Involucres campanulate, 12–16 mm tall 25–35 mm diam.; ray florets 12–25
S. foetida var. panamensis
Simsia dombeyana DC., Prodr. 5: 578 (1836). Type: ‗– in Amer. austr. verisim. in Peruviâ legit Dombey [12]. ...
(v.s. comm. à Mus. reg. Par.)‘. Holotype: P; isotype: Bú, G-DC, MPU, P, US (fragment, but s.n.).
*Encelia hirsuta Kuntze, Revis. Gen. Pl. 3(3): 145 (1898). Type: ‗Argentina: Dique bei Cordoba und westliche
Pampas 34. Ausserdem gesehen im Berl. bot. Museum von Ascochinga in Sierra de Cordoba (Lorentz),
auch aus Peru (Dombey) eine seltenere Form mit wenigen Strahlblüten = f. radiata, und von Charthagena de
Columbia (Billberg.). Syntypes: Bú.‘ Note: With the exception of the Dombey collection (see following forma)
the remaining collections are considered syntypes. According to Wetter & Zanoni (1985: 330) there are two
sheets of the Kuntze collection in NY, cited as ‗ARGENTINA. Dique bei Córdoba und westliche Pampas, 34,
Dec 1891, Kuntze s.n. (2 sheets).‘ Lectotype (selected by Spooner, 1990: 59): US (701505); isolectotypes: GH
(6573 – fragment ex US), NY (00168355, 00168356), US (701506).
Encelia hirsuta Kuntze f. radiata Kuntze, Revis. Gen. Pl. 3(3): 145 (1898). Types: ‗... auch aus Peru (Dombey) eine
seltenere Form mit wenigen Strahlblüten = f. radiata, ... ‗ Holotype: Bú; isotypes: G-DC, MPU, P, US
(fragment of P material, but s.n.). Note: Robinson (2006: 105) noted this collection as ‗Dombey 12‘, the type
of de Candolle‘s name, yet apparently cited differing isotypes – ‗G-DC, GH, MO, NY, TEX, P, frag. US.‘,
having previously noted photographs of the holotype in ‗CM, GH, TEX‘, and of the isotype in ‗GH, MO,
NY, TEX‘.

Simsia foetida (Cav.) S. F. Blake var. panamensis (H. Rob. & Brettell) Spooner, Syst. Bot. Monogr. 30: 72
(1990).
Simsia panamensis H. Rob. & Brettell, Phytologia 24(5): 372 (1972). Type: ‗PANAMA: Panama: Bella Vista,

Panama, Venezuela, ?Bolivia (Santa Cruz, Tarija).
Open areas in tropical deciduous forest, roadsides.
0–500 m.
November–April.
Note: According to Spooner (1990: 73) the Bolivian material may well represent a new taxon but since
material was limited he preferred to recognize it as the variety of S. foetida, although differing in some
characters. The following two collections were cited by Spooner: SANTA CRUZ: between Charagua & Izozog,
Cárdenas 2666 (US).–TARIJA: Fortín Crevaux, Fries 1645 (US).
Smallanthus MacKenzie in Small, Man. Southeast. Fl. : 1406 (1933).
Type: Osteospermum uvedalia L. = Smallanthus uvedalia (L.) Mackenzie
