Typhonium Schott is a genus of about 40 species of East Asian and Australian geophytic, mostly saproentomophilous aroids, the largest genus of the eastern-hemispheric tribe Areae. Typhonium has been revised recently for Australia (Hay 1993) and in toto (Sriboonma 1994), with the subsequent addition of three new species in Australia (Hay 1996; Hay & Taylor 1997). Several further new species are also coming to light in Indochina (Dzu & Croat 1997; Hetterscheid, pers. comm.). Here we describe another new Australian species, bringing the total for Australia to 17, of which all but two are endemic. A key to Australian Typhonium, including this new species, will appear in the forthcoming treatment for “Flora of Australia” (Hay, in prep.).
Stypandra jamesii (Phormiaceae), a new Western Australian species endemic to granite outcrops
The new species of triggerplant (Stylidiaceae) described here is endemic to the Northern Territory. It belongs in Stylidium subgenus Andersonia (R. Br.) Mildbr., which is characterized by having a linear hypanthium, the walls of the mature capsule recurved, the septum erect and persistent, and numerous seeds. This subgenus occurs in regions of tropical northern Australia and extends into south-east Asia (Mildbraed 1908).

Stylidium chiddarcoopingense (Stylidiaceae), a new species from south-west Western Australia
LOWRIE, A., COATES, D.J. AND KENNEALLY, K.F., Nuytsia13 (1): 255–257 (1999)
Stylidium chiddarcoopingense (Stylidiaceae) is a new species of triggerplant endemic to south-west Western Australia. It is a member of the Stylidium caricifolium complex, in which seven species are now recognized. The other six species were described and illustrated in Lowrie et al. (1998). All members of the Stylidium caricifolium complex belong in subgenus Tolypangium Endl., section Squamosae Benth. (Mildbraed 1908).
A new record for the fern flora of south-western Australia: a single plant of Histiopteris incisa from Mt Lindesay
A single large (rhizome length 0.4 m, leaf length 0.5 m) individual of the cosmopolitan fern Histiopteris incisa (Thunb.) J. Sm. (Dennstaedtiaceae) was located on the lower south-western slopes (altitude 110 m) of Mt Lindesay on 3 January 1999. The plant was found growing in a partially shaded, horizontal crevice of a large granite boulder 1.5 m from the ground and 100 metres up a steep slope to the east of the Denmark River. The general area included substantial areas of outcropping in otherwise woodland/forest habitat. This is the first record of this species from south-western Australia, and increases the pteridophyte flora (ferns and fern allies) of the Jarrah Forest Bioregion to 30.
