Glaux maritima (Sea Milkwort) dominant on a sixhalophyte road verge in South Northumberland JOHN RICHARDS
G
laux maritima (Sea Milkwort), common and widespread in maritime locations, has been recorded in very few inland locations on salted road verges. As far as I can ascertain from the BSBI maps website (database.bsbi.org/maps), it has only been recorded in nine hectads away from tidal influence: six in the West Midlands, one in eastern Scotland (NO17), one on Hartside Summit in Cumbria (NY64) and two in South Northumberland. The record for NY47 should be for SD47 which is coastal. One of the Northumberland records I made myself
while listing plants in NY9853 (Winnowshill, v.c. 67) on 26 July, 2010. My recollection is that only a few isolated plants were present. In August 2021 Jim Bowyer reported large quantities of Glaux maritima growing in what is presumably the same site, at NY 9825 5378, in company with Plantago coronopus (Buck’s-horn Plantain) first recorded from here in 2003, but which I failed to record in 2010. I visited this location on 30 August 2021. Glaux and P. coronopus both now occur in great quantities over some 700 m distance on both BSBI NEWS 149 | January 2022
