5. Euphorbia cordeiroae Carrillo-Reyes & Steinmann (2011: 170) . Type:— BRAZIL. Goiás: Alto Paraíso de Goiás, estrada para Colinas , a 1 km da entrada do Parque Nacional da Chapada dos Veadeiros, 20 November 1987, I. Cordeiro, M.C.H. Mamede, M.G. Sajo & E.M. Varanda 388 (holotype SP!, isotype IEB).

Distribution and habitat:— Euphorbia cordeiroae was first published as endemic from “Chapada dos Veadeiros”, in northeastern Goiás state, Brazil. We found one collection for São Paulo state, but no information about its habitat is given on the herbarium label. According to the original publication (Carillo-Reyes & Steinmann 2011), the species occurs in cerrado vegetation.

Representative Specimen:— BRAZIL. São Paulo: Itararé , 22 April 1993, C.A.M. Scaramuzza et al. 977 (ESA) .

Taxonomic notes:— Euphorbia cordeiroae is similar to E. rhabdodes and E. elodes , but differs from E. rhabdodes by the number of lateral axes of the pleiochasia (3 in E. cordeiroae vs. 5 in E. rhabdodes ), leaf margin (not revolute in E. cordeiroae vs. revolute in E. rhabdodes ) and seed coat (inconspicually verrucose in E. cordeiroae vs. ruminate in E. rhabdodes ). Euphorbia elodes , which also possess cyathia arranged in pleiochasia with 3 lateral axes, differs from E. cordeiroae due to the shape of the cyathophylls (linear in E. cordeiroae vs. elliptic to obovate in E. elodes ), stipules (lateral and glanduliform in E. cordeiroae vs. absent in E. elodes ) and the perianth-like whorl on the pistillate flower (well developed in E. cordeiroae vs. absent or poorly developed in E. elodes ).
