PASSIFLORACEAE
Passiflora multijlora Linnaeus, of Costa Rica and Greater
Antilles, was cited for Dominica by Grisebach (1860:291),
based on Linnaeus’ citation of the type locality as “Dominica.”
The type locality is surely the Dominican Republic in
Hispaniola, as concluded by Killip (1938:77).
Passiflora vitifolia Kunth, with large, scarlet flowers and
3-lobed leaves, was cultivated at Lisdara Estate (Hodge 2418).
