Notes.
– This species was described from New
Guinea
, and this name was lectotypified by
SOHMER (1988)
even though he considered its identity too unclear to include it in his formal treatment. The
holotype
specimen was deposited at B, and has been destroyed. The
lectotype
is the only authentic material of
Psychotria polita
known, and has only very young inflorescences so its identity cannot be determined easily.
SOHMER (1988)
suggested that
P. polita
might be the same as
P. rostrata
Blume
from Java, another species of uncertain identity. The type specimen of
P. polita
does have the yellowish green drying color and hard fragmented stipules of
Eumachia
, but the identity of this name is otherwise unclear so it is not recognized as a species of
Eumachia
here.
