Talk:Trillium grandiflorum

message: "for decades, Ontario schoolchildren were told that picking Trillums was illegal. This was never the case."
Besides the incorrect grammar, this contradicts Trillium: "...in many areas, e.g. British Columbia, Michigan, New York, Ontario, Oregon, and Washington, it is illegal to pick trilliums." No references in either case. So which one's right? - Shoryuken 10/09/05, 21:28 UTC
:all I know is that when a schoolchild in ontario I was told that picking trillums was illigal. A student picked one, but failed to be arrested... pretty flimsey evidence, but that's the extent of my knowledge on this case. Pellaken 22:39, 10 February 2006 (UTC)

message: The article says the large-flowered trillium is the state flower of Ohio, but the Ohio article says it's the scarlet carnation.  There seems to be a disagreement here. —The preceding unsigned comment was added by Schepler (talk • contribs) 23:19, 28 April 2007 (UTC)
replies: text: It's the state wild flower (with that spelling in the statute). The list needs to account for the cultivated/wild split that other states already have. Circeus (talk) 04:53, 24 April 2008 (UTC)
replies: text: I have also read that Trillium is the state flower of Michigan.  I do not know a reasonably certain way to research all state flowers, so i did not offer an actual edit, but Circeus, maybe you do know how to look this up?   Dan Timmel (talk) 16:17, 6 July 2009 (UTC)

thread_title:  State flower of Ohio? 

message: Perhaps it is my perspective as a botanist in training, but I think it's important that that bract and leaf issue be clarified. It's not so much a matter of the leaves being considered bracts, but rather they are bracts, and this is what gives the trilliums' foliage whorls such a distinctive look. They are different in a number of ways other than morphology. Leaves and bracts are regulated by different genes, for example. Petals, sepals, carpels and stamens are all modified leaves, but it would clearly be a misnomer to refer to any of them as leaves. So despite them being superficially similar to leaves, I personally feel it's important that they are referred to as bracts as soon as they are first mentioned, especially in the description section. ^_^ DJLayton4 (talk) 04:08, 24 April 2008 (UTC)
replies: text: Obviously I'm not versed enough in botany to quite understand the scope of the distinction (alas, I am but an amateur naturalist), but I think the word "leaves" needs to appear somewhere because otherwise it will confuse any reader not distinctly familiar with the technicals of "bract". Otherwise, I'll happily defer to whatever copyediting you want to subject my version to. Circeus (talk) 04:52, 24 April 2008 (UTC)
replies: text: Oh I agree that we can and should refer to them as leaves, I just meant that it was important that we clarify the distinction from the first mention. Everything's looking great by the way. Your speed is uncanny! ;P DJLayton4 (talk) 04:58, 24 April 2008 (UTC)

thread_title: Bracts vs. Leaves

message: * In the description, what does "they" refer to when it states "they persist after fruiting"? It was unclear to me when reading.
* Did I mess up any of the refs in the description or are they still referring to the right bits of information?
* In the ecology section, does the book referring to their preference for beech-maple forests say that this is in particular region or across the entire range. I believe many areas in the range don't have beech-maple forests.
* I'm going to break up the "Interaction with humans" section. Let me know if these changes looks ok.

replies: text: This sounds like a good idea to me. I used "cultivation and culture" just because other articles often have "cultivation" and "culture" sections, but since they would have been very short separately, I combined them. Feel free to change it back. ^-^ DJLayton4 (talk) 04:32, 25 April 2008 (UTC)
replies: text: Done adding/copyediting. It's just the header that looks weird, though I'd be quite challenged to find another formulation... Circeus (talk) 04:50, 25 April 2008 (UTC)

text: I am 95% sure its T. grandiflorum. First of all, T. pusillum is quite rare and is only found in areas south of Virginia, which is apparently nor where the Flickr user lives (though that's not to say he didn't visit, of course). Second, the leaves are, like you said, definitely indicative of T. grandiflorum and not T. pusillum. Third, I don't think petal width is a particularly good character for IDing them as it tends to vary, but the figure is 1.5–3 × 0.5–1.5 cm for T. pusillum and 4–7.5 × 2–4 cm for T. grandiflorum. It's hard to tell if they are 1.5 vs. 2 cm or 3 vs. 4 cm long, but to me the petals seem too big for T. pusillum. Given the the fact that the petal size almost overlaps between the two species, I think the leaves are the better character. Also, see the pink form here (T. pusillum is not in Connecticut).

replies: text: What it probably is is one senescing to the point where the petals are turning pink rather than a distinctly pink form.  DJLayton4 (talk) 21:00, 25 April 2008 (UTC)

message: Wow! This is a very well written article, and is obviously GA status. It's both accessible to the educated layman but still professional. Images, prose, grammar, broadness, and citations are all present. I really have nothing to suggest fixing other than explaining Reid's paradox a bit more.

I am in the process of uploading some older digital photos of mine and came across one of wild White Trillium. I am not sure of the cultivar (found in the wild at the base of a mountain next to a stream). Useful for the article? Tevonic (talk) 18:44, 6 April 2009 (UTC)
replies: text: Cultivars are not found in nature (if they were, they wouldn't be cultivars!). In fact, this is almost certainly a Trillium undulatum, not a T. grandiflorum. Circeus (talk) 20:07, 6 April 2009 (UTC)

message: I've started to edit the section on taxonomy. Further thoughts listed below. Comments welcome.
* T. grandiflorum f. roseum is not an accepted name so this paragraph may be moved. Moreover, the photo labeled as such is probably not of that form.
* The fact that variants of T. grandiflorum have green markings has nothing to do with taxonomy so this content may be moved.
* T. grandiflorum f. polymerum is not an accepted name and so the content on double-flowered forms may be moved.
* The comment on hybridization has nothing to do with taxonomy and so this content may be moved.
In the end, the section on taxonomy will be short or nonexistent. Tom Scavo (talk) 12:26, 18 August 2019 (UTC)
thread_title:  Taxonomy 

message: Michaux did not describe Trillium grandiflorum in 1803 (as claimed in the Taxonomy section). Rather he described a form of Trillium erectum local to the mountains of North Carolina. I claim it was Salisbury who first described Trillium grandiflorum in 1805. Tom Scavo (talk) 17:42, 2 November 2021 (UTC)
replies: text: according to IPNI, the basionym of Trillium grandiflorum is Trillium rhomboideum var. grandiflorum Michx. (1803); Salisbury elevated the variety to the species Trillium grandiflorum (Michx.) Salisb. (1805). The type of the species Trillium grandiflorum is the type of Trillium rhomboideum var. grandiflorum, and this was first described by Michaux. Conventionally, this is what is meant by "described" in botany – to describe a taxon only requires describing the type of the taxon. So it's correct to say: "Michaux first described the species in 1803 as the variety grandiflorum of Trillium rhomboideum (a species now regarded as a synonym of Trillium erectum var. erectum). It was raised to the rank of species in 1805 by Salisbury." Peter coxhead (talk) 18:40, 2 November 2021 (UTC)

text: You can argue that IPNI is wrong, but if so, you need to present its view, with the present IPNI refs, and then separately an alternative view with new refs, to maintain a neutral point of view. What I have put there now represents what the IPNI entries say. Peter coxhead (talk) 19:01, 2 November 2021 (UTC)
replies: text:  There are two names in the IPNI database: Trillium grandiflorum  and Trillium grandiflorum  You seem to be basing your taxonomical argument on the former but note that there is no link to POWO on that IPNI page. Only the latter IPNI page links out to POWO, and POWO likewise links to the latter IPNI page. However, POWO still displays the former name, and so it seems as though POWO is making a transition from Trillium grandiflorum  to Trillium grandiflorum . Tom Scavo (talk) 21:26, 2 November 2021 (UTC)

text: UPDATE: I just received an email from the POWO editors suggesting the IPNI entries are incorrect. In the email, the editors cited the USDA PLANTS database as authoritative. Tom Scavo (talk) 10:55, 3 November 2021 (UTC)
replies: text:  so the USDA entry has "(Michx.) Salisb.", agreeing with IPNI's main entry. There are many entries in PoWO and IPNI that differ in details of the authorities. IPNI also has many cases of multiple entries for the same name with slightly different details, because it has obtained them from different sources. In my experience PoWO is more often right than IPNI when they disagree, but we need a source that explains why "(Michx.) Salisb." might be incorrect. Peter coxhead (talk) 13:25, 3 November 2021 (UTC)

text: UPDATE: Last night the IPNI editors made a breaking change: Trillium grandiflorum  (such that Trillium grandiflorum  no longer exists in the IPNI database). I edited the main article to reflect this change. Tom Scavo (talk) 12:43, 4 November 2021 (UTC)
