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 en Eriocephalus L. ( Asteraceae ) in snidelike Afrika, unpublished Ph.D. thesis;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.

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-

spicuous because its small capitula lack a con-
spicuous long, dense indumentum at fruiting
and are hardly visible among other plants.

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.
Common name: kapokbos.

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.

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.

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.

ASTERACEAE: Eriocephalus
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-
den among subtending leaves. E. punctulatus
has mostly 7-10 disc florets while E. tenuifolius
has mostly 13-22.

the Free State, Lesotho and the Northern,
Western and Eastern Cape. Most of the distribu-
tion area receives summer rain. Map 5.

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.

truncate, rarely with sweeping hairs. Receptacle
after anthesis with dense, brown, long-pilose
indumentum between involucral bracts and
connate marginal paleae. Chromosome number.

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.
Common name: kapokbos.

plains. It forms part of the flora of the sandstone
hills and mountains extending from the Namib-
Naukluft Park southwards to the Orange River.

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
paniculate; peduncles (3.0— )6.0— 8.5(— 1 2.0) mm
long, permanently felty sericeous. Ray florets 3
or 4(5), 3. 2-4.0 mm long; lamina white, broad-
ly cuneate, 4-5 mm long. Disc florets (12-)
1 6— 1 8(— 24). Flowering time : correlated with
rainy season, from July to September, but flow-
ers can be found throughout the year as plants
receive moisture from sea mist. Figure 3.
This variety is mostly restricted to the coast
of the Cape Peninsula, but also occurs from
26
ASTERACEAE: Eriocephalus
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.
It is one of the few species of Eriocephalus
that are highly palatable. E. africanus, in con-
trast, is not or hardly browsed. Common name:
kapokbos.

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.

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).

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.

After E. africanus, E. racemosus is the old-
est known species of Eriocephalus. Although it
is relatively easy to distinguish E. racemosus
from related taxa, a few herbarium specimens
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.

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-
kapok (Bredasdorp area) and kapkappie.

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.

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.
44
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:
Leaves glabrescent, shiny, bright green . . .
26a. subsp. ericoides
Leaves permanently long-felty, dull green
26b. subsp. griquensis
26a. subsp. ericoides.
Older leaves glabrescent, shiny, (0.75-)
1.0-3. 0(— 5.0) x 0.3-0.4 mm. Peduncles 1-5 mm
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
Map 14. — • Eriocephalus ericoides subsp. ericoides; ■ E.
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
ASTERACEAE: Eriocephalus

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:
gewone kapokbossie , renosterveldkapok , roos-
maryn , rosemary (Smith 1966); gladdekapok-

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

ple young shoots with a diameter of less than 1
mm. The leaves of E. microphyllus are
(1.2-)1.5-4.0(-7.0) x 0.6-0. 8 mm on rigid
branches. Internodes of young shoots of E.
microcepholus are 4. 0-8. 5 mm long as opposed
to the 3-5 mm of those of E. microphyllus. Side
branches are mostly opposite, forming an angle
of 70-90° with the main axis in E. micro -
cephalus, but less than 70° in E. microphyllus.
E. microcephalus is fairly rare and restricted to
a few high mountains, whereas E. microphyllus
is common in Namaqualand.
E. microcephalus did not transplant well and
even cuttings did not survive, but mature E.
microphyllus plants transplanted well and cut-
tings rooted successfully. Common name:

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.

Map 19. — • Eriocephalus namaquensis; ■ E. merxmuel-

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.
Common name: kapokbos.

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

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.

pila Burch., without mentioning any species,

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.

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.

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.

ASTERACEAE: Lasiospermum
Much-branched, mat-forming, perennial herbs,
rarely erect, rather ascending, 100-300 mm tall,
up to 400 mm in diameter. Older stems decum-
bent, glabrescent, sometimes rooting at nodes;
young growing points densely long-pilose.
Leaves initially rosulate; petiole broadened
basally, semi-amplexicaul, relatively short with
serrate-dentate margins; lamina pinnatisect to
bipinnatisect, 40-75 x 5-15 mm. initially deli-
cately long-pilose, glabrescent; leaves on flow-
ering shoots basally pinnatisect with decreasing
number and size of lobes transending to pedun-
cle; lobes oblanceolate, mucronate with hard,
white mucro. Capitula homogamous discoid,
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.
