The Terpsichorean Syndrome in Grammitid Ferns
A personal highlight for me during field work in Papua New Guinea this year was finding Tomophyllum beleense (Fig. A). These plants have thin membranaceous laminae covered in long hairs. They are confined to relatively dry, protected areas, usually beneath limbs or trunks of large trees. They show remarkable similarity to the Neotropical genus Alansmia (Fig. B), which has similar morphology and is found in the same habitat niche.
