Desbordesia insignis Pierre , tab. Herb. L. Pierre, del. E. Delpy 2/1901, Fig. 4 .

Untill now the monotypic genus Desbordesia is attributed to VAN TIEGHEM, who “validated” PIERRE’ s name in 1905. But the same author stated there, that the illustration of DELPY was distributed in February 1901 to the main “herbiers publics”, which means the publication of an illustration with analysis, hence a valid publication. It has been located at BR and P. Between February 1901 and 1905, ENGLER (1902) described the single species as Irvingia glaucescens which became the basionym of Desbordesia glaucescens (Engl.) Tiegh. under which name the species is known at present. The correct name, however, is:

Desbordesia insignis Pierre , tab. Herb. L. Pierre, del. E. Delpy 2/1901 (coll. Klaine 1930).

Irvingia glaucescens Engl., Bot. Jahrb. Syst. 32: 124 (1902).

Desbordesia glaucescens (Engl.) Tiegh., Ann. Sc. Nat. Bot. , sér. 9, 1: 290 (1905); Aubréville , Flore Gabon 3: 29, pl. 5 (1962); Harris, Bull. Jard. Bot. Belg. 65: 147 (1996). — Type: see HARRIS 1996.

Klainedoxa gabonensis Pierre , tab. Herb. L. Pierre, del. E. Delpy 17/2/1896, Fig. 5 .

According to HARRIS (1996, 1999), Pierre ex Engl. are the authors of the genus Klainedoxa and its type species, but AUBRÉVILLE (1962) cited both correctly as from PIERRE alone, based on PIERRE’ s publication of 1896a. DELPY’ s illustration with analysis, dated 17 February 1896 (at present found in BR, K, P), was sent to Berlin, together with a duplicate of Klaine 188 and a full description of the genus and the species in DELPY’ s handwriting, signed “Saint Mandé, 17 février 1896, L. Pierre” ( PIERRE 1896a: 1236). ENGLER, in his publication of April 1896 ( ENGLER 1896: 227), refers to PIERRE and it is clear that he based Klainedoxa Pierre on what he had received from PIERRE: a description of the genus and of its single species together with DELPY’ s illustration and a duplicate of the type Klaine 188 ( PIERRE 1896a: 1236). PIERRE’ s description in print (1896a) appeared shortly after ENGLER’ s. The correct author for the genus Klainedoxa and the species K. klaineana , however, is PIERRE.
