Distributio

Planta in viginti ex viginti-sex Civitatum Foederatarum orientalium sterilitatibus serpentinis fit, quam ob causam flagship species^? huius oecosystematis unici appellata est. Ea olim putabatur in his sterilitatibus endemica, sed ea etiam in singula colonia disiuncta inter diabase glades^? in Carolina Septentrionali habitare nuper observata est.^[1]

Symphyotrichum depauperatum a civitate Pennsilvania species periclitata classificatur quia eius distributio in paucis regionibus finitis circumscribitur, et plurimae ex eius populationibus in sitibus ab excidiendo,^? auctu domuum,^? et auctu industriarum periclicatae fiunt.^[2]
