Discussion

  • The description is from Burret (1932) and Moore (1980). C. angustisecta has been cultivated for many years in southern Florida as C. leonis. Moore (1980) described and named C. leonis from plants cultivated in Miami, Florida that were grown from seeds collected in Bolivia. On the eastern Andean slope where C. angustifolia is native in Bolivia and Brazil, local inhabitants gather the inflorescences and take them indoors to perfume their houses.
    Apparently only cultivated in southern Florida where it is found sparingly in a few collections and gardens, C. angustifolia is an attractive plant with mottled green leaf sheaths and petioles, intensely fragrant, bright orange staminate flowers, and black fruits.

Pistillate solitary at node; peduncle 66-70 em long; bracts 58, similar to those of the staminate; rachis 2.5-10 cm long; rachillae 6-16, 7-20 cm long, 4 mm diam., orange in fruit, erect to spreading. Flowers: Staminate in loose spirals, 4 mm long, orange, intensely fragrant; calyx 1.5-2 mm high, deeply lobed, light green in bud, orangish with dark brown margin at anthesis, sepals connate basally, rounded apically; petals 3-4 x 2-2.4 mm, ovate, valvate, free, smooth externally, grooved internally, dark green in bud, orange at anthesis; stamens 2.6 mm long, shorter than pistillode, 1/2 as high as petals, filaments 2 mm long, anthers 1.2 mm long, briefly bifid apically and basally, lilac; pistillode 3.5 mm high, columnar, 3-lobed apically. Pistillate in spirals, sessile, leaving round scars, yellow-green; calyx 2 mm high, adnate to receptacle for 1 mm, deeply lobed, green, sepals broadly rounded apically; petals 2.5 x 2 mm, adnate for 1mm to receptacle, imbricate basally, valvate, erect to spreading apically, not prominently nerved; staminodes lacking; pistil depressed-globose, 3-lobed, stigma lobes sessile, short, erect. Fruits: 15-18 x 8 mm, ellipsoid, black, mesocarp 0.5 mm thick, pale with long flat fibers; seeds 15 x 5 mm, ellipsoid, subfalcate. (Hodel, D. 1992.
