Taraxacum erythrospermum Andrz. ex Besser[FNA19, HC2]
red-seeded dandelion

Publication: Enum. Pl. 75. 1822.

Origin: Introduced from Eurasia

selected vouchers: WTU

Notes: FNA19: "Early leaves of Taraxacum erythrospermum sometimes may be broadly winged along the midvein, making distinction from T. officinale difficult; usually, its later leaves become more deeply lobed with time.
The name Taraxacum laevigatum has been used for L. erythrospermum in North America, following H. Handel-Mazzetti (1907). L. H. Shinners (1949) questioned that usage. The name is listed in the index of Flora Europaea (A. J. Richards and P. D. Sell 1973) as an unassigned synonym; it could be related to three different entities of sect. Spectabilia. And, it is not mentioned by other modern students of the group. Therefore, (1) given that the North American entity has not been identified with a particular Eurasian taxon; (2) to avoid using a microspecies name such as T. scanicum; and (3) despite the lack of typification of the name, I am using T. erythrospermum as a place holder until nomenclatural issues are resolved. This clearly associates the taxon with the section to which it belongs."
