@TamsinQuinn1 Hi Tamsin, wait for the flowers to come out as the open capitulum has lots of key characters to aid ID.

@BirdingCalvert I need a copy. These are just two of the varieties on my allotment.

I've published my book Britain's Dandelions, A Photographic Guide. It's currently available on Blurb blurb.co.uk/b/12805510-bri… Next week I will be adding additional selling sites. #Taraxacum #Botany #Dandelions #BritainsDandelions

@astrid_biddle @wildflower_hour @BSBIbotany It really does take over. Still not found it in Oxfordshire VC23.

Chalk grassland botany today. The Bourne End Junction on the A41, Herts. Common Spotted-orchid (Dactylorhiza fuchsii) for @wildflower_hour with the Hawkweed, Hieracium grandidens, going for World domination.

@botany_beck Your hawkweed looks like Hieracium grandidens vascularplants.co.uk/product-page/1…

Posting a little early as I’m currently on the ferry from Aberdeen to Kirkwall. So excited to be visiting Orkney😀 We had a pitstop at Stirling Castle & it was lovely to see lots of Fairy Foxglove, Erinus alpinus & this mystery Hawkweed for #WildflowerHour, amazing views too!

@AxeBirder @GriffinWildlife Agreed

@GriffinWildlife Presumably this is not one of them? Looks like a Little Grebe to me

Unreal! Found a 1st for Oman!!! 2 Red-necked Grebes at Quriyat Salt Pans this morning. 👌👍

@Alexis434Alexis @wordwellbooks @MonaghanCoCo @NPWSIreland Going to have to get this. Especially as it has #Taraxacum inclinorum on the front cover.

After almost 10 years of work, my first book has finally arrived, Flora of County Monaghan, published by Wordwell - with 310+ colour images and 7 intro chapters, there are over 1,200 species accounts included, all about the many plants that make or have made Monaghan their home

@LeeEvansBirding @stuartjread Saw lots up there earlier this year at the end of June

@stuartjread Any Mountain Ringlets?

Ben Lawers last week, photo from summit plus Alpine & Drooping Saxifrage from the crags at the top

@stuartjread Intrepid botany 👍

@_Stickybeak Ah yes, thanks lots more updates to come this year😁

@BirdingCalvert Clasping stem leaves took us to section cerinthoidea, and much better botanists than us have agreed with H. anglicum, but we're new to these and glad to hear any thoughts. Love all the Hieracium on your website!

This month we've been searching for hawkweeds on Rathlin - invariably hard to reach in awkward crevices on the basalt cliffs and camouflaged by the abundant Cat's-ear! This seems to be Hieracium anglicum, a species not previously recorded here #WildflowerHour

@Matt_J_ecology Yes! T ciliate

Some of the beautiful flora seen in the New Forest this week. Narrow Leaved Lungwort (Pulmonaria longifolia - a new one for me!), Pillwort (Pilularia globulifera), Petty Whin (Genista anglica) and Taraxacum ciliare (i'm pretty sure). #wildflowerhour

@crawley_mick That H.scotostictum photo looks familiar 😁 vascularplants.co.uk/product-page/1…

Now it gets even easier. Stem leaves 0, 1 or 2 with numerous basal leaves is Section Hieracium (left). Stem leaves 2 to 8 with just 2 - 4 basal leaves, often withered at flowering is Section Vulgata (right).

The Hawkweeds (Hieracium spp., Asteraceae) are apomictic (seeds without sex) and often regarded as impossibly difficult to identify (the key in Sell and Murrell covers 412 spp. and runs to 14 pages). The way to begin is with the lowland species and Mike Shaw’s user-friendly book.

@WahlgrenNiclas T leptodon is a larger plant with mid green leaves and twisted reflexed green bracts.

@BirdingCalvert Vilka karaktärer tar du den på? Har fått förslag om T leptoden. Den ska finnas i mina hemtrakter. T exacutum mer tveksamt. Men dessa smårter är nog för dåligt kända för att vara säker

Äntligen Nu blommar maskrosor igen. En i det stora komplexet ogräsmadkrosor Taraxacum sect ruderalia #biologiskmångfald

@wilde97859522 Check out T pectinatiforme

Which Taraxacum could this be, look bit like trilobatum?

@roxby_malcolm Enjoy! Can't believe we all got old (better than the alternative!)

I don't seem to post much these days but couldn't let today go by without a word! Just logged out of my work laptop for the last time. Retirement.........😎🥂
