Thanks for all the very informative help - yes, I now see the problems
inherent in using xlink:title as that has a wholly different intended
usage. I also realize that I am coding to the quirks of a particular
browser - FireFox. At the same time, going back and adding <desc> or
<title> elements for hundreds of plants feels like overkill and a heck
of a lot more work for a hand coder. I must admit that I do not know
about SVGT1.2 and declarative animation. I have to imagine that it
requires more work than using <desc>. I almost feel I need an attribute
tooltip="Clerodendrum inerme" that would function like the title
attribute on the HTML image element, just a simple way to pop up tool
tip with the name of the plant at that location - whether hovered by a
mouse or "selected" via the tab key.

Separately, FireFox renders title="" attribute on a shape element as a
tooltip even without the xlink prefix. I expect that this is a bug as
well. I would note Opera ignores both the xlink:title and title
attribute when used in a shape element such as circle. As long as
FireFox will eventually render the <desc> tag as a tooltip for the two
circles in code such as:

<g fill="violet" stroke="darkmagenta" stroke-width="1px">
  <desc>Clerodendrum inerme (ilau)</desc>
  <circle cx="6970" cy="-5950" r="2"  />
  <circle cx="6960" cy="-5950" r="2"  />
</g>

then I will not have to write:

<g fill="violet" stroke="darkmagenta" stroke-width="1px">
  <desc>Clerodendrum inerme (ilau)</desc>
  <circle xlink:title="Clerodendrum inerme (ilau)" cx="6970" cy="-5950"
r="2"  />
  <circle xlink:title="Clerodendrum inerme (ilau)" cx="6960" cy="-5950"
r="2"  />
</g>

Again, my thanks for the learnings.
