Oldenlandia adscensionis
Oldenlandia adscensionis fuit species plantarum florentium familiae Rubiacearum, in Insula Ascensionis endemica. Exstincta facta est ob detrimentum habitationis. Ea in septentrionalibus occiduisque Montis Viridis declivitatibus inter 356 m et 680 m olim inventa est, sed postquam Gordon eam anno 1889 eam repperit non visa est (Cronk 1980). Observatio anno 1985 facta (Cronk 2000) manet non confirmata, quia specimen non conlectum vel photographatum est.
