i.    THE   JAMAICAN    SPECIES   OF    HERNANDIA 

On  March  20,  1908,  while  exploring  a  wooded  hill  near  Dol- 
phin Head  Mountain,  parish  of  Hanover,  in  the  western  part  of 
Jamaica,  in  company  with  Mr.  William  Harris,  we  observed  large 
trees  which  were  unknown  to  us  from  the  character  of  their  trunks, 
and  too  high  to  enable  us  to  determine  the  character  of  their  foli- 
age without  a  pair  of  field  glasses,  which  we  did  not  have  along  that 
day.  While  sitting  at  lunch  in  a  relatively  open  place  in  the  for- 
est, we  observed  the  top  of  one  of  these  trees,  some  30  meters 
high  and  at  least  a  meter  in  diameter,  against  the  sky  line,  and 
saw  that  it  was  covered  with  round  fruits,  some  of  which  we  found 
on  the  ground  under  this  tree,  and  realized  that  we  had  found  a 
very  interesting  species.  Our  negro  guide  felled  a  somewhat 
smaller  tree  with  his  machete,  and  thus  enabled  us  to  obtain  ex- 
cellent fruiting  herbarium  and  museum  specimens  of  the  Jamaican 
species  of  Hernandia. 

Up  to  this  time  the  tree  does  not  appear  to  have  been  definitely 
known  to  botanists  in  the  island  of  Jamaica.  Patrick  Browne 
(Civil  and  Natural  History  of  Jamaica,  ^Jl,  1756),  admits  the 
genus  and  remarks  :  "  This  tree  is  pretty  common  in  Barbadoes 
and  Mountserat,  and  grows  to  a  considerable  size  in  those  islands ; 
but  I  have  not  seen  any  in  Jamaica,  though  I  have  been  credibly 
informed  that  it  was  frequent  in  the  parish  of  Portland.  The  cups 
that  sustain  and  partly  invelop  the  nuts  are  very  large,  and,  as 
they  move  in  the  wind,  keep  a  whistling  noise,  which  is  often 
frightful  to  unwary  travellers.  The  seeds  are  very  oil)-."  Browne 
cites  Jack-in-a-Box  as  a  common  name. 

In  Flora  of  the  British  West  Indian  Islands,  page  285,  pub- 
lished in  i860,  Grisebach  does  not  attribute  the  tree  to  Jamaica  at 
all,  thus  indicating  that  no  specimens  of  it  were  extant  at  that 
time,  but  Meissner,  in  DeCandolle's  Prodromus  (151  :  263.  1864), 

337 


338  Britton  :    Studies  of  West  Indian  plants 

does  credit  it  to  Jamaica,  and  cites  P.  Browne,  although,  as  lie 
omits  an  exclamation  mark,  it  is  evident  that  he  did  not  see  a 
specimen,  nor  does  his  herbarium,  now  at  the  New  York  Botan- 
ical Garden,  contain  any  Her'nandia  from  Jamaica  ;  Meissner  re- 
fers the  record  of  P.  Browne  to  the  species  Hcrnandia  sonora  L., 
native  of  the  Windward  Islands  and  Porto  Rico,  and  perhaps  also 
of  the  East  Indies. 

Hcrnandia  sonora  is  readily  distinguishable  from  the  other  spe- 
cies by  its  peltate,  long-pointed  leaves,  and  the  only  other  West 
Indian  species  known  is  the  Cuban  Hcrnandia  cubcnsis  Griseb., 
which  has  narrow  long-acuminate  leaves.  Under  H.  sonora, 
Meissner  (DC.  Prodr.  264)  notes  a  variety  gnadelonpensis  from 
Guadeloupe  Island,  which  has  leaves  rounded  at  the  apex  and 
base,  or  slightly  cordate.  It  is  possible  but  not  probable  that 
this  is  the  same  as  the  Jamaican  tree,  but  the  description  is  insuf- 
ficient to  make  this  certain.  In  any  event,  the  Jamaican  tree  is 
evidently  specifically  distinct  from  either  H.  sonora,  or  H.  cnbensis. 
There  is  a  species  of  Hcrnandia,  H.  gidancnsis,  in  French  Guiana, 
but  not  much  is  known  of  it  other  than  the  plate  of  Aublet,  PI. 
Guian.  //.  32Q,  which  shows  that  this  must  be  quite  different  from 
the  plant  here  to  be  described. 

Hernandia  jamaicensis  Britton  &  Harris 

A  tree  30  m.  high  or  less,  with  spreading  and  ascending  stout 
branches,  the  trunk  becoming  at  least  a  meter  in  diameter,  the 
young  twigs  more  or  less  flattened  and  angled.  Leaves  subcori- 
aceous,  sometimes  2.5  dm.  long  ;  petioles  stout,  somewhat  shorter 
than  the  blade,  but  sometimes  1  dm.  in  length,  the  blades  elliptic 
to  elliptic-obovate,  obtuse  at  the  apex,  obtuse  or  subcuneate  at  the 
base,  3-nerved  or  faintly  5-nerved,  not  at  all  peltate  ;  inflorescence 
as  long  as  the  leaves  or  longer,  racemose  or  racemose-paniculate  ; 
calyx  of  the  pistillate  flowers  turbinate,  about  5  mm.  long,  its 
margin  truncate  ;  fruiting  calyx  subglobose,  yellow,  fleshy,  3—4 
cm.  long  and  about  as  thick  as  long,  its  wall  about  I  mm.  thick, 
its  orifice  1.5-2  cm.  wide  with  a  slightly  raised  margin  ;  drupe 
ovoid,  nearly  2  cm.  long,  1.5  cm.  in  diameter,  rounded  at  the 
base,  bluntly  pointed,  bluntly  8-ribbed  and  rugose  between  the  ribs. 

On  wooded  hill,  at  about  400  meters  altitude,  near  Dolphin 
Head,  Jamaica  [Britton  2321,  type;  Harris  10J12);  Woodstock, 
Westmoreland,  Jamaica  (Harris  9835).

2.    THE  GENUS  CASSIPOUREA  IN  JAMAICA 

Cassipourea  was  proposed  by  Aublet  (Hist.  PI.  Guian.  i:  528) 
in  1775  for  a  tree  of  French  Guiana,  his  Cassipourea  guianensis 
being  the  type  of  the  genus.  Svvartz  (Prodr.  84)  published  the 
generic  name  Lcgnotis,  including  in  it  two  species,  L.  elliptica 
from  Jamaica  and  L.  Cassipourea,  based  on  Aublet's  Cassipourea 
guianensis  ;  he  assigns  no  reason  why  his  name  thus  published  in 
1788  should  replace  Aublet's  Cassipourea  of  1775.  Poiret  (Lam. 
Encycl.  Suppl.  2:  131)  properly  adopted  the  older  generic  name 
and  transferred  the  Legnotis  clliptiea  of  Swartz  to  it.  A  number 
of  additional  species  from  tropical  America  and  Africa  have  since 
been  added  by  several  authors,  including  Cassipourea  alba  Griseb. 
from  the  island  of  Dominica.  That  Cassipourea  Aublet  and  Leg- 
notis Swartz  are  the  same  genus  seems  evident  from  an  examina- 
tion of  specimens. 

Cassipourea  elliptica  (Sw.)  Poir.  is  a  shrub  or  small  tree,  some- 
times reaching  6  meters  in  height,  and  grows  in  Jamaica  on  rocky 
wooded  hillsides.  Its  elliptic  long-pointed  leaves  are  as  brilliantly 
shining  as  those  of  any  plant  known  to  me,  and  individuals  seen 
in  contrast  to  the  duller  luster  of  other  trees  and  shrubs  stand  out 
as  most  striking  elements  in  the  landscape.  Mr.  Harris,  Dr.  Hol- 
lick,  and  I,  while  botanizing  near  Kempshot,  at  an  altitude  of 
about  500  meters  in  the  parish  of  St.  James,  western  Jamaica,  on 
March  23,  1908,  had  our  first  opportunity  of  studying  this  won- 
derfully beautiful  plant  in  the  field,  and  were  fortunate  enough  to 
see  its  bright  white  flowers  with  strikingly  laciniate  petals,  and  it 
was  an  experience  long  to  be  remembered.  The  lustrous  leaves 
and  pediceled  flowers  distinguish  Cassipourea  elliptica  from  the  two 
species  to  be  described  below.  A  remarkable  feature  of  an  indi- 
vidual tree  found  by  us  near  Kempshot  on  March  24,  1908,  is  the 
development  of  the  lower  branches,  which  droop  ami  bear  leaves 
not  more  than  one  half  the  size  of  those  on  the  flowering  branches 
above,  the  twigs  of  these  drooping  branches  being  very  slender 
and  repeatedly  forked.  We  preserved  herbarium  specimens  of  this 
curious  bud-sport ;  if  cuttings  from  such  a  branch  could  be  prop- 
agated, they  would  doubtless  yield  a  weeping  Cassipourea.

The  distinguishing  characters  of  the  three  Jamaica  species  are 
indicated  by  the  following  key  : 

Pedicels  as  long  as  the  calyx   or  longer;  leaves  brilliantly   shining.  I.    C.  elliptica. 
Pedicels  much  shorter  than  the  calyx,  or  scarcely  at  all  developed; 
leaves  dull  or  faintly  shining. 
Leaves  elliptic-lanceolate,  narrowed  at    the  base,   the  petioles 

about  as  long  as  the  calyx.  2.    C.  subsessilis.

together  in  the  axils,  very  nearly  sessile ;  calyx  tube  obconic,  2. 5 
mm.  long,  the  lobes  ovate,  obtusish,  about  as  long  as  the  tube, 
petals  white,  fimbriate. 

Along  a  brook,  Troy,  Jamaica  {Britton  488,  type)  ;  collected 
also  by  Mr.  Harris  at  the  same  place  (no.  0466).

3.    THE  GENUS  TEREBINTHUS  P.   BR.   IX 
THE  WEST  INDIES 

The  type  species  of  Terebinthus  P.  Br.  is  Pistacia  Simaruba  L., 
commonly  known  as  the  West  Indian  birch.  A  subsequent  name 
for  the  genus  is  Bitrscra  Jacq.  but,  as  shown  by  Dr.  J.  N.  Rose 
(Contr.  U.  S.  Nat.  Herb.  10  :  118),  this  name  is  unavailable,  because 
Terebinthus  has  priority.  Seven  species  are  known  to  me  from  the 
West  Indies,  two  of  them  here  to  be  described  as  new  ;  the  Mexi- 
can species  have  been  listed  by  Dr.  Rose. 

Leaflets  broad,  ovate,  elliptic,  or  obovate. 

Leaflets  3—1 1 ,  ovate,  acuminate  or  acute. 

Leaflets  thin  ;  bark  exfoliating  in  thin  layers.  I.    T.  Simaruba. 

Leaflets  coriaceous  ;  bark  close.  2.    T.  Hollickii. 

Leaflets  only  I,  obovate  to  elliptic,  obtuse.  3.    T.  simplicifolia. 

Leaflets  narrow,  oblong  to  lanceolate  or  oblanceolate. 

Leaflets  obtuse  at  the  base.  4.    T.  glattca. 

Leaflets  acute  at  the  base. 

Inflorescence  elongated,  sometimes  as  long  as  the  leaves.

Most  of  the  Jamaica  trees  have  pubescent  twigs  and  leaf-rach- 
ises  ;  this  hairy  race  is  evidently  the  typical  one,  based  by  Linnaeus 
on  Sloane,  pi.  199. 

2.  Terebinthus  Hollickii  sp.  nov 

A  tree  6  m.  high,  with  trunk  2.5  dm.  in  diameter,  its  bark  about 
8  mm.  thick,  reddish-gray  outside,  red  inside,  close,  not  peeling 
off  in  papery  layers.      Young  twigs  stout,  pubescent  ;   leaves  8-12

cm.  long,  clustered  at  the  ends  of  the  twigs  ;  rachis  pubescent  with 
spreading  hairs;  leaflets  3-7,  coriaceous,  ovate  3-6  cm.  long,  1.5 
-3  cm.  wide,  entire-margined,  obliquely  rounded  at  the  base,  short- 
acuminate  at  the  apex,  glabrous  or  very  nearly  so  when  old,  very 
inconspicuously  veined  above,  rather  prominently  veined  beneath  ; 
petiolules  stout,  3-5  mm.  long  ;  fruiting  inflorescence  4-7  cm. 
long,  the  raceme  simple  or  slightly  compound,  its  axis  pubescent ; 
fruits  8-10  mm.  long,  about  7  mm.  thick,  bluntly  triangular,  on 
stout  pedicels  4  or  5  mm.  long  ;  seed  sharply  3-angled. 

Dry  rocky  hillside,  Fort  Henderson,  Kingston  Harbor,  Ja- 
maica (N.  L.  Britton  &  Arthur  Hollick,  March  2,  1908,  no.  1816). 

3.  Terebinthus  simplicifolia  (DC.) 

Bursera  simplicifolia  DC.  Prodr.  2  :  78.      182?. 

Frequent  on  dry  hillsides  near  the  southern  coast  of  Jamaica,

7.  Terebinthus  Nashii  sp.  nov. 

A  tree  about  3  m.  high  with  nearly  smooth  terete  twigs, 
glabrous  throughout.  Leaves  I— 3-foliolate,  the  slender  petiole 
5—15  mm.  long,  somewhat  glaucous;  leaflets  linear-oblong,  nar- 
rowed at  the  base,  obtuse  or  acutish  and  mucronulate  at  the  apex, 
3—5  cm.  long,  1-1.5  cm.  wide,  pale  green,  very  indistinctly  veined 
on  both  sides,  chartaceous ;  fruiting  inflorescence  short,  few- 
fruited,  2  cm.  long  or  less  ;  fruits  6—j  mm.  long,  nearly  as  thick 
as  long,  borne  on  short  stalks,  2-5  mm.  long,  the  calyx  persistent 
at  their  bases.

4.    PASSIFLORA  CILIATA  Ait. 

This  species  was  described  in  1789  (Hort.  Kew.  I  :  310)  from 
plants  cultivated  by  Mrs.  Norman,  who  introduced  it  into  England 
from  Jamaica  in  that  year.  In  the  Botanical  Magazine,  plate  288, 
published  January  1st,  1795,  Curtis  remarks  that  he  saw  it  during 
the  latter  part  of  the  preceding  summer  with  great  profusion  of 
flowers  in  several  collections,  and  the  figure  given  by  him  at  this 
place  was  made  from  a  plant  in  the  collection  of  Mr.  Vere. 

This  beautiful  passion-flower  seems  to  have  been  much  mis- 
understood by  subsequent  botanists.  It  appears  to  be  confined 
naturally  to  the  island  of  Jamaica,  where  Mrs.  Britton  found  it  in 
March,  1908,  in  quantities  along  roadsides  through  the  hills  near 
Bulstrode,  parish  of  Westmoreland,  growing  with  P.  foetida. 

The  plant  has  been  supposed  to  be  a  variety  of  P.  foetida,  and 
has  been  so  ranked  by  a  number  of  authors.  Grisebach,  in  Flora 
of  the  British  West  Indies,  however,  regarded  it  as  specifically  dis- 
tinct, but  apparently  erred  in  attributing  it  to  the  Bahamas  as  well 
as  to  Jamaica.  It  has  not  been  found  in  the  Bahamas  during  any 
of  our  extensive  explorations  of  that  archipelago.  So  far  as  one 
can  see,  Grisebach  was  quite  justified  in  maintaining  it  as  a  species 
distinct  from  P.  foetida. 

5.  BIDENS  PILOSA  L. 

This  species  was  founded  by  Linnaeus  (Sp.  PI.  832)  in  1753  on 
the  "  Bidens  latifolia  hirsutior  semine  angustiore  radiato  "  of  Dil- 
lenius  Hort.  Eltham.  51.  pi.  4.3.  f.51.  The  name  has  since  been 
used  by  many  authors  for  a  very  common  and  well-known  tropical 
weed  and  often  with  the  remark  that  it  is  not  pilose.  Dr.  Gray 
surmised  that  the  figure  of  Dillenius  might  really  have  been  made 
from  a  plant  of/?,  frondosa.  During  repeated  trips  to  the  West 
Indies  I  have  looked  closely  at  a  great  many  individuals  of  this 
weedy  plant  but  never  could  find  any  pilose  ones  until  this  spring  ; 
the  species  is  usually  almost  or  quite  without  trichomes.  But  at 
Moneague,  Parish  of  St.  Ann's,  Jamaica,  in  April,  1908,  I  noticed 


344  Britton  :    Studies  of  West  Indian  plants 

with  great  interest  a  roadside  ditch  full  of  these  plants,  some 
densely  pilose  all  over,  some  essentially  glabrous.  I  could  not 
see  at  the  time  of  collecting  nor  have  I  been  able  to  see  from 
further  study  of  the  dried  specimens,  any  other  difference  what- 
ever in  the  two  races.  Both  arc  rayless,  have  identical  achenes 
varying  from  2  to  4,  with  awns  relatively  of  the  same  length, 
leaves  of  the  same  shape  and  texture  and  involucral  scales  alike 
From  the  environment  and  occurrence  there  was  nothing  to  pre- 
vent one  coming  from  the  seeds  of  the  other.  The  plants  as  here 
observed  are  not  as  stout  nor  as  large-leaved  as  the  figure  of  Dil- 
lenius.  The  typical  race  of  Bidens  pilosa  L.  is  then  well  named, 
but  it  is  apparently  rare. 

Bidens  laicantlia  (L.)  Willd.  published  by  Linnaeus  as  Coreop- 
sis leucantlia  (Sp.  PI.  ed.  2.  1282),  also  a  very  common  tropical 
weed,  has  sometimes  been  regarded  as  a  variety  of  B.  pilosa.  It 
has  white  rays  often  1.5  cm.  long,  and  in  life  appears  very  different, 
but  herbarium  specimens  from  which  the  rays  have  fallen  are 
often  difficult  to  place.  It  commonly  grows  with  the  glabrous  B. 
pilosa,  but  perhaps  more  frequently  in  separate  patches  and  in  the 
West  Indies  one  frequently  sees  large  areas  inhabited  by  the  one 
to  the  exclusion  of  the  other.  At  Kempshot,  near  Montego 
Bay,  Jamaica,  they  grew  together  in  a  small  garden  and  I  was 
able  to  study  them  side  by  side  ;  here  B.  leucantha  had  the  invo- 
lucral scales  spreading  at  flowering  time,  while  those  of  the  glab- 
rous B.  pilosa  were  erect.  I  am  inclined  to  regard  'leucantha  as  a 
distinct  species.      There  is  a  race  with  undivided  leaves. 

6.  THE  GENUS  MALACHE  B.  VOGEL. 

Malaclie  scabra  was  proposed  by  B.  Vogel  (Trew,  PI.  Select. 
50.  pi.  90.  1772)  as  the  name  of  a  mangrove-swamp  shrub 
common  nearly  throughout  the  West  Indian  region,  subsequently 
called  by  Cavanilles  (Diss.  3:  136.  pi.  46.  f.  1.  1787)  Pavonia 
spicata,  and  by  Swartz  (Fl.  Ind.  Occ.  2:  121  5.  1800)  Pavonia 
racenwsa.  Trew  cites  pre-Linnaean  names  for  the  plant,  and  gives 
a  detailed  description  and  a  beautiful  illustration  of  it,  especially 
referring  to  Sloane,  Hist.  Jam.  221.  pi.  ijp.  f.  2 ;  Sloane's  de- 
scription and  illustration  are  unmistakable  for  the  species.  Lin- 
naeus does  not  appear  to  have  had  any  name  for  it. 


Brittox  :    Studies  of  West  Indian  plants  345 

Pavonia  Cav.  has  as  its  type  species  P.  spinifex  Cav.  After 
studying  quantities  of  this  and  of  Malache  scabra,  both  in  the  field 
and  in  the  herbarium,  I  am  confident  that  they  should  not  be 
included  in  the  same  genus,  inasmuch  as  they  differ  too  widely  in 
the  floral  and  fruit-structure  and  in  habit ;  only  the  most  artificial 
classification  can  retain  them  as  congeneric. 

Malache  scabra  is  a  typical  shrub  of  coastal  swamps  from 
Florida  southward  through  the  Caribbean  region  to  Central 
America,  Colombia,  Trinidad,  and  Brazil,  and  is  recorded  as  grow- 
ing as  far  south  as  Peru  on  the  western  side  of  South  America. 

Having  seen  much  of  this  species  along  mangrove  swamps, 
nearly  or  quite  always  within  the  tidal  influence  at  high  water,  I 
was  surprised  and  interested  while  exploring  the  high  rocky 
"  Cockpit  Country"  of  Jamaica  with  Air.  William  Harris  in  Sep- 
tember, 1907,  to  find  a  similar  plant  on  hills  in  wet  woods  in  the 
vicinity  of  Troy,  reaching  altitudes  of  at  least  600  meters.  Mr. 
Harris  had  collected  fruiting  specimens  of  it  the  year  before,  and 
had  noticed  its  resemblance  to  the  coastal  shrub  ;  Professor  Urban 
has  recently  described  it  from  these  specimens  [Harris  P4S7),  as 
Pavonia  racemosa  var.  troyana  (Symb.  Ant.  5:  530.  1908).  I 
obtained  additional  specimens  both  in  flower  and  fruit  in  1907 
{Britton  515)  and  from  field  studies  made  then  in  comparison  with 
Malache  scabra  I  am  convinced  that  this  "Cockpit  Country" 
plant  is  specifically  distinct,  and  to  be  called  Malache  troyana  ; 
it  has  broader  involucral  bracts,  much  broader  and  differently 
shaped  carpels,  the  anther-bearing  part  of  the  stamen-column  pro- 
portionately shorter,  and  the  fruiting  peduncles  are  shorter  and 
stouter.  The  plant  is  tall  and  slender  and  sometimes  approaches 
the  form  of  a  small  tree  up  to  4  or  5  meters  high.

7.   HARRISIA,  A  NEW  GENUS  OF   CACTACEAE 

Night-flowering  cacti  with  slender  upright  branched  cylindric 
stems,  the  branches  fluted,  with  from  8  to  1 1  rounded  ribs,  sepa- 
rated by  shallow  grooves  and  bearing  areoles  at  frequent  intervals, 
each  areole  with  several  acicular  spines.  Flowers  borne  singly, 
at  areoles  near  the  ends  of  the  branches,  funnelform,  large,  with  a 
cylindric  scaly  but  spineless  tube  as  long  as  the  limb  or  longer  ; 
buds  globose,  ovoid  or  obovoid,  densely  scaled,  the  scales  bearing 
long  or  short  woolly  hairs  ;  sepals  pink  or  greenish,  linear-lanceo- 
late ;  petals  white  ;  stamens  shorter  than  the  petals,  style  some- 
what longer  than  the  stamens  ;  fruit  globose  to  ovoid-globose, 
green  to  yellow,  spineless  but  with  deciduous  scales,  the  corolla 
withering-persistent ;  seeds  very  numerous,  small. 

The  genus  is  named  in  honor  of  William  Harris,  Superintendent 
of  Public  Gardens  and  Plantations  of  Jamaica,  distinguished  for  his 
contributions  to  the  knowledge  of  the  flora  of  that  island.  The 
descriptions  are  drawn  up  mainly  from  field  observations  and  from 
living  plants  in  the  collections  of  the  New  York  Botanical  Garden. 

Bud-scales  densely  covered  with  hairs  I  — 1 . 5  cm.  long. 

Hairs  bright  white  ;    areoles  2.5-3   crn-    aPart  ;    spines  6-9,

the  longer  ones  2-2.5  cm.  long  ;  bud  ovoid,  prominently  long- 
pointed,  its  scales  with  few  curled  white  hairs  7-  10  mm.  long  ; 
fruit  yellowish,  ellipsoid,  about  8  cm.  long,  5-6  cm.  thick,  rounded 
at  both  ends,  the  tubercles  very  low,  with  tips  only  1.5  mm.  high. 

Description  from  N.  Y.  B.  G.  no.  261-f,  collected  at  George- 
town, Long  Island,  Bahamas,  by  N.  L.  Britton  and  C.  F.  Mills- 
paugh,  in  1907  (no.  6jjy).  Named  in  honor  of  Hon.  Herbert 
A.  Brook,  Registrar  of  the  Bahamas,  in  recognition  of  his  valuable 
aid  in  our  exploration  of  these  islands. 

The  plant  of  Florida,  of  which  I  do  not  yet  know  the  buds 
or  the  flowers,  more  closely  resembles  this  Bahamian  species 
in  its  spines  and  areoles  than  it  does  any  of  the  others  here  de- 
scribed. Our  living  plant,  N.  Y.  B.  G.  no.  icjpoo,  was  collected 
by  Prof.  P.  H.  Rolfs  on  islands  east  of  Malabar  and  brought  to 
the  Garden  by  Dr.  J.  K.  Small  in  1903.  As  shown  by  an  her- 
barium specimen,  prepared  by  Dr.  Small  at  that  time  (no.  yS),  the 
fruit  of  this  species  is  nearly  globular,  about  5  cm.  in  diameter, 
and  apparently  smooth  or  nearly  so.  We  also  have  an  excellent 
photograph,  taken  by  Mr.  C.  L.  Pollard  on  Key  Largo  ;  and  Cur- 
tiss'  N.  A.  Plants  no.  g6j,  from  a  locality  between  the  Indian 
River  and  the  ocean,  is  this  same  species,  which  is  described  in 
Chapman's  Southern  Flora,  at  least  in  so  far  as  the  flower  is  con- 
cerned, under  the  name  Cerens  monoclonos,  but  it  is  not  C.  mono- 
clonos  of  De  Candolle. 

8.  Harrisia  Taylori  sp.  no  v. 

Plant  light  green,  branched  above,  1.5-2  m.  high,  the  branches 
divaricate-ascending,  rather  stout,  4  or  5  cm.  thick,  9-ribbed,  the 
ribs  rounded,  the  depressions  between  them  rather  deep.  Areoles 
2-3  cm.  apart;  spines  9-12,  the  longer  3-5  cm.  long,  ascending; 
bud  globose-ovoid,  short-pointed,  its  scales  with  sparse  curled 
grayish-white  wool  $—6  mm.  long. 

Description  from  N.  Y.  B.  G.  no.  2jj6j,  collected  by  Norman 
Taylor  on  the  sea-beach  between  Rio  Grande  and  Rio  Ubero,  in 
in  eastern  Cuba,  in  1906  (no.  2jj).

Illustration  :  Plumier,  PI.  Amer.  ed.  Burmann,  pi.  /pj. 

Known  only  from  Plumier's  description  and  illustration  ;  it 
may  belong  to  the  genus  Harrisia,  —  although  the  long-exserted 
style  seems  to  preclude  it.

Referred  in  synonymy  by  Schumann  to  Cereits  repandus,  that  is 
to  say,  presumably  a  Harrisia.     Known  only  from  the  description. 

Cereus  repandus  L.,  originally  from  Curacao,  is,  from  the 
description,  presumably  a  Cephaloeereus.

Potomorplie  umbelleita  Miq.  Comm.  Phyt.  31.     1838. 

Field  observations  in  Jamaica  demonstrate  that  the  two  supposed 
species  of  Potomorplie  are  not  distinct.  The  difference  of  peltate 
and  non-peltate  leaves  depended  upon  by  Linnaeus  and  most  sub- 
sequent authors  who  have  had  occasion  to  describe  these  plants, 
including  M.  Casimir  de  Candolle  (in  Urban,  Symb.  Ant.  3  :  208 
—211),  is  worthless,  because  individual  plants  bear  both  kinds  of 
leaves.  I  had  long  suspected  this  to  be  the  case,  and  while  discussing 
the  matter  with  Mr.  William  Harris  on  the  road  from  Bath  to  Cuna 
Cuna  Gap  last  September,  where  specimens  of  both  supposed  species 
were  abundant,  he  almost  immediately  detected  a  plant  which  bore 
peltate  leaves  at  its  upper  nodes  and  non-peltate  leaves  at  the  lower 
ones,  and  we  found  a  plenty  of  such  specimens  afterwards  {Britton 
3j 13).  The  relative  number  of  spikes,  which  also  has  been  supposed 
to  differentiate  the  species,  I  had  previously  found  to  be  quite  incon- 
stant, and  the  character  of  pubescence  used  in  the  descriptions  by 
M.  de  Candolle  is  also  inconstant,  as  evidenced  by  his  proposing  a 
hairy  variety  of  P.  peltata  (Joe.  cit.  210,  as  Piper  peltatum  hirtel- 
lum  C.  DC). 

M.  de  Candolle  includes  the  species  in  the  genus  Piper,  and 
describes  them  as  shrubs  up  to  4  meters  high.  As  a  matter  of 
fact,  the  plant  is   not  properly  a   shrub,  its  stems  being  soft,  not 


Britton  :    Studies  of  West  Indian  plan  .r,i;7 

.appreciably  woody ;  his  principal  character  to  distinguish  Piper  from 
Peperomia  is  that  Piper  consists  of  shrubs  and  trees  and  Peperomia 
of  herbs  ;  P.  peltata  should  then  be  excluded  from  Piper,  and  as 
it  has  distinct  habital  characteristics,  differing  widely  from  any  true 
Pipers  or  Peperomias,  I  think  it  better  regarded  as  a  distinct  genus 
under  Miquel's  name  PotomoipJic.  Kunth,  and  also  A.  Dietrich, 
allowed  it  in  Peperomia. 

9.  THE  GENUS  STEGNOSPERMA  BENTH. 

Stegnosperma  was  established  by  Bentham  (Bot.  Voy.  Sulphur 
17.  pi.  12.  1844)  with  the  single  species  6".  halimifolium  Benth. 
from  Cape  St.  Lucas,  Lower  California.  The  next  year,  A.  Richard 
(Ess.  Fl.  Cub.  632.  1845)  proposed  an  additional  species,  S. 
cnbense  A.  Rich,  from  Cuba.  Moquin  (in  DC.  Prodr.  132 :  36. 
1849)  makes  no  mention  of  the  Cuban  plant,  though  recording  it 
from  Guatemala,  but  in  Bentham  and  Hooker  (Genera  Plantarum 
3  :  86.  1880)  the  two  supposed  species  are  regarded  as  one,  and 
its  range  extended  to  Santo  Domingo. 

The  range  is  now  extended  to  Jamaica,  where  the  plant  was 
found  by  us  in  the  Healthshire  Hills,  an  exceedingly  dry  region 
at  about  100  meters  elevation,  south  of  Spanish  Town  {Britton  & 
Harris  10322  ;  Britton  3062) ;  here  it  is  a  woody  vine  8  m.  long, 
climbing  to  the  tops  of  low  trees  ;  its  reddish  fleshy  fruits  are  3- 
grooved,  borne  in  short  terminal  racemes.  The  Mexican  and 
Central  American  plant  seems  to  me  to  be  specifically  identical 
with  that  of  the  West  Indies,  as  maintained  by  Bentham  and  also 
bv  Heimerl  in  "  Die  natiirlichen  Pflanzenfamilien." 

10.    UNDESCRIBED  SPECIES  FROM  JAMAICA 
Dorstenia  jamaicensis  Britton,  sp.  nov.

Leaves  2-3  dm.  long  ;  petiole  1.5-2.5  cm.  long;  leaflets  5-9, 
flat,  thin,  oblong-lanceolate  to  ovate-elliptic,  faintly  pinnately 
veined  with  about  1  5  veins  on  each  side  of  the  midrib,  narrowed 
or  rounded  and  somewhat  oblique  at  the  base,  rather  long-acumi- 
nate at  the  apex,  the  larger  ones  10-16  cm.  long,  4-7.5  cm. 
wide  ;  petioles  5-8  mm.  long  ;  fruiting  panicles  1 5  cm.  long  or 
less,  its  branches  finely  appressed-pubescent ;  fruiting  pedicels 
stout,  2—3  mm.  long;  capsule  globose  to  oval,  1-2.5  cm-  l°ng> 
blunt  or  pointed,  rugose,  densely  velutinous,  tardily  dehiscent.

11.     ADDITIONS  TO  THE  LIST  OF  JAMAICA  SEDGES 

In  1907  I  contributed  an  enumeration  of  the  sedges  of  Jamaica 
to  the  Bulletin  of  the  Jamaica  Department  of  Agriculture  (5  : 
Supplement  1).  Further  exploration  of  that  island  in  the  autumn 
of  1907  and  in  the  spring  and  autumn  of  1908  has  disclosed  the 
occurrence  of  some  additional  species  and  the  habitat  of  others 
which  were  recorded  by  me  from  the  statements  of  other  botanists.

North  American  Cyperus  tctragonus  Ell.  from  Jamaica,  and  in  re- 
ferring C.  anceps  to  it  as  a  synonym,  but  abundant  material  now 
convinces  me  that  the  species  are  distinct.  This  sedge  is  plentiful 
on  grassy  hillsides  and  banks  in  the  parish  of  Manchester  [Britton

where  the  generic  name  is  printed  Comocladia.  Browne  refers 
to  Sloane's  description  and  figure  of  "Primus  racemosa,  caudice 
non  ramosa"  (Hist.  Jam.  2:  131.  pi.  222.  f.  1);  the  illustration 
there  given  is  not  wholly  satisfactory  for  the  plant  which  has  been 
taken  for  this  species,  but  which  is  here  accepted  as  usually 
interpreted. 

Distributiox:  Moist  woodlands  at  middle  and  lower  eleva- 
tions throughout  Jamaica;  Haiti  and  Santo  Domingo. 

*The  spelling  of  the  generic  name  was  changed  by  Linnaeus  t.i  ( 'atnoi  ladia,  but 
this  form  is  here  regarded  as  a  typographical  error,  although  it  was  continued  by 
Linnaeus,  in  the  second  edition  of  Species  Plantarum,  and   in  suco  litions  of 

the  Systema,  but  was  changed  back  to  the  original  by  Gmi  t.  ed.  [3.      1 

The  original  spelling  was  accepted  by  Jacquin,  by  Swartz.  and  by  most  subsequent 
authors.

Type  locality:  Cuba  [Rugel  277,  the  type  specimen,  is  from 
Matanzas]. 

Distribution:  Cuba,  at  lower  altitudes,  provinces  of  Oriente, 
Camagiiey,  Santa  Clara,  Matanzas,  and  Havana. 

Note. — Lower  leaflets  ovate,  the  others  mostly  oblong.  Engler

ovate,  long-stalked,  and  with  only  3  or  4  teeth  on  each  margin. 
The  number  of  teeth  is  often  9  on  each  margin.  The  species 
consists  of  a  number  of  races,  differing  in  width  of  leaflets,  length 
of  petiolules  and  number  of  teeth  on  the  leaf-margins,  the 
extremes  appearing  quite  different  from  each  other. 

A.   Richard    (in    Sagra,  Hist.  Cub.    10:   155.      1850)  remarks 


Brixton  :    Studies  of  West  Indian  plants  .".49 

as  follows  concerning  this  species,  which  was  subsequently  de- 
scribed by  Grisebach : 

"I  have  observed  an  example  of  this  tree,  but  without  flowers, 
which,  it  seems  to  me,  could  form,  if  not  a  distinct  species,  which 
I  am  not  far  from  believing,  at  least  a  very  notable  variety.  The 
leaflets  are  almost  as  large  as  the  leaves  of  the  'castafio,'  are  also 
rough  on  both  faces,  dentate  and  spine-like  in  their  contour;  and, 
in  short,  recall  in  all  their  shape  the  leaflets  of  Comocladia  dentata, 
but  are  much  larger  and  rougher.  If  the  opportunity  comes  to  see 
this  plant  with  flower  and  fruit  it  will  perhaps  be  possible  to  form 
a  distinct  species  to  which  the  name  Comocladia  platyphila*  will 
apply  perfectly."

base,  serrate  with  about  8  bristle-tipped  teeth  on  each  margin, 
the  veins  prominent  on  the  underside,  diverging  nearly  at  right 
angles  from  the  slender  midvein,  the  under  surface  paler  green 
than  the  upper ;  panicles  4  dm.  long,  glabrous,  slender,  their  branches

Field  observations  indicate  that  Comocladia  dentata  and  C. 
propinqua  can  not  be  held  as  distinct  species;  the  leaflets  vary 
from  narrowly  lanceolate  to  broadly  ovate,  and  from  sharply 
spinulose-dentate  to  nearly  or  quite  entire.  The  tree  becomes  6 
meters  high  in  Santa  Clara,  Cuba.

Hillsides  and  woodlands  in  moist  and  wet  districts,  at  middle 
and  higher  altitudes,  ascending  to  2300  meters  in  the  Blue  Moun- 
tains. 

The  species  apparently  consists  of  numerous  races,  differing 
in  the  amount  of  stellate  pubescence,  in  the  shape  of  the  fruit, 
and  in  the  length  of  the  stamens.  Very  densely  tomentose  bushes 
grow  in  proximity  to  slightly  pubescent  ones  about  Cinchona. 

2.  Viburnum  arboreum  sp.  nov.

branches.  Leaves  chartaceous,  entire,  oval-elliptic,  dull  green, 
glabrous  or  sparingly  stellate-pubescent  above,  loosely  stellate- 
pubescent  beneath,  8-12  cm.  long,  5-6.5  cm.  wide,  short-acumin- 
ate at  the  apex,  unequally  narrowed  or  obtuse  at  the  base,  the 
veins  about  6  on  each  side  of  the  midvein,  the  stout  petioles  stel- 
late-pubescent, 1-2  cm.  long,  inflorescence  stellate-pubescent, 
8-12  cm.  broad;  fruiting  pedicels  3  mm.  long  or  less;  fruit  oblong, 
9-10  mm.  long  and  3  mm.  thick  when  dry,  narrowed  at  both  ends, 
crowned  by  the  ovate  acute  ciliate  calyx-lobes  and  tipped  by 
the  base  of  the  style.

Mountains  of  Haiti  and  Santo  Domingo.  This  plant  is  rep- 
resented in  the  herbarium  of  the  New  York  Botanical  Garden  by 
the  following  specimens:  "In  montibus,  Hispaniola  (Jacquemont) ; 
Sierra  del  Palo  Quemado,  Santo  Domingo,  at  500  meters  (Eggers 
18  gf);  pineland,  Marmelade,  Haiti,  at  900  to  1100  meters  {Nash 
jig;   Nash  &  Taylor  13 12). 

Professor  Chodat  ignores  Badiera  Penaea  in  his  monograph, 
and  describes  Eggers  no.  iSgy  as  Poly  gala  domingensis ,  not  recog- 
nizing the  genus  Badiera.  Mr.  Nash's  no.  Jig,  which  is  in  young 
fruit,  so  closely  resembles  the  original  figure  of  Poly  gala  Penaea 
L.  (Plumier,  ed.  Burmann,  pi.  214.  f.  1)  that  it  appears  to  me 
the  two  supposed  species  must  be  one;  the  character  cited  by 
De  Candolle  (Prodr.  1:  335)  of  flowers  solitary  in  B.  Penaea 
and  flowers  racemose  in  B.  domingensis  is  doubtful;  the  Plumier 
figure  shows  the  plant  in  fruit,  and  in  this  as  in  other  species  of  the 
genus  often  only  one  flower  of  the  cluster  produces  fruit. 

2.  Badiera  virgata  sp.  nov. 

A  shrub  or  small  tree  up  to  4  meters  high,  the  branches  nearly 
erect,  densely  leafy,  the  twigs  finely  puberulent.  Leaves  obovate, 
or  obovate-oblanceolate,  rigid,  10  mm.  long  or  less,  4-8  mm.  wide, 
puberulent  or  minutely  papillose-puberulent,  or  becoming  nearly 
or  quite  glabrous  when  old,  rounded  at  the  apex,  or  some  of  them 
slightly  emarginate,  narrowed  at  the  base,  the  petioles  pubescent, 
1— 1 .5  mm.  long,  the  midvein  slightly  elevated  beneath,  the  lateral 
venation  wholly  obscure;  flowers  several  in  the  axillary  clusters 
or  solitary,  yellow-green,  2  mm.  long;  fruiting  pedicels  1.5  mm. 
long;  fruit  5  mm.  long,  the  lobes  narrowly  winged  (only  imperfect 
ones  with  one  lobe  developed  seen).

Thickets  in  dry  soil,  Oriente,  Camagiiey,  and  Santa  Clara, 
Cuba.  (Type,  Britton  2086,  from  United  States  Naval  Station, 
Guantanamo  Bay,  March  17-30,  1909.) 

3.  Badiera  oblongata  N.  L.  Britton,  Bull.  N.  Y.  Bot. 

Gard.  5:  314.      1907 

Distribution:  Bahama  Islands:  Andros,  New  Providence,  Cat 
Island,  Acklin's  Island,  Crooked  Island,  Watling's  Island,  Caicos 
Islands;  Cayo  Sabinal  and  mainland  of  Camagiiey,  Cuba  {Shafer 
878  1085,  977;  also  collected  in  Cuba  by  Wright,  no.  115  in  part). 

The  Cuban  specimens  here  referred  have  leaves  mostly  more 
obtuse  at  the  base  than  those  of  the  typical  Bahamian  plant,  but 
a  specimen  from  Andros  Island  {Small  &  Carter  8681)  seems  to 
be  identical  with  them. 

A  plant  from  the  palm  barren  at  Santa  Clara,  Cuba  {Britton 
&  Wilson  6066),  has  shorter  emarginate  leaves  12-20  mm.  long, 
with  the  midvein  deeply  impressed  above;  it  is  tentatively  re- 
ferred to  this  species.

Leaves  ovate  to  elliptic,  2.5-6  cm.  long,  1.5-3.5  cm-  wide, 
bluntly  acuminate  or  acute  at  the  apex,  cuneate-narrowed  or 
acute  at  the  base;  fruit  7.5-8.5  mm.  long,  10  mm.  wide,  lobed  to 
about  one  third,  the  lobes  rounded.

Wright  at  "La  Sabanilla"  and  distributed  under  this  same  number; 
Wright's  no.  3496  belongs  to  this  species,  and  also  part  of  his  115, 
collected  in  eastern  Cuba. 


Brittox  :    Studies  of  West  Indian  plants  363 

Professor  Chodat  indicates  this  Cuban  species  as  occurring 
also  in  Jamaica,  but  this  I  take  to  be  an  error. 

6.  Badiera  montana  sp.  nor. 

A  shrub,  3  m.  high,  the  twigs  densely  puberulent.  Leaves 
broadly  oval,  4-5  cm.  long,  2.5-3.5  cm-  wide,  firm  in  texture, 
quite  densely  puberulent  when  unfolding  and  sparingly  puberulent 
when  mature,  rounded  or  slightly  emarginate  at  the  apex,  acutish 
at  the  base,  dull  dark  green,  the  midvein  slightly  impressed  in  the 
upper  surface,  elevated  on  the  underside,  the  lateral  veins  few, 
slender,  the  rather  stout  puberulent  petioles  2-3  mm.  long;  in- 
florescence several-flowered;  bracts  ovate,  acute,  pubescent, 
about  0.5  mm.  long;  fruiting  pedicels  pubescent,  1.5-2  mm.  long; 
stipe  of  the  fruit  1  mm.  long;  fruit  8-10  mm.  long,  10-12  mm.  wide 
at  the  top,  puberulent,  lobed  to  about  one  fifth,  the  lobes  rounded- 
truncate. 

Rocky  wooded  hill,  Arroyo  Grande,  Trinidad  Mountains,  Cuba, 
at  about  700  meters  altitude  (Britton  &  Wilson  5461,  March  11, 
12,  1910). 

Differs  from  B.  cubensis  by  its  obtuse  leaves,  larger  and  longer 
fruit. 

7.  Badiera   Berteriana  Spreng.   Syst.   3:  172.     1826 

Described  as  with  oblong-lanceolate  obtuse  leaves  and  re- 
corded as  from  Hispaniola.  Professor  Chodat  does  not  refer  to 
this  species  in  his  monograph;  it  was  collected  by  Bertero  and 
called  by  him  Polygala  domingensis,  but  Sprengel's  description 
indicates  that  it  is  not  Polygala  domingensis  of  Jacquin,  here 
referred  to  Badiera  Penaea  (L.)  DC. 

Excluded  Species. 

Badiera  (?)  acuminata  (Willd.)  DC.  Prodr.  1:  335  is  Polvoala 
acuminata  Willd.  Sp.  PI.  3:  887,  native  of  Peru  and  Chile. 
Professor  Chodat  describes  it  as  new  in  his  monograph  (p.  46), 
but  the  name  dates  from  at  least  the  year  1805. 

Badiera  (?)  divaricata  DC.  Prodr.  1:  335,  from  Para,  South 
America  (presumably  Brazil),  was  not  taken  up  by  Mr.  A.  \Y. 
Bennett  in  the  Flora  Brasiliensis.

16.  DENDROPANAX  IN  THE  WEST  INDIES 

1.  Dendropanax  arboreum  (L.)  Dene.  &  Planch. 

A  tree,  up  to  20  m.  high,  but  usually  much  smaller  and  often 
flowering  as  a  shrub.  Leaves  chartaceous,  from  ovate  to  obovate, 
mostly  acuminate  at  the  apex,  narrowed  or  rounded  at  the  base, 
often  2  dm.  long;  inflorescence  from  shorter  than  the  leaves  to 
equaling  them,  or  longer,  the  20  umbels  or  fewer  racemosely 
arranged  and  umbellate  at  the  summit,  sometimes  leafy-bracted, 
but  the  bracts  usually  small,  ovate  to  lanceolate;  peduncles  of 
the  umbels  slender,  ascending,  up  to  3  cm.  long  in  fruit;  pedicels 
1 3^  to  3  times  as  long  as  the  flowers,  somewhat  elongating  in 
fruit;  petals  white  or  greenish ;  calyx  rather  sharply  toothed,  about 
2  mm.  wide  at  flowering  time;  fruit  black,  strongly  lobed,  6-8  mm. 
thick. 

Widely  distributed  at  lower  and  middle  altitudes  in  moist 
or  wet  districts  in  Jamaica,  Cuba,  Hispaniola,  Porto  Rico,  and 
on  Signal  Hill,  St.  Thomas.     Ascends  to  1,600  meters  in  Jamaica. 

2.  Dendropanax  samydifolium  (C.  Wright)  Seem. 
This  species  is  known  to  me  only  from  the  original  specimens 

collected  by  Wright  at  S.  Felepina  near  La  Grifa,  western  Cuba; 
Wright's  description  calls  for  a  tree  up  to  13  meters  high.  The 
leaf  base  is  decurrent  on  the  petiole.  The  species  seems  very 
closely  related  to  D.  arboreum,  which  is  abundant  in  the  mountains 
and  hills  of  western  Cuba.

Gilibertia  brachypoda  Urban,  Symb.  Ant.  5:  452.     1908. 

A  short-pctioled  and  long-pediceled  Haitian  mountain  species, 
related  to  D.  arboreum,  known  to  me  only  from  Professor  Urban's 
description. 

4.    Dendropanax  laurifolium  (E.  March.)  R.  C.  Schneider 

A  detailed  description  of  this  endemic  Porto  Rico  mountain 

tree  is  published  by  Professor  Urban  in  Symbolae  Antillanae  1 : 

203. 

5.    Dendropanax  cuneifolium  (C.  Wright)  Seem. 

A  shrub  or  tree  up  to  6  m.  high,  the  branches  slender,  often 
drooping.  Leaves  spatulate  to  oblong-oblanceolate,  2  dm.  long 
or  less,  1.5-6  cm.  wide,  obtuse,  or  bluntly  acute  at  the  apex, 
cuneate  at  the  base,  the  petiole  1/6  to  1/4  the  length  of  the  blade; 
peduncle  slender,  straight,  as  long  as  the  leaves  or  longer;  umbel 
7-20-flowered ;  pedicels  1.5-2  cm.  long;  petals  green,  acute;  flower- 
ing calyx  about  4  mm.  broad;  fruit  globose  to  globose-oblong, 
black,  6-8  mm.  thick,  the  persistent  style  about  half  its  length. 

Banks  of  streams  and  wooded  bogs  at  lower  and  middle  eleva- 
tions, Pinar  del  Rio  and  Isle  of  Pines,  Cuba. 

6.  Dendropanax  nutans  (Sw.)  Dene.  &  Planch. 

A  shrub  with  stout  gray  branches.  Leaves  ovate  to  ovate- 
elliptic,  coriaceous,  10  cm.  long  or  less,  acute  or  short-acuminate  at 
the  apex,  narrowed  or  rounded  at  the  base,  the  veins  rather 
prominent  on  the  under  side,  the  stout  petioles  very  unequal  in 
length,  sometimes  two  thirds  as  long  as  the  blade;  peduncle 
stout,  5-7  cm.  long,  bracted  at  or  near  the  base;  umbels  many- 
flowered,  inclined  or  nodding;  pedicels  2-3  cm.  long;  flowering 
calyx  5  mm.  broad. 

Known  only  from  Blue  Mountain  Peak,  Jamaica,  where  it  is 
reported  as  abundant.  Professor  Urban  (Symb.  Ant.  1 :  200) 
characterizes  the  umbel  as  strictly  erect,  but  it  is  inclined  or 
nodding  in  all  specimens  seen  by  me. 

7.    Dendropanax  pendulum  (Sw.)  Dene.  &  Planch. 

A  shrub  about  4  m.  high.  Leaves  chartaceous  in  texture, 
ovate,  acute  or  bluntish  at  the  apex,  rounded  or  subcordate  at 
the  base,  triplinerved  and  rather  prominently  pinnately  veined,

the  blades  12  cm.  long  or  less,  nearly  twice  as  long  as  wide; 
petioles  rather  stout,  one  half  to  two  thirds  as  long  as  the  blades; 
peduncle  much  longer  than  the  leaves,  pendulous,  2  dm.  long  or 
less,  bracted  and  jointed  a  little  below  the  middle;  umbel  many- 
flowered;  pedicels  slender,  15-18  mm.  long;  flowering  calyx 
broadly  turbinate,  3.5  mm.  broad;  petals  oblong-lanceolate,  about 
as  long  as  the  calyx. 

Cockpit  Country,  Jamaica,  Harris  Q188,  from  Lapland,  near 
Catadupa;  this  specimen  agrees  with  the  type  specimen  of  Hedera 
nutans  Sw.,  in  the  herbarium  of  the  British  Museum  of  Natural 
History.  The  species  is  also  recorded  by  Marchand  from  Catha- 
rine's Peak,  collected  by  Eggers,  3651,  which  I  have  not  seen. 

8.  Dendropanax  grandiflorum  sp.  now 

A  tree,  about  8  m.  high.  Leaves  chartaceous,  obovate,  5-10 
cm.  long,  5  cm.  wide  or  less,  bluntly  pointed  at  the  apex,  cuneate- 
narrowed  at  the  base,  rather  strongly  pinnately  veined,  the  margins 
slightly  revolute,  the  stout  petioles  about  I  cm.  long  or  less; 
inflorescence  of  simple,  terminal,  few-flowered  umbels,  or  rarely 
a  secondary  umbel  borne  halfway  up  on  the  peduncle;  peduncle 
rather  stout,  3-5  cm.  long,  bracted  and  jointed  just  above  the 
base;  flowers  8  or  fewer  in  the  umbels;  pedicels  rather  stout, 
nearly  erect,  1.5-2  cm.  long;  flowering  calyx  8  mm.  high,  narrowly 
campanulate,  its  mouth  6-7  mm.  broad;  corolla  5  mm.  long  just 
before  expanding,  the  bud  rounded;  anthers  in  the  unopen  bud 
about  as  long  as  the  filaments;  fruit  oblong,  I  cm.  long,  7  mm. 
thick,  the  persistent  style  6-7  mm.  long. 

Peckham  woods,  Upper  Clarendon,  Jamaica,  July  7,  191 1, 
Harris  10QQ4. 

9.  Dendropanax  elongatum  sp.  nov. 

A  slender  tree  about  8  m.  high.  Leaves  clustered  at  the  ends

The  very  young  slate  of  the  inflorescence  does  not  enable  me 
to  give  a  description  of  the  flowers  of  this  interesting  tree,  and  its 
generic  position  is  therefore  uncertain.  Its  jointed  and  bracted 
peduncle  is  similar  to  that  of  Dendropanax  pendulum,  but  its 
foliage  is  altogether  different  from  that  species. 

10.  Dendropanax  grande  sp.  nov. 

A  tree  up  to  16  m.  high.  Leaves  clustered  at  the  ends  of  the 
branches,  ovate  to  ovate-elliptic,  coriaceous  in  texture,  rather 
prominently  pinnately  veined,  obtuse  at  both  ends,  the  blade  15 
cm.  long  or  less,  the  stout  petioles  as  long  as  the  blades,  or  shorter; 
peduncle  much  shorter  than  the  leaves,  erect,  stout,  about  4  cm. 
long,  bracted  at  the  base;  pedicels  numerous,  about  50,  rather 
stout,  2  cm.  long;  flowering  calyx  subhemispheric,  5  mm.  broad; 
petals  lanceolate,  about  as  long  as  the  calyx;  filaments  rather 
stout,  somewhat  longer  than  the  petals.

11.  Dendropanax  blakeanum  sp.  nov. 

A  slender  tree  about  8  m.  high.  Leaves  clustered  near  the 
ends  of  the  branches,  elliptic,  or  somewhat  obovate-elliptic,  rather 
coriaceous  in  texture,  faintly  pinnately  veined,  sharply  acute  at 
the  apex,  cuneate  at  the  base,  10  cm.  long  or  less;  the  petiole 
one  fifth  to  one  third  as  long  as  the  blade;  peduncle  erect,  as 
long  as  the  leaves  or  twice  as  long,  bracted  at  the  base;  umbels  8-16- 
flowered;  pedicels  slender,  2  cm.  long  in  fruit;  flower  buds  ovoid- 
hemispheric,  obtuse,  3  mm.  long  just  before  the  petals  unfold; 
calyx  in  young  fruit  turbinate,  4  mm.  broad;  fruit  subglobose,  5 
mm.  in  diameter;  the  conic  persistent  style  2.5  mm.  long.

17.    THE  GENUS  CAMERARIA  (PLUMIER)  L. 

The  genus  was  accepted  by  Linnaeus  from  Plumier,  C.  latifolia 
being  the  type  species,  and  C.  angustifolia  L.  also  appearing  in  the 
original  publication  of  the  genus,  which  is  wholly  West  Indian  in 
distribution,  so  far  as  I  am  aware. 

1.  Cameraria  latifolia  L.  Sp.  PI.  210.  1753 
This  is  a  shrub  or  tree  up  to  15  m.  high,  as  observed  by  me  at 
the  United  States  Naval  Station,  Guantanamo  Bay,  Cuba.  It  has 
characteristic  ovate-elliptic  acuminate  leaves.  Its  fruit  is  about 
6  cm.  long.  The  species  seems  to  be  widely  distributed  in  Cuba; 
occurring  in  the  provinces  of  Oriente,  Matanzas,  and  Havana. 
In  Jamaica  it  is  apparently  rare,  the  only  specimen  seen  by  me 
being  one  collected  by  Dr.  A.  Hollick  and  myself  {2045)  in  rocky 
woods  at  Negril,  the  extreme  western  end  of  that  island.  It  is 
recorded  from  Haiti  but  I  have  seen  no  specimens  from  Hispaniola, 
which  is  presumably  the  type  locality. 

2.  Cameraria  angustifolia  L.  Sp.  PI.  210.  1753 
My  knowledge  of  this  species  rests  wholly  on  Plumier's  descrip- 
tion and  plate  72,  figure  2,  where  it  is  illustrated  as  having  linear- 
acuminate  leaves  and  fruit  2.5  cm.  long.  According  to  Miller, 
cited  by  Grisebach,  Fl.  Br.  W.  I.  410,  it  was  found  in  Jamaica, 
but  it  is  unknown  to  us  from  that,  island. 

3.  Cameraria  retusa  Griseb.  Fl.  Br.  W.  I.  410.     1861 

(C.  angustifolia  Griseb.  loc.  cit.  not  L.) 
This  is  wholly  a  Cuban  species,  so  far  as  it  is  represented  in 
our  collections,  occurring  in  the  provinces  of  Santa  Clara,  Havana, 


6  Bkitton  :  Studies  of  West  Indian  plants 

Pinar  del  Rio,  and  on  the  Isle  of  Pines.  It  has  lanceolate  to 
oblong  leaves,  which  are  obtuse  and  emarginate  at  the  apex.  Its 
fruit  is  about  2  cm.  long,  the  narrowly  linear  terminal  wing  about 
as  long  as  the  ovoid  body.  Its  flowers  are  only  about  I  cm.  long, 
the  corolla  limb  about  1.5  cm.  wide. 

I  take  as  the  type  of  this  species  the  specimen  from  "West 
Indies,"  collected  by  Lane,  and  preserved  in  the  Kew  Herbarium. 

4.  Cameraria  oblongifolia  sp.  nov. 

A  tree  4-6  m.  high  with  slender  twigs.  Leaves  oblong  to 
oblong-lanceolate,  acutish  to  obtuse  or  minutely  emarginate  at 
the  apex,  narrowed  at  the  base,  2-3.5  cm-  long,  14  mm.  wide  or 
less,  the  slender  petiole  about  2  mm.  long;  corolla  about  17  mm. 
broad;  fruit  compressed,  lanceolate,  2-3  cm.  long,  about  I  cm. 
wide,  grooved  at  the  base  on  one  side,  the  terminal  wing  oblong- 
triangular,  obtuse,  about  as  long  as  the  body.

Shafer  2877;  also  represented  by  part  of  Wright's  Cuban  no. 
2Q50,  collected  at  Hanabana. 

The  other  part  of  Wright's  2950,  which  has  ovate-lanceolate 
acuminate  leaves,  may  represent  another  species.  It  has  much 
more  slender  and  longer  petioles  than  C.  oblongifolia,  but  the  speci- 
mens examined  by  me  are  too  imperfect  to  afford  a  complete 
description.  Combs'  no.  ig,  collected  in  Cieneguita  in  the 
province  of  Santa  Clara,  appears  to  be  the  same  as  this,  but  our 
specimen  of  that  number  also  is  incomplete. 

5.  Cameraria  microphylla  sp.  nov. 

A  tree  up  to  5  m.  high,  intricately  branched,  the  twigs  very 
slender.  Leaves  oblong  10  oblong-obovate,  I  cm.  long  or  less, 
2-4  mm.  wide,  emarginate  at  the  apex,  narrowed  at  the  base,  the 
margins  strongly  revolute;  fruit  2  cm.  long,  4-6  mm.  wide,  com- 
pressed, the  wing  oblique,  sinuate,  terminal  and  lateral,  similar 
to  that  of  C.  Jatifolia  but  very  much  smaller.

20.  NOTES  ON  SPECIES  OF  SOLANUM 

Solanum  Blodgettii  Chapm. 

This  species  is  cited  by  Mr.  O.  E.  Schulz*  as  a  synonym  of 
Solanum  bahamense  subarmatum  (Willd.)  O.  E.  Schulz,  but  he  has 
wholly  misunderstood  its  type  specimens,  which  show  that  it 
is  more  nearly  related  to  S.  verbascifolium  than  to  S.  bahamense; 
it  grows  plentifully  on  Key  West,  Florida  (Blodgett,  type;  Merrill; 
Pollard,  Collins  &  Morris  3;  Britton  320;  Lansing  1969s),  in  the 
Florida  Everglades  (Britton  237;  Small  &  Wilson  1678,  1962; 
Small  &  Carter  2674,  2673,  2936,  3101),  and  is  to  be  added  to  the 
West  Indian  Flora,  as  it  occurs  on  Cat  Cay,  Bahamas  (Millspaugh 
2341;  Brace  3749). 

The  varietal  name  Solanum  bahamense  subarmatum,  under  which 
Mr.  Schulz  groups  nearly  or  quite  unarmed  specimens  of  S. 
bahamense,  is  redundant,  for  there  is  every  transition  from  very 
prickly  plants  to  entirely  unarmed  ones  throughout  the  range 
of  the  species,  individual  bushes  often  bearing  prickles  below 
and  being  quite  devoid  of  them  above.  Harris  8169,  from 
Plowden  Hill,  Jamaica,  as  represented  by  our  specimen,  is  un- 
armed, though  the  duplicate  of  it,  examined  by  Mr.  Schulz,  is 
referred  by  him  to  the  typical  prickly  form. 

Solanum  boldoense  A.  DC. 

This  interesting  Cuban  vine  is  apparently  of  quite  local 
distribution    at   widely   separated    stations;    about    Matanzas   it

12  Britton  :  Studies  of  West  Indian  plants 

grows  especially  in  the  famous  gorge  of  the  Yumury  or  Yumuri 
River  (Rugel  145).  Mr.  Schulz  (loc.  cit.  170)  erroneously  spells 
this  "Tomory,"  while  Mr.  A.  H.  Moore*  also  has  it  wrong  as 
"Sumuri."  This  gorge  is  one  of  the  scenic  attractions  of  the 
northern  coast  of  Cuba;  the  handwriting  of  Rugel's  labels  is 
somewhat  difficult  to  decipher.  In  Pinar  del  Rio  it  inhabits 
limestone  rocks  at  San  Diego  de  los  Banos  {Britton,  Earle  & 
Gager  6674);  C.  Wright's  specimen  381  was  collected  in  Oriente; 
the  locality  of  the  type  specimen  is  doubtfully  cited  as  Havana. 

21.  NOTES  ON  TWO  JAMAICA  PLANTS 

Ampelocissus  Alexandri  Urban,  Symb.  Ant.  6:  15.  1909 
To  the  description  may  be  added  "berry  depressed-globose, 
black,  shining,  1.5  cm.  in  diameter,  the  pulp  watery;  seeds  2  or  3, 
depressed-obovoid,  slightly  rugose,  rather  deeply  and  broadly 
grooved,    5    mm.    long,    4    mm.    wide." 

Wooded  hillside,  Union  Hill  near  Moneague,  St.  Ann's, 
Jamaica,  at  500  meters  altitude,  Britton  &  Rollick  2767;  this 
station  is  within  a  few  miles  of  the  type  locality  at  Mount  Diablo.

An  examination  of  the  type  specimen  of  Swartz'  species  in 
the  herbarium  of  the  British  Museum  of  Natural  History  estab- 
lishes the  identity  of  these  species. 

22.  THE  GENUS  GINORIA  IN  CUBA 

GlNORIA   AMERICANA   Jacq. 

As  intimated  by  Koehne  (Bot.  Jahrb.  3:  349)  this  species 
may  sometimes  bear  spines,  as  observed  by  me  on  plants  in  the 
palm  barren  at  Santa  Clara,  in  March,  1910  (Britton  &  Wilson 
60Q3).  This  shrub  grows  along  brooks  and  streams,  attaining  a 
height  of  2.5  meters,  at  lower  elevations  in  all  provinces  of  Cuba, 
ascending  to  160  meters  in  Oriente.

Ginoria    spinosa    Griseb.    Cat.    PI.    Cub.    106.     1866 

I  know  this  only  from  Wright's  2545,  collected  in  eastern 
Cuba  (not  western  Cuba,  as  cited  by  Koehne).  Rugel's  727  from 
the  Rio  San  Juan  at  Matanzas,  as  shown  by  our  specimen,  is 
certainly  G.  americana  Jacq.  and  was  so  written  up  by  Grisebach, 
though  this  number,  as  studied  by  Koehne,  is  by  him  referred  to  G. 
spinosa.  The  true  G.  spinosa  Griseb.  {Wright  2545)  is  quite  a 
different  plant,  with  much  smaller  leaves  and  acicular  spines;  it 
is  possible,  however,  that  the  species  are  not  distinct. 

Ginoria    glabra    Griseb.    Cat.    PI.    Cub.    106.     1866 

Known  to  me  from  Wright's  2544,  collected  in  eastern  Cuba; 
and  from  Shafer's  8784,  collected  at  Farallon  de  la  Perla,  Oriente, 
where  it  grows  on  cliffs  as  a  shrub  6  dm.  high.  It  is  evidently 
quite  distinct  from  the  other  species. 

Ginoria  arborea  sp.  nov. 

A  tree,  8  meters  high,  the  trunk  up  to  2.5  dm.  thick,  the 
bark  gray,  the  branching  irregular,  the  twigs  of  the  season  4- 
angled  with  internodes  5-15  mm.  apart;  nodal  spines  4,  spread- 
ing, recurved,  yellowish,  I— 1.5  mm.  long.  Leaves  sessile,  linear- 
oblong,  1.5-3  cm-  l°ng>  2~5  mm-  wide,  coriaceous,  bright  green, 
shining,  obtuse  at  the  apex,  narrowed  at  the  base,  strongly  pin- 
nately  veined,  the  veins  prominent  on  both  surfaces;  flowers 
solitary  in  the  axils;  pedicels  filiform,  a  little  shorter  than  the 
leaves;  sepals  triangular-lanceolate,  acute,  4  mm.  long.

namo  Bay,  Cuba,  March  1909,  Britton  2217. 

Ginoria  curvispina  Koehne,  loc.  cit.  349.     1882 
In  the  palm  barren  near  Santayana,  Camagiiey,  this  species 
is  a  shrub  I  meter   high    {Britton  2368) ;   near  Tiffin,  Camagiiey, 
it  grows  in  wet  woods  and  becomes  nearly  3  meters  high.

Ginoria  Diplusodon  Koehne,  Bot.  Jahrb.  3:  350.     1882. 

This  beautiful  shrub  or  tree  inhabits  cliffs  and  rocky  hillsides; 
in  the  province  of  Santa  Clara  it  ascends  to  560  meters  on  the

southern  slope  of  the  Trinidad  Mountains,  and  at  sea  level  on 
the  southern  coast  becomes  a  tree  up  to  7  meters  high;  the  flowers 
are  rose  pink  to  purple  and  densely  cover  leafless  branches  in 
March.

I.     COMOCLADIA    PINNATIFOLIA    L.    Syst.    ed.     10,    86l.       1 759 

Professor  Urban  has  pointed  out.  to  me  that  Linnaeus,  who 
printed  the  speeific  name  pinnatif.,  more  likely  intended  this  con- 
traction to  mean  pinnatif olia  than  pinnatifida,  as  I  printed  it, 
following  the  Kew  Index. 

12.     COMOCLADIA    PLATYPHYLLA    A.    Rich. 

The  species  ranges  westward  in  Cuba  into  the  province  of  Pinar

Not  C.  acuminata  Moc.  &  Sesse;  DC.  Prodr.  2:  65.     1825. 

Known  hitherto  only  from  the  type  specimen,  this  species  has 
recently  been  collected  by  Rose,  Fitch  and  Russell  {4185)  at  San 
Pedro  de  Macoris,  Santo  Domingo.  The  broadly  cuneate  leaf- 
bases  distinguish  it  from  its  relatives. 

15.   Comocladia  glabra  Spreng. 

In  Flora  Portoricensis,  Professor  Urban  refers  to  this  species, 
the  C.  acuminata  Moc.  &  Sesse,  as  a  variety,  and  states  that  it  is 
Porto  Rican,  rather  than  Mexican  as  supposed  by  DeCandolle.

long,  2-bracted  at  the  top;  bracts  oblong,  obtuse,  about  1  cm. 
long;  fruiting  pedicels  stout,  subterete,  1-2.5  cm.  long;  sepals 
narrowly  oblong,  obtuse,  1.5  cm.  long,  entire;  capsule  about  as 
long  as  the  sepals,  tapering  into  a  stout-subulate  beak  about  6 
mm.  long. 

Mountains  of  northern  Oriente,  Cuba.  Type,  Shafer  8 121, 
from  Camp  La  Gloria,  south  of  Sierra  Moa,  December  1910.  The 
genus  is  hitherto  known  only  from  South  America.  The  Cuban 
species  most  resembles  Bonnetia  anceps  Mart.,  of  Brazil.  The 
generic  name  Kieseria  Nees,  has  priority  over  Bonnetia  Mart., 
which  is  a  homonym  of  Bonnetia  Schreb. 

33.     A   HYBRID   PALM 

On  the  sterile  "savannas"  north  and  east  of  Camaguey,  Cuba, 
palms  of  two  species  of  Copernicia  abound.  The  one,  C.  Jwspita, 
has  grey-green,  thin  foliage  with  spiny- toothed  petioles  about  as 
long  as  the  blades,  and  elongated,  slender  panicles;  the  other,  C. 
macroglossa,  has  bright  green,  rigid  foliage  with  very  short,  broad, 
unarmed  petioles,  the  blades  spiny-toothed  on  the  margins  of  the 
outermost  segments  and  on  the  upper  surface  of  the  ribs  of  the 
undivided  part,  the  stout  panicles  not  much  longer  than  the 
leaves  and  the  inflorescence  with  large  bracts. 

Of  the  two,  C.  hospita  is  the  more  abundant,  C.  macroglossa 
growing  in  colonies,  more  or  less  surrounded  by  it.  At  many 
places  where  the  two  grow  together,  plants  intermediate  in  foliage 
characters  occur,  their  leaves  with  spiny-toothed  petioles  of  various 
lengths,  the  blades  with  sparingly  spiny-toothed  margins,  other- 
wise smooth,  and  in  color  varying  from  green  to  grey,  the  panicles 
short  and  the  inflorescence  lacking  the  characteristic  large  bracts 
of  C.  macroglossa. 

Field  observations  during  four  days  with  Mr.  John  F.  Cowell, 
led  us  to  the  conclusion  that  these  intermediate  plants  are  of 
hybrid  origin  rather  than  a  third  species,  as  was  first  suggested.

On  rocks,  especially  along  rivers  and  brooks,  at  lower  and  middle 
elevations,  provinces  of  Oriente,  Matanzas,  and  Pinar  del  Rio, 
Cuba, 

The  use  of  the  name  P.  daphnoides  for  this  species  is  taken  from 
Graham's  description,  which  does  not  agree  with  our  specimens  in 
all  respects.  I  have  not  seen  the  type  specimen.  The  shrub  is 
abundant  in  the  limestone  hills  of  Pinar  del  Rio. 

12.     Portlandia  domingensis  sp.  nov. 

Foliage  similar  to  that  of  the  preceding  species,  but  the  petioles 
shorter,  about  2  mm.  long;  flowers  unknown;  capsules  short- 
peduncled,  oblong,  5-angled,  apparently  somewhat  fleshy,  4-4.5

36.    ADDITIONAL  SPECIES  OF  TABEBUIA  Gomez 

The  type  species  is  Bignonia  Tabebuya  Veil.,  of  Brazil,  a 
species  with  simple  leaves.  It  is  not  possible  to  separate  the 
group  into  two  genera,  the  one  with  simple,  the  other  with  com- 
pound leaves,  as  has  been  proposed  by  several  authors,*  calling 
the  compound-leaved  species  Tecomas,  and  the  true  type  of 
Tecoma  Juss.  is  Bignonia  stans  L.  {Tecoma  stans  HBK.,  Steno- 
lobinm  stans  Seem.).  The  two-lipped  calyx  of  the  type  species  of 
Tabebuia  is  not  constant  through  the  group. 

Tabebuia  Brooksiana  sp.  nov. 

A  tree,  up  to  30  m.  high.  Leaves  4-7-foliolate;  petioles  12  cm. 
long  or  less;  petioles  slender,  1-4  cm.  long;  leaflets  oblong,  oblong- 
lanceolate  or  oblong-oblanceolate,  chartaceous,  5-12  cm.  long,  4 
cm.  wide  or  less,  faintly  shining  above  with  the  veins  impressed, 
dull,  mostly  finely  reticulate-veined  when  mature,  and  lepidote 
beneath,  with  the  midvein  and  lateral  veins  prominent,  obtuse, 
acute  or  retuse  at  the  apex,  the  base  obtuse  or  acutish;  flowers 
clustered;  calyx  2-lipped,  10-15  mm-  long;  corolla  pink,  5-6  cm. 
long,  the  tube  about  5  mm.  long,  the  narrowly  campanulate 
throat  about  3.5  cm.  long,  the  limb  about  1.5  cm.  long,  its  un- 
dulate lobes  ciliolate. 

Woodlands,  provinces  of  Oriente  and  Camaguey,  Cuba,  from 
sea-level  up  to  350  m.  altitude.  Type  from  Ensenada  de  Mora, 
Oriente  {Britton,  Cowell  &  Shafer  12985).  Referred  by  Grisebach 
to  Tecoma  Leacoxylon  Mart,  and  to  T.  Leucoxylon  reticularis 
Griseb.  The  species  is  named  in  honor  of  Mr.  Theodore  Brooks 
of  Guantanamo,  who  has  rendered  important  aid  to  scientific 
exploration.  Tecoma  heptaphylla  A.  Rich,  in  Sagra,  Hist.  Cub. 
11:  106  (not  Martius),  described  as  with  7-foliolate  leaves  from 
Vuelta  de  Abajo  (Pinar  del  Rio),  Cuba,  is  not  known  to  me;  I 
have  seen  no  species  with  7-foliolate  leaves  from  western  Cuba. 

Tabebuia  Shaferi  sp.  nov. 

A  tree,  up  to  10  m.  high.  Larger  leaves  6-8-foliolate ;  petioles 
3-4  cm.  long;  petiolules  2  cm.  long  or  less;  leaflets  ovate-oblong  to 
suborbicular,  chartaceous,  the  larger  6  cm.  long,  3-5  cm.  wide, 
dark  green  above,  paler  beneath,  minutely  and  densely  reticulated

foliolis  latioribus. 

Tabebuia  pachyphylla  sp.  now 

A  tree,  up  to  12  m.  high.  Petioles  stout,  6-8  cm.  long;  petiololes

coriaceous,  5-12  cm.  long,  2.5-6  cm.  wide,  lustrous  above,  dull 
and  densely  minutely  reticulate-veined  beneath,  the  midvein 
prominent,  the  lateral  veins  slender,  the  apex  bluntly  acute,  the 
base  rounded  or  subcordate;  flowers  pink,  clustered;  calyx  15  mm. 
long,  bluntly  lobed;  corolla  pink,  glabrous,  about  5  cm.  long,  its 
narrow  throat  about  twice  as  long  as  the  limb,  its  lobes  rounded. 

Mountains  of  northeastern  Cuba.  Type  specimen  collected 
at  Arroyo  del  Medio,  Sierra  Nipe,  Oriente,  Cuba,  450-550  m. 
alt.  (Shafer  364s). 

Tabebuia  trinitensis  sp.  nov. 

A  tree  up  to  10  m.  high.  Leaves  4-foliolate  or  5-foliolate; 
petioles  slender,  8-1 1  cm.  long;  petiolules  slender,  4  cm.  long  or  less; 
leaflets  thin-chartaceous,  oblong  or  oblong-lanceolate,  dark  green 
above,  paler  and  lepidote  beneath,  the  larger  ones  11-15  cm.  long, 
3-4  cm.  wide,  bluntly  acute  or  acuminate  at  the  apex,  obtuse  at 
the  base,  finely  reticulate-veined  and  the  primary  venation  rather 
prominent  on  both  sides. 

Hanabanilla  Falls,  Trinidad  Mountains,  province  of  Santa 
Clara,  Cuba  (Britton,  Earle  &■  Wilson  4866). 

The  description  is  from  leaf-specimens  only  but  these  indicate 
that  the  tree  is  a  species  distinct  from  all  others  of  Cuba.  The 
ultimate  venation  and  texture  of  the  leaflets  differentiate  it  from 
T.  Brooksiana  Britton. 

Tabebuia  calcicola  sp.  nov. 

A  slender  tree,  up  to  6  m.  high.  Leaves  2-5-foliolate;  petioles 
stout,  lepidote,  4-5  cm.  long;  petiolules  lepidote,  1.5  cm.  long  or 
less;  leaflets  coriaceous,  light  green,  ovate  to  ovate-oblong,  3.5-8

FURTHER   STUDIES   OF   BADIERA   DC. 

Since  the  publication  of  my  former  paper  on  this  genus  (Bull. 
Torrey  Club  37:  360-363.  1910),  additional  specimens  which 
have  come  to  hand  afford  the  following  notes  and  descriptions. 

1.   Badiera  Penaea  (L.)  DC. 

Professor  Urban  has  informed  me  that  my  opinion  that  this 
is  identical  with  Badiera  domingensis  (Jacq.)  DC.  is  correct, 
although  he  has  distributed  Santo  Domingo  specimens  under  the 
name  B.  domingensis. 

la.   Badiera  portoricensis  sp.  nov. 

A  tree  up  to  6  m.  high,  the  trunk  sometimes  1.5  m.  in  diameter, 
the  slender  branches  ascending,  the  young  twigs  appressed- 
pubescent.  Leaves  subcoriaceous,  obovate,  3  cm.  long  or  less, 
7-15  mm.  wide,  bright  green  and  shining  above,  paler  and  rather 
dull  green  beneath,  both  surfaces  with  short,  scattered  hairs  when 
young,  becoming  glabrate  above,  the  midvein  slightly  impressed 
above,  rather  prominent  beneath,  the  lateral  veins  few,  distant, 
obscure,  the  apex  rounded  or  obtuse,  the  base  narrowed  or  cuneate, 
the  pubescent  petioles  1-2.5  mm.  long;  inflorescence  few-several- 
flowered,  4-6  mm.  long;  bracts  ovate  or  ovate-lanceolate,  acute, 
pubescent,  0.5  mm.  long;  pedicels  appressed-pubescent,  1.5-2.5 
mm.  long;  sepals  broadly  ovate,  obtuse,  ciliolate,  the  larger  about 
1  mm.  long;  petals  white;  keel  appressed-pubescent,  2  mm.  long, 
narrowed  below;  fruit  about  6  mm.  wide,  about  5  mm.  high, 
finely  pubescent,  narrowly  margined,  notched  at  the  apex,  sub- 
truncate  at  the  base,  its  stipe  about  0.6  mm.  long. 

Rocky  slopes  and  hillsides,  western  Porto  Rico,  especially 
on  serpentine,  from  sea-level  to  700  m.  altitude.  Type  collected 
at  Guanajibo,  near  Mayaguez  (Britton,  Cornell  &  Brown  4349). 
Recorded  by  Bello  from  my  type  locality  as  B.  domingensis  DC. 
[Polygala  domingensis  Jacq.;  B.  Penaea  (L.)  DC]  of  Hispaniola, 
to  which  species  it  is  nearest  related,  but  which  differs  in  pilose- 
pubescent  twigs,  rather  densely  pubescent  leaves,  and  much  more 
pubescent,  shorter-pedicelled  flowers.

2.    Badiera  virgata  Britton 
The  specimen  referred  to  by  me  under  B.  oblongata  Britton 
{Britton  &  Wilson  6066)  from  Santa  Clara,  Cuba,  is  now,  in  the 
light  of  additional  material,  put  with  B.  virgata,  as  a  broad-leaved 
race. 

4.   Badiera  diversifolia  (L.)  DC. 

This,  the  only  Jamaican  species  of  the  genus,  forms  a  tree 
up  to  6  m.  high,  as  at  St.  Ann's  Bay  {Britton  24Q8). 

5.  Badiera  cubensis  Britton 

In  the  original  description  of  this  species  (Bull.  Torrey  Club 
37:  362),  I  included  too  many  citations  of  specimens.  C. 
Wright's  Cuban  1913  consists,  apparently,  of  three  species;  it  is 
to  the  specimen  with  abruptly  acuminate  leaves  cuneate-narrowed 
at  the  base,  4-6  cm.  long,  that  the  name  should  be  restricted.  As 
shown  by  specimens  from  Bahia  Honda,  Pinar  del  Rio  (P.  Wilson 
9429)  the  leaves  vary  to  obovate.  The  fruit  is  glabrous  when 
mature,  its  slender  stipe  2  mm.  long. 

5a.    Badiera  Fuertesii  Urban,  Symb.  Ant.  7:  244.     1912 

A  tree  of  the  mountains  of  Santo  Domingo,  with  glabrous 
leaves,  strongly  reticulate-veined  on  the  upper  surface. 

6.  Badiera  Montana  Britton 

Described  from  fruiting  specimens  collected  in  the  Trinidad 
Mountains,  Santa  Clara,  Cuba.  Flowering  specimens  with  ap- 
parently the  same  foliage  and  pubescence  come  from  limestone 
hills  in  the  vicinity  of  Sumidero,  Pinar  del  Rio  {Shafer  13819),  but 
flowers  from  the  Trinidad  Mountain  tree  are  needed  to  make  the 
identity  wholly  satisfactory. 

8.   Badiera  propinqua  sp.  nov. 

Twigs  slender,  densely  appressed-pubescent.  Leaves  ovate  to 
ovate-elliptic,  2-4.5  cm-  l°ng.  8-25  mm.  wide,  bluntly  acute  or 
obtuse  and  emarginate  at  the  apex,  narrowed  or  obtuse  at  the 
base,  sparingly  short-pubescent  on  both  sides  or  becoming  glab- 
rous, the  midvein  impressed  above,  prominent  beneath,  the  slender 
lateral  veins  6  to  8  on  each  side  of  the  midvein,  the  appressed- 
pubescent   petioles    1.5-3   mm.   long;  inflorescence   few-flowered,

4-5  mm.  long;  bracts  ovate,  densely  pubescent,  scarcely  0.5  mm. 
long;  pedicels  slender,  apprcssed-pubescent,  1.5-2.5  mm.  long; 
sepals  suborbicular,  rounded,  pubescent,  the  larger  about  1.3  mm. 
long;  petals  white;  keel  pubescent  on  the  sides,  about  2.5  mm. 
long;  fruit  (from  Wright  1913,  in  part)  10  mm.  wide,  7  mm.  long, 
deeply  notched,  scarcely  margined,  glabrous,  decurrent  on  its 
stipe,  which  is  about  2  mm.  long. 

Cuba.  Type  collected  between  Los  Palacios  and  San  Juan 
de  Zayas,  Pinar  del  Rio  (Shafer  118 18).  The  description  is 
drawn  to  include  the  part  of  Wright  191 3,  and  Wright  3496,  pre- 
viously referred  by  me  to  B.  cubensis.  The  part  of  Wright  115, 
included  by  me  in  the  original  description  of  B.  cubensis,  is  perhaps 
referable  here  also. 

9.   Badiera  punctata  sp.  nov. 

A  shrub  about  1  m.  high,  with  slender,  ascending,  or  nearly 
erect  branches,  the  twigs  densely  appressed-pubescent  with  short 
hairs.  Leaves  ovate  to  ovate-elliptic,  firm  in  texture,  1.5-2.5  cm. 
long,  12  mm.  wide  or  less,  obtuse  or  emarginate  at  the  apex,  obtuse 
at  the  base,  the  midvein  impressed  above,  prominent  beneath, 
the  lateral  veins  3  or  4  on  each  side,  the  upper  surface  strongly 
punctate,  shining  and  glabrous  or  nearly  so,  the  under  surface 
dull,  the  petioles  about  1.5  mm.  long;  inflorescence  few-flowered; 
bracts  scarcely  0.5  mm.  long;  fruiting  pedicels  slender,  nearly 
glabrous,  2-2.5  mm.  long;  sepals  ovate,  obtuse,  ciliate,  about  1 
mm.  long;  fruit  (not  quite  mature)  "green  and  red,"  7  mm.  wide, 
about  as  long  as  wide,  shallowly  notched  at  the  apex,  obliquely 
subtruncate  at  the  base,  narrowly  margined,  slightly  pubescent, 
its  stipe  1-1.5  mm.  long. 

Near  a  stream,  Arroyo  del  Medio  above  the  falls,  Oriente,  Cuba 
(Shafer  3644).  The  leaves  droop  at  night,  a  phenomenon  also 
observed  in  B.  virgata. 

10.   Badiera  heterophylla  sp.  nov. 

An  upright  shrub  6  dm.  high,  the  twigs  short-pubescent  with 
somewhat  spreading  hairs.  Leaves  of  two  quite  different  forms, 
(1)  narrowly  ovate,  3-4  cm.  long,  12-18  mm.  wide,  bluntly  acute 
at  the  apex,  (2)  elliptic,  2-2.5  cm-  l°ng.  12-14  mm.  wide,  rounded 
or  obtuse  at  the  apex;  both  forms  emarginate  at  the  apex,  nar- 
rowed or  obtuse  at  the  base,  sparingly  short-pubescent  and  dull 
on  both  sides,  the  midvein  impressed  above,  prominent  beneath, 
the  slender  lateral  veins  only  2  or  3  on  each  side  of  the  midvein,

about  5  mm.  long;  bracts  about  0.5  mm.  long;  pedicels  pubescent, 
2  mm.  long  or  less;  sepals  rounded,  pubescent,  the  larger  about 
1  mm.  long;  "flowers  yellow";  petals  slightly  pubescent  in  the 
bud;  fruit  7-8  mm.  wide,  about  5  mm.  high,  margined,  rather 
deeply  notched,  sparingly  pubescent  when  young,  glabrous  when 
mature,  slightly  decurrent  on  its  stipe  which  is  about  1.5  mm.  long.

not.  Other  specimens  referable  to  P.  confusa  are:  Healthshire  Hills  near  Salt  Island

mouth  of  Santiago  Harbor  {Britton  &  Cowell  12632). 

9.    Plumiera  trinitensis  sp.  nov. 

A  tree  5  m.  high.  Leaves  oblong  to  oblong-oblanceolate,  11 
cm.  long  or  less,  1.5-3.5  cm-  wide,  obtuse  or  emarginate  at  the 
apex,  gradually  narrowed  to  the  base,  glabrous  above,  pubescent 
on  the  veins  beneath,  the  midvein  broad,  channeled  above, 
prominent  beneath,  the  lateral  veins  rather  widely  spreading, 
2-4  mm.  apart,  united  near  the  revolute  margins;  petioles  1.5-2.5 
cm.  long;  follicle  slightly  curved,  pointed,  18  cm.  long,  about 
1.5  cm.  thick. 

Dry  hillside,  La  Vigia,  Trinidad,  Santa  Clara  {Britton  &  Wilson 
5514).  Similar  to  P.  jamaicensis  Britton,  which  is  a  glabrous 
species  up  to  10  m.  high,  with  broader  leaves. 

{Harris  9996)  is  not  complete.     In  1895,  E.  Campbell  collected  a  Plumiera  at  Con- 
stant Spring  {5073),  which  may  be  P.  obtusa. 

Growing  with  P.  confusa  on  Great  Goat  Island  there  is  a  Plumiera  which  has 
leaves  over  3  dm.  long,  narrowly  oblong  to  linear-oblong,  some  of  them  not  more 
than  3  cm.  wide,  and  all  long-acuminate  at  the  apex  (Britton  1870).  It  was  not  in 
flower  at  the  time  of  my  visit,  March  4,  1908,  but  I  obtained  its  fruit,  which  is  much 
like  that  of  P.  confusa,  and  its  leaf-venation  resembles  that  of  P.  confusa  also;  it 
may  be  that  P.  confusa  is  sufficiently  heterophyllous  to  have  these  narrow,  elongated, 
long-pointed  leaves.

Guadaloupe;  I  studied  the  type  specimen  of  C.  polyadena  in  the 
Candollean  herbarium  at  Geneva  a  number  of  years  ago;  it  is, 
in  my  opinion,  specifically  distinct  from  the  Jamaica  plant.

C.  granulans.  It  would  therefore  appear  that  C.  nanus  was 
entered  as  Jamaican  by  Mr.  Clarke  in  error.  C.  granulans  on 
the  other  hand  is  now  known  to  me  to  inhabit  dry  soil  at  Long 
Acre  Point  near  Black  River  (Britton  1383). 

Cyperus  ignotus  sp.  nov. 

Perennial,  glabrous;  culm  rather  stout,  smooth,  bluntly  3- 
angled,  about  5  dm.  high.  Basal  leaves  as  long  as  the  culm  or 
longer,  smooth,  2.5-4  mm.  wide,  those  of  the  involucre  similar, 
much  longer  than  the  inflorescence,  sometimes  3  dm.  long;  umbel 
compound, its  primary  rays  8  cm.  long  or  less;  spikelets  compressed, 
capitate,  6-8-flowered,  the  heads  numerous,  8-10  mm.  in  diameter; 
rachis  wingless;  scales  ovate-lanceolate,  mucronulate,  very  faintly 
nerved,  closely  appressed  and  overlapping,  2  mm.  long;  style  3- 
cleft;  achene  oblong,  trigonous,  1.3  mm.  long,  about  twice  as  long

Eleocharis  microcarpa  Torr.  (E.  minima  Kunth),  was  re-

determination  of  the  specimen  from  the  interior  of  Manchester 
preserved  in  the  Kew  herbarium  was  subsequently  doubted  by

Owing  to  two  different  species  having  been  distributed  as 
Scirpus  juncoides  under  C.  Wright's  Cuban  No.  1533,  I  formerly 
misidentified  Professor  Underwood's  No.  3364  and  recorded  it* 
as  Stenophyllus  subaphyllus  (Clarke)  Britton,  a  species  apparently 
restricted  to  eastern  Cuba.

48.    THE   GENUS   HEPTANTHUS   Griseb. 

A  Cuban  genus,  of  which  three  species  were  described  at  the 
place  of  original  publication  (Cat.  PI.  Cub.  148.  1866);  all  were 
from  western  Cuba,  H.  cochlearifolius  Griseb.  being  typical,  and 
none  have  since  been  added  to  the  genus.  I  now  propose  three 
others,  all  from  eastern  Cuba. 

Leaf-blades  glabrous  above  or  merely  puberulent. 

Peduncles  longer  than  the  leaves.  1.  H.  cochlearifolius. 

Peduncles  shorter  than  the  leaves. 

Leaf-blades   orbicular-ovate,    1-2    cm.    long;    petioles 

densely  villous.  2.  H.  cordifolius. 

Leaf-blades  triangular-  ovate,  4-6  mm.  long;  petioles 

sparingly  villous.  3-  H.  Shaferi. 

Leaf-blades  pubescent  on  both  surfaces. 

Leaf-blades  repand-dentate;  peduncles  much  shorter  than 

the  petioles.  4-  H.  brevipes. 

Leaf  blades  incised-serrate  or  lobed;  peduncles  as  long  as 
the  leaves  or  longer. 
Leaf-blades  12  mm.  long  or  less,  incised-serrate.  5.  H.  ranunculoides. 

Leaf-blades  1-2.5  cm-  long,  deeply  3-lobed,  the  lobes 

coarsely  few-toothed.  6.  H.  lobaius. 

I.     Heptanthus  cochlearifolius  Griseb.   Cat.   PI.   Cub.    148. 

1866 

Type  locality:  Western  Cuba. 

Distribution:  Pine-lands  and  savannas,  Pinar  del  Rio. 

The  upper  leaf-surfaces  are  glabrous  or  nearly  so. 

A  plant  related  in  leaf-form,  but  with  the  upper  leaf-surfaces 
densely  puberulent  is  common  in  pine-lands  and  white  sand  in  the 
central  districts  of  the  Isle  of  Pines,  but  could  not  be  found  in 
flower  during  our  visit  to  this  region  in  February  and  March,  1916 
(Britton  &  Wilson  14163) ;  it  is  therefore  referred  to  this  species, 
with  doubt.

has  much  rougher  upper  leaf-surfaces  and  a  much  smoother  calyx 
than  S.  Sebestena  (often  glabrous),  and  its  yellow  or  orange  fruit 
is  shorter-beaked  than  the  white  fruit  of  that  species;  the  corolla  of 
S.  brachycalyx  has  a  narrower  limb  than  that  of  S.  Sebestena.  The

52.     CLEOME  PROCUMBENS  Jacq.  AND  ITS  RELATIVES 

The  small,  simple-leaved  Cleomes  of  the  West  Indies,  form  an 
interesting  and  peculiar  group  of  the  genus,  very  different  in 
habit  and  aspect  from  the  large,  typical,  compound-leaved  ones. 
Seven  species  appear  to  be  represented. 

Annuals  or  biennials. 
Pedicels  filiform. 

Leaves  linear-oblong;  pod  subterete.  1.  C.  Sloanei. 

Leaves  filiform;  pod  compressed.  2.  C.  guianensis. 

Pedicels  very  short;  leaves  very  narrowly  linear.  3.  C.  stenophylla. 

Perennials  with  woody  roots. 

Pod  acute  or  acuminate;  leaves  linear  to  oblong,  acute  or 
acuminate. 
Leaves  acuminate;  pedicels  half  as  long  as  the  pods.  4.  C.  procumbens. 

Leaves  acute;  pedicels  as  long  as  the  pods  or  longer. 

Petals  about  4  mm.  long;    leaves  oblong  to  oblong- 
lanceolate.  5.  C.  Wrightii. 
Petals  8-10  mm.  long;  leaves  narrowly  linear.  6.  C.macrorhiza. 
Pod  obtuse;  leaves  ovate  or  elliptic,  obtuse  or  rounded.  7.  C.  obticsa. 

I.    Cleome  Sloanei  Urban,  Symb.  Ant.  5:  347.     1907 

Grassy  and  sandy  places,  at  low  elevations,  southern  side  of 
Jamaica. 

This  species  is  referred  by  Fawcett  and  Rendle,  as  previously 
by  other  authors,  to  C.  procumbens  Jacq.,  which  is,  apparently, 
confined  to  Hispaniola.

ently also  erroneously  referred  to  Jamaica,  as  Jacquin's  figure  of 
the  type  would  seem  to  represent  a  well-marked  species,  not 
collected  since  its  original  discovery.

Linnaeus  included,  in  his  citations  of  synonyms  of  this  species, 
several  others,  but  his  description  of  it,  together  with  his  having 
received  a  Jamaica  specimen  from  the  collection  of  Patrick  Browne, 
prior  to  his  publication,  as  I  am  informed  by  Dr.  B.  Daydon 
Jackson,  Secretary  of  the  Linnaean  Society  of  London,  show  that 
the  name  is  to  be  restricted  to  the  Jamaica  plant.  Subsequent 
authors  have  confused  it  with  species  from  other  islands  and  from 
continental  tropical  America.  The  identity  of  Cassia  virgata  Sw. 
was  established  for  me  by  Mr.  William  Fawcett  at  the  British 
Museum  of  Natural  History.  Cassia  stricta  Schrank,  from  the 
illustration  and  the  Jamaica  habitat,  appears  referable  here,  but 
Schrank's  description  of  the  plant  is  not  altogether  conclusive; 
he  says  the  root  is  annual. 

18.  Chamaecrista  Dussii  sp.  nov. 

Perennial,  villous-pubescent,  erect,  simple,  5-9  dm.  high,  some- 
what woody.  Stipules  narrowly  lanceolate,  strongly  striate,  10- 
12  mm.  long;  leaves  5-7  cm.  long;  petiolar  gland  close  to  the 
lowest  leaflets,  scutelliform,  sessile,  slightly  concave,  nearly  1  mm. 
in  diameter;  leaflets  about  17  pairs,  linear,  pubescent  on  both 
sides,  10-18  mm.  long,  2-3  mm.  wide,  obtuse,  mucronate,  in- 
equilateral, the  mid  vein  excentric,  the  lateral  veins  few  and 
distant;  peduncles  4-6  mm.  long;  sepals  lanceolate,  acuminate, 
pubescent,  about  7  mm.  long;  petals  obovate,  8-10  mm.  long; 
pod  linear,  slightly  curved,  villous-pubescent,  obliquely  short- 
tipped,  3  cm.  long,  5  mm.  wide.

Type  locality  :  Guadeloupe. 

Distribution:  Guadaloupe;  Dominica;  Martinique;  Barba-

My  identification  of  this  species  is  based  on  my  examination  of 
the  type,  some  years  ago,  in  the  Candollean  herbarium  at  Geneva, 
Switzerland.  Notwithstanding  the  usually  sessile  petiolar  gland 
and  the  relatively  broader  leaflets,  I  am  not  confident  that  this 
species  is  distinct  from  the  preceding  one.

Distribution:  Jamaica;  province  of  Havana,  Cuba;  Grand 
Cayman;  Andros,  New  Providence  and  Eleuthera,  Bahamas; 
northern  South  America  and  recorded  from  Central  America. 

The  plant  of  the  Bahamas  was  referred  by  me  with  some  doubt 
(Bull.  N.  Y.  Bot.  Gard.  3:  443)  to  Cassia  aspera  Muhl.,  which  it 
closely  resembles,  except  in  the  petiolar  gland.  Cuban  and 
Jamaican  specimens  differ  from  the  Bahaman  in  having  the  "gland 
somewhat  longer-stalked. 

I  have  not  been  able  to  study  an  authentic  specimen  of  C. 
riparia.  Bentham's  record  of  it  as  West  Indian  was  based  upon 
a  plant  collected  in  Cuba  by  Liebmann,  preserved  in  the  Kew 
herbarium.

The  recognition  of  the  plant  of  Curacao  as  typical  Cassia

33.  Rondeletia  bicolor  sp.  nov. 

A  shrub  about  1.7  m.  high,  the  twigs  ascending,  slender, 
densely  short-pubescent  when  young.  Stipules  triangular-lanceo- 
late, rather  abruptly  attenuate  from  a  broad  base,  short-pubescent, 
about  3  mm.  long;  leaves  oblong  or  oblong-oblanceolate,  cori-

leaves  acute  at  both  ends,  bipartite,  persistent,  obtuse  stipules; 
corymbose  peduncled  flowers,  the  calyx  truncate,  with  five  short 
teeth.  The  genus  of  this  plant  was  questioned  by  A.  Richard 
(in  Sagra,  Hist.  Cub.  n  :  13),  and  I  do  not  know  any  species  which 
answers  to  the  description. 

Rondeletia  americana  L.  Sp.  PI.  172.     1753 

This,  the  type  of  the  genus,  is  also  recorded  by  De  Candolle 
as  found  at  Havana  by  Ossa,  and  Grisebach  (Fl.  Br.  W.  I.  327) 
mentions  it  as  Cuban.  I  know  the  plant  only  from  St.  Vincent 
and  Jamaica. 

Rondeletia  laevigata  Ait.  Hort.  Kew.  ed.  2,  1:  366.     18 10 

De  Candolle  mentions  this  also  as  found  at  Havana,  but  no 
species  answering  to  the  description  is  known  to  me  from  Cuba; 
Grisebach  (Fl.  Br.  W.  I.  328)  indicates  that  it  is  from  the  island 
of  Trinidad. 

Rondeletia  leptacantha  DC.  Prodr.  4:  410.     1830 

Collected  by  Ossa,  near  Havana,  according  to  De  Candolle. 
Described  as  a  plant  with  opposite  spines,  broadly  oval,  subacute 
leaves,  the  twigs  and  leaves  subpilose  when  young,  the  slender 
peduncle  as  long  as  the  leaves  or  longer,  three-  to  five-flowered  at  the 
apex.  No  species  of  Rondeletia  known  to  me  answers  the  description. 
Grisebach  (Cat.  PI.  Cub.  133)  refers  the  plant  to  Chomelia  fascicu- 
lata  Sw.  [Anisomeris  fasciculata  (Sw.)  Schum.],  but  this  disposal 
of  it  is  not  satisfactory. 

57.     THREE  ERIOCAULONS  FROM  THE  ISLE  OF  PINES 

Eriocaulon  arenicola  Britton  &  Small,  sp.  nov. 

Plants  4-26  cm.  tall,  the  scapes  solitary  or  usually  several 
together;  leaves  ascending  or  spreading,  1—8  cm.  long,  linear- 
attenuate,  convex  beneath,  slightly  concave  above,  glabrous; 
scapes  slender,  mostly  6-angled,  slightly  spirally  twisted,  each

vate,   the  outer  ones  about   1.5   mm.   long;    flowers  numerous, 


32  Britton:  Studies  of  West  Indian  plants 

crowded;  bracts  very  broadly  cuneate,  fully  1.5  mm.  long,  short- 
hairy  at  and  near  the  apex;  sepals  of  the  staminate  flowers 
concave,  cuneate  to  obovate,  about  1.5  mm.  long,  exceeding  the 
corolla,  pubescent  at  the  apex;  corolla-lobes  minute,  ovate  to 
oblong-ovate,  obtuse;  anthers  about  0.25  mm.  long;  sepals  of  the

White  sand,  vicinity  of  Los  Indios  {Britton  &  Wilson  1417Q). 

This  plant  is  related  to  Eriocaulon  sigmoideum  C.  Wright.  It 
differs  from  it  in  the  larger  size,  the  more  compact  heads,  the  more 
copiously  pale-pubescent  and  longer  bracts,  the  smaller  staminate 
flowers,  and  the  sepals  of  the  pistillate  flowers  which  are  wider 
below  the  middle,  instead  of  at  the  top. 

Eriocaulon  fusiforme  Britton  &  Small,  sp.  nov. 

Plants  3-6.5  cm.  tall,  the  scapes  tufted,  usually  densely  so; 
leaves  ascending  or  recurved,  subulate-lanceolate,  1-2.5  cm.  long, 
thinnish,  concave,  glabrous;  scapes  relatively  slender,  spirally 
twisted,  prominently  5-angled,  each  subtended  by  an  obliquely 
opened  sheath  which  is  shorter  than  the  longer  leaves;  heads 
dense,  fusiform,  becoming  7-8.5  mm.  long,  acute,  glabrous,  brown- 
ish; bracts  of  the  involucre  ovate  to  oblong,  obtuse,  chartaceous, 
2-3  mm.  long;  flowers  numerous;  bracts  rhombic-ovate  or  rhom- 
bic-cuneate,  mostly  2  mm.  long,  acute  or  short-acuminate,  scarious, 
glabrous,  or  obscurely  fine-pubescent;  sepals  of  the  staminate 
flowers  spatulate  to  oblong-spatulate,  about  1  mm.  long,  some- 
times laciniate  at  the  apex,  about  equalling  the  corolla  or  exceeding 
it;  corolla-lobes  ovate;  anthers  about  0.15  mm.  long;  sepals  of 
the  pistillate  flowers  about  1.5  mm.  long,  boat-shaped,  strongly 
keeled  and  crested  above  the  middle,  acuminate;  petals  linear- 
elliptic  to  linear-spatulate,  1.5-2  mm.  long;  capsule  suborbicular 
or  orbicular-ovoid,  about  0.5  mm.  wide:  seeds  narrowly  oval, 
about  0.5  mm.  long. 

Pinelands,  Siguanea  {Britton  Sf  Wilson  14Q51). 

This  differs  from  all  described  Cuban  species  of  Eriocaulon. 
Its  short  stiff  scapes  and  fusiform  glabrous  or  nearly  glabrous 
heads  are  particularly  diagnostic. 

Eriocaulon  ovoideum  Britton  &  Small,  sp.  nov. 

Plants  6-1 1  cm.  tall,  the  scapes  tufted,  usually  densely  so; 
leaves  erect  or  ascending,   narrowly  linear-lanceolate  to  linear- 


Britton:  Studies  of  West  Indian  plants  33 

attenuate,  1-3  cm.  long,  concave,  thinnish,  glabrous;  scapes 
stoutish,  spirally- twisted,  sharply  5-angled,  each  subtended  by  an 
obliquely  opened  sheath  which  is  as  long  as  the  leaves  or  shorter; 
heads  very  dense,  ovoid  or  globose-ovoid,  becoming  6-8  mm.  long, 
obtuse,  tan-colored;  bracts  of  the  involucre  ovate  to  oblong,  1.5-3 
mm.  long,  obtuse,  glabrous,  chartaceous;  flowers  numerous;  bracts 
subreniform,  mostly  wider  than  long,  broadly  rounded  at  the  apex, 
scarious,  minutely  pubescent;  sepals  of  the  staminate  flowers 
obovate  to  cuneate,  concave,  fully  1  mm.  long,  erose  at  the  apex, 
mostly  exceeding  the  corolla;  anthers  ovoid,  about  0.1  mm.  long; 
sepals  of  the  pistillate  flowers  boat-shaped,  fully  1  mm.  long, 
keel-winged  and  crested  on  the  back,  abruptly  pointed:  petals 
spatulate,  about  1.5  mm.  long,  often  erose  at  the  apex;  capsule 
reniform,  about  1  mm.  wide;  seeds  broadly  oval,  fully  0.5  mm. 
long. 

White  sand,  vicinity  of  Los  Indios  {Britton  &  Wilson  14226). 
Related  to  Eriocaulon  fusiforme,  differing  in  stouter  habit,  the 
short  and  broad  heads,  and  in  the  broad  and  rounded  bracts. 

58.     UNDESCRIBED   CUBAN   SPECIES 
Dupatya  montana  sp.  nov. 

Stem  simple,  elongate,  stout,  densely  leafy.  Leaves  broadly

the  bracts  membranaceous,  obovate-cuneate,  1.8-2  mm.  long, 
0.6-0.8  mm.  broad,  with  a  tuft  of  short  hairs  on  the  back  at  the 
apex;  staminate  flowers  dimerous;  sepals  spatulate-obovate, 
about  1.9  mm.  long,  concave,  ciliate  at  the  apex;  pistillate  flowers 
dimerous;  sepals  elliptic,  concave;  stigmas  2;  ovary  globose- 
ovate. 

Collected  on  compact  red  iron  ore  along  trail  from  Rio 
Yamaniguey  to  Camp  Toa,  Oriente,  at  400  m.  alt.  (/.  A. 
Shafer  4473,  type);  also  collected  along  trail  from  Camp  La 
Barga  to  Camp  San  Benito  {Shafer  4104)  and  at  Camp  La

mm.  broad. 

Related  to  I.  piscipula  (L.)  A.  S.  Hitchc,  but  differing  in  the 
much  smaller  and  more  coarsely  reticulate  leaflets,  and  smaller 
fruit. 

Thickets  not  far  from  Cojimar,  Province  of  Havana  (Brother 
Leon  &  Father  M.  Roca  6194,  type);  also  collected  on  a  hill

This  monotypic  genus  of  Compositae  was  rediscovered  on  the 
southern  slope  of  Cajalbana  in  the  province  of  Pinar  del  Rio, 
Cuba,  by  Brothers  Leon  and  Charles  on  April  6,  191 5.  The 
genus  has  hitherto  been  imperfectly  known,  as  it  was  represented 
in  this  country  only  by  a  fragment  at  the  Gray  Herbarium, 
collected  by  Charles  Wright  in  western  Cuba.  Lascaillea  is  a 
woody  vine  related  to  Porophyllum.  The  leaves  are  reduced  to 
small  scales,  the  plant  resembling  certain  species  of  Ephedra 
much  more  closely  than  it  does  any  Eguisetum.

oblong,  about  2  mm.  long,  obtuse,  nearly  white  with  a  greenish 
midvein;  achene  trigonous,  obovoid,  about  0.5  mm.  long,  truncate; 
tubercle  low,  nearly  flat,  apiculate;   bristles  none. 

Moist  hole  on  the  O'Meara  Savanna,  Trinidad  (Britton  2491). 

Eleocharis  oropuchensis  sp.  nov. 

Roots  fibrous,  finely  filiform;  culms  finely  filiform,  densely 
tufted,  weak,  5  cm.  long  or  less,  the  upper  sheath  membranous, 
oblique  at  the  summit.  Spikelets  terminating  culms,  and  sessile 
at  the  base  of  the  plant;  compressed,  2-3  mm.  long,  ovate,  about  6- 
flowered ;  their  scales  ovate-oblong,  pale  or  brown  with  pale  mar- 
gins and  keel,  subdistichous,  blunt,  1.5  mm.  long;  style  3-cleft; 
achene  trigonous,  smooth,  pale,  about  0.5  mm.  long,  about  as  long

puche  Lagoon  (Britton,  Hazen  and  Freeman  11 55,  March  29,  1920). 

I  am  indebted  to  Mr.  N.  E.  Brown  for  comparing  this  little 
plant  with  West  Indian  and  South  American  species  in  the  Kew 
Herbarium,  where  he  was  unable  to  match  it.  He  remarks  upon 
its  unusual  character  of  having  both  terminal  and  basal  spikelets, 
and  compares  it  with  Chaetocyperus  Jamesoni  Steud.  from  Guaya- 
quil, Ecuador  (Jameson  360),  pointing  out  important  differences, 
however. 

Rynchospora  aripoensis  sp.  nov.

R.  turquinensis  is  a  member  of  the  Adenotrichi,  differing  from 
R.  costaricanus  and  R.  adenotrichos  in  the  narrower  lanceolate 
long-acuminate,  instead  of  broadly  ovate,  abruptly  acuminate 
leaflets;  from  R.  Vera-Crucis  in  the  more  dense  pubescence  and 
the  texture  of  the  leaves.  It  is  more  closely  related  to  R. 
irasuensis  and  R.  miser.  In  habit,  leaf-form,  and  pubescence  it 
resembles  the  former,  but  the  inflorescence  is  mostly  simple,  the 
sepals  narrower,  and  the  drupelets  perfectly  glabrous;  neither 
have  any  5-foliolate  leaves  been  seen.  From  R.  miser  it  differs 
in  the  shorter  sepals  and  the  thicker  leaflets,  with  shorter  petioles, 
more  numerous  and  more  prominent  lateral  veins,  and  much 
closer  serrations.

Among  North  American  species  Poly  gala  rhynchosperma  is 
nearest  P.  paniculata  L.,  which  is  densely  stipitate-glandular 
and  has  shorter  wings  and  an  erostrate  seed.  The  Venezuelan 
P.  Funkii  Chod.,  known  to  me  only  from  Chodat's  description 
and  figures,  is  evidently  closely  related,  having  similar  bracts, 
seed,  and  stigma.  It  is. described  as  glabrous,  with  acute  lance- 
elliptic  sepals,  acute  wings,  and  a  crest  composed  on  each  side 
of  an  acute  triangular  entire  lamina  and  an  undivided  linear 
lobe.

Type  in  the  U.  S.  National  Herbarium,  No.  1,145,291,  col- 
lected on  banks  of  the  Yara  River,  Oriente,  August  14,  1922 
(E.  L.  Ekman   14852).

The  type  of  R.  calophylla  was  collected  in  the  Sierra  Maestra 
in  July,  1922,  by  Brother  Leon.  Dr.  Ekman  also  obtained  it  in 
August,  1922,  at  Arroyo  Corojo,  Nagua,  Oriente  (No.  14729). 


69.  AN    UNDESCRIBED  SPECIES  FROM   HISPANIC )LA 

Kallstroemia  incana  Rydberg,  sp.  now 

KaUstr.oemiu  cariba<         rban,  Symb.  Ant.  8:319.     1920.     Not 
K.  caribaea   Rydberg,   1910. 

A  diffusely  branched  herb,  somewli.it  woody  at  the  base; 
stems  spreading,  2-3  dm.  long,  with  coarser  spreading  and  finer 
more  appressecl  hairs,  terete;  stipules  linear-oblong,  2-3  mm. 
long,  tardily  deciduous;  leaves  I— 1.5  cm.  long;  petioles  2-3  mm. 
long;  leaflets  mostly  3  pairs,  obliquely  ovate,  3—5  mm.  long, 
hoary  on  both  sides,  acutish;  peduncles  2-3  mm.  long;  sepals 
lance-linear,  acute,  3  mm.  long;  petals  elliptic-obovate,  light 
yellow,  3  mm.  long;  fruit  grayish-strigose,  about  5  mm.  broad, 
the  beak  2  mm.  long,  conic  at  the  base;  carpels  cross-ridged  on 
the  back  and  reticulate  on  the  faces. 

Type  collected  at  Barahona,  Santo  Domingo,  July  1920, 
Fuertes  418  (herbarium  of  the  New  York  Botanical  Garden); 
also  collected  at  Rincon,  October  191 1,  Fuertes  1352. 

The  two  numbers  cited  were  determined  by  Urban  as  K. 
caribaea  and  included  under  that  name  in  his  Flora  Domingensis, 
but  it  differs  in  the  hoary  pubescence,  the  small  leaflets,  the  small 
petals,  scarcely  half  as  long  as  in  K.  caribaea,  the  short  peduncles 
and  short  beak  on  the  small  fruit.  It  approaches  more  K.  carta 
Rydberg,  from  ( "uracao.w  it  h  which  it  has  the  following  characters 
in  common:  small  leaflets,  short  peduncles,  small  petals  ami 
fruit,  and  short  beak;  but  it  is  more  canescenl,  more  branched, 
with  shorterinternodes  and  smaller  lea\  es.and  the  beak  different, 
not  at  all  swollen.

The  venation  of  the  leaf  of  this  species  is  on  the  same  plan 
as  that  of  A.  Guildingii  Schott,  but  in  outline  the  slight  constric- 
tion above  the  basal  lobes  brings  it  nearer  to  A.  panduraeforme 
Schott.

2-6  cm.   long,    15  30  mm.  broad,  ovate  or  oblong-lanceolate, 

acuminate,  rounded  at  the  base,  glabrous  on  both  sides  to  the  eye, 
but  with  a  microscopic  scattered  pubescence  above,  where  the 
midrib  is  also  minutely  puberulous;  primary  veins  3-  5  on  each 
side  of  the  midrib,  distant,  inarching  and  uniting  into  a  sub- 
marginal  vein  2  3  mm.  from  the  margin,  not  prominent  on  either 
surface.  Flowers  in  small  sessile  umbellate  clusters  at  the  nodes 
of  leafless  branches.  Bracts  very  minute.  Pedicels  2-2  V2  mm. 
long,  and  together  with  the  flowering  branches  minutely  puberu- 
lous. Calyx  5-lobed  to  the  base;  lobes  about  %  mm.  long,  ovate, 
obtuse,  think-  and  very  minutely  puberulous.  Corolla  about 
3  mm.  in  diameter;  tube  about  0.75  mm.  long.  glabrous;  lobes 
spreading,  about  1  mm.  long,  ovate,  subacute,  minutely  and 
densely  puberulous  within;  each  sinus  with  a  thickening  or  slight 
gibbosity,  which  seems  nearly  or  quite  to  touch  the  staminal 
column  so  as  to  form  5  small  pocket-like  entrances  to  the  tube  at 
the  base  of  the  lobes.  Staminal  column  subsessile,  about  0.75  mm. 
long,  somewhat  conical,  truncate  at  the  apex.  Corona  of  5 
lobes  arising  from  the  staminal  column  at  the  base  of  the  anthers, 
minute,  about  :4  mm.  long,  pressed  close  against  the  back  of 
the  anthers  and  shorter  than  the  latter,  ovate,  obtuse;  they  seem 
to  be  connected  at  the  base  by  a  minute  tooth  under  the  anther- 
wings,  but  in  the  dried  flowers  this  is  difficult   to  determine. 

Trinidad   (Dannouse  6419,  type).     Collected  in   1898. 

The  genus  Decastelma  is  very  like  Metastclma  in  appearance, 
but  differs  by  having  the  staminal  column  subsessile  instead  of 
with  a  long  stipe,  and  by  the  corona  arising  from  the  staminal 
column  at  the  base  of  the  anthers  instead  of  at  the  mouth  of  the 
corolla-tube.  But  the  description  of  the  corona  of  Decastelma 
as  given  by  Schlechter  is  entirely  wrong,  unless  the  flowers  on 
different  specimens  vary  very  much.  For  in  the  type  of  the 
genus,  D.  Broadwayi  Schltr.  (Broadway  474),  the  flowers  that  I 
have  examined  have  a  corona  consisting  of  5  lobes  only,  which 
are  shorter  than  the  staminal  column  and  pressed  close  to  it; 
they  are  broader  than  long  and  somewhat  truncate  at  the  three- 
toothed  top,  the  middle  tooth  being  minute. 

Probably  some  species  from  South  America,  now  placed  under 
the  genus  Metastelma,  really  belong  to  Decastelma.

74.  UNDESCRIBED  SPECIES  FROM  CUBA 

Andropogon  virginicus  graciliformis  Leon,  var.  nov. 

Lower  sheaths  not  equitant,  rather  terete,  glabrous;  culms 
slender  and  cylindrical  from  the  base,  usually  producing  one  or 
two  flowering  branches,  only  from  the  two  or  three  upper  nodes; 
nodes  of  the  inflorescence  long  pilose;  blades  at  first  narrowly  in- 
volute or  conduplicate  from  base  to  apex,  becoming  flat  and 
flexuous  in  age,  only  about  1.5  mm.  wide,  devoid  of  long  hairs 
towards  the  base;  spathes  becoming  reddish,  the  upper  ones  6 
to  9  cm.  long,  much  longer  than  the  racemes. 

Gravelly  soil,  Sabana  de  Motembo,  Santa  Clara,  Cuba  {Leon 
and  Loustalot  11343).  This  variety  may  be  readily  recognized 
by  its  basal  sheaths  not  strongly  compressed  and  equitant  as 
those  of  typical  Andropogon  virginicus  and  in  its  long  and  very 
slender  stems  and  narrow  leaves.  The  type  specimen  is  pre- 
served in  the  herbarium  of  Colegio  de  la  Salle,  Vedado,  Havana. 
We  are  indebted  to  Prof.  A.  S.  Hitchcock  and  Mrs.  Agnes  Chase 
for  suggestions  and  help.

on  the  border;  spikelets  in  pairs,  elliptic,  2.5  mm.  long,  1.2  to 
1.4  mm.  wide,  the  pedicels  scaberulous,  one  of  them  1  mm.  long, 
the  other  two-thirds  as  long;  glumes  covering  the  fruit,  thin, 
glabrous,  brownish-yellow;  second  glume  5-nerved,  short  pointed; 
sterile  lemma  faintly  3-nerved,  fruit  brown,  slightly  rugose, 
shining. 

Grassy  place,  Sabana  de  Motembo,  Santa  Clara,  Cuba  {Leon 
and  Loustalot  9354)-  Related  to  the  South  American  P.  hydro- 
phyllum  Henr.,  a  much  more  robust  plant,  and  to  the  Cuban 
P.  JVrightii;  this  is  taller  and  stiffer  than   P.   motembense,  from

1  mm.  long,  and  the  dark  colored  scaberulous  beak;  awns  un- 
equal, ascending,  the  central  one  slightly  recurved,  2  to  3  cm. 
long,  the  lateral  ones  somewhat  approximate,  one-half  as  long 
as  the  central  one  or  little  more. 

Arid  rocky  silicious  hillside,  Peladeros  de  Jauco,  southwest 
of  Baracoa,  Oriente,  Cuba  (Leon  12299). 

This  species  is  allied  to  A.  divaricata  Humb.  &  Bonpl.  of 
Mexico,  but  may  be  distinguished  by  its  much  longer  and  closely 
involute  leaves.  It  is  named  in  honor  of  Sr.  Enrique  Prada  of 
Jauco,  who  helped  very  efficiently  in  collecting  work.  The 
type  specimen  is  preserved  in  Colegio  de  la  Salle  Herbarium, 
Vedado,  Havana.

Colonel  Morales  Coello  of  the  Cuban  Navy,  in  recognition  of  his 
effective  help.  This  species  is  of  Chloris  Sagraeana  relationship, 
but  a  much  taller  plant;  it  also  differs  in  its  longer  and  broader 
leaves  and  more  leafy  stems.  The  type  specimen  is  preserved  in 
Colegio  de  la  Salle  Herbarium,  Vedado,  Havana.

1926]  BRITTON":    WEST    INDIAN    PLANTS  467 

I  have  placed  this  very  distinct  plant  under  Gravisia  because 
in  general  appearance  it  seems  more  nearly  allied  to  G.  aquilega 
Mez,  than  to  any  other  in  the  Kew  Herbarium.  But  the  flowers 
are  not  in  a  sufficiently  good  state  to  admit  of  complete  details 
being  given.  I  could  not,  however,  detect  any  ligules  upon  the 
petals,  nor  did  I  find  any  pollen  to  examine.  The  habit  of  its 
inflorescence  would  seem  to  distinguish  it  from  Aechmea.  [N.  E.

A  species  allied  to  Elsota  coriacea  (Bonpl.)  Blake  and  to 
E.  sylvestris  (Schlecht.)  Kuntze,  and  characterized  primarily  by 
the  numerous  thick  blunt  crests  of  the  fruiting  cell.  The  de- 
scription of  Securidaca  tenuijolia  Chod.,  of  Trinidad,  suggests 
this  species,  but  a  fruit  received  from  Berlin  of  Trinidad  Bot. 
Gard.  Herb.  no.  2703,  described  by  Chodat  as  a  velvety  form  of 
S.  tenuijolia,  proves  to  be  entirely  different  from  the  fruit  of 
E.  lophosoma.

Balandra  Bay,  Trinidad,  {IV.  G.  Freeman  njio). 

The  genus  Metastelma  is  one  that  urgently  requires  a  thor- 
ough revision,  for  as  understood  by  modern  authors  and  as  de- 
fined in  Bentham  &  Hooker,  Genera  Plantarum  2:  755,  it  com- 
prises three  very  distinct  types  of  coronal  structure,  which  in 
other  parts  of  the  order  are  held  to  constitute  generic  distinction, 
and  there  seems  no  valid  reason  why  these  differences  should  not 
be  considered  of  generic  value  in  this  case.  The  three  types  are: 
1,  Plants  with  the  coronal  lobes  inserted  at  the  sinuses  of  the 
corolla.  2,  Plants  with  the  coronal  lobes  inserted  at  the  base  of 
the  staminal  column.  3,  Plants  with  the  coronal  lobes  inserted 
at  the  top  of  the  staminal  column. 

Originally  the  genus  Metastelma  was  founded  by  Robert 
Brown  upon  a  plant  collected  in  the  Islands  of  St.  Croix  and  St. 
Christopher,  having  the  coronal  lobes  inserted  at  the  sinuses  of 
the  corolla  (type  1).  This  plant  (M.  parviflorum  R.  Br.)  1  find 
upon  comparison  with  the  type  to  be  identical  with  Thompson 
499,  collected  on  St.  Croix,  and  M.  Freemani,  above  described, 
has  the  same  type  of  structure  and  undoubtedly  is  a  true  species 
of  Metastelma.  But  modern  authors  seems  to  have  understood 
type  2  as  being  the  typical  structure  of  Metastelma.  While 
K.  Schumann  in  Engler,  Pflanzenfamilien  42:  229  has  placed 
plants  having  the  typical  structure  of  Metastelma  (i.  e.  type  1) 
under  the  genus  Irmischia,  founded  by  Schlechtendahl  in  Lin- 
naea  19:  738  upon  a  Mexican  plant  I  have  not  seen,  but  which 
from  description  may  prove  to  be  a  typical  Metastelma;  in  which 
case  Irmischia  will  rank  as  a  svnonvm  of  Metastelma.

As  to  types  2  and  3  mentioned  above,  I  consider  that  these 
should  be  separated  from  Melastelma  and  made  to  constitute 
separate  genera.      [N.  hi.   Brown\]

Type  in  the  herbarium  of  the  New  York  Botanical  Garden, 
collected  at  Maraval,  Trinidad,  in  1904  (I.  Dannouse  6946). 

Because  of  the  incompleteness  of  the  available  material,  there 
is  some  doubt  as  to  the  proper  reference  of  this  plant  to  Chimar- 
rhis, but  it  agrees  well  with  that  genus  in  the  characters  exhibited 
by  the  specimen  studied.
