Below is a message from the fern list (fernet) which I thought would be
of interest to cacti_etc subscribers (perhaps more to the 'etc' segment).
The author, Robin Halley, also wrote to me that she or David Schwartz
would be willing to supply spores when possible. Some of these might make
interesting additions to the Seed Depot.
Does anyone on cacti_etc know of other ferns or fern relatives which
are succulent or otherwise xerophytically adapted? One that comes to mind
for me is a Selaginella species which shrivels when it dries out
(Polypodium polypodioides, the resurrection fern, also does this, but it's
not found in areas which I would consider primarily suited for
xerophytes.)
I should also point out here, for those who might be interested, that
the American Fern Society has a spore exchange for AFS members:

Nick:
Sometime back, I asked the same sort of a question, although it is
in regards to a fern some consider to be a true succulent. Apparenty no
one on this list knew anything about it. It is very rare, and exists in
pumice rubble from volcanos in 4 known areas of Southern Oregon, and
Northern California. Even though it has 4 known habitats, there are very
few plants in each. The name is Botrychium pumicloa, (Ophioglossaceae),,
the "common" names are Oregon grape-fern, or Pumice grape-fern.
My question was, and still is, is it possible for the designation of
succulent to be applied to a so called lower plant form?
This plant is not a halophyte.
It is soft green in color, glaucous, and has a thickend stem, and
rounded fleshey leaves with notches, with round fruiting bodies lined on
the top edges of the upper leaves. It grows to around 6 inches in height,
with a stought stem half the length, and ends in fronds, ( thats leaves
for those of you in Rio Linda).

I a message just about two weeks ago regarding xeriphytic ferns. The ones
that grow in the Sonoran Desert, the ones I know at least, don't quite
meet the standards for being a "succulent" although the foliage on many of
these tough plants are quite leathery, sometimes almost plastic-like. The
problem is that they are hard to transplant and propogate and I am not a
fern expert although I am very interested in learning how to propogate
them. If someone can give me some info on this subject, maybe some good
references, whatever, I will try to get them into the trade, for I am very
interested in doing so. I have a nursery but I may not have the resources
to propogate ferns as I have heard that it is quite difficult. I am
willing to take the challenge with some assistance. Does anyone in AZ have
experience, especially Tucson?

I'm just catching up on recent Cacti_etc postings and was interested in
the discussion on succulent & xerophytic ferns. Two genera that have
enlarged, succulent rhizomes are Lecanopteris 'ant fern' (tropical Asia)
and Solenopteris 'potato fern' (Costa Rica & northern S. America). In
both cases ants live in the hollow cavities of the rhizome. There is a
marvellous photo of the caudiciform-like rhizome of Lecanopteris carnosa
in the book by Camus, Jermy & Thomas (1991: p. 38) entitled 'A World of
Ferns'. Another useful reference on ant-plant associations is: C. Huxley
(1980), Symbiosis between ants and epiphytes. Biol. Rev. 55: 321-340.
Both fern genera are mentioned and illustrated in the paper as are
Dischidia, Hydnophytum and Myrmecodia, 3 genera that are occasionally
grown by succulent enthusiasts.
If anybody on the list knows of a source of Lecanopteris or Solenopteris
please let me know as I would like to have living specimens of these for a
course I teach on ferns and fern allies (the spore-bearing vascular
plants).
HTH,
Mike
