Pentaphragma jaherii Airy Shaw

Species

Angiosperms > Asterales > Pentaphragmataceae > Pentaphragma

Characteristics

Stem dwarf, 5 cm by 3-4 mm, ± densely cris-pulo-pubescent above. Leaves subfalcately ovate-lanceolate, 1½-9 by 3½-4½ cm, rounded or subcordate at base, gradually narrowed into the subobtuse or subacute apex, margin narrowly revolute, apparently entire but probably actually very minutely crenulate, thickish in texture, distinctly rounded-papillose below, glabrous except for the nerves sparsely puberulous below; nerves 3-5 pairs; petiole slender, 8-13 by 2 mm, puberulous. Inflorescence apparently solitary on each stem, arising from a subterminal axil, compact, scarcely evidently scorpioid, 2 cm diam.; peduncle 1 cm, pubescent. Bracts rather large in proportion, broadly ovate or suborbicular, up to 10 by 8 mm, membranous, crispulo-puberulous, conspicuously laciniate-ciliate or fasciculate-pilose on the margin. Flowers 9-12 mm long. Calyx-tube campanulate or oblong-ovoid, 4-6 by 3-4 mm, puberulous. Sepals very unequal: smallest one oblong-ellptic, 4 by 1.5 mm, largest suborbicular, 4-5 mm diam.; remainder intermediate; all membranous, crispulo-puberulous, erose-ciliate. Petals free (or possibly arising from a membranous annulus?), elliptic-oblong, 4 by 1.5 mm, delicate in texture, margins inflexed, subciicullate at apex, crispulo-puberulous on back. Filaments 1.5 mm; anthers linear, 1 mm. Style broadly conical, 1 mm long; stigma conical, 1 mm long.
