Araceae
Anthurium consimile Schott
SUMMARY
Terrestrial and epipetric; stem terete, grayish brown; internodes short, 1.3-35 cm long, 2-35 cm diam.; cataphylls per-sisting intact at upper nodes, 4.4-11.2 cm long, 1-2-ribbed, triangular, dark brown to reddish brown, coriaceous. LEAVES erect to spreading; petioles 33-96 cm long, 0.5-1.2 cm diam., terete to obtusely and narrowly sulcate; medium green, sometimes tinged reddish toward base, semi-glossy, unmarked; sheath 5.6 cm long; geniculum 1.7-2.6 cm long; blades subcoriaceous, semiglossy, moderately bicolorous, 42.8-62.8 cm long, 29.9-42.8 cm wide, wider to middle, widely ovate, acuminate at apex, deeply cordate at base; posterior lobes oblong-rounded, convergent to sometimes overlapping, 5.4-10 cm long, sinus spathulate to hippocrepiform; dark green and semiglossy to matte above, moderately paler to semiglossy below; midrib moderately acute, bluntly acute to acute and slightly paler above, narrowly rounded to acute and paler below; primary lateral veins (6-)8-10 per side, strongly recurvate-ascending, bluntly acute and concolorous on both surfaces, departing midrib at 40-45° angles, tertiary veins in part raised, reticulate veins not visible; basal veins 5-7 pairs, joining the 1st to 3rd basal rib; basal rib 3.1-3.3 cm long, straight to recurved, naked 1.7-1.9 cm; collective veins restricted to apex or above the middle, 1-5 mm from the margin. INFLORESCENCE erect; peduncle 11.5-33 cm long, 0.4-0.6 cm diam., terete, much shorter than the petioles; spathe subcoriaceous, green, persisting on fruiting, erect to spreading, 7.4-17.3 cm long, 1-3.4 cm wide, oblong-lanceolate, acute to brevi-acuminate to apex, subcordate to base; spadix slightly tapered to apex, 10.2-17.5 cm long, 0.5-0.8(-1.2) cm wide near to base, 0.3-0.8 cm wide near to apex, dark purplish; stipe green, 0.7 cm long in front, sessile to 0.2 cm long in back; flowers square, sides straight to slightly sigmoid, ca. 2 X 2 mm; 8 flowers visible in the principal spiral, 6 flowers visible in the alternate spiral; tepals smooth, unmarked (minutely papillate on magnification); lateral tepals 3-sided, 1.3 cm wide, inner margins convex; pistils ca. 2 mm long, oblong; stigmas rounded; stamens ca. 1.5 mm long; anthers 0.7 mm wide, emerging just above the margins of the tepals and remaining in a contiguous cluster, covering the stigmas; thecae slightly divaricate; pollen drying yellow-brown. INFRUCTESCENCE erect; spadix 10.2-23.3 cm long, 1.2 cm wide; berries 0.5 cm, ovate with the upper part protruding. It was necessary to lectotypify the species owing to the fact that Schott did not sufficiently define the collection in his original description. There are two existing collections in the Vienna herbarium (W). These may have been on loan during the Second World War because most of the rest of the Araceae collection was destroyed by war action but these specimens are extant. The lectotype specimen consists of only a leaf blade (without petiole) and an inflorescence with a piece of the peduncle, and the second consists of a smaller leaf and two inflorescences. The second specimen at W was also illustrated by Schott (Jcones #626), but prepared in September 1829, whereas the type (Schott Icones #627) was prepared in July 1829. The type specimen of A. consimile was initially identified as A. humboldtianum Kunth, a species actually known only from Colombia and Venezuela. The locality cited on the label is "Peruvia subandina. Supra terram-illegible-ad Cuchero", it corresponds to San Juan de Cochero, located in the Huanuco Department at the coordinates 9°30"S, 75°51"W. This area is near to other known collecting localities of Poeppig, such as Pompayacu.
