  • Description

    Author : Juan Francisco Morales, Xavier Cornejo & Reinaldo Aguilar.

    Description: Epiphytic herbs, pendulous from trees in branching strands of several meters long. Stem sympodial, less than 1 mm diam., the internodes 3-6 cm long with only extreme base covered by leaf-sheath, strongly curved; pseudo-axillary branches actually a continuation of main axis, very short and concealed by basal leaf-sheath, bearing 2-3 leaves. Leaves distichous-ranked, 25-50 mm long, densely cinereous-lepidote or ferrugineous-lepidote; blades filiform. Scapes practically absent, inflorescences reduced to single pseudo-lateral flowers. Floral bracts ovate, shorter than sepals, densely lepidote, the apex apiculate or caudate. Flowers sessile; sepals narrowly ovate, 7-9 mm long, strongly nerved, the apex acute; petals narrow, 9-11 mm long, pale green or blue; stamens deeply included. Fruits capsules, ca. 20-25 mm long. Seeds with white coma (fide Smith & Downs, 1977).

    Common names: Barba (Spanish), barba de palo (Spanish), barba de viejo (Spanish), spanish beard (English), spanish moss (English).

    Distribution: Southeastern United States (Florida) and Mexico to northern Chile, Argentina and the West Indies from sea level to ca. 3500 m (Smith & Downs, 1977).

    Ecology: In dry, moist and wet forests, persistent in very disturbed habitats (Cornejo, pers. obs. 1993-2000).

    Phenology: This species has been observed with fruits throughout the year.

    Pollination: No observations recorded.

    Dispersal: Wind dispersed.

    Taxonomic notes: This species is recognized by the filiform grayish leaves and the very elongated wiry stems that form masses. It is often mistaken as a lichen or a moss.

    Conservation: Not endangered.

    Uses: Tillandsia usneoides is used as an ornamental. In many Latinamerican countries it is often used as a Christmas decoration.

    Etymology: The lichen epithet usneoides (the fake Usnea) refers to the resemblance of this species with lichens of the genus Usnea (Parmeliaceae).
