Hepaticophyta

Summmary as given in Stotler & Crandall-Stotler, 2008.

The divisional name Hepatophyta Stotler & Crand.-Stotl., 1977, was intended to be typified by the genus Hepatica Adans. non Mill. This name has two problems: (1) It is incorrectly formed (orth. err.) and should have been spelled Hepaticophyta. (2) The genus Hepatica Adans. non Mill. is an illegitimate generic name, and homonym of an earlier name.

This latter problem means that Hepatophyta was not validly published under Art. 16.1 / 32.1(c) of the ICBN, and that names of any rank using "Hepatic-" cannot be published. The name Hepaticae is an exception; it is a descriptive name without rank, and is used explicitly as a descriptive name in Art. 13.1(c) of the 2017 edition of the ICN.

The emended spelling Hepaticophyta Stotler et Crand.-Stotl. was published in 2000, but this name is also unacceptable because it relies on the 1977 publication based on the illegitimate generic name.

The correct divisional name is Marchantiophyta Stotler & Crand.-Stotl. in A.J.Shaw & Goffinet, Bryoph. Biol. 54, 63. 2000

Jungermanniophyta

Jungermanniophyta does not seem to have ever been published in accordance with the ICN. The majority of its usage can be traced to publications on Brazilian liverworts by C.J.P. Bastos & S.B. Vilas Bôas-Bastos. --EncycloPetey (talk) 21:01, 17 May 2020 (UTC)
