    Conservation

    Conservation for Anthurium pulcachense must be considered as Data Deficient (DD) according to IUCN Red List criteria (IUCN, 2001) because the species is known only from a single introduction from the type locality. The species therefore remains in need of further investigation against future conservation efforts.

    Ecology

    Anthurium pulcachense is endemic to Peru, known only from the Department of San Martin, Province of Mariscal Caiceres at 630 to 950 m elevation, near Pulcache (hence the name "pulcachense") in Premontane wet forest (P-wf).

INFLORESCENCE erect; peduncle 25-40.7 x 0.4-0.8 cm, ca. as long as petiole, quadrangular-winged in cross section (one or more sides with a medial rib), dark greenish brown and glistening; spathe reflexed to erect-spreading, lance olate, green, 4-18 x 1-4 cm, subcoriaceous, inserted on peduncle at ca. 25°-30°; peduncle 2.2-6.3x longer than spathe; stipe 0.4-2.3 cm in front, 0.2-0.4 cm in back; spadix erect, held at ca. 10°-15°, 3-17.4 cm, 2-3 mm diam. at apex, 3-7 mm diam. at base, dark green, matte, drying brown. Flowers 6 to 7 visible in principal spiral, 3 to 5 flowers visible in alternate spiral, 2.6-2.8 x 1.6-2.6 mm; tepals matte; lateral tepals 1.6-2.6 mm, subtriangular, inner mar gins rounded, outer margins 2-sided; stamens closely clustered and held at surface of tepals, usually not contiguous, stamens held at surface of tepals; lateral stamens preceeding alternates by 7 spirals; anterior stamens preceding posterior by 4 spirals; anthers ca. 1.5 x 1 mm, drying ca. 0.24 x 0.4 mm; thecae ovoid elliptic, moderately divaricate; pistils weakly exserted above tepals, purplish.
