focus on... Recently described new Peperomia species
It appears that the extending scientific interest in the genus Peperomia during the last decade is resulting in the publication of a substantially higher number of new taxa.

After the publication of 3 new Peperomia species in 2006 (P. ankaranensis, P. erythrocaulis, P. richardsonii) and another 3 in 2007 (P. cuchumatanica, P. linaresii, P. moralesii), the year 2008 yielded 11 new taxa (P. ciliato-caespitosa, P. chutanka, P. dolabriformis var. lombardii, P. dolabriformis var. multicaulis, P. gracilispica, P. kjellii, P. magnifoliiflora, P. parcipeltata, P. pinoi, P. pseudophyllantha, P. sagittata).
In 2011 not less than 29 new species were described (from Mexico: P. albonervosa, P. basiradicans, P. cavispicata, P. elatior, P. exclamationis, P. occulta, P. putlaensis, P. questionis,P. tepoztecoana; from Peru and Bolivia: P. ayacuchoana, P. cerrateae, P. gigantea, P. jalcaensis, P. klopfensteinii, P. ocrosensis, P. pseudoverruculosa, P. pugnicaudex, P. purpureonervosa, P. querocochana, P. radiatinervosa, P. wernerrauhii, P. umbrosa; from Belize and Costa Rica: P. paramuna, P. toledoana, P. unifoliata); from Colombia: P. rivulamans.
In 2012 a series of window-leaved succulent species were described (P. callana, P. ciezae, P. erosa, P. ferreyrae var. musifolia, P. maijeri, P. mantaroana, P. mathieui, P. mitoensis, P. palmiformis, P. samainiae, P. selenophylla).
Two Brazilian species were described in 2013 (P. diamantinensis, P. cruzeirensis).
From Mexico three species were described in 2015 (P. chazaroi, parastriata, P. vazquezii) while from Brazil two new species were described in 2016 (P. epipremnifolia, P. sulbahiensis).

One has to take into account that quite some time can pass between the actual discovery of a new species and the eventual publication of its description. First of all there is the need to search for and to compare with possible existing herbarium material. Related data have to be gathered, referenced and illustrations have to be made. After the manuscript is written and submitted, the peer reviewing process might lead to additions or modifications before the protologue is finally approved for publication in a scientific journal. We estimate that at this very moment the manuscripts of about 60 new species descriptions are awaiting their finalization.
