Least Concern (LC) (Cosiaux et al. 2019a g). Uses in Cameroon. None reported. Notes. <i>Piptostigma fugax</i> resembles <i>P. oyemense</i> in having a single-flowered inflorescence and flowers with 1 to 3(4) carpels, a unique combination of characters in <i>Piptostigma</i>. However, <i>P. fugax</i> has obovate leaf blades, while <i>P. oyemense</i> has elliptic leaf blades.
