Anthurium paraguayense var. paraguayense

Terrestrial or epiphytic; stem to 40 cm long, (1)5-6 cm diam.; roots numerous, dense, descending or ascending, green or tan, smooth to pubescent, blunt, longitudinally fissured when dried, 3-10 cm long, 2-5 mm diam.; cataphylls membranous to subcoriaceous, 3-9.5 cm long, acute and sharply 1-ribbed at apex (apiculate to 1 mm), pale green, drying dark brown to tan (B & K yellow 6/5), persisting as a reticulum of fibers at base. LEAVES erect to spreading; petioles 3-28.5 cm long, 6-10 mm diam., D-shaped to sometimes nearly quadrangular, shallowly sulcate with a medial rib adaxially, the margins acutely raised, bluntly to sharply 1-3-ribbed abaxially, the surface green sometimes pale-speckled; geniculum thicker and paler than petiole, 0.7-2.5 cm long; sheath 0.9-2.5 cm long; blades subcoriaceous, oblanceolate to oblong-oblanceolate, long-acuminate at apex (the acumen inrolled to flat), acute to obtuse to rounded or truncate at base, 22-100 cm long, 5-19.5 cm wide, broadest above the middle, the margins prominently undulate; both surfaces semiglossy to matte, dark to medium green above, paler or concolorous below; both surfaces drying usually greenish; midrib broadly raised at base with an acute medial rib, diminishing and becoming sunken toward the apex above, slightly raised when dried, convexly raised at base, becoming acute and then narrowly raised toward the apex above, slightly raised when dried; primary lateral veins 4-10 per side, departing midrib at (25)30-70° angle, arcuate-ascending to the margin or loop-connecting to the primary lateral vein above it, raised above near the midrib, weakly sunken at the margin, raised below; interprimary veins obscure above, visible below; collective vein arising from near the apex, weakly sunken above, bluntly raised below, prominulous when dried, 5-9 mm from margin. INFLORESCENCES erect or spreading, shorter than leaves; peduncle 14-65 cm long, 8-9 mm diam., ca. 2-6 x as long as petiole, dark green, terete to subterete; spathe spreading to reflexed with the margins rolled under, coriaceous, dark green tinged with purple (B & K yellow-green 4/7.5), lanceolate to ovate-lanceolate, (2)6-15 cm long, (0.7)1.7-3 cm wide, broadest in the lower third, inserted at 40-50° angle on peduncle, acute to acuminate at apex (the acumen inrolled), acute to decurrent at base, minutely verruculose on inner surface; spadix green tinged with purple or graybrown (B & K yellow 5/7.5), tapered, (2.4)5-15 cm long, 4-15 mm diam. near base, ca. 3-8 mm diam. near apex; flowers 4-lobed to rhombic, (1.7)2.5-4 mm long, (2.2)2-4 mm wide, the sides jaggedly sigmoid; 5-8 flowers visible in principal spiral, 7-10 in alternate spiral; tepals matte, sometimes appearing punctate and papillate; lateral tepals 0.9-1.5 mm wide, the inner margins convex or straight, the outer margins smoothly 3-4-sided; pistils not emergent or scarcely emergent, green tinged with purple; stigma ellipsoid to slit-like, 0.2- 0.5 mm long; stamens emerging in a regular sequence, emerging shortly above the tepals, the laterals preceding the alternates by 10-12(21) spirals, the 3rd stamen preceding the 4th by 3-4 spirals; filaments translucent, with raphides, 1-1.5 mm long; anthers yellowish to red-purple (B & K red-purple 7/5), 0.5-0.7 mm long, 0.8-0.9 mm wide, inclined over and obscuring the pistil; thecae oblong-obovoid to oblong-ellipsoid, slightly, or not at all divaricate; pollen pale yellow to cream, scented-like grass. INFRUCTESCENCE spreading-pendent; spathe persisting; spadix 17.5-20 cm long, to 3.5 cm diam.; berries reddish to maroon (B & K redpurple 2/7.5), obovoid, rounded at apex, 5-10 mm long, 3-6 mm diam.; pericarp moderately thickened, with raphide cells at base; mesocarp translucent to milky, thick-gelatinous; seeds 2 per berry, white, streaked with reddish or maroon, ovoid, flattened, 5-6.2 mm long, 2.5-3.4 mm diam., 1-2 mm thick, with a gelatinous appendage at both ends.
