TABLE 2. Morphological differences between the new species E. manausensis and E. banaensis G.A. Romero & Aymard, E. bijuga Bentham (1870: 226), E. grandiflora subsp. grandiflora , E. grandiflora subsp. guyanensis , E. jenmanii Oliver (1891: 20), E. obtusata R.S. Cowan (1975: 33), E. oleifera Ducke (1932: 728), and E. purpurea Bentham (1870: 226), which E. manausensis shares short and erect inflorescences, tubular corollas, and inserted stamens. The indumentum is considered scarce when it is puberulous (E. bijuga, E. jenmanii) or strigulose (E. banaensis, E. obtusata), and dense when it is tomentose (E. manausensis, E. grandiflora subsp. grandiflora, E. oleifera), pubescent (E. grandiflora subsp. guyanensis , E. grandiflora subsp. grandiflora), or strigose (E. oleifera).
