INTRODUCTION 


This  part  was  compiled  in  accordance  with  the  Guide  for  contributors  to  the  Flora  of  southern 
Africa  (compiled  by  Leistner,  Ross  & De  Winter  and  available  from  the  Editor,  National  Botanical 
Institute,  Private  Bag  X 1 0 1 , Pretoria,  0001  South  Africa). 

The  maps  show  the  distribution  of  the  various  taxa  in  the  FSA  region  only. 

The  numbering  of  the  genera  is  according  to  De  Dalla  Torre  & Harms  in  their  Genera 
siphonogamarum  ( 1900-1907),  as  adapted  by  Arnold  & De  Wet  ( 1993,  Plants  of  southern  Africa: 
names  and  distribution). 


Background  to  this  Fascicle 

M.A.N.  Muller  completed  a revision  of  the  genera  Eriocephalus  L.  and  Lasiospermum  Lag.  for 
which  a Ph.D.  degree  was  conferred  upon  him  by  the  University  of  Stellenbosch  in  1988.  The 
results  of  his  thesis  had  not  been  published  by  the  time  he  tragically  died  in  a car  accident  in  April 
1997.  Permission  was  granted  by  the  University  to  publish  the  taxonomic  part  of  his  thesis  in  the 
FSA  format  as  it  was  considered  to  be  a valuable  contribution  to  plant  taxonomy  in  southern  Africa. 
P.P.J.  Herman  extracted  and  adapted  the  relevant  text  from  the  thesis  in  co-operation  with  H.H. 
Kolberg  and  translated  it  into  English.  However,  not  all  specimens  examined  by  Muller  were  seen 
by  Herman.  The  original  line  drawings  by  Blythe  Loutit  and  Elna  de  Bruyn  could  not  be  traced. 
The  figures  in  this  publication  were  scanned  from  a copy  of  the  thesis.

PREFACE 


The  genera  Eriocephalus  L.  and  Lasiospermum  Lag.  belong  to  the  tribe  Anthemideae  (Asteraceae), 
which  is  characterised  by  an  aromatic  scent  and  dissected  leaves;  the  pappus  is  often  absent  where- 
as paleae  are  often  present  (Muller  1988,  'n  Morfologiese  en  taksonomiese  studie  van  die  genusse 
Lasiospermum  Lag.  en  Eriocephalus  L.  ( Asteraceae ) in  snidelike  Afrika,  unpublished  Ph.D.  thesis; 
Bremer  1994,  Asteraceae.  cladistics  and  classification).  The  tribe  is  economically  important  as 
many  of  its  members  are  weeds  ( Anthemis  cotula  L.),  cultivated  ( Dendranthema  species)  or  used 
medicinally  ( Artemisia  afra  Jacq.  ex  Willd.). 

The  last  revision  of  Eriocephalus  and  Lasiospermum  in  southern  Africa  was  done  by  Harvey  (1865, 
in  Flora  capensis  3).  The  genus  Eriocephalus  is  endemic  to  southern  Africa  and  its  distribution 
covers  the  whole  FSA  region  except  Gauteng  and  KwaZulu-Natal,  with  the  highest  concentration 
of  taxa  in  the  Western  Cape.  It  is  an  important  member  of  the  karoo  vegetation  and  often  forms  an 
important  fodder  plant  in  these  dry  areas  (Van  Breda  & Barnard  1991,  100  Veld  plants  of  the  win- 
ter rainfall  region.  A guide  to  the  use  of  veld  plants  for  grazing-,  Le  Roux,  Kotze,  Nel  & Glen  1994, 
Bossieveld). 

Except  for  Lasiospermum  brachyglossum  DC.  var.  sinaicum  Asch.  & O.Hoffm.  (this  should  prob- 
ably rather  be  treated  as  a subspecies),  which  occurs  in  the  Sinai  Desert,  the  genus  Lasiospermum 
is  endemic  to  southern  Africa  and  its  distribution  covers  Namibia,  North-West,  Gauteng,  the  Free 
State,  Lesotho  and  the  Northern,  Western  and  Eastern  Cape.  It  is  economically  important  as  some 
members  are  reported  to  be  poisonous  to  stock  (Walsh  1909,  South  African  poisonous  plants', 
Vahrmeijer  1981,  Poisonous  plants  of  southern  Africa  that  cause  stock  losses). 

Members  of  Eriocephalus  display  anomalous  secondary  growth,  which  leads  to  the  splitting  of 
older  plants  resulting  in  independent  daughter  plants  (Muller  1988).  The  branches  can  be  divided 
into  long,  ‘normal’  branches  (dolichoblasts),  with  leaves  either  opposite  or  alternate,  and  dwarf 
shoots  (brachyblasts)  containing  leaf  tufts.  The  most  important  characters  used  in  the  delimitation 
of  species  are:  paleae  of  marginal  female  florets  free  or  connate,  capitula  radiate  or  disciform,  the 
indumentum  of  the  leaves  felty  or  sericeous  and  leaves  opposite  or  alternate.  Until  now  it  was 
believed  that  the  involucre  consisted  of  two  rows  of  involucral  bracts  (De  Candolle  1838, 
Prodromus  systematis  naturalis  regni  vegetabilis  6;  Harvey  1865;  Bentham  1873,  in  Genera  plan- 
tarum  2;  Phillips  1926,  The  genera  of  South  African  flowering  plants’,  Merxmiiller  1967,  in 
Prodromus  einer  Flora  von  Siidwestafrika  139;  Bremer  & Humphries  1993,  in  Bulletin  of  the 
Natural  History  Museum,  London  (Botany  series)  23,2;  Bremer  1994).  Muller  ( 1988)  conducted  an 
intensive  ontogenetic  and  anatomical  investigation  of  the  capitula  and  came  to  the  conclusion  that 
the  involucre  consists  of  only  one  row  of  involucral  bracts  and  that  the  inner  row  represents  the 
paleae  of  the  marginal  female  florets.  These  paleae  can  be  either  free  or  connate. 

Herman  (2001,  in  South  African  Journal  of  Botany  67:  66)  described  septate  hairs  on  the  paleae  of 
most  of  the  Eriocephalus  species  and  on  the  cypselas  of  two  of  the  four  Lasiospermum  species  and 
it  seems  possible  that  these  hairs  could  be  a generic  character  of  both  Eriocephalus  and 
Lasiospermum.

Erect,  many-stemmed,  freely  branched, 
weakly  woody  shrubs  or  suffrutices,  with  annual 
regrowth,  35CM-50  mm  tall,  350  mm  in  diame- 
ter. Old  stem  not  displaying  anomalous  second- 
ary growth,  cylindrical,  grey-yellow;  young 
shoots  golden  brown,  densely  long-pilose  mixed 
with  dense  felty  indumentum,  pubescence  per- 
manent; brachyblasts  absent;  dolichoblasts  leafy, 
without  cushion-like  thickenings  on  stems. 
Leaves  alternate,  distinctly  petiolate;  lamina 
20-75  mm  long,  pinnatisect,  3-7-lobed;  lobes 
linear,  up  to  48  x 1.0-1. 5 mm,  adaxially  basally 
flattened  to  concave,  abaxially  convex;  perma- 
nently grey-golden  hairy,  indumentum  sparsely 
long-pilose  mixed  with  felty  mat;  petiole  slight- 
ly broadened  at  base,  temporarily  retained  after 
leaf  fall,  abscising  later.  Capitula  heterogamous 
radiate,  mostly  racemose  or  in  umbellate  termi- 
nal racemes,  rarely  solitary  in  leaf  axils,  rela- 
tively large,  10-12  x 5-15  mm;  peduncles 
cylindrical,  15-46  mm  long,  densely  felty. 
Involucral  bracts  5,  10-13  x 4-6  mm,  with 
abaxially  hairy,  central,  green,  herbaceous  strip 
and  relatively  broad,  glabrous,  membranous 
margins.  Paleae : those  of  marginal  florets  con- 
nate into  hard  cylindrical  sheath,  8-10  mm 
long,  margin  densely  lanate,  hairs  septate;  those 
of  disc  florets  spathulate  to  linear,  membranous, 
6-8  mm  long,  abaxially  densely  lanate,  indu- 
mentum intertwined  with  that  of  neighbouring 
paleae  to  form  a mat,  apex  fringed.  Ray  florets 
female,  4—8.  6-10  mm  long,  lamina  broadly 
cuncate.  6x5  mm,  golden  yellow,  3-lobed, 


abaxially  glandular,  longer  than  style  branches. 
Style  forked,  branches  flattened,  linear.  Ovary 
(and  cypsela)  oblong,  lanceolate,  long-pilose/ 
lanate.  Seed  5-6  mm  long,  flatfish  trigonous. 
Disc  florets  functionally  male  with  sterile  ovary, 
30-60;  corolla  tube  cylindrical  to  trumpet- 
shaped, 5-lobed,  golden  yellow.  Style  un- 
branched, cylindrical,  apex  globose,  with 
sweeping  hairs.  Stamens  5,  exserted  at  maturity. 
Receptacle  after  anthesis  with  long  hairs 
between  involucral  bracts  and  marginal  connate 
paleae.  Chromosome  number.  In  = 18.  Flower- 
ing time : March  to  May,  sometimes  continuing 
into  August;  flowering  is  linked  to  rainfall, 
which  can  be  fairly  sporadic  in  the  distribution 
range. 

This  Namibian  endemic  occurs  in  the  north- 
ern and  central  Narnib,  on  the  escarpment  and 
mopane  savanna  (Giess  1971).  These  areas  re- 
ceive an  average  annual  rainfall  of  less  than  200 
mm.  Although  the  distribution  of  this  species 
extends  over  a large  area,  plants  are  extremely 
scarce  and  occur  fairly  localised.  They  are  usu- 
ally found  in  groups  of  five  to  eight  but  some- 
times of  up  to  20  plants.  They  grow  mostly  in 
stony  areas  or  on  sandstone  koppies.  Map  1 . 

E.  pinnatus  is  unique  in  the  genus  in  more 
ways  than  one.  It  has  distinctly  pinnatisect 
leaves,  large  golden  yellow  ray  florets  and  is 
herbaceous — all  characters  not  found  in  the  rest 
of  the  genus.  The  whole  plant  is  covered  by  an 
indumentum  of  dense  golden  grey  felt  inter- 
spersed with  scattered  long-pilose  hairs.  Some 
other  species  of  the  genus  also  have  a felty 
indumentum,  but  it  consists  mostly  of  tempo- 
rary, fine,  soft,  white  hairs.  Where  a permanent 
felty  indumentum  occurs,  it  is  more  felty 
sericeous.

Map  i . — • Eriocephalus  pinnatus;  ▲ E.  macroglossus; 

■ E.  capitellatus. 

Pinnatisect  leaves  are  not  uncommon  in  the 
genus  Eriocephalus , but  the  degree  of  incision 
reaches  its  peak  in  this  species.  E.  pinnatus  has 
a distinct  petiole  and  a blade  with  3-7  lobes. 
The  stems  are  mostly  herbaceous,  woody  at 
base  only.  Anomalous  secondary  growth  is 
absent  only  in  this  species  and  in  E.  longifolius 
(no.  5).  The  plant  is  browsed  to  the  ground  or 
above-ground  parts  die  back  every  year  and 
resprout  after  first  good  rains.  It  is  the  only 
species  with  golden  yellow  ray  florets.  Yellow 
disc  florets  are  present  inter  alia  in  E.  lueder- 
itzianus  (no.  25)  and  E.  ambiguus  (no.  24)  and 
pale  yellow  to  cream-coloured  rays  in  E. 
macroglossus  (no.  2).  Although  each  capitulum 
contains  4—8  female  florets,  very  few  cypselas 
are  formed.  From  10  capitula  with  probably  60 
female  florets,  only  two  mature  seeds  were 
observed,  thus  a seed-set  of  only  3%.  This  pos- 
sibly explains  the  scarcity  of  this  species.

E.  macroglossus  is  currently  known  only 
from  northern  Namaqualand.  The  record  from 
Botterkloof  Pass  is  doubtful  since  the  fragment 
was  mounted  with  material  of  E.  purpureus 
( Barker  9293,  NBG).  An  attempt  to  locate  it  in 
that  area  proved  to  be  unsuccessful.  The  plants 
are  found  ± 600  m above  sea  level  on  low 
mountains  in  stony  soil.  Its  distribution  falls 
into  Acocks’s  (1975)  Namaqualand  Broken 
Veld.  Map  1. 

The  species  is  distinguished  by  its  leaves 
with  a silvery  sericeous  indumentum,  umbellate 
racemes,  large  capitula  with  distinct,  large, 
cream-coloured  (pale  yellow)  rays  and  well- 
developed  long-lanate  indumentum  in  the  capi- 
tula. It  is  closely  related  to  E.  grandiflorus  (no. 
15).  The  latter  is  a much-branched,  slightly 
spinescent  shrub  with  pure  white  or  pale  to  dark 
purple  rays,  whereas  E.  macroglossus  is  not 
spinescent  and  has  pale  yellow  rays.

E.  capitellatus  occurs  on  the  high  mountains 
of  the  Western  and  Eastern  Cape.  It  grows  at  an 
altitude  of  over  900  m in  both  winter-  and  sum- 
mer-rainfall areas.  The  species  never  occurs  in 
dense  stands  and  is  sparsely  distributed  on 
mountain  slopes.  Map  1 . 

This  shrub  with  its  slender  branches  has 
blue-green  to  grey-green  leaves,  which  turn 
darker  upon  drying.  The  pinnatisect  to  palmati- 
sect leaves  have  extremely  narrow  lobes 
(0.4-0. 6 mm).  While  other  species  of 
Eriocephalus  are  very  attractive  during  flower- 
ing and/or  fruiting,  this  species  is  not  very  con-

To  date,  E.  longifolius  has  been  collected 
only  on  the  Soutpansberg  and  Waterberg  in  the 
Northern  Province.  It  grows  only  on  mountain 
tops,  above  1 700  m,  and  forms  part  of  Acocks’s 
(1975)  Sour  Bushveld.  It  probably  also  occurs 
on  high  mountains  in  Mpumalanga  and  North- 
West.  Although  fairly  rare,  the  species  is  not 
endangered.  Very  few  young  plants  were  seen. 
Most  individuals  in  each  community  (±  15) 
were  already  a few  years  old.  The  percentage 
female  florets  producing  fruit  is  low:  less  than 
10%  (86  capitula,  with  two  or  three  female  flo- 
rets each,  produced  only  19  seeds).  Map  2. 

E.  longifolius  is  distinguished  from  all  other 
species  by  the  long,  acicular,  alternate  leaves 
and  the  sparsely  branched,  regularly  thickened 
stems.  In  nature,  branching  occurs  only  when  an 
inflorescence  is  formed.  The  umbellate  racemes 
develop  terminally  on  stems  and  side  branches 
develop  below  this.  If  the  upper  part  of  the  stem 
is  damaged,  the  stem  resprouts  from  the  base.

The  distribution  of  E.  purpureus  is  restricted 
to  the  winter-rainfall  area  and  extends  from 
Loeriesfontein  southwards  to  Matjiesfontein  in 
mountainous  regions  above  300  m.  The  eastern 
boundary  of  its  distribution  overlaps  with  the 
western  distribution  of  E.  ericoides  (no.  26). 
Map  3. 

A.',  purpureus  has  distinct,  large,  pale  to  dark 
purple,  strap-shaped  ray  florets,  which  easily 


distinguish  it  from  related  species.  However, 
sterile  and  fruiting  material  presents  problems 
in  identification  as  it  closely  resembles  E.  eri- 
coides (no.  26).  If  no  remains  of  the  ray  florets 
are  present,  the  two  species  can  be  distin- 
guished by  the  connate,  marginal  paleae  form- 
ing a hard,  cylindrical,  coriaceous  sheath  in  E. 
purpureus  as  opposed  to  the  short,  yellow,  mar- 
ginal female  florets  and  free,  marginal  paleae  in 
E.  ericiodes. 

Although  E.  purpureus  had  already  been 
described  in  1822  by  Burchell  from  material 
collected  in  the  Windheuvel-Koedoesberg,  it 
was  later  mentioned  by  Don  (1830)  only  as  a 
plant  known  to  British  gardeners.  De  Candolle 
(1838)  and  Harvey  (1865)  did  not  include  it  in 
their  studies  on  the  genus  Eriocephalus , 
although  E.  decussatus  (no.  21)  and  E. 
spinescens  (no.  30),  two  species  described  by 
Burchell  (1822)  in  the  same  publication,  were 
indeed  included.  Only  after  the  publication  of  E. 
xerophilus  by  Schlechter  (1899),  was  this 
species  noted  and  all  herbarium  material  includ- 
ed under  this  name. 

Leipoldt  760  (BOL,  SAM)  mentioned  that 
this  species  was  a very  valuable  fodder  plant. 
This  can  be  confirmed  by  signs  of  heavy  brows- 
ing visible  on  some  herbarium  specimens.

ASTERACEAE:  Eriocephalus 


Few  herbarium  specimens  could  be  traced 
under  the  name  E.  pedicellaris.  Most  material 
was  found  under  E.  punctulatus  (no.  9)  or 
misidentified  as  E.  africanus  (no.  14).  Although 
closely  related  to  E.  punctulatus , E.  pedicellaris 
can  be  distinguished  from  that  species  by  the 
long,  blue-green,  succulent  leaves  which  turn 
noticeably  darker  upon  drying,  the  relatively 
large  capitula,  4-5  x 5-8  mm,  on  long  pedun- 
cles, 10-30(^4-0)  mm,  and  by  the  brittle  stems. 
E.  pedicellaris  grows  mostly  at  300-600  m alti- 
tude, but  often  below  300  m,  in  contrast  to  E. 
punctulatus  which  grows  at  and  above  600  m. 

E.  pedicellaris  is  a very  palatable  shrub, 
which  is  heavily  and  selectively  browsed  wher- 
ever it  occurs,  possibly  because  of  its  succulent 
leaves  and  soft  shoots,  in  contrast  to  E.  punctu- 
latus, which  is  hardly  browsed.  Common  name: 
kapokbos.

Erect,  much-branched  shrubs  up  to  0.6  m 
high.  Old  stems  and  branches  dark  brown,  lon- 
gitudinally grooved,  displaying  anomalous  sec- 
ondary growth,  glabrous,  rigid;  young  shoots 
red-brown,  thin,  straight,  internodes  relatively 
long,  initially  felty,  glabrescent  except  for 
dense,  white  felt  in  leaf  axils.  Leaves  decussate, 
oblong  to  linear-oblong,  2^4(-9)  x 0.3-0. 6 mm, 
entire,  basally  broadly  amplexicaul,  adaxially 
basally  concave,  slightly  flattened  towards

cavities,  shiny,  glabrous  except  for  felty,  axil- 
lary buds,  apex  mucronate;  leaves  of 
dolichoblasts  and  brachyblasts  of  same  size  and 
shape,  those  of  brachyblasts  imbricate.  Capitula 


heterogamous  radiate,  racemose  or  umbellate- 
racemose,  small,  4.0  x 3.5  mm;  peduncles 
3— 5(— 1 2)  mm  long,  glabrous  to  sparsely  shortly

female;  corolla  white,  up  to  6.5  mm  long;  lami- 
na up  to  3 mm  long,  broadly  cuneate,  3-lobed, 
with  or  without  glands.  Style  branches  at  most  1 
mm  long,  tapering  (acuminate),  only  apices 
exserted.  Ovary  (and  cypsela)  oblong-ovoid. 
Seed  slightly  flattened,  obovoid,  up  to  3 x 1 
mm.  Disc  florets  13-18,  functionally  male  with 
sterile  ovary,  3-4  mm  long;  corolla  infundibuli- 
form,  distal  widened  part  red-purple,  5-lobed, 
lower  part  yellow.  Stamens  5,  ± as  long  as 
corolla  tube  or  exserted  only  up  to  0.5  mm. 
Style  truncate.  Receptacle  after  anthesis  densely 
long-sericeous  between  involucral  bracts  and 
connate  marginal  paleae.  Chromosome  number: 
2 n - 18.  Flowering  time:  (May  to)  June  to 
October  (to  November),  correlated  with  rainfall 
which  varies  in  this  area  from  350-600  mm  per 
annum. 

E.  aromaticus  is  restricted  to  the  mountains 
of  the  winter-rainfall  area  of  the  Western  and 
Eastern  Cape,  higher  than  900  in  above  sea 
level.  It  never  occurs  in  dense  stands,  but  is 
rather  sparsely  distributed.  The  distribution  of 
E.  aromaticus  and  E.  punctulatus  (no.  9),  a 
related  species,  overlaps  only  in  the  Witteberg 
and  Klein  Roggeveld  Mountains.  Map  4. 

In  the  past,  E.  aromaticus  was  often  con- 
fused with  E.  punctulatus,  a closely  related 
species.  It  can  be  easily  distinguished  from  that 
species  by  the  consistently  opposite  leaves, 
even  on  flowering  shoots.  On  brachyblasts  the 
leaves  are  distinctly  decussate.  The  otherwise

glabrous  leaves  have  a felty  floccose  indumen- 
tum in  the  axil.  In  his  original  description, 
Smith  (1931)  mentioned  that  the  paleae  of  the 
marginal  florets  were  free.  Although  they  look 
free  superficially,  a thorough  study  showed  that 
they  are  connate  from  the  base  for  about  one 
third  of  their  length.

ber. 2 n = 36.  Flowering  time : correlated  with 
rainfall,  May  to  October  with  a peak  from  July

The  distribution  of  E.  punctulatus  extends 
from  Springbok  in  the  Northern  Cape  along 
the  western  parts  of  the  Western  Cape  (the 
Roggeveld  and  Witteberg  Mountains)  where  it 
overlaps  with  the  related  E.  aromaticus  (no. 
8).  It  is  found  mostly  in  high-lying  mountain- 
ous localities,  above  300  m altitude.  Although 
the  distribution  is  limited  to  the  winter-rainfall 
area,  there  are  indications  that  the  amount  of 
rain  influences  the  growth  form.  In  veld  types 
such  as  Namaqualand  Broken  Veld,  Succulent 
Karoo  and  Mountain  Renosterbosveld  (Acocks 
1975)  with  an  annual  rainfall  of  200  mm  and 
less,  slender,  rigid,  erect  shrubs  with  relative- 
ly short  leaves  (2-7  mm  long)  and  often  shiny, 
red  stems  are  found.  In  veld  types  with  an 
annual  rainfall  of  more  than  200  mm,  for 
instance  Fynbos  and  Coastal  Renosterbosveld 
(Acocks  1975),  a strongly  branched,  slightly 
spreading,  open,  bushy  shrub  with  relatively 
long  leaves  (4-28  mm  long)  and  long,  droop- 
ing shoots  is  found.  However,  these  two  forms 
cannot  be  separated  from  each  other  as  there 
is  no  clear-cut  transition.  Map  5.

Map  5. — ■ Eriocephalus  punctulatus;  • E.  tenuifolius. 

In  E.  punctulatus  the  subtending  leaves  are 
shorter  than  the  peduncle  and  therefore  the 
umbellate  racemes  are  very  obvious.  In  con- 
trast. in  the  closely  related  E.  tenuifolius  (no. 
10)  the  subtending  leaves  are  as  long  as  or 
longer  than  the  peduncles,  which  are  thus  hid-

has  mostly  7-10  disc  florets  while  E.  tenuifolius 
has  mostly  13-22.

Although  E.  tenuifolius  is  closely  related  to 
E.  punctulatus  (no.  9),  the  two  species  can  be 
separated  by  their  leaf  size,  peduncle  length,  the 
length  of  the  subtending  leaves  of  the  peduncles 
and  their  distribution.  A further  distinguishing 
character  is  the  fact  that  E.  punctulatus  is  hard- 
ly browsed  in  contrast  to  E.  tenuifolius,  which  is 
heavily  browsed  (Smith  1966). 

In  the  past,  the  leaves  were  used  as  substitute 
for  buchu  by  the  Griquas,  hence  the  common 
name  boegoekapok  (Smith  1966).  Another  com- 
mon name  is  klein-bergkapokbossie.

E.  klinghardtensis  is  restricted  to  the 
Klinghardt  Mountains,  an  isolated  mountain 
range  within  the  Desert  and  Succulent  Steppe 
(Giess  1971)  of  Namibia.  This  region  receives 
an  average  annual  winter  rainfall  of  less  than 
100  mm,  supplemented  by  fog  from  the  ocean 
at  night.  Although  restricted  in  distribution,  this 
sometimes  weakly  spinescent  shrub  is  relative- 
ly common  and  grows  in  association  with  E. 
giessii  (no.  19).  Map  6. 

E.  klinghardtensis  is  closely  related  to  E. 
africanus  (no.  14)  and  E.  scariosus  (no.  13) 
from  which  it  can  be  distinguished  by  the  con- 
sistently opposite  leaves  covered  with  a dense, 
felty  indumentum.

E.  brevifolius  is  one  of  the  more  poorly  col- 
lected species  and  initially  all  the  known  mate- 
rial came  from  Namaqualand.  Its  occurrence  in 
the  Swartruggens-Roggeveld  and  Swartberg 
Mountains  was  subsequently  established  and  it 
is  possible  that  it  has  an  even  wider  distribution. 
It  occurs  at  altitudes  above  900  m,  mainly  in  the 
winter-rainfall  area.  Map  6. 

Although  related  to  E.  africanus  var.  panicu- 
latus  (no.  14b),  it  can  be  distinguished  from  that 
taxon  by  the  dense,  felty,  sericeous  indumentum 
of  the  leaves  resulting  in  a grey-green  appear- 
ance, as  opposed  to  the  silvery  white  appear- 
ance of  E.  africanus  var.  paniculatus.  The  capitu- 
la have  a light  brown,  long-pilose  indumentum 
in  contrast  to  the  white,  long-pilose  indumen- 
tum of  E.  africanus  var.  paniculatus.  E.  afri- 
canus var.  paniculatus  is  hardly  or  not  browsed, 
while  E.  brevifolius  is  readily  browsed  where  it 
occurs.

ASTERACEAE:  Eriocephalus 


The  permanent  short-sericeous  indumentum 
of  the  peduncles  together  with  the  felty 
sericeous  indumentum  giving  the  leaves  a grey- 
green  colour,  shows  a close  relationship  with  E. 
africanus  var.  paniculatus , E.  capitellatus  (no. 
3),  E.  scciriosits  (no.  13)  and  E.  klinghardtensis 
(no.  II).  E.  punctulatus  (no.  9),  on  the  other 
hand,  has  a sparse  felty  indumentum,  glabres- 
cent  with  smooth,  shiny  leaves  and  numerous 
multicellular  glands  in  cavities  on  the  leaf  sur- 
face. The  distinct  large  capitula  of  E.  brevifolius 
(up  to  3.5  mm  long)  with  ( 7—)  1 0—  1 4(—  1 6)  disc 
florets  show  closer  relationship  with  E. 
africanus  var.  paniculatus  Group  IIA  (see  p.  27) 
(up  to  3.5  mm  long)  with  ( 8—)  11—1 4(— 27 ) disc 
florets  than  with  E.  punctulatus  (capitula  up  to 
2.8  mm  long  and  with  7-10  disc  florets).  The 
indumentum  alone  shows  that  E.  brevifolius  is 
not  related  to  E.  punctulatus , but  rather  to  E. 
africanus.  It  is  therefore  incomprehensible  why 
De  Candolle  (1838)  described  E.  brevifolius  as 
a variety  of  E.  punctulatus.

Map  7. — ■ Eriocephalus  scariosus;  • E.  africanus  var. 
africanus. 

E.  scariosus  is  probably  the  most  aromatic 
species  of  Eriocephalus.  The  leaves  are  semisuc- 
culent and,  like  those  of  the  related  E.  africanus 
(no.  14),  have  a very  variable  indumentum.  The 
plants  occurring  furthest  north  in  Namibia,  thus 
within  the  summer-rainfall  zone,  are  relatively 
sparsely  sericeous  to  glabrescent.  Plants  growing 
along  the  Orange  River  within  the  winter-rainfall 
area,  have  a dense,  sericeous  indumentum,  giv- 
ing it  a silvery  white  appearance.  Intermediate 
forms  are  found  scattered  irregularly  throughout 
the  distribution  area.  As  a result  of  the  variation 
in  indumentum,  the  appearance  of  the  plants 
varies  from  bright  green  to  silvery  white.  Similar 
variation  to  that  found  in  the  indumentum  occurs 
in  the  shape  and  length  of  the  lamina  of  the  ray 
floret.  Moore  (1904)  separated  E.  scariosissimus 
from  E.  scariosus  inter  alia  on  the  grounds  of  the 
variation  in  the  lamina  length  of  the  ray  florets. 
They  vary  from  narrowly  to  broadly  oblong,  nar- 
rowly to  broadly  cuneate  and  3-dentate  to  3- 
lobed.  In  fresh  material  the  colour  of  the  rays  is 
pure  white,  but  it  changes  to  bright  yellow  upon 
drying,  as  in  E.  macroglossus  (no.  2). 

Despite  the  strong  aroma  of  E.  scariosus,  it 
is  eagerly  browsed  by  domestic  and  wild  ani- 
mals. Common  name:  kapokbossie.

E.  africanus  is  very  widely  distributed,  oc- 
curring in  a variety  of  vegetation  types.  This 
complex  species  shows  much  variation  in  life 
form,  leaf  shape,  indumentum  and  flower  com- 
position in  capitula,  while  hibridisation  also 
seems  to  occur.  Two  well-demarcated  groups 
can  be  distinguished.  The  one  group  occurs  in 
the  dune  areas  of  the  Coastal  Fynbos,  from  sea 
level  to  about  100  m inland  or  on  rocks  arising 
from  the  sea.  The  plants  therefore  grow  in  soil 
with  a high  salt  content.  They  have  succulent 
leaves  and  a spreading  habit.  The  second  group 


occurs  at  a higher  altitude,  further  inland.  The 
plants  are  more  erect,  with  thin,  slender  stems 
and  nonsucculent  or  only  slightly  succulent 
leaves. 

Two  varieties  are  distinguished: 

Leaves  distinctly  succulent,  3-5-7-lobed 
or  entire,  (6.0— )8.2—  1 5.0(— 34.0)  x 
0.8-2. 5 mm;  shrubs  spreading,  up 
to  4 m in  diameter;  branches  rigid; 

exclusively  coastal 

14a.  var.  africanus 

Leaves  not  or  weakly  succulent,  mostly 
entire,  (5-)8-17(-40)  x 0.4-0.8 
mm;  shrubs  mostly  erect,  0.3-0.6  m 
in  diameter;  branches  flexible; 
inland 14b.  var . paniculatus 

Note:  in  his  thesis,  Muller  (1988)  distinguished 
these  two  taxa  as  subspecies.  It  was  decided, 
however,  to  change  them  to  variety  level  as  they 
occur  in  the  same  geographical  area. 

14a.  var.  africanus. 

Spreading  shrubs  up  to  4 m in  diameter; 
branches  rigid,  up  to  4 mm  thick.  Young  shoots 
red-brown  to  grey-green  depending  on  indu- 
mentum, densely  leafy.  Leaves  mostly  opposite, 
sometimes  even  in  whorls  of  3,  alternate  on 
flowering  shoots,  sessile  on  permanent  cushion- 
like thickening,  (6.0-)8.2-15.0(-34.0)  x 0.8- 
2.5  mm,  palmatisect,  3-7-lobed  or  pinnatisect, 
3-lobed  distally  or  entire,  slightly  widening  dis- 
tally,  succulent,  blue-green  to  grey-green. 
Capitula  terminal,  in  umbellate  racemes,  rarely

Mossel  Bay  to  Knysna.  The  habitat  extends 
from  the  high-water  mark  to  about  100  m inland 
and  on  rocks  arising  from  the  sea.  Map  7. 

The  spreading  habit  and  succulent,  palmati- 
sect,  blue-green  to  green-grey  leaves  with  3-5-7 
lobes  on  firm,  relatively  thick  shoots  (up  to  4 
mm  thick),  are  diagnostic  characters  of  this  vari- 
ety. The  growing  points  are  normally  enveloped 
by  older  leaves,  giving  it  a quadrangular  appear- 
ance. Eastwards  between  Mossel  Bay  and 
Knysna  the  plants  are  not  as  distinctly  succulent 
as  on  the  Cape  Peninsula.  The  leaves  are  slight- 
ly smaller  but  have  the  same  typical  palmatisect 
shape  with  3-5-7  lobes.  The  distribution  areas 
of  var.  africanus  and  var.  paniculatus  overlap 
and  possible  hybrids  were  observed,  e.g.  Tyson 
3048  (NBG),  Tyson  3051  (SAM)  and  Pearson 
225  (NBG).  In  the  case  of  Esterhuysen  32159a 
(BOL),  the  variations  are  clearly  visible. 

Although  this  is  the  oldest  described  species 
of  the  genus  Eriocephalus,  it  is  not  widely 
known  by  the  public  and  has  few  common 
names.  It  has  the  oldest  known  common  name, 
namely  clustery  leaved  scentwort  (Hill  1759). 
Other  common  names  are  kapokbossie  and 
wilde  roosmaryn  (Smith  1966).

The  distribution  extends  mostly  over  the 
winter-rainfall  area.  After  E.  ericoides  (no.  26), 
E.  africanus  var.  paniculatus  is  the  taxon  with 
the  widest  distribution.  It  must  be  regarded  as 
the  taxon  with  most  potential  for  hybridisation, 
as  it  occurs  together  with  so  many  other  species. 
The  distribution  extends  over  the  Northern, 
Western  and  Eastern  Cape.  The  distribution  area 
covers  various  veld  types,  e.g.  Succulent  Karoo, 
Fynbos,  Coastal  Renosterbosveld  and  Fynbos, 
Succulent  Mountain  Scrub,  Karroid  Broken 
Veld,  False  Fynbos,  Knysna  Forest,  Alexandria 
Forest,  Valley  Bushveld,  Noorsveld,  False 
Karroid  Broken  Veld  and  False  Upper  Karoo 
(Acocks  1975).  Such  a large  number  of  differ- 
ent habitats  show  the  potential  of  the  taxon  to 
adapt  to  different  soil  types  and  altitudes.  It  fur- 
thermore grows  in  both  winter-  and  summer- 
rainfall  areas.  Map  8.

Map  8. — Eriocephalus  africanus  var.  paniculatus. 


The  phenotypic  plasticity  of  var.  paniculatus 
is  high.  The  variety  shows  much  variation  in 
habit,  leaf  size  and  shape,  and  degree  of  hairi- 
ness. Some  varying  characters  can  be  ascribed 
to  environmental  influences,  but  others  are 
genetically  determined.  Some  characters  are 
correlated  with  geographic  distribution,  but  at 
this  stage  it  seems  best  not  to  distinguish  formal 
infravarietal  groups  as  the  morphological  varia- 
tion is  continuous  and  it  has  not  been  studied  in 
detail.  The  problem  can  be  solved  only  by  inten- 
sive population  studies.  It  will  be  necessary  to 
cultivate  plants  from  the  different  areas  under 
similar  conditions. 

Based  on  herbarium  and  field  studies,  the 
taxon  can  be  divided  into  the  following  five 
groups. 

Group  I 

Plants  of  this  group  have  glabrescent  leaves. 
The  glabrescence  varies,  even  on  one  plant.  It 
seems  that  leaves  produced  during  dryer  sea- 
sons are  more  densely  sericeous  and  tend  to  be 
less  glabrescent,  while  those  produced  during 
the  active  growing  season  and  flowering  time 
tend  to  be  more  glabrescent.  The  distribution  of 
this  group  is  mainly  along  the  western  interior 
in  the  Calvinia  area,  Vanrhynsdorp  to  Citrusdal, 
with  a few  scattered  localities  like  Paarl  and 


Scheepersrus  in  the  Western  (southern)  Cape 
and  Somerset  East  and  Tarkastad  in  the  Eastern 
Cape.  Chromosome  number.  2 n = 36. 

Group  II 

Two  variants  can  be  distinguished  in  this 
group: 

IIA:  Shrubs  with  early  glabrescent  rigid 
stems,  sometimes  with  a glossy  red-brown  to 
chestnut-brown  colour.  The  leaves  are  fairly 
short,  grey-white  sericeous.  Capitula  are  borne 
on  shortly  pedunculate,  sometimes  almost  ses- 
sile, umbellate  racemes,  alternate,  terminally  on 
shoots.  The  inflorescences  develop  mostly  ter- 
minally on  brachyblasts.  The  colour  of  the  ray 
florets  varies  from  pure  white  to  pale  red-purple 
to  almost  dark  red-purple.  The  distribution  of 
this  group  extends  from  the  low-lying  parts  of 
the  Bredasdorp  coastal  areas  to  the  high-lying 
mountainous  parts  of  the  Hantam,  Cedar, 
Langeberg,  Waboom  and  Swartberg  Mountains. 
Chromosome  number.  2 n = 18. 

IIB:  In  the  Langeberg  Mountains  at  Kog- 
manskloof  and  Baden,  very  slender  shrubs  with 
very  small  leaves  and  almost  sessile  to  shortly 
pedunculate  (1. 5-3.0  mm)  capitula  are  found. 
This  variant  shows  a close  resemblance  to  E. 
capitellatus  (no.  3)  from  which  it  differs  in 
indumentum  and  leaf  shape.  It  might  be  a 
hybrid  between  E.  africanus  (no.  14)  and  E. 
capitellatus.  Chromosome  number:  2 n =18. 

Group  III 

This  group  is  found  in  the  low-lying  areas 
(mostly  below  300  m)  from  Humansdoip  to 
Bushmans  River  mouth  and  inland  to 
Grahamstown.  The  leaves  are  fairly  short  and  of 
the  same  length,  (3.5— )4.2— 7.4(— 1 0.5)  mm  on 
the  entire  plant.  Plants  at  the  coast  have  a 
strongly  flattened  habit.  The  leaves  are  distinct- 
ly silver-white-sericeous.  The  ray  florets  are 
white  and  the  capitula  shortly  pedunculate, 
1 .0— 3.0(— 5.5)  mm,  borne  terminally  in  umbel- 
late racemes  on  flowering  shoots.  With  a few

exceptions,  most  capitula  have  four  involucral 
bracts  and  two  ray  florets.  Chromosome  num- 
ber: unknown. 

Group  IV 

This  group  is  restricted  mainly  to  the  moun- 
tainous regions  of  the  Cape  Peninsula,  namely 
Table  Mountain,  Devil’s  Peak,  Signal  Hill  and 
Muizenberg.  The  plants  are  compact,  much- 
branched,  slightly  spreading,  small  shrubs  with 
long,  nonsucculent  leaves,  densely  silver-white 
appressed  sericeous  in  dense  groups  on  brachy- 
blasts  and  on  young  shoots.  Capitula  are  fairly 
large,  borne  mainly  in  umbellate  racemes  or  in 
pseudopaniculate  racemes.  The  distribution  of 
this  group  borders  on  that  of  E.  africanus  var. 
africanus  (no.  14a)  and  hybridisation  between 
the  taxa  does  occur.  Leaves  of  the  hybrid  indi- 
viduals vary  from  succulent  to  nonsucculent. 
However,  they  all  show  the  slightly  spreading 
habit  of  E.  africanus  var.  africanus.  Chro- 
mosome number.  2 n = 36. 

Group  V 

This  group  is  found  from  the  Cape  Flats  fur- 
ther inland.  The  small  shrubs  have  slender,  thin 
branches  with  sparsely  leafy  dolichoblasts  and 
long  internodes.  The  growing  points  are 
exposed  as  they  are  not  enveloped  by  older 
leaves.  Capitula,  which  are  smaller  than  those 
of  Group  IV  and  with  fewer  rays,  are  densely 
grouped  on  flowering  shoots  on  long-peduncu- 
late, umbellate  racemes  or  terminally  on 
branches  or  brachyblasts  in  pseudopanicles. 
Chromosome  number.  2 n = 36.

Closely  related  to  E.  africanus  (no.  14)  and 
E.  eximius  (no.  4).  Differs  from  E.  africanus  by 
its  larger  leaves,  larger  capitula  with  large  con- 
spicuous ray  florets  and  its  much-branched  rigid 
habit.  It  differs  from  E.  eximius  by  its  peduncu- 
late capitula.

marginal  paleae.  Chromosome  number.  2 n = 36. 
Flowering  time:  mainly  June  to  September,  but 
January  to  March  when  it  rains  in  summer. 

The  distribution  area  receives  mainly  winter 
rain  but  often  also  summer  rain.  E.  tenuipes  is 
restricted  mainly  to  the  high-lying  Langkloof 
Mountains  where  E.  capitellatus  (no.  3)  also 
occurs.  It  seems  that  these  two  species 
hybridise,  but  it  has  to  be  confirmed.  Map  9. 

It  is  surprising  that  Smith  (1931)  considered 
E.  tenuipes  to  be  closely  related  to  E.  punctula- 
tus  (no.  9).  The  sericeous  indumentum  of  E. 
tenuipes  rather  points  to  a close  relationship 
with  E.  africanus  (no.  14),  especially  var.  pa- 
niculatus  (no.  14b).  Some  specimens  of  E. 
africanus  var.  paniculatus  are  also  glabrescent 
like  E.  tenuipes,  but  the  leaf  surfaces  do  not 
have  the  characteristic  rough  appearance  of  E. 
tenuipes.  The  leaves  of  E.  africanus  var.  pa- 
niculatus are  highly  variable  in  length  and 
appear  bright  green  to  silver-white  (depending 
on  indumentum)  upon  drying  as  opposed  to 
those  of  E.  tenuipes  which  are  all  of  the  same 
length  and  change  to  olive-green  or  olive-green- 
brown  upon  drying.

Veld  Transition  (Acocks  1975).  Map  9. 

This  species  is  closely  related  to  E. 
spinescens  (no.  30).  When  Burchell  described 
E.  spinescens  in  1822,  he  only  mentioned  the 
spinescence  and  position  of  capitula,  but  not 
the  ray  florets  and  whether  the  capitula  were 
sessile  or  not  (‘branches  spinescent  terminally. 
Capitula  solitary,  lateral’).  A more  complete 
description  of  E.  spinescens  appeared  in  De 
Candolle  ( 1838).  It  was,  however,  described  as 
a plant  with  capitula  solitary  and  sessile  on  ter- 
minal brachyblasts  and  the  corolla  of  the  ray 
florets  strap-shaped  and  much  longer  than  the 
style.  This  description  of  De  Candolle  was 
partly  made  from  a second  specimen  men- 
tioned by  him,  Drege  6041  (G-DC)  from  the 
Sneeuw  Mountains.  This  specimen  is  actually 
aspecific  and  belongs  to  the  current  E. 
karooicus  (no.  17).  It  cannot  be  assumed  that 
De  Candolle  did  not  see  Burchell’s  specimen 
as  both  are  on  one  herbarium  sheet  housed  in 
the  Herbarium,  Conservatoire  et  Jardin 
botaniques  de  la  Ville  de  Geneve,  under  the 
name  E.  spinescens. 

Harvey  (1865)  made  the  same  mistake  as  De 
Candolle  by,  except  for  the  type  specimen  of  E. 
spinescens  (Burchell  1419)  (G-DC)  and  Drege 
6041  (G-DC)  mentioned  by  De  Candolle,  quot- 
ing Zeyher  279  (NBG)  and  Zeyher  858  (GRA, 
NBG),  which  are  all  aspecific,  under  E. 
spinescens.  The  species  was  classified  under  the 
Phaenogyne  (i.e.  capitula  with  distinct  ray  flo- 
rets, longer  than  the  style  and  involucral  bracts). 
Again  the  description  was  partly  based  on  rays 
from  the  Drege  specimen  and  partly  on  certain 
other  specimens  actually  representing  the  cur- 
rent E.  karooicus. 

This  misinterpretation  by  both  De  Candolle 
and  Harvey  caused  all  the  E.  karooicus  material 
through  the  years  to  be  misidentified  as  E. 
spinescens  (no.  30).  Although  these  two  species 
look  very  similar  superficially,  the  former  can 
easily  be  distinguished  from  the  latter  by  the 
sessile  capitula  and  distinct  ray  florets. 


Although  the  terminal  spines  are  a conspicu- 
ous character  of  E.  karooicus,  during  years  of 
good  rain,  long  shoots  are  produced  without 
these  spines.  Spines  develop  again  later  when 
active  growth  slows  down.  As  mentioned 
before,  spicate  synflorescences  are  sometimes 
produced  terminally  on  young  shoots. 

These  delicate,  spinescent  shrublets  are  very 
similar  to  E.  ericoides  during  the  active  grow- 
ing period.  They  differ  from  that  species  by  the 
green-grey  to  silver-grey,  small,  imbricate 
leaves  looking  remarkably  like  a feather.  From 
this  stem  the  common  names  veerkapok, 
veerkarookapok,  veerkaroo.  In  areas  where  the 
species  occurs,  plants  form  dense  stands  and  are 
eagerly  browsed.  They  are  known  as  excellent 
fodder  (according  to  Dr  M.G.A.  Henrici  as 
quoted  by  Mogg  13620,  PRE).  Smith  4333 
(PRE)  mentioned  that  specimens  collected  by 
Amot  in  1867  near  Colesberg  were  locally 
known  as  wilde  dagga.  Other  common  names 
for  this  species  in  the  Karoo  and  Fauresmith 
area  are:  doringkapok(bossie),  kleinkapok- 
bossie,  kleindoringkapokbos,  silwerkapok- 
bossie,  veerkapok(bossie)  and  volstruiskapok 
(Roux  1984;  Smith  1966).

or  solitary  on  brachyblasts,  3.6-4. 1 mm  long; 
peduncles  2. 3-8. 5 mm  long,  appressed  silver- 
sericeous.  Involucral  bracts  4,  ovate,  1.7-3. 3 x 
0.9-2. 4 mm,  2 slightly  keeled,  opposite, 
enveloping  other  2 flattened  bracts,  green,  mar- 
gin broad,  membranous,  shortly  appressed 
sericeous.  Paleae:  those  of  marginal  florets 
free,  keeled,  margins  fringed,  1 .8-2.5  x 0.6-0. 8 
mm,  each  enveloping  a single  floret  (mostly 
female),  hard,  coriaceous,  abaxially  densely 
long-lanate,  hairs  septate;  those  of  disc  florets 
linear,  fringed,  2.0  x 0.3  mm,  membranous, 
abaxially  lanate.  Ray  florets  (1  or)  2,  1.7-3. 3 
mm  long;  corolla  white  to  red-purple;  lamina 
conspicuous,  irregularly  3-lobed,  (0.8—)  1 .2—2. 1 
mm  long,  ± 2 mm  broad,  obovate.  Style  branch- 
es linear,  0.6-1. 2 mm  long,  much  shorter  than 
lamina  of  ray  floret.  Ovary  (and  cypsela)

obovoid,  slightly  flattish,  trigonous,  shorter 
than  2 mm.  Disc  florets  2-5,  functionally  male 
with  sterile  ovary,  1.6-3. 2 mm  long;  corolla 
trumpet-shaped  to  cylindrical,  5-lobed,  white  to 
creamy  at  base  with  red-purple  margins. 
Receptacle  after  anthesis  with  dense,  white, 
long  hairs  between  involucral  bracts  and  mar- 
ginal paleae.  Chromosome  number.  2n  = 36. 
Flowering  time:  January  to  March  and  some- 
times to  May  in  the  northern  summer-rainfall 
area,  July  to  September  and/or  January  to  April 
in  southern  parts  receiving  winter  and  summer 
rainfall  respectively. 

The  distribution  is  mainly  restricted  to  sum- 
mer-rainfall areas,  although  the  southern 
extremes  of  its  distribution  near  Aus  fall  in  the 
transitional  zone  between  summer  and  winter 


rainfall.  E.  dinteri  is  endemic  to  Namibia  and 
has  a restricted  distribution,  occurring  only  on  a 
few  high  mountains,  e.g.  the  Brandberg,  Auas 
Mountains  and  Aus  Mountains,  above  1 000  m 
altitude.  Population  density  at  the  different 
localities  varies  from  scattered  to  rare,  the  plants 
occurring  nowhere  in  dense  stands.  Map  9. 

Only  a single  record  of  a hybrid  between  E. 
dinteri  and  E.  luederitzianus  (no.  25),  Midler  52 
(WIND),  could  be  positively  identified. 
Hybridisation  may  possibly  occur  between  E. 
dinteri  x E.  merxmuelleri  (no.  32)  and  E.  dinteri 
x E.  ambiguus  (no.  24),  but  it  is  difficult  to  con- 
firm this.

have  been  incorrectly  identified  as  E.  africanus. 
These  misidentifications  can  be  ascribed  to  a 
description  and  associated  illustration  of  E. 
racemosus  by  Gaertner  (1791),  based  on  ma- 


terial of  E.  africanus,  which  were  accepted  by 
Lamarck  (1796)  and  Jacquin  (1796). 

Obvious  differences  in  capitulum  structure 
together  with  differences  in  leaf  shape,  have  led 
to  the  recognition  of  two  varieties.  This  division 
is  supported  by  chromosome  morphology. 

Note:  in  his  thesis,  Muller  (1988)  distin- 
guished these  two  taxa  as  subspecies.  It  was 
decided,  however,  to  lower  them  to  variety  level 
as  they  occur  in  the  same  geographical  area.

20a.  var.  racemosus. 

Leaves  linear.  Capitula  2. 5-3. 5 mm  long, 
sessile  to  very  shortly  pedunculate  (at  most  5 
mm  long).  Paleae : those  of  marginal  florets 
connate,  thin,  membranous;  those  of  disc  florets 
weakly  developed  and  often  absent  in  central 
florets.  Marginal  female  florets  (1)2.  Disc  flo- 
rets (4— )7— 9,  2.4-3. 2 mm  long.  Flowering  time: 
June  to  September,  but  depending  on  rain,  con- 
tinuing until  November.  Figure  7. 

With  a few  exceptions,  var.  racemosus  is 
almost  always  found  near  the  coast.  It  extends 
as  far  east  as  Port  Elizabeth  and  west  to 
Lambert’s  Bay.  Map  10. 

This  variety  forms  a dense,  compact  shrub, 
which  is  densely  leafy  at  branch  tips.  The  syn- 
florescence  is  a dense,  drooping,  spicate 
raceme.  Capitula  are  mostly  sessile.  In  Henrici 
3721  (PRE)  and  Bohnen  409/3  (NBG)  the  capit- 
ula are  shortly  pedunculate  (less  than  5 mm) 
and  they  could  possibly  be  transitional  forms  to 
var.  affinis.  However,  in  both  these  specimens 
the  capitula  contain  fewer  than  10  disc  florets,  a 
feature  which  assigns  them  to  var.  racemosus.

Doubtful  cases  with  shortly  pedunculate  capitu- 
la  can  therefore  be  positively  identified  by  the 
number  of  disc  florets. 

E.  racemosus  var.  racemosus  which  forms 
part  of  the  Coastal  Fynbos  (Acocks  1975),  can 
survive  veld  fires  and  has  become  an  invader  in 
certain  areas.  In  some  areas  it  is  well  browsed 
but  in  other  areas  it  is  not  utilised  at  all.  Ac- 
cording to  Smith  ( 1966)  the  wool  is  used  by  the 
Cape  Penduline  Tit  ( kapokvoeltjie ),  Antho- 
scopus  minutus,  for  making  its  nest,  and  by 
rural  people  for  stuffing  pillows.  Common 
names:  sandveldkapok,  strandveldkapok , rivier-

The  distribution  of  E.  decussatus  extends 
over  both  summer-  and  winter-rainfall  regions, 
over  the  central  Karoo  and  parts  of  Nama- 
qualand,  mostly  on  sandy  soil.  Although  a large 
number  of  capitula  are  produced,  this  species  is 
never  found  in  dense  stands  but  is  rather  scat- 
tered. Map  1 1 . 

E.  decussatus  is  one  of  the  species  that, 
because  of  incomplete  descriptions  coupled 
with  misinterpretations  by  later  researchers, 
kept  taxonomists  on  the  wrong  track.  Burchell 
first  collected  it  in  1811  and  in  1822  a very 
short,  incomplete  description  was  published.  De 
Candolle  (1838)  included  it  in  his  work,  but  in 
synonymy  under  E.  glaber  (=  E.  ericoides),  which 


it  superficially  resembles,  but  from  which  it 
differs  in  indumentum  and  connate  marginal 
paleae.  Despite  its  obscurity  to  taxonomists, 
Don  (1830)  mentioned  it  as  an  ornamental 
known  to  gardeners  in  the  United  Kingdom. 
Harvey  (1865)  did  not  mention  it  in  his  work 
on  Eriocephalus.  Its  synonym  E.  aspala- 
thoides , as  described  by  De  Candolle,  is  better 
known.  It  is  ironic,  however,  that  almost  all 
specimens  identified  with  this  name,  do  not 
belong  to  this  species  but  rather  to  E.  ambiguus 
(no.  24),  E.  luederitzianus  (no.  25),  E.  nama- 
quensis  (no.  31)  or  E.  microphyllus  (no.  28),  all 
taxa  distinct  from  E.  decussatus.  Acocks 
(1975)  had  a realistic  concept  of  this  species 
and  identified  it  correctly  in  most  cases.  The 
main  reason  for  this  confusion  was  Harvey’s 
(1865)  misinterpretation  of  De  Candolle’s 
(1838)  description.  Harvey  (1865)  described 
the  plants  as  subspinescent  while  De  Candolle 
(1838)  explicitly  described  the  plants  as  similar 
to  E.  spinescens  but  almost  without  spines 
(‘sed  rami  subinermes’).  The  spines  referred  to 
by  De  Candolle  are  the  hardened  remains  of  the 
terminal  racemose  peduncles  that  sometimes 
occur  (the  capitula  are  mostly  terminal  on 
brachyblasts). 

Another  misunderstanding  causing  confu- 
sion and  misidentifications  was  De  Candolle’s 
(1838)  description  of  the  leaves  as  opposite  and 
alternate,  which  should  have  been  opposite  with 
alternate  leaves  on  flowering  shoots.  Neither 
Burchell  (1822)  in  his  original  description  of  E. 
decussatus,  nor  De  Candolle  (1838)  in  his 
description  of  E.  aspalathoides,  mentioned  the 
connate  paleae  of  the  marginal  florets,  the  most 
important  character  distinguishing  this  taxon 
from  the  closely  related  E.  microphyllus. 

Where  E.  decussatus  and  E.  microphyllus 
occur  together,  they  resemble  each  other  in 
habit,  but  can  be  distinguished  by  the  silvery 
sericeous  indumentum  in  E.  decussatus,  giving 
the  plants  a silvery  grey  appearance,  as  opposed 
to  the  blue-green  to  grey-green  to  bright  green 
colour  of  E.  microphyllus.

E.  kingesii  is  endemic  to  Namibia  and  its  dis- 
tribution is  limited  to  Liideritz  and  Diamond 
Area  No.  1,  which  falls  in  the  winter-rainfall 
region  of  the  Desert  and  Succulent  Steppe 
(Giess  1971).  Most  localities  are  near  the  coast 
and  are  subject  to  fog  at  night.  The  average 
annual  rainfall  of  this  area  is  less  than  50  mm. 
Map  11. 

These  rigid,  flat,  spreading  shrubs  with 
entire,  succulent,  silvery  sericeous  leaves  are 
fairly  common  in  the  areas  where  they  occur. 
This  is  the  only  Eriocephalus  species  with  a 
high  seed  set  (90%)  and  germination  percent- 
age. At  a temperature  of  28°C,  16  of  20  seeds 
germinated  within  4 days — thus  a germination 
percentage  of  80%. 

Since  succulence  in  coastal  habitats  is  often 
regarded  as  being  determined  by  environment, 
young  and  mature  plants  were  cultivated  under 
uniform  conditions  at  the  Botanical  Garden  of 
the  University  of  Stellenbosch.  Succulence 
remained,  leading  to  the  conclusion  that  it  is 
genetically  determined  in  this  species  as  is  the 
case  in  E.  africanus  var.  africanus  (no.  14a), 
which  also  occurs  along  the  coast.

Map  12. — Eriocephalus  pauperrimus. 

The  distribution  of  E.  pauperrimus  extends 
from  the  southern  parts  of  Namibia  through  the 
Northern  Cape  to  Matjiesfontein  in  the  Western 
Cape.  The  areas  where  it  occurs,  receive  less 
than  200  mm  rain  per  annum.  It  occurs  mainly 
in  the  summer-rainfall  area  but  also  partly  in  the 
area  that  receives  both  summer  and  winter  rain 
at  an  altitude  of  300-600  m.  This  species  is 
under-collected  in  southern  Namibia  and  the 
Northern  Cape.  Map  12. 

Although  closely  related  to  E.  ericoides  (no. 
26),  it  can  easily  be  distinguished  from  that 
species  by  the  alternate  leaves  and  sessile  ca- 
pitula in  terminal  spikes.

43 


Many-stemmed,  erect,  much-branched,  spi- 
nescent  shrubs,  0.3-0. 6 m high  and  up  to  450 
mm  in  diameter.  Older  stems  with  grey-brown 
bark,  deeply  grooved,  eventually  displaying 
anomalous  secondary  growth,  10-20  mm  in 
diameter,  breaking  up  into  independent  daugh- 
ter plants;  young  branches  yellow-brown,  later 
yellow-grey  to  grey-brown,  irregularly  sympo- 
dially  branched,  tips  of  branches  spinescent, 
1-18  mm  long;  brachyblasts  1-10  mm  long, 
short-lived.  Leaves  basally  semilunate,  adaxial- 
ly  concave,  those  on  dolichoblasts  alternate, 
linear,  4-15  x 0.5  mm,  entire,  densely  silver- 
grey  shortly  pilose  to  pilose,  apex  obtuse; 
leaves  on  brachyblasts  scale-like,  rosulate,  2-4 
x 0.5  mm,  entire,  apex  obtuse.  Capitula  hetero- 
gamous  disciform,  4 mm  long,  solitary  on 
brachyblasts,  rarely  in  terminal  racemes;  pedun- 
cles 1-11  mm  long,  shortly  pilose.  Involucral 
bracts  4 or  5,  2.5  x 1 .5  mm,  green,  with  narrow, 
sometimes  purplish,  membranous  margin, 
ovate,  flattened,  abaxially  appressed  sericeous. 
Paleae:  those  of  marginal  florets  free,  2 x 1.5 
mm,  keeled,  lanceolate,  apices  fringed,  abaxial- 
ly long-pilose,  hairs  septate,  adaxially  smooth, 
glabrous;  those  of  disc  florets  oblong-linear, 
membranous,  apex  fringed,  1 x 0.5  mm,  abaxial- 
ly long-pilose,  adaxially  smooth.  Marginal 
female  florets  2-5,  yellow,  inconspicuous, 
2.0-2. 5 mm  long;  lamina  absent;  corolla  tubular- 
filiform,  much  shorter  than  branched  style.  Style

red-purple.  Stamens  5,  exserted  at  maturity. 
Style  unbranched,  globose,  truncate  with  short, 
sweeping  hairs.  Receptacle  after  anthesis  with 
long,  soft  hairs  between  involucral  bracts  and 
marginal  paleae.  Chromosome  number.  2n  = 18. 
Flowering  time:  January  to  April. 

The  distribution  of  E.  ambiguus  extends 
from  the  central  parts  of  Namibia  to  Botswana 
and  the  Northern,  Western  and  Eastern  Cape. 
Its  current  known  distribution  in  Botswana  is 


nus. 


limited  to  a single  locality  on  the  border 
between  the  Northern  Cape  and  Botswana.  The 
largest  part  of  the  distribution  area  receives  an 
annual  rainfall  of  less  than  200  mm;  only  the 
southernmost  part  of  its  distribution  receives  an 
average  annual  rainfall  of  more  than  200  mm. 
It  is  suspected  that  this  species  is  more  com- 
mon in  the  southern  parts,  but  that  it  has  been 
under-collected  here  because  of  its  similarity  to 
and  the  resulting  confusion  with  E.  karooicus 
(no.  17)  and  E.  spine scens  (no.  30),  both  of 
which  are  associated  with  E.  ambiguus  in  this 
area.  Like  E.  karooicus  and  E.  spinescens,  E. 
ambiguus  is  found  only  in  low-lying  areas,  ± 
300  m above  sea  level,  mainly  in  sandy  and 
clayey  soils,  never  on  mountains  or  hills.  Plants 
are  scattered  or  at  most  found  in  small  groups, 
but  never  form  dense,  dominant  communities. 
Map  13. 

After  the  description  of  E.  aspalathoides  var. 
ambiguus  by  De  Candolle  (1838),  this  taxon 
was  not  recognised  by  later  researchers  of  the 
genus  Eriocephalus.  This  can  be  attributed  part- 
ly to  the  fact  that  later  researchers  like  Harvey 
(1865)  and  Merxmiiller  ( 1967)  placed  it  in  syn- 
onymy under  E.  aspalathoides  and  partly  to  its 
poor  representation  in  herbaria.  It  is  only  from 
1963  onwards  that  this  taxon  has  become  better 
represented  in  herbarium  collections.

ASTERACEAE:  Eriocephalus 


E.  ambiguus  was  confused  with  the  earlier 
known  E.  aspalathoides,  now  E.  decussatus 
(no.  21).  Although  E.  decussatus  has  opposite 
leaves,  they  are  alternate  on  flowering  shoots, 
as  in  E.  ambiguus.  The  capitula  are  solitary, 
pedunculate  on  brachyblasts,  while  the  terminal 
raceme  branches  harden  to  form  spinescent  tips 
after  the  capitula  have  been  shed.  A thorough 
investigation  of  E.  ambiguus  showed  that  the 
leaves  are  always  alternate,  and  a true  spine  is 
formed,  not  merely  spinescent  branch  tips. 

Although  closely  related  to  E.  luederitzianus 
(no.  25),  it  can  be  easily  distinguished  from  that 
species  by  the  spines,  the  capitula  borne  mainly 
on  brachyblasts  and  the  much-branched  growth 
form.  E.  luederitzianus , in  contrast,  has  mainly 
terminal  racemes  of  which  the  central  flowering 
axis  becomes  hardened  and  spinescent  after 
maturity  and  shedding  of  capitula. 

During  good  rainy  seasons  E.  ambiguus 
tends  to  form  long,  drooping  shoots  without 
spines  and  with  long  leaves  similar  to  those  of 
E.  luederitzianus  instead  of  the  typical  spines- 
cent habit  with  rigid  branches  and  very  short 
leaves.  This  variation  of  E.  ambiguus  can  easily 
cause  confusion  with  E.  luederitzianus,  but  as 
these  two  species  are  allopatric,  all  material  can 
be  separated  on  distribution  alone. 

Note:  during  preparation  of  the  manuscript 
and  investigation  of  the  taxa,  Herman  found 
three  specimens  in  PRE  ( Hafstrom  & Acocks 
1554,  Shearing  558 , Van  Rooyen  & Bredenkamp 
168)  in  which  the  paleae  of  the  marginal  female 
florets  were  connate.  No  other  differences  could 
be  detected  in  these  three  specimens;  they  fit  the 
description  of  E.  ambiguus  perfectly,  except  for 
the  connate  paleae.

E.  luederitzianus  occurs  only  in  the  summer- 
rainfall  area.  It  extends  over  the  northern  half  of 
Namibia,  most  of  Botswana  into  the  Northern 
Province  of  South  Africa.  In  Namibia  it  is  the 
most  abundant  species  with  the  widest  distribu- 
tion. Information  from  Botswana  is  very  defi- 
cient, but  it  seems  that  with  the  exception  of  a 
single  locality  for  E.  ambiguus  (no.  24),  this  is 
the  only  species  occurring  in  Botswana.  It  is 
also  possible  that  this  species  is  more  abundant 
in  Botswana,  but  that  it  has  been  under-collect- 
ed until  now.  Map  13. 


As  there  is  so  much  confusion  between  E. 
ambiguus  (no.  24)  [E.  aspalathoides  pro  parte 
after  De  Candolle  (1838),  Harvey  (1865)  and 
Merxmuller  (1967)],  E.  luederitzianus,  E.  micro- 
phyllus  var.  pubescens  (no.  28b)  and  E.  merx- 
muelleri  (no.  32),  a comparison  between  these 
species  is  given  in  Table  1. 

During  good  rainy  seasons  E.  ambiguus  pro- 
duces water  shoots  with  long  leaves  and  lacking 
characteristic  spines.  This  material  can  easily  be 
confused  with  E.  luederitzianus.  Later  growth 
shows  the  characteristic  terminal  spines.  These 
two  species  are  allopatric  and  difficulties 
regarding  positive  identification  can  be  solved 
by  consulting  the  distribution  map. 

In  the  past,  all  material  of  E.  luederitzianus 
was  identified  as  E.  pubescens,  the  current  E. 
microphyllus  var.  pubescens,  because  Merx- 
muller (1967)  had  put  it  into  synonymy  under 
E.  pubescens.  As  a result,  material  of  E.  merx- 
muelleri  and  E.  ambiguus  was  also  identified  as 
E.  pubescens.

E.  ericoides  occurs  from  Namibia  to  the  Free 
State  and  the  Northern,  Western  and  Eastern 
Cape.  The  plants  in  Namibia  are  fairly  isolated 
from  those  in  South  Africa.  Except  for  the  indu- 
mentum of  plants  north  of  the  Orange  River, 
there  seem  to  be  no  obvious  differences  be- 
tween the  plants  in  Namibia  and  those  south  of 
the  Orange  River.  They  all  have  a conical  to 
broom-like  growth  form.  The  shape  and  length

of  the  leaves  differ  very  little  between  the  dif- 
ferent individuals. 

Individuals  from  a population  in  the  North- 
ern Cape,  north  of  the  Orange  River,  have  dull 
green  leaves  with  permanent,  long-felty  hairs. 
In  contrast,  other  individuals  of  the  species  in 
South  Africa  and  Namibia  have  shiny,  bright 
green,  glabrescent  leaves.  On  the  grounds  of  the 
dull  green  leaves  with  permanent,  long-felty 
indumentum  and  geographical  isolation,  this 
group  is  described  as  a subspecies  of  E.  eri- 
coides. 

Two  subspecies  are  recognised:

long.  Marginal  female  florets  (1)2.  Disc  florets 
( 1— )3— 5( — 7).  Flowering  time:  correlated  with 
rainfall,  January  to  April  in  summer-rainfall  areas 
and  July  to  September  in  winter-rainfall  areas. 

E.  ericoides  subsp.  ericoides  has  the  widest 
distribution  of  all  Eriocephalus  taxa.  It  extends 
from  Namibia  into  the  Free  State  and  Northern, 
Western  and  Eastern  Cape,  being  absent  only 
from  the  northwestern  and  western  parts.  The 
species  is  distributed  mostly  inland:  it  does  not 
extend  to  the  coast  and  occurs  mostly  above  300 
m altitude.  The  distribution  includes  both  sum- 
mer- and  winter-rainfall  areas,  ranging  from 
those  with  an  annual  rainfall  of  less  than  250  mm 
to  areas  with  more  than  500  mm.  Compared  to  E. 
africanus  var.  paniculatus  (no.  14b),  the  taxon 
with  the  second-widest  distribution,  occurring  in 
coastal  areas  with  higher  rainfall,  this  subspecies 
is  more  representative  of  the  arid  karoo  region. 
The  disjunct  distribution  of  E.  ericoides  subsp. 
ericoides  is  very  obvious.  Not  only  does  the  pop- 
ulation in  Namibia  stand  isolated  from  the  rest  of

ericoides  subsp.  griquensis. 

the  species  (both  subsp.  ericoides  and  subsp. 
griquensis),  but  there  is  very  little  correlation 
between  the  two  distribution  areas  of  subsp.  eri- 
coides. In  Namibia,  their  habitat  is  high-lying 
mountains,  1 000  to  1 700  m in  altitude,  and 
receives  summer  rainfall  of  only  250  to  300  mm 
rain  annually,  whereas  in  South  Africa  it  occurs 
both  on  high-lying  parts  and  near  the  coast  (300 
m altitude)  and  receives  both  summer  and  winter 
rainfall,  with  a precipitation  of  about  500  mm 
annually.  Both  populations  of  subsp.  ericoides 
occur  in  the  Karoo-Namib  plant  geographical 
region  (Werger  1978).  This  region  is  charac- 
terised by  a wealth  of  dwarf  shrubs  belonging  to 
the  Asteraceae.  Between  this  Karoo-Namib  plant 
geographical  region  and  the  Capensis  region 
where  the  distribution  of  subsp.  ericoides  con- 
tinues. there  are  many  floristic  similarities.  It  is 
therefore  possible  that  E.  ericoides  had  a much 
wider  distribution  earlier  but  that  it  was  disrupt- 
ed by  unknown  factors.  Map  14. 

As  this  subspecies  occurs  in  so  many  differ- 
ent veld  types,  it  has  adapted  to  various  habitats. 
This  in  turn  has  led  to  much  variation  in  mor- 
phological characters.  The  most  common 
growth  form  is  conical  or  broom-like  shrubs 
with  thin  branchlets  and  delicate,  small,  bright 
green,  decussate  leaves  on  brachyblasts.  The 
leaves  at  the  growing  points  of  young  shoots  are

initially  felty,  but  soon  become  glabrous.  The 
growing  points  of  the  brachyblasts  are,  how- 
ever, felty  sericeous. 

The  arrangement  of  capitula  shows  almost  as 
much  variation  as  there  are  plants.  The  most 
common  is  racemose  with  relatively  shortly 
pedunculate  capitula.  Two  specimens  were  col- 
lected by  Tyson  at  Murraysburg:  Tyson  269 
(SAM)  has  an  almost  paniculate  synflores- 
cence,  while  Tyson  289  (SAM)  has  sessile  ca- 
pitula (the  so-called  var.  sessiliflorus  Sond.  ex 
Harv.).  The  leaves  are  mostly  opposite,  but  are 
often  alternate  on  flowering  shoots. 

E.  ericoides  subsp.  ericoides  is  well  browsed 
compared  to  E.  microphyllus  (no.  28).  Accord- 
ing to  Roux  (1984),  this  bush  is  not  unpalatable, 
but  palatability  varies  from  season  to  season.  It 
is  best  utilised  during  late  autumn  and  spring. 
This  subspecies  can  become  invasive  in  dis- 
turbed veld.  Roux  (1984)  mentions  that  it  ham- 
pers the  establishment  of  Panicum  species  in 
the  Karoo  to  a certain  degree.  Common  names:

The  distribution  of  E.  glandulosus  extends 
over  the  Northern,  Western  and  Eastern  Cape, 
in  the  following  Acocks  (1975)  veld  types: 
Kalahari  Thornveld  and  Shrub  Bushveld, 
Kalahari  Thornveld  invaded  by  Karoo,  Orange 
River  Broken  Veld,  Arid  Karoo  and  Desert 
False  Grassveld,  and  False  Arid  Karoo.  These 
areas  receive  an  average  annual  rainfall  of  less 
than  400  mm.  Although  the  species  occurs  over 
a large  area,  it  is  never  found  in  dense  stands, 
but  rather  scattered.  Map  15. 

Closely  related  to  E.  ericoides  (no.  26)  and 
E.  aromaticus  (no.  8)  from  which  it  can  be  dis- 
tinguished by  its  much-branched,  spinescent 
habit,  shiny,  light  green  leaves,  often  with  a red- 
purple  tinge,  and  marginal  female  florets  with 
lamina  about  as  long  as  style  branches. 


Map  15. — Eriocephalus  glandulosus. 

E.  glandulosus  and  E.  ericoides  are  closely 
related,  with  some  similar  characters.  Both 
species  have  decussate,  initially  felty  but  soon 
glabrous  leaves  and  umbellate,  racemose  or 
solitary  capitula,  terminally  on  brachyblasts. 
They  can,  however,  be  distinguished  as  follows: 
the  two  marginal  paleae  of  E.  glandulosus  are 
relatively  broad,  2.0-2. 4 x 1.5  mm,  and  mem- 
branous; the  two  lateral  margins  are  extended  to 
touch  each  other,  thus  enveloping  all  the  florets, 
but  they  are  nonetheless  free.  In  contrast,  the 
marginal  paleae  of  E.  ericoides  are  narrower, 
1. 5-2.0  x 0. 5-1.0  mm,  with  incurved  margins 
so  that  each  envelops  only  one  female  floret 
The  lamina  of  the  marginal  female  floret  is 
absent  in  E.  ericoides  but  fairly  well  developed 
in  E.  glandulosus , as  long  as  to  longer  than  the 
style  branches.

E.  microcephalus  occurs  in  Namaqualand, 
only  above  600  in,  at  the  top  of  mountains  or 
high  on  mountain  slopes,  usually  forming 
dense,  almost  impenetrable  stands.  Where  the 
closely  related  E.  microphyllus  (no.  28)  occurs 
in  the  same  area,  it  grows  at  the  foot  of  moun- 
tains or  in  low-lying  areas,  but  these  two  are  not 
habitat-sympatric.  Map  18. 

Although  closely  related  to  E.  microphyllus 
(no.  28),  E.  microcephalus  can  be  distinguished 
by  the  thin,  small  leaves  0.8-1 .6  x 0.3-0. 5 mm,

ASTERACEAE:  Eriocephalus

The  distribution  area  falls  in  the  transition 
zone  between  winter-  and  summer-rainfall  areas. 
E.  namciquensis  (no.  31),  E.  spinescens  and  E. 
karooicus  (no.  17)  are  allopatric  and  succeed 
each  other  from  west  to  east.  The  distribution  of 
E.  spinescens  extends  from  Calvinia  eastwards 
in  the  Northern  and  Western  Cape.  This  region  is 
very  arid  and  consists  mostly  of  Arid  Karoo  and 
False  Desert  Grassveld  (Acocks  1975),  with  an 
average  annual  rainfall  of  less  than  250  mm.  E. 
spinescens  is  never  found  in  dense  communities, 
although  it  is  fairly  common  in  and  along  water- 
courses and  seasonal  rivulets  and  in  sandy,  grav- 
elly soil.  E.  namaquensis,  on  the  other  hand, 
occurs  mostly  in  high-lying  areas  on  hills  and  in 
stony,  clay  soil.  Map  18. 

De  Candolle’s  (1838)  erroneous  association 
of  Burchell’s  type  material  with  material  from 
the  current  E.  karooicus  (no.  17),  collected  by 
Drege,  resulted  in  most  herbarium  material  of 
E.  karooicus  being  identified  as  E.  spinescens. 
Although  closely  related,  there  are  conspicuous 
differences  (see  discussion  under  E.  karooi- 
cus). 

E.  spinescens  is  a robust  shrub,  up  to  1 m 
high  and  in  diameter,  with  rigid,  strong  spines. 
E.  namaquensis  (no.  31),  another  closely  relat- 
ed species,  is  a delicately  branched  shrub  bare- 
ly 400  mm  tall  and  in  diameter.  The  capitula  of 
E.  spinescens  are  relatively  large,  4.5-5. 2 mm 
long,  and  fairly  shortly  pedunculate,  0-3.5 
(-5.0)  mm  long,  to  almost  sessile,  borne  only 
terminally  on  brachyblasts.  It  is  therefore  easy 
to  distinguish  E.  spinescens  from  the  closely 
related  E.  karooicus  and  E.  namaquensis , which 
are  also  spinescent,  since  E.  karooicus  has  a 
small,  but  distinct  ray  lamina  and  sessile  capit- 
ula and  E.  namaquensis  has  long-pedunculate 
capitula,  solitary  on  brachyblasts,  as  well  as  in 
racemes  borne  terminally  on  dolichoblasts. 

Common  name:  kapokbos.

long-pilose  indumentum  between  involucral 
bracts  and  marginal  paleae.  Chromosome  num- 
ber: 2 n = 18.  Flowering  time:  varying  from  July 
to  October  and  January  to  March  in  the  differ- 
ent rainfall  regions.  Figure  11. 

The  western  part  of  the  distribution  range 
falls  in  the  winter-rainfall  area,  but  summer  rain 
sometimes  occurs  in  the  eastern  part.  The  rain- 
fall is  low,  less  than  200  mm  annually,  and  the 
area  is  often  subject  to  periodic  droughts.  This 
small  shrublet  is  fairly  common  in  the  areas 
where  it  occurs.  It  is  an  important  component  of 
the  Western  Mountain  Karoo  and  the  Succulent 
Karoo  (Acocks  1975).  Map  19. 

E.  namaquensis  grows  in  association  with  E. 
microphyllus  var.  pubescens  (no.  28b),  which  it 
superficially  resembles.  Especially  in  the  west- 
ern part  of  its  distribution  range  where  E. 
namaquensis  is  less  spinescent,  it  is  difficult  to 
distinguish  between  the  two  species  in  their  natu- 
ral habitat.  E.  namaquensis  has  a permanently 
silver-sericeous  indumentum  in  contrast  to  E. 
microphyllus  var.  pubescens  which  is  basically 
felty,  clearly  seen  at  the  growing  point.  As  the 
leaves  age,  the  indumentum  becomes  more 
sericeous,  slightly  wavy,  and  this  can  lead  to 
confusion  with  E.  namaquensis.  If  there  is 
doubt,  the  growing  points  and  peduncles  of  the 
specimen  should  be  examined.  In  E.  microphyl- 


lus var.  pubescens , the  young  leaves  at  the 
growing  points  stick  together  because  of  the 
intertwined  felty  indumentum  of  the  overlap- 
ping leaves.  The  leaves  of  E.  namaquensis  are 
always  free. 

This  species  is  under-collected,  especially  in 
the  southern  Karoo  (Acocks  1975),  partly 
because  these  regions  are  often  subject  to 
drought  and  therefore  under-collected,  and  part- 
ly because  of  confusion  with  species  like  E. 
microphyllus  var.  pubescens  and  E.  decussatus 
(no.  21),  which  it  superficially  resembles.

Eriocarpha  Lag.  ex  DC.:  38  (1838). 


Annual  or  perennial  herbs,  sometimes  decumbent,  rooting  at  nodes.  Leaves  alternate,  long- 
pilose  to  glabrous,  pinnatisect  to  bipinnatisect;  lobes  narrowly  linear,  rarely  entire.  Capitula  pedun- 
culate, terminal,  solitary  or  paniculate,  many-flowered,  homogamous  discoid  or  heterogamous 
radiate.  Involucre  broadly  saucer-shaped;  involucral  bracts  in  2-4  rows,  narrowly  oblong  to  ellip- 
tic to  almost  square,  with  membranous  margin  and  apex,  long-pilose  or  felted  to  glabrous. 
Receptacle  broad,  flat  to  conical  with  membranous  paleae.  Ray  florets  when  present,  few,  female. 
Style  bifurcate,  with  linear,  truncate  branches.  Ovary  oblong.  Pappus  absent.  Disc  florets  numer- 
ous, campanulate;  corolla  5-lobed.  Stamens  5,  anthers  fused,  ecaudate  and  ecalcarate,  with  lanceo- 
late apical  appendage;  endothecial  tissue  polarised.  Style  bifurcate  with  linear,  truncate  branches. 
Ovary  ovoid,  slightly  triangular,  without  any  appendages,  after  anthesis  with  dense,  woolly  indu- 
mentum, hairs  often  septate.  Cypselas  oblong-ovoid,  slightly  flattened,  smooth,  dark  yellow- 
brown.  Pappus  absent.  Basic  chromosome  number,  x = 9 (2 n - 18). 

The  genus  name  Lasiospermum  Lag.  (1816)  is  a later  homonym  of  Lasiospermum  Fisch.  (1812) 
and  should  be  rejected  according  to  Article  64.1  of  the  ICBN.  Cassini  (1822)  was  aware  of 
Lasiospermum  Fisch.,  but  recommended  the  conservation  of  the  name  Lasiospermum  for  Lagasca’s 
genus  as  Fischer  ‘published  only  the  name  without  a description  or  indicating  diagnostic  features; 
therefore  he  (Cassini)  felt  that  the  name  Lasiospermum  should  be  preserved  (retained)  for 
Lagasca’s  genus  and  Fischer’s  genus  should  receive  a different  name’.  As  type  species  he  named 
L.  pedunculare  Lag. 

The  genus  name  Scorzonera  L.  (1735  & 1737)  (Asteraceae)  was  conserved  against 
Lasiospermum  Fisch.  (1812).  Cassini’s  (1822)  motivation  for  the  conservation  of  the  genus  name 
Lasiospermum  Lag.  is  herewith  supported,  especially  as  it  has  been  in  use  for  such  a long  time. 

De  Candolle  ( 1 838)  classified  the  taxa  of  the  genus  Lasiospermum  in  two  sections,  namely  section 
Eulasiospermum  DC.  with  discoid  capitula  and  section  Lanipila  (Burch.)  DC.  with  radiate  capitula. 

According  to  Article  21  of  the  ICBN  (Stafleu  1978):  ‘The  epithet  of  a subgenus  or  section  is  not 
to  be  formed  from  the  name  of  the  genus  to  which  it  belongs  by  adding  the  ending  -oides  or  -opsis, 
or  the  prefix  Eu-.'  The  implication  of  this  rule  means  that  the  section  epithet  Eulasiospermum  as 
published  by  De  Candolle  ( 1 838)  is  invalid.  The  name  Lasiospermum  is  therefore  proposed  for  this 
section  (Article  22,  ICBN). 


ASTERACEAE:  Lasiospermum 


65 


The  section  Lanipila  is  based  on  the  genus  Lanipila  described  from  Burchell  1336  (herbarium 
specimen),  housed  in  Kew.  Treviranus’s  (1826)  description  of  Lasiospermum  radiation , based  on 
the  same  specimen,  does  not  agree  with  the  Kew  specimen,  but  fits  Lasiospermum  bipinnatum. 
Because  of  the  confusion  about  the  identity  of  the  specimen  used  by  Treviranus  for  his  species 
description,  the  use  of  the  name  Lanipila  for  the  section  is  unacceptable  according  to  Article  22 
(ICBN)  as  the  type  of  Lanipila  is  in  the  section  Eulasiospermum.  The  new  name  Radiation 
M. A. N. Muller  is  proposed  for  this  section.

L.  bipinnatum  is  widely  distributed  in  North- 
West,  Gauteng,  the  Free  State,  Lesotho  and  the 
Northern,  Western  and  Eastern  Cape  in  both 
summer-  and  winter-rainfall  regions.  In  some 
areas  it  is  even  regarded  as  a weed  in  agricul- 
tural land.  It  grows  in  dark  brown  sandy  loam, 
sandy  soil,  clay  and  even  dolerite,  with  prefer- 
ence for  moist  areas  like  vleis,  marshes,  river 
banks  and  roadsides  where  pools  of  water  have 
formed.  Map  20.

ASTERACEAE:  Lasiospermum 


Mountains  as  follows:  ‘ Lanipila  C.G.  1336, 
Genus  Cotulae  affine.  Nomen  a lana  et  pila;  ob 
semina  lana  involuta,  et  in  capitulo  spherico 
conglomerata .’  The  holotype  of  the  genus 
Lanipila  (. Burchell  1336 , K!)  was  collected 
between  Jackalsfontein  and  Kuilenberg,  near 
Sutherland.  Treviranus  described  Lasiosper- 
mum  radiation  in  1826  with  'floribus  radiatis’, 
i.e.  with  ray  florets,  and  cited  the  type  as 
Burchell  1336  of  Lanipila  Burch.  The  descrip- 
tion of  Lasiospermum  radiation  agrees  totally 
with  that  of  Lasiospermum  bipinnatum,  al- 
though the  type  at  Kew  on  which  the  descrip- 
tion was  supposedly  based,  represents  Lasio- 
spermum poterioides  Hutch.,  a taxon  described 
only  in  1946.  It  is  concluded  that  the  material  of 
Burchell  used  by  Treviranus  for  the  description 
of  Lasiospermum  radiation  was  not  the  same  as 
the  material  at  Kew. 

Although  the  plants  are  eagerly  browsed  by 
sheep,  Walsh  (1909)  reported  that  it  probably 
caused  animal  poisoning.  This  probability  is 
confirmed  by  notes  on  herbarium  specimens 
and  according  to  Dr  T.F.  Adelaar  (pers.  comm.) 
of  the  Onderstepoort  Veterinary  Institute,  it  con- 
tains a liver  toxin.  According  to  Vahrmeijer 
(1981),  it  causes  photosensitivity.  Inhabitants  of 
the  Middelburg  District  (Eastern  Cape)  make  a 
decoction  of  the  plant  and  use  it  for  affection  of 
the  chest.  The  aromatic  nature  is  apparently 
connected  to  disinfection  as  it  is  used  as  such  by 
the  South-Sotho  in  an  ointment  used  to  disinfect 
a sick  bay  (Phillips  1917). 

The  ray  florets  are  horizontally  orientated  in 
relation  to  the  capitula  during  the  day,  but  they 
are  recurved  at  night  so  that  the  capitulum 
resembles  a shuttlecock.  Ray  florets  are  absent 
in  some  specimens,  e.g.  Compton  10248  (NBG) 
and  Schlechter  8961  (Z).  It  does  happen  spo- 
radically that  rays  are  absent,  giving  rise  to 
incorrect  identifications,  e.g.  as  L.  pedunculare.

Map  22. — Lasiospermum  pedunculare. 


The  distribution  of  L.  pedunculare  in  south- 
ern Africa  is,  with  a few  exceptions,  restricted 
to  the  winter-rainfall  area,  all  along  the  west 
coast.  Until  now,  it  has  been  found  on  sandy, 
loam  and  clay  soils  at  altitudes  of  300-1  500  m. 
Map  22. 

The  works  of  earlier  researchers  like 
Linnaeus  (1763,  1774),  Reichard  (1780)  and 
Desfontaines  (1804)  caused  much  confusion 
about  the  identity  of  Santolina  alpina  L.  and  S. 
erecla  Lam.  The  type  material  of  both  these 
species  originates  from  Italy  and  shows  close 
relationships.  Morphologically  S.  alpina  closely 
resembles  Lasiospermum  pedunculare , except 
for  the  glabrous  cypselas  of  S.  alpina  in  com- 
parison to  the  woolly  cover  of  the  cypselas  of  L. 
pedunculare.  Another  misinterpretation,  which 
has  led  to  further  confusion,  is  the  fact  that 
Linneaus  cited  the  specimen  of  Micheli  as  a 
synonym  of  S.  alpina,  an  error  perpetuated  by 
later  researchers. 

Only  photographs  of  S.  alpina  and  related 
taxa  were  studied.  Another  problem  encoun- 
tered, was  locating  type  material.  It  is  clearly 
mentioned  that  S.  maschalantha  Spreng.  (in 
Schrader  1799,  Journal  fiir  die  Botanik)  was 
described  from  material  ‘Aus  dem  National- 
Museum  zu  Paris’,  but  no  such  material  could 
be  located  there  or  in  other  herbaria.  In  this  spe- 


cific case,  the  description  mentioned:  ‘paleis 
receptaculi  lanatis’,  i.e.  paleae  lanate.  The  prob- 
ability does  exist  that  it  is  the  cypselas  that  are 
lanate,  meaning  that  it  is  a synonym  of 
Lasiospermum  pedunculare.  Santolina  pinnata , 
put  into  synonymy  under  Lasiospermum  pedun- 
culare by  various  earlier  researchers  (Persoon 
1807;  Bertolini  1819;  Don  1839),  originated 
from  southern  Africa  according  to  Donn 
(1800) — the  first  indication  that  the  taxon 
occurs  in  southern  Africa.  In  spite  of  many 
attempts,  the  type  material  of  this  taxon  could 
not  be  located.  A photocopy  of  material  identi- 
fied as  such  from  Liverpool  [Herbarium, 
Merseyside  Country  Museums  (LIV)]  does  not 
agree  with  southern  African  material  at  all. 
Italian  representatives  of  the  species  differ  from 
southern  African  material  by  the  presence  of 
rays  (Bertoloni  1819),  while  southern  African 
specimens  have  discoid  capitula.  Further  confu- 
sion is  added  by  Reichenbach’s  (1831)  descrip- 
tion, stating  that  the  ray  florets  are  white  and 
female  and  that  the  cypselas  are  woolly. 

The  aromatic  smell  of  the  plants  has  led  to 
the  common  names  laventelkatoen  or  lavender 
cotton  by  Donn  (1800).  The  lanate  indumentum 
of  the  cypselas  led  to  the  names  veelvertakte 
wolbol  or  vielspaltige  Wollkugel  (Dietrich 
1817)  and  wolvrug  or  Wollfrucht  (Reichenbach 
1831).  It  is  known  that  the  plants  are  eagerly 
browsed  by  sheep  and  no  poisoning  of  sheep 
has  been  reported  to  date.

solitary,  terminal,  pedunculate,  in  flower  ± 15 
mm  in  diameter,  in  fruit  more  than  20  mm  in 
diameter;  distal  part  of  peduncle  and  involucral 
bracts  felted,  soon  glabrescent.  Involucre  saucer- 
shaped, involucral  bracts  in  3 or  4 rows,  imbri- 
cate, broadly  ovate,  rarely  obtuse-triangular, 
increasing  in  width  from  outer  to  inner,  with 
conspicuous,  broad,  transparent,  membranous 
margin,  up  to  4 x 3.2  mm.  Receptacle  flattened. 
Paleae  broadly  ovate  to  oblong-elliptic,  irregu- 
larly dentate,  transparent,  membranous,  3-4  mm 
long,  outer  many-veined,  inner  with  conspicu- 
ous main  vein.  Disc  florets  ± 250,  bisexual; 
corolla  tubular,  5-dentate  (-lobed),  golden  yel- 
low, turning  red-brown  with  age,  4.0-5. 2 mm 
long.  Stamens  5.  Style  bifurcate,  branches  linear, 
truncate,  with  sweeping  hairs  on  distal  apices. 


Ovary  up  to  2.5  mm  long,  after  anthesis  with 
dense,  woolly  indumentum.  Flowering  time : 
August  to  October. 

This  taxon  is  restricted  mainly  to  the  Suther- 
land District,  the  Berg-Roggeveld  of  the 
Beaufort  clay  series,  with  a single  specimen 
from  Williston  (Northern  Cape).  Map  20. 

L.  poterioides  can  easily  be  confused  with  L. 
pedunculare . The  presence  of  the  felty  indu- 
mentum at  the  tip  of  the  peduncle  and  involu- 
cral bracts,  the  conspicuous,  broad,  transparent, 
membranous  margin  of  the  bracts,  the  leaf  lobes 
that  are  almost  obtuse  and  the  distribution  with 
one  exception  above  1 500  m altitude,  distin- 
guish L.  poterioides  from  L.  pedunculare. 

Common  names  for  this  taxon  are:  gansgras, 
ganzies  gras  ( Marloth  9720 , PRE),  Reveldsgras 
( Hanekom  2124 , PRE).  It  is  called  gansgras  as 
it  is  one  of  the  first  plants  turning  green  after  the 
rain  and  is  then  utilised  by  geese.  Although 
eaten  by  geese  without  any  ill  effects,  Hanekom 
( Hanekom  2124.  PRE)  mentioned  that  it  caused 
'dikkop'  in  sheep.

APPENDIX 

PLAN  OF  FLORA  OF  SOUTHERN  AFRICA 


Cryptogam  volumes  will  in  future  not  be  numbered,  but  will  be  known  by  the  name  of  the  group  they  cover.  The  number 
assigned  to  the  volume  on  Charophyta  therefore  becomes  redundant.  Occasional  contributions  to  the  Flora  are  published  in 
Bothalia  under  the  title  FSA  contributions. 

Exotic  families  are  marked  with  an  asterisk. 

Published  volumes  and  parts  are  shown  in  bold.
