A medium-sized dandelion with ascending lanceolate leaves. Petioles narrowly winged, white, but mid-ribs above often coloured darker and interlobes blotched blackish. Leaf side- lobes 3-5, subdeltoid, patent to slightly recurved, often interspersed with a single large tooth. Leaf end-lobe triangular, more or less homophyllous, but somewhat increasing in size on inner leaves. Exterior bracts pale greyish above, often becoming suffused purple later, rather broad, unbordered, slightly recurved. Capitula about 40-45 mm diameter. Easily confused with Maculata-group species such as T. longisquameum and T. scotiniforme, but with white petioles.
