Updated the title of the post,
Just let me know when the species name has been decided and approved
The Artocarpus taxonomy revision paper was published today. Such papers are purposely put in open-access journals, as the authors believe taxonomic changes to be important enough that the wider community has access and that the adoption is contracted rather than drawn-out (resulting in more confusion). As was anticipated, Kwaimuk or Gwaimuk (formerly Artocarpus nitidus subsp. lingnanensis) was renamed to Artocarpus parvus. I should repeat that it was NEVER A. hypargyreus, so those wanting to "keep this name" because they are "used to it" need to comprehend that this was a case of mistaken identity.
I have already made a thread on true A. hypargyreus, with photos, so you can find that if you are interested. But the gist is that nobody has it in cultivation. It is indeed called something like "white kwaimuk" transliterated from Cantonese, but it is not related (in the same clade) to kwaimuk. There are some other important changes mentioned in the paper.
A. nitidus subsp. nitidus was renamed to A. lamellosus. It is endemic to the Philippines and its common names are butong and kubi (Tagalog).
A. nitidus subsp. humilis was renamed to A. humilis. Common names are Beruni and Selanking
A. nitidus subsp. borneensis was renamed to A. borneensis. Common names are Tampang, Beruni and Selanking
A. nitidus subsp. griffithii was renamed to A. griffithii. Common name is pizhenye kwaimuk, which transliterates from Chinese as "lancelote-leafed kwaimuk"
The paper didn't really cover common names, that was my own addition, though I wish they had. I am of the personal opinion that "kwaimuk" should be one word. The fact is there is no standard of how pidgin Chinese is brought into Western languages. But basically writing kwai muk is the same writing ly chee or long yan. And it is actually gwaimuk properly transliterated, alas this isn't a big deal and is probably too late to correct.
You will find a lot of photographs and species-ID keys in the paper. But this paper just concerns the subgenus Pseudojaca, so all of the jakfruit, breadfruit, marang, pedalai, keledang et cetera are not included (they continue to have their same binomials).
As for when the proposals will be "approved" there is no official measure of this, though it should be mentioned that the lead author Dr Elliot has done most of the annotations for Kew's herbarium, and so the database POWO should be updated to reflect the new names soon. In a couple of years Flora of Singapore Moraceae will come out and the system will be included in that. If someone is a member of the Artocarpus group on FB, please post this paper there.
