Description

To 10 m tall; proximal margins of petiole with moderate fibers; leaf blade slightly undulate, divided 2/5-1/2, abaxial surface incompletely covered with scattered lepidia, segment tips drooping to occasionally stiff; inflorescences composed of 1-3 panicles, equaling or exceeding petioles in flower, exceeding petioles or equaling leaf blades in fruit, panicles branched to 2 or 3 orders, rachillae glabrous to clothed with scurfy indumentum in flower, glabrous in fruit or rarely with scurfy indumentum; fruits 35-60 x 30-45 mm, globose to ovoid.

Pritchardia lowreyana is distinctive in its leaf blades incompletely covered abaxially with lepidia, inflorescences equaling to exceeding petioles in flower and exceeding petioles to equaling leaf blades in fruit, glabrous rachillae, and large fruits. On Molokai it occurs with or near P.forbesiana, but the latter differs in its petioles with a greater abundance of fibers proximally and inflorescences shorter than or equal to the petioles. One anomalous collection, Rock 17346 from Waiakapua Valley, Molokai, is rather striking in its fruiting rachillae densely clothed with scurfy indumentum. This well-documented species from Molokai has frequently been identified as or confused with Pritchardia gaudichaudii and P. macrocarpa (see the account of the former under P. martii and the latter in the section on dubious or insufficiently known species for an explanation). In Beccari and Rock (1921), photographs of P. lowreyana are erroneously captioned as P. gaudichaudii ( PI. VIII A, B) and as P. macrocarpa (Pl. XII A, B). Pritchardia lowreyana has long been cultivated in Honolulu, the most famous plant being the tree at Hillebrand's former residence, now Foster Botanical Garden of the Honolulu Botanical Gardens system, and has official designation as an Exceptional Tree of Hawaii (Belknap 1982). The holotype of Pritchardia lowreyana at BISH is unnumbered while the isotype at Fl is numbered Rock 14075. St. John (1984, p. 479) selected one of the syntypes of P. donata (Caum 152) as the lectotype for this binomial. (iucn.org)
