When I've bothered to look, I have found that no cotyledons appear for
Drosophyllum seedlings. The seedcoat is retained by two very short
projections (cotyledons that never shed the seedcoat?) that attach at
right angles to the main plant, which is stem and leaves above
and root below.

FWIW, I have read that the same occurs for tuberous drosera: ie if the
seedling has cotyledons it is not a tuberous drosera.
