    Habit
    Epilithic. Stem up to 6 cm long, rosulate, erect or procumbent, internodes less than 1 mm long, 2 – 3 cm in diam.; roots dense, spreading or descending, greyish to greenish, smooth, 1 – 3 mm diam.; cataphyll chartaceous, lanceolate, 3 – 5 cm long, attenuate at apex, purplish tinged with brown, persisting with apex more or less intact, but dilacerated as fibres below
    Leaves
    Leaves 6 – 13 per plant, erect to spreading; petioles 3 – 6 × 0.5 – 0.6 mm, “U” shaped, rounded abaxially, canaliculate with obtuse margins adaxially, surface pale speckled, geniculum thicker than the petiole 1.5 – 2 cm long; blade subcoriaceous, linear to linear-lanceolate, apex acute, base acute to cuneate or even obtuse, 43 – 56.5 × 2.5 – 4 cm, 22 – 24 times longer than broad, margins dark glossy green adaxially in fresh leaves, drying medium green, yellowish glossy green abaxially in fresh leaves, drying pale green; midrib rounded abaxially, slightly flattened adaxially; primary lateral nerves 22 – 33 per side, departing the midrib at 40 – 45o angle and joining together in a collective vein about 5 – 8 mm from leaf margin; primary lateral veins and collective veins strongly sulcate adaxially and raised abaxially, minor venation not visible
    Inflorescences
    Inflorescence erect at anthesis, shorter than leaves; peduncle 25 – 27 cm long, terete, longer than petioles; spathe erect for first few days then reflexed, ovate, green or tinged with copper, acutely decurrent at base, rostrate at apex, 4 – 5 × 1 – 1.5 cm; stipe 4 – 6 mm long in front, 1 – 2 mm long at back; spadix longer than spathe, yellow, 5 – 6 cm long, 0.5 – 0.7 cm diam. near middle, obtuse at apex; flowers rhombic, 2 – 3 mm wide in both directions, sides slightly sigmoid; 5 – 6 flowers visible in principal spiral, 4 – 5 in alternate spiral, tepals matt, lateral tepals 1 – 1.5 mm wide, inner margins convex, pistils emergent, flask-shaped, stamens weakly exserted, filaments flattened, translucent, up to 2 mm long, anthers whitish yellow, 0.5 – 0.8 × 0.4 mm, covering the stigma, thecae oblong 0.5 – 0.8 × 0.2 mm
    Infructescences
    Infructescence unknown
    Distribution
    This new species is so far known only from the type locality.
    Ecology
    Anthurium teimosoanum is usually found growing on rocks that are abundant on the forest floor under the canopy. Its inflorescences are very showy because of the yellow spadix.
    Conservation
    The poor state of floristic knowledge about the South Bahian drier forests indicates that the conservation status of Anthurium teimosoanum is best defined as Data Deficient (DD), following the criteria set out by IUCN (2001).
    Note
    Anthurium teimosoanum belongs to sect. Urospadix Engl. and it is here tentatively placed in subsect. Insculptinervia Engl. It can be considered close to A. galeottii C. Koch from Rio de Janeiro, but it differs by the strongly linear leaf blade (not linear lanceolate) and the much shorter petioles that are up to 6 cm long (instead of 40 – 50 cm long). No other species in subsect. Insculptinervia can be confused with A. teimosoanum (the reader is referred to a comparative table of all previously known species of this subsection in Gonçalves 2001). Anthurium teimosoanum can be confused with A. illepidum Schott (included by Engler in subsection Flavescentiviridia, as a synonym of A. longifolium (Hoffm.) G. Don, another species from Bahia. However, A. teimosoanum differs from A. illepidum in the linear (not oblanceolate) leaf blade and yellow (not brown) spadix. In fact, the strongly fragrant yellowish spadix (smelling like decaying pineapple) and linear leaf blade which is distinctly paler on the underside, are rather distinctive characters for this species. A moderate number of fruit flies were seen flying around the inflorescences and they are potential pollinators.
