It seems that the DNA data places Celtis and allies, hence Celtidaceae,
as distinct from Ulmaceae,

Who are these allies?

+ + +
By and large, the former subfamily Celtidoideae
The APG has a list that you can click on (from Kew).
Obviously Pteroceltis, but also Trema and Gironniera. Parasponia. Note that
Kew does not include Aphananthe and Lozanella, but the APG site does.
Exclude Ampelocera.

Nice touch, the "who"!

Good grief! I never heard of any of these. Are they tropical species? Are they
good for anything?

Well, it is just like with Celtis, most are tropical, some temperate.
I would have thought Trema to be fairly well known.
It is pretty widely planted in the tropics.
Pteroceltis is only the one species, from China.
Gironniera has a handful of species in Asia: it crops up from time to time,
as does Aphananthe

I must admit never to have heard of Parasponia either, or Lozanella

I hate to be a pedantic curmudgeon, but I have ample evidence just from
Iris's "signature" that her whole point of view of Kingdom Plantae is from
that of a gardener where everything must have a "use". I have a very
different point of view. Many years ago in Forestry School, I had a textbook
called "Design With Nature" by Ian McHarg. He has a line that has stuck with
me through the years, and done me very well: "That which is is. It is
justified only by being." Not everything must be "useful" by mere human
standards. But many of these "useless" plants have proven to be very
"useful" in unveiling the tree of life. Often it takes long study to
determine what is "useful". Garden plants are just one of a wide variety of
"uses".

Oh good grief! I forgot that on the Internet there is always someone who can't
tell when you're joking. Actually, I looked up a picture of Ptericeltis and
found that it has very attractive peeling bark. However, I am quite certain
that the only use for Welwitschia, Fouquieria columnaris, or Masdevallia
caudivolvula, is to laugh at, which is very important nowadays.
You know what poison ivy is good for, don't you? It is to keep idiots who don't
belong there out of the woods.
