Passiflora ampullacea Although this species is very little known, some botanists who have eaten the fruits and seen the plant's vigorous growth consider it to be a promising future crop. The fruits are much larger than those of the curuba and the rind is thicker, which protects the fruit on the way to market. The common name in central Ecuador, to which the species is endemic, is gulin. This species also hybridizes easily with P. mollissima. 17

Passiflora tripartita This plant (which may not be a distinct species but a variety of the curuba) grows all over Colombia and has fruits as good as those of curuba.

Passiflora mixta (the curuba de Indio of Colombia).

Passiflora ambigua (Colombia, a fruit much like the curubejo).

Passiflora mandonii (Bolivia) a close relative of the galupa, but with longer fruit.

PROSPECTS

Andean Region. With the rising international interest in passionfruits, the Andean native species are a resource of large potential. They seem ripe for research and could be increasingly used locally as well as becoming valuable exports. Horticultural and marketing analyses, trials, and comparisons should be undertaken quickly. It seems probable that many of the Andean species initially will be low yielding, although they are likely to show outstanding response to modern methods and research.

There is little factual information available on the Andean passionfruits. This must be generated by comparative tests in the areas where these species are available. Research institutes in Bolivia, Peru, Ecuador, Colombia, and Venezuela could provide information that may be useful as the basis for industrial development. The future of these fruits will depend upon horticultural development. The production of pulp and concentrate has extremely good prospects if commercial-scale production can be established and maintained.

Passionfruits seem particularly suited to countries with inexpensive labor because the fruits have to be picked by hand and must be grown on supports such as trellises.
