Pentaphragma spatulisepalum Airy Shaw

Species

Angiosperms > Asterales > Pentaphragmataceae > Pentaphragma

Characteristics

Stem 10-20 cm long, slender, glabrous. Leaves subfalcately elliptic or ovate, 11-18 by 5-6.5 cm, cuneate-attenuate at base, attenuate, subacuminate and acute at apex, margin undulate-serrate, very thin in texture, quite glabrous; nerves 2-4 pairs; petiole very slender 1.3-2 cm. Inflorescences arising singly from the 1-3 uppermost axils, 6-12-flowered, rather lax, not scorpioid at anthesis, 2-3 cm diam.; rhachis up to 1.5 cm; peduncle 5 mm, minutely ramentaceous-hispidulous. Bracts linear-spatulate (except for the lowest which is elliptic-oblong), c. 10 by 1-2 mm, attenuate at the base into a 2-3 mm long petiole, obtuse or emarginate at apex, membranaceous, glabrous. Pedicels slender, 2-3 mm, glabrous. Flowers 8-10 mm long, glabrous. Calyx-tube narrowly ellpsoid, 4-5 by 1-2 mm. Sepals spatulate-oblong, 5-6 by 1.5-2 mm, obtuse or retuse, erect or slightly patent, less unequal than in most species. Corolla 4-5 mm long, gamopetalous to beyond the middle; segments oblong-ovate, 1.3 mm wide, subobtuse, erect, recurved at apex. Filaments c. 2 mm; anthers oblong, 1 mm. Style 1.5 mm; stigma thickly pentagonal-discoid, 1 by 0.8 mm, 5-lobulate. Fruit ellpsoid, 7-8 by 3-4 mm, attenuate at base.
