Not to be outdone, eleven Leicestershire botanists donned hard hats, hi-vis jackets, steel toe-capped boots and safety goggles last Saturday to record the plants at British Gypsum's Barrow Works.
The introductory Health & Safety talk - essential when touring an active industrial site - was considerably sweetened by the Kit-Kats handed out by our host, Luke Menzel, the plant's Environmental Co-ordinator.

Once kitted up, we headed out to start recording and - typical botanists - it took us almost an hour to get more than 100m from the car park!
The first two verges we came to were very rich, with plants typical of old mesotrophic and calcareous grassland.
These included Lathyrus nissolia (Grass vetchling), Catapodium rigidum (Fern-grass), Leontodon hispidus (Rough Hawkbit), Centaurium erythraea (Common centaury), Bromus secalinus (Rye brome), Hordeum secalinum (Meadow Barley), Centaurea scabiosa (Greater knapweed), Knautia arvensis (Field scabious), Pilosella officinarum (Mouse-ear hawkweed), Plantago media (Hoary plantain), Arenaria serpyllifolia (Thyme-leaved sandwort), Trisetum flavescens (Yellow oat-grass)...

An adjacent ditch yielded a charophyte (probably Chara vulgata but the specimen is still being checked) and a rose with conspicuous gland-tipped red hairs which keyed out as Rosa micrantha using Roger Maskew's key.
Luke borrowed a hand-lens to examine those hairs and had to admit that yes, they were pretty impressive!
Another notable find was Sison amomum (Stone parsley), an unassuming little plant but scarce enough in Leicestershire and Rutland (VC55) to be listed on the county’s Rare Plant Register.

A specimen was taken on the same verge of what appeared to be Crepis biennis (Rough hawk's-beard), another RPR species so this one is also being checked.
Then on to a pond and another ditch where it was time to get the grapnels out for Apium nodiflorum (Fool's water-cress) growing - as though ironically - next to Nasturtium officinale (genuine Water-cress)!

All these plants are unusual enough in VC55 to elicit a few squeals of delight whenever you see them!
We also found what we think is Euphorbia stricta (Upright Spurge). It would be the first 21st century record for this plant in Leicestershire so again, it's being checked carefully.

Huge thanks to British Gypsum for hosting us and especially to Luke who looked after us so well all day.
But back to those Kit-Kats - do they really contain gypsum?
Answers on a postcard please....
