284. Passiflora aristulata Mast, in Mart. Fl. Bras. 13, pt. 1:
570. 1872.
Plant glabrous throughout; stem terete, slender; stipules cordate
or semicordate, 10 to 15 mm. long, 8 to 10 mm. wide, aristulate;
petioles 2 to 3 cm. long, filiform, biglandular near middle, the glands
about 1 mm. long; leaves 3-lobed about to middle, 3 to 4 cm. along
midnerve, 1.5 to 2.5 cm. along lateral nerves, 4 to 6 cm. between
apices of lateral lobes (lobes broadly oblong-lanceolate, 1 to 1.5 cm,
wide, entire, subequal, the lateral lobes horizontally divergent) ;
petioles 1.5 to 2 cm. long; bracts broadly ovate, about 10 mm. long;
8 mm. wide, cordulate, sessile, borne at base of flower, thin-membranous;
flowers 3 to 4.5 cm. wide; calyx tube campanulate; sepals
oblong, 1.2 to 2 cm. long, 4 to 6 mm. wide, cucullate, dorsally minutely
subulate-mucronate, conspicuously reticulate; petals ovatelanceolate,
slightly shorter than sepals, obtuse, purplish (?); corona
filaments in 4 series, the outer 2 filiform, about half as long as the
petals, those of the inner 2 series narrowly linear, subclavate, about
1 mm. long; operculum membranous, fimbriate in upper half, the
fringe 1.5 to 2 mm. long; limen cupuliform, closely surrounding

The three Peruvian species, P. tarapotina, P. subulata, and P.
aristulata, have leaves of rather similar outline, though in P. aristulata
the lateral lobes are horizontally spreading, ascending in the two
others. The flowers of the three, however, differ markedly. Passiflora
tarapotina has a well developed calyx tube, and belongs to the
subgenus Granadillastrum. Passiflora aristulata may be distinguished
from P. subulata by the shorter tips of the sepals and by its different
coronal structure.
Passiflora aristulata is known only from northern Peru.
