REMARKS

Guillaumin (1911a) published the name “ P. gatopensis Vieill. mss.” and mentioned the collection Vieillard 2655, which has been treated in several herbaria as the type. However, since the name was not validly published in 1911, this collection is not the type.

In 1928, Engler included the name “ P.gatopensis Vieill. ” in his key to Pancheria but as he did not distinguish it morphologically from P.vieillardii , the name was not validly published by him either.

In 1941, Guillaumin published “ P. gatopensis Vieill. mss. sp. nov.” accompanied by a description in Latin. Although he stated that P. gatopensis “= P. lanceolata Vieill. mss., non P. alaternoides var. lanceolata Pampan. ”, this does not invalidate the name P. gatopensis , because the type of P. lanceolata (Pamp.) Baker f. does not in fact belong to the taxon he called P. gatopensis .

In the protologue, Guillaumin (1941) referred to specimens “cités comme P. alaternoides var. lanceolata auxquels il faut ajouter: Wagap, Poume (Deplanche 62) et l’échantillon (Lecard [sic] sans no.) signalé comme P. ferruginea ”. The specimens “cités comme P. alaternoides var. lanceolata ” can not be those listed in Guillaumin (1941), as this name was specifically excluded from his concept of P. gatopensis in 1941, and so must be those he listed in 1911a, which were: “Poume, Wagap [Vieillard 581, 589, 2064], baie Ouié [Balansa 195], Mt Mi [Balansa 1068], embouchure du Houailou [Balansa 2309a], Canala [Balansa 2309], Mt Mou [Balansa 2858], Poyo [Cribs 1211], Mt Koghi [Pancher]”. Together with Deplanche 62 and Lécard s.n., they are all syntypes.

Since Guillaumin (1941) made no reference to Vieillard 2655, which he had cited in 1911a as Pancheria gatopensis , this collection is not a syntype, even though it is the material that Vieillard collected near Gatope and labelled “ P.gatopensis ”. For this reason, the epithet “ gatopensis ” is attributed to Guillaumin alone, and not to “Vieill. ex Guillaumin”.

Most of the lectoparatypes of Pancheria gatopensis at P are conspecific with the lectotype although the only Pancher sheet at P labelled Koghi (“Cougui”) has the numbers 46481 and “ coll. de bois no. 1293 ” and is a mixture of P. gatopensis and P. ferruginea .
