(The use of these descriptive family names is less frequent than it used to be, but it's still legitimate.)

But Liliaceae and Scrophulariaceae still exist. For example the Angiosperm Phylogeny Group lumps Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae (as per Cronquist) into Malvaceae (but the new Heywood et al chops this into 12 families). Over history this group has been divided into as few as 2, or as many as 14 families. Several more distantly related groups were placed in Tiliaceae in the past. -- Stewart Robert Hinsley To name just a few that I can remember that I was brought up with: Graminae Umbelliferae Compositae Papillionaceae (and Leguminosae) Cruciferae ok, "half" is an exaggeration; it is "loads" though if you go through the common ones (ones with familiar native and garden species).- Hide quoted text - - Show quoted text - ok, to be fair, I have only managed to think of 2 more (Labiatae and Guttiferae) so it is not so many.

The original, and only realistic, point of standardised names is to improve clarity of communication, ESPECIALLY with people who are not obsessive botanical taxonomists. Encouraging alternative names is, at best, confusing. Even if there were a single name at any one time, it is SERIOUSLY confusing to be unable to identify a classification unless you know the precise version of the code that the author was using. And, when author A quotes an earlier publication of author B, there is no way to tell what the HELL is meant. If I understand section 18.4 correctly, this applies to Papilonaceae and Leguminosae, redoubled in spades and with knobs on - even now, at this instant in time. If you see a reference to one of those, is it a synonym for the Fabaceae or for the relevant half of it? That code has elevated a reasonable set of default rules to the status of Holy Dogma.

My personal gripe is a relatively minor one but I only recently realised that more or less half of the plant families that I used to know have been done away with. Some genius decided that you cannot have a plant family that is purely descriptive such as Leguminosae or Compositae; you have to name the family after one of its genera. In most cases it is not so hard seeing as the family names are easy to guess if the chosen genus is a familiar one and most are. I used to be a taxonomist a long time ago; glad I gave it up; it's a young man's game now :-).

See article 18.4 of the Vienna Code of the ICBN. http://ibot.sav.sk/icbn/main.htm -- Stewart Robert Hinsley I just meant family names that I was brought up with and that were very familiar and that have been changed (because they did not end in - aceae or were purely descriptive and did not refer to a particular genus). The names I listed were the ones I remembered because these are all very familiar names (I will never get used to things being in Apiaceae and not Umbelliferae if for no other reason than I refer informally to plants from that family as "umbellifers"). Those famiies are so familiar that I was shocked to see them changed and it felt like half the families I knew had been altered. It turns out to be only a few as I discovered when I tried to list them so I was getting carried away. Psychologically/emotionally these families seem to cover about half the plants that grow in my garden. |
