Warming (1880) used the collection Glaziou 10472 to describe the new variety Maytenus gonoclados var. glaziovii , distinguished from the typical variety by wider and smaller leaves.The taxon resembles Monteverdia gonoclados (Mart. 1841: 89) Biral (2017: 689) in that it has inflorescences in cymes and slightly crenate leaf margin but is distinguished by its subwinged young twigs and pauci-flowered inflorescences with reduced peduncle, shorter than pedicels. The young twigs in Monteverdia gonoclados are flattened or carinate and the inflorescences multi-flowered with an evident peduncle. Eight specimens from Glaziou 10472 were examined and it is concluded that the variety is conspecific with Monteverdia subalata , a shrub endemic from the high altitude areas of Brazil’s Atlantic rainforest in the states of Minas Gerais, Rio de Janeiro and São Paulo. This taxonomic decision is against Carvalho-Okano (1992) and Carvalho-Okano & Leitão-Filho (2004), who considered it a synonym of Maytenus gonoclados based on leaf size and the examination of only two specimens deposited in LE and S (see Carvalho-Okano 1992: 179). The specimen C10023018, originally from Herbarium Eug. Warming and currently deposited in C, is selected as lectotype for Maytenus gonoclados var. glaziovii and not considered the holotype according to McNeill’s (2014) recommendations.
