  aroid hybrid
From: Tony Avent <tony at plantdelights.com> on 2009.08.09 at 17:44:12(19670)

Has anyone had experiences with Pinellia hybridizing with Sauromatum?
I know all my taxonomist friends are either reaching for a stiff drink
or headache medicine at the thought of such a hybrid. I'm not even sure
if this is even theoretically possible, but to be sure, we never let our
plants read genetics books. Take a look at our hybrid of Pinellia
pedatisecta and Sauromatum venosum. The height is 2' tall and, the
leaves are intermediate between the two parents. The plant produces
sauromatum like speckled petioles, but with many emerging per corm
(sauromatum only produces one each) like the pinellia parent. I missed
the flower this year, but will watch closer next year. I'd like to hear
your thoughts. http://www.plantdelights.com/gallery/Aroids

Dear Tony,

I have experienced Sauromatum with 2 leaves, and maybe seedlings can have even more leaves when they are in growth (I'm not sure, I have never raised Sauromatum from seeds), anyway very interesting plant. Good luck! If this Pinellia × Sauromatum hybrid is true you are writnig history!

Ah! The wonders of photoshop! Looks VERY convincing.

Joking aside, I think we aroid folks tend to think that 'our' plants don't
get up to such hedonistic sexual activities as 'other' groups, and thus
remain pure. While aroids in the wild do indeed very rarely hybridize the
evidence we have here in Asia is that is not so much a matter of pollen
incompatibility but rather niche partitioning, with different species
utilizing different guilds of pollinators (e.g., diurnal beetles;
crepuscular beetles; nocturnal beetles, etc.).

Tony very interesting to hear this. I would have never thought that that
cross would have been possible. Was this hybrid done at the nursery or
was the plants found in the wild? Personally I find this info extremely
exciting and interesting. I am sure others are feeling a bit sick or
whipping tears from their face. Either way I am sure we would all be
interested in seeing a flower of such a cross. Thanks.

Will be very interesting to see the flower. My only hope is that the hybrid
is not as prolific as P. pedatisecta, whose seeds seem to have a germination
rate of 110% and seem intent upon taking over my garden. I have had a
Saoromatum survive once over a relatively mild winter here, so perhaps if
this is a true hybrid, it will be a little less invasive.

You've successfully made an intergeneric cross.
Now let's think about the new genus name according to the botanical
I suggest:
× Sauronellia (if the genus Sauromatum will be back) or ×Typhonellia if
venosum will stay in Typhonium.
What do you think?

Thanks for the comments on our possible hybrid. As for juvenility, the
hybrid is over 4 years old...notice that it's already formed mature

Hi Jan,

Sauromatum/Typhonium venosum even with 3 leaves is nothing strange. If the growth period is long and good conditions, it can look like this:

I would have to agree that I have dug up many tubers of T. venosum with
multiple petioles after a good growing season so this is not deterministic.
It will be interesting to see the influorescence next year. I'm not a fan
of crosses in general, but an intergeneric is exciting if true :o) Dan

looks like small Sauromatums grown in some combination of lower light, richer soil, crowding. My venosum "volunteers" regularly produce multiple leaf stems. I'd wait till I see the flowers for sure. Can't seem to get rid of Pinellia pedatisecta here either...hmmm...maybe I've got hybrid offspring getting ready to take over Cliffwood Beach!

I think my suggestions are more elegant and easy to remember.
Anyway, I don't remember all the rules of intergeneric hybrid nomenclature,
Should the mother plant be first, does it matter?
In Orchidaceae there are names composed from 3 parent plants like
and I don't know if it is important from which genus the seeds were

The Code doesn't specify which parent comes first in the name of a
bigeneric hybrid, but the standard in all breeding is to put the
maternal parent first.
