Without dimesnions and a flower...........
My guess - A. polyphylla. Maximum bulb dimensions maybe 15mm diameter and 15mm long, but retains lots of tunics.
A winter-grower but just about stays evergreen. It flowers late spring.
Very tall flowering spike, for the size of bulb, and a gorgeous scent.
Offsets freely.
If it is A. p., keep totally dry late April to August in the UK/Europe.
It gets various names, inc. A. sp. Namibia.
Unlikely to be hardy, 5C minimum probably, to be safe.
