I found this over in the cactus forum, and wanted to share it with all of you. Some fascinating photos and information.
Right now David is in Turkey researching a new species of Sempervivum.


ACTA SUCCULENTA, the new, free online Journal

A new, free online journal dedicated to the world of succulent plants is now available online: Acta Succulenta.

It's downloadable in 3 distinct editions (English, French and Italian), free of advertising. I'm the Editor of the Journal.

The download is free.
The size of the pdf file is quite big, so please be patient while it downloads.

Any article about succulent plants is welcome.

I hope you enjoy Acta Succulenta.

Good deal! I'll have to check it out when I get some time.

Chris it really is an amazing journal. The journal is filled with information and photos for each plant featured. I am so excited about the research David is doing right now, in Turkey. He said they have found a new Sempervivum.

That's exciting!

The photos are amazing!! How cool!! A new semp! Thanks for sharing this great journal Lynn!

I thank David for finding us and posting here at ATP. I really want to follow his journal, it will be amazing what we will learn from his research.

Ooops, I didn't explain well...

I'm in Turkey now, close to the Iranian border (internet is excellent), for a field research about Sempervivum, but the new species I'm going to describe (with Gérard Dumont) is from... it's a surprise!

Can you forgive me if I upload some pics just taken here?

Sempervivum minus



Sempervivum davisii

David, I can hardly contain my excitement. The photos are wonderful. Do I have your permission to add the photo of S. davissi to our Sempervivum database here at ATP?
You can post any of your photos here, we would be filled with joy to see them.

Would this be the same as this S. davissi?
Hen and Chicks (Sempervivum davisii from road to Artvin, Ardahan )

certainly another pick-up place Lynn; unlikely he took this photo at the same road ;-)

So Peter, would we make a separate entry in the database, Sempervivum davisii?

we also can ask for more location-infos and make a new locale-form-entry....but there would be no more photos because it isn't in collections;

I think we should collect such photos in a pure genus-entry;

The new entry is done.
Waiting to hear from David, to see if we can add the above photo to the database.

How exciting that must be, to see them growing in their natural habitat.

How beautiful! Thank you David! Enjoy your research!

Hi, I'm still alive ;-) and internet works better here than at home!

You are free to use my pictures in your database

S. davisii is from Yusufeli, not far from Artvin.
S. minus from South of Rize.

Why don't you create a sub-database for wild Sempervivum?

I can send you other photos of wild plants (from everywhere they are growing, included Iran) once at home, but this will take a while ;-)

Or better, every issue of Acta Succulenta I'll send you some pictures of the plant described or mentioned in the column "Urcaela" (Houseleek in my dialect).

Do you agree?

Thank you so much for the permission to use the photos in our database. They will be protected from unauthorized use.

We do have specie sempervivum in the database, some of which are the same specie, but from different areas.

Here you go David. See if this look right.

Davide,

What a GORGEOUS publication. You should be commended for gathering such wonderful information and glorious photographs.

If I had one comment it would be to your comments on the cultivars of S. calcareum. I grow both 'extra' and 'Pink Pearl' and think both clones are well worth growing and sufficiently distinct from other clones. The symmetry of 'Extra' makes it one of my favorites. However, as you note, there are NO bad calcareums!

In the US calcareum blooms very rarely but I have used it as a parent in some of my earliest crosses as it produced lovely fluffy pollen. The cross of 'Cleveland Morgan' (predominantly montanum breeding) X S. calcareum gave 'Greenwich Time', which is a velvety purple in spring but turns to a velvety version of calcareum later in the season. It is nearly sterile, unfortunately. Because it was so easy to make hybrids with calcareum pollen I'm thinking that the complete sterility of the hybrids may have prevented the widespread occurrence of such events in nature. 'Greenwich Time' is certainly the exception in fertility among the sempervivum hybrids. The flowers of the hybrid are very close in color to calcareum too.
