Species

Angiosperms > Asterales > Pentaphragmataceae > Pentaphragma

Characteristics

Stem robust, but of unknown stature, 7-12 mm thick in upper part, shaggy. Leaves obliquely obovate, 25-35 by 12-17 cm, base cuneate, apex rounded to subacute, usually very shortly apiculate-acuminate, margin denticulate often revolute, membranous when dry, glabrous above, shortly hispidulo-pubescent below, ± conspicuously crispulous-shaggy along the midrib and larger nerves; nerves c. 6 pairs; petiole robust, 3-5½ cm by 4-8 mm, strongly crispulous-shaggy. Inflorescences arising singly from 1-2 upper axils, at first subscorpioid, soon becoming lax and elongate, 10-12 cm long, 10-20-flowered; peduncle 1.5-2 cm, rhachis up to 7 cm, both shaggy. Bracts broadly ovate to oblong, acute, 10-15 by 3-10 mm, membranous, puberulous on the back. Flowers large, up to 6-7 cm long. Calyx-tube elongate, very narrowly obconic, very gradually widened upwards, 4-5 cm by 3-5 mm, crispulous-floccose. Sepals narrowly or broadly ovate, 13-17 by 4-12 mm, acute, membranous, sparsely crispulous-floccose on the back, otherwise glabrous. Corolla apparently choripetalous, or exceedingly shortly gamopetalous, fleshy, +-crispulous-floccose outside; segments oblong-ellptic, c. 12 by 5 mm, subacute, margins inflexed. Filaments ± 2 mm; anthers linear, ± 3 mm, acute. Style thick, 2-3 mm; stigma cylindric, 5-ribbed, 3 by 1.5 mm.
