这是一个未被登记的品种，但是从各个方面来说它都应该是一个被广泛接受和认可的品种，它可能没有被发表过，它的培育者也可能还没有确定它的正式名字。在火宵之月的生石花图谱中，它被记录为v. hallii，它确实不应该是从C111中培育出来的，因为不具有欧翔玉的特点。
关于这个品种的更多信息，欢迎各位补充。
在Keith的网站里有这样的记录。
*L. hallii ‘Sakkie’s Green’. A title sometimes seen on social mediaor the Internet relating to green bodied specimens of L. hallii.However, there has been no published description, and in any case it is unclearif the origin is var. hallii or var. ochracea, the latter alreadyhaving the green cultivar ‘Green Soapstone’ assigned. Currently an unacceptedepithet.
于是我和Keith进行了一些讨论，下面是邮件里的部分信息。
（Andy to Keith）
……
'Sakkie's Green' is a widely used epithet, it is different from 'Green Soapstone' in many ways.
In ICNCP Rec 21A.1 , When a cultivar can be assigned to a taxon at species rank or below, the name of this taxon, or its unambiguous common name, should accompany the cultivar epithet, as this conveys further information about the plant which may be valuable to users.
It is a recommendation, not a provision.As we don’t know whether it is var. hallii or var. ochracea, my book is to record this as L. hallii 'Sakkie's Green'+ discription. When my book is published, will this be a establishment for 'Sakkie's Green' if not against breeder's wish?
(Keith to Andy)
……
You mention ‘Sakkies Green’. Howdoes ‘Sakkies Green’ differ from ‘Green Soapstone’? If you can give me a clear distinction and publish that, the epithet will be registered.Otherwise the epithet will remain as an excluded name on the register with allthe others.
（Andy to Keith）
……
When we describe acultivar, we use distinct characteristics. But we shouldn't forget the classification criteria in Professor Cole's book.
1.'Sakkie's Green'remains green regardless seasons or sunlights. 'Green Soapstone' often turn yellow with more sunlights, which is the reason why we call it "Yellow hallii". Characteristics influenced totally by breeding conditions can't form a new cultivar, however it is difficult to turn a 'Sakkie's Green' to yellow color.
2.'Sakkie's Green' has distinct margins and regular network of channels with small islands, the outer top edges are well-defined. 'Green Soapstone' also has truncate profile, but the outer top edges are round, network of channels is shallow and somtimes not obvious.'Sakkie's Green' is more likely to be a var. hallii to me.
3.Not mentioned in Professor Cole's book, it is also important to observe the babies in my opinion. I have different open window aucampiaes, KO, L2-87, ROW. Sometimes it is difficult to tell apart adult plants with fully opened windows. When they are babies(0.5-2 yearsold), however, KO has round head and short fissure, L2-87 or ROW has elliptic head and long fissure across lobe. Under same breeding conditions(it isnecessary for industrial production in my greenhouse), 'Sakkie's Green' babies are always green and bigger, 'Green Soapstone' babies are yellow and smaller.One year old 'Sakkie's Green' is often 1.5cm while 'Green Soapstone' no more than 1cm at same age.
4. Some 'Sakkie's Green' have raised spines in some years. These "some 'Green Soapstone'" are not a few,but are many.

Thank you for your e-mail and photographs. Yes you make a good case for ‘Sakkie’s Green’, but not all specimens I have seen are like the ones you show (see attached). The difference has to be obvious and consistent in the adult form, but if your plants are always darker green and more rugose, your published description will establish the epithet. ‘Green Soapstone’ is a green aberration, so ‘Sakkie’s Green’ would have to be different, perhaps “a dark green, rugose aberration” or something like that. If a cultivar need a label to distinguish itself, it is not a cultivar. ----------------- 新的回复：

……
Regarding ‘Sakkie’s Green’, I am trying to contact the originator who I believe is Sakkie Simon of Namibia. He used to exchange plants with my old friend Tok, but I have never met him personally.
Because of your comments I went to the Cole monographs and looked up the description of ‘Green Soapstone’. There it is indeed recorded as “greenish-yellow”, so you are correct in your observations, well done. I have amended the cultivar register now which will make establishing ‘Sakkie’s Green’ very much easier when the time comes. I will inform you if I hear back from Sakkie Simon himself.
