Passiflora lancifolia   is very similar to another Jamaican endemic, Passiflora macfadyenii   . They both possess bright red, elongated tubular flowers that are likely pollinated by hummingbirds. The two species can be easily separated utilizing both vegetative and reproductive characters. Passiflora lancifolia   possesses shallowly trilobed leaves (rarely unlobed) with the lateral lobes commonly significantly less than half the length of the central lobe, and the central lobe is ovate and never narrowed at the base. Passiflora macfadyenii   possesses distinctly trilobed leaves with the lateral lobes commonly more than half the length of the central lobe, and the central lobe is obovate with a distinctly narrowed base similar to that in Passiflora juliana   and Passiflora viridiflora   . The pedicels in Passiflora lancifolia   are greater than 2.3 cm long, whereas those of Passiflora macfadyenii   rarely exceed a length of 1.8 cm. The floral nectary of Passiflora lancifolia   is the widest in the supersection, greatly exceeding that of Passiflora macfadyenii   . The outer coronal filaments are connate and often not adnate to the sepals or barely so in Passiflora lancifolia   , whereas those of Passiflora macfadyenii   are distinctly adnate to the sepals. Passiflora lancifolia   often has two rows of coronal filaments (rarely with one row or a poorly developed inner row) and Passiflora macfadyenii   lacks an inner coronal row (or with a poorly developed second coronal row seen in one flower from a plant in cultivation, i.e., MacDougal 452 - cultivated from cuttings of Thomas 2032). The fruits of Passiflora lancifolia   and Passiflora macfadyenii   are distinct, with Passiflora lancifolia   having globose fruits and Passiflora macfadyenii   possessing fusiform fruits. The habitats of the species are also different with Passiflora lancifolia   growing in tropical lower montane mist forests at 850-1220 m and Passiflora macfadyenii   found in tropical dry forests at 200-310 m.

The name Passiflora lancifolia   was originally published by Hamilton as " Passiflora lancifolia   Herb. Prof. Desv.," and the species has often been cited as " Passiflora lancifolia   Desv. in Ham." or " Passiflora lancifolia   Desv. ex Ham." However, in the preface of his book, it appears that Hamilton himself took responsibility for the new species and genera described therein and only acknowledged the advice and assistance of Desvaux (see MacDougal and McVaugh 2001 for further details). Soon afterwards, Don (1834) described the taxon Passiflora lanceolata   . However, Don’s description of Passiflora lanceolata   is identical to that of Passiflora lancifolia   in Hamilton and is based upon the same type material, therefore, the name Passiflora lanceolata   G.Don is a nomenclatural synonym of Passiflora lancifolia   Ham. In 1850, Macfadyen wrote his second volume of Flora of Jamaica and included in it the description of a different plant, which he called Passiflora regalis   , now known as Passiflora macfadyenii   C. D. Adams. However, Macfadyen unexpectedly passed away before the publication of his flora, though it was distributed. As a result, several authors viewed the new species that were described by Macfadyen as ineffectively published and began to publish new species based upon his work. Grisebach (1860) was one of these authors and published a description of Passiflora regalis   , which he attributed to Macfadyen. However, the species that he described was Passiflora lancifolia   and not Macfadyen’s Passiflora regalis   . In addition, Ramírez Goyena (1909) published a description of Passiflora regalis   , which he attributed to Macfadyen, but the species that he described was also Passiflora lancifolia   and a later homonym of Passiflora regalis   Macf. ex Griseb. Incidentally, Ramírez Goyena’s description of Passiflora regalis   , other than being in Spanish and not in English, is virtually identical to that of Grisebach.

Killip (1938) placed Passiflora lancifolia   together with Passiflora viridiflora   in the subgenus Chloropathanthus   . However, the discovery of Passiflora juliana   , a species that very closely resembles Passiflora viridiflora   but is clearly a member of supersection Cieca   , reinforced MacDougal’s hypothesis ( 1983) that the apetalous, tubular-flowered species (including Passiflora lancifolia   ) belong in supersection Cieca   ( MacDougal 1983, 1992).

Benson et al. (1975), in a study of the coevolution of plants and herbivores, reported that Dryas julia   is an herbivore of Passiflora lancifolia   .
