Bolivia (?), Chile, Peru, Ecuador, Mexico. Note: Robinson (2006: 98) suggested that this species occurs from
Mexico south to Chile – presumably occurring in Bolivia!

*Siegesbeckia flosculosa L‘Hérit., Stirp. Nov. : 37, t. 19 (1786). Note: Foster (1958: 218) cited this species for
Bolivia, although it is not immediately clear on what collection/s, or reference, this is based. Humbles (1972)
and Robinson (2006) only recorded the species for Ecuador and Peru.
Siegesbeckia jorullensis Kunth in Humb., Bonpl. & Kunth, Nov. Gen. Sp. Pl. 4 (ed. folio): 223 (1818). Type:
‗Crescit in monte ignivomo Mexicano, Volcan de Jorullo, alt. 530 hex. 0 Floret Septembri.‘ Holotype: P-Bonpl.
Sigesbeckia cordifolia Kunth in Humb., Bonpl. & Kunth, Nov. Gen. Sp. Pl. 4 (ed. folio): 222 (1818). Type:
‗Crescit in alta planitie Bogotensi, prope urbem Sanctæ Fidei, alt. 1370 hex. 0 Floret Julio.‘ Holotype: P-
Bonpl.
Siegesbeckia droseroides Sweet, Hort. Brit. : 235 (Aug. 1826), nom. nud. Note: Sweet‘s listing is tabular in form
and considered invalid in the current Vienna Code (McNeill et al., 2006), which cited Hortus Brittanicus ed.
3 as an example. However, the entry here refers to the British Flower Garden plate by Sweet, as the plate
refers to Hortus Britannicus, suggesting that Sweet was writing them both at the same time, except one was
published a while later.
Siegesbeckia droseroides Sweet, Brit. Fl. Gard., ser. 1, 3: t. 203 (May 1827). Type: ‗The present plant is native of
Mexico, ...; many plants of it were raised at the Nursery of Mr. Colville, in 1825, from seeds given him by
Mrs. Manners Sutton, Lady of the Archbishop of Canterbury, who received them from Mexico; from one of
those our drawing was made the following Autumn, when several of them flowered.‘ Holotype: unknown
but probably CGE? or MV? where the types for cultivated material can be found.

Scrub, pasture, forst margins, montane forest.
2700–3500 m.
Probably flowering throughout the year.
Robinson (2006: 102) noted that his treatment was interpreted more broadly that in Schulz‘s (1987) treatment
by sinking S. bogotensis and S. cordifolia into S. jorullensis, a slightly expanded concept adopted by Humbles
(1972).
