Discussion

  • Pritchardia waialealeana is difficult to distinguish from P. glabrata and P. remota. All three share the undulate leaf blades incompletely covered abaxially with lepidia and with drooping segment tips, inflorescences shorter than or equaling the petioles with panicles branched to three orders, glabrous rachillae, and small fruits. However, both P. glabrata and P. remota differ in the folds on the abaxial surface of their leaf blades clothed with thick, cottony or mealy indumentum and the more or less rounded fruits. A search failed to reveal any of Read's designated type material (Read 87-211) at US, BISH, HLA (HAW), BH, or PTBG; thus, I have designated Lorence 8446 from the type locality as the neotype. A photograph of Pritchardia waialealeana is erroneously captioned P. hardy; in Beccari and Rock (1921, PI. XIII A). (Hodel, D. 2007. A Review of the Genus Pritchardia.
