Hi Scott,

you could try my 'Feature Finder' template matching plugin - I have  
put it online now:
   http://imagejdocu.tudor.lu/doku.php?
id=plugin:analysis:feature_finder:start

It seems that the features of interest (trichomes) can appear  
differently, with or without the bright ring? So you might combine  
the results obtained with different templates (prototypes).
And there are lots of parameters to try: different brightness/
contrast of the template, different ROI size in the template, and all  
the parameters of the dialog box...

Michael
