Chirita devine Genul Primulina

  • Recent au fost efectuate unele modificari in genul Chirita.
    Cea mai importanta modificare este denumirea, Chirita devine Primulina.
    Alte modificari includ transferarea unor subgenuri in alt gen.

    Chirita era impartita pana acum in 3 grupuri:
    sectiunea Chirita (Sri Lanka, India si Himalaya - tufe sau specii non-suculente)
    sectionea Microchirita (specii rozete anuale tropicale, Asia de Sud-Est)
    sectiunea Gibbosaccus (specii cu frunze carnoase - China de Sud si Vietnamul de Nord).

    Chirita asperifolia si alte specii inrudite ale acesteia (specii tufe tropicale din Sumatra si Java) au fost recent separate intr-o noua sectiune, a patra cu denumirea Liebigia. Acestea s-au dovedit a fi mai apropiate altor genuri.

    Dupa reclasificarile survenite, aceste specii sunt plasate astfel:

    Sectiunea Liebigia: aceste specii devin genul Liebigia.

    Sectiunea Microchirita
    : acestea devin acum genul Microchirita.

    Sectiunea Gibbosaccus: aceste specii devin acum genul Primulina. Acest gen include de asemenea si specii ale fostului gen Chiritopsis. Alaturi de Primulina tabacum si alte specii Chiritopsis, precum Gibbosaccus. Iar pentru ca Primulina este numele generic mai vechi in aceasta clasificare, genul devine Primulina.
    Cea mai mare dificultate o prezinta modificarea numelui speciei Chirita sinensis, care acum devine Primulina dryas (pentru Primulina sinensis deja exista in cadrul genului).

    Sectiunea Chirita: acesta sectiune include tipurile de specii de Chirita (C. urticifolia), ia r majoritatea speciilor sunt incluse in grupul care contine si tipurile de specii de Hneckelia (H. incana din India de Sud). Si pentru ca Henckelia este un nume mai vechi decat Chirita, acesta are prioritate si aceste specii devin Henckelia.
    Astfel, denumirea de Chirita dispare.

    Mai pe scurt, Chiritele pe care le avem noi in Romania, devin Primuline toate.

    Unele explicatii le gasiti si pe Site-ul Societatii Europene de Violetelor Africane:

    Chirita has traditionally been subdivided into 3 groups of species: section Chirita (mostly Sri Lankan, Indian, and Himalayan, shrubby or annual non-succulent species), section Microchirita (tropical annual species, mostly from SE Asia), and section Gibbosaccus (fleshy-leafed rosulate species from southern China and northern Vietnam). Chirita asperifolia and its immediate relatives (all tropical, shrubby species from Sumatra and Java) were more recently split off into a fourth section, Liebigia. These various groups turn out not to be closely related to each other, and more closely related to other genera. Here's a quick summary of where these species are now placed:

    Section Liebigia: these species now become the genus Liebigia.

    Section Microchirita: these now become the genus Microchirita.

    Section Gibbosaccus: these species now become the genus Primulina. This genus now also includes the species formerly in Chiritopsis. Primulina tabacum and all the Chiritopsis species fall smack in the middle of section Gibbosaccus, and Primulina is the oldest available generic name within this group. The biggest problem here is that Chirita sinensis now becomes Primulina dryas (because the name Primulina sinensis already existed).

    Section Chirita: this section includes the type species of Chirita (C. urticifolia), and most of these species fell into a group that included the type species of Henckelia (H. incana from southern India). Since Henckelia is an older name than Chirita, it takes priority and these species become Henckelia. *Poof*, Chirita is gone.

    Meanwhile, the non-Indian species of Henckelia prove to belong somewhere else entirely, and will presumably be transferred to one or more other genera in the near future.

    The biggest practical effect for hobbyists is that most of the familiar species of Chirita (i.e., the rosulate species from China and their hybrids) will now become Primulina. And let's face it, that's not such a bad name for them.

    In numarul de septembrie-octombrie al revistei African violet Society of America, de asemenea, este mentionata modificarea. Atasez articolul.
