Missing Vascular Plants

Trying to compose list for a south coast nature reserve. These seem to be missing:
Sea Beet Beta maritima
Salsify hybrid Tragopogon x mirabilis
Its a struggle, but worth it in the end!

Hi Peter -  sorry for the delay in replying.
1) Sea Beet is Beta vulgaris (var maritima) so it doesn't get a separate entry.
2) The hybrid Tragopogon wasn't one that we selected as a particularly stable hybrid, i.e. it doesn't have a separate numbered entry in Stace. We've stuck to those for starters rather than allowing in every possible plant hybrid.
Cheers
Andy
