    Distribution
    Thailand (south peninsular). In Malesia: Peninsular Malaysia.
    Habitat
    Shady to open areas in wet, occasionally swampy, primary forest, often on steep slopes.
    General Description
    Slender, heterophyllous, root-climbing liane to 7 m. Stem?; eocaul not observed; seedling shingle-leaved. LEAVES bright to mid-green adaxially, slightly paler abaxially, stiffly chartaceous, drying dull green with the midrib pale yellow and prominently raised; petiole 4–12 × 0.2–0.25 cm, slender, sheath extending to geniculum, clasping basally on juvenile and mature sterile shoots, prominent and sheathing to 4/5 of its length on fertile shoots; blade 5–25 × 2.3–9 cm, ovate to elliptic or lanceolate, base acute to rounded, apex attenuate-mucronate, acute or attenuate, minutely apiculate; primary lateral veins arising at 45–65°, with 3 intramarginal veins per side, the lowermost arising from the base, subsequent veins arising from the lower part of the midrib, outer intramarginal vein remaining very close and parallel to margin, the second and third progressively nearer to the midrib, all reaching the leaf tip. INFLORESCENCE solitary, usually subtended by cataphylls on condensed short shoots in the axils of distal leaves, occasionally from such shoots arising (persisting?) on leafless older stems, rarely terminal on leafy shoots, by reflexing of the peduncle held inverted beneath the shoot; peduncle 2–5 × 0.15–0.25 cm, stout, reflexed c. 90° at the base, yellow to orange-brown. Spathe 4–10 × 2.5–6 cm, ovate, deeply cucullate, base slightly decurrent on the peduncle, apex acute, deep purple inside and out, softly leathery and rather prominently net-veined. Spadix sessile, 2.5–7 × 0.3–0.8 cm, cylindrical, deep purple-brown. Flowers c. 1 mm diam., with 6 free tepals and 6 stamens. INFRUCTESCENCE with 4–10 berries; fruits c. 2–4 × 2.5–9 mm, oblong-ellipsoid; seeds not observed.
    Diagnostic
    Unique due to its deeply cucullate, softly leathery, deep purple spathe, P. kingii is restricted to southern Peninsular Thailand and a few localities in Peninsular Malaysia where it occurs in wet forest. Fertile specimens are instantly recognizable but sterile material could be confused with vegetatively similar P. lorispathus (to which P. kingii is allopatric), and P. curtisii. The last is known from one locality in Peninsular Thailand but is widespread and locally common in Peninsular Malaysia.
