Pritchardia viscosa, the stickybud pritchardia{{PLANTS|id=PRVI2|taxon=Pritchardia viscosa|accessdate=14 October 2015}} or lo{{okina}}ulu, is an extremely rare endangered species of Pritchardia palm that is endemic to the Hawaiian island of Kaua{{okina}}i.{{cite web |url=http://www.centerforplantconservation.org/Collection/CPC_ViewProfile.asp?CPCNum=12967 |title=Pritchardia viscosa |website=CPC National Collection Plant Profiles |publisher=Center for Plant Conservation |access-date=2009-11-12 |url-status=dead |archive-url=https://web.archive.org/web/20101027160144/http://centerforplantconservation.org/Collection/CPC_ViewProfile.asp?CPCNum=12967 |archive-date=2010-10-27 }}

It inhabits open wet forests in the Kalihiwai Valley, where it grows at altitudes of {{convert|500|-|700|m|ft|abbr=on}}. Associated plants include {{okina}}aiea (Ilex anomala), {{okina}}ahakea (Bobea spp.), hame, (Antidesma spp.), hāpu{{okina}}u pulu (Cibotium glacum), and kōpiko (Psychotria hexandra).

It is a medium-sized palm from {{convert|6|-|8|m|ft|abbr=on}} tall, with palmate (fan-shaped) leaves about {{convert|1|m|ft|abbr=on}} long. The fruit is produced in dense clusters, each fruit green, pear-shaped, {{convert|4|cm|in|abbr=on}} long and {{convert|2.5|cm|in|abbr=on}} in diameter.

Like the related Nihoa Fan Palm (P. remota), it is susceptible to extinction by a single catastrophic event because of its wild population of four individuals. It is threatened by introduced rats, which eat the seeds. It has been cultivated to a moderate extent, but is exceptionally limited in its habitat.
