Erythronium 2021

[Herman Mylemans]

After the snow was gone Erythronium caucasicum appeared very quickly (16/02/2021). Next picture 3 days later.
Finally on 23/02/2021 it was in full bloom.

Today Erythronium dens-canis ssp. niveum also starts to flower. So the Erythronium season has started here.

Here in my garden Erythronium multiscapoideum is alway the very first, starting to appear more or less on first of Febr with stunning leaves. The flowers though will start to bloom much later, even later as the first dens canis that started flowering 3 days ago.

Erythronium albidum

[Herman Mylemans]

This Erythronium had the wrong name. What can it be? Maybe Erythronium helenae?

[Ian Y]

I don't think it is E. helenae from what I can see more like a form or hybrid of E. oregonum.

Thank you Ian, I will change the name in E. oregonum.

[Herman Mylemans]

Ian, I took today a new picture of the inner side of the flower, the style is not straight. Isn't that something for E. helenae? The seed of this plant is collected in the wild.

[Maggi Young]

Oh yes, we can see the  bent  style  in the  new  photos, Herman - which does speak to E. helanae. The  style seemed straight in the  first  photos.

Thank you Maggi.

Thanks for the extra pictures despite the bend in the style I still think it to be a form or hybrid of E. oregonum I can see the filaments in the latest pictures that are not at all like those of E. helenae but are typical for oregonum.
The bend in the style may have been caused by damage you will need to inspect other flowers if it is consistent then it could indicate hybridisation between these two species is possible.

Herman Check out the pictures in the chapter on E. helenae in my book the link to the bulb log with that chapter is below.

Ian, it is the only flower for this year. I have E. oregonum on another place in the garden but they are not flowering yet. From the past pictures of E. oregonum, I know that they look different from this plant. I have also asked at Luc Scheldeman from who I have got this plant. His plants, from the same seedpacket, are named E. oregonum. I have also asked him to look if the style in his plants are bended or straight. I am still waiting for his answer.
Ian, I read your very good E-book regularly, there I saw the bent style for E. helenae.

Speaking of Erythronium helenae - the species has a fairly narrow range in the coastal mountains north of San Francisco, and much of the species' habitat burned in wildfires in 2020. Now that spring has arrived, the populations of E. helenae are blooming in profusion. This is actually a common post-wildfire response in Erythronium.  You can see photos people have posted on iNaturalist at this link: https://www.inaturalist.org/observations?place_id=any&subview=grid&taxon_id=59445. I don't believe you need to be logged in to view the photos. The large yellow "egg-yolk" in the center of the flower, the yellow anthers with terete filaments, and bent styles are the features that, taken together, distinguish E. helenae (and the related recently described species, E. shastense from north of Redding).

That's pretty impressive Maggi. I was thinking I hadn't seen that part of the garden in the Bulblog before...

E. sajanense is a new one on me, is it newly described?
