[Taxacom] Herbarium sequence revisited

[Karen Wilson]

Agreed! I find the systematic arrangement very useful in herbaria.

For your information, Alex and others, David Mabberley is currently
finalising a new edition of 'The Plant-Book'. In it, he is planning to
use a slightly modified APG classification - modified after extensive
discussions with other botanists, individually and in informal workshops
here, in the Netherlands, the UK and USA over the past few years. 
In the context of arrangement of a herbarium, the Plant-Book is
equivalent to Dalla-Torre et Harms because it assigns all genera to
families, using a systematic classification. (Of course, it's much more
than D-T&H because of all the information given about each genus and
family.)
I know of a few herbaria that are using the last edition of 'The
Plant-Book' to arrange their specimens, and I imagine there will be more
using the new edition because of the change in classification. 

Cheers
Karen W.

Of course, this brings up another point.  It's easier to find something
alphabetically IF YOU KNOW WHAT YOU'RE LOOKING FOR.  Writing as an
arthropod specialist, especially one who deals with amateurs on a
regular basis, I find it is often easier for someone TO IDENTIFY AN
UNKNOWN by looking through a collection that is arranged
phylogenetically, the net effect of which is that related taxa that are
similar in appearance are frequently stored close together.  Many times
an identification can be made faster this way than by struggling through
a sequence of family, genus, and/or species keys.  The success of this
method certainly depends on the group, and it may not work as well for
plants, I don't know.

It depends on how people are going to be using it.  There's no question 
that it's easier to find things if they're arranged alphabetically.  
This is especially the case for non-botanists, since orders of plants 
(unlike insects) are not obvious to the casual observer.  Thus, if 
people are working mostly within a family or in only a couple, then it 
makes more sense to put the families in alphabetical order and post the 
phylogeny on the wall.  However, if people are mostly doing work among 
larger groups - i.e., multiple related families at once - then it makes 
more sense to put them phylogenetically, or at least alphabetically by 
order, and post an alphabetic listing of families on the wall.
