Cephalotus follicularis

Overview

Kew describes clustered red-green leaves in damp sandy soils near streams and swamps. Hairy pitchers have ridges, a toothed rim and a translucent, striped lid. They contain digestive fluid. Bright green, hairy oval leaves occur alongside the traps; summer flowering stems bear small white flowers.

Fukushima and colleagues sequenced the genome in 2017 and compared transcripts from carnivorous and non-carnivorous leaves. Their analysis identified changes associated with attraction, capture, digestion and nutrient absorption. Comparison with three independently evolved carnivorous plants found repeated recruitment of stress-responsive protein lineages.

Convergent amino-acid changes accompanied digestive physiology. Similar pitcher shapes therefore do not establish close kinship with other pitcher plants. The paper places this species in Cephalotaceae within Oxalidales; its genome results illuminate evolutionary routes, not an illustration’s measured anatomy.

Origins & earliest records

Botanical diagnosis complements genome and digestive-protein comparisons.

Evidence & interpretation

Independent origins make carnivory a case of convergent evolution.
