Species

Angiosperms > Asterales > Pentaphragmataceae > Pentaphragma

Characteristics

Stem 12-30 cm long, glabrous, or sometimes +-furfuraceo-puberulous on the young parts. Leaves rather small, obliquely ovate to (more often) ovate-lanceolate, 8-15 by 3-5 cm, base de-current-cuneate, more rarely +-rounded, apex gradually attenuate-acuminate, margin very shortly obtusely undulate-dentate and often revolute, glabrous above or (especially on the nerves) sparsely and minutely puberulous or very minutely granulose-papillose, mostly thin in texture; nerves 2-3 pairs, little curved; petiole 1-2.5 cm, slender, glabrous or sparsely furfuraceo-puberulous. Inflorescences arising singly or in pairs from the 1-4 middle or upper (but not uppermost) leaf-axils, small, capitate, not scorpioid, c. 1 cm diam., 2-10-flowered, peduncle c. 5 mm, glabrous. Bracts glabrous, the lowest ovate-lanceolate, 7 by 3 mm, acute, the upper ones decreasing rapidly in size. Flowers c. 1 cm long. Calyx-tube 5-6 by 3-4 mm, glabrous. Sepals c. 3 by up to 2 mm, obtuse. Petals c. 3 by almost 2 mm, obtuse or slightly cucullate, reflexed. Stamens c. 1.5 mm long; anthers oblong. Style thick, 1-1.5 by 1 mm; stigma very thick, 1.25 by 1.25 mm. Fruit ellpsoid, 7-8 by 4-5 mm, glabrous.
