Nomenclatural novelties in Euphorbiaceae

Replacement names Croton lallanii R.Kr.Singh, C. vishwanathii R.Kr.Singh and Euphorbia charitontcevii R.Kr.Singh are proposed here for the illegitimate names Croton chevalieri Gagnep., C. insignis Glaz. ex Sodré & M.J.Silva and Euphorbia pseudoesula Charit. respectively. In the genus Euphorbia L., a new name E. sangeetae R.Kr.Singh is proposed here for Stenadenium spinescens Pax. Two new combinations Euphorbia compacta (N.E.Br.) R.Kr.Singh and E. compacta var. rubra (S.Carter) R.Kr.Singh are made here for Synadenium compactum N.E.Br. and S. compactum var. rubrum S.Carter respectively. A new combination and status Euphorbia sangeetae var. elegans (S.Carter) R.Kr.Singh is made for Monadenium elegans S.Carter. In addition, to fix the identity and to avoid the misapplication of names, lectotypes are designated for Synadenium compactum N.E.Br. and Stenadenium spinescens Pax.
