However, the species is apparently relatively common in a restricted area of Bolivia, suggesting that the species is probably of Least Concern (LC). <i>Discussion</i>. Harms (1920: 351) described <i>Acacia fiebrigii</i> from the single collection <i>Fiebrig 3113</i>, not specifying any herbarium of deposit. He quickly replaced the epithet (Harms, 1920: 450), which was superfluous against an earlier <i>A. fiebrigii</i> (Hassler, 1910). The current lectotypification of the replacement name <i>A. feddeana</i> clarifies the herbarium of deposit at B, at the principal institution of the describing author. In the year following the publication of Harms’s new name <i>Acacia feddeana</i>, Spegazzini (1921: 219) also published a replacement name for Harms’s later homonym <i>A. fiebrigii</i>. This was included in discussion under Spegazzini’s treatment of <i>A. recurva</i> Benth., and <i>A. molfinoi</i> was clearly associated with <i>A. fiebrigii</i> as its replacement, which was unfortunately too late and therefore illegitimate and superfluous. One pair of pinnae separates <i>Pseudosenegalia feddeana</i> from <i>P. riograndensis</i>. <i>Specimens examined</i>. BOLIVIA. <b>s. loc.:</b> 1 9 9 2, <i>G.
