ID: 024

Date: 28 May 2024

Locality: The Taxiway, Weston-super-Mare

Location (Lat/Long): 51.344, -2.935

Landscape/habitat: At the side of a disused road/taxiway. Near some industrial units, wasteland.

Identification notes: Leaves looked crinkly/curled at the edges. There were quite a few holes in the leaves where something had eaten it, so it looked a little worse for wear. Possibly the red weevil (see photo).

From Streeter et al. (2016, p.152) description of characters, with my observations:

  • 'Basal leaves narrow' and leaf 'edges strongly undulate or crisped' - this is one of the key characters, we can see from the photos that the edges of the leaves are very curled/undulated.

  • Habitat of 'waste places, roadsides...' (as shown in photos)

  • There are a number of sub-species. ssp. littoreus flowers with a dense inflorescence, and can also be found on coastal shingle, sand-dunes. From this description I may hazard that it could be this subspecies as the inflorescence looks like it would be dense to me, and the location is fairly coastal.
