This group of granadillas, with small stipules and glabrous,
laurel-shaped leaves, which are here brought together in the series
Laurifoliae, is an exceedingly difficult one, due to a general similarity
in the shape of the leaves and to the absence of any indument on the
vegetative parts by which ready distinctions can be made. The
species appear to fall into two main groups, one with the outermost
series of corona filaments much shorter than the next series (the
difference well shown in Popenoe's illustration of P. Popenovii in
Contr. U. S. Nat. Herb. 24: pi. 42), the other with the outermost
filaments equaling or exceeding those of the next series. In the
first group the species all have pubescent ovaries; in the second, the
ovary is pubescent in P. riparia, P. tolimana, P. acuminata, and P.
Gleasoni and glabrous in the four other species. The species of the
first group, with the exception of P. nigradenia, differ in only minor
characters but these differences correlate well with the geographical
distribution of the species. In P. ambigua, from Central America,
the glands are borne below the middle of the petiole, and there is a
distinct space between the second and the third row of corona filaments.
In P. laurifolia the glands are borne near the apex of the
petiole, and the third row of filaments is situated close to the second
row. Passiflora nigradenia has a coronal structure very different
from any of these.
Passiflora tinifolia appears to be this species. The type, collected
in French Guiana by Richard, is not in the Jussieu Herbarium at
Paris. Jussieu states that P. laurifolia differs from P. tinifolia in
having leaves emarginate at the base, petioles glandular at the apex,
not at the middle, and more deeply crenate bracts, which are as
long as the sepals (much shorter than the sepals in P. tinifolia).
