Revision of Passiflora Subgenus Decaloba ... - Passion Flowers

In 1805, Antoine Laurent de Jussieu formally described 13 new species of the
genus, including Passiflora coriacea; he also recognized the genera Murucuia
and Tacsonia. Because of its tubular flowers, he placed the apetalous P.
viridiflora in the genus Tacsonia. In this treatment, Jussieu also discussed in
great detail questions of generic delimitation and relationship, and he was the
first to suggest that Passiflora, Murucuia, and Tacsonia should be placed
together in their own family. However, Jussieu did not use a family name in the
official sense (Jussieu, 1805a, 1805b). Henri Francois Anne de Roussel, in
1806, was the first to validly publish the family Passifloraceae, with credit to
Jussieu. Until recently, the first valid publication of the Passifloraceae was
attributed to Carol Sigismund Kunth (1817); however, Roussel’s description of
the family was pubished more than ten years before Kunth’s. Incidentally, Kunth
also published the species P. tubiflora but was probably unaware that Cavanilles
had already named it P. viridiflora (Humboldt, Bonpland & Kunth, 1815-1825). In
1826, Kurt (Polycarp Joachim) Sprengel transferred P. viridiflora into the genus
Murucuia (Sprengel, 1826). One year later, William Hamilton, in his Prodromus
Plantarum Indiae Occidentalis, described three new species of Passiflora. One
of these, P. lancifolia Ham., is a red, apetalous, hummingbird-pollinated member
of supersection Cieca from the Antilles (Hamilton, 1825).
In 1828, Augustin Pyramus de Candolle subdivided Passiflora into eight
sections based upon bract and calyx morphology: Astrophea, Polyanthea,
Tetrapathaea, Cieca, Decaloba, Granadilla, Tacsonioides, and Dysosmia; he
thought that all members of the tribe Passifloreae lacked a corolla. He placed all
