CATE Araceae, 17 Dec 2011.

Long confused in herbaria and literature with Rhaphidophora australasica but readily distinguished by flowering on free lateral shoots and by the stipitate spadix. Further, in R. petrieana the petiolar sheaths fall more-or-less intact and do not degrade into semi-persistent fibres as they do in R. australasica.
Lowland to lower montane rain forest
General Description
Medium to large, moderately robust, semi-leptocaul homeophyllous liane to 20 m; seedling and pre-adult plants not observed; LEAVES: adult shoot architecture comprised of greatly elongated, clinging, physiognomically unbranched, sparsely leafy, non-flowering stems and long, moderately elaborated, free, sympodial, densely leafy, flowering stems; stems smooth, climbing and free stems terete in cross-section, green, later mid-brown, without prophyll, cataphyll and petiolar sheath fibre, internodes to 2.5-5 x 0.5-1 cm on clinging shoots, usually less stout on free shoots, separated by well defined, slightly oblique, corky leaf scars, older stems subwoody; flagellate foraging stems absent; clasping roots sparse, arising from the nodes of clinging stems, minutely pubescent; feeding roots not observed; leaves spiro-distichous on clinging shoots, disticho-secund on free shoots; cataphylls and prophylls membranous, very quickly drying and falling; petiole grooved adaxially, 4.5-8 x 0.15-0.3 cm, smooth, apical and basal genicula weakly defined; petiolar sheath very prominent, extending to just below apical geniculum, swiftly drying and eventually falling more-or-less entire leaving a conspicuous scar; lamina entire, narrowly ovate to lanceolate, somewhat falcate, slightly oblique, 4.5-22.5 x 1-4.5 cm, thinly coriaceous, base acute, apex acuminate, with a tiny tubule; midrib raised abaxially, slightly sunken adaxially; primary venation pinnate, slightly raised abaxially and adaxially; interprimaries parallel to primaries and barely less prominent, very slightly raised abaxially and adaxially; secondary venation ± obscure in fresh material, visible as a faint reticulum in dried specimens; INFLORESCENCE solitary, subtended by a partially developed foliage leaf and a membranous cataphyll; peduncle compressed-terete, 3-10 x 0.15-0.8 cm; spathe canoe-shaped, stoutly short- to rather long-beaked, 6-8 x 1-3 cm (8 cm wide flattened out), thickly stiff-fleshy, creamy yellow, caducous at female anthesis; spadix bluntly tapering-cylindric, stipitate, inserted ± level on stipe, 3-6 x 1-2.5 cm; stipe terete, c. 1 x 0.6 cm; stylar region mostly rounded-hexagonal, c. 2 x 1.8-2 mm, conical; stigma punctiform and prominently raised, c. 0.25-0.3 mm diam.; anthers exserted at male anthesis; INFRUCTESCENCE not observed.
