In his Carnivorous Plant Database, taxonomist Jan Schlauer treats N. gantungensis, N. leonardoi and N. mira as heterotypic synonyms of N. deaniana.[4]
Adolph Daniel Edward Elmer recorded a plant from Mount Pulgar (now known as Thumb Peak) matching the description of N. deaniana. He made mention of this discovery in the April 20, 1912 issue of Leaflets of Philippine Botany, in his formal description of N. graciliflora:[5]
Recently the writer [Elmer] observed a large sterile species on mount Pulgar of Palawan. Some of its pitchers were a foot long and six inches thick!
