92. Cnidoscolus tubulosus (Müll.Arg.) I.M.Johnst., Contr. Gray Herb. View in CoL 68: 86 (1923).— Cnidoscolus tubulosus var.

tubulosus — Jatropha tubulosa Müll.Arg., Linnaea View in CoL 34: 212 (1865). Type:— MEXICO. Without locality, without date,

M. Sessé & J. M. Mociño s.n. (lectotype G-DC-00319828, designated by Breckon (1979); isolectotypes G-00434341!,

G-00434342!, G-00434343!, G-00434344!).

Jatropha tubulosa var. quinqueloba Müll.Arg., Linnaea View in CoL 34: 212 (1865).— Cnidoscolus jurgensenii (Briq.) Lundell, Bull. Torrey Bot. View in CoL Club 72: 324 (1945).— Jatropha jurgensenii Briq., Ann. Cons. Jard. Bot. Geneve View in CoL 4: 229 (1900). Type:— MEXICO. Oaxaca: Sierra San Pedro Nolasco, Talea c., 1843–1844, C. Jürgensen 599 (lectotype G-00434346!, designated by Breckon (1979); isolectotypes BM-000820482!, G-00434345!,F-V0056784F!, K-000254126!, K-000254127!).

Jatropha tubulosa var. septemloba Müll.Arg., Linnaea View in CoL 34: 212 (1865). Type:— GUATEMALA. Without locality, without date, M. Sessé & J.M. Mociño s.n. (holotype G-00319828!). Breckon (1979) argued that this specimen is actually from Mexico and not Guatemala.

Cnidoscolus cordifolius (Pax) I.M.Johnst., Contr. Gray Herb. View in CoL 68: 86 (1923).— Jatropha cordifolia Pax, Pflanzenr. IV. View in CoL 147. I (Heft 42): 107 (1910). Type:— GUATEMALA. Santa Rosa: Santa Rosa, April 1892, E.T. Heyde & E. Lux 3474 (lectotype GH!, designated by Breckon (1979) as neotype; isolectotypes M-0067034!, US-00027213 !).

Cnidoscolus tomentosus Lundell, Bull. Torrey Bot. View in CoL Club 72: 332 (1945). Type:— MEXICO. Oaxaca: Santa María del Tule , 17 October 1943, E. Hernández X. s.n. (holotype LL-00256919!; isotype LL-00371626!, NY-00246402 !).

Distribution:— El Salvador, Guatemala, Honduras, Mexico.

Notes:— The taxonomy of this species is complicated, and as discussed by Breckon (1979), it has been full of misunderstandings. We consider that it belongs to sect. Calyptrosolon and is restricted to Mexico and Central America. Plants from South America have been recognized as Cnidoscolus tubulosus var. trilobus (e.g., Fernández Casas 2007e, Novara 2013). However, both morphology and molecular data (Maya-Lastra & Steinmann in prep.) support its placement in sect. Jussieuia , and it is here treated as a synonym of Cnidoscolus urens . More studies of C. tubulosus would be beneficial, in particular its relationship with the morphologically similar C. autlanensis .
