Anthurium sytsmae Croat

Rupicolous; 35-50 cm tall; stems ca. 10 cm long; roots moderately few, descending, ca. 3 mm diam.; cataphylls 6-9 cm long, narrowly pointed at apex, thin, soon weathering to slender, pale brown fibers and persisting loosely at uppermost nodes, eventually falling. LEAVES erect to spreading; petioles 13-18 cm x 2-3 mm, narrowly sulcate; geniculum 1.3-1.5 cm long; blades subcoriaceous, oblong-oblanceolate, 19-25 x 3-4.5 cm, gradually acuminate at apex (the acumen 1-2 cm long, apiculate ca. 1 mm), narrowly acute at base, epunctate below, drying yellowish brown, sparsely and obscurely glandular-punctate above, drying grayish brown; midrib raised below, weakly raised above; primary lateral veins 5-7 pairs per side, prominently ascending, departing midrib at 15-30° angle, drying scarcely more prominent than the interprimary veins; reticulate veins drying prominulous on upper surface, prominent on lower surface; collective vein arising from one of the primary lateral veins in the middle to lower third of the blade. INFLORESCENCE erect, usually longer than the petioles; peduncles 13-16 cm long; spathe oblong-lanceolate, 2.7-4.7 cm X 5-10 mm, green, at first erect, becoming prominently reflexed, narrowly acuminate at apex (the acumen 1-6 mm long, inrolled), inserted at ca. 45° angle; spadix stipitate 2-3 mm, greenish brown (probably at anthesis), narrowly oblong, scarcely or not at all tapered, 7.4-9.5 cm x 3 mm (dried), bluntly rounded at apex. Flowers rhombic, 2.2-2.5 x 1.9-2.2 mm, the sides gradually sigmoid; 3 flowers visible in the principal spiral, 5-6 flowers visible in the alternate spiral; tepals drying glossy, lateral tepals 1.3-1.4 mm wide, inner margins convex, thin; pistils not at all emergent, green; stigma slit-like, 0.3 mm long, the space between the tepals 0.3-0.4 mm wide; staminal emergence not studied, stamens apparently retracting (at least upon drying); anthers 0.3 mm long; thecae oblong-ovoid, slightly divaricate. INFRUCTESCENCE spreading; spathe persistent; berries green, obovoid, round at apex, 6.5-9 X 4.5-5.5 mm, periderm thick, lacking obvious raphide cells; seeds 2, 4.5-5 x 2-2.8 mm, somewhat flattened, enveloped in a gelatinous substance.
