Araceae
Anthurium llewellynii Croat
SUMMARY
Usually terrestrial, rarely epiphytic; stem creeping, to 20 cm long; internodes short, 2.5-4 cm diam.; roots numerous, dense, descending, whitish velutinous, 4-5 mm diam.; cataphylls subcoriaceous lanceolate, 3-7 cm long, acute to acuminate at apex, drying brown (B & K yellow 3/7), persisting as a reticulum of fibers. LEAVES erect-spreading to spreading; petioles (5)12-40 cm long, 3-8 mm diam., erect, sharply D-shaped, flattened to slightly convex adaxially, rarely with a medial rib, the margins sharply raised, rounded abaxially; geniculum paler than petiole, becoming calloused with transverse fissures, conspicuously thicker than petiole, 0.5-2 cm long, sometimes extending beyond leaf base up to ? its length; sheath 2-6 cm long; blades subcoriaceous, oblanceolate to narrowly oblanceolate or elliptic, acute to acuminate at apex, narrowing toward the base, ending abruptly, obtuse to rounded or shallowly cordate at base, (29)50-110 cm long, (5)7- 15(20) cm wide, broadest at or above the middle, the margins moderately to broadly undulate; upper surface glossy to semiglossy occasionally matte, dark to medium green (B & K green 3/7.5), lower surface matte to semiglossy, considerably paler; midrib pale-speckled, conspicuously to scarcely paler than surface broadly rounded-raised at base, becoming acutely angled toward the apex above, broadly rounded-raised to bluntly angled and slightly paler than surface below; primary lateral veins 4-12 per side, departing midrib at 35-90° angle (rarely retrorse to 110°), arcuate-ascending to the margin, convexly raised and paler than surface above, less prominently raised and darker than surface below; interprimary veins almost as conspicuous as primary lateral veins; tertiary veins obscure; collective vein arising from near the base or in the upper third of the blade, weakly raised above and below, 3-19 mm from margin. INFLORESCENCES erect to spreading; peduncle 23.5-75 cm long, 3-5 mm diam., equalling to 5 x as long as petiole, green to brownish green, pale-speckled, terete to subterete; spathe spreading to reflexed, coriaceous to subcoriaceous, green, sometimes tinged with red at margins, lanceolate to ovate-lanceolate, 5-9 cm long, 1-2.5 cm wide, broadest near the base, inserted at 45-60° angle on peduncle, abruptly acuminate to acute at apex (the acumen inrolled), acute at base; spadix reddish olive-green, sessile, cylindroid, slightly tapered, erect or slightly curved, 3.6-9 cm long, 5 mm diam. midway, 3-4 mm diam. near apex; flowers rhombic to 4-lobed strongly scented like rotting fruit, 1.5-3 mm long, 2-2.4 mm wide, the sides jaggedly sigmoid to straight; 4-8 flowers visible in principal spiral, 5-7 in alternate spiral; tepals matte, sparsely white-punctate, densely papillate; lateral tepals 0.6-0.8 mm wide, the inner margins straight to broadly convex, the outer margins 2-4-sided; pistils weakly raised, olive-green to maroon; stigma linear-oblong, caviform, 5 mm long; stamens emerging in a scattered pattern from the base, the laterals preceding the alternates by up to 17 spirals, the 3rd stamen preceding the 4th by 13 spirals, arranged in a circle around the pistil; anthers pinkish to yellow tinged with pink, 0.3-0.6 mm long, 0.5-0.9 mm wide; thecae oblong-ovoid, slightly divaricate; pollen yellow fading to white. INFRUCTESCENCE spreading-pendent; spadix 11-18 cm long, 1-1.3 cm diam.; berries dark purple (B & K red-purple 2/2.5), globose-obovoid to subglobose, truncate at apex, 5 mm long, 3-5 mm diam.; pericarp moderately thickened; mesocarp gelatinous, with raphide cells; seeds 1-2 per berry, brownish purple, oblong-ellipsoid, 4-5 mm long, 2.1-2.5 mm diam., 1.5-2 mm thick, with a gelatinous appendage at both ends.
