This species is related to P. menispermifolia and P. nephrodes,
but differs from both in having essentially entire leaves. In addition,
the bracts of P. menispermifolia are much narrower and glandulardenticulate,
and in P. nephrodes the petiolar glands are much more
slender. The specimens examined are all in fruit, with badly
withered floral parts, so that an accurate description of the coronal
structure is not possible.
Apparently the outermost corona filaments
are much shorter than in P. menispermifolia or P. nephrodes.

Plant densely hirsute throughout; stem subangular; stipules
subreniform, 1.5 to 2 cm. long, 0.8 to 1 cm. wide, aristate, coarsely
serrate-dentate; petioles 1 to 2 cm. long, bearing near the middle 2
or 3 stipitate glands 2 to 3 mm. long; leaves 6 to 13 cm. long, 5 to
9 cm. wide, 3-lobed (middle lobe ovate or ovate-lanceolate, 3 to 5
cm. wide, one-half to two-thirds the length of the blade, acute or
subobtuse, the lateral lobes deltoid-ovate), subcordate, denticulate;
peduncles 4 to 6 cm. long, in fruit much longer; bracts borne about
3 mm. below the base of the flower, ovate-lanceolate, 1 to 2 cm. long,
0.7 to 1 cm. wide, serrate; flowers 6 to 8 cm. wide; sepals oblong, 3 to
3.5 cm. long, 1 to 1.2 cm. wide, obtuse, dorsally awned just below
apex; petals linear-oblong,
slightly shorter and narrower than the
sepals; corona filaments filiform, in several series, the outermost 2.5
to 3 cm. long, radiate, proximally purple, distally white, those of the
succeeding series 3 to 6 mm. long, erect; operculum membranous at
base, filamentose above, the filaments 5 to 8 mm. long; limen membranous,
3 mm. high, closely surrounding the base of the gynophore;
ovary ovoid, hirsute; fruit ovoid, about 4 cm. long and 2 cm. in
diameter, narrowed at base; seeds obovate, about 6 mm. long and
3 mm. wide, reticulate.
