Look like one of the Colchicums to me.

Recently I unpotted one of my community pots. I have a number of raised
beds with large pots of bulbs in containers that nest in containers with
the medium between them a mix of sand and gravel. I don't repot them
every year unless when I pull them out in summer it is clear they are
full of redwood roots that have made their way in through the drainage
holes. This pot I hadn't repotted for years. When I repot I sometimes
find what I originally planted is gone, dwindled or sometimes increased
dramatically, but also find some items that are not on my tags for that
pot. This time I found a whole lot of different sized tubers. They look
a bit like Gloriosa tubers to me (maybe modesta?) Nothing faintly
resembling those leaves had ever appeared in that pot to my knowledge,
but my raised beds are dry in summer and rained on in winter, not at all
like Gloriosa tubers I have in my greenhouse that are dry in winter and
I start watering late spring and continue watering through the summer. I
suppose some  seed could have made its way into the pot and had years to
develop and if so tolerated winter rainfall, sometimes a lot of it
(although those pesky redwood roots do soak up the moisture). I'm happy
to send them to Albert for the BX in case anyone wants to experiment
with them, but it would be nice to know their identity. I attach a photo.
