delosperma & aizoaceae

[Hoy]

I don't grow many Aizoaceae outside but this one has proved hardy for several years now. It worst enemy is slugs. I have no name though.

[Rogan]

I think this is Lampranthus amabilis and I found it growing just above the high tide mark on the southernmost beaches in South Africa, in the de Hoop nature reserve. I brought a small piece home for identification and now have several growing here and there in the garden - it is very happy in a pot too and flowers prolifically.

Delosperma sphalmantoides in full bloom.

[Great Moravian]

For your information
Delosperma sphalmanthoides S.A.Hammer differs from other Delosperma species in densely tufted stature, filaments at basis densely hirsute and to ovarium adpressed holonectaries.
Therefore I renamed it to
Komsbergella sphalmanthoides (S.A.Hammer) Niederle in Skalničkářův rok 75:28. January 2017.
Basionymum: Delosperma sphalmanthoides S.A.Hammer in Cact. Succ. J. (USA) 65: 123. 1993.
Other Delosperma species might belong here too.

The genus Ectotropis N.E.Br. was established for one species, E. alpina N.E.Br. (Brown, 1927). Hartmann & Schröder (2013) suggested that the etymology of Ectotropis was not explained by Brown (1927). This is incorrect, the etymology (ecto-tropis = turning outwards) implicitly but clearly explained by Brown (1927) in the descriptio generico-specifica of the genus and species. Brown (1927) namely stated that the interlocular septa were adnate to the capsule valves instead of to the bottom of the capsule as is the normal situation in Mesembryanthemaceae. As a result, the septa were transported outwards attached to the expanding valves when the capsule was opening, and therefore the seeds were not separated by septa adnate to the capsule bottom in an open capsule as is the normal situation in the family.

Brown (1927) established the new genus, which seemed to be strongly supported by a feature not encountered in other species of Mesembryanthemaceae.
I have observed living material of the two species given to me by Marek Chaloupka. Their interlocular septa are adnate to the capsule bottom and separating the seeds in the open capsule.  I am not convinced that Delosperma alpinum and Delosperma seanii-hoganii are closely related. Floral characters mentioned by Hartmann & Schröder are clearly adaptations to pollinator who enforced risen stigma. They achieved the rising of the stigma by different means. In the former, the whole ovary top is cupola-like and smooth, whereas in the latter, the centre of the ovary top is pyramid-like with longitudinal ribs. Furthermore, pale green distantly separated nectaria form a discontinuous circle adpressed to the ovary in the former, whereas dark green holonectarium forms a star-like pentagon distant from the ovary in the latter. The leaves of Delosperma alpinum are normal papillate  Delosperma leaves with short sheath whereas the leaves of Delosperma seanii-hoganii are except few small papillae on the margin smooth and their basal half is transformed to a thin sheath whereas their apical half is succulent and rounded. I am convinced that the properties mentioned above separate Delosperma seanii-hoganii from the genus  Delosperma too. Therefore I have established a new genus Sanianthos for it.

I expect that the acceptance of my newly coined names will take at least ten years. The previous were accepted by the late Prof. Hartmann after five years, but she was a skilled specialist.

Hallo Josef,

Hammer hat bereits 2015 das Delosperma sphalmanthoides in Daggodora sphalmanthoides S.A.Hammer gen. nov. umgruppiert.
MESEMB STUDY GROUP BULLETIN.3.2015
Also ist das hier geschriebene ungültig.

Ectotropis alpina syn. Delosperma alpinum

Why are you writing these things here? This belongs to an international specialist journal. Not in a forum.
Please stop writing such no accepted things here.

The entry for Daggodora sphalmanthoides in IPNI was done on 5 December 2016.
http://www.ipni.org/ipni/idPlantNameSearch.do?id=77158919-1&back_page=%2Fipni%2FeditAdvPlantNameSearch.do%3Ffind_infragenus%3D%26find_isAPNIRecord%3Dtrue%26find_geoUnit%3D%26find_includePublicationAuthors%3Dtrue%26find_addedSince%3D%26find_family%3D%26find_genus%3Ddaggodora%26find_sortByFamily%3Dtrue%26find_isGCIRecord%3Dtrue%26find_infrafamily%3D%26find_rankToReturn%3Dall%26find_publicationTitle%3D%26find_authorAbbrev%3D%26find_infraspecies%3D%26find_includeBasionymAuthors%3Dtrue%26find_modifiedSince%3D%26find_isIKRecord%3Dtrue%26find_species%3D%26output_format%3Dnormal&show_history=true
I wrote the text earlier. I agree that Daggodora has priority and am not happy that I produced a synonym.
If the information in IPNI were one month earlier, I would naturally not do it.
Nevertheless, the genus name Komsbergella is validly published and homotypic synonym in virtue of ICN.
The notions accepted and not accepted are not accepted by plant taxonomists but solely by strange people.
I will write what I think is important and use names accepted by me. I naturally accept Daggodora because of priority
and refuse Komsbergella. I clearly explained why I accept Delosperma alpinum and refuse Ectotropis alpina.
You can of course accept what you want.
Thank you for correcting my lapsus and attracting attention to Daggodora.

Please read carefully
Official refusal standpoint of the International Association for Plant Taxonomy to binding lists of so-called accepted names can be found at

They say

fostering excellent science generally involves community engagement rather than regulation

The concept of an authority ordering binding scientific results is shocking.
Plant taxonomy is a science generated in brains of different individuals.

Science depends on agreed definitions or standards.  This proposal to standardise taxonomy (original publication here, probably behind a paywall ) is surely only part of ongoing efforts to improve clarity.  Like all science and scientific conventions, its conclusions would remain contingent on new evidence, so really I don't see the problem . 

[Great Moravian]

This proposal to standardise taxonomy (original publication here

This is precisely the idea replied and refused in the reaction by IAPT. The article is rather stupid.
Involving lawyers in taxonomy is gently speaking unhappy.
Conservationists should protect particular populations, small or large, and not
bother about taxonomy which has nothing to do with conservation.
Money available for particular conservation programmes is clearly
in the background, science doesn't need any regulation.
In this country, organisms and habitats are protected which in southern or eastern
part of Europe are common and don't need any protection.
We naturally don't require money for their protection.

[Great Moravian]

By the way, it is impossible to provide precise definition of a species
even for quite small groups of plants. Species are not equally old.
There exist clearly delimited old species and groups of young
species delimitation of which is rather complex, possible merely
on the basis of complicated statistical methods.

Braunsia maximiliani (with a Lachenalia sp.)
on the coast south of Paternoster, Western Cape, July.

[Peter II]

Braunsia maximiliani is a very interesting plant. Unfortunately, mine did not last long.

[Great Moravian]

Despite the Delosperma and Malotigena names published by me were accepted by the late
Professor H.E.K. Hartmann with Delosperma seanii-hoganii transferred to Ectotropis,
there are still comical attempts to probematize them. Someone claimed that
Delosperma adamantinum is a synonym of Delosperma monanthemum.
It is certainly not the case.
The protologue of Delosperma monanthemum is at
https://archive.org/stream/journalofsouthaf33unse#page/70/mode/2up.
There are the following basic reasons.
1. Formal reason
Delosperma monanthemum is nomen invalidum.
http://www.ipni.org/ipni/idPlantNameSearch.do?id=57405-1
2. Thing-pertinent reasons
Major differences.

Delosperma adamantinum	Delosperma monanthemum
leaves and stems conspicuously papillate	leaves and stems glabrous
petals bicoloured, upper half crimson, lower half white	petals pinkish purple
staminodes white	staminodes pink

There are more differences for a trained botanist.

My Delospermas put a lovely show.....
