paginated pp. 9–44, and bound as part of the journal; its date is identical to that of the journal volume.]

Note: Bortiri‘s species concepts (1997) are much broader than most and were clearly not followed by
Tremetsberger et al. (2006).
Key to species (modified from Urtubey et al., 2009)
1. Capitula solitary (sessile or pedicellate, pedicels shorter than leaves); ligules equalling
phyllaries 2
Capitula several, in corymbiform cymes; ligules conspicuously exceeding phyllaries 8
2. Outer phyllaries broadly ovate; achenes rostrate, [proximally scaly] H. acaulis
Outer phyllaries usually longer than wide; achenes beakless or narrower towards apices,
scaly or smooth 3
3. Involucre cylindrical; ligules white H. stenocephala [taraxacoides]
Involucres campanulate-cylindrical, campanulate to hemispherical; ligules yellow (rarely
white) 4
4. Plants 1.5 cm tall; phyllaries with both whip and shaggy hairs H. mucida
Plants 3–13 cm tall; phyllaries glabrous or with only only hair type 5
5. Leaves undivided, margins entire or dentate 6
Leaves pinnatipartite to pinnatisect
H. echegarayi
6. Outer phyllaries lanuginous (whip hairs) towards apex H. eriolaena
Outer phyllaries glabrous or setulose (shaggy hairs) 7
7. Leaves linear-lanceolate or elliptic-lanceolate H. sessiliflora
Leaves oblong
H. hohenackeri
8. Ligules white H. albiflora
Ligules yellow 9
9. Capitula sessile; involucre campanulate H. meyeniana
Capitula usually pedicellate; involucre cylindrical-campanulate
H. eremophila
10. Cauline leaves lobed or pinnatisect H. chillensis
Cauline leaves linear
H. elata
*Hypochaeris acaulis (J. Rémy) Britton, Bull. Torrey Bot. Club 19(12): 371 (1892).
Achyrophorus acaulis J. Rémy in Gay, Fl. Chil. 3: 448 (late 1848 or early 1849). Type: ‗Se cria en los prados
pantanosos de las altas cordilleras de Talcaregue, provincia de Colchagua. Florece en febrero.‘ Type
material presumably in P; isotype: K (q.v. Urtubey et al., 2009: 710).
Argentina, ?Bolivia (?), Chile. Note: Although cited by Foster (1958) Bortiri (1999: 7–8) indicated that this
species was only native in Argentina and Chile, further confirmed by Urtubey et al. (2009). It remains to be
seen whether this species is present in Bolivia.
Marshy areas, damp meadows, stream banks, Araucaria woodland.
