Discussion

  • Pritchardia arecina is distinguished by its petioles with an abundance of fibers proximally, leaf blades completely covered abaxially with lepidia, and large fruits. It is I similar to the highly variable P. martii, but the latter differs in its petioles with irregularly shaped, papery ligules or wings or only a few fibers proximally. It is also somewhat similar to P. woodii, which occurs not too far to the southwest in East Maui but in slightly drier areas; P. wDodii, however, differs in its leaf blades incompletely covered abaxially with lepidia and petioles with only a few fibers proximally. (Hodel, D. 2007. A Review of the Genus Pritchardia. Palms 51(4): Special Supplement S 1-53.)A

Description

  • To 15 m tall, emergent; proximal margins of petiole with moderate to abundant fibers; leaf blade slightly undulate to nearly flat, divided 1/4-1/3, abaxial surface completely covered with lepidia and appearing silvery grayish while to somewhat reddish brown, segment tips stiff; inflorescences composed of 1 or 2 panicles, equaling to exceeding petioles in flower, exceeding petioles or equaling leaf blades in fruit, panicles branched to 2 orders, rachillae permanently clothed with dense, felt-like to nearly woolly indumentum; fruits 45 x 38-40 mm, ellipsoid.
