prostrate to ascending, 15–50 cm, strigose to short-sericeous when young, glabrate with age.

opposite;

stipules distinct (lower side) or connate (upper side), usually inconspicuous, filiform to triangular-subulate, 0.5–1 mm, strigose to short-sericeous;

petiole 1–2 mm, strigose to short-sericeous;

blade usually ovate to oblong, rarely linear or spatulate, 2–37 × 1–10 mm, base oblique to subsymmetric, cuneate to slightly rounded or cordate, margins entire, apex acute, adaxial surface sometimes with reddish blotch in center, both surfaces strigose, short-sericeous, or tomentose to glabrate;

venation palmate at base, pinnate distally, only midvein conspicuous.

campanulate, 1.5–2 × 1.2–1.6 mm, closely strigose to short-sericeous to glabrate;

glands 4, usually dark purple, rarely green-brown, oblong, 0.5 × 0.7–1.3 mm;

appendages absent or white, ± unequal, irregular or rudimentary, 0.6–1 × 1–1.5 mm, distal margin entire or crenately lobed.

columella (1.4–)1.8–2 mm.

white, slender ovoid, 3-angled to almost round in cross section, 1.2–1.6 × 0.6–0.7 mm, with 4–5 rounded, transverse ridges encircling seed.

pediculifera can be variable in terms of leaf shape and the extent of pubescence, but the species is readily identified by the short, appressed hairs on the leaves and the distinctive seed that is encircled by a series of round, transverse ridges.

solitary at distal nodes;

peduncle 0.5–1.5 mm.
