cens in the branched inflorescence, the stomatal
cavities and the leaf shape. It differs from C.
racemosa in the much smaller, blunt leaves, the
deep well-defined stomatal cavities, the shorter
petioles and the lanate pubescence of the leaf
venation below.
It is with pleasure that this species is dedicated
to Ieda L. do Amaral, the Brazilian botanist who
was leader of the Araca expedition on which the
type was collected.
6-32. Couepia insignis Fritsch, Ann. K. K. Na-
turhist. Hofmus. 5: 11. 1890. Fig. 106.
This distinctive species was described from
scant material, all from Bahia, Brazil but without
precise locality, in Prance (1972). The nineteenth
century material is now complemented by two
recent collections indicating that this species still
survives in the coastal forest.

This species is closest to Couepia insignis, C.
martinii, and C. bondarii. It differs from all three
in the tomentose interior of the receptacle, an
uncommon feature in the genus, occurring in only
one other species with a racemose inflorescence,
the Andean C. recurva, which is otherwise very
different. Couepia cidiana also differs from its
three closest relatives in the much longer flowers,
the persistent and longer stipules and the large
number (26-35) of primary leaf veins.

Distribution (Fig. 114). This species was de-
scribed from a single Spruce collection from Ec-
uador without locality. A second collection from
the Ecuadorean Andes has now been examined.
