General comments:
Immigrant.

There is no evidence at all to suggest that the Dark Sword-grass breeds in Hertfordshire and it is probable that all records relate to primary immigrants from overseas. It is recorded in plenty in most years.

Recorded in 36 (88%) of 41 10k Squares.
First Recorded in 1887.
Last Recorded in 2023.
