Taraxacum paludosiforme Doll (1978: 633 , Plate LXXII), described as a member of T. sect. Alpina

Type indication:—“Typus: Holotypus im h Doll / Locus typicus: Borovez, Flachmoor, ca. 2000 m. 12. 7. 76. Doll“; also Plate LXXII: „ Taraxacum paludosiforme Doll sp. nov. – Holotypus ”.

Type :— Flora von Bulgarien, Rila-Gebirge , Sitnjakow-Hütte – Mussala , Flachmoor , 12 Jul [19]76, R. Doll [as Taraxacum paludosiforme sp. nov. Holotypus!] ( JE, no. det. 19063, upper specimen, lectotype, designated here) .

Specimens of the OM:—The OM consists of a single rich gathering, mounted on four herbarium sheets. Although the whole gathering may be homogeneous taxonomically, there are several plants that cannot be interpreted (incomplete, not well preserved). The sheet I bears two plants photographed on Plate LXXII, the upper of them is designated as the lectotype; it is polliniferous, with a perfectly regular pollen. The lower plant on Sheet I is an isolectotype (JE, no. det. 36143). Sheet II, with one flowering and two fruiting plants (pollen abundant, regular in size). Sheet III, again with one flowering and two fruiting plants (pollen abundant, regular in size). Sheet IV, with three fruiting plants.

Conclusion:—The majority of plants of the type gathering of T. paludosiforme belong to a single species, a widespread diploid sexual, referred to T. sect. Crocea in the present paper. It is a variable taxon (see also the text in the special part of this paper below). We sampled it at very numerous localities, both in the subalpine and alpine belts in the Rila and the Pirin Mts., and it locally represents a Taraxacum dominant there. This taxon appears under several names in Doll (1978): T. paludosiforme (erroneously reported as a non-polliniferous tetraploid by Doll), T. pseudovernelense (again erroneously reported as a non-polliniferous tetraploid but having abundant, perfectly regular pollen), here relegated to the synonymy of T. paludosiforme ; an accepted name, T. carinthiacum (reported to be a triploid but having a perfectly regular pollen), and T. helveticum (correctly annotated as having regular pollen but reported to be both diploid and tetraploid; the gathering consists of a mixture of two diploids, T. bulgaricum and T. paludosiforme ).
