Talk:Toxicodendron

message: Division of species as to whether they benefit or harm Man (Rhus vs Toxicodendron) has a long history in Antiquity and medieval lore, which predates Botany. This is an interesting vestige from the history of ideas that should be mentioned, if the false division is still to be insisted upon here in Wikipedia. --Wetman 11:08, 21 Mar 2005 (UTC)
thread_title: archaic classification

message: Why on earth are all of these names hyphenated? WP is the only place I've seen this done and I suspect it's just a holdover from very early drafts.  I'd like to move all the hyphenated articles to unhyphenated (e.g., "poison ivy", "western poison oak") unless someone has a really good reason why not. Nearly all refs to assorted pages are via redirects from the unhyphenated versions (e.g., see Poison-ivy (plant) What links here), which further demonstrates that the hyphenated version is incorrect.

text: I am fixing things but am stuck on Poison Ivy at the moment; technical difficulties mean I can't delete/move Poison-ivy there yet. But I'm changing hyphenation meanwhile.  Elf | Talk 02:04, 18 Apr 2005 (UTC)

text: But it's not *commonly* done. I did indeed find one book among my few that talk about poison oak or ivy (as a weed mostly) that hyphenates it, but the others don't. In the biology classes I took, they weren't hyphenated. Neither Webster's nor Encyclopedia Britannica hyphenate. The other counter-example you gave, ; the first three books I checked just to be sure I wasn't imagining things--Western Garden Book, the American Horticultural Society Encyclopedia of Garden Plants, and Northern California Gardening--not a hyphen to be seen.  These have always looked misspelled to me here in Wikipedia and they still do.  I don't think that anyone searching for them will spell them with a hyphen and--as I pointed out--no one referring to them outside of these three articles uses the hyphenated form.

replies: text: I agree that the hyphens are unnecessary and would add Hortus Third to the list of widely respected references that do not use hyphens.  Perhaps we need some kind of consensus on the Tree of Life page? WormRunner | Talk 16:26, 18 Apr 2005 (UTC)
replies: text: That's certainly not true about "douglas-fir is also never hyphenated", that is the standard orthography with both the USDA and the US Forest Service. It is all about avoiding confusion; I don't think we should be promoting botanical error and confusion in wikipedia. Or do you have some botanical evidence for its classification as Quercus diversilobum (Torr. & A.Gray) Elf? - MPF 17:03, 18 Apr 2005 (UTC)

text: Sure, I ran out into my back yard and did my own DNA analysis. :-)  No, really, I'm not arguing that the scientific names are incorrect. But I am thinking that common names are inherently not scientific names and trying to make them act like scientific names against common usage could possibly be more confusing.  Elf | Talk 18:51, 18 Apr 2005 (UTC)
replies: text: I can see the point you're making there in "common names are inherently not scientific names and trying to make them act like scientific names against common usage could possibly be more confusing", but would disagree in the validity of that analysis - I know of all to many examples from forums and discussion groups etc that using ambiguous vernacular names is far more confusing than getting the vernacular names to match the scientific. While some may think 'Poison-oak' looks odd, I don't think anyone would have trouble understanding that it is the same as what they've always preferred to call 'Poison Oak', whereas the converse cannot be taken for granted at all, there will certainly be people who think that 'poison oak' refers to a Quercus that happens to be poisonous. This is particularly likely in an international situation like wikipedia with many readers with no knowledge of Toxicodendron at all. The sad fact is that most people don't know or use scientific names; and the natural human trend is to treat vernacular names in the same manner as scientific names "X Oak and Y Oak are both called 'oak', therefore they are related". - MPF 19:44, 18 Apr 2005 (UTC)

text: I'm afraid that someone who'd be confused into thinking that something referred to as an "oak" is an oak isn't going to be set straight by the existence of a hyphen. Of course I understand that I'm apparently arguing against some larger set of botanists who do use this convention.  Still, as a technical writer who works with assorted experts on a regular basis, I know that they are not always right about the best way to communicate info. I, of course, am. ;-)  (Wait--I know that's going to come back to haunt me--)  OK, I'm going to go away now because I hate looking at something that looks misspelled and I'm going back to the Dog breeds project. You're welcome to come over there and point out that we have weird conventions for dog-related language any time--where people are often confused into thinking that something that's called a terrier is a terrier when in fact sometimes is isn't-- The horror!

text: A peanut is also not a nut, but a legume. By this token one should write "pea-nut". The common English spelling is "poison oak" and "Douglas fir". One might mention the use of the hyphen in certain scientific works as a technical term, but that doesn't change the way the vast majority of educated English speakers spell the words -- just as they will find it spelled in reference works dealing with language, not botany.Janko (talk) 07:27, 27 January 2010 (UTC)

text: LOL, always makes my day to see the Wikipedia control freaks try and use the venue as a means to change common usage. "Why must Webster always be right?" they say. (And 5 years later, every reputable dictionary still leaves off the hyphen -- but not Wikipedia.) This is a major reason why Wikipedia is not taken seriously by any serious researcher (i.e., unlike the dictionaries, Wikipedia is NOT reputable). If you want to add a (superfluous) section commenting on botanical hyphenation, fine -- but don't insist it is the ONLY correct usage in all contexts when, in fact, it is incorrect usage in most. 97.127.56.97 (talk) 15:24, 15 June 2010 (UTC)
thread_title: Hyphenation

message: I've lived in California for 31 years of my life, Connecticut for 6, and Chicago for 2. This article really looks to me like it was written by an Easterner. It implies that poison ivy is common in California, but I've never seen poison ivy in California in my life. It also makes it sound like poison ivy is common east of the Rockies, but if so, then "common" has to be interpreted completely differently than you'd interpret it if it was referring to poison oak in California. Basically all wild land in California is has poison oak. You can't go anywhere without encountering it. OTOH, I've never seen poison ivy in my life, anywhere in the U.S. I'm going to do some edits to try to make this a little more realistic.--Bcrowell 03:28, 13 August 2005 (UTC)
replies: text: I grew up in both CA and NY. I'd agree with you about poison ivy in CA, but at least in midstate New York it's just like poison oak is here--springs up everywhere.  I can't speak for other parts of the country. Elf | Talk 01:50, 16 August 2005 (UTC)
thread_title: no poison ivy in California; poison ivy not that common elsewhere

message: Nay I don't think people looking for an article on poison oak are going to want an article on the Toxicodendron genus. I think the current disambiguation page is the best bet. --Calibas 02:00, 11 December 2006 (UTC)
thread_title:  Merger 

message: "They have pinnately compound, alternate leaves and whitish or grayish drupes." <-- This sentence, that begins the third paragraph of this article is not true. Toxicodendron radicans leaves are generally trifoliolate, as stated in the Toxicodendron radicans article. This is stated in the uconn.edu article. Also, take a look at a Poison Ivy plant outside and you will probably see that it's trifoliolate. Therefore, this Toxicodendron genus article may be able to say that most Toxicodendron leaves are pinnately compound. I'm going to edit the article right now.  — Preceding unsigned comment added by Ericismyname (talk • contribs) 17:47, 23 September 2012 (UTC)
replies: text: While "pinnately compound" often includes plants with more than 3 leaflets, trifoliolate plants can also be considered pinnately compound. Legumes are often pinnately compound, but Trifolium has only 3 leaflets. Are clovers not pinnately compound? Pinnately compound/trifoliolate are not mutually exclusive.
