Pritchardia woodii Hodel

First published in Palms (1999+) 51(Suppl.): S-44 (2007)
This species is accepted
The native range of this species is Hawaiian Islands (E. Maui). It is a tree and grows primarily in the wet tropical biome.


Associated genera include Cheirodendron, Labordia, Machaerina and Perrottetia.
P. lanigerae affinis sed rhachillis et rhachidibus velutinis differt.
Potential threats include invasive plant species such as Clidemia hirta and Rubus rosifolius and pigs and rats. The conservation status of P. woodii is probably best considered endangered because of the small number of mature palms and the threats to their survival. It is cultivated at Hoomaluhia and Wahiawa Botanical Gardens of the Honolulu Botanical Gardens system on Oahu.

Inflorescences 5-7 interfoliar, 75-135 cm long, erect and shorter than or equaling petioles in flower, arching or nodding and exceeding petioles but shorter than leaf blades in fruit, composed of 1 or 2 long axes each terminating in a compact panicle; axes 65-120 cm long, slender, 1.8-3 em wide and 1.1 cm thick at base with prophyll, 1-2 cm wide at apex and flattened, densely covered with grayish brown, short, velvety hairs under bracts; prophyll 25 x 7.5 cm, marescent at tip, flattened and bicarinate at base, 7-8 peduncular bracts, these 15-40 cm long, longest proximally, shortest distally, tightly sheathing proximally, expanded and boat-like distally, papery, brown, uppermost extending onto and partially concealing panicle, all bracts with scurfy, deciduous indumentum; panicle densely branched to 2 orders, 15-22 cm long, rachis 10-15 em long, proximal branches with sub-peduncle to 2.5 em long, sub-rachis 1.5 em long, and with 5-8 rachillae, distal branches simple rachillae, 20-25 rachillae total, rachillae 8-13 em long, 2 mm diam. in flower, 3-3.5 mm diam. in fruit, stiff, strongly flexuose, narrowly diverging (45 degrees or less) from rachis, densely covered in flower and fruit with short, velvety hairs, these white to grayish in flower, brownish in fruit. Flowers densely placed in 1 or 2 spiralling rows 3-5 mm apart, flowers 2 or 3 mm apart within a row, very strongly slanted or disposed distally, sometimes nearly reclining, in prominent clefts 1.5 mm deep, each cleft with a filamentous bracteole 4 or 5 mm long subtending the flower proximally; flowers at anthesis 9-10 x 7-10 mm, greenish yellow; calyx 5 mm high, coriaceous, greenish proximally, yellowish green distally, sepals imbricate at apex, mucronate; corolla tube about equaling calyx, lobes 6 x 3 mm, lanceolate, acute, light yellowish, prominently nerved adaxially, faintly nerved abaxially; staminal tube amber to brownish, exserted 1 mm above calyx, stamens spreading, borne on filaments 1 or 2 mm long, anthers 4 mm long, oblong, medifixed dorsally about 1/3 from their base, spreading flat; pistil 6-7 x 2 or 3 mm, spindle-shaped, ovary 2.5 x 2 mm, style 3.0-3.5 mm long, yellowish, exserted 2 or 3 mm above staminal ring, columnar, truncate apically.
