Arum maculatum

From: grsjr at juno.com (George R Stilwell, Jr.) on 1997.10.24 at 01:32:40(1482)
Gene & Jan,
Peter Boyce doesn't list an Arum maculata in his book, nor have I heard
of it. Are you sure you
don't mean Arum maculatum? I believe hort. latin demands "um" for Arum
rather than "a".

Peter describes 34 different forms, ssp., etc of A. maculatum. Pandora
Sellars' beautiful
colored illustration follows page 48 (Plate 1).

Dear Folks
I saw Ray's email apropos A. maculatum/maculata and had to add that I
don'i describe 34 forms of maculatum; quite the opposite, I discarded
that many (more, infact) superfluous taxa!

Ray,
Thanks for the correction. Should have checked before sending the
message. No spell checker for Latin. I was, indeed referring to Arum
maculatUM. I have not seen the book by Peter, only have the 3 pages in
Deni Brown's book. Could you please post the full name of the book and
the author along with information for purchasing the book you are
referring to here?

Gene,
It took quite a while for interlibrary loan to come up with the book,
"The Genus Arum" by Peter Boyce (A Kew Magazine Monograph, The Royal
Botanic Gardens, Kew) but once I saw it I HAD to have it. You'll love
it. Informative and the illustrations are fantastic.

Dear folks,
The info on the book in question is--"The Genus Arum", by Peter Boyce,a Kew
Magazine Monograph, ISBN 0 11 250085 4, Copyright The Bentham-Moxon Trust,
Royal Botanic Gardens, Kew, 1993. 30 British Pounds. 196 pages, 16 color
illustrations, MANY line drawings, maps, etc.
This is a wonderfully done book, lots of great info, line drawings, and the
color illustrations are really works of art in the true sense of the word, and
by themselves are more than worth the price of this great book, in my opinion!
Cheers,
Julius

Peter Boyce or other Arumettes:
We are growing a number of arums, and are thoroughly confused with
Arum maculatum. None of the plants that we are growing as A. maculatum are
solid green or spotted black. They are all patterned with silver. Could I
assume that all of these are actually A. italicum or hybrids between the two.
Also, I got two specimens labeled A. maculatum 'Variegated' from
Pontzyfield Herb Nursery in Scottland. They appear to be classic heavily
silver patterened A. italicum except that they never went dormant this past
summer when all others died down. They still look great now...what is
happening?

Dear Tony;
My 2 cents.
It does seem like a lot of Arum maculatum in the US is either
mis-identified or not spotted. I had a lot of questions about this, too.
The true Arum maculatum is quite distinct (spotted or not) from A italicum
(marked or not). My spotted plants self sow with both spotted and unspotted
seedlings apppearing.
The plate of A. maculatum in Peter Boyce's wonderful book "The
Genus Arum" is a bit wierd in that it makes the black spots almost look
like 'sores'. In my plants there is a far simpler black (Dark brown) mark
more like that done with a permanent marker. The spots are scattered around
the leaf at random.
I have some seedlings named as hybrids that are washed with a
silvery pattern, but unlike that of A. italicum pictum. Still too young to
compare, but it seems these 2 must hybridize pretty readily and the hybrids
have some vigor!
A maculatum in flower is distinct!
Hope it was of some help. jim W.

Dear Tony
The really crucial question is when do your plants break growth. Arum
italicum emerges in late summer/early fall and remains in leaf
until latel June/July. Occasionally the new leaves will emerge while
a few tattered leaves of the previous season remain.
Arum maculatum emerges in winter to late winter (it's JUST beginning
to show in southern England) and is generally gone completely by late
May.
I've NEVER seen a truve A. maculatum with silver veining; always
either plain green or variously spotted. Your plants are probably
rither A. italicum ssp. italicum (which is HORRIBLY variable) or
hybrids between this and A. maculatum.

Pete:
Thanks...I think you have solved an identitiy problem for a lot of
us with "silver patterned A. maculatum".
