Re: [Aroid-l] Steve Lucas and Julius Boos

From: Scott Radford <s.rad4d at ymail.com> on 2011.01.18 at 17:14:41(21764) 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 ac ross the globe. These two total gentlemen helped me - a stranger - as th oughthey 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 Soc iety forward from this really low point and run it for the future as a l egacy to these two outstanding individuals. Somewhere on the planet th ere must be aroids yet to be found that deserve to be named after these two late great IAS members. ________________________________ From:"aroid-l-request@www.gizmoworks.com" www.gizmoworks.com> To:aroid -l@www.gizmoworks.com Sent: Tue, 18 January, 2011 5:46:28 Subject: Aroi d-L Digest, Vol 78, Issue 14 Send Aroid-L mailing list submissions to aroid-l@www.gizmoworks.com To subscribe or unsubscribe via the World Wide Web, visit http://www.gizmoworks.com/mailman/listinfo/aroi d-l or, via email, send a message with subject or body 'help' to ar oid-l-request@www.gizmoworks.com You can reach the person managing the list at aroid-l-owner@www.gizmoworks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Aroid -L digest..."

This would be a good researc h topic: Dry some Pistia leaves and see what is extracted (meaning dissol ved by some liquid, ordinarily followed by gentle drying to investigate t he residual - Steve Lucas was right to insist on technical terms being de fined) 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 hydrophobici ty (which merely means its reluctance to be wetted by water, typically ob served as a tendency for water on a hydrophobic surface to "bead up" into discrete droplets) is the extreme buoyancy of the species. Try to submer ge 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 l ooks big, but when compacted and dried there is almost nothing left. Much of the apparent volume is simply air. Ted Held Detroit.
