Subject: Trout lily pollen colour I am a postdoctoral fellow at the University of Ottawa (Canada), and am curious about the functional significance (if any) of the yellow-to-red pollen colour polymorphism that occurs in American trout lily (Erythronium americanum).
As a first step, I’d like to document pollen colour frequencies across the species range. If you are out admiring the spring ephemerals of northeastern North America this year, please consider taking a closer look at the trout lilies, and submitting your observations to: troutlilysurvey.wordpress.com <http://troutlilysurvey.wordpress.com/> Many thanks in advance for your help. Please share this message with others who may be interested. Sincerely, Emily Austen (http://emilyjausten.wordpress.com/ <http://emilyjausten.wordpress.com/>)
