51g. Geonoma pohliana subsp. rubescens (Wendland ex Drude) Henderson , comb. & stat. nov.

Basionym: Geonoma rubescens Wendland ex Drude (1882: 491) . Type: BRAZIL. Bahia: Ilhéus, no date, J. Blanchet s.n. (holotype BR!, isotype P!).

Geonoma platycaula Drude & Trial in Drude (1882: 490) . Type: BRAZIL. Bahia: without locality, no date, C. Martius s.n. (holotype M!).

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.
