Species

Angiosperms > Asterales > Pentaphragmataceae > Pentaphragma

Characteristics

Stem c. 10 cm high, glabrescent below, crispate-setulose above. Leaves obliquely broad-ovate, 13-19 by 8-11 cm, rather broadly cuneate at base, almost rounded at apex and narrowed into a very short subacute cusp (sometimes almost absent), very obscurely shallowly sinuate-crenulate, glabrous above, shortly pubescent on the nerves below; nerves 2-4 pairs; petiole slender, 2-3 cm, glabrescent. Inflorescences arising singly from 1-2 of the upper axils, shortly and densely scorpioid, 2.5-3 cm long, c. 12-14-flowered, peduncle 5-10 mm. Lower bracts broadly elliptic-ovate, c. 8 by 6-8 mm, membranous, pubescent, the upper ones smaller. Pedicels almost none. Calyx-tube ellpsoid, 3 by 7½ mm, pubescent. Sepals 5, obovate or spatulate-obovate, c. 5 by 2-3 mm, obtuse, membranous, hispidulous, ciliolate. Corolla segments 4, rarely 5, almost free or very shortly connate at base, unguiculate-spatulate, the 'claw' erect, broadly oblong, 2 mm, the 'limb' ± spreading or recurved, ± flat or somewhat twisted, broadly elliptic, 3 by 2.5 mm, subacute, margin quite entire and conspicuously pale when dry, as though cartilagineous. Filaments slender, 1 mm, anthers linear, 2 mm. Stigma sessile or subsessile, thickly pileiform or subcerebriform or excavated at the summit, 1 by 1½-2 mm. Fruit ellpsoid, 8-10 by 3-4 mm, sparsely pubescent.
