Diagnosis: One to 2 m understory palms with stem absent or very short, arching pinnate leaves more than 1 m long with 15 - 25 or more slender uniform leaflets per side and held in one plane, inflorescence an erect spike, persistent apical stigma.
Local Distribution: Atlantic slope below 700 m.
Diversity: 1 species (N. watsonii).
Comments: Seen above 700 m elevation in our region only on the Atlantic slope in the drainage of the Rio Esperanza, but occurs higher in some other sites in the Cordillera de Tilaran. The uniform leaflets, unbranched inflorescence and apical residual stigma make this a unique palm in our area.
