AMERICAN PASSIFLORACEAE 387
banded with blue and white, the filaments of the inner series densely
massed, erect, 2 to 5 mm. long, blue; operculum membranous in
lower half, filamentose in upper half; nectar ring annular; limen
cupuliform; ovary ovoid, tomentulous; fruit globose, about 4 cm.
in diameter, very acid, the pericarp brittle; seeds obcordate, about
10 mm. long, 7 mm. wide, strongly flattened, broadly wing-margined,
punctate at center.

The taxonomic position of this species is doubtful. The
broadly
winged seeds at once suggest a close relationship with P. quadrangularis,
but in no other detail are the two species alike. The shape
and serrulation of the leaves are strongly suggestive of P. serratodigitata,
but the bracts, more like those of P. edulis, and the coronal
arrangement are quite different. Masters placed the species near
P. violacea and P. amethystine,, in the group with large, foliaceous,
subreniform, persistent stipules, but the stipules are very small and
early deciduous. In the present treatment P. filamentosa is $aced
near P. cincinnata, though it differs in several important details.
Perhaps it is a hybrid between P. caerulea and P. serrato-digitata.
Passiflora filamentosa has been frequently cultivated in Europe,
but, as Masters observed, specimens of positively native origin are
very rarely found in herbaria.
The type, in the Cavanilles Herbarium, is in a fine state of
preservation, agreeing perfectly with Mrs. Chase's specimen from
Minas Geraes, which was collected in a very dense jungle, with every
indication that the plant was native. Regarding the origin of the
type specimen Cavanilles says, "In America. Colui in horto Issy.
Exc. Ducis ab Infantado."
Passiflora cuneifolia, considered by Masters as possibly identical
with P. edulis, I take to be a form of P. filamentosa with 3-lobed
leaves, though perhaps it is a hybrid between P. filamentosa and
P. caerulea.
