BIGNONIACEAE  [Juss.]  Persoon.    Bignonia  or 
Trumpet  Vine  Family 

References:  Bureau  &  K.  Schumann  in  Mart.  Fl.  Bras.  8,  pt.  2. 
1896;  Sandwith,  Fl.  Suriname  4,  pt.  2:  1-86.  1938. 

Erect  or  scandent,  rarely  herbs,  ordinarily  ligneous,  the  usually 
lenticellate  branches  often  closely  glandular  in  vicinity  of  nodes,  the 
leaves  often  immersed  glandular,  these  commonly  opposite  or  nearly, 
rarely  spiralled,  simple  or  frequently  and  variously  compound,  but 
mostly  conjugate  or  ternate.  Axillary  buds  (outer  scales)  if  obvious 
stipuliform,  small  or  more  or  less  foliaceous,  sometimes  seriate.  In- 
florescence terminal  or /and  axillary,  a  raceme  or  thyrse,  somewhat 
compound  or  now  and  then  1-few-flowered.  Flowers  hermaphrodite, 
little  or  rarely  distinctly  zygomorphic;  calyx  truncate,  denticulate  to 
lobed  or  spathe-like,  then  early  or  tardily  split;  corolla  in  general 
funnelform,  tube  more  or  less  defined,  lobes  rarely  valvate.  Fertile 

,  stamens  4,  didymous,  the  staminode  sometimes  reduced  or  obsolete, 
the  anther  cells  parallel  or  divaricate,  one  rarely  imperfect.  Disk  if 
present  annulate,  cupulate  or  solid.  Ovary  bicelled  or  1-celled,  the 
few  to  usually  many  ovules  on  2  (rarely  1)  commonly  axial  placentae. 

v  Fruit  if  capsular  with  2  valves  either  parallel  or  at  right  angles  to  the 
septum,  sometimes  baccate  and  indehiscent.  Seeds  exalbuminous, 
clearly  or  little  compressed,  thinly  or  stoutly  alate,  infrequently  not 
alate,  sometimes  marginate,  and  included  in  a  pulp. 

For  convenience  the  bud  scales  that,  developed,  simulate  stipules 
may  be  so  termed  hereafter  to  avoid  the  accurate  but  clumsy  name 
"pseudo-stipules;"  anyone  wishing  to  emphasize  the  obvious  may 
read  "bud  scales." 

It  is  fortunate  that  the  studies  of  Sandwith — see,  especially,  be- 
sides Fl.  Suriname,  I.e.,  Recueil  Trav.  Bot.  Neerl.  34:  205-232.  1937, 
i.e.  Meded.  Bot.  Mus.  Rijksuniv.  Utrecht,  and  Kew  Bulletin  1932- 
1959 — have  permitted  the  preparation  of  the  following  synopsis  with 
many  problems  of  nomenclature  and  classification  clarified;  it  is  un- 
fortunate that  he  himself  declined  to  present  an  account.  However, 
except  for  my  own  phrasing,  his  published  work  has  been  copied  or 
at  least  his  judgments.  I  am  indebted  also  to  the  considerate  pre-

sentation  of  the  family  as  it  occurs  in  the  Mayan  area  by  Russell  J. 
Seibert,  Carnegie  Inst.  Wash.  Misc.  pap.,  no.  21:  377-434.  1940, 
and  for  his  paper  on  glands,  Ann.  Mo.  Bot.  Gard.  35:  123-136. 
1937.  A  morphological  study  of  the  various  types  of  staminodia  was 
made  by  Josef  Rohrhofer  (under  Wettstein),  Oesterr.  Bot.  Zeitschr. 
80:  1-30.  1931,  with  many  drawings  and  a  bibliography;  he  found 
the  sterile  stamen  similar  in  genera  considered  related.  Significant 
studies  of  the  pollen  grains  were  done  by  Urban  (Berichte  Deutsch. 
Gesellsch.  34.  1916),  by  Pichon  (Bull.  Soc.  Bot.  France  92:  1946), 
by  J.  C.  Gomes,  Jr.  (Rodrigu<§sia  32  (20):  112-118.  1957),  and  by 
others,  as  cited.  Pichon,  I.e.  by  proposing  a  number  of  genera 
based  especially  on  character  of  pollen  has  pointed  up  the  contra- 
dictory evidence  or  interpretation  of  relationships  within  the  family. 

Especially  important  in  relation  to  the  taxonomy  for  this  group 
may  be  the  anatomy;  in  realization  of  this,  Bureau  &  Schumann 
made,  I.e.  6-10,  an  anatomical  key  to  the  Brazilian  genera  which 
Dr.  S.  Carlquist  of  the  Rancho  Santa  Ana  Botanic  Garden  plans 
to  translate  and  devise  to  include  the  Peruvian  species.  Metcalfe 
&  Chalk,  Anat.  Dicot.  2:  1002-1013.  1950,  give  an  outline  of  the 
previous  research  in  this  field:  there  are  several  types  of  anomalous 
secondary  thickening;  wedge-shaped  masses  of  phloem  in  the  xylem 
occur  (first)  and  variations  in  the  anomalous  structure  are  a  valu- 
able aid  to  the  identification  of  at  least  some  genera;  for  instance, 
in  Peru,  Amphilophium,  Anemopaegma,  Clytostoma,  Cydista,  Lundia, 
Phryganocydia,  Pyrostegia,  Tynnanthus  and  Distictella  have  similar 
structure  but  combined  successive  rings  of  growth.  As  regards  the 
few  trees,  Record  &  Hess,  "Timbers  of  the  New  World,"  is  a  use- 
ful work. 

Perhaps  the  classification  here  following  the  acceptance  of  the 
ideas  of  Miers,  Bureau  and  Schumann  has  proceeded  too  consist- 
ently or /and  expediently  on  a  basis  of  tradition  and  logic.  For  one 
over-all  picture  as  regards  generic  considerations  see  Sandwith,  Kew 
Bull.  1953:  466.  1954,  in  reference  to  Chodanthus  Miers  and  Mansoa 
P.  DC.;  these  apparently  are  not  yet  known  within  Peru  but  allied 
to  Pseudocalymma  Sampaio  &  Kuhlmann,  a  segregate  from  Adeno- 
calymma  Mart,  and  to  Onohualcoa  Lundell,  an  alliance  that  may  be 
emphasized  for  study  when  evaluating  the  presence  or  absence  of 
pubescence,  of  gland  fields  at  the  nodes  (and  elsewhere),  of  tubercles 
on  capsules,  the  number  of  rows  of  ovules  in  the  cells  or  the  charac- 
teristics of  the  pollen  grains  as  criteria  for  generic  definition.  As  to 
pollen  the  grains  may  be  furrowed  or  not  but  rarely  not  clearly;  as 
in  the  Brazilian  genus  Gardnerodoxa  Sandw.,  Kew  Bull.  1954:  611- 


FLORA  OF  PERU  5 

614.  1955,  they  may  be  a  basic  clue  in  association  with  the  more 
usual  characters  of  tendrils,  gland  fields,  number  of  ovules,  etc.  It 
must  take  a  good  deal  of  personal  spoofing  to  argue  seriously  about 
the  validity  of  many  of  the  hundred  or  so  genera  currently  keyed  out, 
not  a  few  only  negatively,  and  on  characters  developed  in  varying 
degrees  in  this  family,  all  of  them  together  with  probably  not  many 
more  species — valid  ones,  that  is.  However,  the  careful  and  sensible 
interpretations  of  the  present  specialist  as  regards  specific  variables 
suggests  that  he  is  adding  and  has  added  greatly  to  an  understand- 
ing of  the  group  relationships  so  that  one  may  infer  that  eventually 
many  names  can  be  applied  even  in  horticulture  with  confidence. 

Bignonia  L.,  Gen.  PI.  179.  1763,  commended  the  Abbe*  Jean  Paul 
Bignon,  court  librarian  to  Louis  XIV,  and  until  it  became  the  mode 
to  emphasize  dissimilarities  more  than  similarities  as  evidence  of 
natural  relationship  the  name  included  besides  B.  radicans  L.,  now 
Campsis  radicans  Seem.,  a  majority  of  the  known  species.  Ever- 
accumulating  information  and  new  methods  of  acquiring  it  have 
also  resulted  in  the  present  dissociation,  apparently  to  an  extreme 
degree  destroying  the  general  usefulness  of  the  taxonomy,  to  little 
if  any  purpose. 

Sandwith  has  observed  that  Anemopaegma  Mart.,  Distictella 
Kuntze,  and  Martinella  Baillon  have  veinlets  so  intricately  impressed 
that  under  a  lens  the  leaflets  appear  shagreened.  A  majority  of  Pe- 
ruvian species  darken,  even  blacken,  in  drying;  discoloration  unless 
merely  brownish  has  generally  not  been  indicated  in  the  descriptions. 

These  mostly  tropical  vines  and  trees  are  notably  ornamental; 
Edwin  A.  Menninger,  to  his  great  credit,  has  succeeded  in  intro- 
ducing a  number,  known  in  Peru,  at  Stuart,  Florida,  while  Catalpa 
Scop,  and  the  Trumpet  Vine  (Campsis),  sometimes  north  temperate, 
are  found  in  gardens  in  Peru;  a  useful  synopsis  of  the  former  has 
been  made  by  Paelt  (Candollea  3:  241-285.  1952). 

Dr.  Humberto  A.  Fabris,  Museo  de  La  Plata,  merits  special  ac- 
knowledgment for  his  useful  account  of  the  species  known  to  be  in 
cultivation  in  Argentina  (Inst.  Bot.  Agric.  10,  fasc.  173: 1-57. 1959); 
a  number  of  the  plants  described  and  illustrated  may  be  used  as 
ornamentals  also  in  Peru.  Dr.  Fabris'  excellent  synopsis,  with  a 
practical  generic  key,  descriptions,  illustrations  and  extensive  bibli- 
ography, is  part  of  a  series  pertaining  to  horticulture  started  in  1950 
but  which,  unfortunately,  only  recently  has  been  brought  to  my 
attention. 

A  generic  key,  after  that  of  Bureau  and  Schumann,  Pflanzenfam., 
I.e.,  and  Mart.  Fl.  Bras.,  I.e.,  and  an  artificial  one  have  been  devised, 


6      FIELD  MUSEUM  OF  NATURAL  HISTORY — BOTANY,  VOL.  XIII 

following  the  example  of  both  Seibert  and  Sandwith  for  other  areas. 
An  anatomical  key  would  be  desirable  also.  Since  most  herbarium 
material  is  only  in  flower  and  many  specimens  show  only  uppermost 
branchlets  it  has  been  necessary  to  make  secondary,  when  possible, 
the  probably  important  characters  of  mature  branches,  nodal  glands. 
The  tenuous  demarcation  of  many  generic  concepts  results  even  with 
complete  materials  in  a  correspondingly  weak  key,  often  only  sug- 
gestive, burdened  with  exceptions.  However,  Bureau  wrote  in  1864, 
in  his  monograph  of  Bignoniaceae:  "I  could  not  overemphasize  the 
importance  for  the  study  of  Bignons  of  collecting  with  care  the  fruits 
at  the  same  time  as  the  flowers;  it  is  on  the  structure  of  the  fruits  that 
one  is  forced  to  establish  the  basic  classification." 

Preparation  of  this  account  as  for  many  other  families  has  been 
tremendously  aided  by  the  cooperation  of  Ira  Wiggins  and  associates 
at  the  Natural  History  Museum,  Stanford  University,  and  by  Phillip 
Munz  and  associates  at  the  Rancho  Santa  Ana  Botanic  Garden, 
Claremont,  California;  in  both  institutions  the  special  botanical  li- 
braries are  outstanding  and  usable  because  of  ready  availability.  In 
recent  years  the  work  has  benefited  too  by  the  friendly  help  of  Mrs. 
Dorothy  M.  Halmos,  able  librarian  at  the  University  of  Southern 
California,  Hancock  Library,  where,  it  is  not  generally  known,  are 
many  rare  botanical  books  obtained  from  the  collection  of  the  Boston 
Museum  of  Natural  History.  My  indebtedness  to  my  contem- 
poraries at  the  University  of  California  and  at  our  National  Herbar- 
ium, Smithsonian,  has  been  recorded  in  other  numbers  of  this  work.

granular-puberulent  above  and  not  or  less  white  pubescent  beneath ; 
it  is  possible  that  this  taxon  is  not  more  than  a  geographic  form  or

densely  fine-tomentose  beneath,  corolla  about  2  cm.  long  (see  note 
by  I.  M.  Johnston  under  A.  tuber culata) . — Apparently  one  time  col-

In  Peru  similar  in  habit  and  vegetatively  to  Pleonotoma  but  the 
striking  ribs  (obscure  in  Peru)  only  more  or  less  quadrately  angling, 
the  branches  and  the  leaves  tri-  or  bifoliate,  the  tendrils  simple  or 
finally  bifid.  Calyx  entire.  Corolla  not  coriaceous,  glabrous,  lepi- 
dote or  pubescent.  Ovary  ellipsoid  or  ovoid-ellipsoid,  usually  much 
contracted  into  the  pulvinate  disk;  ovules  few  in  each  of  the  2-6  series. 
Capsule  shortly  ellipsoid,  stipitate,  valves  smooth,  the  midrib  scarcely 
raised  or  clearly  impressed.  Seeds  broadly  oblong  with  wide  mem- 
branous hyaline  wings  or  these  opaque,  corky,  at  least  young  seeds 
of  A.  paraense  (Sandwith). — The  variation  in  several  characters,  es- 
pecially those  of  the  ovary  and  fruit,  suggest  that  the  genus  either 
should  be  interpreted  to  include  species  now  considered  as  distinct 
groups  or  should  itself  be  divided.  Pollen  5-7-sulcate  (Gomes,  Rod-

likely  ...  to  prove  only  of  varietal  significance,  while  length  of  calyx 
teeth  is  suspect  as  a  specific  character."  This  statement  may  be

less  lenticellate-tuberculate  below,  a  few  simple  trichomes  early  pres- 
ent as  on  the  petioles,  petiolules  (1-3  cm.  long)  and  leaflets,  these 
elliptic-oblong  or  subovate,  shortly  and  obtusely  or  acutely  acumi- 
nate, or  subobtuse,  often  7-10  (15)  cm.  long,  3-5  (7)  cm.  wide, 
sparsely  lepidote,  papillose,  lustrous,  especially  above,  more  or  less 
obviously  reticulate-veined,  concolor  and  opaque  beneath  where  bar- 
bellate  in  the  axils  of  the  4-5  larger  nerves;  racemes  shorter  than 
leaves,  axillary  or  terminal,  few-flowered,  the  bracts  minute;  pedi- 
cels (with  peduncles)  10-18  mm.  long  (shorter  in  Peru);  calyx  in 
Peru  early  6-8  mm.  long,  in  type  to  1.5  cm.  (DeCandolle),  2.5-3  cm. 
long  (Schumann),  finally  to  1.5  cm.  across  above,  subevenly  bilabiate 
or  often  later  cleft,  coriaceous  and  dark  at  base,  membranous  and 
paler  above;  corolla  roseate  (Schunke),  dark  violet,  white  within  or 
deep  red-wine  (Klug),  5-  nearly  8  cm.  long  including  the  rounded 
lobes  (3  cm.  long,  DeCandolle),  puberulent  tomentulose  also  within 
near  stamen-insertion;  disk  solid,  to  17  mm.  long;  ovules  24  per  cell, 
biseriate;  capsule  prickly,  drying  dark;  seeds  pale  brown  except  the 
sordid  white  narrow  hyaline  wing  margin. — The  fruit,  rough  like  a 
wood  rasp,  and  the  seeds,  agree  exactly  with  those  of  S.  verrucosa 
(Standl.)  Seibert,  type  of  the  genus  from  Central  America  (Sand- 
with). 

The  plant  resembles  Phryganocydia  Mart,  to  which  Martius  in 
herb,  referred  it,  but  the  disk  is  well-developed.  A.  lenticettosa  Bur. 
&  Sch.  seems  to  be  material  with  closely  tuberculate  branches,  smaller 
leaflets,  subcoriaceous  calyx,  25-28  mm.  long,  orange  (?)  corolla  (type 
from  Mato  Grosso,  Brazil);  to  it  Seibert  referred  the  Schunke  collec- 
tion; the  species  is  probably  variable.  The  extra-Peruvian  synon- 
ymy, after  Seibert,  is  given  in  deference  to  the  final  decision  of 
Standley  which  seems  to  suggest  that  he  questioned  the  logical  but 
probably  unnatural  classification  in  the  family.  A  photo  of  the  Vitoc

10.    MARTINELLA  Baillon 

Trichomes  (if  present)  of  branchlets,  often  petioles,  racemes,  mi- 
nutely glandular;  immersed  nodal  glands  and  lenticels  usually  none. 
Leaves  bifoliolate,  tendril  trifid,  the  short  branches  recurved  but 
often  caducous  (or  tendril  simple),  stipules  obsolete.  Racemes  rarely 
branched  toward  base.  Flower  buds  obovoid,  apiculate.  Calyx  un- 
evenly (slightly  bilabiately)  2-3-lobed.  Corolla  more  or  less  funnel- 
form,  the  tube  glabrous  as  the  divaricate-celled  anthers.  Ovary 
sparsely  if  at  all  lepidote,  ovules  4-seriate  (biseriate,  Sampaio). 
Capsule  linear,  attenuate  both  ends,  compressed,  the  parallel  valves 
thickened  marginally,  the  middle  nerve  obscure.  Seeds  oblong, 
broadly  membranous-alate. — The  Peruvian  liana  may  be  referable 
to  the  entity  of  Sampaio,  who  distinguished  two  species  as  follows; 
but  the  characters  may  not  be  constant. 

Corolla  2.8-3  cm.  long,  lilac;  tendrils  trifid;  leaflets  herbaceous, 
9-13  cm.  long,  4-7  cm.  wide;  calyx  glabrous M.  obovata. 

Corolla  4.5-5  cm.  long,  dark  purple;  tendril  simple;  leaflets  coria- 
ceous, 14-17  cm.  long,  8-9  cm.  wide;  calyx  (lens)  densely  scaly 
and  sparsely  pilosulous M.  iquitosensis.

Branches  stout,  glabrous  but  immersed  dark  glandular  at  base  of 
nodes;  leaves  conjugate;  leaflets  yellowish-green,  concolor,  ovate- 
elliptic,  acute  or  obtusely  acuminate,  acute  at  base,  glabrous,  sparsely 
black  glandular  beneath,  the  principal  nerves  usually  5;  inflorescence 
lax,  few-flowered,  8-12  cm.  long,  dark  glandular  at  nodes,  the  ped- 
icels strongly  pilosulous;  calyx  drying  black,  in  bud  obconic-elliptic, 
becoming  3-lobulate,  glabrous  within,  lepidote  and  sparsely  pilose 
without,  16-18  mm.  long;  corolla  arcuate,  glabrous  about  two-thirds 
below,  the  lobes  puberulous,  4-8  mm.  long,  the  tube  1.5  cm.  long;  sta- 
mens subequal,  pollen  trisulcate,  exine  reticulate;  disk  1  mm.  high; 
ovary  narrowed  at  both  ends,  glabrous;  ovules  biseriate,  about  36. 
— If  this  is  distinct  from  M.  obovata,  as  seems  probable  on  the  basis 
of  the  biseriate  ovules  (accurately  observed?),  probably  all  the  Peru- 
vian specimens,  at  least  those  from  the  region  of  Iquitos,  belong  to  it.

Scandent  by  trifid  tendrils  replacing  the  terminal  leaflet  of  some 
of  the  trifoliate  leaves,  the  foliose  branchlets  strongly  fibrous,  the 
prominent  fibrous  ribs  effaceable.  Nodal  gland  areas  obsolete;  pseu-

contracted  above  the  conspicuous  pulvinate  disk,  ellipsoid,  softly 
appressed  spinulose;  ovules  pluriseriate.  Capsule  ligneous,  flattened- 
ellipsoid,  densely  echinate  with  a  subquadrangular  apical  appendage, 
the  prickles  more  or  less  persisting;  seeds  oblong,  the  body  thin,  the 
hyaline  wings  very  broad. — Sandwith  well  describes  the  pod;  sterile 
part  of  septum  thin,  flattened  and  with  broad  margins  flattened  at 
right  angles;  these  are  formed  by  the  seminiferous  borders  bent  at 
right  angles  to  the  septum  proper,  thus  coming  to  be  in  the  same 
plane  so  that  the  entire  structure  resembles  two  shallow  trays  back 
to  back.  Pollen  not  sulcate  (Gomes,  Rodrigue"sia  20:  130,  fig.

Branchlets  finely  striate,  early  densely  pulverulent  or  pubescent, 
usually  glabrate  and  lenticellate  in  age;  leaflets  ovate-  or  elliptic- 
oblong,  obtuse  or  rounded  at  base,  shortly  acuminate,  a  dm.  or  two 
long,  about  half  as  wide,  finally  coriaceous,  glabrous  but  punctate-

the  4-5  lateral  nerves  typically  arcuate-ascending,  the  veinlet-reticu- 
lation  impressed  on  both  surfaces;  thyrses  or  racemes  narrow,  1-2  dm. 
long,  branches  1-  or  3-flowered;  calyx  subcampanulate,  9-14  mm. 
long,  minutely  tomentulose,  often  purplish  (dried)  and  with  large 
gland  areas  above;  corolla  white,  campanulate-funnelform,  5-6  cm. 
long,  limb  about  5  cm.  across;  style  pubescent;  capsule  tomentulose 
and  with  many  impressed  platiform  glands,  12-14.5  cm.  long,  4-5  cm. 
broad. — After  Sandwith  (as  most  descriptions),  who  notes  (as  Brit- 
ton)  Spruce  1721  as  conspecific  but  leaves  more  oblong,  broadly 
rounded  at  base,  the  nerves  more  spreading.  Collected  in  Bolivia 
on  the  Rio  Madre  de  Dios  it  is  to  be  expected  within  Peru  on  the 
same  river.  Similar,  but  less  likely  to  be  encountered  is  D.  magno- 
liifolia  (HBK.)  Sandw.  Lilloa  3: 460. 1938,  the  veinlets  elevated  both

obsolete.  Stipules  subulate,  lanceolate,  usually  striate  in  age.  Thyrse 
terminal,  many-flowered.  Calyx  campanulate,  subtruncate  or  lobed 
unevenly.  Corolla  funnelform,  in  bud  velvety,  in  anthesis  more  or 
less  scurfy  tomentose.  Anthers  glabrous,  cells  divaricate,  connective

Scandent,  the  tendrils  simple  and  the  acutely  quadrate  branchlets

form  as  those  of  Tynnanthus  but  the  exine  is  uniformly  reticulate 
(Pichon,  Bull.  Soc.  Bot.  France  92:  229.  1945)  instead  of  smooth 
(Urban)  as  in  the  other  genus,  and  the  grains  are  trisulcate,  which 
character  together  with  distinctly  bilabiate  corolla,  short  disk,  curved 
anther  cells  favors  alliance  with  Tynnanthus  to  which  Schumann, 
Standley  and  Sprague  at  different  times  referred  specimens,  but 
branchlets,  pseudostipules,  lack  of  indument  within,  peculiarly  col- 
ored lepidote  corolla  (except  on  limb),  and  shorter  calyx  make  actual 
identification  with  Miers'  group  inadvisable  (Sandwith).  In  many 
families,  may  I  venture  to  remark,  the  four  characters  mentioned 
first  would  be  considered  as  more  indicative  of  natural  generic  char- 
acterization than  the  latter.

lobulate,  glandular-lepidote  to  sparsely  pubescent,  1.5-2.2  mm.  long; 
corolla  1.5-2  cm.  long,  stipitately  glandular-lepidote,  the  tube  ab- 
ruptly expanded  at  base;  capsule  (immature?)  17.5  cm.  long,  5.5  cm. 
broad,  broadly  attenuate-acuminate,  thin  valves  lustrous,  smooth 
but  obviously  undulate-rugulose  (Sandwith  from  Philipson  21  -40, 
probably  this  species). — Well-developed  corollas  scarcely  to  2  cm. 
long,  often  much  shorter,  longer  stamens  less  than  1.5  cm.  long, 
anther  cells  hardly  1.5  mm.  long;  the  Peruvian  record  is  by  Pav6n 
without  data  in  Herb.  Dunant,  Paris,  according  to  Sandwith,  who,

variant  of  M .  Prieurei  (DC.)  Bur.  of  Suriname  and  British  Guiana, 
corollas  3.5-5  cm.  long,  but  leaflets  tend  to  be  more  ovate,  thyrse 
laxer.  However,  there  may  be  a  difference  in  capsules  at  least 
as  to  size  (see  Sandwith,  I.e.),  that  of  the  eastern  ranging  plant 
apparently  being  much  larger,  roughly  and  conspicuously  rugose-

In  part  scandent  with  terete  finely  costulate  branchlets  (no  gland- 
areas)  that  early  are  densely  tomentulose  as  the  petioles  and  petio- 
lules.  Stipules  if  apparent  not  large.  Leaflets  3  or  2  (tendril  simple 
or  none),  sometimes  dentate,  always  conspicuously  lepidote-punctate 
beneath.  Inflorescence  a  short  raceme,  axillary  or  terminal.  Calyx 
campanulate,  membranous,  more  or  less  pubescent  and  inflated,  cos- 
tate,  unevenly  lobate.  Corolla  bright  to  pale  yellow  (Peru),  purple 
or  white,  campanulate-funnelform,  pubescent  and  lepidote  without. 
Anthers  glabrous,  connective  extended  above  the  spreading  cells. 
Disk  shallowly  cupulate-pulvinate.  Ovary  oblong,  lepidote,  ovules 
2-4-seriate.  Capsule  very  narrowly  elongate-linear,  valves  parallel, 
smooth,  long-attenuate,  faintly  ribbed.  Seeds  narrowly  oblong, 
broadly  membranous-alate. — Adenocalymma  Mart.,  which  is  simi-

corolla;  quite  possible  that  it  is  not  more  than  an  indumentum  vari- 
ety of  a  very  variable  collective  species  (S.  riparia),  including  S.  per- 
foratum  (Sandwith,  Kew  Bull.  1954:  607.  1955);  most  of  the  Peru

Slender  younger  branchlets  more  or  less  glandular  at  nodes  and, 
as  the  inflorescence,  leaves  puberulent  especially  beneath;  leaflets 
ovate  or  ovate-oblong,  cordate  at  base,  obtusely  acuminate,  about 
1  dm.  long,  half  as  wide  or  smaller,  rarely  twice  as  large,  usually

neath; calyx  cupulate-campanulate,  yellow,  6-10  mm.  long,  subcori- 
aceous  and  puberulent  below  the  unevenly  splitting  margin,  this  early 
minutely  denticulate;  corolla  elongate-funnelform,  crimson-red,  sub- 
tomentose,  5.5-6  cm.  long,  longer  stamens  unequal,  3  cm.  long, 
affixed  23-27  mm.  above  the  base;  filaments  glabrous,  anthers  bar- 
bate; ovules  4-seriate. — An  aberrant  species  in  the  presence  of  nodal 
glands,  exserted  stamens  and  extraordinarily  reticulate  pollen,  the 
segregation  of  M.  Pichon  perhaps  justifiable,  at  least  logically.  How- 
ever, as  to  glands,  areas  of  these  are  usually  developed  near  nodes  of 
specimens  referred  to  L.  Spruceana  Bur.  Capsule,  according  to  Pichon, 
11.5-42  cm.  long,  9-25  mm.  wide,  valves  acute,  plane,  coriaceous, 
smooth  except  the  prominent  midnerve;  seeds  large,  broadly  hyaline 
alate.  Apparently  unknown  from  Amazonian  Brazil,  the  identifica- 
tion therefore  rather  questionable  or  the  specimen  incorrectly  labeled.

Like  Cydista  Miers  but  tendrils  shortly  trifid,  veinlets  (ultimate) 
impressed,  seed  wings  membranous  or  papery,  pollen  grains  pluri- 
sulcate,  reticulate. — In  several  families  (as  Gentianaceae)  the  char- 
acter of  the  pollen  grains  alone  as  a  significant  generic  indicator  has 
been  disputed;  it  may  be  noted  that  the  few  other  differences  are 
relative  or  inconstant  elsewhere  in  this  family;  this  genus  agrees  with 
Cydista  in  the  lepidote  corolla  and  ovary  and  in  the  absence  of  disk, 
as  noted  by  Sandwith;  Urban  based  it  chiefly  on  the  trifid  tendrils, 
many  sulcate  pollen  grains,  following  a  suggestion  of  Sprague. 

Wilhelm  Konrad  Roentgen  was  a  Nobel  Prize  winner,  1901 
(Roentgen  rays),  also  a  humanitarian  (Urban).

Scandent,  branches  subterete,  leaves  mostly  trifoliate.  Panicles 
typically  on  older  leafless  branchlets.  Calyx  tubular,  truncate,  more 
or  less  unevenly  lobed  or  cleft  in  age.  Corolla  funnelform,  puberu- 
lent within  at  stamen  insertion.  Anther  cells  nearly  horizontally 
divaricate.  Style  quadrate.  Disk  cupulate.  Ovules  6-8-seriate. 
Fruit  valves  ligneous,  thick,  broad,  finally  longitudinally  parting. — 
The  fruit  is  thus  quite  different  from  that  of  Saldanhaea;  besides, 
the  anther  cells  are  straight,  young  style  quadrate,  ovules  many. 

As  in  Stizophyllum  the  flowers  may  be  yellow.  Pollen  grains 
monads  with  three  colpae  distinguishing  this  genus  sharply  from 
Saldanhaea,  whose  pollen  grains  are  united  into  tetrads  (author). 
This,  as  many  genera,  rests  on  the  interpretation  of  the  salient  char- 
acters whether  of  generic  or  sectional  import.  Similar  pollen  charac- 
ters are  present  in  other  families,  as  in  Gentianaceae. 

Indument,  especially  younger  parts,  yellow,  as  corolla.

Branchlets  terete,  without  nodal  glands  or  impermanent  ribs. 
Petioles  and  petiolules  tumid  at  both  ends.  Leaves  (unless  upper- 
most) pinnate  to  tripinnate  or  biternate,  the  simple  or  trifid  tendril 
often  developed  instead  of  the  third  basal  or  terminal  pinnae;  upper- 
most leaves  sometimes  bi-trifoliolate  (former  with  tendril) ;  compare

split  and  lobed.  Corolla  yellow,  funnelform  or  rather  campanulate 
and  long-cylindric  below,  glabrous  as  the  divaricate  celled  anthers. 
Disk  thick,  annular-pulvinate.  Ovary  glabrous  or  lepidote,  ovules 
biseriate.  Capsule  elongate-linear,  compressed,  the  parallel  valves

almost  entirely  corky  (Miers) .  At  present  the  only  satisfactory  char- 
acters by  which  Memora  can  be  separated  from  Adenocalymma  are 
the  pinnate  or  bipinnate  leaves  (except  the  uppermost!)  and  the 
glabrous  (without)  corolla,  and  the  latter  character  breaks  down  in 
the  instance  of  A.  impressum  (Sandwith,  I.e.  212,  cf.  note  under 
Pseudocalymma)  who  also  observes  (and  renames  to  Adenocalymma)

medially,  or  more  or  less  bilabiate,  the  midrib  of  the  posterior  sepal 
shortly  produced.  Corolla  funnelform,  glabrous  (also  within)  as  an- 
thers, these  with  connective  extended.  Disk  variously  low-pulvinate. 
Ovary  oblong-linear,  ovules  2-4-seriate.  Capsule  compressed,  smooth

The  plant  described  by  Kranzlin  as  M .  auristellae  from  a  vegeta- 
tive scrap  is  obviously  a  juvenile  state,  possibly  in  this  family  and

in  Bauhinia.  Since  simple,  serrate,  lobate-serrate  and  bifoliate  leaves

variability  within  the  species  is  proven  by  ample  material,  all  six 
species  will  probably  be  united.  However,  Cuatrecasas,  as  Dugand, 
referred  Colombian  specimens  to  J.  rachidoptera.  Huber  indicated 
that  J.  cauliflora  might  include  the  Peruvian  trees;  indument, 
winged  to  wingless  rachis,  flower  color  and  constancy  of  inflores-

leaflets;  the  var.  rhombifolia  (G.  F.  W.  Meyer)  Sandwith,  I.e.,  has

Like  Tabebuia  but  in  Peru  shrubs  or  trees  expediently  separable 
by  imparipinnate  leaves,  rarely  on  young  shoots,  in  part  or  all  simple, 
if  with  3  leaflets  the  lateral  smaller.  Racemes  or  panicles  terminal 
or  upper-axillary.  Corolla  pubescent  or  papillate  within. — As  sug- 
gested by  DeCandolle,  Prodr.  9:  212.  1845,  seems  quite  arbitrarily 
restricted  and  the  earlier  name,  this  abbreviated  from  the  usual 
native  one  of  Mexico.  Unlike  Jacaranda  in  the  short  inconspicuous 
staminode,  the  much  longer  stamens  (both  anther  cells  fertile)  gla- 
brous or  pilose,  included  or  exserted. 

The  more  common  Andean  species  are  medium-sized  trees  char- 
acteristic, with  Schinus  molle  and  Caesalpinia  tinctoria,  of  the  dryer 
coastal  and  inter-Andean  regions  and  with  the  same  range  (Weber- 
bauer).  Spruce  noted  native  names  "Tauari"  and  "Carajuru"  and 
"Carajuru  piranga,"  while  Poeppig  in  his  famous  Reise  mentioned 
probable  species  as  "Ambira;"  Williams  interpreted  the  first  name 
as  "Ta  huari"  (amarillo  y  negro).

Glabrous  shrub,  branches  purpurescent,  petioles  alate;  leaves  5 
pairs  of  oblong  dentate  leaflets  nearly  2.5  cm.  long,  10-16  mm.  wide,

cles axillary  in  a  lax  terminal  many-flowered  panicle;  calyx  glabrous, 
acutely  5-lobed. — In  open  inflorescence  and  alate  leaf  rachis,  this

than  the  Herb.  Prodromus  specimen  (Negative  7675)  by  Dombey,

late.  Really,  unless  the  calyx  shape  is  significant,  the  recorded  dif-

More  or  less  pubescent  to  nearly  glabrous  shrub,  the  brown  bark 
fragile;  leaflets  2-4  pairs,  oblong,  obtuse  or  acute,  serrate,  partly 
pilose  beneath  only,  lateral  to  3  cm.  long,  half  as  wide,  terminal  to 
1  dm.  long;  rachis  sometimes  compressed,  glabrous  or  as  petioles, 
puberulent;  calyx  nearly  minute,  3X3  mm.  (type),  usually  some- 
what longer  but  campanulate,  denticulate;  corolla  outside  red,  nar- 
rowly short-tubular  at  base  (where  villous  within),  funnelform,  bilab- 
iate, 5.5  cm.  long,  1  cm.  across  at  top;  stamens  to  6  cm.  long;  disk 
fleshy,  crenate;  capsule  1-1.5  dm.  long,  4-6  mm.  broad. — Type  from 
Ecuador,  the  flowers  2.5  cm.  long,  those  of  T.  azaleiflora  3.5  cm.  long, 
filaments  glabrous  in  both  these  types.  Sandwith,  Kew  Bull.  432.

this  is  a  very  variable  species,  especially  in  the  indumentum;  he  indi- 
cates he  is  inclined  to  believe  the  synonymy  of  Seemann  and  to  add 
the  plants  of  Kuntze  and  Kranzlin  (this  ex  char.),  and  perhaps  others

Glabrous  tree,  the  branches  compressed;  leaves  imparipinnate, 
terminal,  simple,  intermixed,  the  leaflets  (2)  3-5  pairs,  oblong  (acute 
or  obtuse),  acuminate,  serrate,  reticulation  venose,  nerves  prominent 
beneath,  lustrous  above,  lateral  leaflets  3.5  cm.  long,  1.5  cm.  wide;

ulate,  acutely  dentate;  corolla  funnelform,  2.5-3.5  cm.  long;  anthers 
puberulent  (Melchior);  ovary  glabrous;  capsule  1  dm.  long,  com- 
pressed, verruculose,  glabrous;  seeds  flat,  membranous-margined.— 
Rather  distinct  from  T.  stans  in  the  form  of  the  leaves  (HBK.),  a 
questionable  distinction;  no  specimens  seen  by  me  at  this  time  (1960). 
The  acuminate  leaflets  contrast  with  T.  rosaefolia  HBK.  (Sandwith). 
Killip  &  Smith  21780  shows  rounded  or  obtuse  leaflets  and  acutely 
acuminate  ones.  New  shoots  may  have  simple  leaves  (Melchior). 
There  is  a  var.  multijugum  R.  E.  Fries,  type  from  Argentina;  this 
plant  is  certainly  a  part  of  T.  stans  (Herzog),  an  opinion  shared  by 
me.  Type  from  Montan,  Peru  (Bonpland).  Flowers  yellow  with

Flowers  without,  except  branchlets,  petioles  and  subterete  leaf 
rachis  glabrous  (except  variety),  unevenly,  remotely  and  minutely 
lepidote;  leaves  punctate  beneath,  the  midrib  pilose;  leaflets  1-3

inflorescence  of  T.  stans  (simple  or  nearly),  tomentose  ones  that  of 
T.  castanifolia  (as  T.  sorbifolia  HBK.)  and  so  are  probably  distinct. 
Originally  from  Mexico,  may  be  not  native  in  Peru  or  should  include 
several  variants  described  as  distinct  species.  A  shrub  or  small  tree

of  its  bright  yellow  flowers  over  long  periods,  the  flexible  branches 
used  in  basketry.  Jussieu  did  not  give  the  source  of  the  name  (not 
required  in  his  day),  so  I  consider  the  transfer  as  by  him  (as  did  Schu-

7  cm.  long,  attenuate  into  disk  1  cm.  long. — Stafford  collections  agree 
with  original  description;  pinnate  and  simple  leaves  on  the  same 
branchlets.  Weberbauer  noted  a  form  with  pinnate  leaves;  these 
have  3-7  leaflets.  Some  simple  leaves  are  7  cm.  long,  3  cm.  wide. 
It  is  clear  that  the  taxonomy  of  the  Peruvian  and  Bolivian  species 
of  Tecoma  can  be  understood  only  from  field  studies  (Sandwith).

fide  author,  very  much  like  T.  stans  but  differs  in  the  leaves  and 
smaller  flowers;  all  of  the  former  seen  by  him  were  trifoliolate,  not

fimbriolate;  anther  cells  strongly  divergent,  the  larger  2  cm.  long; 
style  2  cm.  long;  disk  minute. — There  are  also  simple  leaves.  If  dis- 
tinct from  T.  castanifolia  (D.  Don)  Melchior  it  must  be  on  the  basis 
of  much  narrower  flowers,  much  less  inflated,  and  rarely  more  than 
3  cm.  long;  it  is  probably  a  pubescent  state  of  T.  Gaudichaudii  and

foliolate  leaves  (no  pseudostipules)  and  short  terminal  or  axillary 
dichasia  or  racemes.  Calyx  campanulate  to  elongate-tubular,  clearly 
lobed,  often  bilabiately,  lepidote,  stellate  pubescent  or  tomentulose. 
Corolla  about  funnelform,  rarely  subhypocrateriform,  the  lobes  usu- 
ally ciliate,  frequently  pubescent  within.  Anthers  glabrous,  cells 
divaricate,  the  sterile  one  much  shorter.  Disk  patelliform  or  cupu-

several  species  are  cultivated  in  Argentina.  Unless  for  convenience,

To  this  genus  Williams,  Field  Mus.  Bot.  15:  447.  1936,  referred,

(Tecoma  rosea  Bertol.  Fl.  Guatimal.  25.  1840),  famous  for  its  wood 
known  as  "Roble  morado;"  the  5-digitate  leaves  and  calyx  are  densely 
lepidote.  It  is  in  Ecuador!  (Sandwith,  Kew  Bull.  1953:  454.  1954).

calyx  tomentose  or  glabrate,  slightly  lepidote,  teeth  puberulous  or 
villous;  corolla  tube  glabrous,  the  limb  puberulent  apically  and  with- 
in ventrally  sparsely  short-  or  long-pilosulous;  ovary  lepidote. — 
Kranzlin's  type  was  from  a  leafless  tree,  branches  torulose-cicatrose, 
glabrous,  corolla  sparsely  paleaceous-pilose  within,  to  8  cm.  long, 
6-7  cm.  across  apically;  ovary  sulcate,  glabrous.  The  inflorescence 
is  separate  on  Pavon's  type,  also  on  duplicate  sheet  at  Geneva;  the 
calyx  is  lepidote,  and  Sandwith  wondered  if  the  material  belongs  to 
one  species,  the  branches  and  leaflets  densely  pubescent  with  branched 
trichomes;  perhaps  type  in  fact  is  T.  capitata,  but  the  flowers,  often 
precocious,  are  then  on  separate  twigs.  T.  Hassleri  Sprague,  Bull.

without,  ventrally  puberulous  within,  lobes  rounded,  14  mm.  long; 
disk  low;  ovary  glabrous. — Inflorescence  accompanied  by  leaves 
(Schumann),  perhaps  not  constantly;  also  said  to  be  distinguished 
from  T.  capitata  (Bur.  &  Sch.)  Sandw.  I.e.  (to  be  expected  in  south- 
eastern Peru)  by  the  clearly  stellate  pubescent  younger  leaflets  (both 
sides),  very  rusty  calyx,  and,  especially,  shorter  almost  scurfy  rigid 
trichomes  on  anterior  inner  side  of  corolla  tube;  the  also  similar 
T.  serratifolia  (Vahl)  Nicholson  has  corollas  less  densely  and  weakly 
long-pilose  within;  the  ovary  of  T.  capitata  (perhaps  T.  obscura)  may 
lack  the  flat  glands  very  obvious  on  that  of  Vahl's  plant  (Sandwith) . 
All  these  characters,  from  the  few  specimens  seen,  may,  it  seems  to 
me,  prove  variable.

Branchlets  and  foliage  glabrous  or  nearly,  somewhat  puberulous 
when  young  and  the  leaflets  pilose  in  the  nerve  axils  beneath,  mi- 
nutely lepidote  but  with  no  scaly  coat;  leaflets  3  (always?),  rather 
ovate,  mostly  cuneate  at  base,  acuminate,  highly  variable  in  size, 
the  larger  terminal  one  often  a  dm.  long  or  longer,  usually  somewhat 
less  than  half  as  wide,  sometimes  crenate,  papery  to  coriaceous,  ulti- 
mate veinlets  scarcely  raised  above,  not  at  all  beneath,  extremely 
intricately  reticulate;  inflorescences  ordinarily  on  leafless  branchlets, 
the  cymes  or  1-flowered  pedicels  in  umbelliform  fascicles;  calyx  finely 
stellate  pubescent;  corolla  6-8  cm.  long,  yellow,  glabrous,  but  some- 
what and  weakly  long-pilose  within;  ovary  grooved,  sparsely  lepidote, 
more  or  less  tubercled  with  patelliform  glands,  ovules  pluriseriate; 
capsule  linear,  attenuate  to  apex,  attains  at  least  4.5  dm.  in  length, 

2  cm.  in  width. — Earliest  name  for  several  similar  trees,  perhaps  dis-

the  corolla  is  apparently  not  papillose,  is  tomentulose  within,  the 
stamens  only  half  as  long  as  corolla,  the  capsule  12-angled,  12-sul- 
cate, but,  even  so,  perhaps  the  species  is  variable  in  these  characters 
as  in  pubescence,  this  a  puberulence  more  or  less  developed,  some- 
times lacking.  It  may  also  be  significant  that  no  examples  outside 
of  the  influence  of  some  cultivation  have  been  recorded.

Tree  resembling  Tabebuia  and  Cybistax  but  the  small  flowers  with 
pilose  stamens,  and  the  fruit  costate  as  in  the  latter.  Leaves  mostly 
7-foliolate.  Fl owers  many,  corymbosely  crowded.  Kranzlin  remarked 
the  apparent  weakness  of  this  segregate.  This  is,  obviously,  as  so 
often  in  this  family,  an  arbitrary  genus,  proposed  by  the  author, 
surely,  as  a  courtesy;  F.  Ducane  Godman  (with  Osbert  Sabin)  edited

long  (or  longer);  filaments  finally  about  2  mm.  long,  villous  as 
staminodes  toward  base  (Monachino)  or  papillose  (Sandwith,  var.)  ; 
fruit  to  12  mm.  in  diameter  (Sandwith).  —  Mostly  after  Ducke's 
description,  I.e.,  where  he  gave  a  key  to  the  Amazonian  and  Guiana 
species.  Liana  or  6-meter  tree,  the  flowers  white  (Klug);  this  was 
given  an  herbarium  name  after  Peru  by  Standley  and  is  var.  ma- 
crandra  Sandw.  I.e.  303,  glabrescent,  corolla  lobes  to  7.5  mm.  long,

Leaves  elliptic  or  suboblong,  rounded  at  base,  obtuse,  shortly 
petioled,  glabrous,  coriaceous,  lustrous  above,  1-1.5  dm.  long,  mar- 
ginally recurved;  racemes  to  9  cm.  long;  pedicels  1-3  mm.  long; 
calyx  5  mm.  long,  later  3^4  mm.  high,  to  8  mm.  across,  entire  or 
suberose;  corolla  cylindric,  to  1  cm.  long,  obliquely  lobed,  lobes 
2  mm.  long;  stamens  inserted  lower  third  of  tube,  smooth  as  shortly 
bilobed  style;  drupe  fleshy,  10-13  mm.  in  diameter.  —  After  Briquet; 
Kuhlmann  noted  6-9  nerves,  fleshy  glands  at  leaf  -base,  black  gland- 
ular pores,  inflorescence  racemose-paniculate,  corolla  tube  pilose 
within  as  segments  and  subacute  anther  cells;  Grisebach  described  a 
short  terminal  corymb,  younger  leaves  powdered  with  white  points, 
calyx  cylindric,  2-lipped;  anther  cells  blunt.  —  Probably,  as  Sandwith 
suggested,  these  apparent  differences  are  within  the  variation  range 
of  a  single  species.  Branches  may  root  at  nodes;  large  plate-shaped 
glands  are  at  base  of  leaves  beneath;  Kuhlmann's  plant  I  regard 
as  simply  a  white-flowered  form,  and  S.  scandens  should  probably 
be  reduced  to  S.  violacea  (Aublet)  Griseb.  Fl.  Brit.  West  Indies  445.

42.    CRESCENTIA  L. 

Small  pale-barked  trees  with  gourd-like  indehiscent  fruits,  simple 
(Peru)  or  trifoliolate  leaves  disposed  spirally  in  alternate  fascicles

(2  or  3  leaves)  and  openly  campanulate  flowers,  1-3-pedunculate 
on  the  old  wood,  the  very  broad  tube  dilated  and  transversely 
plicate  below  the  middle. 

A  curious  unmistakable  ornamental  plant,  the  thin  hard  shell 
of  the  fruit  sometimes  used  as  a  container,  often  carved  or  decorated 
as  is  the  squash;  the  thick  wingless  seeds,  after  removal  of  the 
pulp,  are  edible  when  cooked. 

The  African  Kegelia  pinnata  (Jacq.)  DC.  with  pinnate  leaves, 
racemose  broadly  campanulate  orange  or  wine-red  flowers,  5-lobed 
calyx,  and  elongate-ellipsoid  fruits  (similar  to  Crescentia)  was  col- 
lected by  Soukup  without  data. 

Otto  Porsch,  Oesterr.  Bot.  Zeitschr.  80:  31-44.  1931,  gave  an 
interesting  account  (with  bibliography  and  illustrations)  of  Crescentia 
as  a  "Fledermausblume"  (visited  by  bats). 

Crescentia  cujete  L.  Sp.  PI.  1:  626.  1753;  83. 

Leaves  more  or  less  oblanceolate,  long-attenuate  to  base,  rounded 
to  shortly  cuspidate,  chartaceous,  lustrous,  glabrous,  or  pilosulous 
beneath  on  the  nerves;  calyx  deeply  split;  corolla  usually  yellowish- 
or  greenish-white  with  red -purple  veins,  4-7  cm.  long;  disk  thick, 
yellowish;  fruit  variable  in  shape  and  size,  sometimes  3  dm.  long.— 
Widely  cultivated  and  apparently  naturalized,  as  in  Loreto  where 
often  in  water  (Tessmann);  sometimes  20  meters  tall;  Williams, 
Field  Mus.  Bot.  15:  445.  1936,  found  it  as  an  escape  and  gave  a 
description  of  the  hard  wood,  useful  for  handles,  etc.

Half-shrubs  or  scandent,  the  stems  sulcate-angulate,  the  opposite 
leaves  finely  bi-  or  tripinnate,  the  petioles  produced  into  a  branched 
tendril;  peduncles  opposite  the  leaves  terminating  in  a  lax  few- 
flowered  pendulous  raceme  of  bicolored  flowers.  Calyx  amply  tubu-

Eccremocarpus  huainaccapac  Vargas,  Bol.  Soc.  Peru.  Bot.  1: 
15.  1948. 

Pilose  slender  shrub-liana,  the  leaves  with  2-3  pairs  of  oval 
leaflets;  flowers  in  axillary  racemes,  the  peduncles  2-2.5  cm.  long, 
often  10  or  12;  bracts  oval-lanceolate,  2-2.5  cm.  long,  4-5  mm.  wide; 
calyx  fulvous,  4.5  cm.  long,  pilose,  the  segments  acute;  corolla  yellow, 
to  6  cm.  long,  the  small  glaucous  pilose  lobes  lightly  curved;  capsules 
3  cm.  long,  the  membranous  alate  seeds  4  mm.  long. — Apparently 
nearest  E.  longiflorus  as  suggested  by  the  author,  and  probably  the 
Cuzco  specimens  so  determined  actually  are  referable  to  this  southern 
representative  of  the  genus.  Also,  Vargas  5956  from  near  Penas, 
Province  of  Urubamba,  determined  by  Vargas  as  E.  viridis  R.  &  P., 
is  either  a  rather  notable  range  extension  or  points  up  the  apparently 
tenuous  characters  between  these  similar  plants.  The  author's  happy 
choice  of  name  gives  botanical  recognition  to  the  last  Inca  king, 
Huainaccapac.

subfiliform,  5-7  cm.  long;  calyx  (in  flower)  5  cm.  long,  about  3  cm.

Similar  to  Eccremocarpus  R.  &  P.  but  pedicels  short,  calyx  small, 
not  inflated,  corolla  ventricose,  anther  cells  distinct  above,  divaricate, 
capsules  stiped,  long-ovoid. — Flowers  orange-red,  several  to  many, 
about  equaled  by  the  ascending  pedicels.  Ruiz  and  Pav6n  included 
this  in  their  genus  but  their  description  of  calyx,  corollas  and  anthers 
applies  to  Eccremocarpus  viridis  R.  &  P.  The  genus  perhaps  merits 
recognition  as  a  logical  segregate  in  a  family  containing  many  similar 
traditionally  maintained  groups;  however,  Karl  Schumann,  Pflanzen- 
fam.  4,  Abt.  3b:  244,  fig.  98.  1894,  and  apparently  all  later  students 
followed  DeCandolle  in  regarding  it  as  representing  a  section.  Dar- 
win, in  his  On  the  Movements  and  Habits  of  Climbing  Plants,  used  this 
plant  as  one  example  (Hooker,  Bot.  Mag.  3:  35,  pi.  6408.  1879).

Dombeya  L'He>.  Stirp.  Nov.  1:  33.  1784. 

A  glabrous  herb  forming  tangled  masses  or  scandent,  dichoto- 
mous  as  to  branches.  Leaves  opposite,  ternately  pinnate,  one  of 
the  two  lower  pinnae  produced  into  a  finely  branched  tendril;  spike 
bracteate  and  largely  sterile  toward  apex,  the  sterile  calyces  colored. 
Calyx  biparted,  the  narrow  acuminate  upper  lobe  entire,  sometimes 
corniculate  posteriorly,  the  lower  4-crenulate.  Corolla  purple-violet, 
tubular,  the  upper  lip  cupulately  produced,  enveloping  the  4  sta- 
mens. Ovary  reflexed,  asperous,  early  4-celled,  ovules  many,  uni- 
seriate.  Capsule  ovoid,  coriaceous,  echinate,  2-celled,  the  2  valves 
apically  dehiscent,  alately  extended  each  side,  thus  nearly  4-celled. 
Seeds  few,  compressed,  alate  all  around. — Named  for  La  Tourette,

COLUMELLIACEAE  Lindl. 

Closely  branched  shrubs  or  small  trees,  the  younger  parts  seri- 
ceous-canescent  with  minute  trichomes.  Leaves  apparently  entire 
or  with  a  few  serrations,  petioles  somewhat  connate  at  base,  stipules 
none.  Flowers  hermaphrodite,  slightly  irregular,  in  terminal,  often 
furcate  cymes.  Calyx  tube  adnate  to  the  nearly  completely  inferior 
ovary,  the  5  lobes  scarcely  imbricate.  Stamens  2,  affixed  near  base, 
the  anther  cells  usually  strikingly  2-3-coiled  on  an  irregular  dilated 
connective.  Style  short,  thick,  stigma  shortly  2-4-1  obed.  Ovary 
hemispheric,  ovules  many  on  2  parietal  bifid  placentae  that  project 
into  the  axis  of  the  cell,  then  coalesce  to  form  a  partly  2-celled  ovary. 
Capsule  septicidally  2-valved,  the  valves  bifid  in  the  persisting  calyx. 
Seeds  many. — Similar  to  Gesneriaceae.

Since  the  above  data  were  assembled  a  taxonomic  introduction 
to  "a  comparative  anatomical  and  taxonomic  study"  now  in  progress 
by  W.  L.  Stern  and  G.  K.  Brizicky  has  appeared,  written  by  the 
latter,  Journ.  Am.  Arb.  42: 363-372. 1961.  According  to  Dr.  Brizicky 
the  usually  5  calyx  lobes  may  be  4,  6,  possibly  8;  stamens,  rarely  3, 
and  he  cites  Erdtman,  Pollen  Morphology  and  Plant  Taxonomy,  who 


FLORA  OF  PERU  103 

recorded  pollen  grains  as  somewhat  different  in  size  for  C.  oblonga, 
C.  obovata,  C.  sericea.  Finally,  as  to  Peru,  Brizicky  distinguishes 
C.  oblonga  particularly  by  the  leaves,  these  obviously  inequilateral, 
pergamentaceous  to  subcoriaceous,  the  lateral  nerves  distinct,  and 
recognizes  C.  sericea  (including  C.  Mathewsii)  as  a  subspecies,  in 
more  or  less  degree  with  entire  leaves,  subcampanulate  corolla,  well- 
adnate  filaments;  he,  no  doubt  correctly,  reduces  my  C.  Andrei  to

1922,  but  remarks  that  C.  lucida  may  eventually  prove  to  be  treated 
best  as  a  variety  of  C.  oblonga  R.  &  P.,  subsp.  sericea  (HBK.)  Bri- 
zicky; his  morphological  synopsis  is  commendable  for  the  careful 
observations. 

OROBANGHACEAE

1930. 

Yellowish-brown,  leafless  (leaves  reduced  to  scales),  stout,  bracte- 
ate,  glandular-pubescent  plants  with  funnelform  bilabiate  4-merous 
corollas,  deeply  5-dentate  calyces,  the  latter,  as  the  former,  more  or 
less  persisting  in  fruit.  Stamens  affixed  below  middle  of  corolla  tube. 
Ovary  1-celled  with  2-4  parietal  placentae;  style  elongate,  stigma 
conspicuous.  Capsule  2-valved,  seeds  many. — Family  has  been  re- 
garded as  a  parasitic  development  of  the  Gesneriaceae  or  the  Scroph- 
ulariaceae,  the  ovary  of  the  latter  rarely  2-celled.

Glandular  pubescent  unless  in  age,  even  the  flowers,  except  the 
corolla,  glabrous  below,  glandular-pilose  above;  stem  sometimes 
branched  at  strongly  clavate  base,  more  or  less  squamate,  to  2.5  dm. 
tall;  scales  ovate-lanceolate,  to  2  cm.  long;  spikes  elongate-cylindric, 
obtuse,  laxly  flowered  only  toward  base;  bracts  lanceolate-elliptic, 
acute,  to  1.7  cm.  long,  5  mm.  wide;  bractlets  linear-lanceolate,  about 
12  mm.  long,  1  mm.  wide;  calyx  scutellate  at  base,  deeply  and  nearly

regularly  5-parted,  1.5  cm.  long,  the  tube  4  mm.  long,  the  teeth 
12  mm.  long,  2  mm.  wide,  all  the  outer  surface  reddish  glandular- 
pruinose  pubescent;  corolla  strongly  constricted  above  stamen  in- 
sertion (this  about  7  mm.  above  the  base),  somewhat  incurved  and 
gradually  much  ampliate  to  the  throat,  the  upper  lip  biparted,  the 
lower  lobe  rounded-ovate,  glandular  pilose;  filaments  glabrous,  1  cm. 
long,  anthers  2  mm.  long;  ovary  ellipsoid,  glabrous  as  style,  this 
1  cm.  long,  the  2  distinctly  free  lobes  oblong,  canaliculate;  placentae 
sometimes  confluent  with  carpels;  capsule  1  cm.  long,  2-3-valved  to 
base;  seed  reticulation  conspicuous. — After  author,  who  compared 
the  species  to  the  Californian  0.  balbosa  Beck,  that  with  flowers 
scurfy,  1.5  cm.  long,  corolla  little  constricted,  less  ampliate  and  lobes 
all  elliptic,  acute;  Beck,  I.e.,  who  saw  only  imperfect  specimens,  posed 
the  question  without  decision;  the  Peruvian  plant,  if  intermediate 
forms  are  not  discovered,  may  be  a  stabilized  entity.

8:  185.  1922;  57. 

Stem  stout  and  branched  above  or  slenderly  from  the  little  in- 
crassate  base,  sparsely  squamate,  to  1.5  dm.  high,  glabrate  toward 
base,  early  densely  ferrugineous  glandular  pubescent  toward  apex, 
including  the  upper  part  of  the  corollas;  scales  broadly  triangular- 
ovate  (upper  ovate-lanceolate),  5  mm.  long;  bracts  lanceolate-ovate, 
to  1.5  cm.  long;  flowers  2.5  cm.  long,  the  upper  subsessile,  the  lower 
on  pedicels  to  1  cm.  long;  bractlets  linear-lanceolate,  obtuse,  about 
12  mm.  long,  2  mm.  wide,  adnate  below  to  the  funnelform  calyx,  its 
tube  7-8  mm.  long,  4-5  mm.  broad,  the  5  linear-lanceolate  subequal 
teeth  as  long,  2-2.5  mm.  wide;  corolla  little  constricted  above  stamen 
insertion  (this  6-7  mm.  above  base),  only  slightly  curved,  gradually 
ampliate,  the  upper  lip  parted  nearly  medially,  the  lobes  finally  re- 
curved, 2.8  mm.  wide,  rounded-ovate,  the  lower  lip  erect,  the  2  lateral 
lobes  ovate-oblong,  3.5  mm.  long,  2  mm.  wide,  the  medial  ovate, 
4  mm.  long,  glandular-pilose;  filaments  8  mm.  long,  hispidulous 
toward  base,  anthers  2  mm.  long;  ovary  ellipsoid-ovoid,  glabrous 
as  style,  this  7  mm.  long;  stigma  bilobed,  the  lobes  constricted, 
canaliculate;  placentae  free;  capsule  1  cm.  long,  4-5  mm.  thick, 
bivalved  to  base;  seeds  deeply  reticulate,  0.5  mm.  long,  0.2  mm. 
wide. — After  author;  some  species  in  the  genus  may  be  found  to  be 
based  on  tenuous  characters;  type  not  seen  by  Beck.
