Delissea undulata (common name ʻoha) is an extremely rare species of "palmoid" or "Corner model tree" (a pachycaulous unbranched tree superficially resembling a palm or cycad) formerly occurring on the Big Island of Hawai'i. It is cited as extinct by the IUCN Red List and Plants of the World Online,[1][3] but is also reported in cultivation from a single surviving plant found in 1992.[4] It is in the subfamily Lobelioideae of the family Campanulaceae. The tree is up to 11 m (36 ft) in height but only 5 cm (2.0 in) in diameter at breast height (DBH). It never branches. The terminal rosette of wavey-edged leaves is only 45 cm (18 in) across. The flowers are tubular and straight.[5]
