Smallanthus connatus (Spreng.) H. Rob., Phytologia 39(1): 49 (1978).

Gymnolomia connata Spreng., Syst. Veg. 3: 610 (1826). Type: Brasil. Sello.

Polymnia silphioides DC., Prodr. 5: 516 (1836). Type: in Brasili prov. Rio-Grande (h. Mus. imp. Bras. n. 885!). Holotype: G-DC; isotype: P.

Polymnia macroscypha Baker in Mart., Fl. Bras. 6(3): 158 (1884). Types: YT'Habitat in pascuis et ruderatis Brasiliae, in prov. Minas Geras ad Caldas: Regnell I. n. 195 ex parte!, Lindberg n. 5!; praeterea: Weir n. 505! Note: Wells (1965: 149) noted simply ''Isotype, F! without noting which of the collections cited by Baker this was.

Polymnia silphioides DC. var. perennis Bettfr., Fl. Argent. 2: 116 (1900). Type: Palermo, San Isidro. Bettfreunds herbarium and types are listed as B, SI in TL II. It is probable that the holotype is in SI.

Polymnia andrei Arechav., Ann. Mus. Nac. Montevideo 2, 1: 35 (1905). Type: Vive en parajes frescos herbosos, orillas de selvas etc. Los ejemplares del Herbario proceden de Tacuarembo, como la dejemos dicho al principio. Florece por los meses de noviembre y diciembre. Wells (1965) cited simply Type, W. However, it more than likely that the type collections are in Uruguay in MVM.

Polymnia connata (Spreng.) S. F. Blake, Contr. U. S. Natl. Herb. 26: 238 (1930).

Argentina, Bolivia (Tarija), Brazil, Paraguay, Uruguay.

Robinson (1978: 49), like Wells (1965: 149), did not cite Bolivia in the distribution of this species.

Smallanthus glabratus (DC.) H. Rob., Phytologia 39(1): 49 (1978).

*Polymnia glabrata DC., Prodr. 5: 515 (1836). Type: K in Chile legit cl. Haenke. ... (v.s. in h. Haenke cl. de Sternberg comm.). Holotype: PR; isotype: G-DC. Foster (1958: 216) recorded this species for Bolivia, under Polymnia, however, it is only known from Chile and Peru. Although Robinson (1978: 49) cited Chile, Ecuador and Peru, he later (2006: 109-110) indicated that material referable to this taxon was either S. fruticosus (Benth.) H. Rob. or S. pyramidalis (Triana) H. Rob. - neither of which are known from Bolivia. Wells (1965: 156-158) treated four species in the Polymnia glabrata complex, and it is likely that material referable to this name by Foster is actually Smallanthus parviceps.

Smallanthus parviceps (S. F. Blake) H. Rob., Phytologia 39(1): 51 (1978).

Polymnia parviceps S. F. Blake, Contr. U.S. Natl. Herb. 22: 604 (1924). Type: ... collected at Torontoy, in the Urubamba Valley, Peru, altitude about 2,400 meters, May 20, 1915, by O. F. Cook and G. B. Gilbert (no. 818). Holotype: US (603981).

Bolivia (La Paz), Peru.

Vernacular name: Yarita (Blake, 1924: 605).

Smallanthus riparius (Kunth) H. Rob., Phytologia 39(1): 51 (1978).

Polymnia riparia Kunth in Humb., Bonpl. & Kunth, Nov. Gen. Sp. Pl. 4 (ed. folio): 222 (1818). Type: [Colombia:] Crescit in Regno Novo-Granatensi, ad ripam fluminis Magdalen, inter Cascajo et Angostura de Carare. K Floret Majo. [Humboldt & Bonpland ''Bonpl. mss. 1640. prope Cascajo, Rio Magdalena. Maj. 1801] Holotype: P-Bonpl.

Bolivia (La Paz, Oruro), Colombia, Ecuador, Guatemala, Peru, Venezuela. Robinson (2006: 115) suggested only Colombia and Ecuador, in contrast to his earlier account (Robinson, 1978: 51) with a far wider range.

Smallanthus siegesbeckius (DC.) H. Rob., Phytologia 39(1): 51 (1978).

*Polymnia siegesbeckia DC., Prodr. 5: 516 (1836). Type: in Brasili circa Rio-Janeiro legit cl. Gaudichaud. ... (v.s. comm. cl. inv.). Holotype: G-DC.

Bolivia (La Paz, Santa Cruz), Brazil, Paraguay, Peru.

Smallanthus sonchifolius (Poepp.) H. Rob., Phytologia 39(1): 51 (1978).

Polymnia sonchifolia Poepp., Nov. Gen. Sp. Pl. 3: 47, tab. 254 (1843). Type: Crescit in montibus calcareis herbidis Peruviae orientalis ad Cassapi. Januario florebat.

Helianthus esculentus Warsz. ex Otto & Dietr. Allg. Gartenz. (Otto & Dietrich) 20(No. 37): 293 (1852), nom. illegit., later homonym, non Rottb. (1778). Type: [Bolivia:] ... in der Landessprache Jaccon gennant, ... [Warszewicz s.n., s. dat.] Waszewicz clearly collected this taxon in the Sorata area of La Paz, before June 1852. The top set may well have been deposited in B. Note: Whilst not mentioned by Robinson (2006: 115), it is quite likely that this name belongs in synonymy here, especially because of the reference to the common name - Jaccon.

*Polymnia edulis Wedd., Ann. Sci. Nat. Bot., Ser. 4, 7: 114 (1857). Type: [Colombia:] Sponte crescit prope Quetame, in declivitate orientali Andium Bogotensium, ad altitudinem 2000 metr. (Triana); colitur in regione subtropica Peruviae et Novae Granatae, ubi, teste cl. Triana, nuncupatur Jiquima et Jiquimilla. Holotype: P.
