NOTE. — The
neotype
that has been designated does not fit the original description of
T. liberica
in all aspects. The number of lateral nerves for instance are
4-6 in
the original diagnosis, much lower than in the specimens assigned to this species in this publication. Analysis of ENGLER’ s description reveals that his mention of 4-6 veins must be too low. He described the size of the leaflets as 10-15 ×
5-6 cm
, and the nerves as being
1-1.5 cm
apart. Based on these data the number of main laterals must therefore have been higher than 4-6 pairs. The second notable difference is seen in the male flowers, which ENGLER described as sessile whereas in the
neotype
the flowers have a pedicel of
1-1.5 mm
. This difference may be of little importance as, at least in some species (e.g.
T. lucens
), this element varies to the same degree.
