandier  2220,  with  achenes  less  glabrous2  and 
happening  to  have  a  taller,  more  corymbose  habit,  with  the  terminal 
leaflets  more  elongate,  he  described  separately  under  the  new  name 
B.  exaristata.  The  technical  characters  of  flowers  and  fruit  offer 
no  warrant  for  maintaining  B.  exaristata  as  a  separate  species  or 
variety  apart  from  the  var.  caleicola.  As  to  the  somewhat  taller 
habit  and  more  corymbosely  or  even  fastigiately  branched  inflores- 
cence observed  in  certain  specimens  (Berlandier  39,  Del.,  Par.; 
idem  2220,  Del.,  Par.;  Nelson  2111,  U.S.),  these  seem  to  be  merely 
the  result  of  a  capricious  growth.  Indeed,  Berlandier  800  and  2220 
in  the  Gray  Herbarium  have  a  much  more  loosely  corymbose  in- 
florescence as,  in  fact,  DeCandolle's  description  states  ("laxe  corym- 
bosa"),  and  thus  at  once  remove  from  consideration  the  only  charac- 
ter that  by  some  botanists  might  be  thought  important.  Through 
the  first  Berlandier  specimen  just  cited  (No.  800)  an  approach  is 
made  to  B.  pilosa  var.  bimucronata  (Turcz.)  0.  E.  Schulz,  a  variety 

1  The  Berlin  Herbarium  has  several  specimens  of  B.  pilosa  (leg.  Sello  et  al.) 
with  mature  achenes  only  4-5  mm.  long  and  closely  simulating  the  var.  calcicola 
plants  in  all  important  respects  except  that  they  lack  rays.     Similarly,  various 
herbaria  have  plants  of  the  var.  radiata  with  diminutive,  commonly  pubescent 
leaves  and  many  of  the  fruiting  heads  minute,  approaching  the  var.  calcicola  type 
so  closely  as  practically  to  efface  all  varietal  distinctions.    The  Tonduz  specimens 
might  almost  equally  well  be  regarded  as  of  the  species  proper,  and  in  fact  had  been 
treated  as  that  by  me  until  the  same  local  form  appeared  again  during  further 
studies  (Cooper  5814),  with  some  of  the  heads  radiate. 

2  DeCandolle  (loc.  cit.)  actually  described  the  achenes  as  glabrous  ("achaeniis 
glabris"),  but  in  two  sheets  of  Berlandier  2220  (Del.),  many  of  the  achenes  are  dis- 
tinctly scabrous  near  the  apex. 

O.  E.  Schulz  (loc.  cit.),  evidently  relying  upon  DeCandolle,  likewise  regarded 
B.  exaristata  as  having  glabrous  achenes.  Thus  he  stated:  '  B.  exaristatus  DC. 
.  .  .  ab  hac  varietate  [B.  pilosa  var.  bimucronata]  acheniis  glabris  differt."

the  var.  bimucronata  and  its  form  with  more  compound  foliage  (i.e., 
f.  odorata},  there  are  found  at  times  stunted  or  dwarfed  specimens 
which  have  flowering  and  fruiting  heads  diminutive  enough  to  be 
taken  for  var.  calcicola  and  f.  dissecta.  It  is  therefore  possible  that 
in  some  of  my  past  herbarium  determinations  I  may  have  confused 
the  two  varieties  and  their  respective  forms  to  a  slight  extent.2

0.  E.  Schulz  (loc.  cit.)  found  in  the  herbarium  of  the  Botanical 
Garden  at  Berlin  three  sheets  of  Bidens  material  collected  by  Sello 
(the  name  often  spelled  "Sellow"  in  literature),  No.  607,  in  Brazil. 
These  he  determined  as  Bidens  megapotamica  Spreng.,  although 
the  labels  bore  no  data  as  to  the  locality  in  Brazil  whence  the  plants 
came.  Sprengel's  description  was  based  upon  a  plant  collected  by 
Sello  at  "Rio  Grande"  in  "Brazil."1  That  Schulz  had  not  seen  this 
Rio  Grande  specimen  is  shown  by  his  citing  it  "Sellow  ex  Sprengel." 
In  1923  (Bot.  Gaz.  76: 91)  I  presented  these  and  other  facts  and  stated 
the  conclusion  that  Bidens  megapotamica  was  a  species  of  Thele- 
sperma  and  as  such  had  been  correctly  renamed  Thelesperma  mega- 
potamicum  (Spreng.)  0.  Kuntze  (taking  precedence  in  Thelesperma 
over  the  synonym  T.  Scabiosoides  Less.). 

In  1926  (Bot.  Gaz.  81:  252-254)  I  reported  finding  what  seemed 
an  authentic  specimen  of  Bidens  megapotamica  Spreng.  in  the  Deles- 
sert  Herbarium  and  on  the  strength  of  that  specimen,  of  the  well 
known  Isostigma  Peucedanifolium  (Spreng.)  Less.,  made  the  new 
combination  I.  megapotamicum  (Spreng.).  About  the  same  time, 
but  too  late  to  prevent  publication  of  this  new  combination  (vide 
Bot.  Gaz.  83:  425.  1927),  Dr.  S.  F.  Blake  reported  finding  the  true 
type  of  B.  megapotamica  Spreng.  in  the  Schultz  Bipontinus  Herbarium 
(Par.).  This  plant,  as  his  photograph  and  observations  showed,  was 
true  Thelesperma  Scabiosoides  Less.  Thus  the  plant  of  the  Delessert 
Herbarium  was  seen  to  be  of  spurious  or  at  least  erroneous  determina- 
tion, and  my  first  reasoning,  namely,  that  Bidens  megapotamica 
Spreng.  was  equivalent  to  and  took  precedence  over  Thelesperma 
Scabiosoides  Less,  (thus  validating  the  name  Thelesperma  mega- 
potamicum [Spreng.]  0.  Ktze.),  was  proved  correct. 

1  Sprengel  Latinized  the  citation  Rio  Grande  to  read  "Ad  fl.  magnum  Amer. 
austr.,"  evidently  thinking  that  a  Rio  Grande  River  had  been  meant  by  Sello. 
The  name  megapotamica  would  seem  to  emphasize  this  fact.  A  study  of  various 
specimen  labels,  however,  shows  that  Sello  collected  many  specimens  either  in  the 
State  of  Rio  Grande  Do  Sul  or  in  the  country  just  south,  which,  although  shortly 
after  Sello's  collecting  separated  from  Brazil  under  the  name  of  Uruguay,  was 
considered  a  part  of  Brazil  when  Sello  collected,  and  may  easily  have  been  con- 
sidered by  him  a  part  of  the  adjacent  province  of  Rio  Grande  Do  Sul.  Thus  we 
read  (as  given  by  Lessing,  Linnaea  6:  103.  1831):  "Sellow  in  Brasilia  meridionali 
ad  Rio  Pardo  Octbr.  et  Novbr.  1823";  ibid.  141,  "In  Monte  Video  Commerson 
et  Sellow";  ibid.  516,  "Sellow  in  Campis  ad  Rio  Nigro."  In  this  connection  we 
may  note  also  that  DeCandolle  (Prodr.  5:  634.  1836)  cites  for  the  State  of  Rio 
Grande  Do  Sul  four  species  of  Thelesperma  and  Isostigma  collected  by  Sello  and 
cited  by  Lessing  merely  as  coming  from  Brazil. 


THE  GENUS  BIDENS  465 

This  is  particularly  reassuring,  since  it  enables  us  definitely  to 
eliminate  from  consideration  the  trivial  name  megapotamica  in  the 
genus  Bidens,  where  it  had  been  placed  erroneously  by  0.  E.  Schulz 
(loc.  cit.),  and  for  the  one  species  considered  here  to  take  up  the 
name  B.  subalternans  DC. 

Bidens  platensis  Mang.  was  described  as  a  hybrid  between  B.  pilosa 
L.  (staminate)  and  "B.  bipinnata  L."  (pistillate).  A  study  of  Miss 
Manganaro's  text  convinced  me  some  time  ago  that  the  plant  which 
had  been  assumed  to  be  B.  bipinnata  L.  was  in  reality  B.  subalternans 
var.  simulans.  Recently  I  was  given  valuable  aid  in  the  determi- 
nation of  B.  platensis  by  Professor  Angel  L.  Cabrera  of  the  La  Plata 
Museum  in  Argentina.  In  a  letter  he  wrote  to  the  following  effect: 
His  numerous  searches  in  the  past  for  the  type  of  B.  platensis  had 
been  fruitless.  He  therefore  had  given  the  type  up  for  lost. 
Recently,  however,  he  had  been  entrusted  with  the  rearrangement 
of  the  Spegazzini  collections  for  the  La  Plata  Museum.  Now,  the 
late  Miss  Manganaro  had  been  a  pupil  of  Spegazzini,  and  at  her 
death  her  parents  sent  her  collections  to  Spegazzini.  Professor 
Cabrera  found  her  collections  inside  an  old  chest,  in  November,  1930. 
The  herbarium  was  in  great  disorder,  without  labels  or  any  other 
indications.  There  were,  however,  several  specimens  of  Bidens  that 
had  been  very  carefully  mounted,  and  these  were  "closely  similar  to 
the  original  figure  of  B.  platensis."  Since  no  other  specimens  in  the 
Manganaro  collection  had  been  given  such  special  care,  Professor 
Cabrera  concluded  (without  doubt  rightly)  that  these  specially 
mounted  ones  represented  the  type  material  of  B.  platensis.  He 
lent  two  of  the  supposedly  type  specimens  for  study  and  they  are 
now  before  me.  Both  are  typical  B.  subalternans.

At  times  Bidens  subalternans  is  found  with  the  leaves  delicately 
2-3-pinnatisect  and  the  segments  linear,  even  narrowly  so.  For  a 
number  of  years,  when  making  herbarium  determinations,  I  included 
such  forms  under  the  species  proper  without  distinction.  Only  more 
recently  have  I  distinguished  them  as  var.  simulans.  In  some 
cases  they  suggest  B.  bipinnata  L.  so  strongly  as  to  create  confusion. 
In  other  cases  they  display  a  slight  approach  to  B.  exigua  Sherff. 

Bidens  subalternans  var.  7.  unipinnata  Sherff,

A  specie  foliis  pinnatim  3-5-partitis  foliolis  lanceolatis  vel  ovato- 
lanceolatis  differt. 

Type  specimen:  Collected  by  Emil  Hassler,  No.  11558,  in  the 
region  of  Lake  Ypacaray,  central  Paraguay,  February,  1913  (Gray). 

Distribution:  Argentina,  Paraguay,  and  Brazil. 

Specimens  examined:  Beyrich,  in  rubbish-strewn  places  near  Rio 
de  Janeiro,  Brazil  (Stockh.) ;  Blanchet  816,  about  Bahia,  Brazil,  1831 
(N.Y.);  R.  E.  Fries,  Santa  Barbara,  Prov.  Salta,  Argentina,  July, 
1901  (Stockh.);  Hassler  11558  (Gray,  type);  P.  Jorgensen  1080, 
Comau,  Andalgala,  Prov.  Catamarca,  Argentina,  November  11, 
1916  (Mo.);  idem  2041,  Terr.  Chaco,  Argentina  (Mo.);  G.  A.  Malme 
1410B,  in  rubbish-strewn  places,  Santa  Anna  da  Chapada,  Matto 
Grosso,  Brazil,  February  20,  1894  (Stockh.);  Martins,  herb-grown 
places  along  San  Francisco  River  near  Joazeiro,  Bahia,  Brazil, 
March-April  (Kew);  L.  R.  Parodi  7787,  adventive  in  cultiva- 
tions, Lanugasta,  Chilecito,  Prov.  La  Rioja,  Argentina,  January  31, 
1927  (Gray). 

Occasionally  a  South  American  specimen  of  Bidens  is  found  with 
the  general  aspect  of  B.  pilosa  L.,  but  with  the  fruiting  heads  as 
in  the  closely  related  B.  subalternans.  A  close  inspection  shows  that 
the  only  difference  from  typical  B.  subalternans  is  in  the  once-pinnate 
(instead  of  twice-pinnate)  leaves.

Distribution:  Widely  distributed  throughout  the  West  Indies;  in 
State  of  Yucatan,  Mexico,  and  throughout  northern  South  America 
to  central  Peru  and  the  states  of  Matto  Grosso  and  Ceara,  Brazil; 
has  been  collected  (T.  Thomson)  also  in  northwestern  Himalaya, 
British  East  India,  where  doubtless  adventive;  recently  established 
in  the  Hawaiian  Islands.

1  The  type  sheet  gives  Havana  for  the  locality,  but  Bonpland's  private  dupli- 
cate sheet  gives  "Guanayacoa"  (Guanabacoa;  across  the  small  bay  from  Havana) 
and  so  does  Kunth's  original  description. 

2  Many  of  these  specimens  were  listed  in  the  manuscript  before  it  was  decided 
to  maintain  any  varieties  of  B.  Cynapiifolia,  hence  possibly  a  very  few  are  included 
which  belong  to  var.  portoricensis  or  var.  tennis.

Brandegee's  original  description,  like  several  others  of  his  Bidens 
descriptions,  was  carelessly  drawn.  The  exterior  involucral  bracts 
are  linear,  not  "linear-lanceolate."  The  terminal  leaflet  is  larger, 
not  "much  smaller"  than  the  lateral  ones.  The  achenes  are  almost 
uniformly  shorter  than  he  says,  very  few  being  "20-25  mm."  long. 

0.  E.  Schulz  (loc.  cit.),  in  reducing  this  form  to  varietal  rank 
under  B.  riparia,  differentiated  the  two  forms  on  the  basis  of  fruit 
characters,  but  an  examination  of  many  specimens  of  each  form  shows 
that  the  only  genuine  difference  is  in  the  foliage.  B.  refracta  Bran- 
deg.  has  tripartite  leaves  while  B.  riparia  H.B.K.  has  bipinnate  or 
tripinnatisect  leaves.  This  difference  Schulz  seems  to  have  over- 
looked. Indeed,  he  even  refers  to  B.  refracta,  Tonduz  13618,  a  plant 
identical  in  foliage  and  other  parts  with  the  type  and  Bonpland  co- 
type  of  B.  riparia.1 

Several  years  ago,  on  having  examined  22  collections  of  the 
refracta  form  and  failed  to  find  more  than  one  approach  in  foliage  to 
that  of  B.  riparia,  I  concluded  (Bot.  Gaz.  64:  35.  1917)  that  "the 
probabilities  are  strong  that  B.  refracta  and  B.  riparia  are  entirely 
distinct  species."  Since  then,  I  have  seen  several  other  foliage 
intergradations.  Furthermore,  we  have  the  important  consideration 
that  in  numerous  species  of  Bidens  the  foliage  is  known  positively 
to  vary  from  tripartite  (or  even  simple)  to  bipinnate  or  tripinnatisect. 
Thus  all  attempts  to  defend  a  specific  segregation  of  the  tripartite- 

1  Schulz's  confusion  of  the  refracta  with  the  riparia  forms  is  shown  further  by 
certain  of  his  determinations  at  Berlin.  For  example,  he  there  referred  not  only 
Tonduz  13618,  but  also  Bernoulli  &  Carlo  1384  and  Gaumer  2498  to  refracta.  All 
these  are  riparia  proper.

for  B.  refracta  Brandeg.  by  0.  E.  Schulz  is  here  adopted.

A  species  with  lower  part  of  plant  having  aspect  usually  re- 
sembling that  of  Bidens  pilosa  L.  The  bipinnatifid  upper  leaves, 
however,  as  also  the  few  long  peduncles  and  the  radiate  flowering 
heads,  distinguish  it  easily  from  that  species.  Occasionally  the 
leaves,  all  or  nearly  all,  are  bipinnatifid,  giving  the  plant  a  very 
different  appearance.  Baker  described  the  ligulate  florets  as  being 
orange-colored,  but  a  number  of  dried  flowering  heads  observed  in 
herbaria  appear  to  have  the  ligules  more  of  a  reddish  brown  or 
cinnamon  color.  Fiebrig,  on  the  labels  for  his  No.  679,  describes  the 
ligules  as  fire-red  and  the  disc  florets  as  brown.  Hassler,  on  labels 
for  his  No.  4253,  describes  the  ligules  as  dark  purple  or  obscurely 
orange-colored.  We  may  note,  further,  that  long  before  Baker's  pub- 
lication of  Bidens  Gardneri,  Schultz  Bipontinus  had  designated  the 
Weddell  plant  (in  herb.)  as  Bidens  rubra,  evidently  for  the  very 
reason  that  its  rays  were  red. 

The  mature  fruiting  heads  are  noticeable  for  the  conspicuous 
retrorse  barbs  of  the  achenes,  these  barbs  suggesting  strongly  the 
teeth  of  a  comb.

styliferous  and  fertile  ray  florets,  also  by  the  achenes,  which  are 
parallel-sided  throughout  almost  their  entire  length.

In  general  habit  B.  brasiliensis  resembles  simple-leaved  plants  of 
B.  Riedelii  Baker  and  B.  Chodati  Hassler.  It  differs  from  the  former 
in  its  more  numerous  heads,  its  lack  of  ray  florets,  its  elongate, 
aristate  achenes,  etc. ;  from  the  latter,  in  its  wider  and  more  rhombic 
leaves,  more  numerous  heads,  smaller  involucres  with  much  more 
nearly  glabrous  and  less  numerous  bracts,  etc.  The  type  had  been 
collected  by  Saint  Hilaire  in  two  portions  representing  separately 
the  lower,  leafy  stem  and  the  branched,  fruiting  top.  Both  of  these 
are  taken  as  the  basis  for  the  description.

Par.;  Phila.;  Mus.  V.;  U.V.,  etc.). 

The  type  of  Bidens  angustissima  is  matched  very  well  by  Schultz 
Bipontinus'  type  of  the  var.  Linifolia,  except  that  the  latter  has  only 
simple  leaves,  while  the  former  has  tripartite  leaves.  Klatt,  in  pub- 
lishing the  description  of  his  B.  Linifolia,  described  the  heads  as  dis- 
coid, but  that  rays  were  present  on  at  least  the  Paris  material  is 
shown  by  Schultz  Bipontinus'  label,  in  his  own  handwriting,  which 
reads,  "achs.  rad.  calva.  .  .  .  '  Furthermore,  Pringle  collected 
many  fine  specimens  of  the  simple-leaved  form,  and  these  all  show 
orange-yellow  rays,  about  8  on  each  head.  The  only  difference  to 
be  found  between  the  two  species  is  the  questionable  one  of  foliage 
(cf.  Sherff,  Bot.  Gaz.  64:  34.  1917). 

At  Gray  Herbarium  there  is  a  single  sheet  (Coulter  375,  Mexico) 
with  three  slender  but  well  developed  specimens;  the  largest  one,  at 
the  left,  matching  the  type  of  B.  angustissima,  and  the  other  two,  at 
the  right,  matching  the  type  of  B.  Linifolia.  From  these  it  is  evident 
that  the  simple-leaved  form  does  not  merit  higher  than  varietal  rank. 

The  type  material  of  Coreopsis  linearifolia  DC.  (leg.  Keerl,  Tla- 
pujahua,  Mexico;  Del.)  I  have  not  seen.  I  rely  upon  the  determina- 
tion "Bidens  angustissima  H.B.K."  communicated  by  Dr.  S.  F.  Blake 
(in  lit.),  who  made  a  study  of  the  material  in  1924, l  also  the 
fact  that  DeCandolle  classified  his  species  among  those  having 
undivided  leaves.

Bidens  Schaffneri  to  specimens  of  this  species  sent  to  the  Gray 
Herbarium  and  to  the  Berlin  Herbarium. 

The  type  (Berlandier  1030)  is  matched  well  by  the  type  of  Bidens 
sarmentosa  Greenm.  (Pringle  11486)  and  that  of  Bidens  alpina 
Brandeg.  (Purpus  1648 — not  1684  as  erroneously  printed  in  Brandeg., 
loc.  cit.).  The  general  habit  suggests  strongly  that  of  Anthemis 
(A.  arvensis  L.) ,  whence  the  specific  name.  I  have  seen  two  old  speci- 
mens in  the  herbarium  of  Pavon  (Boiss.)  from  Mexico,  which  were 
evidently  cultivated  forms  belonging  here.  The  larger  one  is  more 
than  3.6  dm.  high;  the  smaller  one  bears  a  fruiting  head  with  achenes 
up  to  8  mm.  long  and  having  naked,  variously  spreading  or  even 
somewhat  reflexed  aristae  1.5-2  mm.  long.  These  are  the  Bidens 
bipinnatifida  Herb.  Pav.  (nee  aliorum). 

The  varying  treatments  accorded  this  species  have  been  dis- 
cussed in  earlier  papers  (Sherff,  op.  cit.,  1913,  1915,  and  1923). 
Recently  Bitter  has  published  the  new  name  Bidens  Purpusorum 
Bitt.  &  Petersen  for  a  plant  the  ripe  achenes  of  which  were  collected 
in  1908  by  C.  A.  Purpus  in  fields  in  the  vicinity  of  Esperanza, 
Vera  Cruz,  Mexico,  and  sent  to  the  Bremen  Botanical  Garden 
under  the  name  of  Bidens  grandi flora  Balb.  In  the  herbarium  of 
the  University  of  California  are  two  specimens  collected  by  Purpus 
and  bearing  field  data  essentially  similar  to  those  given  by  Bitter. 
The  first  was  collected  at  Esperanza  in  August,  1907,  not  "1908," 
and  matches  Bitter's  description  well.  The  second  was  collected  at 
Esperanza  in  1909,  and  distributed  under  the  name  of  "Bidens 
pilosa  Linn.?  Form."  It  is  Purpus  3634.  This  second  plant  differs 
in  being  more  branched  and  in  having  merely  3-5-parted  leaves,  not 
2-3-pinnatifid  leaves.1  Both  forms  have  most  of  the  achenial  aristae 
retrorsely  barbed,  but  in  this  and  other  respects  are  connected  with 
typical  Bidens  Anthemoides  by  a  large  number  of  herbarium  speci- 
mens examined. 

Similarly,  the  specimens  cited  above  (vide  sub  Hort.  Bot.  Hauni- 
ensi),  raised  at  the  Botanical  Garden  of  Copenhagen  from  the  achenes 
of  the  type  material  of  Bidens  Purpusorum  (Cop.),  are  found  to  be 
referable  at  once  to  Bidens  Anthemoides. 

The  type  material  for  B.  Anthemoides,  B.  sarmentosa,  and  B. 
alpina  was  in  each  case  the  more  common,  small,  alpine  form,  0.5-2 

1  In  a  number  of  species  of  Bidens  a  strong  degree  of  polymorphism  is  known 
to  occur  among  the  leaves;  for  example,  B.  aurea  (Ait.)  Sherff,  B.  triplinervia 
H.B.K.,  B.  andicola  H.B.K.,  B.  Chrysanthemifolia  (H.B.K.)  Sherff,  and  B.  squar- 
rosa  H.B.K.  The  difference  in  the  leaves,  therefore,  does  not  appear  to  be  of  much 
importance  in  this  case.

dm.  tall.  Taller  forms  are  sometimes  found,  the  taller  of  the  above- 
mentioned  Pavon  Herbarium  specimens  being  an  example.  The 
plant  collected  by  Henry  E.  Seaton,  No.  272,  was  over  4  dm.  tall. 
The  plants  cultivated  in  Bremen  from  achenes  sent  by  Purpus  grew 
about  5  dm.  tall.  An  exceptional  specimen  by  Schiede  from  Tepeya- 
hualco  (Berl.)  measures  over  5.7  dm.  in  height.  In  1917,  Professor 
H.  M.  Hall  of  the  University  of  California  sent  me  from  the  botanical 
garden  of  that  university  several  specimens  of  this  species  for  deter- 
mination. He  wrote:  "It  has  been  in  our  botanical  garden  for  a  long 
time  without  name  ....  It  is  rather  attractive  and  is  being  used 
to  some  extent  as  a  bedding  plant."  The  largest  specimen  measured 
about  4  dm.  high,  and  many  of  the  immature  achenes  had  aristae 
retrorsely  barbed.1  The  occasional  presence  here  of  retrorsely  barbed 
aristae  in  a  species  usually  lacking  them  demonstrates  again  the 
impracticability  of  using  the  presence  or  absence  of  such  aristae  as  a 
distinguishing  character  for  Bidens  and  Coreopsis  (cf.  Sherff,  Bot.  Gaz. 
59:  307.  1915).  For  147a.  Bid  ens  Muelleri  Sherff,  see  p.  645.

For  many  years  the  identity  of  the  South  American  Bidens  andi- 
cola  has  been  obscured  by  the  great  multiplicity  of  foliage  forms 
encountered.  Weddell,  as  early  as  1856  (Chloris  And.  1 :  70)  described 
it  as  a  polymorphous  plant  ("Plante  polymorphe  et  tres  repande  dans 
la  chaine,  mais  presque  exclusivement  alpestre").  Later,  Otto 
Kuntze,  who  like  Weddell  had  collected  in  South  America,  com- 
mented upon  the  variability  of  the  leaves  ("Eine  robuste  Art  mit 
einfach  oder  mehrfach  ternatisecten  Blattern,  mittelgrossen  gelben 
Strahlbliithen,  ziemlich  grossen  Bliithenkopfen,  ausseren  zottig 
behaarten  Involucralbracteen,  etc.,  aber  in  Bezug  auf  Blattheilung 
wie  manche  andere  Bidens-Art  sehr  variabel" ;  Rev.  Gen.  PI.  3,  pt.  2: 
136.  1898).  In  herbaria  the  numerous  foliage  forms  are  seen  to 
simulate  corresponding  forms  of  B.  triplinervia  H.B.K.  (B.  humilis 
H.B.K.,  B.  Crithmifolia  H.B.K.,  etc.),  and  this  has  led  often  to  con- 
fusion between  the  two  species.  Some  years  ago  I  was  enabled, 
through  the  courtesy  of  Dr.  Otto  Buchtien  (cf.  Sherff,  Bot.  Gaz. 
76:  151.  1923),  to  study  a  great  number  of  specimens  collected  by 
him  and  displaying  a  wide  range  of  variation.  From  these  (Field) 
and  many  others,  totalling  more  than  three  hundred  specimens,  the 
descriptions  for  B.  andicola  and  its  varieties  are  drawn.  It  was 
found  that  sometimes,  in  poorly  developed  material,  distinction  from 
B.  triplinervia  or  its  varieties  is  apparently  impossible,  but  that  in 
well  developed  material  the  distinctions  are  usually  very  definite,  B. 
andicola  being  coarser,  its  thicker  heads  having  commonly  about 
eight  instead  of  commonly  about  five  rays,  etc.  B.  andicola  has  the 
paleae  shorter  than  the  mature  achenes  and  even  this  character  alone 
separates  it  from  the  surprisingly  similar  aggregation  of  Mexican 
forms  of  B.  triplinervia  (Purpus  1547,  1548,  2637,  4135,  5089,  5620; 
Rose  &  Painter  6666,  7949;  Pringle  4915;  E.  W.  Nelson  3220,  etc.) 
that  in  late  years  have  passed  erroneously  under  the  name  B.  Dauci- 
folia  DC.  In  the  latter  the  paleae  are  usually  very  blackish  above 
and  commonly  surpass  the  mature  achenes. 

The  type  sheet  of  B.  fruticulosa  Mey.  &  Walp.  in  Berlin  bears 
two  small  specimens  collected  by  Mey  en  in  April,  1831,  about 
Tacora,  Peru.  The  leaves  are  undivided,  ovate  to  oblanceolate, 
and  only  about  1  cm.  long,  the  heads  6-8-ligulate.  The  plants 
match  very  closely  a  certain  form  found  among  the  Buchtien  plants

already  cited  (No.  4305),  and  thus  are  seen  to  be  merely  an  extreme 
form  of  B.  andicola. 

As  stated  in  a  former  article  (Bot.  Gaz.  85:  2.  1928),  Grise- 
bach's  B.  Cosmantha  var.  diversifolia  was  described  as  having  the 
lowermost  leaves  ternatisect,  the  others  entire,  elliptic-oblong, 
sharply  serrate.  It  came  from  the  Province  of  Catamarca,  Argen- 
tina. The  Catamarca  plants  studied  by  Grisebach  had  been  collected 
by  F.  Schickendantz  (Griseb.  op.  cit.  3).  A  good  specimen  of  F. 
Schickendantz  200,  from  Catamarca  and  bearing  the  determination 
B.  Cosmantha  var.  diversifolia  Griseb.,  is  extant  in  the  Berlin  Her- 
barium. It  is  merely  B.  andicola  H.B.K.

Occasionally  a  form  of  B.  andicola  is  found  with  the  leaves  highly 
compound  and  the  achenes  strongly  narrowed  above,  somewhat  like 
those  of  Cosmos.  If  it  were  not  for  various  connecting  forms  this 
would  seem  to  be  specifically  distinct.  Kuntze,  who  collected  speci- 
mens of  it,  referred  at  least  one  of  them,  a  plant  from  Cochabamba, 
Bolivia  (N.Y.)  to  B.  andicola,  naming  it  var.  decomposita.  In  a  care- 
less moment  he  named  a  precisely  identical  form  collected  between 
Cochabamba  and  Rio  Juntas,  Bolivia  (N.Y.)  B.  grandiflora  var. 
breviloba,  although  B.  grandiflora  (  =  B.  serrulata}  is  a  Mexican  species 
not  known  to  occur  in  South  America. 

To  Kuntze's  variety  decomposita  must  be  referred  Bidens  ma- 
crantha  Griseb.,  founded  on  a  plant  by  P.  G.  Lorentz,  No.  316, 
alpine  pastures  near  La  Cie"naga,  Argentina.  The  type  is  extant  in 
good  condition  (Berl.).  Although  lacking  mature  achenes,  it  matches 
very  closely  the  Bolivian  specimens  of  var.  decomposita,  except  in  the 
unimportant  respect  that  it  has  somewhat  larger  rays.

Grisebach's  type  of  B.  andicola  var.Cosmantha  was  P.O. Lorentz 
1526,  La  Cie'naga,  etc.  Identical  material  was  collected  by  Lorentz 
under  Nos.  540  and  5406  (Granadillas  near  Yacatula,  etc.).  These 
Lorentz  specimens  are  connected  with  B.  andicola  H.B.K.  by  too 
many  intermediate  forms  to  permit  their  being  regarded  as  specific- 
ally distinct.  They  may  best  be  considered  as  a  variety  of  B.  andi- 
cola, more  or  less  distinguished  from  the  species  proper  by  the  tall, 
slender  habit,  by  the  leaves  more  dissected  (but  less  so  than  in  var. 
decomposita  0.  Ktze.)  and  with  outlines  suggesting  those  of  celery 
(Apium  graveolens  L.),  also  by  the  (typically)  larger  flowering  heads, 
which  when  fully  expanded  reach  a  diameter  of  6-7  cm.

In  1916,  Otto  Buchtien,  the  eminent  South  American  collector, 
courteously  undertook  to  secure  for  me  as  wide  a  range  as  possible  of 
specimens  of  Bidens  from  South  America.  His  collections  since  then, 
as  well  as  his  earlier  collections,  all  mainly  from  Bolivia  and  Chile, 
have  been  received  and  deposited  in  the  Herbarium  of  Field  Museum. 
Not  only  do  some  of  them  throw  great  light  upon  heretofore  difficult 
points  as  to  the  variations  of  certain  species,  but  two  of  them  were 
found  to  be  apparently  new  to  science.  One  of  these  was  described 
under  the  name  B.  pseudocosmos.  The  other  was  at  first  regarded  as 
representing  a  new  species,  B.  Buchtienii.  Studies  of  the  more 
recently  collected  specimens  have  shown  indubitably  that  the  B. 
Buchtienii  plants  are  merely  a  subligulate  form  of  B.  andicola  var. 
Cosmantha.1 

Bidens  andicola  var.  d.  tarijensis  Sherff,  Bot.  Gaz. 
85:  14.  1928. 

Folia  plerumque  indivisa,  anguste  vel  late  oblongo-linearia, 
interdum  1-5-lobata  vel  3-5-partita,  segmentis  linearibus. 

Type  specimen:  Collected  by  Karl  Fiebrig,  No.  3460,  Tarija, 
Bolivia,  March  9,  1904  (Berl.). 

Distribution:  Southern  Bolivia. 

Specimens  examined:  Fiebrig  3004a  pro  parte,  Tarija,  in  1904 
(Berl.);  idem  3460  (type,  Berl.);  idem  3461  pro  parte,  alt.  3,200 
meters,  Calderillo,  March  22,  1904  (Berl.). 

The  specimens  cited  for  the  var.  tarijensis  (and  its  f.  dissecta, 
below)  come  from  the  little  known  territory  in  the  extreme  southern 
part  of  Bolivia,  close  to  the  Argentine  boundary.  They  are  graceful, 
mostly  glabrous  plants,  growing  up  to  a  meter  in  height.  They  have  a 
habit  more  characteristic  of  B.  triplinervia  H.B.K.  (with  which  they 
were  at  first  confused  by  me),  but  the  heads  are  rather  uniformly  8- 
rayed,  as  in  B.  andicola.  The  variety  proper  is  seen  to  be  comparable 
with  the  var.  hirtella  of  B.  triplinervia.  In  var.  tarijensis,  however, 

1  Recently  Buchtien  has  reported  (in  lit.  March  27,  1932)  that  B.  andicola 
(meaning  var.  Cosmantha  in  particular)  has  rays  often  4  cm.  long,  but  usually  3  cm., 
and  as  short  as  2  cm.  only  on  very  dry  spots  of  ground.  He  reports  further  that  the 
Buchtienii  forms  are  always  radiate  but  with  rays  only  2-3  mm.  long.  He  has 
"never  seen  plants  which  form  a  transition  from  the  one  to  the  other."  For 
practical  purposes  of  identification,  it  may  be  remarked  that  dried  herbarium 
specimens  of  f.  Buchtienii  often  appear  entirely  discoid. 


504  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

there  is  observed  the  very  strong  tendency  to  produce  a  form  with 
the  leaves  divided  into  3-5  elongate-linear  segments.  This  form 
(f .  dissecta)  is  very  different  in  general  habit  from  other  known  forms 
of  B.  andicola  with  compound  leaves.1

of  2,200  meters,  Tarija,  Bolivia,  March  13,  1904  (Berl.).

Bidens  andicola  var.  «.  Mandonii  Sherff,  Bot.  Gaz. 
80:  380.  1925. 

A  specie  differt:  saepius  annua,  altior  (usque  ad  8  vel  10  dm. 
alta),  minus  ramosa  et  magis  attenuata;  capitulis  ad  anthesin  sub- 
radiatis,  minoribus,  tantum  circ.  5  mm.  latis  et  5-7  mm.  altis,  achae- 
niis  gracilioribus. 

Type  specimen:  Collected  by  Gustave  Mandon,  No.  48,  in 
uncultivated  places  at  altitude  of  2,650-2,680  meters,  San  Pedro, 
Bolivia,  March,  1859  (Boiss.). 

Distribution:   Bolivia  and  northernmost  Argentina. 

Specimens  examined:  Otto  Buchtien  9105,  alt.  3,200  meters, 
Unduavi,  North  Yungas,  Bolivia,  October,  1931  (Field) ;  P.  G.  Lorentz 
&  G.  Hieronymus,  cattle  ranches  at  foot  of  Nevado  del  Castillo, 
Prov.  Salta,  Argentina,  March  19,  1873  (Berl.,  2  sheets);  Mandon

idem  48  (type,  Boiss.:  cotypes,  Brit.;  Kew). 

Mr.  Gustave  Beauverd,  in  1919,  had  referred  my  type  doubtfully 
to  a  variety  of  B.  pilosa  L.  The  fruiting  heads,  however,  are  more 
those  of  B.  andicola.  Mandon  44,  collected  at  the  same  time  and 
place,  offers  several  transitional  forms  that  connect  this  variety 
satisfactorily  with  typical  B.  andicola.  In  fact,  the  Boissier  Herba-

Tarija,  Bolivia,  March  22,  1904  (Berl.)-  This  was  collected  the  same  day  as  the 
Calderillo  plants  (No.  3461),  at  a  slightly  different  altitude  in  a  nearby  locality. 
Its  leaves  are  tripartite  and  more  as  in  normal  forms  of  B.  andicola.

Bidens  affinis  Kl.  &  0.  was  described  from  specimens  raised 
from  seed  sent  by  E.  Otto.  A  number  of  good  specimens  are  in 
the  older  herbaria  (Herb.  Bernhardi  in  Mo.;  Mus.  V.;  Par.;  etc.). 
Specimens  obtained  in  August,  1841,  at  the  Strasburg  Botanical 
Garden  (Hort.  Argent.)  and  elsewhere  from  seed  sent  from  Berlin 
(where  Klotzsch  was  Keeper  of  the  Royal  Herbarium,  fide  Pritzel, 
Thes.  165.  1872)  are  in  the  private  herbarium  of  Schultz  Bipontinus 
(Par.).  These  were  determined  by  him  as  B.  triplinervia  H.B.K. 
O.  E.  Schulz  (in  Urban,  Symb.  Antill.  7:  143.  1911)  likewise  equates 
B.  affinis  with  5.  triplinervia.  In  1914  I  compared  the  B.  affinis 
specimens  with  the  type  and  Bonpland  duplicate  of  B.  triplinervia 
(Par.)  and  found  them  identical.2 

Asa  Gray  (Proc.  Amer.  Acad.  22:  429-430.  1887)  suspected  B. 
triplinervia  of  being  a  form  of  B.  heterophylla  Ort.;  i.e.,  of  B.  aurea 
(Ait.)  Sherff.  The  two  species  do  actually  resemble  each  other  in 

1  Here  may  be  mentioned  C.  G.  Pringle  7895,  alt.  2,850  meters,  Sierra  de 
Pachuca,  Hidalgo,  Mexico,  September  14, 1899  (U.S.);  idem  7908,  alt.  3,000  meters, 
eodem  loco,  October  6,  1899  (Gray);  idem  8255,  eodem  loco,  October  5,  1899  (Berl.; 
Boiss.;  Brit.;  Can.;  Cam.;  Del.;  Field;  Gray;  Kew;  Mun.;  Mus.  V.;  Par.,  2  sheets; 
Petrop.;  Phila.;  U.S.,  etc.).    These  are  tall,  robust  forms,  appearing  at  first  as  if 
abnormal  forms  of  Bidens  serrulata.     Most  of  the  specimens  have  simple  leaves 
and  these  vary  greatly  in  outline  (from  ovate-lanceolate  to  rotund)  and  hispidity 
Cdensely  hispid  to  glabrous).    No.  7908  has  the  ovate,  simple  leaves  very  incisely 
toothed  with  about  5-7  long  teeth  on  each  side,  giving  the  same  pectinate  appear- 
ance noted  by  Schultz  Bipontinus  in  certain  specimens  of  Mandon  50  from  Bolivia. 
In  a  number  of  cases,  however,  the  foliage  is  fairly  typical  for  B.  triplinervia. 

Whether  the  bizarre  vegetative  variations  observed  among  these  Pringle 
plants  from  the  upper  slopes  of  Sierra  de  Pachuca  are  indicative  of  hybridization 
with  one  or  two  neighboring  species  can  only  be  surmised  at  this  time. 

2  The  Berlin  Herbarium  contains  the  two  sheets,  already  cited,  of  fine  material 
collected  near  Angangueo,  Michoacan,  Mexico,  October,  by  Schiede,  also  several 
garden  specimens  cultivated  in  1833  at  Berlin,  doubtless  from  seed  of  the  Schiede 
specimens.

their  simple-leaved  states,  but  B.  triplinervia's  longer  achenes  are 
very  distinctive. 

Bidens  pedunculata  Phil,  was  based  upon  Frederick  Philippi  217, 
Sibaya,  Province  of  Tarapaca,  Chile.  I  have  not  seen  the  type, 
although  the  first  above  cited  specimen,  from  Tarapaca,  may  be 
from  the  original  collection.  Reiche  (Fl.  Chile  4:  102.  1905),  who 
without  doubt  has  studied  the  type,  equates  B.  pedunculata  with  B. 
serrata  Pav.,  but  this  latter  has  more  slender  leaves  than  called  for  by 
Philippi's  description  ("foliis  inferioribus  ....  ovato-lanceolatis") 
and  is  better  referred  to  var.  hirtella.

Type  specimen:  Collected  by  Alexander  Humboldt  and  Aime 
Bonpland,  probably  at  Quito,  Ecuador,  1799-1803  (Par.). 

Distribution:  Colombia,  Ecuador,  and  Peru. 

Specimens  examined :  Bro.  Ariste-Joseph  A42,  Bogota,  Colombia, 
1916  (U.S.);  M.  T.  Dawe  302,  sabana  or  plain  of  Bogota,  Colombia, 
communic.  1916  (Kew);  Humboldt  &  Bonpland,  probably  at  Quito, 
Ecuador,  1799-1803  (types  of  Bidens  hirtella  H.B.K.  and  B.  pro- 
cumbens H.B.K.;  Par.);  iidem,  Quito,  eodem  tempore  (Par.);  Ruiz, 
Pavon,  and  Dombey  977,  Peru,  1788  (Del.;  type  of  Bidens  serrata 
Pav.  ex  DC.);  J.  Triana  1374  pro  parte  (Par.,  cum  var.  macrantha 
commixt.). 

The  type  locality  of  B.  hirtella  H.B.K.  and  of  B.  procumbens 
H.B.K.  was  not  definitely  known  to  Kunth.  In  the  case  of  the 
former,  he  surmised  (H.B.K.  loc.  cit.)  that  the  plant  had  grown  with 
B.  triplinervia  H.B.K.,  which  was  known  to  have  been  collected  in 
Mexico  ("prope  San  Augustin  de  Las  Cuevas  et  urbem  Mexici"). 
In  the  case  of  the  latter,  he  surmised  that  it  had  grown  near  Jalapa 
("Xalapa"),  Mexico.  An  extra  sheet  of  original  material  matching 
the  type  of  B.  hirtella  and  of  the  identical  B.  procumbens  was  in  the 
Bonpland  Herbarium,  which  was  given  later  to  the  Paris  Herbarium. 
This  was  clearly  of  the  same  collection  as  the  two  types  mentioned. 
It  had  been  labeled  (by  Spach,  fide  L.  Anfrayi  coram  me  in  mense 


510  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

Augusto  anno  1914)  B.  procumbens,  and  had  come  from  Quito, 
Ecuador.  Without  doubt  the  types  of  B.  hirtella  and  of  B.  pro- 
cumbent, which  had  upon  their  labels  no  data  as  to  locality 
(except  "Ame'rique  Equatoriale"),  came  from  the  same  locality, 
Quito,  Ecuador. 

In  a  former  paper  (Bot.  Gaz.  80:  383.  1925),  I  have  treated  B. 
triplinervia  as  having  two  sets  of  forms  with  divided  leaves  (var. 
mollis  and  var.  macrantha),  and  one  set  with  undivided  leaves  (the 
species  proper).  From  this  last  set  may  properly  be  segregated 
the  forms  with  slender  leaves  as  var.  hirtella.  Kunth  described  the 
leaves  of  this  variety  as  lanceolate,  but  they  are  variously  linear- 
lanceolate,  widely  linear-oblong,  or  narrowly  oblong-lanceolate. 
The  affinity  with  B.  triplinervia  is  evidenced  by  the  mostly  5-rayed 
heads,  which  probably  alone  distinguish  the  variety  from  the  corre- 
sponding var.  tarijensis  of  B.  andicola  H.B.K. 

To  var.  hirtella  must  be  referred  B.  serrata  Pav.  ex  DC.  The 
type  (No.  977  of  the  Ruiz,  Pavon,  and  Dombey  expedition,  Peru,  in 
1788;  cf.  Lasegue,  Mus.  Bot.  Deless.  244-247.  1845)  is  extant  in  the 
DeCandolle  Prodromus  Herbarium  (Del.).  It  lacks  flowers,  as 
stated  by  DeCandolle,  but  has  some  leaves  undivided  and  lanceolate 
or  narrowly  oblong,  others  somewhat  incised  or  lobed  at  the  base.

As  stated  in  an  earlier  paper  (Bot.  Gaz.  61:  500.  1916),  the  two 
type  specimens  from  which  Kunth  described  B.  Crithmifolia  and  B. 
Delphinifolia  are  still  extant  in  good  condition  (Par.).  Both  are  from 
Ecuador l  and  differ  only  in  the  slightly  diverse  foliage.  The  immature 
type  of  B.  Crithmifolia  is  matched  exactly  by  J.  J.  Triana  1374  pro 
parte  (Par.),  a  specimen  collected  near  Bogota,  Colombia,  which  is 
superior  in  showing  not  only  flowering  heads  but  also  numerous 
achenes.  These  achenes  are  mainly  2-aristate,  but  some  are  3-aris- 
tate  and  so  agree  perfectly  with  achenes  of  B.  Delphinifolia.2  Fortu- 
nately, I  have  found  another  specimen  by  Triana  of  the  same  number 
in  the  British  Museum  of  Natural  History,  and  this  shows  the 
slightly  different  foliage  of  B.  Delphinifolia,  for  which  it  might  well 
be  taken  to  represent  a  supplementary  type. 

1  Kunth  (loc.  cit.)  expressed  uncertainty  as  to  the  locality  whence  B.  Del- 
phinifolia had  come,  but  Bonpland's  duplicate  specimen  (Par.)  has  the  original 
label  marked  "XI  Quito." 

2  It  is  interesting  to  note  that  the  mature  head  on  the  type  of  B.  Delphinifolia 
has  at  least  one  achene  that  is  2-aristate,  showing  no  indication  of  a  third  awn's 
ever  having  been  present  (cf.  H.B.K.  loc.  cit.,  "triaristata").

There  is  great  variation  in  foliage.  Triana  1375  (Brit.)  shows  one 
plant  with  leaves  tripartite,  the  leaflets  being  incisely  dentate,  and 
another  plant  with  the  simple,  ovate-lanceolate  leaves  of  B.  tri- 
plinervia  proper.  In  fact,  the  sheet  of  Triana  1374  in  Paris  bears 
another  specimen  (besides  that  cited  above)  which  has  similarly 
simple,  ovate-lanceolate  leaves;  and  still  another  specimen  of 
Triana  1374  at  Paris  has  the  slender,  undivided  leaves  of  var. 
hirtella.  Evidently  Triana  did  not  differentiate  in  the  field  between 
the  two  types  of  simple  leaves  or  between  these  and  the  finely 
divided  ones. 

In  1914,  on  comparing  the  simple-leaved  spontaneous  state 
(Triana  1374  pro  parte  and  1375  pro  parte,  also  Goudot,  ditches, 
Fontibon,  February  20,  1844)  with  the  mature  B.  affinis  and  imma- 
ture B.  triplinervia  material,  I  was  impressed  with  their  similarity. 
I  searched,  but  in  vain,  for  any  authentic  material  of  B.  affinis  mani- 
festing the  divided  leaves  so  much  more  common  than  undivided 
ones  on  B.  Crithmifolia.  Later,  I  was  permitted,  through  the  kindness 
of  Dr.  Alex.  Zahlbruckner  to  study  the  large  set  of  Bidens  specimens 
in  the  Natural  History  Museum  of  Vienna  and  found  three  more 
sheets  of  the  original  B.  affinis  material.  These  display  numerous 
gradations  from  the  typical  undivided,  lanceolate  leaves  of  B.  affinis 
to  the  bipinnate  leaves  characteristic  of  B.  Crithmifolia.  The 
plants  are  a  little  larger,  but  this  doubtless  was  due  to  cultivation. 
The  floral  and  achenial  characters  are  identical.  The  plants  with 
decompound  foliage  (B.  Crithmifolia,  B.  Delphinifolia,  etc.)  are, 
therefore  (cf.  Bot.  Gaz.  76:  156.  1923),  not  more  than  varietally 
distinct  from  B.  affinis  Kl.  &  0.  and,  hence,  from  its  equivalent, 
B.  triplinervia  H.B.K. 

Because  of  the  great  rarity  of  the  form  with  undivided,  ovate- 
lanceolate  leaves  (B.  triplinervia  proper)  and  the  evolutionary 
detachment  from  this  simple-leaved  form  that  the  various  forms  with 
divided  leaves  manifest  to-day,  it  seems  wisest  to  associate  without 
distinction  all  the  cut-leaved  forms,  except  vars.  mollis  and  nema- 
toidea,  under  the  earliest  varietal  name,  var.  macrantha.  Accordingly, 
this  has  been  done  in  the  present  treatment. 

B.  humilis  H.B.K.,  the  type  of  which  also  came  from  Ecuador, 
is  not  varietally  distinct  from  B.  Crithmifolia  and  therefore  reduces, 
likewise,  to  var.  macrantha  (cf.  Weddell,  Chlor.  And.  1:  69.  1855: 
"Le  B.  Crithmifolia  H.B.K.  et  le  B.  delphinifolia  H.B.K.  sont  tres 
voisins  de  cette  espece  B.  humilis,  dont  ils  ne  sont  meme  peut-etre 
que  des  formes  a  feuilles  moins  divise"es,  et  a  lanieres  plus  allonge"es";

also  Jameson,  Syn.  PL  Aequator.  2: 117. 1865:  "a  B.  crithmifolia  et  B. 
delphinifolia  vix  distincta  videtur.").  B.  consolidaefolia,  described 
by  Turczaninow  from  Jameson  693,  collected  at  Quito,  is  a  form 
with  finely  divided,  very  pubescent  leaves  (cf.  Turcz.  Ann.  Bot. 
Syst.  5:  225.  1858:  "Accedit  ad  definitionem  B.  humilis  H.B.K.  sed 
ligulae  duplo  majores,  achaenia  minime  scabra  et  forte  laciniae  folior. 
angustiores."). 

B.  decomposita  var.  hirsutior  was  described  by  Clarke  (cf.  Bot. 
Gaz.  61:  500.  1916)  from  a  single  specimen  collected  by  him  at  an 
altitude  of  over  2,200  meters,  in  the  Nilgiri  Mountains  of  British 
East  India.  Later  he  informed  J.  D.  Hooker  (cf.  Fl.  Brit.  Ind.  3:  310. 
1881)  that  he  supposed  it  to  be  some  cultivated  plant.  Hooker 
admits  having  seen  no  specimen  of  it,  but  it  happens  that  Clarke's 
original  specimen  ("11207. . .  23  March  1870 . . .  coll.  C.  B.  Clarke.")  was 
sent  to  Kew  Herbarium  in  1877  and  is  still  there  in  good  condition. 
The  plant  is  very  different  from  Bidens  decomposita  Wall.,  but  its 
villous,  finely  divided  leaves  match  fairly  well  Jameson  693,  the  type 
collection  of  B.  consolidaefolia  Turcz.  It  matches  also  a  number  of 
other  South  American  specimens  of  B.  triplinervia  var.  macrantha. 
In  the  same  region  of  India  Dr.  Watt  collected  material  (Watt  2160) 
that  agrees  with  Clarke's  specimen  except  that  it  is  minutely  pubes- 
cent as  to  leaves  and  glabrous  as  to  stems.  Still  more  specimens 
from  this  region  occur  (e.g.,  Thomson,  Eclipse  Exped.,  Nilgiri  Hills, 
December,  1871,  determined  on  sheet  as  "Bidens  humilis  H.B.K.," 
in  Kew;  and  R.  H.  Beddome  4511,  "introd.?  a  common  weed," 
Nilgiri  Hills,  in  Brit.),  some  of  them  glabrous  and  some  pubescent 
but  all  indistinguishable  from  B.  triplinervia  var.  macrantha.  A 
study  of  these  specimens,  all  collected  in  the  same  region  at  about 
the  same  time,  and  by  two  of  the  collectors  suspected  of  being 
introduced,  shows  beyond  doubt  that  they  were  merely  forms  of  B. 
triplinervia  var.  macrantha  carried,  perhaps  in  ballast,  from  South 
America  to  the  southwest  shores  of  British  East  India.1 

At  times,  dwarfed,  immature  forms  of  B.  andicola  H.B.K.  decep- 
tively resemble  the  var.  macrantha  and  thus  frequently  have  been 
confused  with  it  in  herbaria.  B.  serrulata  (Poir.)  Desf.  (B.  grandi- 
flora  Balb.)  appears  really  distinct  from  var.  macrantha,  despite  the 
implication  of  Dr.  Otto  Kuntze's  name  B.  grandiflora  var.  humilis 
(cf.  0.  E.  Schulz  in  Urban,  Symb.  Antill.  7:  139.  1911:  "Sine  dubio 
pleraque  specimina  ab  0.  Kuntze  I.e.  commemorata  ad  species 

1  Cf.  Fyson  (Fl.  Nilgiri  and  Pulney  Hill-tops  above  6500  feet  1:  237.  1915), 
who,  though  omitting  historical  details,  lists  B.  humilis  from  South  America  as  an 
introduction  into  the  Nilgiri  Hill  region.

propinquas  pertinent,"  a  criticism  justified  also  by  Kuntze's  incor- 
rect association  of  Clarke's  var.  hirsutior  with  B.  pilosa  L.  Kuntze's 
combination  derived,  perhaps,  from  the  fact  that  in  certain  localities 
of  Mexico  (e.g.,  Mt.  Orizaba  and  Sierra  de  Pachuca)  a  few  plants  of 
var.  macrantha  (i.e.,  of  B.  humilis  H.B.K.)  are  found  with  a  more 
robust  growth  habit,  suggesting  somewhat  that  of  B.  serrulata  (Poir.) 
Desf.  (i.e.,  of  B.  grandiflora  Balb.). 

The  several  original  specimens  of  B.  Artemisiaefolia  Poepp.  & 
Endl.  still  extant  (Mus.  V.;  Berl.)  are  the  form  of  var.  macrantha 
with  tomentose  pubescence  and  2-3-pinnatifid  leaves.  They  match 
rather  closely  the  original  material  of  B.  decomposita  var.  hirsutior 
and  B.  consolidaefolia.  They  were  collected  by  Poeppig,  No.  1378, 
in  "Peruvia  subandina.  In  montibus  apertis  calidis  ad  Cassapi.

The  type  of  Bidens  mollis  Poepp.  &  Endl.,  Poeppig  1377,  was 
found  growing  with  the  type  material  of  B.  Artemisiaefolia  (referred 
above  to  B.  triplinervia  var.  macrantha).  Its  achenes  were  immature 
and  the  leaves  tripartite.  In  pubescence,  floral  characters,  and 
general  habit  it  was  similar  to  the  B.  Artemisiaefolia  specimens. 
The  peculiar  outline  of  the  leaf  divisions,  however,  would  seem  at 
first  to  suggest  B.  andicola  more  strongly.  Spruce  5047  matches 
the  B.  mollis  type  very  closely.  Spruce  5049  (Brit.)  and  5894  (Gray) 
match  Spruce  5047  minutely  except  that  they  show  the  leaves  finely 
divided,  as  in  B.  Artemisiaefolia.  These  and  other  similar  consid- 
erations show  beyond  all  doubt  that  B.  mollis  belongs  to  B.  tripli- 
nervia, is  merely  a  foliage  form,  and,  as  such,  should  be  accorded 
no  higher  than  varietal  rank.

Type  specimen:  Collected  by  H.  L.  Viereck,  No.  5,  Cerro  Que-

Distribution:  Known  only  from  Province  of  Santa  Marta,

Specimens  examined :  H.  H.  Smith  1980,  rare  on  open  lands,  alt.

H.  L.  Viereck  5  (type,  U.S.). 

In  1913  the  Smith  plant  from  Santa  Marta  was  noted  as  a 
singular  foliage  form  and  photographs  (my  photograph  No.  341)  were 
distributed  to  several  herbaria.  Recently  I  have  been  sent  the 
Viereck  plant,  collected  in  the  same  locality  and  revealing  similar 
characters.  On  both  specimens  the  segments  of  the  very  numerous 
and  pinnately  or  more  often  bipinnately  parted  leaves  are  strikingly 
thread-like.  Otherwise  the  plants  are  like  those  of  the  very  common 
var.  macrantha  (Wedd.)  Sherff.1

1  The  capitula  are  5-rayed;  the  mature  achaenia  (6-8  mm.  long)  are  exaristate 
(as  sometimes  happens  in  the  var.  macrantha  too)  and  are  somewhat  surpassed 
by  the  paleae.  Smith  reported  the  plants  as  growing  erect  and  up  to  18  inches  high.

The  general  habit,  so  far  as  can  be  inferred  from  the  single 
branch  examined,  is  somewhat  similar  to  that  of  Bidens  Geraniifolia 
and  B.  triplinervia  var.  macrantha.  The  foliar  segments  are  especially 
acute,  however,  and  the  unbarbed  achenial  aristae  should  render 
distinction  easy.

Distribution:  Guatemala  on  Volcan  de  Agua  and  very  rare  north-

Specimens  examined:  Virl.  d'Aoust  404,  State  of  San  Luis  Po- 
tosi, Mexico,  1851  (Par.) ;  Maxon  &  Hay  3690,  alt.  3150-3,300  meters,

Dr.  S.  F.  Blake  examined  Bertoloni's  type  which  he  found  (July 
21,  1925)  in  the  Bertoloni  Herbarium  at  Zola  Pedrosa,  near  Bologna, 
Italy.1  He  states  (in  lit.)  that  he  is  satisfied  that  my  determination 
of  Maxon  &  Hay  3690  as  B.  canescens  Bertol.  is  correct.  Bertoloni's 
description  was  so  full  and  detailed  that  the  topotypes  collected  by 
Maxon  and  Hay,  and  by  Salvin  and  Godman,  could  anyway  be 
identified  with  his  species  without  the  slightest  room  for  doubt. 
Authentic  specimens  with  mature  achenes  are  much  to  be  desired, 
that  the  relationship  of  this  species  with  its  closest  ally,  Bidens 
andicola  var.  decomposita  0.  Ktze.,  may  be  investigated  more 
extendedly.

THE  GENUS  BIDENS  529 

grandiflora  Balb.,  a  name  going  back  to  1812.  The  trivial  name 
serrulata  was  employed  by  Poiret  one  year  earlier,  and  must  be  taken 
up.  Certain  authentic  specimens  of  Poiret's  species  are  extant  at 
Paris,  where  this  plant  once  was  cultivated  for  at  least  several  years. 
One  of  them  ("Du  Jardin  des  Plantes  de  Paris.  5  Aout  1813")  was 
photographed  by  me.  They  are  specifically  the  same  as  the  plants 
cultivated  by  the  younger  Jacquin  in  1810  from  seed  sent  from  Paris 
(Mus.  Hist.  Nat.,  located  in  the  Jardin  des  Plantes),  under  the  name 
Bidens  quinqueradiata  Zea  and  named  by  Jacquin,  Coreopsis  diversi- 
folia.  They  are  matched  specifically  also  by  the  type  illustration 
of  Cosmea  lutea  Sims.1 

The  cultivated  specimens  found  in  herbaria  are  mostly  lower, 
more  delicate,  and  less  erect,  giving  an  illusory  appearance  of  dis- 
similarity to  the  spontaneous  form.  Poiret's  description  was  based 
upon  one  of  Desfontaines'  specimens.  Like  many  of  the  descriptions 
written  in  those  days,  it  was  inadequately  drawn.  The  fruit  characters 
were  omitted.  We  read  that  the  plant  described  is  small,  with 
petioles  and  lower  part  of  stem  pilose,  also  with  ovate  leaves.  These 
last  were  not  described  as  compound. 

DeCandolle  (loc.  cit.),  evidently  relying  solely  upon  Poiret's 
description,2  maintained  B.  grandiflora  apart  from  B.  serrulata  (Poir.) 
Desf .  The  Index  Kewensis  (1 :  617. 1895),  however,  equates  Coreopsis 
serrulata  Poir.  and  Bidens  grandiflora  Balb.  Furthermore,  we  are 
bound  to  consider  the  very  careful  and  extended  description  of  the 
Poiret  species  drawn  up  by  Cassini  (loc.  cit.)  when  publishing  the 
new  combination  Kerneria  serrulata.  Cassini  had  been  in  Paris,  at 
the  center  of  Desfontaines'  and  Poiret's  activities.  He  amplified  his 
description  from  living  material  growing  in  the  Royal  Garden  of 
Paris,  where  Desfontaines  had  worked.  His  description  fitted  very 
well  the  average  plants  of  B.  grandiflora  Balb. 

Upon  the  grounds  of  priority  the  name  B.  serrulata  takes  pre- 
cedence, going  back  to  some  time  in  the  year  1811  prior  to  November 
29,3  while  B.  grandiflora  was  not  published  until  1812.  The  exact 
date  for  Coreopsis  diversifolia  Jacq.  I  do  not  know.  The  page  num- 
ber and  plate  number  would  seem  clearly  to  indicate  a  date  later 
than  1811.  At  all  events,  the  existence  of  a  B.  diversifolia  Willd. 

1  A  species  native  to  Mexico,  cultivated  from  seeds  obtained  from  the  Madrid 
Botanical  Garden;  drawing  made  in  1812.    Stem  purplish  at  base  in  illustration.

The  plant  of  Ghiesbreght  (No.  551)  was  referred  erroneously  by

Less.  It  matches  the  type  of  B.  chiapensis  very  precisely.  A  dis- 
tinguishing character  of  the  species  is  the  large  number  (12-20)  of 
narrowly  linear  exterior  involucral  bracts.

THE  GENUS  BIDENS  537 

Type  specimen:  Collected  by  C.  Hoist,  No.  76,  in  sunny  places 
of  the  higher  mountains,  mountain  steppe,  Usambara,  German  East 
Africa,  October,  1891  (Berl.). 

Distribution:  District  of  Usambara,  German  East  Africa. 

Specimens  examined:  Karl  Braun  2820,  Kingo-Kwai,  western 
Usambara,  August  21, 1909  (Berl) ;  idem  2857,  eodem  loco  et  tempore 
(Berl.) ;  Hoist  76  (type,  Berl.) ;  Albrecht Zimmermann  1776,  Hermanns- 
platte,  western  Usambara,  February,  1908  (Berl.). 

Hoffmann's  type  in  Berlin  consists  of  three  flowering  specimens 
mounted  upon  one  sheet.  They  lack  mature  or  even  submature 
achenes.  At  first  they  were  determined  by  him  as  Coreopsis  Grantii 
Oliv.  (Bidens  Grantii  Sherff),  but  later  he  crossed  out  this  determi- 
nation and  substituted  the  new  name  C,  Holstii.  His  description  of 
the  achenes  ("Achaeniis  juvenilibus  alatis")  was  of  necessity  drawn 
from  the  unripened  ovaries.  The  winged  character  assigned  by  him 
to  the  young  achenes  is  not  manifest  on  my  examination  of  them. 
They  naturally  are  thin  and  delicate  toward  the  edges,  but  this  is 
true  of  the  achenes  of  many  typical  Bidens  species  when  equally 
young.  Fortunately  there  since  have  been  collected  by  Braun  and  by 
Zimmerman  additional  specimens  from  the  type  district,  Usambara. 
These  match  the  type  very  closely,  and  two  excel  it  in  having  mature 
achenes.  The  achenes  are  linear,  unwinged,  3-6  mm.  long,  flattened, 
antrorsely  setose  upon  the  margins  and  at  the  apex,  exaristate  or  with 
two  setae  very  slightly  larger  than  the  rest  and  representing  minute 
aristae.  Hoffmann  described  the  aristae  as  very  short  ("aristis  2 
brevissimis"),  but,  as  may  be  seen  from  my  plate,  fig.  g,  the  ovarian 
aristae  of  his  type,  when  compared  with  the  body  of  the  ovary,  are 
not  very  short.  The  species  bears  a  strong  habital  resemblance  to 
Bidens  Grantii  (Oliv.)  Sherff  and  in  lesser  degree  to  Coreopsis  pin- 
natipartita  0.  Hoffm.  From  the  latter  it  differs  in  its  setose,  exalate 
achenes.  From  B.  Grantii  it  appears  to  differ  mainly  in  having  the 
achenes  exaristate  or  only  shortly  aristate  (a  character  here  of  some- 
what uncertain  value)  and  in  the  nature  of  its  pubescence.

As  already  stated  (Sherff,  loc.  cit.),  the  two  type  specimens  are 
extant  in  fairly  good  condition.  Their  several  mature  achenes  are 
seen  on  close  inspection  to  be  devoid  of  true  wings  (cf.  Peters,  loc. 
cit.,  "achaeniis  oblongis  subcompressis  marginatis  sed  vix  alatis"), 
and  to  have  merely  rough,  thickened  margins,  similar  to  those  on 
certain  species  of  true  Bidens,  e.g.,  B.  aristosa  (Michx.)  Britt.  In  a 
previous  paper  (Bot.  Gaz.  59:  305-308.  1915)  I  have  stated  the 
reasons  for  regarding  such  plants  as  belonging  to  Bidens. 

Coreopsis  Mattfeldii  Sherff  (Bot.  Gaz.  76:  83. 1923)  bears  a  strong 
superficial  resemblance  to  Bidens  Steppia,  but  can  easily  be  dis- 
tinguished by  its  achenes  and  involucral  bracts.  The  many  mature 
achenes  on  the  type  of  C.  Mattfeldii  differ  remarkably  from  the 
ones  on  the  type  and  other  specimens  (already  cited)  of  B.  Steppia. 
For  B.  Steppia  they  are  (at  most)  widely  oblong-linear  in  outline, 
7.5-9  mm.  long  and  2.5-3  mm.  wide;  there  is  merely  a  thickened 
lateral  ridge,  wings  being  absent.  For  C.  Mattfeldii  the  achenes  are 
much  thinner  and  wider,  the  outer  obovate,  6-8  mm.  long  and 
4.25-5  mm.  wide,  the  inner  oblanceolate,  about  8  mm.  long  and  4 
mm.  wide;  all  are  winged,  and  even  on  submature  fruiting  heads  the 
rounded  upper  ends  of  the  wings,  adjacent  to  the  aristae,  are  easily 
visible.  The  external  bracts  about  equal  the  inner  ones  in  C.  Matt- 
feldii; in  B.  Steppia  they  tend  to  exceed  the  inner  ones  by  at  least 
2-6  mm.

small  size,  those  of  B.  kivuensis,  but  the  general  foliage  habit  and 
habit  of  flowering  heads  are  more  as  in  B.  Steppia.

parte,  in  marshy  places  on  the  left  bank  of  the  Caringa  River, 
Ambaca,  Angola,  Portuguese  West  Africa,  June,  1855  (Brit.). 

Distribution:  Known  only  from  Angola.

vicinity  of  River  Gola  Luije,  Malange,  June,  1925  (Kew) ;  Welwitsch 
3272  pro  parte  (type,  Brit.). 

The  type  has  the  general  habit  of£.  Steppia  proper  but  differs 
in  the  small,  slender  achenes.  The  existence  of  the  var.  leptocarpa, 
as  also  of  several  transitional  forms  between  B.  Steppia  proper  and 
var.  leptocarpa,  shows,  in  my  opinion,  that  the  achenial  distinctions 
for  the  ambacensis  type  are  varietal  rather  than  specific.

Type  specimen:  Collected  by  John  Gossweiler,  No.  4176,  among 
the  ferruginous  rocks  near  the  fort  at  Kabango,  Principality  of 
Amelia,  Angola,  Portuguese  West  Africa,  December,  1907  (Brit.). 

Distribution:  From  eastern  Southern  Rhodesia  to  Angola. 

Specimens  examined:  Ex  Dept.  Agriculture,  No.  2482,  Salisbury, 
Southern  Rhodesia  (Kew);  Mrs.  0.  Craster  211,  eodem  loco,  com- 
munic.  May  27,  1914  (Kew);  Gossweiler  4176  (type,  Brit.). 

At  the  time  of  writing  the  original  description  of  Bidens  rufo- 
venosa,  there  were  at  hand  only  my  large  photograph  of  the  type 
and  a  small  fragment  which  had  been  lent  me.  The  one  leaf  on  this 
fragment  had  the  pubescence  along  the  veins  of  the  lower  leaf -sur- 
faces conspicuously  red-tomentose.  The  habitat  cited  by  Goss- 
weiler, "amongst  ferruginous  rocks,"  led  at  once  to  the  thought  that 
iron  in  some  form  had  been  taken  from  the  soil  into  the  roots,  then 
carried  through  the  stem  and  leaves  to  the  lower  leaf  surfaces  and 
deposited  there,  doubtless  as  an  oxide  of  iron.  This  view  having 
been  rejected  by  an  eminent  plant  physiologist  to  whom  it  had 
been  stated,  the  leaf  was  given  for  study  to  Dr.  Sophia  H.  Eckerson, 
then  of  the  University  of  Chicago.  She  reported  the  color  of  the 
pubescence  as  due  to  a  red  stain  produced  in  the  mucilage  cells 
along  the  veins.  Apparently,  then,  the  stain  afforded  a  character  of 
diagnostic  value. 

More  recently  I  have  reexamined  the  type.  Only  certain  leaves 
possessed  the  rufo-tomentose  character.  Furthermore,  the  thickish 
root  was  covered  with  a  deposit,  of  the  reddish  color  noted  in  the  hairs 
on  some  of  the  lower  leaf -surfaces,  but  other  material  examined  lacks 
the  red.  Clearly  the  rufo-tomentose  character  is  here  a  fickle  one, 
doubtless  being  entirely  dependent  upon  the  "ferruginous"  nature 
of  the  rocks  or  soil  in  the  habitat.

Distribution:  Known  only  from  southeasternmost  portion  of 
Belgian  Congo. 

Specimens  examined:  Bequaert  389  (type,  Bruss.);  idem  563,

In  the  herbarium  at  Brussels  are  two  sheets  labeled  J.  Bequaert 
389.  One  bears  a  specimen  having  fairly  large  flowering  heads 
(2.5-4  cm.  wide)  with  red  or  violaceous  ligules  and  moderately  thick, 
not  elongated  achenes.  This  sheet  bears  Bequaert's  original  field 
label  and  clearly  is  the  one  kept  mainly  in  mind  by  De  Wildeman 
when  he  named  and  described  Bidens  rubra.  It  is,  moreover,  the 
main  basis  of  my  description.  The  other  sheet  bears  a  very  different 
plant  with  small  (7-8  mm.  wide),  discoid  flowering  heads  and  slender, 
elongated  achenes.  This  second  specimen  matches  the  type  of 
Bidens  ciliata  De  Wild.  (=B.  paupercula  Sherff),  i.e.,  Bequaert  302, 
and  doubtless  was  really  a  duplicate  of  the  B.  ciliata  type,  but 
through  some  error  in  mounting  was  given  the  wrong  number.  It

was  unfortunately  confused  by  De  Wildeman  with  his  B.  rubra,  as  is 
shown  by  his  erroneously  describing  the  achenes  of  B.  rubra  as 
elongate,  up  to  about  15  mm.  long.

Mt.  Kundelungu,  Belgian  Congo,  May  10,  1908  (Berl.). 
Distribution:  Belgian  Congo. 

Specimens  examined:  Kassner  2725  (type,  Berl.);  F.  G.  Overlaet, 
Kafakumba,  April,  1925  (Berl.;  Field,  3  sheets;  Kew). 

Appears  closest  in  foliage  and  general  habit  to  B.  urceolata 
De  Wild.,  a  species  also  collected  by  Kassner  (No.  2710)  on  Mt. 


552  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

Kundelungu.1  B.  leptolepis  has  smaller  flowering  heads,  very  dark 
red  or  dark  purple,  not  light  violet  ligules,  much  more  slender  and 
elongate  external  involucral  bracts,  ordinary  (not  conspicuously 
margined  above)  internal  involucral  bracts,  and  lacks  a  definitely 
urceolate  shape  to  the  tubular  florets. 

It  was  described  originally  from  the  single  type  specimen  by 
Kassner.  Shortly  afterward  I  was  able  to  enlist  the  friendly  co- 
operation of  Mr.  F.  G.  Overlaet  of  Belgium.  In  April,  1925,  Mr. 
Overlaet's  official  duties  had  taken  him  to  Kafakumba,  Belgian 
Congo,  where  he  collected  several  handsome  specimens  of  this 
Bidens.  These,  together  with  various  other  Congo  specimens  found 
by  him,  were  forwarded  to  me  and  are  now  deposited  in  the  herbaria 
cited.  They  afford  a  much  broader  and  more  representative  notion 
of  the  species  than  was  possible  from  the  lone  type  specimen.  The 
achenes  are  mature,  the  leaves  are  mostly  more  divided,  with  shorter 
and  broader  segments,  and  the  external  involucral  bracts  are  often 
more  numerous  than  in  the  type  and  also  often  shorter  and  less 
noticeably  narrowed.  The  rays  of  the  two  dozen  or  more  flowering 
heads  examined  vary  from  dark  red  to  densely  dark  purplish-red,  as 
in  the  type.  With  the  aid  of  these  additional  specimens  the  above 
amplified  description  has  been  drawn.

Hildebrandt's  No.  2432  was  collected  in  quantity  and  proved  to 
be  new  (Bidens  Hildebrandtii).  Specimens  were  distributed  to 
several  herbaria.  His  2432a,  though  collected  at  the  same  time  and 
place,  seems  to  have  been  rare,  for  apparently  only  a  single  specimen 
was  found,  and  that  none  too  ample.  The  habit  seems  nearest  that 
of  Bidens  Fischeri  (0.  Hoffm.)  Sherff,  of  German  East  Africa.  From 
that  it  differs  in  being  more  nearly  glabrous,  in  having  the  exterior 
involucral  bracts  also  the  achenes  much  wider,  etc.

Kew);  T.  Wakefield,  Galla  Country,  eastern  tropical  Africa,  May, 
1880  (Kew;  forma  plus  gracilis);  J.  M.  Wood  1231,  Umzinyati  Falls, 
Inanda,  Natal,  March  11  (Kew,  recept.  September,  1881). 

The  material  originally  given  by  Schultz  Bipontinus  the  manu- 
script name  Bidens  Buchingeri  and  later  given  the  name  B.  Schimperi 
var.  pilosa  was  collected  by  Schimper  at  Gaha-Meda  near  Dschad- 
scha,  Abyssinia.  The  specimens  examined  by  me  in  Schultz  Bipon- 
tinus' herbarium  (Par.)  are  merely  a  somewhat  pilose-leaved  but 
glabrous-stemmed  form  of  B.  Schimperi.  We  must  therefore  follow 
the  course  of  Oliver  and  Hiern  (Oliver,  Fl.  Trop.  Afr.  3:  394.  1877) 
and  treat  these  names  as  synonymous. 

Many  species  of  Bidens  are  polymorphic  as  to  foliage,  and  yet 
reasonably  constant  as  to  characters  of  flower  and  fruit,  but  B. 
Schimperi  offers  an  amazing  range  of  variation  in  all  respects.  Thus, 
in  typical  B.  Schimperi  the  external  bracts  of  the  involucre  become 
10-17  mm.  long,  but  in  forms  of  the  species  (of  which  B.  acutiloba 
Sherff  must  be  considered  one)  these  may  become  only  3-6  mm. 
long.  Again,  in  typical  material,  the  achenial  bodies  range  in  length 
from  0.9-2.2  cm.,  while  in  various  forms  these  range  as  low  as  3-6  mm. 
long.  Oliver  and  Hiern,  also  Otto  Hoffmann,  in  their  work  on  the 
African  flora  came  to  recognize  a  large  number  of  these  forms  as 
merely  variations  of  B.  Schimperi,  although  to  a  novice  these  would 
seem  separate  species. 

Bidens  prolixa  S.  L.  Moore  was  founded  upon  C.  F.  M.  Swynnerton 
1884,  northern  Melsetter  at  alt.  60-180  meters,  Rhodesia,  April,  1907 
(Brit.).  Moore  (loc.  cit.)  distinguished  this  plant  from  B.  Schimperi 
by  "its  slender  habit  with  long  stalked  heads,  its  smaller  leaves  with 
narrower  lobes,  its  smaller  heads,  shorter  involucres  and  narrower 
ligules."  Upon  comparison  with  a  considerable  number  of  specimens 
of  B.  Schimperi,  B.  prolixa  is  found  to  be  connected  much  too  closely 
for  specific  separation. 

B.  punctata  Sherff  (PL  CXLII,  figs,  i-q)  was  founded  upon  two 
sheets  of  material  (Kew)  consisting  of  small  plants  with  leaves 
tripartite  or  even  entire,  not  bi-  or  tripinnate  as  in  ordinary  B. 
Schimperi.  Their  outer  involucral  bracts  were  noticeably  shorter 
than  the  inner  ones.  The  fruiting  characters  were  very  similar  to 


558  FIELD  MUSEUM  OF  NATURAL  HISTORY— BOTANY,  VOL.  XVI 

those  of  B.  prolixa,  and  I  therefore  came  later  to  regard  B.  punctata 
and  with  it  the  less  extreme  B.  prolixa  as  representing  a  variety  (var. 
punctata)  of  B.  Schimperi.  The  diagnostic  characters  are  found, 
however,  to  be  so  uncorrelated  and  so  prone  to  appear  in  different 
combinations,  that  it  seems  difficult  to  justify  maintenance  of  even 
varietal  rank  for  the  prolixa  or  punctata  forms.

proper.  It  was  collected  at  Handeni,  German  East  Africa,  February, 
1920,  and  has  a  habit  suggesting  that  of  the  South  American  Bidens 
Andrei.

exterior  involucral  bracts  9-13,  linear-lanceolate  or  even  narrowly 
linear,  strongly  attenuate  above,  finally  more  or  less  reflexed,  6-11 
mm.  long;  also  anomalous  inner  paleae,  which  are  widely  elliptic  or 
obovate  or  truncate,  the  apex  conspicuously  and  to  a  great  length 
linearly  elongated,  surpassing  the  spreading-awned  achenes.  The 
habit  is  that  of  Bidens  Kirkii  (Oliv.  &  Hiern)  Sherff,  but  the  fewer

heads  of  B.  Hoffmannii,  the  shorter,  more  often  lobed  and  less  par- 
allel-sided leaf  divisions,  and  the  retrorsely  barbed  awns  of  the  longer 
achenes  distinguish  it  easily  from  B.  Kirkii.  The  species  was  named 
in  honor  of  Dr.  Otto  Hoffmann,  who  not  only  studied  this  and  other 
material  collected  by  Volkens,  but  during  his  lifetime1  contributed  in 
a  most  important  way  to  knowledge  of  the  African  species  of  Bidens.

566  FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XVI 

Type  specimen:  Collected  by  Franz  Ludwig  Stuhlmann,  No.  6403, 
Maramo,  Mkamba  (Mgambo),  District  of  Usaramo,  German  East 
Africa,  January,  1894  (Berl.). 

Distribution:  Near  Indian  Ocean  Coast,  easternmost  German 
East  Africa. 

Specimens  examined:  W.  Holtz  406,  sandy  soil,  light  places, 
Sachsenwald,  Dar-es-Salaam,  December  6,  1901  (Berl.) ;  Stuhlmann 
6403  (type,  Berl.);  idem  7584,  Dar-es-Salaam,  1894  (Berl.);  idem 
8470,  Dar-es-Salaam,  September,  1894  (Berl.). 

The  two  sheets  of  material  (Stuhlmann  6403  and  7584)  cited  by 
Otto  Hoffmann  for  his  var.  gracilior  differ  from  his  species  proper 
(Coreopsis  exaristata  0.  Hoffm.  =  Bidens  microcarpa  Sherff)  in  having 
the  leaves  less  glandular-pubescent  or  sometimes  even  glabrate,  their 
divisions  finer  and  much  more  acute  or  even  acuminate,  the  involucre 
less  pubescent  and  the  achenes  not  only  3-4  mm.  long  with  all 
except  the  innermost  ones  oblanceolate,  but  rather  4.5-6  mm. 
long  and  all  linear.  The  important  achenial  differences  seem  to  have 
been  overlooked  by  Hoffmann.1  A  specimen  collected  later  by 
Holtz  (No.  406,  Dar-es-Salaam,  German  East  Africa,  December  6, 
1901)  in  the  immediate  vicinity  of  the  type  locality,  Usaramo,2 
agrees  fairly  well  with  the  type  as  to  foliage  and  involucre,  and  has 
likewise  longer  achenes.  These  important  characters  of  foliage  and 
achenes  appear  to  entitle  Hoffmann's  variety  to  separate  specific  rank. 

Bidens  gracilior  var.  /3.  ukerewensis  Sherff,

Folia  bi-tripinnatipartita,  segmentis  ultimis  linearibus  moderate

tenuiter  biaristatis  aristis  0.5-1  mm.  longis  apice  retrorsum  1-4-

Type  specimen:  Collected  by  Carl  Uhlig,  No.  19,  abundant  along 
the  shore  line  of  Lake  Victoria  Nyanza  (Lake  Ukerewe),  Ukerewe, 
German  East  Africa,  April  20,  1904  (Berl.). 

1  Many  mature  achenes  on  the  type,  Stuhlmann  6403,  have  1  or  2  minute 
aristae  (0.2-0.3  mm.  long)  and  several  have  these  aristae  retrorsely  barbed  with 
1  or  2  barbs.     Had  Hoffmann  noticed  this  character  he  certainly  would  have 
remarked  upon  it,  probably  even  referring  his  specimen  not  to  Coreopsis  but 
to  Bidens,  since  with  him  the  retrorse-barb  character  was  considered  diagnostic 
of  the  genus  Bidens  (cf.  Sherff,  Bot.  Gaz.  59:  305-308.  1915).

From  most  African  species  of  Bidens  this  is  easily  distinguished 
by  its  minute  achenes.  The  absence  of  wings  as  well  as  of  any  other 
distinctly  Coreopsoid  character  made  the  transfer  to  Bidens  seem 
advisable. 

The  habitat  is  in  the  tropical  forest  up  to  1,600  meters  or  more  in 
the  mountains,  ploughed-up  areas  in  the  virgin  forest,  low  bush, 
edges  of  plantings,  etc.

In  1908,  T.  Kassner  spent  at  least  several  weeks  among  and 
around  the  Kundelungu  Mountains,  southwest  of  Lake  Moero,  in 
southeastern  Belgian  Congo.  Among  his  plants  received  at  the 
Botanical  Garden  of  Berlin  were  no  fewer  than  four  new  species  of 
Bidens  and  Coreopsis.1  Besides  these  he  collected  (Kassner  2710) 
the  violet-rayed  Bidens  urceolata  DeWild.,  described  previously 
(Ann.  Mus.  Congo,  Bot.  IV.  1: 167.  1903)  from  a  specimen  (No.  464) 
obtained  in  1900  by  Verdick  at  Lukafu,  a  locality  in  this  same 
region;  also  (Kassner  2859a)  the  red-rayed  Bidens  rubra  DeWild., 
described  more  recently  (Repert.  Sp.  Nov.  13:  203.  1914)  from 
specimens  (J.  Bequaert  389,  Homble  563)  obtained  at  Welgelegen. 

DeWildeman  (Ann.  Mus.  Congo  IV.  2: 169. 1913)  has  referred  this 
plant  to  Bidens  Kirkii  (Oliv.  &  Hiern)  Sherff  (Coreopsis  Kirkii 
Oliv.  &  Hiern).  A  study  of  various  specimens  of  Bidens  Kirkii  in 
European  herbaria,  however,  shows  several  pronounced  distinctions. 
Bidens  Kirkii's  rays  are  light  yellow,  not  dark  or  brownish  orange- 
yellow;  its  exterior  involucral  bracts  are  mostly  obtuse  at  the  apex 
and  below  the  apex  noticeably  dilated ;  its  immature  achenes  are  not 
widest  at  the  apex  as  in  S.  palustris,  nor  are  they  practically  glabrous, 
and  their  aristae  are  upwardly  hispid,  with  numerous  weak  hairs, 
not  downwardly  barbed  with  a  few  spinulose  hooks;  finally,  B. 
Kirkii  does  not  appear  from  collectors'  data  to  be  a  swamp-inhabiting 
species  as  B.  palustris  was  observed  to  be.

Type  specimen:  Collected  by  Johannes  Mildbraed,  No.  9777,  at 

altitude  of  about  1,000  meters,  Buar,  Kamerun,  July,  1914  (Kew). 

Distribution:  Known  only  from  type  locality  in  the  Kamerun. 

Specimens  examined:  Mildbraed  9386,  alt.  about  1,000  meters, 
Buar,  May,  1914  (Kew);  idem  9777  (type,  Kew). 

The  two  sheets  examined  are  of  material  collected  two  months 
apart.  The  first  sheet  has  two  plants,  collected  in  May.  One  has  a 
sterile,  leafy  stem  about  2.7  dm.  tall;  the  other  has  a  sterile  stem 
about  2.4  dm.  tall  and  a  fertile  stem  about  6.2  dm.  tall,  bearing  three 
fruiting  heads.  The  leaves  are  of  the  more  compound  type  and  offer 
a  strong  superficial  resemblance  to  those  of  the  North  American 
Coreopsis  Delphinifolia  Lam.  The  exterior  involucral  bracts  are 
equal  to  or  a  fourth  or  third  shorter  than  the  interior  ones.  The 
achenes  are  the  larger  ones  of  the  Latin  description. 

The  second  or  type  sheet  bears  material  of  a  much  better  devel- 
oped plant  (or  plants),  collected  in  July.  About  two  dozen  heads 
are  present.  The  leaves  are  simple  or  laterally  2-lobed.  The  exterior 
involucral  bracts  tend  to  greatly  exceed  the  interior  ones.  The 
achenes  are  the  smaller  ones  of  the  Latin  description. 

As  these  differences  appear  to  be  of  a  seasonal  nature,  it  seems 
inadvisable  to  attempt  any  varietal  distinction  of  one  form  from 
the  other.

Type  specimen:  Collected  by  W.  E.  Taylor,  in  the  bed  of  a  tor- 
rent in  a  ravine  at  Rabai,  Seyidie  Province,  British  East  Africa,  Janu- 
ary 5,  1886  (Brit.). 

Distribution:  Equatorial  Africa  from  east  to  west  coasts. 

Specimens  examined:  John  Gossweiler  3165,  Cutchi  River  near 
the  fort,  Cutchi,  Angola,  May  4,  1901  (Brit.);  Taylor,  in  torrent  bed 
in  a  ravine,  Rabai,  etc.  (type,  Brit.). 

Moore  describes  this  species  as  "verisimiliter  perennis."  Goss- 
weiler's  label  says  "like  perennial."  While  perhaps  having  a  peren- 
nial root,  the  plant  has  somewhat  the  aspect  of  an  annual.  Its  tall 
habit  and  smooth,  very  delicate,  elongate,  wiry  branches,  characters 
especially  well  marked  in  Gossweiler's  plant,  are  distinctive.  The 
heads  look  much  like  those  of  Bidens  Kirkii  (0.  &  H.)  Sherff . 

The  remarkably  discontinuous  distribution  displayed  by  B. 
Taylori  in  its  occurrence,  so  far  as  at  present  known,  only  at  or  near 
the  opposite  coasts  of  Africa,  led  at  first  to  my  suspecting  that  the 
species  might  prove  to  be  only  a  form  of  some  older  and  better  known 
species.  It  has  been  impossible,  however,  to  find  justification  for 
reducing  B.  Taylori  to  synonymy  with  any  other  species.

A  species  close  to  Bidens  Elliotii,  but  having  only  about  8  ray 
florets,  the  about  8  exterior  involucral  bracts  only  5-7  mm.  long  and 
scarcely  equalling  the  interior,  and  the  achenial  aristae  downwardly 
barbed.  In  B.  Elliotii  the  ray  florets  number  mostly  10-14,  the 
usually  9-12  exterior  bracts  are  more  often  8-11  mm.  long,  and  the 
achenial  aristae  are  erectly  hispid.  B.  Phalangiphylla  is  close  also  to 
B.  Bequaertii  DeWild.,  but  has  the  much  larger  and  more  openly 
dissected  leaves,1  narrower  exterior  involucral  bracts,  and  much 
smaller  fruiting  heads  with  smaller  achenes.

Easily  distinguished  from  all  other  species  of  Bidens  by  the 
numerous  acute,  finally  spreading  exterior  involucral  bracts  and 
the  peculiar  inner  paleae,  which  are  membranous-winged  below  and 
with  greatly  extended,  exalate  apex  running  upwardly  and  surpass- 
ing the  bodies  of  the  achenes.  My  description  of  the  mature  achenes 
is  drawn  from  the  mature  specimen,  Braun  5372  (BerL),  collected  at 
a  spot  (Lulangula)  close  to  the  type  locality  of  Mininga.  The  achenes 
simulate  those  of  certain  Hawaiian  species  in  having  the  aristae 
attached  somewhat  below  rather  than  at  the  top  of  the  achene  body.

Otto  Hoffmann,  in  his  original  determination  of  Baum's  plant, 
treated  it  as  a  new  species.  Whether  he  did  so  because  at  that  time 
he  was  unfamiliar  with  Bidens  andongensis  Hiern,  or  because,  al- 
though familiar  with  Hiern's  species,  he  felt  Baum's  plant  to  be 
distinct,  I  am  unable  to  say.  However,  he  later  (Kunene-Sambesi 
Exped.  420.  1903)  referred  the  Baum  specimen  to  B.  andongensis 
Hiern.  Since  the  main  differences  lay  in  the  size  and  shape  of  the 
involucres,  also  the  number  and  shape  and  proportionate  size  of  the 
exterior  involucral  bracts,  one  might  indeed  have  suspected  that 
Baum  had  collected  merely  an  atypic  and  less  robust  form  of  B. 
andongensis.  The  various  specimens  sent  in  more  recently  by  Goss- 
weiler  to  the  British  Museum  of  Natural  History  show  similar 
peculiarities  as  to  these  characters,  thus  strengthening  the  belief 
that  we  have  to  do  with  a  distinct  species. 

The  species  was  named  in  honor  of  the  late  Spencer  L.  Moore  of  the 
British  Museum  of  Natural  History,  who  had  done  much  admirable 
work  upon  the  African  species  of  Bidens,  and  who,  independently, 
had  interpreted  the  Gossweiler  plants  as  typifying  a  new  species.

A  specie  differt  achaeniis  verrucatis;  his  plerumque  5-8-aristatis, 
saepe  praeterea  4-10  levibus  acutis  aristulis  coronatis. 

Type  specimen:  Collected  by  John  Gossweiler,  No.  3021,  Angola, 
April,  1906  (Brit.). 

Distribution:  Angola. 

Specimens  examined :  Gossweiler  3021  (type,  Brit.). 

A  form  so  peculiar  in  fruit  characters  that  it  is  perhaps  best 
treated  for  the  present  as  a  variety.  Various  considerations  indicate 
no  basis  for  regarding  it  as  a  separate  species.  The  achenes  are 
minutely  warty  and  5-8-aristate  (commonly  with  3  long  aristae  and 
2-5  short  ones,  with  frequently  4-10  additional  rudimentary,  smooth, 
sharp  aristae  completing  a  crown).  The  variety  is  seen  to  be  com- 
parable, in  its  relation  to  the  species  proper,  with  the  var.  verrucifera 
Moore  of  Bidens  crocea  Welw.  In  its  large  number  of  aristae  it  makes 
a  singular  approach  to  Ericentrodea  mirabilis  (Sherff)  Blake  &  Sherff, 
a  plant  that  differs  widely  in  other  respects.

In  an  earlier  article  (Bot.  Gaz.  59:  312.  1915)  I  have  stated  that 
Gossweiler's  3631  may  properly  be  taken  as  representative  of  this 
species.  In  many  respects  both  Gossweiler's  plant  and  Hiern's  type

achenial  aristae  only  sparsely  barbed  and  the  few  barbs  near  the  base 
are  erect,  not  retrorse;  furthermore,  the  rays  (15-18)  are  more  numer-

are  ever  as  narrowly  petiolate  as  in  some  cases  with  B.  andongensis.

THE  GENUS  BIDENS  595 

Klatt  (loc.  cit.)  described  the  achenial  aristae  as  glabrous,  but  a 
study  of  ten  immature  achenes  removed  from  the  one  large  flowering 
head  on  the  type  sheet  shows  all  the  aristae  to  be  downwardly  barbed 
near  the  apex  and  upwardly  barbed  near  the  base.  The  inner  bracts 
of  the  involucre,  which  are  shorter  than  the  outer,  the  more  numer- 
ous rays,  and  the  peculiarly  barbed  aristae  appear  to  distinguish  this 
species  sufficiently  from  B.  andongensis  Hiern. 

We  may  note  that  in  a  second  publication  (Ann.  Naturh.  Hofmus. 
Wien  7:  103.  1892)  Klatt  repeated  his  description  of  this  species 
with  only  slight  changes  but  cited  Von  Mechow's  No.  394  instead 
of  the  Buchner  plant.  However,  Von  Mechow  394  does  not  repre- 
sent B.  Buchneri  and  must  be  discarded.1

There  are  two  ample  specimens  of  the  type.  Their  achenes  are 
wingless  and  the  aristae  lack  barbs.  A  specimen  from  Uganda 
(Dawe  415)  has,  however,  many  of  the  aristae  retrorsely  barbed  at 
the  apex.  This  last  specimen  I  had  described  in  manuscript  as  a 
new  species,  but  later  found  it  specifically  identical  with  the  type 
specimens  of  Coreopsis  Seretii.  It  may  be  remarked  that,  had  De- 
Wildeman  relied  upon  the  more  significant  presence  or  absence  of 
achenial  wings  instead  of  the  presence  or  absence  of  retrorse  aristal 
barbs  (cf.  Sherff,  Bot.  Gaz.  59:  308.  1915),  he  would  have  had  no 
hesitation  in  placing  the  species  in  Bidens  at  the  outset.

fairly  large  and  much  better  specimen  by  Stuhlmann,  though  cited  after  Meyer's, 
was  clearly  the  type  from  which  Hoffmann's  description  was  drawn.

the  type  of  B.  Buchneri  (Buchner  31)  it  does,  indeed,  offer  a  strong 
resemblance.  In  fact,  I  have  suspected  that  through  further  such 
forms  as  Von  Mechow  394,  B.  grandis  may  be  proved  to  pass  into 
B.  Buchneri  and  perhaps  even  be  shown  to  be  conspecific.  Certain  it 
is  that  distinction  is  impossible  in  some  cases  except  upon  the  ques- 
tionable basis  of  upwardly  (B.  grandis)  versus  downwardly  (B. 
Buchneri)  barbed  aristae.1  For  the  present  it  seems  wise  to  await 
more  positive  data  before  attempting  to  merge  the  two.

but  the  original  field  tag  on  the  cotype  at  Kew  gives,  as  the  type 
locality,  Kavirondo,  some  400  kilometers  to  the  east.1  Both  the 
type  and  the  cotype  consisted  merely  of  fragments  from  the  inflores- 
cence. Thus  the  original  description  was  necessarily  very  faulty 
and  misleading  as  to  general  habit,  size  of  leaves,  etc.  Fortunately, 
there  have  been  received  at  Kew  several  additional  specimens  from 

1  The  name  ruwenzoriensis  was  not  entirely  inappropriate,  since  Mt.  Ruwenzori 
was  Elliot's  destination,  and  his  herbarium  labels  bear  the  heading,  "Ruwenzori 
Expedition."

the  same  general  region,  which  show  the  species  to  be  a  tall,  hand- 
some perennial,  doubtless  reaching  a  height  of  2  meters,  although 
Small  reported  it  as  growing  2-3  feet.  As  the  mutual  identity  of 
all  these  specimens  admits  of  no  doubt,  I  have  taken  advantage  of 
them  to  draw  up  a  fresh  and  amplified  description  of  the  species. 

The  type  proper  of  B.  coriacea  consists  of  seven  fragments  from 
the  inflorescence,  which  offer  at  least  a  superficial  resemblance  to  the 
type  of  B.  ruwenzoriensis.  Indeed,  Moore  (loc.  cit.)  appears  to  have 
suspected  them  of  being  the  same.  In  the  B.  coriacea  type  the  outer- 
most involucral  bracts,  as  noted  by  Moore,  are  not  noticeably  longer 
than  the  inner  ones,  and  the  achenes  are  mainly  triaristate.  In  the 
type  material  of  B.  ruwenzoriensis,  also  in  the  material  by  Diimmer,by 
Small,  by  Snowden,  and  by  Whyte,  the  outermost  bracts  are  easily 
the  longest  and  the  achenes  are  biaristate.  In  a  former  article  (Bot. 
Gaz.  81 :  52. 1926)  I  pointed  out  the  similarity  between  the  two  forms. 
Since  then  I  have  studied  the  material  by  Sir  Evan  James,  which  has 
the  achenes  biaristate  as  in  the  type  of  B.  ruwenzoriensis,  but  the 
outermost  bracts  not  much  longer  than  the  others.  With  this 
connecting  form  at  hand,  there  appears  no  justification  for  attempt- 
ing further  retention  of  B.  ruwenzoriensis  as  a  separate  species.

Native  name  said  to  be  "maharrama."  The  foliage  strongly 
suggests  in  outline  that  of  some  species  of  Crataegus.  Hoffmann  (loc. 
cit.)  described  the  ovaries  as  winged,  but  a  careful  search  through  his 
type  material  shows  that  he  used  the  term  carelessly,  for  there  is 
no  trace  of  definite  wings  such  as  are  usually  found  in  true  Coreopsis.

bush  region,  southwestern  Meru,  German  East  Africa,  October  21, 
1904  (Berl.) ;  idem  480,  alt.  1,600  meters,  in  meadows,  above  Enzonzo 
Enzare,  November  13,  1901  (Berl.);  Georg  Volkens  398,  alt.  1,500 
meters,  abundant  on  grassy  plateau,  Distr.  Uschiri,  Kilimanjaro, 
June  14,  1893  (Berl.;  Brit.);  idem  537,  alt.  1,200  meters,  among 
bushes  on  road  to  the  steppe,  Distr.  Marangu,  German  East  Africa, 
July  6,  1893  (Berl.;  Hamb.). 

The  branches  as  preserved  in  herbaria  have  the  appearance  of 
having  come  from  a  large,  coarse  herb.  Uhlig,  however,  labeled 
his  No.  414  a  shrub  ("Strauch  d.  Strauchregion")  and  Volkens,  in 
labeling  his  own  No.  537,  likewise  described  it  as  a  shrub  ("Strauch 
bis  2  m.  hoch").  The  other  collectors  are  silent  upon  this  point. 
Hoffmann's  description  (loc.  cit.)  of  the  species  as  a  shrub  doubtless 
was  based  upon  Volkens'  label.  It  is  doubtful,  however,  if  the  plants 
form  true  woody  shrubs  (frutices)  in  the  common  sense  of  the  term. 

The  discontinuous  distribution  shown  by  the  occurrence  of  this 
species  in  Angola  as  well  as  in  British  and  German  East  Africa  is 
notable.  The  Angola  plant  (Gossweiler  3640)  was  carefully  compared 
with  Kassner  870  from  British  East  Africa  and  found  to  match  well.

"the  technical  characters  of  Wedelia;  the  general  appearance  of  the

In  the  young  heads  (much  before  anthesis)  the  exterior  bracts 
are  twice  as  long  as  the  disc,  with  a  resulting  fanciful  resemblance 
of  these  heads  to  the  medusa  stage  of  many  of  the  Coelenterata  in 
the  animal  kingdom.

Distribution:  Northeasternmost  Belgian  Congo. 

Specimens  examined:  Jurion  41  (Mus.  Cong.,  2  type  sheets). 

Apparently  most  closely  allied  to  B.  Dielsii  var.  medusoides, 
from  which  it  differs  in  its  stouter,  straighter,  and  more  rigid  stem, 
its  more  slender  and  elongate  leaves,  its  much  more  numerous  and 
paniculately,  not  corymbosely,  disposed  heads,  etc.

identical  plant,  with  one  fruiting  head  and  the  several  leaves  more  compound  and 
more  noticeably  setigerous-toothed.  As  no  additional  field  data  are  given  under 
this  second  specimen,  it  may  well  be  that  the  two  belonged  to  the  same  collection.

THE  GENUS  BIDENS  629 

Type  specimen :  Cultivated  in  garden  of  J.  Veitch  and  Sons,  1908, 
from  material  collected  by  Captain  Diespecker  in  British  East  Africa 
(Kew,  2  sheets). 

Distribution:  British  East  Africa. 

Specimens  examined:  Hort.  Veitchii  et  filiorum  (Kew,  2  type 
sheets). 

The  first  type  sheet  has  the  six  flowering  heads  measuring  about 
2.2-2.7  cm.  across,  with  about  12-16  exterior  bracts.  The  second 
type  sheet  has  likewise  six  flowering  heads,  but  these  are  mostly 
4-4.5  cm.  across  and  the  exterior  bracts  number  16-22.  These 
differences  are  construed  as  representing  different  states  of  luxuri- 
ance due  to  conditions  of  cultivation.

E  specie  achaeniis  exaristatis  sed  pappo  brevi  plus  minusve

Type  specimen:  Collected  by  Wilhelm  Schimper,  No.  766,  at 
margins  of  groves  in  valleys  near  Adoa,  Abyssinia,  November  12, 
1838  (Par.,  2  sheets).1 

Distribution:  Abyssinia  and  perhaps  Eritrea. 

Specimens  examined :  Schimper  766  (2  type  sheets).2 

The  achenes  of  this  variety  lack  aristae  but  have  the  pappus 
more  or  less  definitely  coroniform  or  cup-shaped  (whence  the 
name  Microlecane  given  by  Schultz  Bipontinus).  Tegetmeyer  (0. 
Hoffm.  loc.  cit.)  has  illustrated  this  peculiar  pappus  in  its  extreme 
development. 

In  his  original  treatment  Schultz  Bipontinus  referred  this  form, 
as  representing  a  subgenus,  to  Chrysanthellum.  The  affinity  with 

1  The  two  type  sheets  of  Chrysanthellum  abyssinicum  at  Paris  both  bear  the 
number  578.    A  printed  distribution  label  also  is  present  on  the  first  type  sheet 
and  this  has  the  number  766  in  print  with  the  citation  "Fl.  Ratisb.  Anni.  1842 
pag.   440,   ubi  per  errorem  plantae  numerus   578   tribuitur."     In   his   original 
description  Schultz  Bipontinus  gave  Schimper's  number  as  "it.  abyss.  Sect.  II.  no. 
578,"  but  later,  in  Walpers'  Repertorium,  he  gave  it  as  "1078."    Just  why  these 
discrepancies  arose  is  not  clear,  but  there  can  be  no  question  as  to  the  authenticity

that  genus  seems  purely  fallacious.  Bentham  and  Hooker  (loc. 
cit.)  elevated  the  subgenus,  which  Schultz*  Bipontinus  had  named 
Microlecane,  to  the  rank  of  a  genus  separate  from  Chrysanthellum. 
However,  through  Bidens  setigera  and  B.  setigeroides  the  type  mate- 
rial of  Microlecane  is  too  closely  allied  with  Bidens  to  justify  generic 
segregation.  Thus,  for  example,  B.  setigera  has  very  long,  slender 
aristae  and  many  of  the  achenes  are  much  the  same  as  in  other 
species  of  Bidens  (sect.  Steppia);  but  a  fair  percentage  of  them 
have  the  shorter  or  secondary  pappus  noticeably  modified  into  an 
annular  or  cupuliform  corona  (not  shown  in  my  illustration),  thus 
strongly  suggesting  the  so-called  Microlecane  material,  here  treated 
as  the  var.  abyssinica.  All  things  considered,  it  seems  that  the  var. 
abyssinica  bears  somewhat  (though  not  entirely)  the  same  relation- 
ship to  B.  setigera  proper  that  Bidens  aristosa  var.  mutica  bears  to 
the  species  B.  aristosa  proper.

The  branches  of  the  type  material  have  internodes  1-1.5  dm. 
long.  Busse's  label  lists  the  plant  as  an  herb  and  gives  its  height  as 
being  up  to  2  meters.  The  interior  involucral  bracts  (like  those  of 
Bidens  praecox)  are  connate  below,  often  even  up  to  the  middle,  thus 
simulating  those  of  the  allied  genus  Thelesperma,  although  the  gen- 
eral habit  in  no  way  suggests  Thelesperma.  The  achenes  are  thick- 
margined  and  suggest  those  of  some  species  of  Coreopsis,  but  the 
occasional  retrorse  barbs  are  foreign  to  that  genus.

Specimens  examined :  Busse  2523  (type,  Berl.). 

Florets,  both  ray  and  disc,  are  lacking  on  the  type.  The  achenes 
had  been  well  formed  even  on  small,  young  heads,  differing  in  this 
respect  from  those  in  ordinary  species  of  Bidens.  Moreover,  the 
achenes  had  produced  at  the  apex  some  sort  of  secondary  growth, 
this  imparting  a  more  or  less  capitate  appearance.  The  growth  in 
question  is  mostly  0.5-0.8  as  wide  as  the  maximum  width  of  the 
achenial  body  and  is  variously  truncate  or  protuberant,  ovoid 
or  subglobose,  sometimes  appearing  faintly  as  if  representing  a  rem- 
nant of  the  disc  floret.  The  general  habit  is  that  of  many  annual 
species  of  Bidens  (unless  as  to  the  submedianly  connate  interior 
involucral  bracts,  which,  however,  are  matched  by  those  in  B. 
phelloptera) ,  to  which  genus  the  species  is  apparently  best  referred 
for  the  present.

2  Bidens  carnea  Heer  is  the  customary  citation,  but  an  early  and  apparently 
original  specimen  by  Regel  (Berl.)  is  accompanied  with  the  inscription  "Bidens

3Baillon,  cited  by  the  Index  Kewensis,  really  gave  (Hist.  PI.  8:  305.  1886) 
the  name  Dahlia  Cervantesii  Lag.  (cf.  DC.  Prodr.  5:  494.  1836).  While  he  treated 
Dahlia  as  a  section  of  Bidens  (op.  cit.  221,  footnote  8;  305,  footnote  8),  he  really 
did  not  directly  make  a  new  combination.

(loc.  cit.),  and  various  other  authorities  give  Lessing  for  the  combination  Verbesina 
crocata,  but  Lessing  (Syn.  Gen.  Comp.  232.  1832)  did  not  make  a  definite  or 
decisive  transfer  from  Bidens  to  Verbesina.    Nor  should  we  overlook  the  fact  that 
in  his  index  (op.  cit.  445)  Lessing  retained  Bidens  crocata  Cav.  but  entirely  omitted 
(op.  cit.  472)  mention  of  any  Verbesina  crocata. 

2  Fide  Ind.  Kew.  1:  300.  1895.    The  type  of  B.  denudata  Turcz.  was  collected 
by  Cuming  (No.  1375) in  the  Province  of  Cagagan,  Luzon,  Philippine  Isls.    I  do 
not  recall  having  seen  it. 

3  Desfontaines  gave  merely  a  name  for  his  plant  and  indicated  it  to  be  a 
perennial.     DeCandolle   (Prodr.   5:   597.   1836)   presented  a  description,   citing 
plants  from  Brazil  by  Commerson  and  by  Lund.    Lund's  one  plant  (Del.)  studied 
is  true  B.  pilosa  L.    The  Prodromus  Herbarium  (Del.)  appears  to  have  no  speci- 
mens by  Commerson.    All  told,  the  Prodromus  specimens  of  "B.  dichotoma  Desf." 
are  five  in  number,  four  being  true  B.  pilosa  L.  and  one  being  B.  pilosa  var.  minor 
(Bl.)  Sherff  (cf.  Chodat,  Bull.  Herb.  Boiss.  2.  2:  394.  1902). 

Desfontaines  later  published  (Cat.  PI.  Hort.  Reg.  Paris  ed.  3.  185. 
1829)  "Bidens  dichotoma  H.  p."  as  a  synonym  for  Blainvillea  rhomboidea  Cass. 
Diet.  Nat.  Sci.  29:  494.  1823.  (Cf.  O.  E.  Schulz,  Bot.  Jahrb.  50,  Suppl.  182. 
1914).  A  small  but  fine  specimen  of  a  "Bidens  dichotoma"  is  preserved  (Petrop.) 
from  material  cultivated  in  1815.  Riedel  sent  it  (whether  the  seed  or  the  plant 
itself  the  label  does  not  specify).  It  is  a  Blainvillea  and  may  well  have  come 
from  the  material  on  which  Desfontaines  founded  his  reduction  of  B.  dichotoma 
to  synonymy  in  1829.

this  handsome  species  of  the  Nyassa  region  were  of  two  kinds, 
differing  generically  on  the  basis  of  the  winged  character  of  the 
achenes.  Further  specimens  have  shown  that  some  material  is 
merely  more  tardy  than  the  rest  in  displaying  achenial  wings.  As 
the  specimens  mature,  their  achenes  become  fairly  well  winged.  Be- 
sides the  type  (W.  Goetze  731,  on  red  laterite,  hilly  plateau,  in  thin

Landii  Sherff,  Bot.  Gaz.  64:  29.  1917.  This  species,  with  its  strongly 
ribbed  leaves,  is  very  close  to  Cosmos  Crithmifolius  H.B.K.,  but 
differs  in  its  yellow  rays  and  slightly  dissimilar  leaf  outline.  In  most 
specimens  the  achenes  are  clearly  erostrate,  but  occasionally  some  of 
the  central  ones  become  highly  elongated  above,  appearing  almost 
distinctly  rostrate  and  thus  exactly  simulating  those  of  such  species 
as  Cosmos  Crithmifolius  and  C.  linearifolius.  This  is  especially 
notable  in  certain  material  collected  by  Barnes  and  Land  (Nos.  164 
and  189,  Field).  In  fact,  the  subrostrate  character  of  the  achenes 
was  known  to  Gray  (cf.  Gray,  loc.  cit.,  "achaeniis  subulatis  .  .  . 
subrostratis").  Yet,  curiously  enough,  he  placed  this  species  in 
Bidens,  while  previously  (Proc.  Amer.  Acad.  19:  16.  1883)  he  had 
determined  as  Cosmos  Seemannii  a  Ghiesbreght  plant,  described 
by  himself  as  having  "essentially  beakless  .  .  .  achenes."  I  have 
examined  the  following  specimens:  Edward  Palmer  315,  Rio  Blanco,

138.  1874;  cf.  Sherff,  Bot.  Gaz.  76:  80.  pi.  8.  1923.  Schultz  Biponti- 
nus, who  reduced  Heterosperma  to  Bidens,  published  without 
description  the  name  Bidens  ( Heterosperma)  rhombifolia  for  a  plant 
collected  by  W.  Lechler,  No.  1576,  in  rubbish-covered  places,  May, 
1854,  Tacna,  Peru.  Later  Grisebach  (loc.  cit.)  transferred  the  species 
to  Heterosperma,  supplying  a  very  scant  description:  "Species  parum 
ab  H.  maritimo  Kth.  foliis  latioribus  (2"  longis,  1"  latis)  recedens." 

The  leaves  of  H.  maritimum  were  described  as  4-4.5  lines  wide; 
those  of  H.  rhombifolium  are  7-9.3  lines  wide,  and  because  of  this 
greater  width  have  a  remarkably  different  aspect.  The  achenes  of 
the  outer,  perfect  (hermaphrodite)  florets  in  H.  maritimum  were 
described  as  obsoletely  tridentate  at  the  apex,  but  the  corresponding 
achenes  of  H.  rhombifolium  are  definitely  biaristate.2  In  1914,  on 

1B.  purpurea  Downing  (Nat.  Great  L.  Region  317.  1922)  is  an  error  for  Bra- 
senia  purpurea  Casp.  (=B.  Schreberi  Gmel.). 

2  It  should  be  remarked,  however, that  in  the  type  plate,  fig. 3,  of  H.  maritimum, 
two  definite  aristae  are  shown  on  the  achene.  No  tridentate  character  is  indicated. 


THE  GENUS  BIDENS  643 

finding  one  of  Lechler's  original  specimens  in  Paris,  I  made  a  draw- 
ing of  it  (Sherff,  Bot.  Gaz.  76:  80,  pi.  8.  1923).  The  leaves  suggested 
strongly  the  possibility  of  the  plant's  being  the  Heterosperma 
ovatifolium  of  Cavanilles,  described  from  "Peru"  in  1822  (Cav.  Descr. 
204.  1802),  and  later  renamed  H.  ovatum  by  Willdenow  (Sp.  PL 
ed.  4.  3:  2129. 1804). 1  Cavanilles'  description  of  the  leaves,  however, 
"Las  hojas  son  aovadas,  de  cinco  a  ocho  lineas  de  largo,"  shows  his 
plant  to  have  been  one  of  the  smaller-leaved  species  native  to 
that  region.  In  the  Paris  specimen  of  H.  rhombifolium  the  principal 
leaves  all  measure  from  9  to  16  lines  long,2  not  5-8  lines  as  given  by 
Cavanilles.  The  plant,  on  comparison  with  Kunth's  plate  in  Hum- 
boldt  and  Bonpland's  Nova  Genera  et  Species  Plantarum  (4:  pi. 
383.  1820),  appears  to  differ  from  H.  maritimum  mainly  in  having 
large,  rhombic-ovate  instead  of  small,  rhombic-lanceolate  leaves. 

Since  the  paucity  of  material  in  the  larger  herbaria  makes  it 
impossible  actually  to  settle  the  separate  identity  of  H.  rhombifolium 
as  distinct  from  H.  maritimum,  attempts  at  synonymizing  the  two 
would  seem  for  the  present  to  be  valueless.

1  In  Cavanilles'  description,  the  name  "Heterosperma  ovatifolia"  [sic]  appears 
not  as  a  binomial  but  merely  as  the  first  two  words  of  a  short  Latin  description, 
followed  by  a  longer  Spanish  description.     Cavanilles'  method  of  presenting  his 
plant  names  in  his  Descripciones  is  not  the  orthodox  post-Linnean  one,  and  only 
by  examination  of  his  treatment  of  the  many  other  plant  names  does  one  find 
surely  that  the  first  two  words  in  each  description  are  the  intended  binomial. 

2  Grisebach's  measurements,  "2*  longis,  1*  latis,"  appear  to  have  been  care- 
lessly taken.

Colla's  rare  work  (Herb.  Pedem.)  describing  this  species  is  inacces- 
sible to  me.  Drs.  Henry  A.  Gleason  and  Elmer  D.  Merrill  very 
kindly  sent  me  copied  portions  of  the  text.  From  the  inscription 
("Bidens  segetum  Mar.")  accompanying  Colla's  type  specimen  and 
from  Colla's  citation  of  the  herbarium  of  Martius  ("14.  B.  segetum 
=  Mart.  hb.")  as  seen  in  these  copies,  though  set  forth  somewhat 
unconventionally,  it  is  evident  that  "Martius  ex  Colla"  should  be 
given  for  the  authorship  of  the  name  B.  segetum.  (Similarly,  B. 
fervida  Hort.  Erf.  ex  Colla  is  correct  for  the  full  citation  of  Colla's 
B.  fervida  on  p.  366.)

Distribution:  Known  only  from  type  locality  in  Nuevo  Leon,

Specimens  examined:  Mueller  2267  (type,  Field). 

The  type  sheet  bears  seven  specimens.  The  dried  capitula  offer 
an  illusory  resemblance  to  those  of  most  South  American  species  of 
Coreopsis,  because  of  the  conspicuous,  dark  interior  involucral  bracts. 
I  am  indebted  to  Mr.  Paul  C.  Standley  of  Field  Museum  for  oppor- 
tunity to  study  this  recently  collected  material  (which  he  had  very 
properly  considered  as  representing  a  new  species),  and  to  prepare 
a  detailed  description  for  insertion  in  this  work. — The  affinities  are 
probably  closest  with  B.  Anthemoides,  B.  andicola,  and  B.  triplinervia 
var.  macrantha.
