[Taxacom] Tetrastigma tuberculatum: nom. illeg.?

As far as I can tell, the ICBN makes no provision for "nomina dubia".
But the bottom line is that if Latiff--for whatever reason--considers
Cissus mutabile to be conspecific with the other taxa he lists under his
T. tuberculatum (and by listing it in synonymy he apparently did), then
as the oldest available name, the correct name in Tetrastigma would be
T. mutabile.

I'm afraid this is not the correct solution. The type material of Cissus
mutabilis is hardly identifiable, as was already stated by Miquel [Ann.
Mus. Bot. Lugd. Bat. 1 (1863) 75]: (my translation) "The specimens
available surely are incomplete, with the tendrils and flowers being
totally absent. It seems close to V. landuk. I have therefore little to
add to the diagnosis cited ... The form of the stigma and the number of
seeds seem to provide the essential characters".
There are no sheets in Leiden on which Blume wrote this name. See our
site http://145.18.162.53:81/c8 Go to All collections. Enter Vitis
mutabilis (error by the person who entered data in this database). 

We do have two labeled as Cissus montana Blume, an unpublished name,
which were later labeled by Miquel as Vitis mutabilis. One has the note
"Decbr.", which is against Blume's remark "Floret: Julio -- Sept."
Latiff has not labeled these specimens. Meijer, the Rafflesia
specialist, labeled it as the type, but I suggest to treat this name as
a nomen dubium. 

The correct name, according to Latiff's summary is Tetrastigma
rafflesiae (Miq.) Planchon. This material is but slightly better than
that of C. montana, but it has been seen by Latiff and was later
confirmed by Meijer. It is mentioned in Korthals's unpublished diary and
we have two drawings of the Rafflesia, which is R. hasseltii, which is
known to prefer Tetrastigma leucostaphylum auct. I am therefore fairly
sure of the identity of this material, and of course the name is
extremely suitable.

I have just finished a note on this problem, which I will send to Latiff
for review. I hope he will agree with my conclusions.

Sincerely,

JeF

Dear Dr. Latiff:

 

Thank you for helping to clear up this nomenclatural problem.  I will
correct my records to reflect Tetrastigma mutabile (Blume) Planch. as
the correct name for this taxon.

Dear sirs

Thanks very much for enlighting me of that "kiss of death" as per
discussion with regard to my publication of a new combination for the
host of rafflesias in Malesia, Tetrastigma tuberculatum Honestly I was
not aware of the name Cissus tuberculata Jacquin, should not have
occurred as I have Index Kewensis and IPNi with us However, after going
thru the discussion, I accepted my error and wil take the necessary
steps to remedy the taxonomic situation.
The alternative is to accept T. mutabile (Blume) Planchon as the correct
name for this taxon Thanks latiff

I thought I knew the Code pretty well but overlooked Art. 58.1. Despite
being published as an avowed combination, Tetrastigma tuberculatum
Latiff 2001 is apparently to be considered a nom. nov. for Cissus
tuberculata Blume (non Jacq.), with the same type.



Unfortunately there's more: at the same time he made the "combination",
Latiff synonymized several species under T. tuberculatum: Cissus
mutabilis Bl. (1825), Tetrastigma mutabile (Bl.) Planch. (1887),
Tetrastigma encephalospermum Ridl. (1926), Vitis kunstleri King (1896),
Tetrastigma kunstleri (King) Craib (1926), Vitis rafflesiae Miq.
(1863-64) & Tetrastigma rafflesiae (Miq.) Planch. (1887). If I'm looking
at these names and dates right, he should have taken up T. mutabile
(Bl.) Planch. as the correct name for this taxon, as Cissus mutabilis
Bl. (1825) is the next oldest name after Cissus tuberculata Bl.
(actually published at the same time) and therefore has priority over T.
tuberculatum Latiff (2001) IF all these taxa are combined under one
name.

I don't have the ICBN handy, but isn't this one of those cases where the
correct name becomes Tetrastigma tuberculatum Latiff?
