Boyce, P. C. & S. Y. Wong Lost Aroids: On the taxonomic importance of relocating poorly collected species

Figure 4. Aridarum nicolsonii Bogner, is endemic to and abundant on Santubong (A) and near-by Bako. It differs from A. montanum by, among other characters: (B) the much larger inflorescences; (C) the much shorter thecae horns; and (D) by the considerably broader leaf blades, and proportionately longer petioles. Overall A. nicolsonii is also a much larger and more robust plant than A. montanum. Scale bars: B=2cm; C=5mm; D=2cm. Images © Peter C. Boyce.
