“…In fact, in the case of Calandrinia jompomae Hershk. (Hershkovitz, 2020c(Hershkovitz, , 2022b, I pointed out that this species was recognized and characterized twice in the 19 th Century. In one case, an individual specimen (collected in 1832) was annotated as "Calandrinia valdiviana."…”

“…Returning to the tantalizing title of this section, what exactly was "discovered" in the present work? Before addressing this, I want to comment on heuristic approach behind my recent work, here and in Hershkovitz (2018bHershkovitz ( , 2019dHershkovitz ( , 2020c. All of these works began with empirical observations of plants in the field or in the herbarium.…”

“…A similar infrageneric contrast occurs in Calandrinia. In Calandrinia jompomae Hershk., the flowers are oriented laterally, but the distal portion of the pedicel becomes curved vertically upward in fruit (Hershkovitz, 2020c(Hershkovitz, , 2022b. In contrast, in the closely related C. nitida (Ruiz & Pav.)…”

An example is his accurate description of the Type of Calandrinia jompomae Hershk., a Claudio Gay collection (Hershkovitz, 2020c(Hershkovitz, , 2022b. But, based on Candolle's brief protolog, Barnéoud apparently guessed that this plant was Calandrinia glauca Schrad.…”

Cistanthe arenaria (Cham.) Carolin ex Hershk. is a species of Montiaceae distributed from Chile’s Maule to Araucanía Regions. But the name historically and currently has been applied also to readily distinct species distributed from the Libertador Bernardo O’Higgins to Coquimbo Regions: C. chamissoi (Barnéoud) Carolin ex Hershk., C. trigona (Bertero ex Colla) Carolin ex Hershk, C. vicina(Phil.) Carolin ex Hershk., and C. subverticillata (Phil.), ined. (≡ Calandrinia subverticillata Phil.). The source of this confusion traces to two 1833 works by Hooker & Arnott and Lindley. Here, the taxonomy and diagnostic characteristics of these species are clarified.

“…Hershkovitz (2020c) described and discussed a species he called Calandrinia jompomae Hershk. At the time, the name was invalid, because it was not published in a valid journal.Hershkovitz (2022a) published the name and diagnosis again in a valid journal, but the diagnosis was published in Spanish and not English or Latin, as required by ICN Hershkovitz (2022b).…”

Parakeelya Hershk. (Montiaceae) has become the name conserved over the older name Rumicastrum Ulb. for a lineage of Australian plants historically classified in Calandrinia Kunth. In Candollean taxonomy persistent to the late 20th Century, Australian plants were classified in a large, heterogeneous, and polyphyletic circumscription of Calandrinia, later referred to by the designation “Calandrinia s. l.” Following cladistic dissection, Calandrinia “s. str.” was restricted to a small, homogeneous, and well-supported clade of American plants. The Australian plants were referred to the formerly monotypic and poorly studied genus Rumicastrum Ulb., and later to Parakeelya, which specifically excluded the latter. Australian specialists, however, eschewed both of these names and continued to classify existing and new Australian species as Calandrinia. However, they never justified this usage on taxonomic evidence. In some cases, they used the name Calandrinia as though it applied exclusively to the Australian plants, and they never explained why Rumicastrum does or does not pertain to this lineage. Phylogenetics researchers later appropriated the designation “Calandrinia s. l.” to refer to the Australian lineage plus Calandrinia s. str., and predicated to disprove its monophyly, which never was supported in the first place. They demonstrated that Rumicastrum indeed pertains to the Australian lineage, but they proposed nomenclatural conservation of Parakeelya. Yet, in numerous subsequent publications, they continued to use and describe new Australian species in Calandrinia. In the present work, I demonstrate that the application of the name Calandrinia to the Australian species and the designation “Calandrinia s. l.” for this plus Calandrinia s. str. were conceptually illegitimate, because they are conceptual homonyms for the taxa to which these names had been applied. I discuss evidence that this usage was deliberate with the objective of preventing the correct name Rumicastrum from being accepted for the Australian lineage. The evidence includes but is not limited to earlier-reported irregularities in the Australian authors’ proposal to conserve the name Parakeelya, including considerable factually incorrect or otherwise misleading information that biased in favor of the later approved conservation. I discuss this in terms of the equivalence of scientific names to scientific assertions, be they correct or erroneous, and incidentally or deliberately so.
