Elleanthus natural senescence habit

[qbie]

Hello it's me again

I picked up an Elleanthus last year which is possibly amethystinus and was wondering, after flowering, are those canes, unlike Dendrobium kingianum, incapable of flowering again in subsequent seasons? If so, do the leaves on those canes naturally brown later that year or a subsequent year after flowering? I can't seem to find much information about Elleanthus in general. Thanks.
