Abstract:Selaginella braunii Baker and S.siamensis Hieron are reported from Malaysia for the first time.The
specimens are preserved in herbarium of Singapore Botanic Gardens.
Key words:Selaginella braunii Baker;S.siamensis Hieron;Malaysia
  The Selaginelaceae of Malaysia was firstly studied
by von Alderwwerelt van Rosenburgh in 1915in his
monograph of Malayan Fern Alies,four years later in
1919,Ridley made an account of 37species of Selagi-
nellafrom the Malay Peninsula.Alston(1934)re-
duced this number to 25and by the time of his taxo-
nomic account of Sumatran species in 1937,the Penin-
sular Malaysian Selaginella numbered 26species.
Wong(1983,2010)made detailed studies of the Selag-
inelaceae from Malaysia and published the treatment
in its Flora,29species were recognized,of which nine
are endemic.
Recently the senior author was supported by the
Gadern’s scholarship to study by the rich fern colec-
tions in Singapore Herbarium (SING),the Selaginel-
laceae from Malaysia and adjacent regions were
re-identified,as a result,it was found that the folow-
ing two additional species occurring in Malaysia had
been overlooked in previous studies.

es.Leaves decussately arranged except on main stem,
dimorphous,rather fleshy,surface glabrous,obviously
wrinkled,not white-margined,leaves on unbranched
main stems wel spaced(up to 20mm apart),about
the same size as those on branches,monomorphous,

keeled,base peltate(on basal of stem and creeping rhi-
zome or stolons),margin lacerate or lacerate-ciliate.
Axilary leaves on branches symmetrical,eliptic or
narrowly eliptic or oblong,(1.8-3.2)mm×(0.6
-1.4)mm,margin subentire or denticulate or cilio-
late,base exauriculate.Lateral leaves asymmetrical,
ovate-triangular or oblong-falcate,slightly ascending,

leaves on branches narrowly eliptic or falcate,(1.6-
2.8)mm×(0.4-1.2)mm,contiguous or imbricate,
not carinate,apex acuminate,base obliquely decurrent,
margins subentire,slightly involute(when dry).Stro-
bili(5.0-6.0)mm×(1.4-2.3)mm,sporo phyls u-
niform,broadly-ovate or suboribicular,margin denticu-
late,not white-margined,apex acute.

hor,Pengerang,3-VII-1936,Z.Teruya 2840(SING);
