Sadly I too never got to meet this late great individual in person. He was a total inspiration to me since I first discovered the IAS. His personal contact list lead me to Julius Boos and onto other aroid enthusiasts across the globe. These two total gentlemen helped me - a stranger - as thoughthey knew me already. That was so profoundly moving on my part it is hard to accept they both are now no longer among us.

The IAS I do hope has among its members willing and able individuals to carry the Society forward from this really low point and run it for the future as a legacy to these two outstanding individuals.

Somewhere on the planet there must be aroids yet to be found that deserve to be named after these two late great IAS members.

I am shocked too. Though I am a lurker on this list (and on his exotic
plants forum), I  always enjoyed reading his posts and respected his efforts
to spread the scientific nomenclature and information through his website
and many other forums. It is the first time when the death of someone who I
haven't known determines my mood in my offline life.

Dear Beth,

Aloha.

Could you inform the other forums you post online?  UBC Forums, Araceae, etc?
Photopro is known to many people online....I do not know all the forums, but, I
know you like to post on a few. 

Aloha,

Leland

Wow, I'm floored.  Steve was such a tough, stubborn cookie that I think we all
figured he'd be around forever.  He's the reason I even got interested in aroids
and joined the IAS.  He will be sorely missed here.

Jude - I've got what I think is a new species of Anthurium, and one that Steve
really liked to boot.  If I can get a confirmation on its lack of description,
I'll be naming it for him.  I'll try to get seeds as well next time I'm up where
it grows, and if they're viable, I'll send them on.

That plant looks exactly like one of my Agaves, but the bloody tag has

I received this news late, having just returned from a week away/ offline. I am very sad to hear this. Unfortunately I have never had the pleasure of meeting Steve in person, but have had many personal correspondences with him. He was such a warm and welcoming person. This is a big loss to the society. My thoughts are with his family.


What a shock.

David,

I have no idea whether or not individual Pistia hairs are coated with
some form of wax or whether the wetting by water of an individual hair
is simply poor enough to provide a bridge for the droplet surface over
to the next surface hair, which bridging prevents wicking of the water
down into the hairy structure.

This would be a good research topic: Dry some Pistia leaves and see
what is extracted (meaning dissolved by some liquid, ordinarily
followed by gentle drying to investigate the residual - Steve Lucas
was right to insist on technical terms being defined) by solvent
(hexane or toluene would be good solvent candidates for wax) and if it
is indeed a waxy substance. If no one has done this I'll do it myself
and report back to this forum.

Another thing that might be of interest to aroiders is that the net
result of Pistia hydrophobicity (which merely means its reluctance to
be wetted by water, typically observed as a tendency for water on a
hydrophobic surface to "bead up" into discrete droplets) is the
extreme buoyancy of the species. Try to submerge one of these plants
and it's almost like you are trying to submerge an air bubble. It is
curious to me how insubstantial a Pistia leaf is. It looks big, but
when compacted and dried there is almost nothing left. Much of the
apparent volume is simply air.

Genevi?ve,

The lotus effect is quite common in my experience. It has been getting
a lot of attention in the popular press lately and there are a number
of academic studies of the phenomenon using nano materials. A Google
search will turn up many hits.

One of the best displays can be seen on the humble aroid Pistia.
Leaves of Pistia will support quite a large water droplet with no
wetting of the leaf surface that supports the hairs.

Hi Ted,

Pistia is in fact a very beautiful example for a water-repellent surface. It has to be kept in mind - as you mention - that it generates this superhydrophobic effect with hairs (not with papillate cells like in Nelumbo or Colocasia) that are covered with wax. So, the term 'lotus-effect' describes the syndrom of superhydrophobicity (which means that the contact angle of a water droplet is at least 150?), but there are different structures within the Araceae and other plant families, that produce this effect.
