All orchids are mycoheterotrophes
editThe "ecology" section seems to imply that only the species of Orchidaceae that lack clorophyll are to be considered mycoheterotrophic, that's not the case. All orchids, at least as they germinate, are mycoheterotrophic, some lose the need to be as they grow (Orchis for example), others are mostly dependant on the symbiosis throughout their lives (most Cephalanthera), others are completely dependant, the latter being the category the article refers to. I'd change it myself but my english is not the best and I'm new to editing Wikipedia Cardocca (talk) 20:16, 24 May 2023 (UTC)
- Hello @Cardocca: I would be happy to add the statement "All orchids, at least as they germinate, are mycoheterotrophic...." if you would add a reference that I can access, here. Gderrin (talk) 21:35, 24 May 2023 (UTC)
- Thank you, this is freely accessible i believe. Cardocca (talk) 21:39, 6 June 2023 (UTC)
There are no saprophytic orchids
editAlthough old academic articles refer to some orchids as saprophytic, this is an obsolete term that should not be perpetuated in Wikipedia. There is no plant that directly consumes dead organic matter (saprophytic). Orchids are mycoheterotrophic. Some orchids depend on saprotrophic fungi. In these cases, the saprotrophic lifestyle is exercised by the fungus, not the plant.

Number of cultivars
editI've just made an edit removing the statement that horticulturalists have produced "more than 100,000" hybrids and cultivars. I noticed that the figure was only in the lead and not the article body, and unsourced.
I went digging in the page history and found the 100,000 figure was first added in 2005 with no source, by an IP user. Before that the number given was 60,000, which was included with no source in the very first version of the page in 2001, also by an IP user.
I haven't been able to find any trustworthy sources for an estimated number of orchid cultivars. Unfortunately because the 100,000 figure has been right at the top of the wikipedia page for so long, there are countless sources which clearly just referred to wikipedia in the first place, so we need to be really careful not to reintroduce the number with a circular citation.
The Royal Horticultural Society is the ICRA for orchids, and they do have an online database. But it's only searchable by genus or grex, there doesn't seem to be an unfiltered 'countable' version that's publicly accessible. I'll keep looking, but if anyone else has any leads please go ahead.

- If you stick Phalaenopsis into the RHS seed parentage search box you get 40,000 results; for Paphiopedilum 30,000; for Cymbidium 18,000; for Cattleya 40,000; for Dendrobium 17,000. "more than 100,000" seems very plausible, though there is potential scope for misinterpretation of the results. (Are false positives a possibility? Are synonyms included?)
- The blurbs for two editions of the Addenda to Sander's List, covering the 6 years 2014-2019, say that they include 20,000 hybrids. (I was looking to see if a number could be found in an Orchid Register Supplement or Orchid Review. The Reviews seem to be unavailable online, and the Supplements don't appear to give numbers.) Lavateraguy (talk) 12:43, 21 November 2024 (UTC)
- Thanks, good thinking. I don't doubt the number (I'm sure it's much more than 100,000), only the vagueness and lack of citation.
- Would summing the totals from those RHS searches to give an estimate be considered original research? I think synonyms are included in the listings but they'd only be a very small proportion. Averixus (talk) 17:55, 21 November 2024 (UTC)
- I believe that the relevant bits of policy are WP:SYN (a subset of WP:OR and WP:NOTSYNTH). Synthesis is defined as combining two different sources to draw a conclusion not explicitly made in either source. If one were to rules lawyer this, one could argue that the RHS Orchid Register is a single source. But WP:CALC is a better argument, or in extremity WP:IAR. It seems that summing the total from the RHS searches is acceptable; my concern is that the meaning of the returned numbers is not fully transparent. (For comparison the RHS Find a Plant database numbers are grossly inflated by synonyms.)
- If the Register Supplement had exact or approximate counts of new registers in each supplement adding up these numbers would be legitimate, but these numbers do not seem to be consistently provided, so one would be reduced to multiplying the number of pages by the (variable) number of entries per page Lavateraguy (talk) 21:24, 21 November 2024 (UTC)
- I wonder if it would actually be best to just give a sense of the rate new cultivars are being introduced, rather than the total number. The most recent sander's addendum (2017-2019) quotes "over 11,000" registrations in the blurb. Maybe a simple statement like "Several thousand new orchid cultivars are bred each year"?
