Old name vs. new name

ITIS still use Psidium cattleianum as the valid name, stating P. littorale (and others) as being a synonym:
"Psidium cattleianum". Integrated Taxonomic Information System.
What's the real deal here? Tommy Kronkvist talk contribs 08:35, 23 January 2008 (UTC)[reply]

ITIS is extremely out of date. I used to work for USGS and names I submitted three years ago still haven't been put up. I'm not completely sure that P. littorale is correct, but I think it is, and the point is that ITIS shouldn't be taken as a source for current taxonomy. KarlM (talk) 19:02, 23 January 2008 (UTC)[reply]

As of June 2011, both the TROPICOS and ARS-GRIN taxonomy databases consider P. cattleianum the correct names.113.20.67.35 (talk) 23:22, 9 June 2011 (UTC)[reply]

I'd like to move the page to P. cattleianum. this paper from 1995 gives a very plausible-sounding explanation that the names got mixed up because the publication dates were very close, so it is simply that the name P. cattleianum has priority. Nadiatalent (talk) 18:05, 9 October 2011 (UTC)[reply]

I would suggest making a note of P. littorale in the actual article. This is the name used in AUS and NZ. Also we call lemon guava by another name: yellow cherry guava. Wouldn't hurt to put both names. Tommy1441 (talk) 05:02, 17 December 2012 (UTC)[reply]

Ok perhaps it is just too confusing, especially given that there are variants (lucidum and possibly longipes) within this species. We really should encourage consolidation and minimizing of synonymous names. Cattleianum is the favored name in the scientific community, so I will go ahead if there are no objections and change the littorale in the article to cattleianum. As for common names, I favor Peruvian guava then cattley guava. Calling them strawberry, lemon or cherry guavas is just silly, they are unique tasting fruits and there is nothing wrong with calling it Red or Yellow Peruvian guava. Tommy1441 (talk) 18:29, 24 July 2015 (UTC)[reply]

After doing some thorough research at the USDA's Germplasm Resources Information Network (GRIN) it is clear that the taxonomy is more complicated then the article goes into, and quite frankly there needs to be an overhaul. There are in fact three subordinate taxa: two variations and one form. There are 2 yellow-fruited taxa and 1 red one. The common names are all over the place but that will be sorted too in time. For now, can someone do the minor change on the name of the species and relevant links. I.e. change cattleianum to cattleyanum. Indeed the cited source uses cattleyanum and this spelling is also recommended by the International Plant Names Index (IPNI)here. Tommy1441 (talk) 21:38, 24 July 2015 (UTC)[reply]

var longipes same as var cattleianum

Am I right that var cattleianum is likely the same thing as var longipes? Various sources seem to suggest so (and var longipes also has red fruit) but I'm not that familiar with sources for plant taxonomy. The longipes name seems more common here in NZ[1] Nil Einne (talk) 11:57, 21 December 2008 (UTC)[reply]

lemon guava is sweeter not more acidic

Sorting out confusion over taxonomy and common names

This article needs serious edification. Of the many different synonyms for cattley guava (and there are about 20 listed by the Germplasm Resources Information Network) one that never came up is 'Peruvian Guava'. Not sure why that name was included, as it is virtually never used, and, is not even where this species originates. There is yet more confusion over other common names used, notably 'strawberry guava', 'cherry guava' and 'lemon guava'. The assumption many people make, and is reflected in this article, is that 'strawberry guava' only refers to the red-fruiting form, while the yellow-fruiting form is referred to as 'yellow cherry guava'. In reality, strawberry guava and cherry guava are interchangeable, so that you can have yellow strawberry guava or red cherry guava, for instance. The name combinations however are asymmetrically in use. 'Lemon guava' is used exclusively for the yellow-fruiting form, although one can note that names such as this are problematic. This is because the 'lemon' is used as a marker for the variety, while 'guava' is merely the genus. In other words, such a name is missing the species, which is a rather imbalanced and ambiguous way of misrepresenting a fruit's classification. Some people claim that the 'strawberry' and 'lemon' are references to subtle differences of flavor, although that is hyperbolic pseudo-intellectual waffle. Once again we should be careful about using names with no specificity. Using just one word in front of guava, but attempting to demarcate one of the colored varieties, is incorrect. These varieties are not botanically a kind of guava, but a kind of cattley guava, which is what this article is about. This article and indeed most of the scientific literature favors the common name 'cattley guava', and, at lower taxa, the names 'red cattley guava' and 'yellow cattley guava'. An introduction that promotes this is in order. The body of the article and image subtitles however sway from this, which is something that needs to be addressed. Having said all that, the red-fruiting variety can theoretically be called just 'cattley guava' as this was the first of the varieties to be named and classified.

Now as for taxonomy, the International Plant Names Index and the USDA's Germplasm Resources Information Network are in agreement over the scientific names and subtaxa, which underwent some reorganizing in recent years. Psidium cattleyanum var. longipes (red fruit) was renamed to Psidium cattleyanum var. cattleyanum. Psidium littorale (yellow fruits) was reclassified as a variation of cattley guava, to be Psidium cattleyanum var. littorale. To make things more complicating still, there is another yellow-fruiting subtaxon Psidium cattleyanum f. lucidum which is a form of (P Cattleyanum var. cattleyanum), meaning it is more related to the red-fruiting variety than the other yellow one. As this is not the one in common circulation among farmers and growers, I think it would be best to not confuse readers with it. So, summing up, the three subtaxa are: · Psidium cattleyanum var. cattleyanum (red type) · Psidium cattleyanum var. cattleyanum forma lucidum (obscure yellow type) · Psidium cattleyanum var. littorale (mainstream yellow type). See USDA's GRIN for the taxonomy. Will edit the intro and some parts of the article soon if no objections. Tommy1441 (talk) 15:32, 31 July 2015 (UTC)[reply]
