2023 Yorkshire Hawkweeds - Early June

Updated: Jul 7, 2023

A weekend spent with Brian Burrow looking at early flowering hawkweeds in VC64 on 3rd-4th June

Stayed at the Dale Farm B&B. 2 days of wall-to-wall sunshine

Started with a pre-breakfast (1.5hrs) walk around the Ingleton waterfall trail. Lots of Hieracium cravoniense along the river - long dense simple hairs, stylose heads, dark styles SD705746

BB: "it is a form with more than the usual number of glandular hairs. When typical it has very few. This is the same plant as is found lower down at the Quarry Wood pond. This was originally put in H. ampliatiforme by David and Vincent, because of the more numerous glands, but it does not match that species properly. We now think it is a form of H. cravoniense."


Hieracium crebridentiforme was growing next to a stream - few stellate hairs on the bracts and few simple hairs on the peduncle, hairy upper leaf SD700737

Met up with Brian and the group at 10am at Ingleborough. Walking up to the first scar Hieracium pseudointegratum section Hieracium SD74867762 with discoloured styles, small heads and cuneate bases to the stem leaves. Some plants with toothed leaf stems.

Hieracium cymbifolium section Hieracium nestled in the limestone at SD74757710. Stellate hairs on both sides of the boat shaped leaves making them soft to the touch.

Near to that Hieracium triviale forma sejunctum with long teeth on the stem leaves

Not all hawkweeds here is baneberry Actaea spicata growing in the pavement in a few places and silky lady's-mantle Alchemilla glaucescens along the path.

Hieracium brigantum section Stelligera SD74317618 was still a few weeks away from flowering but still recogniseable by its long bulbous hairs on its leaves

We chanced upon Hieracium dicella section Stelligera at SD74187653 with its elliptical glabrous leaves, discoloured styles and only a few simple hairs on the peduncles

A few more Hieracium cymbifolium seen on the way down then we headed Horton Quarry.

Hieracium monstrosum section Hieracium grows near the entrance at SD80397224. It was good to compare with the plants I had in Tavistock a couple of weeks earlier.

In the same spot was Hieracium festinum section Vulgata. Not in flower yet but readily identifiable with its long narrow elliptcal base leaves and stellate hairs under the sharply toothed cauline leaves

Back to the car park at Ribblehead Station and a walk through to the disused quarry opposite. Here is Hieracium caesitium SD76597880 another spotted member of section Hieracium growing in amongst numerous Hieracium grandidens

Hieracium crebridentiforme grows on a sheltered rock face at SD77167855 recognised by its large ovate leaves and bracts lacking stellate hairs along the edges

Hieracium jonesianum section Tridentata has been reintroduced into the quarry and is beginning to spread (but rabbits doing there best to stop this) . The plants growing as Seathwaite formally named as H. mirandum are now thought to be H. jonesianum

Near to the the Cumbria border Hieracium dentdalense SD77748428 a newly discovered species growing along the Dentdale. Seperated from other exotericum by its stellate hairs underleaf.

Later in the evening I went up to Keld Head Scar. After some searching around I found Hieracium cymbifolium growing on a large bolder, with furry (stellate hairs on both sides) boat shaped leaves

Not far from there was Hieracium stenopholidium with a combination of yellow styles and stellate hairs underleaf (glabrous on top) SD6921 7635

BB: "Is the plant that David and Vincent called H. stenopholidium. I also collected a specimen from the same area. After looking at both of our specimens I have some reservations and neither fully match my other specimens of stenopholidium. Our plants have slightly discoloured styles (should be pure yellow) and some ligule hairs (should be glabrous). I think we can still put it under H. stenopholidium with a note of the differences. (or call it H. aff. stenopholidium)."


Continuing down hill I came a across a group of hawkweed next to a wall. The first species is yet to be named and the second one was a form of the recently discovered Lang Scar plant.

BB: "Is not crebridens. But this is the nearest species. Strangely I collected a specimen from a good colony which looked different at SD691764. This matches your plant. Both have some characters of H. crebridens and I can see why you ended up there. But there are enough differences for us to keep it separate."

BB: This is common in the area and is quite variable. I think I said to you it can have (0)1-3 stem leaves and may have a broad inflorescence.


Day 2

We started the day at Langcliffe SD8192 6461 looking at Hieracium oblongum growing on the bridge. Short glandular hairs with no (few) stellate hairs on the bracts.






On the same bridge was Hieracium sylvivagum
