Notes: Distribution: Mexico (Veracruz)

General Description

Habit: Cepitose, new lateral shoots emerging from tops of old dried persistent basal sheaths, forming fairly dense clumps to 3-4 m across, erect, leaning with age, to 4-5 m tall. Stems: 2-2.5 cm diam., green, ringed, often covered with old leaf bases, internodes to 15 cm long. Leaves: 5-7, erect-spreading, pinnate; sheath to 40-50 cm long, tightly clasping, obliquely open apically and there splitting deeply opposite petiole with age, rough-brown-margined, below this whitish and longitudinally striate-nerved, old sheaths persistent, drying brown, hard, durable, ± woody; petiole to 20-35 cm long, lime-green and grooved especially near base above, rounded and pale below; rachis to 0.8-1 m long, sharply angled and lime-green above, rounded below with a green or yellowish band extending onto sheath, attenuate apically; pinnae 20-26 on each side of rachis, lower and middle ones longest, these to 40 x 1.8 cm, becoming progressively shorter.toward apex of rachis, regularly arranged, opposite to subopposite, flat off rachis, elongate-lanceolate, ± straight, only slightly falcate, long-acuminate, slightly contracted basally, ± thick, durable, a prominent pale midrib sharply angled above and 2 much less prominent primary nerves on each side of this, secondaries and tertiaries faint and inconspicuous, midrib prominent below, apical pair of pinnae slightly wider. Inflorescences: infrafoliar, emerging from tops of dried persistent sheaths, erect. Staminate with peduncle to 30 cm long, 1.5 cm wide at base, erect-spreading, pale.green where exposed; bracts 5-6, tubular, obliquely open apically and there bifid except largest which is long-acuminate and greatly exceeds peduncle and often conceals 1 or 2 smaller ones, longitudinally striate-nerved, brown in flower; rachis 20 cm long, light green; rachillae 40-45, these to 25 cm long, 1.75-2 mm diam., spreading-drooping, light green. Pistillate with peduncle to 50 cm long, 1.5 cm wide at base, erect, pale or greenish in flower where exposed, reddish orange in fruit; bracts 6, similar to those of staminate inflorescence, brown and persistent in fruit; rachis to 22 cm long, green-yellow in flower, reddish orange in fruit; rachillae 40, lower ones longest, these to 22 cm long, apical ones to 10 cm long, spreading slightly, ± stiff, yellow-green in flower, reddish orange in fruit. Flowers: Staminate in moderately dense spirals, 3-3.5 mm distant, 3-3.5 x 3-4 mm, subglobose, bright yellow, strongly aromatic, slightly sunken in elliptic depressions; calyx 1 x 2 mm, shallowly lobed, membranous, light green, sepals connate nearly to apex, broadly rounded apically; petals 3.5 x 3 mm, valvate, connate apically and basally and adnate apically to pistillode and corolla opening by lateral slits, perhaps petals later apically spreading slightly but remaining inwardly curved, broadly acute, margins ± thickened; stamens 2.5 mm tall, filaments 1-1.5 mm long, very pale green, nearly clear-colored, anthers I mm long, yellow changing to white; pistillode 2.75 mm tall, columnar, light green, darkened and narrowed apically. Pistillate in rather remote spirals, 8 mm distant, 3 x 3 mm, globose, greenish yellow, slightly sunken in elliptic depressions; calyx 1-1.5 x 3 mm, prominently lobed, very light green or nearly yellow, sepals connate and or lightly imbricate briefly basally, broadly rounded apically; petals 2.5-2.75 x 3 mm, tightly imbricate nearly to apex, acute; pistil 3 x 3 mm, globose, light green, stigma lobes sessile, distinct but low, rounded. Fruits: 7-8 mm diam., oblong-globose, black
