Thanks LariAnn. That's very useful information. Some greater flexibility in data fields will be necessary to accommodate the variable habits you note. If scandent and recumbent were both checked for Bob See, perhaps an "Other" check box which opens up a write box would work? A short explanation could go there. The write box should be useful to explain how tree types can vine as well.
We can have a (very) short definition of a data point, a scroll-over, that would be useful for "Short-stemmed". Something like Short internodes. Self heading, Self-header or something to that effect?
