result of introduction by humans. However, the center of diversity is in southern
México and northern Central America.
Of the 19 species recognized here, five species (P. juliana, P. viridiflora, P.
mcvaughiana, P. tacana and P. itzensis) are endemic to México, two to
Guatemala (P. clypeophylla and P. trinifolia), two to Jamaica (P. lancifolia and P.
macfadyenii), and one to the Galapagos Islands, Ecuador (P. tridactylites).
Passiflora juliana and P. viridiflora are both found along the Pacific coast and in
the Pacific coastal plain of southwestern México in disturbed tropical deciduous
or semideciduous forests of low to moderate elevation (Fig. 8.24). These two
species are not sympatric, with P. juliana found farther north, from areas around
the Bahia Chamela in Jalisco to those just south of Manzanillo in southern
Colima, and P. viridiflora occurring from regions just north of Lazaro Cardenas in
Michoacan to areas around the Gulf of Tehuantepec in southern Oaxaca.
Passiflora itzensis is found in tropical semideciduous forests from areas near
Chichen Itza in Yucatán to localities in southern Quintana Roo north of Chetumal
(Fig. 8.37). Passiflora mcvaughiana is also found in southwestern México, in
high elevation oak, pine/oak or pine forests or montane mesophytic forests on
moist hillsides and in barrancas (Fig. 8.24). Passiflora tacana is known only from
one collection in a high altitude tropical montane forest on Volcán Tacaná in
Chiapas, México along the border with Guatemala (Fig. 8.29). Passiflora
clypeophylla has not been found since the type was collected in 1889 (Fig. 8.18).
It is a plant of moderate elevation (ca. 762 m. alt.) and, based upon information
about the ecology of the area, was likely found in seasonally dry areas
