3 to 4 cm. long, glandless; leaves broadly ovate, 7 to 8 cm. long, 6 to
7 cm. wide, very obscurely 3-lobed (middle lobe deltoid, obtuse,
mucronulate), or with a single lateral lobe, peltate about 1.2 cm.
from the truncate base, quintuplinerved, dark green above, glaucous
beneath; peduncles about 8 cm. long; bracts 2, cordate, about 5 cm.
long and 4 cm. wide, entire, thin-membranous; flowers 3.5 to 4.5
cm. wide, white; sepals ovate-lanceolate, 1.5 cm. long, 1 to 1.2 cm.
wide, obtuse, radiate; petals ovate-lanceolate, 1.5 cm. long, 0.8 cm.
wide, abruptly narrowed at base, obtuse, white, spotted with red;
corona filaments in 2 series, the outer 1 cm. long, dilated at apex,
the inner barely 3 mm. long, capitate; operculum membranous,

TYPE LOCALITY: Finca Sepacuite", Department of Alta Verapaz,
Guatemala.
DISTRIBUTION: Southern Mexico and northern Guatemala.
MEXICO: Veracruz: Rio de Puerto Moneda, Sierra Grande del
Sur, Purpus 10357 (N).
GUATEMALA: Alta Verapaz: Finca Sepacuite*, Cook & Griggs
593 (type).
At the time this species was described its bracts were unknown,
though its relationship with P. Hahnii was obvious. The Purpus
specimen has an involucre of two large bracts, which completely
lack the setiferous lobes of those of P. Hahnii. Additional points
of differentiation are the larger crenate stipules and the smaller flowers
of P. Cookii.
