  Lysichiton Americanum Query
From: SNALICE at aol.com on 1997.08.05 at 14:30:49(1016)
Hello to everyone,

I sent the above questions to Greg Ruckert in hopes of finding some
answers to the Lysichiton seed collection I am attempting to make. Greg has
no personal experience with this species, but is hoping to hear from the list
too, as he will be recieving some of the seeds. He is sending me what
information he has via snail mail, and has suggested that I pose the
questions to the list. I believe the Lysichiton seeds that I bagged in the
field are very close to being ready to harvest, and may need immediate
attention. According to information from from one source, the seeds are only
viable for a short period of time. Here is the forwarding note I origianaly
sent to Greg:

Julius and Mike,

>>>>>One of the thoughts offered as to "why" Urospatha and other
Aroids have this substance surrounding the seeds is that perhaps it may
provide or attract moisture needed by the seed to germinate, much like the
gel

Dear Sue,
Since I haven`t actually seen the species in question, it is difficult to
offer a suggestion as to the reason for the form of the "gel body" you have
observed on the seed of Lysichiton. Any ideas from other members/lurkers
would be welcomed.
You may want to continue your observations on the infructesences` development
under natural conditions, to try to learn what the agents of distribution are;
they may be animals, birds or water. By doing so you may find a clue as to
the reason for the shape/form of these structures. So little is recorded
about these aspects of Aroids that it presents us with a great chance to
add to the knowledge of these interesting plants.
Keep up the good work.
Sincerely,
Julius

In some other species of plants (notably the genus Othonna) the gel produced
by the seed is thought to be a germination inhibitor--delaying germination
until the time is right.

Presumably this is when the rains are sufficient to wash away the gel--and
provide proper growth conditions for the seedlings that will result.

Given the habitat of Lysichiton I'm not certain the explanation suffices but
it's food for thought.
