  Colocasia name
From: "Marek Argent" <abri1973 at wp.pl> on 2011.08.21 at 23:02:01(22183)
Hello,

Which name is the proper one?

Colocasia esculenta var. antiquorum (Schott) C.E. Hubb. & Rehder

or

Colocasia antiquorum Schott

On the web (IAS, Tropicos, IPNI, CATE) I can find both combinations

and I really don't know which one should be used.

Best,

Marek Argent

Hi Marek

Neither. Both are simply Colocasia esculenta, as per our previous correspondence.

Best

Hello Peter,

I'm confused. Isn't Colocasia antiquorum SCHOTT a valid species? At least in Li Heng's and your treatment in the Flora of China it is.

Best,
David

Hi David,

Yes, it is a valid NAME but it is NOT a good species - the typification was fouled up by Schott, who typified (certainly in error) on a Linnaeus specimen is is without question C. esculenta.

Mea culpa we fouled up in FoC. The DESCRIPTION in FoC is correct but the name is wrong. It should be called C. fontanesii.

Very best

Peter

Hello,

And what about Colocasia fontanesii?

It is listed in IPNI as a species: http://www.ipni.org/ipni/idPlantNameSearch.do;jsessionid=0B8049D3E21ED7D5BA9FE7D4B9104BF3?id=86590-1&back_page=%2Fipni%2FeditSimplePlantNameSearch.do%3Bjsessionid%3D0B8049D3E21ED7D5BA9FE7D4B9104BF3%3Ffind_wholeName%3DColocasia%2Bfontanesii%26output_format%3Dnormal

in Tropicos, too, but there is also a synonym C. esculenta var. fontanesii:

http://www.tropicos.org/Name/2102376

http://www.tropicos.org/Name/2105987

in the IAS pages it is regarded as a cultivar of C. esculenta:

http://www.aroid.org/cultivars/display.php?select=1724

http://www.aroid.org/genera/serveimage.php?key=4589

Cate-Araceae as usually is unaccessible.

I always knew that "fontanesii" is a Colocasia with a glossy leaf surface

and purple or burgundy petioles, but I never really wondered about its taxonomic status.

Best,

Marek

Hi Marek,

Colocasia fontanesii is a good species; it is what Schott INTENDED to describe when he published the name C. antiquorum but because Schott blundered and typified his name antiquorum on a specimen that is C. esculenta the first available name for this glossy-leaved plant is C. fontanesii.
