Nomenclatural note
Athanasiadis & Ballantine (2024: 33) note "Peña et al. (2021: 473) mechanically selected one (not illustrated) of the original six specimens included in Foslie's (1895a) original account that they considered to be the "narrowed" lectotype but gave no evidence that the relevant specimen is in agreement with the lengthy protologue. The partial psbA and rbcL (bp 263) sequences of the "narrowed" lectotype were identical to the similarly long ones of C. circumscriptum, but fully long sequences (bp 1,172-1,434) of topotypes need to be compared to support this synonymy." - (23 February 2024) - M.D. Guiry
