Delissea subcordata
species of plant
Delissea subcordata is a rare species of flowering plant in the family Campanulaceae known by the common names Koʻolau Range delissea and oha. It is endemic to Hawaii, where it is known only from the island of Oahu. It is now only found in the Waianae Mountains, and it is believed to be extirpated from the Koʻolau Range, where it once occurred. As of 2008 there were 40 individuals remaining, 28 of which were mature plants. This plant was federally listed as an endangered species of the United States in 1996.
This Hawaiian lobelioid is a shrub which grows up to 3 meters tall and bears white or greenish flowers. It grows in moist forest habitat. Other plants in the forests include ohia lehua (Metrosideros polymorpha) and koa (Acacia koa), which dominate the canopy, and Ēlama (Diospyros hillebrandii), papala kepau (Pisonia spp.), and ʻĀlaʻa (Planchonella sandwicensis) in the understory.
Threats to this rare species and its ecosystem include feral goats and pigs.

Why this record matters
“Delissea subcordata” is worth following because a concise public description often conceals a longer documentary argument. Here, Delissea, subcordata and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 12, 2026. The linked authority identifier is Q5254027. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008 and 1996.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
