Thanks Kouta, it'll be interesting to see the consensus there.
For clarification for anyone who doesn't understand bbeduhn's comment 'it is not one of the "true" hickories', the hickory genus Carya is divided into two subgenera, the pecans (Cc. illinoinensis, cordiformis, aquatica, myristiciformis), and the true hickories (Cc. ovata, laciniosa, tomentosa, glabra, etc.).

Ik heb vandaag een acer rubrum geregistreerd. Rot-Ahorn (Acer rubrum) '19478' met een afmeting van 2,78 m op 0,90 cm is het een respectabele boom. Als ik de lijst van Acer rubrums zie blijkt deze boom niet serieus genomen te worden. De door mij gedane meting komt niet tevoorschijn en de boom telt kennelijk niet mee. Dit verbaast me. Het is zeker geen meerstammige boom. Hij vertakt op 90 cm maar dat betekent niet dat hij meerstammig is, waarom verschijnt hij dan niet in de normale lijstjes.? Erg onbevredigend.
Heeft Tim toch eerder uitgelegd: de bomen verschijnen pas na enige tijd in de lijstjes, waardoor het totale systeem minder traag is geworden. Jouw esdoorn zal binnen enkele dagen in de lijsten verschijnen.
Maybe the non-standard measuring height of 0.9 m excludes it from the 'stoutest' table? Just like multiple stems affects the 'true' girth of a tree, so does measurement at other than 1.3-1.5 m. I am guessing those two low branches are the reason for the 0.9 m measurement. Did you also measure the girth above those branches?
On the Tree Register, we distinguish 'B' class trees, where the trunk can't be measured at the standard 1.5m but the measured girth is not significantly inflated by forks etc, from 'C' class trees, which do fork and where the measured girth can't be meaningfully compared with clean-boled trees. 'B' class trees can become girth-champions, while 'C' class trees only appear as alternative champions or as champions when the girth is very much bigger than any others.
On Monumental Trees, the distinction can also be made by answering yes/no to 'does the tree have multiple stems'. But I have noticed that some recorders (eg Red Rob) are answering 'yes' to this in the case of trees that fork higher up in their crown (and where the fork doesn't affect the girth, except that the crown will be broader and might power faster growth).
From their apparent youth, and location within a FC planted forest, I wonder if these are hybrids (Larix x marschlinsii), but I can't tell for certain from this photo. Larches are easily identified from the old cones which always lie underneath them - did you look?
For Tree Register purposes, I shall plump for Hybrid Larch as I suspect that true Japanese Larch is rare in FC plantings (while the hybrids are often back-crosses and quite close to Japanese Larch). As such this will be another UK and Ireland height champion. At this rate you'll soon have a clean sweep, Rob.
on the "all species" page and on the page of each separate species (example) there used to be non-clickable lists of its cultivars, varieties, subspecies, ... Now these links are clickable and counts are shown.
added rudimentary variety pages on which you see some information (photos, ...)
- changed the display of subspecies, varieties, forma, cultivars, and cultivar groups per Conifer's suggestion
Addenum: the text on specimen pages still needs a bit of tidying, e.g. here it says "The tree is a specimen of the cultivar 'nigra'", whereas it should say "The tree is a specimen of the subspecies nigra".
I will first add the possibility to rename the cultivars/..., change their type, and to delete them (it is already possible for a long time to create them, and to assign trees and reassign these trees).
Once the missing functionality is there, I will give the possibility to a restricted number of users to collaborate, agree on standards and to tidy up the cultivar list. I will post it here once the site's up to it.

When I press on 'Show on Map' the Google Map is close with individual trees visible. Press to change the location the map has panned out and I cannot get it to zoom in, I have to just stick a red bubble. Conifers, would you be able to put this directly in front of the 65 metre tree.
A technical point: as these trees are seed-grown (self-sown), they are Fagus sylvatica f. tortuosa, and not the cultivar 'Suenteliensis', which to be true to name can only be propagated clonally by grafting.

Thanks for this. You are absolutely right; this is the naturaly occuring forma tortuosa. I had the same type of discussion with Fagus sylvatica 'Asplenifolia'.or 'Laciniata'. This leafform also occurs naturaly and has been grafted under a few different names.
Thanks, that's true, it's not a clone. I changed name. New problem: I cannot get a small "f" before tortuosa. The system automatically generates a capital F. Will ask Tim to change it. But what must we think about the oak, MT nr. 18706? :)

Thanks! A bit of clarification though, re "I also made it so that cultivars/varieties always get a capital letter (as was the case), but subspecies don't".
The ranks of subspecies, variety and forma are botanical, and governed by the International Code of Botanical Nomenclature; they are always in italics and begin with a lower case letter, and must always show an indication of which rank is being used (the rank NOT in italics!):
Pinus nigra subsp. salzmannii
Pinus sylvestris var. hamata
Fagus sylvatica f. tortuosa
Cultivars, and cultivar groups, are governed by the International Code for Nomenclature of Cultivated Plants; they are not in italics, and begin with a capital; individual cultivars are in single quotes, groups of similar cultivars not in quotes:
