The fruits look like Taxodium distichum?

Fruits as If I was meant to say cones. I apologize for my lack of botanical knowledge and english as a second language.

vngarden is nearly there - it's a Pondcypress Taxodium ascendens (a.k.a. Taxodium distichum var. imbricatum).

Who is more authoritative on taxonomy? I usually get different responses from the Plant Lists and plants.usda.gov.

Now there's a question. plantlist.org takes it's results from various other databases listed on the right side in the results. It also rates the results as a "Confidence Level" based on return results. Low confidence means you need to dig deeper. The USDA is a fairly good database but sometimes not as up-to-date as it should be. I like to check http://www.tropicos.org/ first for plants of the Americas as I can trace back where it was published and by whom http://www.tropicos.org/Name/31300007?tab=acceptednames - I then go off and check the 2 you mentioned to see if they concur. There's also http://www.ipni.org/ipni/plantnamesearchpage.do , http://apps.rhs.org.uk/horticulturaldatabase/ and then I sometimes want to see what it is listed by in botanical gardens: http://rbg-web2.rbge.org.uk/multisite/multisite3.php . I sometimes also check http://www.ars-grin.gov/cgi-bin/npgs/html/tax_search.pl but, for some strange reason, it sometimes doesn't agree with the USDA database, although you'd think it would. Don't know if I answered your question.

Thanks for the links. Sometimes I am getting conflicting responses from various sources and I don't know which one is outdated or stay current.

I liken it to an audit trail and you're with the tax department doing a forensic audit. Find out who, what, where, when and then figure out why it's different. I'm sure I missed several databases to check.

In this case, it's a matter of opinion, not up-to-date-ness. Some people consider that Baldcypress and Pondcypress are sufficiently distinct to count as separate species, other people say they are too similar to each other to count as separate species. There's no right or wrong answer to this one.

My personal preference is to treat them as different species, but it's a very close call.

Dave's Garden uses both USDA GRIN and Kew (The Plant List) as naming authorities.

USDA Plants is a good reference, but often is not as updated as USDA GRIN.

It is best when both GRIN and Kew are in agreement, but if not, the authority with the more updated information is chosen.
