hallo Vinc,
aha - und was sagt mir das?
Das es doch zwei verschiedene Arten gibt/sind?

Hallo Dieter,
sorry, war gerade aus zeitlichen Gründen bisschen kurz angebunden.
Die Autoren betrachten T. brasiliensis var. brasiliensis und T. brasiliensis var. acanthocoma als zwei Unterarten, da sie sich einerseits zu ähnlich sind, um als zwei eigenständige Arten zu gelten, zugleich aber zu unterschiedlich, um als eine gemeinsame Art zusammengefasst zu werden.

Unterschiede nach Cano et al. (2013) sind:
Trithrinax brasiliensis var. brasiliensis: Vorkommen: Südbrasilien, Southern Rio Grande do Sul 200 - 400 m.ü.M; Stammhöhe 1-6m; Blatt blassgrün, dünn; Blattsegmente elastisch, nicht verholzt; Anzahl Blattsegmente ca. 34.
Trithrinax brasiliensis var. acanthocoma: Vorkommen: Südbrasilien, Northern Rio Grande do Sul und Paraguay, 450 - 950 m.ü.M; Stammhöhe 2-15m; Blatt dunkelgrün, dick; Blattsegmente steif, verholzt; Anzahl Blattsegmente ca. 41.

Liebe Grüsse,
Vincent

Hier noch die ganze Geschichte mit dem hin und her der beiden (Unter-)Arten aus Cano et al. (2013):
"Trithrinax brasiliensis was the first species described for the genus on the base of a collection made by Sellow in the southern Brazilian state of Rio Grande do Sul (RS). In 1878, Drude described Trithrinax acanthocoma, based on a personal communication by Glaziou, who showed him this ornamental palm cultivated in Rio de Janeiro and in some European parks and for which natural populations were reported to be distributed in southern Brazil. Drude did not designate a type specimen in his publication; however, in his treatment of the palms for the Flora Brasiliensis (Drude 1882) he complemented the description of T. acanthocoma and designated as type specimen a collection of Glaziou (9014, P). The definition of these two taxa has been controversial and they have been treated in different ways throughout history. Mattos (1977) described the palms of the Brazilian state of Rio Grande do Sul, and presented a new combination for Trithrinax acanthocoma, placing the taxon as a variety of T. brasiliensis. Unfortunately, this important publication has not been cited in the most recent publications dealing with the genus Trithrinax. In 1995, Henderson et al. placed T. acanthocoma as a synonym of T. brasiliensis and the most updated treatment of Brazilian palms by Lorenzi et al. (2010) reopened the debate by recognizing both names as independent specific entities. To clarify this situation, we visited the natural populations of both taxa, we analysed herbarium specimens, and we applied molecular phylogenetic methods (Cano et al. unpublished). The resulting phylogeny lacked resolution at the specific and infraspecific levels (Cano et al. unpublished), hindering any taxonomic decision. However, the morphological analysis of the specimens and fieldwork revealed several differences between them, especially regarding the vegetative morphology (Tab. 1, key to the varieties of the species), and contrasting distribution patterns between the two taxa (Fig. 6). Consequently, we adopt Mattos’ (1977) decision and recognise two varieties within the species: Trithrinax brasiliensis var. brasiliensis and T. brasiliensis var. acanthocoma."

Hallo Vincent,
danke für die (wahrscheinlich) ausführliche Erklärung in Englisch....
...aber gibt es die auch in Deutsch?

@Dieter
Jage es doch einfach durch den google-Übersetzer

@Vinc
Danke für die ausführliche Beschreibung
Schon interessant, das die beiden varietäten, welche sich insbesondere durch die Größe enorm unterscheiden, zu einer Art gezählt werden.
