Discussion

  • I could find no reliable characters to separate Pritchardia glabrata from P. eiliptica and P. lanaiensisi thus, with the inclusion of these in synonymy, P. glabrata is another of the four Hawaiian species that is recorded from more than one island. Pritchardia glabrata is difficult to distinguish from P. remota and P. waialealeana. 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. Both the latter species, however, differ in their generally larger habit. Also, P. remota differs in its slightly waxy glaucous leaf blades while P. waialealeana differs in the lack of cottony hairs or mealy indumentum on the abaxial folds of its leaf blades and the longer-than-wide fruits. The holotype of Pritchardia lanaiensis at FI is unnumbered while the isotype at BISH has a Rock number, probably one that Rock added later to Munro's specimen. Rock not infrequently added his or some other number (perhaps a number from a herbarium numbering system) to other collectors' material. (Hodel, D. 2007. A Review of the Genus Pritchardia.

Description

  • To 5 m tall; proximal margins of petiole with only a few fibers; leaf blade undulate, divided 1/2, abaxial surface incompletely covered with scattered lepidia, segment tips stiff to drooping; inflorescences composed of 1-3 panicles, shorter than or equaling petioles in flower and fruit, panicles branched to 2 or 3 orders, rachillae glabrous; fruits 20-30 x 20-2S mm, globose to ellipsoid.
