Monographs Details: Senefelderopsis chiribiquetensis (R.E.Schult. & Croizat) Steyerm.
Authority: Maguire, Bassett. 1965. The Botany of the Guayana Highland. Mem. New York Bot. Gard. 12 (3): 1-285.
Family:Euphorbiaceae
Discussion:There is a conspicuous absence of [male] flowers in the entire collection of this species, so the distinction from other Senefelderopsis must be based upon vegetative characters and on those of the [male] flowers. The leaves are lanceolate-elliptic or lanceolate, acute at the tip and subrounded at the base, 9-15 cm long, 4-8 cm wide, pale yellow below. The [male] spikes are slender, 7-14 cm long. The bracteal glands of cymules are narrow-cylindric. The number of flowers per cymule is 3 (rarely 5). The number of stamens per flower is 3-4. Flowers are distinctly pedicelled, the pedicels being at least twice as long as the flowers and articulate. Capsules are 1.6-2.2 cm long, 1.4-1.5 cm thick, subcylindric, cordate at the base, sharply beaked at the tip, rough, black on the surface. Pericarp is 1.0-1.2 mm thick, ligneous. Seeds are black, shiny, ovoid cylindric, 6-8 mm long, 4-5 mm thick, with a white, 1.2 mm long earuncule at the top.
