There are now two free Android phone apps, one for flower

They're tiny apps, based on my (fairly popular) ID programs on the
web, e.g.: http://www.realtimerendering.com/flowers/flowers.html.

It strikes me that the Q&A stuff on your site might be improved upon:

* use AJAX to incrementally build the query (rather than
presenting one large mess of questions at a time). You could grey out
options which don't apply based on answers given to other questions.

When in bloom: add "NOW" and use the present date. Chances
are, if someone is trying to identify something they're looking at, it
may be currently in bloom.

Whether or not it is known that the plant has roots or a bulb.

sizes could be expressed in metric as well.

Also note that the diagram links for "Leaf veins", "Leaf edges", and
"Leaf Petiole" all come up with a forbidden on the other site you're
linking to.
