Close-lobed dandelion

Close-lobed dandelion refers to a microspecies within the extraordinarily diverse aggregate Taraxacum officinale sensu lato (family Asteraceae), the common dandelion complex. Dandelions are notoriously complex taxonomically due to widespread apomixis — asexual seed production without fertilization — which generates thousands of clonal microspecies that are morphologically distinguishable but reproductively isolated. Close-lobed forms are characterized by leaf lobes that are positioned closely together, with shorter spaces between the lobes than in more deeply divided or open-lobed morphs. This leaf morphology is one of dozens of characters — including lobe shape, involucre bract posture, achene color, and scape characteristics — used by Taraxacum specialists to delineate the hundreds or thousands of named microspecies. Dandelions of all morphologies are ecologically important as early-season nectar and pollen sources for bumblebees, honeybees, and numerous other pollinators. Their deep taproots break up compacted soils and bring nutrients from depth, and their seeds provide food for finches and other seed-eating birds across open habitats in temperate regions.
