Terrestrial; stem to 19 cm long, ca. 1 cm diam.; roots dense, ascending, green to whitish, pubescent to smooth, short, 1–1.5 cm long, 5–6 mm diam.; cataphylls subcoriaceous, linear-lanceolate, 3–10.5 cm long, obtuse to acute or acuminate at apex, drying reddish brown (B & K yellow-red 4/10), persisting more or less intact, splitting at base. Leaves erect-spreading; petioles 4–7 cm long, 5–7 mm diam., erect-spreading, subtriangular, convexly raised to obtusely ribbed, sometimes broadly sulcate adaxially, the margins sharply raised, somewhat rounded and sharply 1-ribbed abaxially, conspicuously swollen to 14 mm diam. at base; geniculum slightly paler and conspicuously thicker than petiole, 0.5–2 cm long; blades subcoriaceous, oblong-linear, acute, sometimes apiculate at apex, acute to rounded at base, 25–85 cm long, 2.5–6.5 cm wide, broadest at or near the middle, the margins broadly and shallowly undulate; upper surface matte to semiglossy, medium green, lower surface matte, conspicuously paler; midrib above obtusely raised at base, becoming sharply and acutely raised and higher than broad toward the apex, pale-speckled, slightly paler than surface, below acute throughout, paler and more yellowish than surface; primary lateral veins 8–15 per side, departing midrib at 30–60(-70) degree angle, not well distinguished from interprimary veins, slightly arcuate to the margin, weakly sunken to weakly raised in shallow grooves, rather obscure above; interprimary veins almost as conspicuous as primary lateral veins; tertiary veins obscure above, conspicuously darker than surface below, prominulous on both surfaces when dried; collective vein usually arising from near the apex, sometimes from near the base, obscure above, equally as prominent as interprimary veins below, 1–7 mm from margin. Inflorescences erect-spreading to spreading, shorter than or equalling leaves; peduncle 38–57 cm long, 4 mm diam., 7.6–19(38) times as long as petiole, green, terete; spathe spreading to reflexed-spreading, coriaceous, yellow-green, sometimes tinged with purple abaxially (B & K yellow-green 5/7.5), narrowly lanceolate, 7–8.5 cm long, 0.8–1.5 cm wide, broadest near the base, inserted at 45 degree angle on peduncle, acuminate at apex (the acumen inrolled), obtusely rounded at base; spadix glaucous, dull lavender-purple (B & K purple 5/2.5), sessile, slightly tapered, cylindroid, erect, 5–8.2 cm long, 7–9 mm diam. near base, 4–6 mm diam. near apex, broadest at the base; flowers 4-lobed, 2.1–2.6 mm long, (1.5)2.4–3 mm wide, the sides weakly sigmoid; (4)7–9 flowers visible in principal spiral, (3)5–7 in alternate spiral; tepals matte; lateral tepals 0.8–1.4 mm wide, the inner margins weakly concave to slightly rounded, the outer margins usually 2-, sometimes 3–4-sided; pistils emergent, bright green (B & K yellow 5/2.5); stigma ellipsoid, 0.3–0.4 mm long; stamens emerging in a regular sequence from the base, the laterals preceding the alternates by 9 spirals, the 3rd stamen preceding the 4th by 3 spirals, borne at edge of tepals in a circle around the pistil; anthers straw-colored (B & K yellow-red 9/10), 0.6 mm long, 0.8 mm wide; thecae ovoid, slightly or not divaricate; pollen pale yellow] (B & K yellow 9/2.5), sweetly scented at anthesis. Infructescence with persistent spathe; fruits not seen.

Discussion

Anthurium linguifolium is known from only three collections made in coastal Ecuador in Manabi and Guayas provinces, between Bahia de Caraquez and Canoa, near sea level in a very dry tropical forest life zone. This species is characterized by its linearoblong, weakly undulate blades, short petioles, rather elongate stem with short, more or less erect roots throughout its length (above ground) and by its glaucous, dull lavenderpurple spadix.
The closest ally of A. linguifolium is A. barclayanum. The latter differs in greenish (rarely violetpurple) spadix, much larger size, longer petioles and oblanceolate blades. A.barclayanum is sympatric with the present species at at least one locality, but they occur in very different habitats. The first is epiphytic, the second terrestrial in open areas. In addition, the ratio of peduncle to petiole length is much greater in A. linguifolium (7.6--19(38), vs. 3.5--6(9)).
