And I'm afraid Panayoti's delicious photos of Delosperma lawns got lost in the shuffle, such eye-candy, I'm particularly thrilled by D. dyeri with such brilliant silky orange flowers.

The colours are quite exceptionally cheering, are they not?  
The pictures speak volumes of warm days and buzzing bees.... very appealing in these dark cold days in the UK.
In contrast to McMark, I find the D. dyeri  with that bronzey tone to be a bit "grubby" looking. ::) I reckon if you want BRIGHT than you just go for it with the most screaming pink you can find. :o 8)

Maggi, how about this color form of D. dyeri, I really like the fact the plant has flowers of different colors and tones:
http://nargs.org/smf/index.php?topic=468.msg5121#msg5121

And I know you'll like this one, such a heavenly shade of lilac-pink, Delosperma 'Tiffendell', not the slightest but grubby.  I got from Panayoti, and it overwintered (a number of the "delos" did not):

If I want bronze tones I prefer Chrysanthemeums like my Uncle grew when I was little.... I don't think you're going to win me round to D. dyeri ... though I do admit the brighter pink eye is cute.

I'll stick with PK's strong purples  ;D

Actually I think that Chris and Joseps discussion is ok, its kept with good arguments and not with personal insults and I like the challenge in my attempt to figure out what they are talking about...

What you can see is that they both love delospermas a little bit too much! I tried hard to understand too.

I only underline that i did not "broke in" Josef's "private files". They simply could be found in the past directly accessible on Josef's HP and in another internet group without responsibility from my side.
No problem, I didn't speak about responsibility, the files are not secret.

I like these sort of 'off colours' I do love Aizoaceae in general, and will be happy if I get any to survive here, but I especially like the flowers which are neither brightest yellow nor brightest magentas/purples- I like the clear pinks (meaning rosey shades of any intensity)  and  apricoty/bronzey etc...

i just got my Pantone color chart out to check on Cohan's marvellously descriptive apricoty/bronzey delospermas. No sign of them.....but they sound so much nicer than Pantone solid to process coated P501 C.  ;)

Think PK’s selection of splendid photos has quite sure not been chosen without a deeper sense by Panayoti (正确观看, 特级大师的高山花卉?).
They are showing a certain allied cluster of natural wide spreading, but local predominant only spot-like occurring alpiniced plants.
Topical rather completely unknown in science, but in my eyes not really too difficult to explain and classify.
Delosperma sp. 'Scotland' also belongs into this complex of plants.

With a slight modification i agree with the excellent identification of D. nelii.
I do not agree with the ID of D. carterae for the pretty nice D. carterae 'Carlile Pink', much more likely here is the derivation from a D. sp. 'Scotland' form, found in trade errounesously under D. carterae.

Beside Sani Pass and Giant's Castle further and newer localities of the undescribed rocking alpiniced sister already have been comfortably documented (Photos/GPS) in NW, N & NE Lesotho (one notably above 3100m).
Even one of them is showing the rocking sister diving in a rivulet...

Delosperma alpina, Dold s.n. (Hogsback Mountains) - http://de.wikipedia.org/wiki/Hogsback_%28S%C3%BCdafrika%29




With topical available tech it is rather verisimilar, if not even evident that the original locallity, found by R. A. Dyer in 1926 (D. alpina & D. dyeri) contained as well a 3rd species, also described under Delosperma and enabling the necessary singularity for a very probable rediscovery of this until today unkown old Dyer location...

LOL-- though, I suppose Pantone is more reproducible.....

Since Hartmann and Niesler use the term hypanthium in an extraordinarily strange manner in Bradleya 27 (2009): 69-120,
I decided to collect definitions of it.

The Elements of Botany by Asa Gray

237. The torus or receptacle is the end of the flower-stalk, or the
portion of axis or stem out of which the several organs of the flower grow,
upon which they are borne.

Oxford Dictionary

hypanthium [botany] | hypanthia [plural] | plant part [type of]

a cup-like or tubular enlargement of the receptacle of a flower, loosely
surrounding the gynoecium or united with it

Collins Dictionary

hypanthium [botany] | hypanthial [adjective, related]

the cup-shaped or flat receptacle of perigynous or epigynous flowers

A Dictionary of Plant Sciences, Oxford University Press 1998.

hypanthium A cup-like or tube-like enlargement of the floral receptacle or
base of the perianth that surrounds the gynoecium and fruits.

Systematics of Plants at the University of Illinois

Hypanthium (floral cup) – a structure derived by the adnation of the
perianth bases and stamens. It is variously shaped.
PERIGYNOUS FLOWER (if hypanthium not adnate to ovary) – a flower with
perianth and androecium arising from a floral cup that is NOT adnate to the
ovary. Remember – the ovary is still superior!
EPIGYNOUS FLOWER (if hypanthium adnate to ovary) – a flower with perianth
and androecium apparently arising upon the ovary


The following references are interesting too.
http://dx.doi.org/10.1086/376876  
http://dx.doi.org/10.1086/324528

So hypanthium is not restricted to epigynous flowers and contains the adnate
torus cup and bases of flower parts. It is cup-shaped and not collar-shaped
as presented by Hartmann and Niesler.

In my drawing the adnate tepal-stamen tube above nectaries might be
understood as belonging to hypanthium, sensu amplo, too.
It is of course rudimentary in Delosperma.

A brand new absurd concept of hypanthium invented Simpson in his Plant Systematics.
To be original, he removes the parts adnate to the ovary.

Hello,

anybody growing Delosperma dyeri in Europe?
I am looking for a cutting or for some seeds!

I have spent all day moving Delopserma MC 2999 (from Rob Potterton) into the sun in the hope of the flowers opening for a picture. They are refusing to co-operate.
I also found a self seeded one (standard purple flowers) on one of the Rock gardens. Now I have never reused compost on that area and never planted out any Delosprma there, so a bit of a mystery. BUT, the point of this rambling is that it has survived over last Winter which was pretty cold here. Picture will follow if the flower ever opens, if the sun ever shines that is!
No sun but this one was in flower

Here is Delosperma MCB 2999

And D. congestum for comparison.

And this is my self seeded one. the flower is probably only 1 cm across.
