Whitebeams, 'microspecies', or 'full' species, several the population is tens or low hundreds of individual plants. True Service-tree (Sorbus domestica) Porthkerry, we were able to confirm statistically that the 14 ramets that were sampled are very likely to belong to only one genet. A rare tree.
🌳 Britain's rarest native timber tree might surprise you! The true native Black Poplar, Populus nigra, has only ~7,000 wild specimens left – and just ~600 are female.

We're chuffed to bits to see this 'monumental propagation effort' increase the population of the extremely rare Catacol whitebeam (not found anywhere else in the world). Well done @n-t-s.bsky.social & In Vitro Microplants. www.heraldscotland.com/news/2659402...

Just received my brand new Whitebeams, Rowans and Service Trees @bsbibotany.bsky.social book - it looks really good. I am surprised that everything is still called Sorbus. I thought that genus had been officially split up? I renamed all my old photos! (Hedlundia, Aria, etc......)

In Fitzgerald's Road,#Lewes, this morning to weed and mulch the seven #trees we planted there in 2022 - an Amelanchier, a Judas Tree, three Alders and two Whitebeams. Then round the corner to Queen's Road to look after the three Field Maples we planted there. Hot work!

This year I've finally bitten the bullet and begun looking at whitebeams. Earlier this week it was the turn of the Menai Strait Whitebeam (Sorbus arvonicola) - easily separated from Sorbus aria at the same site by the grey leaf undersides (comparison in the last photo). @bsbibotany.bsky.social
