ABSTRACT:
The genus Pseudohydrosme was described by Engler (1892) from incomplete material with two species native in Gabon: P. gabunensis Engl. and P. buettneri Engl. During my collecting trip to Gabon in the year 1973, I especially looked for these species and I scheduled my visit to coincide with the flowering time of the two aroids, but they are so rare that I only found two specimens of P. gabunensis.
