    Hello,

    A question to the taxinomists: do you think barbigerum and coccineum (and others in this group named lockianum...) can be considered as the same unique species or not?

    I'm not a taxonomist, but coccineum and barbigerum even differ in their leaves. While barbigerum leaves are floppy, the leaves of coccineum are stiff and more erect and keeled.

    I have a division of coccineum and the leaves are floppy and plant is much bigger than my barbigerum. plants can be very different in both species.

    My barbigerum leaves are small and stiff. coccinium leaves bigger and floppy.
    barbigerum var vegvarutianum very narrow stiff and succulent. I think they are all different species.

    I don't think you can split them based on the leaves.

    They are all variations of the same thing to my eyes.

    Is a matter of point of view...
    I'll put all them in same specie and give them different varietal names

    Species should be separated on flower morphology and/or genetics, not on leaf size or whether their leaves are rigid or floppy. That is a bit of a variable trait.

    I agree, and of course, the way and place it grows can change the plant habit, less the flowers.
