Passiflora riparia appears to be the commonest representative
of this series in the upper and middle Amazon Valley, many specimens
hitherto considered P. laurifolia evidently belonging here.
Though in the shape of the leaves and in the indument of the ovary it
closely resembles P. laurifolia, the corona filaments are much longer
and the two outer series are subequal. Another species witlTwhich
P. riparia may easily be confused is P. nitida, but in that the ovary
is glabrous, the corona filaments are somewhat slenderer, and the
whole plant usually becomes very dark upon drying. A mark that
may serve to distinguish P. riparia from all its allies is the grouping
of the flowers in clusters on short, axillary, leafless branches. However,
as only one of the flowers on the branch may develop or persist,
this character can not always be relied upon.
Ducke 24044, Swallen 3309, and certain other specimens from
the middle Amazon are doubtfully referred here. The glands are
borne at the apex of the petiole and the leaves are narrow, yet the
flowers seem indistinguishable from those of P. riparia. A note
accompanying the Ducke specimen states that the mature fruit is
citron-colored, with a very acid, nonedible pulp.
