CATE Araceae, 17 Dec 2011.

General Description
Small to medium-sized, heterophyllous, sometimes homeophyllous, creeping rheophyte, very rarely short liane, to 75 cm; seedling stage a non-skototropic shingling shoot, soon becoming spreading-leafy; pre-adult plant initially with ± appressed shingle-leaves, later with leaves erect or spreading and at this stage plants resembling adult in all but overall size and leaf division ; LEAVES: adult shoots all sympodial, clinging and flowering but main axis comprised of longer modules than axillary axes; stems smooth, mid- to dark green, with very sparse petiolar sheath fibre, internodes 1 - 7 x c.c. 1 cm, separated by variously prominent slightly oblique leaf scars; flagellate foraging stems absent; clasping roots very densely arising from the nodes and internodes of clinging stems, pubescent; feeding roots very strongly adherent, densely scaly; leaves distichous, appressed and shingling to erect or spreading and scattered on pre-adult shoots, tending to become distally clustered on adult shoots; cataphylls and prophylls membranous, soon drying and falling; petiole narrowly canaliculate to carinate, 8-31 x 0.3-1.5 cm, smooth, apical and basal genicula prominent; petiolar sheath prominent, extending to the apical geniculum, variably persistent and mostly degrading into semi-persistent weak fibres; lamina entire in seedling and pre-adult individuals, entire, pinnatipartite or pinnatisect in adult plants, narrowly-lanceolate to oblong-elliptic, slightly oblique, 21-51 x 2-23 cm, sub-coriaceous to slightly fleshy, base decurrent, apex acuminate with a moderately prominent tubule; mid-rib prominently raised abaxially, sunken adaxially; primary venation pinnate, raised abaxially, slightly impressed adaxially; interprimaries sub-parallel to primaries, slightly raised abaxially, ± flush adaxially, often forming a weak reticulum; secondary venation prominently reticulate, slightly raised; tertiary venation a network of broadly spaced tessellate veins arising at c.c. 90º from the mid-rib and crossing the primaries and interprimaries; INFLORESCENCE one to three together, subtended by a prominent cataphyll degrading to fibres before anthesis; peduncle terete, 8-12 x 0.2-0.4 cm; spathe narrowly canoe-shaped, stoutly beaked, 6.5-7 x 1-1.5 cm, stiffly fleshy, greenish to dull white, swiftly falling at anthesis; spadix cylindrical, sessile, inserted perpendicular to peduncle, 4.5-7 x 0.6-1 cm, dull whitish; stylar region rather well developed, mostly rhombohexagonal, c.c. 1-1.5 x 1-1.5 mm, truncate; stigma elliptic, longitudinally orientated, occasionally almost circular, c.c. 0.5 x 0.3 mm, often very prominent especially in dried material; anthers exserted at anthesis; INFRUCTESCENCE 7-9 x 1-2 cm, mid-green when ripe.
Rheophytic on rocky wooded streambanks, on rocks in streams and rivers, in soft mud, sandy beds and bare rock on limestone or granite .in primary to disturbed old secondary lowland to hill and swamp forest
Trichosclereids abundant (many 'hairs' apparent when a mature leaf lamina is torn). Leaf with petiole broadly canaliculate, sheath margins broad, spreading, persistent, extending to apical geniculum; leaf lamina thinly coriaceous, often variegated silvery grey. Ripe fruits with stylar region abscising
Peninsular Malaysia (Johore, Kelantan, Negri Sembilan, Pahang, Penang, Perak, Selangor, Terengganu), Thailand (southern peninsula), Indonesia (Sumatera and throughout , Kalimantan) and throughout Borneo.
