Scientific Name:Moronobea pulchra Ducke

Type. In campina arenosa ad Ponta Negro prope Urbem Manaos, civitatis Amazonas capitalem, 1. A. Ducke 20-11-1910 florif. n. 11,200 (Rio). I have seen Ducke 13649 (NY, P, G, Rio), and in addition Coelho 2937 (NY) and Ducke, Manaos, Oct-Nov 1931, s.n. (GH).

A white or pale large flowered form of small stature. Collected on inundable sites near Manaus, Amazonas, Brazil. It is improbable that this population is specifically distinct from M . coccinea, from which it apparently differs only quantitatively. More likely the varzea population constitutes an ecological variant.
