co  ... 

MALPIGHIACEAE  Juss. 

Reference:  Niedenzu,  Pflanzenreich  IV.  141.  Hefte  91-94.  1928. 

Lianas  or  sometimes  erect  shrubs,  rarely  arborescent,  always 

Lnmore  or  less  suffruticose,  the  usually  opposite  mostly  petioled  and 

I?  entire  pinnately  nerved  leaves  abundantly  glanduliferous,  the  tri- 

chomes  most  often  brachiate,  bifurcate.    Stipules  usually  present, 

inmost   often   small,   variously   placed.      Inflorescence   terminal   or 

2:  axillary,  simple  or  compound,  rarely  reduced  to  a  single  flower,  the 

^  articulate  peduncles  mostly  bracted  and  bibracteolate.     Flowers 

hermaphrodite,  rarely  apetalous,  the  5  sepals  rarely  connate  at 

v  base,  nearly  always  with  1  (2)  glands,  the  5  petals  commonly  clawed 

r  and  diverse,  often  crenulate  to  ciliate.    Stamens  10  and  all  fertile 

or  ordinarily  in  part  staminodia,  the  filaments  usually  more  or  less 

|   connate,  the  3  styles  usually  free,  obtuse,  capitellate  or  dilated  at 

tip,  sometimes  acute,  the  gynaecium  usually  3-carpellate.    Ovules 

solitary,  pendulous.     Fruit  3(2-4)-parted,  capsular,  drupiform  or 

nuciform,  often  more  or  less,  and  irregularly,  winged  or  samaroid, 

and  simulating  some  Sapindaceae.    Seeds  without  endosperm. 

The  family  is  known  particularly  for  the  highly  narcotic  alkaloid 
furnished  especially  by  Banisteria  caapi,  which  see  below;  omitted 
is  the  related  Amazonian  (Para)  genus  Cabi  Ducke,  Arquivos  Serv. 
Florestal  2,  No.  1:  13.  pi.  1.  1943,  perhaps  also  narcotic  but  unique 
because  the  flowers  are  yellow,  fruits  not  winged. 

My  indebtedness  to  the  kindness  of  Dr.  Jose*  Cuatrecasas  in 
listing  most  of  the  negative  numbers  is  noted  with  thanks.  In  most 
instances  I  did  not  see  the  prints. 

Fruit  more  or  less  winged,  usually  3  samaras  affixed  to  an  elevated 

torus;  plants  infrequently  suberect,  rarely  entirely  upright. 
Samaras  laterally  (and  variously)  alate,  dorsally  merely  carinate 

or  shortly  alate  unless  in  Diplopteris. 
Sepals  (as  bracts)  spathulate  to  oblong  or  oblanceolate,  the 

aestivation  valvate;  styles  curved 4.  Diplopteris. 

Sepal  aestivation  quincuncial;  styles  nearly  straight  unless  in 
Hiraea.  ^

membranous-chartaceous,  smooth  and  lustrous  above,  rarely  more 
or  less  glabrate  beneath,  the  5-6(8)  primary  nerves  prominent  and 
with  the  secondary  reticulate,  the  basal  marginal  glands  2-5;  racemes 
usually  many  in  panicles;  floriferous  pedicels  none  to  2  mm.  long, 
bibracteolate  4-7  mm.  below  the  apex,  pedicels  3-6  mm.  long,  bracts

Apparently  very  much  like  M.  sepium  but  the  pubescence 
typically  velutinous  (however  the  leaves  are  sometimes,  it  seems, 
glabrate  in  Peru),  the  bractlets  provided  with  a  large  gland,  the 
petals  roseate  or  lilac  (sulphureous,  subsp.  thianiha),  and  the  stamens 
rather  unequal  with  often  oblongish  anthers. — The  var.  fusca  Sus- 
senguth,  Repert.  Sp.  Nov.  42:  46.  1937  differs  from  the  type,  accord- 
ing to  its  author,  in  the  brown-velvety  stems  and  petioles,  the  leaves 
to  12  cm.  long,  11  cm.  wide  with  much  looser  pilosity  and  with  2-4 
glands  beneath  about  1  cm.  remote  from  the  margin;  much  more 
aberrant,  and  perhaps  not  correctly  placed  here,  is  Klug  25  with 
strigose  pubescence,  sparse  on  the  leaves  but  with  the  inflorescence 
(including  glands,  flower  color  and  anthers)  of  M.  cordifolia  rather 
than  of  M.  sepium,  to  which  I  at  one  time  referred  it,  with  query; 
it  may  be  designated  M.  cordifolia  var.  peruviana  Macbr.,  var.  nov.,

M.  loretensis  differt  stipulis  vix  1  mm.  longis,  petiolis  ad  12  mm. 
longis  fere  2  mm.  crassis,  foliis  oblongo-ellipticis  apice  breviter 
obtuseque  acuminatis  13  cm.  longis,  5-6.5  cm.  latis,  basi  biglandu- 
losis;  pedunculis  paniculorum  4-5  cm.  longis,  minute  puberulis, 
floriferis  vix  2  mm.  longis,  haud  incrassatis;  pedicellis  circa  15  mm. 
longis;  petalis  suboblongis  4  mm.  longis  tenue  carinatis;  staminibus 
inequalibus  ad  2  mm.  longis. — It  is  for  convenience  that  I  compare 
this  liana  here  (perhaps  new  only  to  Peru),  as  its  relationship  is 
probably  elsewhere;  the  long-peduncled  leafless  axillary  and  terminal 
panicles,  the  latter  about  1.5  dm.  long  and  broad,  are  further  distinc- 
tions, but  without  fruit  its  generic  position — for  that  matter,  of 
course,  its  family  position — can  only  be  surmised.  The  collector 
noted  the  flowers  as  pale  lilac  and  yellow.

M.  nervosa,  the  former  with  violet  or  roseate  flowers,  the  petals 
scarcely  carinate,  lateral  wings  distinct  base  and  apex,  these  in  the 
latter  continuous,  both  species  with  revolute  margined  leaves, 
larger  in  M.  nervosa,  and  both  species  with  narrower  stipules  and 
bracts.

6-8  cm.  wide. — According  to  the  collector  the  Peruvian  plant  was 
a  liana;  apparently  it  is  referable  here  but  the  related  species  seems 
to  be  similar.  The  Williams  specimen,  unfortunately,  like  the  type, 
has  undeveloped  flowers;  therefore  Kostermans'  treatment  of  this 
plant  as  a  variant  marked  merely  by  the  leaves  slightly  sericeous 
beneath,  while  probably  correct,  remains  to  be  proved.  F.M.

3-5  mm.  long  and  nearly  concealed  in  tomentum;  leaves  elliptic  or 
somewhat  ovate,  rounded  at  base,  shortly  apiculate,  to  2  dm.  long, 
more  than  half  as  wide,  nearly  plane,  in  age  smooth  and  more  or

oblanceolate  leaves  acute  at  base,  long-acuminate,  sericeous  beneath, 
the  second  broadly  elliptic  cordate-based  leaves,  obtuse  or  apiculate, 
densely  strigose  beneath,  the  last  subglabrous  oblong-elliptic  apicu- 
late leaves.  Under  an  unpublished  name  by  Morton  after  the  locality 
Putumayo  and  quite  possibly  occurring  within  Peru  is  a  nearly 
glabrous  cordate-based  rotund-leaved  plant,  the  peduncles  without 
the  leafy  bracts  that  characterize  the  other  species;  in  leaf -form  it 
simulates  the  following  Peruvian  collection  so  closely  that  Standley 
gave  it  the  ined.  name.  Because  of  the  uncertainty  of  the  relation- 
ship and  the  constancy  of  the  characters  concerned,  I  designate  this 
liana  with  rust-yellow  flowers  only  as  H.  Spruceana  var.  Mortoniana

—Banisteriopsis  C.  B.  Robins,  ex  Small,  N.  Am.  Fl.  25:  131.  1910 
has  been  proposed  to  supplant  the  Linnaean  name  on  the  ground 
that  the  latter  was  based  on  species  now  assigned  to  other  genera. 
It  would  seem  preferable,  especially  since  there  is  much  preced- 
ence, to  add  the  name  in  the  long-used  sense  to  nomina  conservanda, 
as  proposed  by  Kostermans  in  Med.  Bot.  Mus.  Rijks  Univ.  Utrecht 
25:  7.  1936.  As  the  name  Heteropteris  Kunth,  based  on  the  type 
species  of  Linnets  genus  Banisteria,  belongs  to  the  nomina  con- 
servanda and  Banisteria  L.  has  been  rejected,  Intern.  Rules  ed.  3. 
135.  1935,  it  appears  advisable  to  make  Banisteria  L.,  sens.  Juss. 
a  nomen  conservandum  and  Banisteriopsis  C.  B.  Robins,  ex  Small 
a  nomen  rejiciendum.  The  action  already  taken  need  not  preclude 
this  practical  if  expedient  solution  to  assure  here  generic  stability, 
so  clearly  desirable,  as  observed,  Field  Mus.  Bot.  8:  120.  1930. 
It  is  a  historic  fact  that  law  is  subject  to  change  to  suit  developments. 
The  name  commemorates  John  Banister,  English  missionary  (circa 
1700)  and  author  of  the  first(?)  catalogue  of  the  plants  of  Virginia. 

Banisteria  caapi  and  variants  are  the  source  of  a  narcotic  (cf. 
under  that  species  below).  J.  T.  Baldwin,  Jr.,  Bull.  Torrey  Club  73: 
282-285.  1946,  recorded  the  2w-number  as  20. 

As  suggested  by  J.  T.  Baldwin,  Jr.,  Bull.  Torrey  Club  73:  282- 
285.  1946,  one  of  the  best  short  accounts  of  the  effects  of  the  alkaloid 
which  this  plant  yields  is  by  Louis  Lewin  under  the  title  "Phantastica, 
narcotic  and  stimulating  drugs,"  New  York,  1931,  from  the  German 
second  edition  by  P.  H.  A.  Wirth;  an  extensive  bibliography  is  given 
in  Pflanzenreich,  I.e.  437,  including  a  good  paper  by  Perrot  and 
Raymond-Hamet,  Compt.  Rend.  Acad.  Sci.  Paris  1266.  1927  and 
one  by  Lewin,  I.e.  469.  pi.  186.  1928;  cf.  also  the  observations  of 
G.  Klug  as  reported  by  Morton,  Journ.  Wash.  Acad.  Sci.  21:  487- 
488.  1931.  Baldwin  himself  describes  well  the  extreme  excitation 
of  the  drug  on  the  nervous  system,  the  user  often  being  transported, 
according  to  all  accounts,  into  a  world  of  pleasurable  fantasy. 

The  drug,  variously  known  as  "telepathin,"  "yagein,"  or  "ban- 
isterine,"  is  found  in  a  number  of  related  plants  or  forms,  notably 
B.  quitensis  and  B.  inebrians,  and  Baldwin's  remarks  are  quoted

perience  with  Hevea  I  judge  that  numerous  Amazonian  species 
undergo  introgressive  hybridization  with  resultant  difficulties  for 
herbarium  studies  and  that  many  species  in  that  region  are  . . . 
ecotypes  .  .  .  frequently  accorded  binomial  recognition."  However 
I  would  add  that  we  would  not  make  this  error  so  often  if  we  would 
refrain  from  giving  specific  value  to  characters  obviously  occurring 
in  almost  infinite  variation  within  a  group;  specifically,  here  the 
presence  or  absence  of  glands  is  probably  a  good  example. 

For  convenience  the  key  is  artificial;  the  species  are  not  yet  well- 
placed  or  well-known,  but  the  significant  characters  appear  to  be 
mostly  in  the  styles  and  fruits;  gland  development  anywhere  is 
probably  variable  and  it  is  possible  that  elongate  inflorescences  may 
bear  only  one  or  few  fruits  at  lower  nodes,  giving  herbarium  material 
a  very  different  aspect  in  fruit  than  in  flower. 

Leaves  obviously  pubescent  beneath  even  when  mature;  petals  gla- 
brous, unless  B.  heterostyla.

rather  small  yellow  flowers  borne  on  slender  appressed  strigillose 
pedicels  6-10  mm.  long  or  the  inflorescence  said  sometimes  to  be 
terminal,  leafy;  branches  typically  somewhat  strigose  or  glabrous 
in  age,  more  or  less  lenticellate;  petioles  4-8  mm.  long;  leaves  lanceo- 
late to  elliptic,  acutish  at  the  rounded  base,  more  or  less  acuminate, 
often  to  about  9  cm.  long,  4  cm.  wide,  or  in  Peru  larger,  glabrous

stamens  and  styles  glabrous,  the  latter  nearly  straight  and  subequal; 
petals  glabrous,  a  little  denticulate;  samara  puberulent  especially

that  they  represent  one  entity  which  may  be  a  variant  of  B.  corni-

distinct  and  perhaps  represent  an  undescribed  species:  Seibert  2122

the  wing  about  3.5  cm.  long,  7  mm.  wide  at  base,  16  mm.  below  the

as  follows:  both  with  minute  or  small  stipules,  acuminate  leaves, 
those  of  former  glabrate,  larger  inflorescences,  anterior  style  shorter 
than  2  posterior,  samara  wing  oblong-obovate  or  obliquely  oblong 
and  smaller;  and  further  from  former,  eglandular  petioles,  well- 
peduncled  umbels  and  from  latter,  glandular  leaves.  The  plant 
therefore  seems  to  be  an  intermediate  development  but  the  flowers 
are  unknown  and  the  taxonomic  importance  of  the  characters  noted 
not  proved;  certainly  even  with  material  accumulated  now  there 
appears  to  be  variable  concomitance  in  the  distinctions  stressed. 
On  the  other  hand  there  may  well  be  several  entities,  since  Morton 
saw  60  specimens. 

Morton,  I.e.  pages  487-488,  quoted  Klug's  notes  sent  in  with 
the  type  (Umbria,  Colombia),  describing  the  reported  effects  of  the 
drug  obtained  by  an  all-day  boiling  of  "yag&'  (apparently^,  quitensis,

Liana  or  spreading  shrub  with  many  divaricate  leafless  branches 
forming  intricate  masses;  younger  parts  typically  rusty  sericeous, 
the  indument  more  or  less  persisting  on  the  finally  terete  branches,

species  than  with  B.  elegans,  with  apparently  always  much  larger 
flowers;  cf.  Sandwith,  Journ.  Arnold  Arb.  24:  222.  1943.  However, 
the  species  could  not  be  distinct  on  the  basis  of  presence  or  absence

with  only  6  fertile  stamens  (those  opposite  the  yellow  petals). 
Calyx  with  4  sepals  biglandular.  Petals  dentate  or  fimbriate,  at 
least  the  limb,  4  more  or  less  concave.  Styles  somewhat  unequal, 
all  usually  more  or  less  dilated,  even  foliately,  sometimes  scarcely 
or  not  at  all,  sometimes  only  in  part.  Stipules  none  or  minute. 
Leaves  entire  to  more  or  less  divided,  often  remote,  and  usually 
with  a  pair  of  large  glands  on  the  petioles,  rarely  on  the  midnerve 
beneath.  Flowers  often  in  dichotomously  disposed  umbels,  the 
peduncles  usually  longer  than  the  pedicels. — According  to  Haumann 
Merck,  Rec.  Inst.  Bot.  Bruxelles  9:  21.  1913,  all  stamens  are  fertile 
in  S.  littorale  Juss.,  511  (which  species  is  nearly  S.  tomentosum}', 
Merck's  discovery  caused  Kostermans  to  suggest,  Pulle,  Fl.  Surinam. 
2,  pt.  1:  203.  1936,  that  this  may  be  found  true  for  other  species 
when  observed  living;  according  to  Standley  and  Steyermark, 
Fieldiana;  Bot.  24,  pt.  5:  493.  1946,  only  4  stamens  are  fertile, 
presumably  the  Guatemalan  species.  The  name,  originally  "Stig- 
maphyllon,"  refers,  of  course,  to  the  often  foliose  style  tips  and  was 
"corrected"  by  Niedenzu  to  Stigmatophyllon  and  later  to  Stigmato- 
phyllum. 

Development  of  marginal  glands  and  presence  of  pubescence  on 
anthers  may  not  be  constant  characters,  either  here  or  in  other 
groups.  In  the  entire  family  there  is  probably  hybridization  followed 
by  apomixis. 

The  position  of  S.  Kuhlmannii  in  key  ex  char,  may  not  be  correct. 

Styles  not  foliose,  minutely  if  at  all  dilated,  dissimilar  or  truncate 
or  rounded  apically,  usually  one  (the  anterior)  truncate,  unci- 
nately  produced;  leaves  cordate-rotund-elliptic,  typically  soft 
pubescent  beneath;  samaras  (known)  aceriform. 

Leaves  broadly  cordate,  acute  or  apiculate,  chartaceous;  styles 
subequal S.  primaevum,  S.  bogotense. 

Leaves  elliptic,  obtuse  or  rounded,  rigid-coriaceous;  styles  unequal, 
two  beaked,  one  attenuate  or  acute S.  peruvianum. 

Styles  usually  subsimilar,  two  or  often  all  more  or  less  foliose-dilated; 
leaves  sometimes  loosely  tomentose  beneath. 

Mature  leaves  silvery  beneath  with  a  dense  appressed  indument, 
some  trichomes  long;  marginal  glands  obscure  or  obsolete; 
flowering  branches  simple  to  trifurcate,  the  umbels  congested.

caducous,  broadly  rounded  to  0.5  mm.  long;  petioles  3-6  cm.  long, 
conspicuously  biglandular  at  tip;  leaves  cordate,  more  or  less  long- 
acuminate,  to  15  cm.  long  and  11  cm.  wide,  the  more  or  less  repand 
margins  with  sessile  or  ciliiform  glands,  membranous,  early  sub- 
sericeous,  in  age  glabrate,  except  along  the  little  prominent  nerves; 
corymbs  10-20-flowered,  dichotomously  terminating  axillary 
branches,  the  compressed  peduncles  4-10  mm.  long,  pedicels  3-7 (-15)

mm.  long,  bracts  glandular  and  bractlets  1-1.5  mm.  long;  flowers 
2-3  cm.  broad;  sepals  rounded  ovate;  petals  yellow  without,  margin- 
ally dotted,  the  ciliate  or  fimbriate  orbicular  limb  with  claw  2-3  (-4) 
mm.  long;  anthers  glabrous  (or,  as  here  interpreted,  a  little  pilose), 
the  connectives,  especially  the  sterile,  very  thick;  styles  subhispid 
at  base,  the  tips  usually  foliolate,  that  of  the  anterior  spreading, 
those  of  the  posterior  pendulous  and  ordinarily  minutely  apiculate 
beneath;  samara  glabrate,  the  suberect  wing  to  2. 5 (-5)  cm.  long, 
nearly  12  mm.  wide,  the  straight  anterior  edge  dilated-appendaged 
at  base,  the  nut  laterally  crested  transversely,  the  ventral  areole 
obovate.— According  to  the  monographer,  I.e.  456,  the  Linnaean 
plant  is  either  this  species  or  S.  Lalandianum  Juss.,  486,  Brazil  and 
Colombia,  the  leaves  somewhat  sericeous  beneath,  eglandular;  there 
are  several  more  closely  allied  species  to  be  expected.  But  this  and 
S.  tiliaefolium  may  be  variable  and  thus  include  more  forms.  I

the  leaves  usually  about  10  cm.  long,  8  cm.  wide,  seem  to  be  more

Shrubby  liana,  the  complanate  branchlets,  cylindric  branches  and 
leaves  beneath  densely  clothed  with  a  short,  often  reddish  tomen- 
tosity;  stipules  minute,  coriaceous,  deciduous;  petioles  stout,  bi-

ovate,  rounded  at  base  and  apex  or  there  emarginate  or  apiculate, 
sometimes  16  cm.  long,  13  cm.  wide;  coriaceous  or  firm,  typically 
punctate-scabrous  above  (apparently  often  smooth  in  Peru  as  else- 
where); inflorescence  bracts  linear,  to  1  cm.  long,  biglandular; 
umbels  many-flowered,  peduncles  4-10  mm.  long,  pedicels  4-8  mm.

to  4.5  cm.  long. — Description  as  usual  after  Niedenzu  but  thus  in- 
terpreted it  would  be  impossible  to  find  it  from  his  key  since  he 
lists  it  under  the  character  "anthers  glabrous";  all  told,  except  for

and  curiously  enough,  since  the  type  (from  thick  Igapo  woods,

289.  1840,  at  least  as  to  Peru. 

Scandent  shrub,  the  compressed  branchlets  tomentose,  the  smooth 
glabrate  branches  brown,  3  mm.  thick;  petioles  short  or  long  (to 
8  cm.  long),  the  two  apical  glands  sessile,  patelliform;  leaves  sub- 
rotund-cordate  or  the  smaller  ovate,  basally  obtuse  or  acute,  shortly 
acuminate  and  mucronate,  4-9(12)  cm.  long,  3-7(14)  cm.  wide, 
revolutely  repand,  (or  in  Peru  plane)  and  the  nerves — these  promi- 
nent beneath — terminating  in  short  glands,  membranous  or  charta- 
ceous,  glabrate  above  except  the  nerves,  more  or  less  tomentose  or 
sericeous  beneath;  peduncles  3-5  mm.  long,  the  pedicels  2-4  mm. 
long;  bracts  oblong,  1.5-2  mm.  long,  the  rotund-ovate  bractlets  1 
mm.  long;  flowers  16-18  mm.  broad,  the  sepals  broadly  ovate,  the 
yellow  petals  pilose  without  or  below,  denticulate,  orbicular  from  a 
cuneate  base;  filaments  in  part  (unknown  in  type)  as  styles  S-curved 
(curved  or  nearly  straight  in  Peru  and  subequal),  the  posterior  longer 
than  the  anterior,  the  styles  sinuately  foliolate;  anthers  often  a  little 
pilose  in  Peru;  samara  nut  acutely  auricled,  rugose-cristate  or 
smooth;  the  wing  2.5  cm.  long  or  longer,  the  lower  margin  slightly 
repand-denticulate. — Name  "corrected"  by  some  to  "tiliifolium"; 
the  type  from  Colombia  was  in  fruit,  the  species  floral  character 
therefore  by  later  authors.  None  of  the  Peruvian  material  seems  to 
be  entirely  in  conformity  but,  as  the  experienced  and  intelligent 
Grisebach  observed,  species  may  well  be  variable  and  here  especially 
as  regards  marginal  leaf-glands  and  degree  of  nutlet  crests;  anyway 
it  is  one  of  the  earliest  names  in  a  group  of  poorly  understood  or  not 
clearly  defined  entities.  As  to  the  name  itself,  some  authors  are 
using  S.  Humboldtianum  (DC.)  Juss.  because  of  the  existence  of 
the  name  Banisteria  tiliaefolium  Vent,  1803.  There  is,  however,  no

Genus  and  family  named  for  the  first  celebrated  anatomist,  who 
was  also  a  physician  and  philosopher,  Marcello  Malpighi.  He  was

M.  coccigera  L.  of  the  West  Indies,  where  known  as  Singapore 
Holly,  is  probably  cultivated;  it  has  1-2  pink  flowers  and  globose 
red  fruits.  The  even  better  known  Barbados  Cherry  or  Escobillo 
with  3-8  pink  flowers  and  fruits  with  thin  flesh  is  M.  glabra  L., 
which  may  be  Ruiz  and  Pavon's  "ciruela  de  Fraile"  from  Chancay 
that  had  "fruit  with  very  sweet  and  cloying  taste,  its  seeds  tasting 
like  almonds  but  very  nauseating.  In  order  to  mature  it  must  be 
kept  in  straw,  bran  or  other  matter  for  several  days  when  it  ripens 
and  becomes,  from  the  slight  fermentation,  as  soft  as  butter,  sweet 
with  red  flesh."

Small  trees  or  erect  shrubs,  at  least  the  younger  parts  more  or 
less  pubescent,  with  entire  leaves  and  axillary,  mostly  many-flowered 
and  elongate  racemes  of  small  flowers,  the  bractlets  usually  with 
l(-2)  conspicuous  gland.  Stipules  small,  linear-lanceolate,  acute, 
interpetiolar.  Calyx  glands  10,  in  part  more  or  less  connate,  the 
sepals  not  enlarged.  Petals  and  stamens  glabrous,  the  filaments 
more  or  less  joined  at  base  as  also  the  styles  or  these  free,  obliquely 
obtuse  or  capitellate,  the  ovary  glabrous  or  sericeous.  Pyrenes 
2  or  3,  smooth. — The  name  was  derived  from  the  Arabic  "bunchos," 
meaning  coffee,  which  the  pyrenes  simulate  and  which  are  said  to 
serve  as  a  substitute.  Species  (as  accepted)  very  difficult  to  dis- 
tinguish, the  key  only  suggestive.  With  the  approach  so  usual  to 
some  monographers,  key  characters  are  often  "destroyed"  in  varietal 
distinctions.  While  characters  of  styles  and  ovary  are  not  always 
constant  they  are  usually  and  thus  convenient  as  any  for  separating 
herbarium  material  as  determined. 

Styles  soon  free  or  partly  so;  anther  connective,  except  B.  media, 

elongate;  leaves  in  general  oblong-,  elliptic-,  or  ovate-lanceolate.

the  Weberbauer  specimen  and  the  Raimondi  one,  both  from  Puno, 
are  really  the  same,  in  spite  of  the  fact  that  both  were  determined

sericeous  tips  of  the  new  branchlets;  stipules  ovate,  connate,  1.5  mm. 
long  or  the  upper  subulate  and  longer,  the  inner  trichomes  often

bracts  and  bractlets  typically  scarcely  1  mm.  long;  flowers  12-15 
mm.  wide,  the  ovate  sepals  with  oblanceolate  glands,  the  limb  of

with  yellow  filaments;  anthers  linear,  the  hirsutulous  cells  nearly 
bicornute  with  setae  longer  than  the  thick  connective;  ovary  glabrous 
unless  for  a  few  trichomes. — To  25  meters  high,  the  bark  with  coarse 
shallow  fissures  (Williams).  The  Peruvian  material  is  not  typical 
but  too  many  species  have  been  proposed  on  differences  doubtfully 
constant,  as  variations  in  bracts,  anther  appendages  and  connec-

there  puberulent-pilose;  leaves  8-16  cm.  long,  3.5-8.5  cm.  wide,  pale 
brown  beneath  and  at  least  in  the  areoles  puberulent;  peduncles 
2-3.5  cm.  long,  pedicels  about  1  cm.  long;  bracts  inclined  to  recurve,

Typically  the  indument  is  puberulent,  the  stipules  are  4-6  mm.  long,

pubescence,  stipules  8-10  mm.  long,  anthers  2-3  mm.  long.  It 
seems  probable  thatB.  brachystachia  DC.  Prodr.  1:  581. 1824  (written 
B.  brachystachys  and  B.  brachystachya  by  Niedenzu),  is  an  earlier 
name  for  this  species,  the  description  as  amplified  by  Jussieu  not 
disclosing  any  significant  difference.  The  monographer  observed 
that  it  is  transitional  to  the  genus  Alcoceratothrix  Ndz.,  since  like 
that  the  leaves  are  areolate,  stipules  long;  Sandwith,  Kew  Bull.  311.

long;  bracts  and  bractlets  subequal,  sepals  often  eglandular. — B. 
lancifolia  Juss.,  703,  of  Brazil  has  leaves  rather  oblanceolate  or  some- 
what obovate,  ashy  or  metallic  lustrous  beneath,  the  bracts  about 
twice  as  long  as  the  bractlets. 

The  type,  from  Brazil,  is  probably,  sens,  lat.,  a  part  of  B.  chryso- 
phylla  and  neither  form,  perhaps,  is  a  stabilized  entity.

W.  H.  Wagner,  Jr.,  graduate  student,  University  of  California, 
kindly  dissected  one  of  the  two  available  flowers,  preserving  it  in  a 
slide  which,  with  his  sketches,  is  filed  with  the  type  and  I  record 
my  appreciation  of  his  careful  work  so  generously  contributed.  The 
plant  simulates  B.  stipulacea  Juss.,  762  (Alcoceratothrix  Ndz.),  in 
its  subsessile  leaves  and  conspicuous  stipules  (only  one  is  on  the  tip 
of  the  flowering  branch  that  constitutes  the  type).  However,  no 
trichomes  have  been  found  other  than  the  subsessile,  simply  biforked 
ones  characteristic  of  all  species  except  B.  stipulacea.  Sandwith's 
suggestion,  Kew  Bull.  311.  1935,  for  the  retention  of  the  latter  in 
Byrsonima  seems  to  be  correct  in  view  of  the  discovery  of  this 
apparently  intermediate  species. 

The  rather  recent  death  of  the  collector  of  this  interesting  plant 
is  recorded  with  regret.  Mr.  G.  Klug  was  an  enthusiastic  collector 
and  able  observer  for  many  years  near  Iquitos;  appropriately  his 
name  was  given  to  a  number  of  species  discovered  by  him  and,  re- 
markably, in  a  region  relatively  well  known.

Trees  with  large  chartaceous  or  coriaceous  leaves,  the  flowers 
borne  in  (l-)3  racemes  at  the  tips  of  the  crowded  branchlets.  Bracts 
and  bractlets  short,  broad  and  somewhat  amplexicaul,  each  usually 
with  a  large  orbicular  gland.  Petals  5,  four  with  long  slender  strongly 
recurved  claws  and  cochleate  incurved  blades,  the  fifth  spreading, 
less  recurved,  the  blade  smaller,  nearly  plane  and  with  stoutly  stiped 
glands  all  around  the  margin.  Stamens  glabrous,  the  filaments 
dilated  below  where  coalescent,  the  connectives  enlarged.  Styles  3, 
incurved  before  anthesis,  apically  uncinate,  only  one  seed  developing 
in  the  somewhat  acute  nut. — A  similar  Amazonian  shrub  or  tree 
has  been  named  Glandonia  macrocarpa  (Benth.)  Griseb.,  767,  charac- 
terized by  rigid  linear  caducous  stipules,  sericeous  filaments,  fifth 
petal  glandular  toward  base,  nut  cylindric,  apically  umbilicate.

Branchlet  tips  rusty  sericeous  but  soon  glabrate  as  the  stout 
petioles,  these  1-2  cm.  long,  and  the  coriaceous  persisting  intra- 
petioler  stipules,  these  sometimes  glabrate,  5-10  mm.  long;  leaves 
ovate  or  oval,  rounded  or  obtuse  at  both  ends,  usually  dull  and 
nearly  glabrous  both  sides  or  in  one  form  regularly  but  sparsely 
pruinose-pulverulent  beneath,  always  coriaceous  and  with  the  6-10 
or  more  lateral  nerves  often  so  prominent  beneath  that  they  are 
ribiform;  peduncles  1-3  dm.  long,  the  glabrate  to  sericeous  racemes 
mostly  in  3's  and  ordinarily  about  a  dm.  long;  pedicels  6-13  mm. 
long  with  very  broad-based  acuminate  bracts  and  bractlets;  flowers 
rose-colored,  over  a  cm.  wide,  4  petals  concave,  the  fifth  plane  and 
coarsely  gland-margined;  anthers  2-3  mm.  long  with  broader  ob- 
liquely oblong  connective  exceeding  the  cells  by  about  1  mm.; 
nut  opaque,  pyramidal  or  conoid,  finally  minutely  trivalvate  at  tip, 
about  1  cm.  long,  nearly  as  broad  at  base. — A  number  of  variations, 
particularly  in  shape  of  leaves,  length  of  petioles  (1-1.5  cm.)  and 
even  shape  of  nuts  (as  var.  sphaerocarpa  Ndz.),  have  been  named.

Glabrous  or  more  or  less  pubescent  or  tomentulose,  sometimes 
resinous  with  scattered,  opposite  or  whorled,  often  beautifully  veined 
leaves  and  usually  showy  fragrant  yellow  flowers  borne  in  compound 
(rarely  simple)  elongate  racemes  or  panicles  ordinarily  terminal,  the 
pedicel  bracts  caducous.  Stipules  deciduous,  subulate.  Sepals 
connate  at  base,  the  posterior  much  the  largest,  often  spurred.  Petals 
usually  3,  linear  or  spathulate,  anterior  mostly  larger  than  the  others. 
Fertile  stamen  with  subulate  or  filiform  filament  at  most  half  as

and  Vochy,  this  the  native  name  used  by  Aublet;  Stafleu,  I.e.  400, 
has  decided,  apparently  with  good  reason,  that  Vochysia  is  the  form 
conserved. 

My  indebtedness  to  Stafleu's  work  is  acknowledged,  with  especial 
appreciation  for  his  intelligent  approach  and  lucid  presentation  with 
inadequate  material  and  information;  see  his  general  remarks,  I.e. 
401  et  seq.  When  I  have  not  entirely  followed  his  taxonomy  I  have 
been  prompted  by  the  desire  to  simplify  it  if  possible,  in  conformity 
with  the  scope  of  this  floristic  compilation. 

According  to  Record  and  Hess,  Timbers  of  the  New  World,  1943, 
a  few  species  are  promising  for  lumber  but  apparently  the  wood  is 
usually  inferior.  Some  Brazilian  species  yield  a  resin,  like  gum 
arabic,  said  to  be  of  excellent  quality;  cf.  Silveira,  Arch.  Mus.  Rio

POLYGALACEAE  Lindl. 

Herbaceous  or  ligneous,  sometimes  scandent,  with  variously 
disposed  leaves,  the  stipules  glanduliform  or  lacking.  Flowers 
perfect,  often  irregular,  each  usually  with  a  bract  and  two  bractlets. 
Sepals  5,  partly  or  entirely  free,  or  the  two  lower  united,  the  inner 
two  usually  much  larger  and  petaloid,  as  wings.  Petals  3,  rarely  5, 
free  or  united,  hypogynous,  the  anterior  boat-shaped,  as  keel,  and 
often  crested,  the  two  upper  frequently  galeate,  usually  united 
below  to  the  staminal  sheath  and  often  also  to  the  keel.  Stamens 
8 (or  3-7),  the  filaments  ordinarily  united  into  a  split  sheath;  anthers 
with  subterminal  pores.  Disk  present,  glanduliform  or  wanting.

Glabrous;  stems  erect,  slender,  2-6  dm.  high,  simple,  or  above 
with  a  few  very  slender  elongate  branches  terminating  in  racemes 
2-9  cm.  long  or  longer,  the  nearly  filiform  pedicels  (-1  mm.  long)

often  roseate,  1.5-2  mm.  long,  the  subequal  outer  sepals  ovate- 
lanceolate,  wings  elliptic,  3-nerved  or  nearly  1-nerved,  little  longer 
than  the  crested  keel  (2  mm.  long);  upper  petal  lanceolate,  subretuse; 
anthers  subsessile  on  the  tube;  capsule  oblong-elliptic,  with  a  row 
of  glands  each  side  of  septum,  subequaling  wings;  seeds  oblong- 
elliptic;  aril  minute,  bilobed,  appressed,  obtuse  both  ends,  slightly 
puberulent,  1.2  mm.  long  (Blake). — Svenson,  Amer.  Journ.  Bot.  33: 
458.  1946,  has  noted  that  Chodat's  illustration  of  the  seed  of  P. 
alopecurus  matches  that  which  he  shows  for  the  species  of  St.  Hilaire, 
both  with  aril  only  one-tenth  length  of  seed,  the  author's  key 
character  for  his  species,  "aril  one-half  length  of  seed"  evidently 
an  error.  Since  Svenson  found  seeds  1.5  mm.  long  in  specimen  from 
Colombia  (det.  Blake,  P.  leptocaulis)  and  seeds  averaging  1.1  mm. 
long  in  P.  alopecurus,  from  general  type  region  (Chanduy),  it  is 
probable,  as  he  states,  that  the  latter  is  no  more  than  a  small-seeded 
variation  of  P.  leptocaulis  which  in  turn  seems  not  clearly  separable 
from  the  Brazilian  plant.  According  to  Wm.  Hunter  (cf.  Svenson) 
this  "purple  flowered  grass"  appears  only  in  occasional  years.  Illus-

Scandent  shrubs  with  the  characters  in  general  of  the  other 
groups  but  sepals  usually  deciduous  and  with  compressed  1-celled 
ovary  gibbous  above  and  1-ovuled  with  lateral  curved  style  and 
simple  stigma,  and,  most  distinctively,  a  dry  indehiscent  rugose  or 
hirsute  fruit  with  a  large  erect  wing  and  1  estrophiolate  naked  seed.— 
While  Oort's  work,  except  for  S.  volubilis,  is  not  descriptive  it  is 
highly  valuable  in  its  interpretation  of  earlier  species;  acknowledg- 
ment of  my  indebtedness  is  made  with  pleasure.

or  axillary,  rarely  aggregate,  the  peduncle  usually  bracted  above. 
Sepals  5,  the  3  outer  free,  herbaceous  or  the  2  lower  united,  the  2 
inner  (wings)  petaloid,  usually  much  larger  and  more  or  less  concave. 
Petals  3,  the  lower  (keel)  carinate,  the  2  upper  ligulate,  usually 
elongate,  united  below  to  the  staminal  sheath.  Stamens  8  or  6, 
the  filaments  united  nearly  to  apex  into  a  sheath  or  split  on  the  upper 
side;  anthers  1-  to  2-celled,  sometimes  emarginate  or  mucronate. 
Ovary  rarely  2-celled;  style  geniculate,  exceptionally  rather  straight, 
sometimes  auricled;  stigma  with  2  dissimilar  lobes,  the  lower  more 
or  less  acute,  the  upper  papillose  with  one  or  two  tubercles.  Disk 
ordinarily  reduced  to  a  gland  at  base  of  ovary.  Fruit  a  drupe  with 
thin  fleshy  coat,  rugose,  sometimes  samaroid,  narrowly  and  sub- 
equally  winged. 

With  the  author's  approval  I  have  compiled  this  for  him;  the 
wording  is  thus,  for  convenience  and  in  the  interest  of  uniformity, 
often  mine  and  of  course  I  take  responsibility  for  omissions  and 
mistakes.  I  take  great  pleasure  in  having  Dr.  Ferreyra  as  a  con- 
tributor and  hope  that  Peruvian  botanists  will  have  the  opportunity 
to  take  an  ever  greater  part  in  the  study  of  their  economically  im- 
portant but  little  known  flora.

Slender  trunked  trees  or  shrubs  (usually),  sometimes  clambering, 
with  alternate  short-petioled  entire  leaves,  small  (rarely  fimbriate) 
deciduous  stipules  and  rather  inconspicuous  flowers,  often  congested 
in  axillary  panicles,  or  borne  together  on  the  petioles,  or  on  the  leaf 
blades,  polygamous  or  dioecious,  rarely  hermaphrodite,  often  a  little 
irregular.  Sepals  and  petals  5(4),  the  former  usually  equal,  sometimes 
basally  united,  the  latter  free  or  more  or  less  coherent  and  ordinarily 
rounded  or  in  varying  degrees  parted  apically.  Disk  often  with 
glands  or  appendages  at  base  of  petals  with  which  the  stamens  are 
sometimes  more  or  less  joined,  these  usually  5(3),  the  anthers  with 
broadened  connective.  Ovary  2-3-celled,  styles  2-3  rarely  united 
nearly  to  tip,  the  stigmas  mostly  capitulate;  ovules  2,  pendent. 
Fruits  often  obliquely  ovoid  and  rather  flattened,  commonly  pubes- 
cent and  1 -seeded. — Thought  to  be  closely  allied  to  Euphorbiaceae 
with  which  Baillon  united  it.  Some  species,  notably  in  Dichapetalum, 
contain  a  very  poisonous  alkaloid.

margin;  petioles  5-10  mm.  long;  flowers  glomerulate  at  or  below 
the  tip  of  the  petioles;  pedicels  scarcely  1  mm.  long;  corolla  lanate 
within,  the  clawed  subequal  lobes  twice  as  long  as  the  very  unequal 
calyx  segments;  fertile  stamens  unequal;  anther  connective  sub- 
glandular;  staminodia  two,  entire  or  bifid;  disk  subentire  or  emargi- 
nate;  ovary  3-celled,  the  three  styles  pilose;  fruit  subglobose  or 
obliquely  ovoid,  lutescent  ferrugineous,  1.5  cm.  long,  1  cm.  thick.— 
Bentham  separated  his  species  on  the  basis  of  outer  broader  lanceo- 
late corolla  lobes,  the  flowers  in  size  and  shape  resembling  those  of 
T.  ciliata  Gardner,  Hook.  Icon.  5:  pi.  466  (T.  amazonica  var.  ciliata 
[Gardner]  Baill.,  375),  the  younger,  densely  ciliate  leaves  with  upper 
midnerve  tomentose,  and  somewhat  pubescent  beneath.  Apparently 
the  Bentham  plant  was  overlooked  by  Baillon  in  his  account  of  the 
Brazilian  species  in  Martius'  Flora.

Apparently  a  very  distinct  Tapura,  the  cream-colored  flowers  borne 
well  above  the  base  of  the  phylloidiform  leaves;  the  type  was  a  2- 
meter  tree. 

In  naming  this  for  my  well-known  friend  Julian  Steyermark 
meritorious  recognition  is  given  of  his  generous  co-operation  in  the 
preparation  of  this  work,  especially  by  his  careful  selection  of  her- 
barium materials  for  my  study.

Glabrous  except  for  the  sparsely  pilose  branchlet  tips,  midrierve 
of  the  thin  herbaceous  leaves  beneath  and  the  densely  tomentose 
sepals,  these  in  life  white  or  yellowish,  unequal,  oblong,  obtuse,  to 
5  mm.  long;  petioles  3-5  mm.  long;  leaves  narrowly  oblong,  sub- 
abruptly  cuspidate,  with  acumen  1.5-2  cm.  long,  base  a  little  oblique, 
10-13  cm.  long,  3-4.5  cm.  wide,  with  7-9  slender  lateral  nerves; 
flowers  white,  fragrant,  few  in  axillary  capitate  cymes  on  the  petioles, 
the  two  subconcave  larger  petals  to  8  mm.  long;  fertile  stamens 
two  or  three;  style  1  cm.  long,  pilose  to  tip. — Like  T.  peruviana  but 
smaller  in  all  parts  except  the  yellow  calyx  and  snow-white  flowers 
(Krause);  and  distinctions  of  doubtful  value;  the  type  from  a  5- 
meter  tree  densely  branched  at  2  meters,  the  trunk  1  dm.  in  diameter. 
Flowers  cream-colored,  the  fruit  said  to  be  yellow  and  edible  (Mexia).

Branchlets  as  the  2-4  mm.  long  petioles  sparsely  pilose;  leaves 
thin,  glabrous  except  for  a  few  trichomes  beneath,  nearly  oblong  or 
oblanceolate-oblong,  longish  cuspidate-acuminate,  10-13  cm.  long, 
3-4  cm.  wide,  the  5-6  lateral  nerves  little  impressed  above  but 
prominent  beneath;  flowers  in  axillary  petiolar  cymes  (on  the  blade 
above  the  petiole  tip),  yellow  or  orange  in  life;  sepals  ovate-oblong 
or  oblong,  obtuse,  tomentose,  to  5  mm.  long;  larger  concave  petals 
shortly  bifid,  1.2  cm.  long,  smaller  oblong;  style  glabrate  above. — 
Type  from  a  tree  10  meters  high.  The  extraordinarily  large  flowers 
as  well  as  the  shape  of  the  leaves  make  the  species  distinctive 
(Krause).  F.M.  Neg.  13146.

4.    GONYPETALUM  Ule 

Characters  of  the  family  in  general.  Flowers  irregular,  including 
the  basally  united  sepals,  the  two  larger  long-clawed  petals  attached 
at  base  with  fertile  stamens,  then  twice  geniculate  and  terminating 
in  a  bilobed  tip,  the  three  smaller  completely  free,  unparted  but 
also  geniculate.  Filaments  of  the  three  fertile  stamens  pubescent 
at  base;  anthers  cordate.  Disk  with  two  glands  at  base  of  sterile 
filaments.  Style  filiform,  shortly  3-parted. 

Leaves  minutely  and  sparsely  pubescent  beneath;  flower  clusters 

sessile. 

Leaves  acutely  acuminate,  mostly  about  8  cm.  long,  membranous. 

G.  acreanum. 
Leaves  obtuse  or  very  shortly  and  obtusely  acuminate,  mostly 

about  5  cm.  long,  coriaceous G.  Tessmannii. 

Leaves  deciduously  but  densely  pubescent  beneath;  flower  clusters 
somewhat  peduncled G.  juruanum. 

Gonypetalum  acreanum  Ule,  Notizbl.  Bot.  Gart.  Berlin  6: 
312.  1915. 

Branches  slender,  terete;  petioles  6-12  mm.  long;  leaves  obovate- 
oblong,  slenderly  long-acuminate,  7-10  cm.  long,  2.5-3.5  cm.  wide, 
membranous,  revolute-margined,  glabrous  above,  sparsely  pubescent 
beneath,  mostly  on  the  slender  nerves;  flowers  20-30,  subsessile  in 
crowded  cymes,  densely  lanuginose;  petals  ochroleucous  (or  white), 
the  two  larger  nearly  5  mm.  long,  biparted  into  two  obovate  concave 
lobes,  the  three  smaller  entire;  stamens  5.5  mm.  long,  the  three  fertile 
high  connate  with  the  larger  petals,  the  two  sterile  little  adnate  with 
the  small  petals;  filaments  as  style  and  bases  of  petals  very  arachnoid- 
lanate;  disk  lobes  two,  fleshy. — Author  found  variation  in  nature  of 
flowers  suggesting  Tapura.  Type  from  trees  15-30  meters  high  in 
terra  firma.  G.  juruanum  Ule  is  similar,  but  the  larger  (14-16  cm.) 
leaves  tapering  more  gradually  to  tip  and  densely  pubescent  beneath. 
G.  lanceolatum  Ducke,  Archiv.  Jard.  Bot.  Rio  Jan.  6:  43.  1933,  of

Gonypetalum  Tessmannii  K.  Krause,  Notizbl.  Bot.  Gart. 
Berlin  11:  137.  1931. 

Stout  branchlets  tomentulose;  petioles  6-9  mm.  long;  leaves 
oblong  or  obovate-oblong,  5-6.5  cm.  long,  22-26  mm.  wide,  rather 
broadly  and  obtusely  acuminate,  rigid-coriaceous,  glabrous  and 
lustrous  above,  appressed  pilose  on  midnerve  beneath,  otherwise 
glabrous;  lateral  nerves  7-9,  impressed  above,  prominent  beneath; 
flowers  in  capitate  axillary  cymes  at  tip  of  petiole;  sepals  unequal, 
ovate-oblong,  2.5  mm.  long,  puberulent-tomentulose  as  the  shorter 
pedicels;  petals  yellow,  unequal,  larger  2.4-5  mm.  long,  long-clawed, 
twice  geniculate,  biparted,  the  three  smaller  undivided;  fertile 
stamens  three,  6  mm.  long,  anthers  lanuginose;  ovary  tomentose. — 
Differs  from  both  described  species  by  the  broadened  leaf-tip 
(Krause),  but  is  doubtfully  more  than  a  variant  of  G.  acreanum. 
The  type  from  a  25-meter  tree  with  trunk  diameter  of  1.3  meters, 
densely  branching  at  15  meters.  F.M.  Neg.  13152.
