Anthurium martae Croat & Castano Rubiano

Terrestrial to hemiepiphytic, sometimes terrestrial in juvenile stage, usually scandent and climbing to 4-6 m ; internodes 2-15 cm long, 1-3.5 cm diam., dark green, speckled and weakly glossy becoming gray-brown; cataphylls 10-27 cm long, thick but soon turning thin, persisting brownish and semi-intact at upper nodes, sometimes scarcely fibrous but usually persisting as a loose network of pale fibers closely appressed to the stem, eventually deciduous; petioles terete, 58-83(-200) cm long (averaging 69.8 cm), 5-9 mm diam., dark green, matte, sometimes tinged reddish, very weakly sulcate and rarely weakly striate adaxially, flexible; blades ovate-sagittate with basal lobes often overlapping, broadest slightly above the petiole attachment, (33-)44-76(-120) cm long, (20-)24-48 cm wide (averaging 63 x 39 cm), 1.5-2.1 times longer than wide, .7-.9 times as long as petioles, subcoriaceous, dark green and matte-subvelvety above, moderately paler and matte below; midrib thicker than broad and slightly paler above, round-raised and paler below; primary lateral veins (6-)10-12(-14) pairs, narrowly raised and paler above, more or less round-raised below, arising usually at an acute angle then spreading at 45-65°, sometimes at up to 80° angle; basal veins (6-)8-10 pairs, the first (1-)2-3 free to the base, the remainder coalesced to varying degrees and regularly branching from the posterior rib; posterior rib naked (1-)3-5(-9) cm along sinus; tertiary veins prominulous in part below; collective veins arising usually from one of the middle or even upper primary lateral veins but often from the 1st pair of basal veins, sometimes from the 2nd pair of basal veins, mostly 4-10 mm from margins, sometimes 2 mm or up to 1.5 cm from margin. INFLORESCENCES erect-spreading; peduncle terete, medium-green, matte, 34-70 cm long, 4-7 mm diam.; spathe linear-lanceolate, 13-30 cm long, 1-3 cm wide, medium green or greenish white, erect then reflexed, brittle; spadix 14-26 cm long 5-8 mm diam., green, greenish yellow eventually turning purplish violet, semiglossy, usually stipitate 4-6 mm, rarely to 2-2.5 cm in flower (more commonly stipitate 1-2 cm long in fruit); pollen white; pistils early weak-emergent. INFRUCTESCENCE with stipe to 2 cm long, fruiting spadix to 50 cm long, 2.5-3 cm diam.; berries green.
