Leaves
pinnae 4(3–7) per side of rachis.
Inflorescences
rachillae 4(2–6), 5.1(3.8–6.5) mm in diameter, not hairy, not filiform and not narrowed between the flower pits; proximal and distal lips drying the same color as the rachillae; triads mostly spirally arranged.
Distribution and habitat:—
From 14°09’–
15°18’S
and 39°00’–
39°16’W
in the Atlantic Coastal Forest of
Brazil
in central
Bahia
at 212(45–380) m elevation in lowland tropical rainforest (
Fig. 35
).
Labels of some specimens (e.g.,
Carvalho 6775, Noblick 4726
) describe the stems, leaves, and inflorescences as reddish-tinged. Some specimens (e.g.,
Fiaschi 1051
), sympatric with
subsp.
unaensis
, exactly resemble that subspecies except for the non-hairy rachillae. The differences between the two subspecies are not clear.
