Cyphostemma segmentatum seed advice?

It is a geophyte, and the seeds need no special treatment except a year or so of aging and planting at the right time.

Is it not? There's some kind of underground structure there, though I
don't know botanically what sort. It's always grown with just the neck
of the tuber (or whatever it is) and the deciduous foliage above ground
for me, never as a caudiciform, so I just assumed it was within the
mandate. But if it's not appropriate here then sorry, and I'll ask that
any replies be sent to me personally.


>> Internet comments are consistent in using words like "erratic" and "difficult" about germination, but then range from "most will germinate ... eventually" to "sow in vitro". I can do in vitro if it's necessary, or more accurately my wife, who flasks all our orchid seed, can, but ... does anyone know if it really is? And if so, have any advice on the protocols (seed sterilization, medium, nutrient levels, etc. etc.)?
