Vernacular Names 414 Mac-xiquin-zootz (México) and xiikzodz (México). Additional Specimens Examined México. –QUINTANA ROO: Puerto Morelos, Jardín Botánico Benito Juárez, 3-8 m, Escalante 127 (CICY); along MÉXICO 307 between Chetumal and Cancún, 18º56.71N, 88º11.34W, 20 m, Porter-Utley & Mondragón 395 (CICY). – YUCATÁN: Chichén Itzá, near Pisté, Lundell & Lundell 7375 (MICH); Mpio. Tinum, A 3 km de Tinum rumbo a San Francisco, 23 m, Ucan 2303 (CICY). Cultivated material. cultivated at Duke University 1989-1992 from a cutting collected in 1989 by Sr. Dzib and E. Leiter at Chichén Itzá, MacDougal 4633 (MO). Notes In 1992, MacDougal noticed marked variation in reproductive and vegetative characters among the herbarium specimens circulated as P. coriacea from Belize, Guatemala, and the Yucatán Peninsula of México and described P. xiikzodz. He found the floral corona of this new species to be fundamentally different from P. coriacea and the other members of supersection Cieca, as it is 5-7-seriate as opposed to 2-seriate. He noticed the absence of the floral nectary and the very reduced, denticulate operculum of this species. The seeds are also longer than all of the other species in the supersection. The petiolar nectaries are positioned on the distal third of the petiole in P. xiikzodz and the floral stipe is diagnostically long. These floral and vegetative characters clearly separate this
415 species from other members of supersection Cieca. MacDougal further separated P. xiikzodz into two subspecies, P. xiikzodz ssp. xiikzodz and P. xiikzodz ssp. itzensis. Though he found numerous differences in the flowers of the two subspecies and artificial cross-pollinations between them proved unsuccessful, he felt that more information was needed to support the recognition of two separate species. I recognize the two species, P. xiikzodz and P. itzensis, not only based upon the detailed studies of MacDougal (1992), but also because my morphological and molecular analyses of the taxa support their recognition (see chapters 4 and 6). Passiflora itzensis and P. xiikzodz are identical vegetatively, but the flowers are quite different. The flowers of P. itzensis lack or have a greatly reduced dark reddish purple androgynophore, are smaller, possess fewer filaments in the outer and second coronal rows, an androecium and gynoecium with reddish purple pigmentation, very short styles, stigmas with their receptive surfaces presented distally, and anthers that do not flip over to an extrorse position after the flower buds open but move only slightly from the original introrse position to present their pollen distally. In the herbarium, it is not necessary to have perfectly preserved flowers to differentiate between P. itzensis and P. xiikzodz, as the floral stipe of P. itzensis is commonly shorter than that of P. xiikzodz. Incidentally, in the dried flowers of both P. itzensis and P. xiikzodz, the coronal filaments appear nearly black. MacDougal noticed the occasional appearance of one or two small but well- formed petals in cultivated material of P. itzensis (MacDougal 4633) (MacDougal,
