The exact identity of P. tiliaefolia is by no means clear. Apparently
both Linnaeus and Cavanilles knew the plant only from the
description and figure given by Feuille"e. This description in general
would apply almost equally well to either P. ligularis, entire-leaved
forms of P. triloba, or the specimens cited above.
thus:
The differences between these three species may be summarized
P. ligularis
Stipules ovate-lanceolate
or oblong-lanceolate.
Petiolar glands filiform
or narrowly liguliform,
3 mm. long or more.
Leaves usually not lobed,
entire at margin. Basal
lobes not overlapping.
Bracts less than 4 cm.
long, united one-fifth
to one-third.
Corona 5-ranked, the 2
outer ranks subequal to
petals, the 3 inner
ranks much shorter.
Operculum denticulate.
P. triloba
Stipules ovate-lanceolate.
Glands saucer-shaped,
stipitate, less than 3
mm. long.
Leaves usually 3-lobed,
minutely denticulate.
Basal lobes overlapping.
Bracts more than 4 cm.
long, free or united
only at very base.
Corona 3-ranked, the
outermost rank half as
long as petals, the
second rank minutely
denticulate.
Operculum crenulate.
P. tiliaefolia
Stipules ovate-lanceolate
or oblong-lanceolate, or
the upper narrowly
linear-lanceolate. l
Glands saucer-shaped,
subsessile or short-stipitate,
less than 3 mm.
long.
Leaves never (or rarely?)
lobed, entire at margin.
Basal lobes overlapping.
Bracts less than 4 cm.
long, united one-fifth
to one-half.
Corona 5-ranked, the 2
outer ranks about half
as long as petals, the
3 inner ranks much
shorter.
Operculum entire.
Plate 12 is lacking from the copy of FeuilleVs work which I consulted
;
I assume that Cavanilles' illustration arid the figure of a leaf in
the Amoenitates are substantially accurate reproductions. In both of

In the Pav6n plant of P. tiliaefolia in the British Museum the lower stipules
are ovate-lanceolate, about 3 cm. long, 1.5 cm. wide, the upper linear-lanceolate,
1 cm. long, 0.4 cm. wide. The specimen of this same collection at Berlin has linearlanceolate
stipules, 2 cm. long, 0.2 cm. wide. In the Colombian material the
stipules are uniformly ovate-lanceolate.
