at base, penninerved (principal secondary nerves three or four pairs),
entire, membranous; peduncles solitary, up to 3 cm. long; bracts
broadly ovate, 5 to 6 cm. long, 3.5 to 4.5 cm. wide, acuminate, free
nearly to base, glabrous except for a band, 3 to 4 mm. wide, of short
tomentum at margin of inner surface; flowers 5 to 7 cm. wide;
sepals oblong-lanceolate, 3 cm. long, 1 cm. wide, corniculate on outer
surface just below apex; petals as long as and slightly narrower than
the sepals; corona in several series, the outermost filaments subulate,
1 to 1.5 cm. long, enlarged at base, the succeeding 5 or 6 series 1 to 2
mm. long; operculum membranous at base, filamentose, the filaments
erect, about 7 mm. long, the tips incurved; limen membranous,

TYPE LOCALITY: Near Tumbala, Chiapas, Mexico.
ILLUSTRATION: Contr. U. S. Nat. Herb. 5: pi. 17.
DISTRIBUTION: Southern Mexico and northern Guatemala.
MEXICO: Tacoba, Liebmann (V). Chiapas: Tumbala, 500
meters, Nelson 3325 (N, type).
GUATEMALA: Alta Verapaz: Coban, 1,325 meters, Tilrckheim 687

From P. ligularis, the only other species of this group found in
Mexico and Guatemala, P. Nelsoni is at once distinguished by its
saucer-shaped petiolar glands, much larger bracts, and long-
sessile,
filamentose operculum.
The last feature likewise distinguishes the
plants from South American species of this immediate relationship.
