Just catching up on the Logs after a holiday.
The crocus in the final picture looks like it is Crocus nudiflorus, no need for a '?' The long tube, prominent cataphylls and overall appearance all strongly suggest Crocus nudiflorus. The only other candidate would be one of the Crocus serotinus clan but the long tube (especially in relation to flower size/shape) and the complete absence of leaves make this unlikely.
Repotting under way here at last. Autumn crocus mostly OK, losses come in the greenhouse (no warming cable) and a few around the edges of a 'glass over' frame where pots were wettest. In the access frame (closed sides as well as glass overhead) almost no losses and some showing better increase than normal!
