Incorrect stacking of map records
I mapped Cleistes bifaria. I then turned off the ambiguous records and saw several previously hidden unambiguous herbarium collection records appear. This should not be the case as the unambiguous collections should have highest priority. Further examiniation showed that the problem is with the ambiguous collections of Cleistes divaricata; if this is unchecked, then everything works correctly.

Well, no, not yet fixed. Perhaps Jeff failed to explain the problem clearly.
Consider Quercus alba. Robeson County NC is colored pink (ambiguous specimen record), but you click on it (or turn off the ambiguous records) and you see there are unambiguous RAB and USDA records covered by the pink. This is incorrect.
The proper stacking is
1. Red[NCU,NCSC,WEWO,X-ILL] > Orange[CPE,NCNHP] > Green[RAB,USDA] > Blue[CV]
2. All unambiguous records, regardless of source > all ambiguous records

Great! The stacking order is now correct.
However, let's also change the explanation. Reorder the colored key below to reflect the stacking order. Also, modify the text "Different colors stand for different types of data sources." to be followed by "When multiple records occur for a county, records are stacked in the order below with the color of the top record displayed on the map."
