Notes.
This species has the longest wide infundibular white flowers in the whole tribe
Bignonieae
, with corollas up to 35 cm long (
Gentry 1997
,
Howard 1989
). It is most morphologically similar to
T. crucigerum
, with which it shares ellipsoid fruits that bear wingless woody seeds (Tab.
1
).
Tanaecium jaroba
differs from
T. crucigerum
by the glabrous or pubescent leaflets abaxially (vs. whitish-tomentose leaflets abaxially in
T. crucigerum
).
