Setaria
SetariaBeauv. is a verypolymorphic genusnot clearly distinctfrom thosewherethe
rhachis ofthebranches terminatesin a deadend or single bristle. SomeAmerican
species havebeenincludedinSetariasection PaurochaetiumPilg. (Pilger, 1940)or
subgenus PaurochaetiumRominger (1962) whilethec. 22 Australianspecies have
beenplaced in Paspalidium Stapf. They obviously belong in asingle supraspecific
taxon best placed in Setaria, as was previously suggested by me (1980) and also
pointed out by Webster (1987: 203).
Led by thesameconvictionMorat(1978) placed S.jaffreiinSetaria, although the
terminalbristle is minuteandsometimes even absent; thestructure of the inflores-
cence is reminiscentofthatfoundinmanyAustralianspecies ofPaspalidium.
In 'true' Paspalidium theprimary branchesalternateon oneoronopposite sides
ofthe commonaxis, butinlooserand denser inflorescences this becomesobscure
andintermediary formsarepresent. AsPaspalidium cannot be delimitedsatisfacto-
rily,itis herereduced toSetaria.
For convenience'ssake akey andanenumerationofthespecies with distribution,
habitat,and somenotes are given. As several species have anextensive synonymy,
thenomenclatureisreduced tothebasionym andanoccasionalsynonymreferredto
inthenotes.

Burkill [Diet. Econ.Prod. Mai.Pen.(1935) 2034] reports theoccurrence of two
races in Malaya withoutfurther specification. A collection(Kafrawi MS 1029,L)

Distribution- Pan(sub)tropical, widespread inMalesia.
Habitat- Roadsides, waste and burned areas, fields, openforest, sandy beaches,
locally common, andthenconspicuous byits glaucous foliage andgolden topurplish
reddishinflorescences, 0-1650(-2800) m altitude.
Notes- A very polymorphic species withanintricate nomenclature, atpresent
generally known in SoutheastAsiaas S.pallide-fusca, butunfortunatelytobe called
S. parviflora.
Itmaywellbeconspecific withS.pumila (Poir.)Roem. &Schult. (Clayton, 1979)
for thetwo are extremely similar. To retainsomeorderin this polymorphic group,
though, it seems convenienttoregard S.pumila as distinctbecauseofthe size(2.8-
3.5mm long) and shape (relatively broad) ofthespikelets. Ithasbeen saidthatits
leavesaretwistedwhilestraight inS.parviflora,butthisis difficultto seewhen dry,
andIamnot sure itholdsuniversally true.
Even so,S.pumila remainsa very variablespecies withanextensive nomencla-
ture. In olderliteratureitis usually calledS. glauca (L.) Beauv., but itsbasionym,
Panicumglaucum L., is nowconsidered tobebest applied to pearlmillet,Pennise-
tum glaucum (L.)R.Br.
Simon(1984) regarded ‘Setariapallide-fusca’ as asubspecies ofS. pumila be-
cause ofthedifferenceinthelength ofthespikelets. InMalesiathese are generally
1.9-2.4 mm long, but especially in the Philippines, New Guinea, and Australia
there are plants with up to3.2mm long spikelets, which otherwisehavethenarrow
aspect ofS.parviflora andhavethereforebeenincludedhereinthelatter.Ifaccepted
as asubspecies, theepithet'subtesselata’ haspriority.
InNewGuineamanyspecimens with largespikelets have arelativelylonger up-
per glume, whichhave been distinguished as S. montana Reeder. They apparently
occur togetherwiththe 'normal' form,aswas pointed outby Reederforaparatype,
Brass 11814, ‘montana’ in A, ‘pallide-fusca’ in US (and L) andis also shownby
Vink 16314, ‘parviflora’, and 16314-A, ‘montana’ (L). Setariamontanadoesseem
to have awider altitudinalrange, butoccurs atsea-level, too. Evenlonger glumes
has the form describedas S. surgens, the lower becoming acuminate, up to 0.62
timesas long as thespikelet, theupperup to0.92 as long as thespikelet. Itis amat-
ter oftaste, however, where toplace intermediateforms, andthe taxa are included
here.
Setariasurgens leadstotheAustralianS. apiculata (Scribn. & Merr.) K.Schum.,
which according toWebster(1987: 204) differsby (only statistically) longerspike-
letsanda differentdistribution.

Setariaparviflorais bysome dividedintoanannualandaperennialtaxon, S.pal-
lide-fusca andS.parviflora s.s„respectively. Theperennial one wouldbetheonly
oneoriginally presentintheNewWorldandintroducedelsewhere. Itis certainthat
perennials occur in Malesia, viz. the presenceofextravaginal basal branching and
cataphylls, but these mightwell representdifferentstages in development as was
by Stapf forS. surgens. Moreover,annualsandperennials are sometimes
difficult to distinguish in Malesia. Naturally,because bylack of seasons such a dis-
tinctionis impossible, artificially, becauseoftenbasalparts havenot been collected.
There seemstobe no other differencebetweenthe annualsand perennials than the
lifeformandthetwo shouldnotbeseparated. If, with anutmostdegree ofimagina-
tion, wekeep themapart,a great dealofspecimens cannotbeidentified.

Setariasphacelata is a very polymorphic species. Clayton (1979: 503) has divided
itinto5 varietieswhichintergrade completely, but "thosethatwishtoindicatetheap-
proximate position of theirplants withinitmayhaveameansofdoing so."
