CATE Araceae, 17 Dec 2011.

Superficially similar to Rhaphidophora australasica but readily separated by its flowering on free lateral shoots, by the flat-topped styles and the smaller, narrower, much more coriaceous leaves. In addition, being a montane species, R. kokodensis is separated altitudinally. Confusion with R. pilosa (also flowering on free lateral shoots) is possible, although R. kokodensis has petiole and shoot fibres without the distinctive felted appearance of those of R. pilosa.
Papua New Guinea (Central Prov. - Kokoda and Port Moresby).
General Description
Small, homeophyllous (?) liane to unknown ultimate height; seedling stage and pre-adult plants not observed; LEAVES: adult shoot architecture comprised of elongated, clinging, physiognomically unbranched, leafy, non-flowering stems and long, moderately elaborated, free, sympodial, densely leafy flowering stems; stems terete in cross-section, internodes to 1-4 x 0.5-0.8 cm, separated by slightly oblique, prominent leaf scars; flagellate foraging stems, clasping roots, and feeding roots unknown; leaves spiro-distichous on free shoots; cataphylls and prophylls chartaceous but very soon degrading into long tough fibres; petiole deeply canaliculate, 5-16 x 0.2-0.25 cm, smooth, apical geniculum quite well defined, basal geniculum weak; petiolar sheath prominent, chartaceous, extending to apical geniculum, very swiftly degrading to fibres; lamina entire, narrowly lanceolate to narrowly lanceolate-elliptic, occasionally slightly falcate, 13-25 x 1.75-6 cm, stiffly coriaceous, base acute, apex acuminate to long-acuminate with a minute tubule; midrib slightly raised abaxially, slightly sunken adaxially; primary venation densely pinnate, slightly raised abaxially and adaxially; interprimaries parallel to primaries indistinguishable from them; secondary and tertiary venation very faintly reticulate; INFLORESCENCE solitary, subtended by an underdeveloped foliage leaf and much degraded cataphyll fibre; peduncle compressed-terete, 7-12 x 0.2-0.3 cm; spathe narrowly cigar-shaped, long stout-acuminate, (4-)8-9 x c. 1.3 cm, marcescent(?); spadix cylindrical, sessile, 2-6 x 0.8-1 cm; stylar region rhombohexagonal, c. 0.9-1 x 0.8-1.1 mm, truncate; stigma punctiform, very slightly raised, c. 0.4 mm diam.; anthers not exserted at male anthesis; INFRUCTESCENCE cylindrical, c. 11 x 1.3 cm.
Submontane rain forest on dark brown loam.
