Ref. Dransfield, 1982: 456.
Habit. Liana 20 m high.
Habitat. Forest and roadsides.
Distribution. Guinea-Bissau to Congo (Kinshasa).
Local distribution. Ndakan.
Phenology. Flower: April.
Note. Tuley (1995) describes the position of the leaflets relative to the rachis: either horizontal or vertical, as useful in separating L. secundiflorum from L. acutiflorum. I found this character to vary so greatly on single stems that I am sceptical of its usefulness in distinguishing the two species.
Specimens. Harris 449, 1551, 1718.
